A worker is stacking boxes. One stack has boxes that are 2 inches high. The other stack has boxes that are 5 inches high. At what height will the two stacks of boxes be equal in height?

Answer:

70 m/s = 252 km/hr

1 m/s = 3.6 km/hr

Assuming Adams amount is x, three times his amount will be 3x. $14 more than the times Adam's amount will be 14 +3x.

Therefore if Arlene's money is $56 which is $14 more than three times Adam's amount, then the equation will be ;

14+3x=56

Answer: $13.44

Step-by-step explanation:

Inflation is causing the manufactured goods to rise at 2.3% per year. The price in 5 years can be calculated using compound interest formula:

= 12 * ( 1 + 2.3%)⁵

= ‭13.444956907696116‬

= $13.44

Answer:

It is because of the microgravity.

Step-by-step explanation:

Bread, Alcohol, Salt, Pepper, Soda, etc. cannot be eaten in space due to lack of gravity and microgravity.

Answer:

(- 3, 0 ), (4, 0 )

Step-by-step explanation:

To find the x- intercepts let f(x) = 0

[tex]\frac{x^2-x-12}{5x^2+ 4x}[/tex] = 0

The denominator cannot equal zero as this would make f(x) undefined.

Equate the numerator to zero and solve for x

x² - x - 12 = 0 ← in standard form

(x - 4)(x + 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

x + 3 = 0 ⇒ x = - 3

x- intercepts are (- 3, 0 ) and (4, 0 )

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

Explanation:

We have these three facts:

Those three facts allow us to use the AAS (angle angle side) congruence theorem to prove that triangle ABC is congruent to triangle EBD.

Then by CPCTC (corresponding parts of congruent triangles are congruent), we know that AC = DE. Note how 'A' and 'C' are the first and last letters of ABC; similarly, 'E' and 'D' are the first and last letters of EBD. Segment ED is the same as segment DE.

So to find the length of DE, we need to find the length of AC. To do that, we need the value of x.

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

Recall earlier that AB = BE. Use this to find x

AB = BE

1.5x = 3x-6

1.5x-3x = -6

-1.5x = -6

x = -6/(-1.5)

x = 4

Now we can find the length of AC

AC = x+3

AC = 4+3

AC = 7

This must mean DE = 7 as well.

Answer:

DE=7

Answer:

A

[tex] = \frac{78}{360} \\ = \frac{13}{60} [/tex]

B

[tex]let \: total \: number \: be \: x \\ \frac{13}{60} x = 1164 \\ x = \frac{1164 \times 60}{13} \\ x = 5372 \: movies[/tex]

C

A year has (4 × 12) weeks

= 48 weeks.

In 1 week = 9,568,000 movies

48 weeks = (48 × 9,568,000) movies

Average movies = 459.264 movies

D

Since 9.568 million movies are rented.

How about in one year ( 48 weeks )

Convert 1 year to weeks and compare with 1 week

Answer:

[tex]36[/tex]

Step-by-step explanation:

Given

[tex]x^2 - 12x = 21[/tex]

Required

Make a perfect square

First, get the coefficient (k) of x

[tex]k = -12[/tex]

Divide by 2

[tex]\frac{k}{2} = \frac{-12}{2}[/tex]

[tex]\frac{k}{2} = -6[/tex]

Square this result:

[tex](\frac{k}{2})^2 = (-6)^2[/tex]

[tex](\frac{k}{2})^2 = 36[/tex]

Hence, 36 when added to the left-hand side makes it a perfect square trinomial

Answer:

Step-by-step explanation:

To obtain the strongest mix :

Maria:

2 cups of concentrate ; 5 cups of water

Ratio = 2/5 = 0.4 concentrate per 1 cup of water

Laurie:

3 cups of concentrate ; 7 cups of water

Ratio = 3/7 = 0.4285714 concentrate per 1 cup of water

0.4285714 > 0.4

Hence, Laurie's mix is the strongest as it has higher concentrate per cup of water.

