Hey, guys how to convert dates?

Answer:

121,6

Step-by-step explanation:

Since the only difference between the triangles are the letters and a few missing numbers, just replace the letters to get your answer. A and D are the same B and E are the same and C and F are the same. So the measurement of angle A is 121 degrees and the length of AB is 6

Answer:

8

Step-by-step explanation:

So the y-intercept is not given by your table because there is no x that is listed as 0.

But don't fret; we can still find it.

Let's see if the function is linear by seeing if we have the same slope per two points in the table.

For the first pair ( the points (-2,16) and (1,4) ), x increased by 3 and the y decreased by 12 so the slope there is -12/3=-4.

Now looking at the next pair ( the points (1,4) and (2,0) ), x increased by 1 while y decreased by 4 so the slope is -4/1=-4.

So the function appears to be linear.

So the slope-intercept form of a line is y=mx+b where m is slope and b is y-intercept.

We already found the slope from earlier which is m=-4.

So the equation so far is y=-4x+b.

Now to find b, the y-intercept, we need to use a point (x,y) on the line along with y=-4x+b.

Let's see my favorite on the list of points is (2,0).

y=-4x+b with (x,y)=(2,0)

0=-4(2)+b

0=-8+b

8=b

So the y-intercept is 8.

Answer:

Option D. Slope is 1 if the line is vertical

Step-by-step explanation:

we have

Part A)  Slope is a measure of the steepness of the line

The statement is true

Because, the steepness of a line is measured by the absolute value of the slope.

Part B) Slope is the ratio of vertical change to horizontal change

The statement is true

Because the formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

so

Is the ratio of vertical change to horizontal change

Part C) Slope is zero if the line is horizontal

The statement is true

Because If the line is horizontal, the y-coordinate of two points is the same

therefore

The vertical change is equal to zero

Part D) Slope is 1 if the line is vertical

The statement is Not true

Because, if the line is vertical the slope is undefined

Answer:

Slope is 1

1

if the line is vertical.

Answer:

Step-by-step explanation:

[tex]V_p = b \cdot h \cdot w[/tex], where b, h, w are base, height and width respectively.

[tex]V_{sp} = \frac{1}{3} \cdot {A_b} \cdot h[/tex], where h is the height, and A_b is the area of the base.

First let's calculate the volume of the paralelipiped by the first formula.

[tex]V_p = 7 \cdot 4 \cdot 3 = 84 in^2[/tex]

Then let's find out the height of the pyramid, which is 12 - 4 = 8 in.(See drawing)

Then the area of the base of the square pyramid is simply.

[tex]A_r = 3 \cdot 7 = 21 in^2[/tex]

Now we can find the volume of the pyramid.

[tex]V_{sp} = \frac{1}{3} \cdot 21 \cdot 8 = 56 in^3[/tex]

To find the total volume, let's add both volumes.

[tex]V_T = 84 + 56 = 140 in^3[/tex]

The volume of the composite figure is calculated by adding the volume of the individual shapes that make up the figure. For a figure composed of a rectangular prism and a triangular prism, you would calculate both volumes separately and add them together, giving a total volume of 186 in³ based on the dimensions provided.

In mathematics, the term volume refers to the amount of space occupied by a 3-dimensional object.

The composite figure you've given seems to include a rectangular prism and an extruded triangle (or possibly a rectangular prism attached to a triangular prism, without information about the orientation of the shapes, we cannot be certain).

For example, if it were a rectangular prism attached to a triangular prism, we would find the volume of both separately and then add them together. The volume of the rectangular prism would be found by length*width*height (12 in*4 in*3 in=144 in³). The volume of triangular prism would be 1/2*base*height*length (1/2*4 in*3 in*7 in = 42 in³). Adding them together, the volume of the composite figure would be 186 in³.

Answer:

x=7

Step-by-step explanation:

7(x-3) = 28

Distributive property

7x-21 = 28

Addition property of equality

7x = 49

Division property of equality

7x/7 = 49/7

x = 7

The value of x is 7 ..

