Answer:

The amount of flour added to each box was 0.64 kg

Step-by-step explanation:

Let

x ----> the amount of flour added to each box in kg

Remember that

1 kg=1,000 g

8,600 g=8,600/1,000=8.6 kg

we know that

The linear equation that represent this situation is

(8.6+x)=4(1.67+x)

Solve for x

8.6+x=6.68+4x

4x-x=8.6-6.68

3x=1.92

x=0.64 kg

To solve this problem, we'll use algebra. Let's denote the initial amount of flour in Box A as A and in Box B as B. Also, let the amount of flour added to each box be x (in kilograms).
Given:
A = 1.67 kg
B = 8600 g, which we need to convert to kilograms. Since 1 kilogram is 1000 grams, we get:
B = 8600 / 1000 kg
B = 8.6 kg
After adding x kg of flour to each box, Box B contains 4 times as much flour as Box A. Therefore, we can set up the following equation:
B + x = 4(A + x)
Now, we plug in the values for A and B:
8.6 + x = 4(1.67 + x)
Distribute the 4 on the right side of the equation:
8.6 + x = 6.68 + 4x
Now we'll consolidate like terms:
8.6 - 6.68 = 4x - x
1.92 = 3x
To solve for x, we divide both sides by 3:
x = 1.92 / 3
x = 0.64 kg
So 0.64 kg of flour was added to each box.

Answer:

96°

Step-by-step explanation:

An angle formed by a chord and a tangent that intersect on a circle is half the measure of the intercepted arc.

x = 168/2 = 84°

A straight angle is 180 degrees

y = 180 - x = 180 - 84 = 96°

Answer:

C

Step-by-step explanation:

Note that if x = h is a root of a polynomial f(x) then f(h) = 0

Note the sum of the coefficients of the given polynomial

x³ + 4x² + x - 6 is

1 + 4 + 1 - 6 = 0

Hence x = 1 is a root( zero) and (x - 1) is a factor

For this case we must find an expression equivalent to:

[tex]\sqrt [4] {f}[/tex]

By definition of properties of powers and roots we have:

[tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]

So, rewriting the given expression we have:

[tex]f ^ {\frac {1} {4}}[/tex]

a. Arithmetic

b. [tex]a_{n} = a_{n-1} + 15[/tex]

c. [tex]a_{n} = 15n + 125[/tex]

Step-by-step explanation:

A sequence is arithmetic when the difference between one term and the next is a constant. On the other hand, a sequence is geometric when the next term is found by multiplying the previous by a constant.

In this case, the next term of the sequence can be found by adding $15. Therefore, the sequence is ARITHMETIC ✔️

The recursive formula will be the following: [tex]a_{n} = a_{n-1} + 15[/tex]

The explicit formula is the following: [tex]a_{n} = 15n + 125[/tex]

Answer:

The net of a rectangular pyramid is consisting of a rectangle, for the base, and there are 4 more triangles that make up the lateral faces, and the triangles make the pyramid.

Answer:

Explanation:

1) Vertex form of the function that represents a parabola.

The general form of a quadratic equation is Ax² + Bx + C = 0, where A ≠ 0, and B and C may be any real number. And the graph of such equation is a parabola with a minimum or maximum value at its vertex.

The vertex form of the graph of such function is: A(x - h)² + k

Where, A a a stretching factor (in the case |A| > 1) or compression  factor (in the case |A| < 1) factor.

2) Find the vertex of the first function, f(x) = x²

This is the parent function, for which, by simple inspection, you can tell h = 0 and k = 0, i.e. the vertex of f(x) = x² is (0,0).

3) Find teh vertex of the second function, g(x) = x² -10x + 2

The method is transforming the form of the function by completing squares:

That is the searched vertex form: g(x) = (x - 5)² - 23.

From that, using the rules of translation you can conclude immediately that the function f(x) was translated 5 units horizontally to the right and 23 units vertically downward.

Also, by comparison with the verex form A(x - h)² + k, you can conclude that the vertex of g(x) is (5, -23), and that means that the vertex (0,0)  was translated 5 units to the right and 23 units downward.

Answer:

The correct answer is the last one, at the bottom.