Answer:

2/5 of a Mile

Step-by-step explanation:

Total mikes from school to Steven house = 3/5 of a Mile

If Steven walked 2/3 of the way there, the distance he walked =2/3×3/5 = 2/5

If he stopped the rest, then the distance he travelled before stopping is 2/5 of a Mile

Answer:

90 + 72 -> 162

Step-by-step explanation:

15 times 6 equals 90 and 12 times 6 equals 72, the distributive property equation is 90 + 72 in which can be added to 162 as a result.

Hey there!

The formula is: a(b + c) = a(b) + a(c) = ab + ac

“6(15 + 12)”

6(15 + 12)

6(15) + 6(12)

6(15) = 90

6(12) = 72

NEW EQUATION: 90 + 72

ANSWER: 90 + 72 = 162 ☑️

Question:

Alex skateboards at a constant speed from his house to school 3.8 miles away. It takes him 18 minutes.

a. What fraction represents his constant speed, c?

b. After school, Alex skateboards at the same constant speed to his friend’s house. It takes him 10 minutes.  Write the fraction that represents constant speed, c, if he travels a distance of y.

c. Write the fractions from parts(a) and (b) as a proportion, and solve to find out how many miles Alex’s  friend’s house is from school. Round your answer to the tenths place.

Answer:

(a) [tex]c = \frac{3.8}{18}[/tex]

(b) [tex]c = \frac{y}{10}[/tex]

(c) 2.1 miles

Step-by-step explanation:

Solving (a):

Given

[tex]Distance = 3.8\ miles[/tex]

[tex]Time = 18\ minutes[/tex]

Required

Determine the constant speed, c.

Speed is calculated as:

[tex]Speed = \frac{Distance}{Time}[/tex]

So, we have:

[tex]c = \frac{3.8}{18}[/tex]

Solving (b):

Given

[tex]Distance = y[/tex]

[tex]Time = 10\ minutes[/tex]

Required

Determine the constant speed, c.

Speed is calculated as:

[tex]Speed = \frac{Distance}{Time}[/tex]

So, we have:

[tex]c = \frac{y}{10}[/tex]

Solving (c): Write (a) and (b) as proportions and solve for y.

As a proportion, we have

[tex]\frac{y}{10} = \frac{3.8}{18}[/tex]

Multiply both sides by 10

[tex]10 * \frac{y}{10} = 10 * \frac{3.8}{18}[/tex]

[tex]y = 10 * \frac{3.8}{18}[/tex]

[tex]y = \frac{38}{18}[/tex]

[tex]y = 2.11111[/tex]

[tex]y = 2.1\ miles[/tex]  ---- approximated

Answer:

[tex]12 * (2 - 3) + (4 * 2)[/tex]

Step-by-step explanation:

Follow PEMDAS for the given answer.

PEMDAS is the order of operation, and is:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction.

Reverse solve the answer so that the result is the question.

First, solve the parenthesis:

12 * (2 - 3) + (4 * 2)

12 * (-1) + 8

Next, multiply 12 and -1 together:

12 * -1 = -12

Finally, add:

-12 + 8 = -4

12 * (2 - 3) + (4 * 2) is your answer.

~

[tex]12 \times (2 - 3) + (4 \times 2)[/tex]

Step-by-step explanation:

Add parentheses to the following equation to make it true.

[tex]12 \times 2 - 3 + 4 \times 2 = - 4[/tex]

[tex] = 12 \times 2 - 3 + 4 \times 2 = - 4[/tex]

[tex] = 12 \times (2 - 3) + (4 \times 2)[/tex]

[tex] = 12 \times ( - 1) + 8[/tex]

[tex] = - 12 + 8[/tex]

[tex] = - 4[/tex]

Answer:

The solution to the system of equation is (1,-4)

Step-by-step explanation:

Here, we want to find the solution to the system of equations

Since we have y in both places, we can equate the two

That would be;

-x-3 = -7x + 3

-x + 7x = 3 + 3

6x = 6

x = 6/6

x = 1

y = -x - 3

y = -1 -3

y = -4

So the solution to the system of equations is (1,-4)