Answer:

7

Step-by-step explanation:

Answer:

Here, the given function,

[tex]f(x) = -x^3 + 3x^2 + x - 3[/tex]

Since, the leading coefficient is negative, and degree is odd,

Thus, the end behaviour of the function is,

[tex]f(x)\rightarrow \infty\text{ as }x\rightarrow -\infty[/tex]

[tex]f(x)\rightarrow -\infty\text{ as }x\rightarrow \infty[/tex]

Therefore, the graph rises to the left and falls to the right.

Now, when f(x) = 0

[tex]-x^3+3x^2+x-3=0[/tex]

[tex]\implies -(x-3)(x-1)(x+1)=0[/tex]

[tex]\implies x=3, 1, -1[/tex]

That is, graph intercepts the x-axis at (3, 0), (1, 0) and (-1, 0).

When x = 0,

[tex]f(x) = - 3[/tex]

That is, graph intersects the y-axis at ( 0, -3),

Also, for 0 > x > -1 , f(x) is decreasing,

For 2.55 > x > 0, f(x) is increasing,

For 3 > x > 2.55, f(x) is decreasing,

Hence, by the above explanation we can plot the graph of the function ( shown below )

Answer:

parallel

Step-by-step explanation:

If you have two lines and a transversal that form corresponding angles that are congruent. Then the alternate interior angles are congruent and the same-side interior (some people call these consecutive angles) are supplementary.

This has to deal with Parallel Lines Theorem or the Converse of Parallel Lines Theorem.

The lines would be parallel.

Two lines will be parallel.

When two lines are cut by a transversal then the angles formed relatively same position in their respective line at the intersection transversal and two lines are called corresponding angles.

What is converse of corresponding angles theorem?

Converse of corresponding angles theorem states that When two lines are cut by a transversal and the formed corresponding angles are congruent then the two lines will be parallel.

Here given that two lines and transversal are forming corresponding angles which are congruent. So by converse of corresponding angles theorem, the two lines will be parallel to each other.

Therefore two lines will be parallel.

Answer:

y = -1/2 x +5

10 weeks

Step-by-step explanation:

The y intercept is 5  ( That is is the point where x=0)

Our slope is rise over run  or 1 lb /2 weeks

We know this is negative because the cat is losing the weight

slope = -1/2

The equation in slope intercept form is

y= mx + b where m is the slope and b is the y intercept

y = -1/2 x +5

We need to determine when y=0 to find when the cat loses all 5 lbs

0 = -1/2 x +5

Subtract 5 from each side

0-5 = -1/2x +5-5

-5 = -1/2x

Multiply each side by -2 to get x alone

-5 *-2 = -1/2x * -2

10 = x

It will take 10 weeks

Answer:

y = -1/2x + 5

It will take 10 weeks for the cat to lose 5 pounds.

Step-by-step explanation:

Find slope

Take 2 points (2,4) (6,2)

slope = -1/2

y-intercept

(0,5)

y = mx + b form

m represents slope

b represents y-intercept

y = -1/2x + 5

Find the number of weeks it will the cat to lose 5 pounds

Set y = to 0, to find when the cat loses weight

0 = -1/2x + 5

Subtract 5 in both sides

-5 = -1/2x

Isolate the variable by getting rid of the denominator

-1/2x * 2 = -x

2 * - 5 = -10

Simplify

-x = -10

Divide both sides by -1

-x/-1 = x

-10/-1 = 10

Simplify

x = 10

Final answer:

The total amount of money Peter and Angad won and shared in the ratio 6:1, with Peter getting £30 more than Angad, is £72.

Explanation:

Peter and Angad win some money and share it in the ratio of 6:1. If Peter gets £30 more than Angad, to find out how much they got altogether, we can use this ratio to express their winnings in terms of algebra. Let the amount Angad gets be x. Then Peter gets x+£30 since he gets £30 more than Angad. According to the ratio 6:1, Peter's share would be 6 times Angad's share; this gives us the equation 6x = x+ £30.

To solve for x, combine like terms: 6x - x = £30, which simplifies to 5x = £30. Divide both sides by 5 to find x: x = £6. Now that we know Angad receives £6, we can find Peter's share by multiplying Angad's share by 6: 6*£6 = £36. Add the £30 difference to get Peter's total: £36+£30 = £66.