Step-by-step explanation:

You need to change in f(x) every 'x' for the expression given in g(x), since you have to build a compound function (fºg)(x).

So F(g(x))= F(x4)=-9*(x4)+3

Resulting (fºg)(x)=-9x4+3 (I only changed 'x' for 'x4', the term +3 is not changed since that is not a variable term, is just a constant number.

Answer:

The correct option is D) Two pizzas are shared equally among zero people, and you want to know how much each person gets.

Step-by-step explanation:

Consider the provided information,

We need to identify the option which has no solution,

Consider the option A)

Six pizzas are shared equally among three people, and you want to know how much each person gets.

We can find how much each person gets by dividing the number or pizza with number of people:

Each person gets = 6/3 = 2

That means each person gets 2 pizza.

The problem has a solution.

Consider the option B)

Three pizzas are shared equally among two people, and you want to know how much each person gets.

We can find how much each person gets by dividing the number or pizza with number of people:

Each person gets = 3/2 = 1.5

That means each person gets 1.2 pizza.

The problem has a solution.

Consider the option C)

Zero pizzas are shared equally among three people, and you want to know how much each person gets.

We can find how much each person gets by dividing the number or pizza with number of people:

Each person gets = 0/3 = 0

That means each person gets 0 pizza.

The problem has a solution.

Consider the option D)

Two pizzas are shared equally among zero people, and you want to know how much each person gets.

We can find how much each person gets by dividing the number or pizza with number of people:

Each person gets = 2/0 = No solution

As we know any number divided by 0 has no solution.

Thus, the problem has no solution.

Hence, the correct option is D) Two pizzas are shared equally among zero people, and you want to know how much each person gets.

Answer:

[tex]y=\frac{5}{4}x+\frac{15}{4}[/tex]

Step-by-step explanation:

x | y

-------

1     5

5   10

9    15

13   20

This one is linear because as x goes up by the same number so does y. So the ratio of difference of y to difference of x is the same per pair of points.

So a linear equation in slope-intercept form is y=mx+b where m is the slope and b is the y-intercept.

To find the slope, I'm going to line up the points vertically and subtract, then put 2nd difference over 1st difference. Like so,

( 1    ,   5)

-( 5   ,  10)

----------------

-4          -5

So the slope is 5/4 which makes sense since the y's are going up by 5 each time and the x's are going up by 4 each time.

So we have m=5/4. Let's plug that into our y=mx+b.

y=5/4 x+b

To find b, we need to use y=5/4 x+b along with one of the given points.

Choose; it doesn't matter.  I like (1,5) I guess.

y=5/4 x +b with (1,5)

5=5/4 (1)+b

5=5/4    +b

Subtract 5/4 on both sides:

5-5/4=b

20/4-5/4=b  (Found a common denominator)

15/4=b

The y-intercept is 15/4 so b=15/4.

So the equation for the line in slope-intercept form is y=5/4 x +15/4.

[tex]y=\frac{5}{4}x+\frac{15}{4}[/tex]

Answer:

It is linear.

The equation is 5x - 4y = -15.

Step-by-step explanation:

If it is linear then the slope between consecutive points will be the same.

Slope = (10-5)/(5-1) = 5/4.

slope = (15-10)/ (9-5) = 5/4

slope = (20-15)/ (13-9) = 5/4.

So the data relationship is linear.

y - y1 = m(x - x1)

Using the point (1, 5)

y - 5 = 5/4(x - 1)

y = 5/4x - 5/4 + 5

y = 5/4x + 15/4

4y = 5x + 15

5x - 4y = -15.

Answer: I think it’s t II k

Step-by-step explanation:

If m is parallel to k and m is also parallel to ℓ, then by the transitive property of parallel lines, k must be parallel to ℓ.

If m ∥ k and m ∥ ℓ, then k is parallel to ℓ. In terms of geometry, when a line m is parallel to lines k and ℓ, and all the lines are coplanar, then lines k and ℓ must be parallel to each other as well. This is due to the transitive property of parallel lines which states that if two lines are parallel to the same line, they are parallel to each other. An example of this could be railway tracks: if the sleepers (the wooden blocks) are considered to be line m, which is parallel to both rails (k and ℓ), the rails (k and ℓ) have to be parallel to each other in order for the train to travel smoothly.

