Answer:

F. 5:4

Step-by-step explanation:

Solve for a and c to find the ratio of a to c:

  • 2a = 3b
  • a = 3/2(b)
  • 6b = 5c
  • c = 6/5(b)

Now, we can use the value of a and c to find the ratio of a to c:

  • (3/2(b))/(6/5(b))
  • 3b/2 × 5/6b
  • 15b/12b
  • 5/4

F. 5:4 is the correct answer

​ On a certain hot​ summer's day, 335 people used the public swimming pool. The daily prices are $1.25 for children and $2.00 fo
spin [16.1K]

Answer:

57

Step-by-step explanation:

Let c represent the number of children ($1.75 each) and a represent the number of adults ( $2.00 each).

We know that there were 340 people total, so c + a = 340. This implies that a = 340 - c

We also know that $1.75 c + $2.00 a = $609.25

By substituting a with 340 -c we have $1.75 c + $2.00 (340 -c) = $609.25

Use the distributive property to obtain $1.75 c + $680 - $2.00 c = $609.25

Subtract $680 from both sides and combine like terms to get - $0.25 c = -

$70.75

Now, divide both sides by -$0.25 to get c = 283, the number of children.

The number of adults is 340 - c or 340 - 283 = 57

What is the solution to the equation?<br><br> r/7.1 = 4.2
victus00 [196]

Answer:

r = 29.82

Step-by-step explanation:

We have the equation r/7.1 = 4.2 and are asked to solve for r.

To solve, we need to isolate r, do as followed and multiply 7.1 from both sides:

r/7.1 = 4.2

r = 29.82

Zubin has two pieces of string. One piece is 36 inches long and the other is 48 inches long. He wants to cut them into equal pie
skelet666 [1.2K]

Answer:

12 pieces each:

S_1 = 3\ in

S_2= 4\ in

Step-by-step explanation:

Given

S_1 = 36\ in -- first string

S_2 = 48\ in --- second string

Required

Determine the number of equal pieces

To do this, we first calculate the HCF of the length of both pieces (36\ and\ 48)

36 = 2 * 2 * 3 * 3

48 = 2 * 2 * 2 * 2 * 3

Common\ prime\ factors = 2, 2\ and\ 3

The HCF is:

HCF = 2 * 2 * 3

HCF = 12

<em>Hence, he can cut both strings to 12 pieces each</em>

<em></em>

<em>Recall that </em>

S_1 = 36\ in

<em>The first string can then be cut in to 3 inches each (i.e. 36/12)</em>

S_2 = 48\ in

<em>The first string can then be cut in to 4 inches each (i.e. 48/12)</em>
