a school has 60 girls and 90 boys. the ratio of girls to boys
Answer:
60:90
Step-by-step explanation:
The ratio of girls (G) to boys (B) is 2 : 3.
Let the girls be represented by G.Let the boys be represented by B.Given the following data:
Number of girls = 60 girlsNumber of girls = 90 boysIn this exercise, you're required to find the ratio of girls (G) to boys (B). In order to do this, we would divide the two values to the least.
[tex]G : B = 60 : 90[/tex]
Dividing both sides by 30, we have;
[tex]G : B = \frac{60}{30} : \frac{90}{30} \\\\G : B = 2 : 3[/tex]
Therefore, the ratio of girls (G) to boys (B) is 2 : 3.

Find the lateral and surface area of the figure.
Answer:
A.
Lateral area (LA) = 324 cm²
Surface area = 432 cm²
Step-by-step explanation:
✔️Lateral area of the triangular prism = perimeter of the base (P) × height of prism (L)
Perimeter (P) = 9 + 12 + 15
Perimeter (P) = 36 cm
height of prism (L) = 9 cm
Lateral area (LA) = 36 × 9 = 324 cm²
✔️Surface area = bh + LA
b = 9 cm
h = 12 cm
LA = 324 cm²
Surface area = 9*12 + 324
= 108 + 324
Surface area = 432 cm²

In the following triangle, find the values of the angles Band B, which are the best approximations to the solutions to this ambiguous case?
Answer:
B. B = 70.5° or B' = 109.5°
Step-by-step explanation:
(sin 45°)/13.5 = (sin B)/18
sin B = (18 * sin 45°)/13.5
sin B = 0.9428
B = sin^-1 0.9428
B = 70.5°
B' = 180° - 70.5°
B' = 109.5°

Sunni is riding a raft down a stream that is moving at a rate of 75 feet per minute how far downstream does she travel in 5 minute?
Answer: 375 feet
Step-by-step explanation:
From the question, we are given the information that Sunni is riding a raft down a stream that is moving at a rate of 75 feet per minute.
To calculate how far downstream that she can travel in 5 minute, we have to multiply the distance covered per minute by 5. This will be:
= 75 feet × 5
= 375 feet

20 men can complete a piece of work in 24 days how many men should be subtracted to finish the work in 32 days?
Answer:
5 men should be subtracted.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
As these measures(number of men needed and time) are inversely proportional, we multiply the lines instead of cross multiplication.
How many men should be working to complete the work in 32 days?
20 men - 24 days
x men - 32 days
Then
[tex]32x = 20*24[/tex]
[tex]x = \frac{20*24}{32}[/tex]
[tex]x = 15[/tex]
How many men should be subtracted?
There are 20 to complete in 24 days.
15 are needed to complete in 32 days.
20 - 15 = 5
5 men should be subtracted.
Aaron bought 7 packs of balloons for the party. There were 50 balloons in each bag. 40 of the total number of balloons were yellow. How many balloons were not yellow?
Answer:
[tex]total \: balloons = (50 \times 7) \\ = 350 \: balloons \\ none \: yellow \: balloons = 350 - 40 \\ = 310 \: none \: yellow \: balloons[/tex]
Answer:
310
Step-by-step explanation:
The equation that we would use to solve this problem is 7 × 50 - 40 = b
(b is the number of non-yellow balloons)
Since Aaron bought 7 packs of balloons with 50 balloons in each pack, we would need to multiply 7 and 50 to find the total amount of balloons that he bought.
7 × 50 = 350.
Now we subtract 40 (the total number of yellow balloons) from 350 (the total number of balloons), to find the amount of balloons that are not yellow.
350 - 40 = 310
