The table shows the amounts of two ingredients Tara used to make a snack mix. She ate 5/8 cup of the snack mix for lunch. How much of the mix is left? Show how you solved.

Answers

5/8 are eaten

So if you do 8/8 - 5/8 you get 3/8

In this exercise we have to use the knowledge of division, that is, how much is left of a certain food that is found in terms of fraction, in this way we can say that:

[tex]3/8[/tex] left.

So to calculate this exercise, we have to use the total amount minus the amount eaten to find what's left, so we have to:

For the figures shown, HJKL ~ QRST . The scale factor applied to HJKL to create QRST is 8 to 7. What is RS? A. 74 B. 72 C. 64 D. 49

Answers

The length of RS is 64 units. Therefore, the correct answer is C. 64.

Since HJKL is similar to QRST, corresponding sides of the two figures are proportional.

Given that the scale factor applied to HJKL to create QRST is 8 to 7, this means that the ratio of corresponding sides of HJKL to QRST is 8:7.

Let's denote the length of RS as x.

According to the scale factor, the ratio of corresponding sides RS and HJ is 8:7. So, we can set up the following proportion:

[tex]\[\frac{RS}{HJ} = \frac{8}{7}\][/tex]

Given that HJ is 56 units (since 8 times the length of HJ), we can solve for RS:

[tex]\[x = \frac{8}{7} \times 56\][/tex]

[tex]\[x = \frac{448}{7}\][/tex]

[tex]\[x = 64\][/tex]

Therefore, RS is 64 units.

So, the correct answer is C. 64.

Kim paycheck was $257.20. She put 1/4 of her paycheck into a savings account and used 1/3 of what was left to pay bills. How much money does she have remaining from her paycheck

Answers

Hello!

Let's divide Kim's paycheck by 4 to calculate how much she put in her savings account, and then subtract that from the paycheck.

257.20 ÷ 4 = 64.30

257.20 - 64.30 = 192.9

Now, divide this by 3 and then subtract the money she used to pay her bills to find how much money Kim has left.

192.9 ÷ 3 = 64.30

192.9 - 64.30 = 128.6

In parallelogram ABCD, m∠A = 24°. What are the measures of angles B, C, and D? Justify. please help

Answers

parallelogram has 2 pairs of angles as well as a sum angle of 360
therefore, another angle is also 24°and the other two are 360-24*2=312. 312/2=156

four angles are 24,24,156,156
The sum of the angles in a parallelogram is 360°. 

a+b+c+d=360°

The opposite angles in the parallelogram are congruent.

a=c

b=d

So if a=24°... and we know a=c, then c=24°.

a=24

c=24

b=?

d=?

a+b+c+d=360°
plug in the data we know
24+b+24+d=360
48+b+d=360
b+d=312

If b+d=312, and we know that they are congruent, then to find their values just divide 312 by 2

312/2=156°

b=156°

d=156°

the resultant vector is <0,0>


6] The value of x will be found as follows
tan θ=(opposite)/(adjacent)
θ=20°
hence:
tan 20=x/15
x=15tan20
x=5.4595~5.5 yd


Question 5.
To get the resultant of two vectors we add the two vectors given. 
In this case, <-6,5> and <6,-5> 
Therefore, <(-6+6), (5+-5)>
                  = <0,0>

Question 6
The appropriate trigonometric ratio to use in the question is tan
Tan θ = opposite/ adjacent
θ is 70 degrees ( 90-20)
Opposite is 15 yd 
Adjacent is x
Therefore;
               Tan 70 = 15/x
                        x = 15/tan 70
                        x = 5.45955
                          ≈ 5.5 yd
Thus, the value of x (nearest tenth) is 5.5 yd

Well, 3/6 = 8/?

Answers

16 will go where the question mark is located

So 3/6 = 8/16

Think of it like this: if you had three slices of pizza out of 6 total, then you had half the pizza. The same goes for if you had 8 slices out of 16 total

You can use the cross multiplication rule to find x
3/6 = 8/x
3*x = 6*8
3x = 48
3x/3 = 48/3
x = 16
remember, you can do anything to an equation as long as you do it to both sides


3/6=8/?
multiply both sides by ?
3?/6=8
mulitly both sides by 6
3?=(6)(8)
3?=48
divide both sides by 3
?=16

Use the parabola tool to graph the quadratic function f(x)=−12x2+7. Graph the parabola by first plotting its vertex and then plotting a second point on the parabola.

