Answer:

x = 2.52 gallons. It is best that she buy 3 gallons of paint.

Step-by-step explanation:

Wall 1 & 2 : 26 ft by 9 ft

Wall 3 : 18 ft by 9 ft

Area 1 : 26 ft x 9 ft = 234 ft²

Area 2 : 26 ft x 9 ft = 234 ft²

Area 3 : 18 ft x 9 ft = 162 ft²

Total Area : 234 ft² + 234 ft² + 162 ft² = 630 ft²

1 Gallon = 250 ft²

630 ft² ÷ 250 ft² per gallon = 2.52 gallons

Amelia will need 2.52 gallons of paint to cover the wall space of 630 ft^2

Answer:

500 grams is 20 percent of 2.5 kg

Step-by-step explanation:

500*100 = 50,000

50,000/2500=20

500 g is the 20% of 2.5kg.

The percentage is a ratio of number as a fraction over 100.

According to the given question

we have to find the percentage of 2.5 kg

since, 500g = [tex]\frac{500}{1000}[/tex] = 0.5kg

The percentage of a quantity x is given by

percentage = [tex]\frac{Q}{value}[/tex]×100

Substitute, Q = 0.5kg and value = 2.5kg in the above formula

⇒ percentage = [tex]\frac{0.5}{2.5}[/tex]× 100 = 20%

Hence, 500g is the 20% 0f 2.5g.

Number of distinct products that can be formed is 144

Since we need to multiply two different integers to be selected from the set which contains a total of 12 integers. This is a permutation problem since we require distinct integers.

Now, for the first integer to be selected for the product, since we have 12 integers, it is to be arranged in 1 way. So, the permutation is ¹²P₁ = 12

For the second integer, we also have 12 integers to choose from to be arranged in 1 way. So, the permutation is ¹²P₁  = 12.

So, the number of distinct products that can be formed from these two integers are ¹²P₁ × ¹²P₁ = 12 × 12 = 144

So, the number of distinct products that can be formed is 144

Answer:

(- 21, - 13 )

Step-by-step explanation:

- 3y + x = 18 → (1)

x = 2y + 5 → (2)

substitute x = 2y + 5 into (1)

- 3y + 2y + 5 = 18

- y + 5 = 18 ( subtract 5 from both sides )

- y = 13 ( multiply both sides by - 1 )

y = 13

substitute y = - 13 into (2)

x = 2(- 13) + 5 = - 26 + 5 = - 21

solution is (- 21, - 13 )

Answer:

540

Step-by-step explanation:

10% of 600 is 60, 600-60 is 540

The 10% of $600 will be $60 therefore, the net salary that Mr. Smith will take home will be $540.

The percentage is defined as a given amount in every hundred. It is a fraction with 100 as the denominator percentage is represented by the one symbol %.

The percentage is also called the indicating hundredths. Thus, 2% is two-hundredth, which means 2%=2/100=0.02.

As per the given,

Base salary = $600

10% of $600 = (10/100) x 600 = $60

Net salary = $600 - $60 = $540

Hence "The 10% of $600 will be $60 therefore, the net salary that Mr. Smith will take home will be $540.".

Excuse me, sorry for using up your points, but what are the statements?

Answer:

a. 3.4t (miles)

b. 2.125 miles

c. t = 1.6 hours

Step-by-step explanation:

A) We use this relation: Distance = time * speed ( speed or vitesse or rate)

So d= 3.4*t= 3.4t (miles)

B) If t= 5/8

then the distance d= 3.4* 5/8= 2.125 miles.

C) If the distance d= 5.44, we can find the time like:

d= 3.4*t, and we know d=5.44

so 5.44= 3.4*t or t = 5.44/3.4, t= 1.6 hours

Hope you understand it.