Answer:

Summation notation is:

[tex]\sum_{n=1}^{16}[5(x-1)-9][/tex]

If you prefer it a little more simplified:

[tex]\sum_{n=1}^{16}(5x-14)[/tex]

Step-by-step explanation:

First my favorite part, finding a pattern between the consecutive terms.

This is an arithmetic series because the terms are going up by 5 each time.

So arithmetic sequence, think linear equations:

x     |      y

1            -9

2           -4

3             1

4             6

..................

n             66

We are going to have to find that n but will will eventually...

The equation for a line in point slope form is [tex]y-y_1=m(x_x_1)[/tex] where [tex](x_1,y_1)[/tex] is a point on the line and m is the slope.

We are already have the slope is 5 (the slope is the common difference in arithmetic sequence).

I'm going to use the first point (1,-9).

So the equation in point slope form is [tex]y-(-9)=5(x-1)[/tex]

Subtract 9 on both sides:

[tex]y=5(x-1)-9[/tex]

Now we need to know how many terms we are adding so what is x if y=66.

[tex]66=5(x-1)-9[/tex]

Add 9 on both sides:

[tex]75=5(x-1)[/tex]

Divide both sides by 5:

[tex]15=x-1[/tex]

Add 1 on both sides:

[tex]16=x[/tex]

We have 16 terms in this sequence where the 16th term is 66.

Summation notation is:

[tex]\sum_{n=1}^{16}[5(x-1)-9][/tex]

You could simplify the 5(x-1)-9.

Distribute:  5x-5-9

Add like terms:  5x-14

Step-by-step explanation:

Answer:

cosine theta equals plus or minus two times square root of two over three, tangent theta equals plus or minus square root of two over four

Step-by-step explanation:

Given:

sinθ=1/3

θ=19.47 degrees

then

cosθ= cos(19.47)=0.942 = 2(√2/3)

tanθ=tan(19.47)=0.35= √2/4

Hence option two is correct:cosine theta equals plus or minus two times square root of two over three, tangent theta equals plus or minus square root of two over four!

Answer:

So second choice.

[tex]\cos(\theta)=\pm \frac{2\sqrt{2}}{3}[/tex]

[tex]\tan(\theta)=\pm \frac{\sqrt{2}}{4}[/tex]

Step-by-step explanation:

I'm going to use a Pythagorean Identity, name the one that says:

[tex]\sin^2(\theta)+\cos^2(\theta)=1[/tex].

We are given: [tex]\sin(\theta)=\frac{1}{3}[/tex].

Inserting this into our identity above gives us:

[tex](\frac{1}{3})^2+\cos^2(\theta)=1[/tex]

Time to solve this for the cosine value:

[tex]\frac{1}{9}+\cos^2(\theta)=1[/tex]

Subtract 1/9 on both sides:

[tex]\cos^2(\theta)=1-\frac{1}{9}[/tex]

[tex]\cos^2(\theta)=\frac{8}{9}[/tex]

Square root both sides:

[tex]\cos(\theta)=\pm \sqrt{\frac{8}{9}}[/tex]

9 is a perfect square but 8 is not.

8 does contain a factor that is a perfect square which is 4.

So time for a rewrite:

[tex]\cos(\theta)=\pm \frac{\sqrt{4}\sqrt{2}}{3}[/tex]

[tex]\cos(\theta)=\pm \frac{2\sqrt{2}}{3}[/tex]

So without any other give information we can't know if cosine is positive or negative.

Now time for the tangent value.

