Given:

A blueprint of a house shows a wall that is 5 inches long.

The blue pretty strong to a scale of 1:60.

To find:

The actual width of the wall in the house.

Solution:

The blue pretty strong to a scale of 1:60.

It means, the dimensions of blueprint to the actual house is 1:60.

Width of a wall in blue print = 5

Let the actual width of the wall in the house be x.

[tex]\dfrac{5}{x}=\dfrac{1}{60}[/tex]

[tex]5\times 60=1\times x[/tex]

[tex]300=x[/tex]

Therefore, the width of the wall in the house is 300 inches.

Answer: I hope this will help too.

Answer:

x > 14

Step-by-step explanation:

Let the number of hours nathans volleyball team trains in a week be x

If the number 14 is less than the number of hours nathans volleyball team trains in a week, this is expressed as;

14 < x

Rearranging the inequality expression will reverse the inequality sign as shown;

x > 14

Hence the inequalities that represents the number of hours that the volleyball team trains in a week is x > 14

Answer:

Step-by-step explanation:

5y + x = 25

Subtract x from both sides when x = 5

5y + x - x = 25 - x

5y = 20

5y/5 = 20/5

Answer:

x=9

Step-by-step explanation:

If x varies directly with y, a ratio can be used to find the new x value. The ratio will look like this [tex]\frac{27}{6}=\frac{x}{2}[/tex]. In order to solve this ratio, cross multiply to get 6x=54. Now, this can be solved by dividing both sides of the equation by 6 in order to get the answer that x=9

Answer:

(6,-10)

Step-by-step explanation:

(-2*6)+2=-10, and the 6 is the X value, the -10 is the Y value.

Answer:

f(6) = -10

Step-by-step explanation:

Plug in 6 for x in the given equation:

f(x) = -2x + 2

f(6) = -2(6) + 2

Remember to follow PEMDAS. PEMDAS is the order of operation, and stands for:

Parenthesis

Exponents (& Roots)

Multiplication

Division

Addition

Subtraction

~

First, multiply. Note that when you are multiplying one negative number and one positive number together, your answer will be negative:

f(6) = -2(6) + 2

f(6) = (-2 * 6) + 2

f(6) = (-12) + 2

Next, simplify. Subtract:

f(6) = -12 + 2

f(6) = -10

-10 is your answer when f(6).

Answer:

6.44

Step-by-step explanation:

Since, there is a 4 in the hundredths and in the thousandths place there is a 3, then the answer should round off to 6.44 because you only round the 4 up to a 5 if the number in the thousandths place is 5 or greater.

Hope this helps!

The total number of flowers in shipment is 180.

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

The ratio of flowers,

red: blue: white = 3:1:2

Let red flowers are 3x,

Red flowers are x,

and white flower are 2x.

Therefore, total number of flowers = 3x+x+2x = 6x

Given that,

The total number of white flowers = 60

⇒2x = 60

x = 30

Total number of flowers = 6x = 6×30 = 180

There are 180 flowers in the shipment.

Answer:

answer is »»»4. 3

Step-by-step explanation:

Use a factor tree to express 60 as a product of prime factors. So the prime factorization of 60 is 2 × 2 × 3 × 5, which can be written as 2 2 × 3 × 5. The actual prime factors of 60 are 2, 3, and 5.

Answer:

A=45

B=110

Step-by-step explanation:

Interior angles of a triangle add up to 180.

So, do 180-25=155.

Then, 155-65=90.

90 divided by 2 is 45.

x=45 so B is 45+65, which is 110.
