Divide 33 photos into two groups so the ratio is 4 to 7

Answers

Answer 1

Answer: The number of parts is:
4+7= 11

33 photos/ 11 parts= 3 photos/part

Group 1: 4 parts* (3 photos/ 1 part)= 12 photos
Group 2: 7 parts* (3 photos/ 1 part)= 21 photos

Answer 2

Answer: 4:7
4x:7x

4x + 7x = 11x

11x = 33
x =3

4 x 3 = 12
7 x 3 = 21

So 12 and 21 are in a ratio of 4:7 and add up to 33

Answer:

the answer is A i know bc i took the test and got a 100

Step-by-step explanation:

find a two-digit number such that three times the tens digit is 2 less than the unit's digit and twice the number is 20 greater than the number obtained by reversing the digits.

Answers

Let's name these two digits as a (tens digit) and b (units digit) and then rephrase the problem statement using a and b.

The part of the sentence "three times the tens digit is 2 less than twice the units digits" translates into:

3a = 2b - 2

Considering that both a and b have to be integer numbers less than 10 and that a will have to be an even number

(since 2b - 2 is always even and for 3a to be even, a will have to be even),

the only possible options that will satisfy this equation are: 47 and 24.

The second part of the problem statement does not make much sense.

What exactly is twice the number obtained by reversing the digits?

In case of 47, twice the number obtained by reversing the digits is 2*74 = 148.

In case of 24, twice the number obtained by reversing the digits is 2*42 = 84.

An electrician needs 3 1/4 rolls of electrical wire to wire each room in a house. How many rooms can he wire with 9 1/4 rolls of wire

Answers

Number of rooms can be wired by electrician is approximately 3

Solution:

Given that electrician needs $3(1)/(4)$ rolls of electrical wire to wire each room in a house

To find: number of rooms can he wire with $9(1)/(4)$ rolls of wire

From given information,

Rolls of wire needed for 1 room = $3(1)/(4) = (4 * 3 + 1)/(4) = (13)/(4)$

Total rolls of wire = $9(1)/(4) = (4 * 9 + 1)/(4) = (37)/(4)$

So number of rooms can be wired:

$\text{ number of rooms }=\frac{\text{ total rolls of wire}}{\text{ wire needed for 1 room}}$

$\text{ number of rooms } = ((37)/(4))/((13)/(4)) = (37)/(4) * (4)/(13) = (37)/(13)$

$\rightarrow(37)/(13) = 2.84 \approx 3$

Thus number of rooms can be wired is $(37)/(13)$ or approximately 3 rooms

David and Amanda are trying to figure out how long they can live off their $12,350 savings if they spend $240 each month. They have each created an equation.

Answers

You have to divide 12,350 by 240 and that will give you your answer a.k.a
12,350/240=approximately 52 months or 4 years