You can find tangent value by using a quotient identity:

[tex]\tan(\theta)=\frac{\sin(\theta)}{\cos(\theta)}[/tex]

[tex]\tan(\theta)= \frac{\frac{1}{3}}{\pm \frac{2\sqrt{2}}{3}}[/tex]

Multiply top and bottom by 3 get's rid of the 3's on the bottom of each mini-fraction:

[tex]\tan(\theta)=\pm \frac{1}{2 \sqrt{2}}[/tex]

Multiply top and bottom by sqrt(2) to get rid of the square root on bottom:

[tex]\tan(\theta)=\pm \frac{1(\sqrt{2})}{2\sqrt{2}(\sqrt{2})}[/tex]

Simplifying:

[tex]\tan(\theta)=\pm \frac{\sqrt{2}}{2(2)}[/tex]

[tex]\tan(\theta)=\pm \frac{\sqrt{2}}{4}[/tex]

Since this is an isosceles triangle [two congruent sides], m<B is also 30°. Now, we have to the m<A by using the Interior Angles Theorem [m<1 + m<2 + m<3 = 180°]. So we do this:

60 + m<A = 180; 120 = m<A

I am joyous to assist you anytime.

The correct recursive function is: [tex]\[ f(n) = f(n-1) \times (1 - 0.30) + 25 \][/tex]

Let's break down the problem:

At the start, there are 100 t-shirts in the store (f(0) = 100).

Each month, 30% of the current stock is sold, and 25 new t-shirts arrive.

So, if we denote the number of t-shirts in the store at the beginning of the nth month as f(n), we can represent the recursive relationship as follows:

f(n) = f(n-1) * (1 - 0.30) + 25

This equation means that the number of t-shirts in the store at the beginning of the nth month is equal to 70% of the number of t-shirts at the beginning of the previous month (because 30% were sold), plus 25 (because 25 new t-shirts arrive).

In this function:

- [tex]\( f(n) \)[/tex] represents the number of t-shirts in the store at the beginning of the nth month.

- [tex]\( f(n-1) \)[/tex] represents the number of t-shirts in the store at the beginning of the (n-1)th month.

- [tex]\( (1 - 0.30) \)[/tex] represents 70% of the t-shirts from the previous month remaining after 30% are sold.

- [tex]\( + 25 \)[/tex] represents the 25 new t-shirts that arrive each month.

Complete question: A store had 100 t-shirts. Each month, 30% of the t-shirts were sold and 25 new t-shirts arrived in shipments. Which recursive function best represents the number of t- shirts in the store, given that f(0)=100?

a-f(n)=f(n-1) 0.3+25,n>0

b-f(n)=100-f(n-1) = ( 3.3+25 n>0

c-f(n)=f(n-1) -( 0.7+25 n>0

d-f(n)=100-f(n-1) - C 7+25 n>0

Answer:

C.

Step-by-step explanation:

So there are 20 kids with brown hair and this represents 80% of the class total.

So this means 20=.8n since we don't know the total number of kids.

20=.8n

Divide both sides by .8

25=n

So 25 is the total number of kids.

C. is the answer

You could also setup this equation given that 80% is 80/100:

[tex]\frac{20}{\text{ total }}=\frac{80}{100}

Answer:

Answer is A

Step-by-step explanation:

Answer:

The answer is 2.

2  since 6/4=3/2

Step-by-step explanation:

Since your relation is a direct variation then the points on your line are of the form y=kx where k is the constant of variation (also called constant of proportionality)

If y=kx then y/x=k.

So all the points in this relation since it is a direct variation will be equal to y-coordinate/x-coordinate.

So we are going to solve this proportion:

[tex]\frac{6}{4}=\farc{3}{x}[/tex]

Again I put y/x from each point. They should have same ratio because this is a direct variation.

Cross multiply:

[tex]6(x)=4(3)[/tex]

[tex]6x=12[/tex]

Divide boht sides by 6:

[tex]x=\frac{12}{6}[/tex]

[tex]x=2[/tex]

Answer:

Step-by-step explanation:

You are solving for the direct variation. This means that the amount of change for is consistent for both x & y:

Note: (x , y) & (x₁ , y₁)

(x , y) = (4 , 6)

(x₁ , y₁) = (x , 3)

Set the two equal to each other:

(4 , 6) = (x , 3)

Find common denominators (y). Remember that what you multiply to one you multiply to the other:

(4 , 6) = (x * 2, 3 * 2) = (2x , 6)

Simplify. Isolate the variable x. Divide:

(4) = (2x)

(4)/2 = (2x)/2

x = 4/2

x = 2

x = 2 is your answer.
