If the width and length of a rectangle are both increased by 10%, by what percent does the area of the rectangle increase?

By what percent does the perimeter of the rectangle increase?

Answer: -1 ≤ x ≤ 4.

Step-by-step explanation: To solve this problem, we first add 7 to the inequality: -4 ≤ 4x ≤ 16. Then we divide the entire equation by 4 to get -1 ≤ x ≤ 4.

Given:

There are 4 quarts in a gallon.

She wants to convert 6 quarts to a gallon.

To find:

Whether she should multiply 6 by 4 or divide 6 by 4 to find her answer.

Solution:

We have,

[tex]4\text{ quarts}=1\text{ gallon}[/tex]

[tex]1\text{ quarts}=\dfrac{1}{4}\text{ gallon}[/tex]

[tex]6\text{ quarts}=\dfrac{6}{4}\text{ gallon}[/tex]

Here, 6 quarts is equal to [tex]\dfrac{6}{4}[/tex] gallon. It means we need to multiply 6 by 4 in [tex]4\text{ quarts}=1\text{ gallon}[/tex] to find the answer.

Answer:

Step-by-step explanation:

Given Katiyln and lewis share sweets in the ratio =7:1

katliyn gets= 21 sweets

share of katiyln sweet =7x

share of Lewis sweet =X

So 7x=21 given

X=21/7

X=3

So Lewis gets x =3 sweets.

Answer:

1. f(n+1) = f(n) + 0.09

2. The correct answer is 403 = x. The student’s error is that she did not cancel out properly the constant by the inverse add ended to find the answer of the variable.

3. B

4. D 34 + 6(25.3)

Answer:

Step-by-step explanation:

16 = - 4y - 12

Bringing like terms on one side

16 + 12 = - 4y

28 = - 4y

28/-4 = y

-7 = y

Answer: DE is 15 and AB is 6

Step-by-step explanation:

Okay, so when two shapes are similar, that means they are proportional. Look at the sides. Notice how the lengths of each side on the larger triangle are all multiples of the lengths of the smaller triangle (side CE, for example, is 24, and AC is 8 since 24 is 3 times larger than 8, you know that particular side was dilated by 3x).

Since these are similar, but not congruent, you know that the dilation was applied to the entire shape equally. In other words, each side is dilated by 3 or is 300% larger.

So, to find DE, just multiply the corresponding side, BC, by 300%.

5*300% (or just 5*3) is 15. So, DE is 15cm long. Make sense?

For AB, you know the scale factor is 3, so you have to figure what number times 3 will get you 18. Because 6*3 is 18, you know AB has to be 6.

Answer:

-n^3 – 5n + 4

Step-by-step explanation:

f(n) = -n^3 – 4

g(n) =  -n +4

f(n)+ g(n) = (-n^3 – 4n)+(-n +4)

               = (-n^3 – 4n -n +4)

               = -n^3 – 5n +4

Answer:

m = 0.28571428571

or 0.29(to the nearest tenth)

Step-by-step explanation:

First, distribute

12(−1.4m+0.4)=

-16.8m + 4.8 =

Now move the constant to the right.

-16.8m + 4.8 =

-16.8m = -4.8 =

Now divide,

-16.8m = -4.8 =

m = 0.28 or 0.29

Answer:

(30, 0) and (0, 50)

Step-by-step explanation:

( 0 , y ) are coordinates of y-intercept.

( x , 0 ) are coordinates of x-intercept.

25x + 15y = 750

25(0) + 15y = 750 ⇒ y = 50

( 0 , 50 ) are coordinates of y-intercept.

25x + 15(0) = 750 ⇒ x = 30

( 30 , 0 ) are coordinates of x-intercept.

Answer:

the graph is of a cubic function.

Step-by-step explanation:

f(x)= x^3. It should have at least one zero

The graph shows cubic polynomial.

A polynomial is an equation that solely uses the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are also known as indeterminates.

Given:

In the graph the number of times the graph touches the x- axis it will have that many zeroes or solution for the polynomial.

The given graph touches the x-axis three times which shows the polynomial will have three solution and the degree of the polynomial is 3.

Hence, the graph shows cubic polynomial.

Answer:

red

Step-by-step explanation:

The complete question is as follows;

At a soccer tournament 12 teams are wearing red shirts, 6 teams are wearing blue shirts, 4 teams are wearing orange shirts, and 2 teams are wearing white shirts. For every 2 teams at the tournament, there is 1 team wearing ____ shirts

Solution;

The total number of teams we have is 12 + 6 + 4 + 2 = 24 teams

Now looking at the number of teams wearing red shirts , we can see 12 of them which is exactly half the total number of teams

So what this means is that for every two teams at the tournament, there is 1 team wearing red shirts

Answer:

50/2.80= 17

17 dounuts

Answer:

D. identity

Step-by-step explanation:

- 6a + 3 = - 3(2a - 1)

First, distribute -3 within the parenthesis.

- 6a + 3 = - 6a + 3

Subtract 3 from both sides of the equation

- 6a = - 6a

Divide - 6 on both sides of the equation

a = a

We know because both sides have the same equation, and that it is true, that this equation has infinite solutions, so the answer would be D. Identity

For those who don't know, identity in algebra means that the equation is true no matter what is substituted in for the variable. It will always be true.

I hope that this helps! :)
