Answer:

400

Step-by-step explanation:

All you have to do is multiply 20 by itself one time. You get 400.

So, 20^2 is 400.

30.8

you take 25^2 + 18^2 and find the square root of that which is 30.8 for this problem.

please give me brainliest :)

Answer:

Step-by-step explanation:

Speed is represented according to the equation;

Speed = Distance/Time

Given;

Distance d = 400km

Time t = 8 hours

From the formula

s = d/t

s = 400/8

s = 50

Substitute s = 50 back into the formula;

s = d/t

50 = d/t

d = 50t

This expression means that the speed is directly proportional to t where 50 is the constant of proportionality;

Hence the constant of proportionality for the relationship between distance in kilometers and number of hours is 50

Answer: Two constants of proportionality for this situation are 50 and 1/50. The relationship between these two values are that they are both reciprocals.

Step-by-step explanation:

One a piece of paper, graph f(x)= (0.4)^x. To determine which answer choice matches the graph you drew.

Answer: Graph B

The graph of a function f(x) = 6(0.4)× is shown in graph (B) because the domain of the function is all real numbers and the range of a function is f(x) > 0, the y-intercept of the function is (0, 6)

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

f(x) = 6(0.4)×

The domain of the function is all real numbers.

The range of the function:

f(x) > 0

Plug x = 0

y = 6

Thus, the graph of a function f(x) = 6(0.4)× is shown in graph (B) because the domain of the function is all real numbers and the range of a function is f(x) > 0, the y-intercept of the function is (0, 6)

Given:

Rachel used [tex]\dfrac{1}{3}[/tex] of her savings to buy brushes.

She used [tex]\dfrac{3}{5}[/tex] of her savings to buy paint.

To find:

The fraction for remaining savings.

Solution:

Fraction that Rachel used of her savings to buy brushes and paint is

[tex]\text{Fraction for used amount}=\dfrac{1}{3}+\dfrac{3}{5}[/tex]

                                    [tex]=\dfrac{5+9}{15}[/tex]

                                    [tex]=\dfrac{14}{15}[/tex]

Now,

[tex]\text{Fraction for remaining savings}=1-\text{Fraction for used amount}[/tex]

[tex]\text{Fraction for remaining savings}=1-\dfrac{14}{15}[/tex]

[tex]\text{Fraction for remaining savings}=\dfrac{1}{15}[/tex]

Therefore, [tex]\dfrac{1}{15}[/tex] of her savings is remaining.

Answer:

D. 64 trash cans

Step-by-step explanation:

The answer is D. because 1 * 16 = 16 so 4 * 16 = 64 trash cans.

Answer:

probably 64

think of 16=1

and 64 ÷ 16 is 4

Answer:

-3

Step-by-step explanation:

Let the unknown number be n

We are to write the expression as equation;

Six times a number plus 4 is the same as the number minus 11.

Six times a number is given as;

6n

Six times a number plus 4 is expressed as 6n+4

The unknown number minus 11 will be expressed as n-11

Finally If Six times a number plus 4 is the same as the number minus 11, them!

6n+4 = n-11

Next is to calculate n;

Collect like terms;

6n-n = -11-4

5n =-15

Divide through by5

5n/5 = -15/5

n = -3

Hence the vale n is -3

Answer:

Hi there,

Make Nick's age = x

Caroline's age = x + 12

Mark's age = x - 4

x + (x + 12) + (x - 4)

Remove brackets

x + x + 12 + x - 4 = 44

Collect like terms

3x = 44 - 12 + 4

3x = 36

x = 12

Answer:

Volume = 6048 [tex]in^{3}[/tex]

Step-by-step explanation:

Volume is the capacity of substance that a given measuring object can contain. It can be determined as;

Volume = length x width x height

In the given question, the refrigerator has an internal dimensions 18 inches, 14 inches and 24 inches.

The volume of the refrigerator can be determined as;

Volume = 24 x 14 x 18

            = 6048

Volume  = 6048 [tex]in^{3}[/tex]

Thus, the internal volume of the refrigerator is 6048 cubic inches.