Answers

First we find the vertex of parabola [tex]f(x)=-12 x^{2} +7[/tex]

The vertex of parabola is [tex]( \frac{-b}{2a},f( \frac{-b}{2a})) [/tex]
Here,
b = coefficient of x term
a = coefficient of x² term

For given parabola, b = 0 , a = -12

So,
[tex] \frac{-b}{2a}= \frac{0}{-24} =0 [/tex]

And,

[tex]f( \frac{-b}{2a} )=f(0) = -12(0)+7=7[/tex]

Thus the vertex of parabola is (0, 7)

To find another point on parabola, substitute x by 1.

[tex]f(1)=-12( 1^{2}) +7=-12+7=-5[/tex]

So the second point on parabola is (1,-5)

Tell whether the statement below is always, sometimes, or never true. Equation like, a + 4 = 8 and 4 - m = 2 have exactly one solution.

Answers

a + 4 = 8

a = 4

Can you add anything else to 4 to get 8? No.

4 - m = 2

-m = -2

m = 2

Can you subtract anything besides 2 from 4 to get 2? No.

So the statements are always true.

Final answer:

The statement that equations 'a + 4 = 8' and '4 - m = 2' have exactly one solution is always true, as these are linear equations with one variable. Such equations normally have a unique solution when they are not degenerate.

Explanation:

The statement 'Equations like a + 4 = 8 and 4 - m = 2 have exactly one solution' is always true. For the equation a + 4 = 8, there exists one and only one number a such that when you add 4 to it, you get 8.

Similarly, for 4 - m = 2, there is exactly one solution for m that makes the equation true. These are examples of linear equations with one variable, which have a unique solution assuming they are not degenerate (such as an equation like 0x = 0 which has infinitely many solutions).

In general, if a and b are two given numbers, there exists one and only one number x, and also one and only one number y, such that a+x=b, and y+ a = b respectively.

This principle follows from the property of numbers where there exists a definite number, called 0, such that for every number a, we have a + 0 = a and 0 + a = a. Equations are statements of truth, like √4=±2 which indicates a solution set of {-2, 2} for the equation x² = 4.

a person walking along a straight road observes that at two consecutive kilometer stones, the angles of elevation of a hill in front of him are 30degree and 45 degree find the height of the hill

Answers

First, you need to draw the situation: you have three points on a straight line, A is the first kilometer stone, B is the second one and C is the foot of the hill. Let's call H the top of the hill. Connecting H with both A and B you get two triangles rectangle (BCH and ACH).

The triangle rectangle BCH has one other angle that is 45°, which means that it is an isosceles triangle, therefore BC = HC = height of the hill (h).

Now, consider the triangle ACH: it has an angle of 30° (which means that the other angle is 60°) and AC = BC + AB = h + 1 (where we considered h measured in km).
In such a particular triangle (30°- 60°- 90°), the ratio between the long and the short leg is √3, which means that:
√3·HC = AC

We can then write:
√3·h = (h + 1)

which can be solve for h:
√3·h - h = 1
h(√3 - 1) = 1
h =1/ (√3 - 1) 

We can rationalize:
h =  [tex] \frac{1}{ \sqrt{3} - 1} \frac{ \sqrt{3} + 1}{ \sqrt{3} + 1 } [/tex]
   = (√3 + 1) / 2
   = 1.366 km

Therefore the correct answer is: the hill is 1.366km high

solve the equation for x 6x + 1 - 4x = 2+ x + 4

Answers

first simplify all of the numbers with common variables (or those without)

6x - 4x + 1 = 2 + x + 4

2x + 1 = x + 6

subtract x from both sides to move x to one side

2x (-x) + 1 = x (-x) + 6

x + 1 = 6

subtract 1 from both sides to isolate the x

x + 1 (-1) = 6 (-1)

x = 6 - 1

x = 5

5 is your answer for x

explain how you can find a fraction that is equivalent to 1/4

Answers

Hi there!

If you wanted to find a number that is equal to a fraction, we can either 1. simplify, or 2. multiply both the numerator and the denominator by the same number. 

Since 1/4 is already at its simplest form, we can multiply both the numerator and the denominator by any number. Let's do 4:

1 * 4 = 4
4 * 4 = 16

So, 4/16 would be an equivalent fraction.