To find the total amount they got altogether, add Angad's share and Peter's share together: £66 + £6 = £72.

6(4)=24

Step-by-step explanation:

The formula of a volume of a pyramid:

[tex]V=\dfrac{1}{3}BH[/tex]

B - base area

H - height

H - height of pyramids

Pyramid A:

[tex]B=(10)(2)=200\ m^2[/tex]

[tex]V_A=\dfrac{1}{3}(200)H=\dfrac{200}{3}H\ m^3[/tex]

Pyramid B:

[tex]B=10^2=100\ m^2[/tex]

[tex]V_B=\dfraC{1}{3}(100)H=\dfrac{100}{3}H\ m^3[/tex]

[tex]V_A>V_B\\\\V_A=2V_B[/tex]

The volume of the pyramid A is twice as large as the volume of the pyramid B.

The new height of pyramid B: 2H

The new volume:

[tex]V_{B'}=\dfrac{1}{3}(100)(2H)=\dfrac{200}{3}H\ m^3[/tex]

The volume of the pyramid A is equal to the volume of the pyramid B.

To compare the volumes of the two pyramids, we first need to calculate the volume of each pyramid using the formula for the volume of a pyramid:
\[ V = \frac{1}{3}Bh \]
where \( V \) is the volume, \( B \) is the area of the base, and \( h \) is the height.
First, let's calculate the volume of pyramid A:
\[ \text{Area of base of pyramid A} = \text{length} \times \text{width} = 10 \, \text{meters} \times 20 \, \text{meters} = 200 \, \text{square meters} \]
Now, let's call the height of pyramid A (and originally pyramid B) \( h \). Then, the volume of pyramid A is:
\[ V_{\text{A}} = \frac{1}{3} \times 200 \, \text{m}^2 \times h = \frac{200h}{3} \, \text{cubic meters} \]
Next, let's calculate the volume of pyramid B with its original height \( h \):
\[ \text{Area of base of pyramid B} = \text{side} \times \text{side} = 10 \, \text{meters} \times 10 \, \text{meters} = 100 \, \text{square meters} \]
So the original volume of pyramid B is:
\[ V_{\text{B}} = \frac{1}{3} \times 100 \, \text{m}^2 \times h = \frac{100h}{3} \, \text{cubic meters} \]
Now we can compare the volumes of pyramid A and the original volume of pyramid B:
\[ \frac{V_{\text{A}}}{V_{\text{B}}} = \frac{\frac{200h}{3}}{\frac{100h}{3}} = \frac{200}{100} = 2 \]
So, pyramid A has twice the volume of pyramid B.
Now, if the height of pyramid B increases to twice that of pyramid A, its new height is \( 2h \). Therefore, the new volume of pyramid B is:
\[ V_{\text{B new}} = \frac{1}{3} \times 100 \, \text{m}^2 \times 2h = \frac{200h}{3} \, \text{cubic meters} \]
Comparing this new volume of pyramid B to the volume of pyramid A:
\[ \frac{V_{\text{B new}}}{V_{\text{A}}} = \frac{\frac{200h}{3}}{\frac{200h}{3}} = 1 \]
So, the new volume of pyramid B is equal to the volume of pyramid A.
In summary, the volume of pyramid A is twice the volume of pyramid B when their heights are the same. If the height of pyramid B increases to twice that of pyramid A, the new volume of pyramid B is equal to the volume of pyramid A.

Answer:

x = 35

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 base angles from 180 for angle at vertex

vertex = 180° - (73 + 51)° = 180° - 124° = 56°

The vertex angle is composed of x and 21, so

x + 21 = 56 ( subtract 21 from both sides )

58 m^2.

Step-by-step explanation:

The  area of one of the 5 triangles is:

1/2 * 5.8 * 4 = 11.6 m^2

So the area of the pentagon

= 5 + 11.6

= 58 m^2

Answer:

The area is 58 meters squared.

