The percent of 32% of her daily amount of fiber, she has at breakfast.

The numerical relationship between two values that demonstrates how frequently one value contains or is contained within another.

Given:

Keesha keeps track of the fiber she eats to make sure she gets enough each day.

Her breakfast contains 8 grams of fiber, and her recommended daily amount is 25 grams per day.

Keesha wants to know what percent of her daily amount of fiber she has at breakfast.

The table to show an equivalent ratio where the total amount is 100 grams.

Let n be the required value.

That means,

8/25 = n/100

n = 800/25

n = 32

Therefore, her daily amount of fiber is 32%.

x + 2y = 7

3x - 2y = -3

Adding the 2 equations will eliminate y:

4x  = 4

x = 4/4

x = 1

Plug x = 1 into the first equation:

1 + 2y = 7

2y = 6

y = 3.

Answer:

j + m

jm

[tex]\frac{j}{m}[/tex]

Step-by-step explanation:

We have j and m and are asked to add, multiply and divide them both.

When it comes to adding, its all about like terms, if the terms are not alike meaning ending in the same variable they cannot be added.

Therefore j + m is equal to just j + m.

Now for multiplying, this is free rule, you can freely multiply any variable you want without reprecussion.

Therefore, j * m is equal to jm.

Now for dividing, this works like adding, where you can divide only if the terms are the same, since j and m are not the same. J divided by M is equal to [tex]\frac{j}{m}[/tex]

Answer:  (a + 2)(a - 2)  which is the first answer choice

=========================================================

Explanation:

Use the difference of squares factoring rule which is x^2 - y^2 = (x+y)(x-y)

In this case, x = a and y = 2

x^2 - y^2 = (x+y)(x-y)

a^2 - 2^2 = (a+2)(a-2)

a^2 - 4 = (a+2)(a-2)

Answer:

Let's call the first studio, yoga studio A.

Let's call the second studio, yoga studio B.

The equations:

Yoga Studio A: y=10x+55

Yoga Studio B: y=12.5x+25

So, for 12 classes:

Yoga Studio A: y=10(12)+55, y=175

Yoga Studio B: y=12.5(12)+25, y=175

These two numbers are equal, so Griffin is right.

For 10 classes:

Yoga Studio A: y=10(10)+55, y=155

Yoga Studio B: y=12.5(10)+25, y=150.

These two numbers are not equal, so Gigi is wrong.

The answer is C.

Step-by-step explanation:

You should plug the numbers into the quadratic formula to get the answer.

Answer:

A:  -5 ± √ 17 / 2

Step-by-step explanation:

Consider the following equations:

ax^2 + bx + c - This is an equation you use in understanding quadratic functions.

x= (−b± √b^2−4ac) / 2a - This is the quadratic formula used to solve quadratic functions

So:  ax^2 + bx + c = x^2 + 5x + 2

SOLVE:

-(5) ± √ 5^2−4(1)(2)) / 2(1)

= -5 ± √ 25− 8 / 2

= -5 ± √ 25− 8 / 2

= -5 ± √ 17 / 2

Answer:

323.5 square inches

Step-by-step explanation:

The cereal box is not shown. However, the given details are enough to arrive at a solution

[tex]Length = 13.5in[/tex]

[tex]Width = 2.5in[/tex]

[tex]Height = 8in[/tex]

Required

This is calculated as:

[tex]TSA = 2 * (Length * Width + Length * Height + Width * Height)[/tex]

[tex]TSA = 2 * (13.5 * 2.5 + 13.5 * 8 + 2.5 * 8)[/tex]

You are right because the -4 and 4 would be an x - intercept but it's not there on the answer choice. So, go with A. 0 Another explainationor this is (0,9) is the vertex, and the x intercept lies on 0.

2x + 3 - 4 = 5x - 7

=> 2x + 3 - 4 + 7 = 5x

=> 3 - 4 + 7 = 5x - 2x

=> 3 - 4 + 7 = 3x

=> -1 + 7 = 3x

=> 6 = 3x

=> 6/3 = x

=> 2 = x

Step-by-step explanation:

Answer:

let marked price = x

on 10% discount, price= x-10%of x

=x-(10x/100)

=x-(x/10)

=9x/10

on further 10% discount, total discount = 10% of 9x/10

=10/100 * 9x/10

= 9x/100

= 9%of x

hence, the single discount given on marked price is 9%