The sum of digits in a two-digit number is 14. If you double the reversed number and add the result to the original number, the sum would be 222. Find the original number.

Answers

Final answer:

The original two-digit number is 86. We determined this through solving a system of equations where the sum of the digits is 14 and doubling the reversed number before adding it to the original number equals 222.

Explanation:

The student is given a mathematical problem involving a two-digit number. First, we are told that the sum of the digits of the number is 14. Let's assume that the number is made up of digits a and b, where a is the tens digit and b is the ones digit. Therefore, our number can be represented as 10a + b and the reversed number as 10b + a.

According to the given information:

a + b = 14 (the sum of the digits)(2 × (10b + a)) + (10a + b) = 222 (double the reversed number added to the original gives 222)

Writing the second equation in standard form gives us 20b + 2a + 10a + b = 222, which simplifies to 21b + 12a = 222. Using the first equation, we can substitute the value of b as (14 - a) into the second equation, resulting in 21(14 - a) + 12a = 222. Solving for 'a' gives us a value of 8, and consequently, b equals 6. Therefore, the original number is 86.

Final answer:

The original number is 86.

Explanation:

To find the original number, let's assume the tens digit as 'x' and the units digit as 'y'. So, the original number can be written as 10x + y.

According to the question, we have two equations:

Equation 1: x + y = 14 (The sum of digits is 14)

Equation 2: (10y + x) + 2(10x + y) = 222 (Double the reversed number and add it to the original number is 222)

Simplifying Equation 2, we get: 12x + 21y = 222

We can now solve the system of equations by substituting the value of 'x' from Equation 1 into Equation 2:

12(14 - y) + 21y = 222

Simplifying further, we get:

168 - 12y + 21y = 222

Combining the 'y' terms, we get:

9y = 54

Dividing both sides by 9, we get:

y = 6

Substituting the value of 'y' into Equation 1, we get:

x + 6 = 14

Subtracting 6 from both sides, we get:

x = 8

Therefore, the original number is 10x + y = 10(8) + 6 = 86.

1st equation: 5x + 60y =35

2nd equation: x + y = 1.5 r
3rd equation: rewrite 2nd equation as : x =1.5-y)

replace x in first equation with 3rd equation:

5(1.5-y) + 60y = 35

 now solve for y:
7.5 - 5y + 60y = 35
7.5 + 55y = 35
55y = 27.5
y = 27.5 / 55 = 0.5
 

now replace Y with 0.5 in the 2nd equation and solve for x

x +0.5 = 1.5

x = 1.5-0.5
x = 1

5x = 5(1) = 5 miles walked

5X + 60Y = 35
X + Y = 1.5
Ok so this is known as a system of equations. The x variable in the first equation is the same as the x in the second equation, as is the y.
So in order to solve this, let's solve for one of the variables in the second equation. It doesn't matter which so lets just pick the variable y.
So
X + Y = 1.5
Subtract X from both sides
Y = -X + 1.5
Voila! You have a variable for y. Now you can substitute you value of y into the other equation.
5X + 60(-X + 1.5) = 35
Now do you see how we only have one variable to solve for in the equation? Solve this equation and you have the value of x.
5X - 60X + 90 = 35
-55X = -55
X = 1
Hah! We have a value for X! But what is the value of y? In ordering to find the value of y you need to take a previous equation and substitute the value that we found for x into the equation. Let's take the easiest equation shall we?
X + Y = 1.5
X = 1
1 + Y = 1.5
Y = 0.5
And there we are! The values we were in search of across the dry deserts and cold, salty waters. Eww salty water. What was I talking about? Sorry I'm ADHD.

A bicyclist started on his trip from city A to city B. In 1 hour and 36 minutes, a biker also left A and headed towards B, and he arrived there at the same time as the bicyclist. Find the speed of the bicyclist if it is less than the speed of the biker by 32 km/hour, and the distance between the two cities is 52 km.

Answers

Speed of first bicyclist=x
Speed of  biker= x+32

1+36/60 = 1.6 hours
Bicyclist time is 1.6 hours longer than biker.
Equation is:
52/x - 1.6 = 52/(x+32)
Solve for x.
52(x+32)-1.6(x+32)=52x
5x+1664-1.6x²-51.2x=52x
Simplify
1.6x²+51.2x-1664=0
Using quadratic formula.
We get
x=20 km per hour which is the speed of the Bicyclist.
Now speed of  biker= 20+32=52 km/hr