Step-by-step explanation:

Since the pentagon is conveniently split into 5 separate but equal triangles, we only need to find the area of 1 triangle to find the rest. The area of triangles, as I'm sure you know, is 1/2bh. Using this equation, we get (1/2)x4x5.8. This equals 11.6. This is the area of one of the triangles. There are 5 triangles, so we multiply the area of 1 triangle by 5. 11.6x5= 58 meters squared.

Answer:

$4.75 is how much money is left over

Step-by-step explanation:

3* 1.25= 3.75

2* 2.50= 5.00

1* 6.50+ 6.50

5.00+3.75+6.50= 15.25

20- 15.25= 4.75

Final answer:

Nat spent a total of $15.25 on colas, hot dogs, and a hamburger. After paying with a $20 bill, he has $4.75 left.

Explanation:

To calculate how much money Nat has left after his purchases, we will add up the cost of the items he bought and subtract that total from the $20 bill he used for payment.

Cost of 3 colas: 3 × $1.25 each = $3.75

Cost of 2 hot-dogs: 2 × $2.50 each = $5.00

Cost of 1 hamburger: $6.50

Now we'll sum these amounts to find the total spending:

Total spending = $3.75 + $5.00 + $6.50 = $15.25

Next, we subtract the total spending from the $20 bill:

Change = $20.00 - $15.25 = $4.75

Therefore, Nat has $4.75 left after his purchase.

Answer:

x = 10

Step-by-step explanation:

Given the 2 equations

x - y = 11 → (1)

2x + y = 19 → (2)

Adding the 2 equations term by term eliminates the term in y, that is

(x + 2x) + (- y + y) = (11 + 19), simplifying gives

3x = 30 ( divide both sides by 3 )

x = 10

Answer:

x = 10

Step-by-step explanation:

We know that Rodney is given the following two linear equations and we are to find the value of x at which he would get a solution for this system of linear equations:

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

[tex] 2 x + y = 1 9 [/tex] - (2)

From (1):

[tex]x=11+y[/tex]

Substituting this value of x in (2):

[tex]2(11+y)+y=19[/tex]

[tex]22+2y+y=19[/tex]

[tex]3y=19-22[/tex]

[tex]y=-\frac{3}{3}[/tex]

[tex]y=-1[/tex]

Substituting this value of y in (1) to find x:

[tex]x=11+(-1)[/tex]

x = 10

The answer is:

[tex]3x^{2} -14x+7[/tex]

To solve the problem we need to add/subtract like terms. We need to remember that like terms are the terms that share the same variable and the same exponent.

For example, we have:

[tex]x^{2} +2x+3x=x^{2} +(2x+3x)=x^{2}+5x[/tex]

We have that we were able to add just the terms that were sharing the same variable and exponenr (x for this case).

So, we are given the expression:

[tex]5x^2-5x+1-(2x^2+9x-6)=5x^{2}-2x^{2}-5x-9x+1-(-6)\\\\(5x^{2}-2x^{2})+(-5x-9x)+(1-(-6))=3x^{2}-14x+7[/tex]

Hence, the answer is:

[tex]3x^{2} -14x+7[/tex]

Answer: [tex]\frac{41}{20}[/tex]

Step-by-step explanation:

The first step is to make the division of the fractions [tex]\frac{9}{16}[/tex] and

[tex]\frac{1}{4}[/tex]. To do this, you can flip the fraction [tex]\frac{1}{4}[/tex] over and multiply the numerators and the denominators of the fractions. Then:

[tex](\frac{\frac{9}{16}}{\frac{1}{4}})-\frac{1}{5}=(\frac{9}{16}*4)-\frac{1}{5}=\frac{36}{16}-\frac{1}{5}[/tex]

Reduce the fraction [tex]\frac{36}{16}[/tex]:

 [tex]=\frac{9}{4}-\frac{1}{5}[/tex]

Now you can make the subtraction:  in this case the Least Common Denominator (LCD) will be the multiplication of the denominators.   Divide each denominator by the LCD and multiply this quotient by the corresponding numerator and then subtract the products. Therefore you get:

[tex]=\frac{45-4}{20}=\frac{41}{20}[/tex]