Answer:

we will have to multiply the second equation by 3 to eliminate the y variable by adding.

Step-by-step explanation:

Given the equations

4x – 3y = 6              →   (1)

6x + 2y = 10             →   (2)

As the first equation is multiplied by 2,

2(4x – 3y) = (2)6

8x - 6y = 12               →  (3)

As we have to eliminate y,

so multiply the second equation by 3,

6x + 2y = 10

3(6x + 2y) = 3(10)

18x + 6y = 30              →  (4)

So now adding the new equations (3) and (4) will eliminate the y variable by adding

8x - 6y = 12

18x + 6y = 30

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

26x + 0y = 42

26x = 42

x = 42/26

x = 21/13

Therefore, we will have to multiply the second equation by 3 to eliminate the y variable by adding.

Answer:

a) When x = 3, both expressions have a value of 30. When x = 5, both expressions have a value of 42.

b) When x = 1, both expressions have a value of 18, and when x = 8, both expressions have a value of 60.

Step-by-step explanation:

Which best proves why the expressions 4 (x + 3) + 2 x and 6 (x + 2) must be equivalent expressions?

Mathematically this is expressed as:

4(x + 3) + 2x = 6(x + 2)

Verifying the options

a) When x = 3, both expressions have a value of 30. When x = 5, both expressions have a value of 42.

When x = 3

4(x + 3) + 2x = 6(x + 2)

4(3 + 3) + 2(3)= 6(3 + 2)

24 + 6 = 6(5)

30 = 30

When x = 5

4(x + 3) + 2x = 6(x + 2)

4(5 + 3) + 2(5)= 6(5 + 2)

4(8) + 10 = 6(7)

42 = 42

Statement in option a is correct

b) When x = 1, both expressions have a value of 18, and when x = 8, both expressions have a value of 60.

When x = 1

4(1 + 3) + 2x = 6(x + 2)

4(1 + 3) + 2(1)= 6(1 + 2)

4(4) + 2 = 6(3)

18 = 18

When x = 8

4(8 + 3) + 2x = 6(8 + 2)

4(11) + 2(8)= 6(8 + 2)

44 + 16 = 6(10)

60 = 60

Statement in option b is correct

c) When x = 2, both expressions have a value of 15, and when x = 6, both expressions have a value of 39.

When x = 2

4(x + 3) + 2x = 6(x + 2)

4( 2 + 3) + 2(2)= 6(2 + 2)

4(5)+ 4 = 6(4)

20 + 4 = 6(4)

24 = 24

4(x + 3) + 2x = 6(x + 2)

4(6 + 3) + 2(6)= 6(6 + 2)

4(9) + 12 = 6(8)

48 = 48

Statement in Option c is wrong

Hence, Statement in Option a and b is correct

Step-by-step explanation:

An open first syllable is one that has a vowel at its end and that vowel causes a long vowel sound at its end. Long vowel sounds are those sounds whose pronunciation is the same as those of the letters.

Among the words listed, fro-zen has a long vowel sound in the form of the o at the end of the first syllable. Thus it can be classified as having an open first syllable.

Complete question :

Ryan is choosing between two exercise routines. In Routine #1, he burns 22 calories walking. He then runs at a rate that burns 10.5 calories per minute. In Routine #2, he burns 39 calories walking. He then runs at a rate that burns 6.25 calories per minute. For what amounts of time spent running will Routine #1 burn at most as many calories as Routine #2?

Answer:

4 minutes

Step-by-step explanation:

Given the following exercise routines :

Routine #1,

Walking : burns 22 calories walking. He then running : burns 10.5 calories per minute.

Routine #2,

Walking : burns 39 calories walking. He then running : burns 6.25 calories per minute.

Let number of tone spent running = t

Hence,

Routine 1 ; calories burned

22 + 10.5t

Routine 2 ; calories burned

39 + 6.25t

Equating the two equations :

22 + 10.5t = 39 + 6.25t

10.5t - 6.25t = 39 - 22

4.25t = 17

t = 17/4.25

t = 4
