Answer:

-79.78 (really stinking cold)

Step-by-step explanation:

Solving the equation will go like this:

5/9(F - 32) = -62.1

multiply both sides by 9 to get rid of the fraction

5 (F - 32) = -558.9

divide both sides by 5

F - 32 = -111.78

add 32 to both sides

F = -79.78

Given the definitions of f(x) and g(x) below, find the value of g(f(5)).
f(x) = 2x – 10
g(x) = x^2 + 6x – 8

I don’t need work I am just looking for the answer !

Answers

gf(x) = g(x^-1) = x^2 + 6x - 8

f(x) = 2x - 10

gf(x) = 6 ( 2x - 10) - 8

gf(x) = 12x- 60 - 8

gf(x) = 12x -68

gf(5) = gf(x) = 12x - 68

gf(5) = 12(5) - 68

gf(5) = 60 - 68

gf(5) = -8

Two geometrically similar jugs have volumes of 1000 cm3and 512 cm3.They have circular bases. The diameter of the base of the larger jug is 9 cm.

Answers

Complete Question

Two geometrically similar jugs have volumes of 1000 cm³and 512 cm³.They have circular bases. The diameter of the base of the larger jug is 9 cm.

Calculate the diameter of the smaller jug.

Answer:

7.2 cm

Step-by-step explanation:

To solve the above question,we have the proportion

Smaller volume/ Larger volume = (Smaller diameter/ Larger diameter)³

We are to find the smaller diameter

Hence our formula is give as

Cube root(Smaller volume/ Larger volume)= Smaller diameter/ Larger diameter

=cube root( 512/1000) = x/9

= 8/10 = x/9

Cross Multiply

10x = 8 × 9

10x = 72

x = 72/10

x = 7.2cm

Therefore, the diameter of the second jug is 7.2 cm

which of the following decimal has highest value is a 0.5 b 0.12 c 0.17 d 0.8​

Answers

Answer:

d 80 cents or 0.8

Step-by-step explanation:

Change them all to money. Then look at it again.

0.5 = 50 cents

0.12 = 12 cents

0.17 = 17 cents

0.8 = 80 cents.

You get each of them by starting with a dollar. A dollar has 100 cents.

So 0.5 of a dollar is 1/2 a dollar.

1/2 a dollar is 0.5 * 100 = 50 cents

0.17 * 100 = 17 cents

0.12 * 100 = 12 cents

0.8 * 100 = 80 cents

The largest one is 8

Answer d) 0.8

Step-by-step explanation: Here is a tip, when you see a decimal like 0.5 compared to a bigger looking one like 0.12 add a 0 to the end. It will still have the same value and you won't be as confused.

0.80> 0.50> 0.17> 0.12

What is 589 divided by 31 with remainder?

Answers

Answer:

19 remainder 0

Step-by-step explanation:

When we divide 589 by 31 we get remainder 0.

Here we have to find the remainder when 589  is divided by 31

In order to this proceed with division,

Since we know that,

When the numerator is equal to or more than the denominator, the fraction is said to be inappropriate. It always has a value of one or higher. Since mixed fractions are simpler to understand, improper fractions are typically expressed in simplified mixed number form.

Now

31 ) 589 ( 19

   -  31

 _________

      279

   -  279

 __________

        0

Hence remainder after division is 0.

Louis wants to carpet the rectangular floor of his basement. The basement has an area of 363 square feet. The width of the basement is 1 3 its length. What is the length of Louis's basement? The length is feet.

Answers

Answer:

the length is 33 feet

Step-by-step explanation:

The computation of the length is shown below:

Let us assume the length be x

So the width be 1 by 3 x

And the area is 363 square feet

So

As we know that

Area = length × width

363 = x × 1 ÷ 3 x

363 = 1 ÷ 3x^2

Now

363 × 3 = x^2

1089 = x^2

x = 33 feet

hence, the length is 33 feet
