You have 6 boys to every 5 girls in math class. How many boys are in class if there are 30 girls in the class.
Answer:
36
Step-by-step explanation:
no of boys = 6
no of girls= 5
Ratio = 6:5
No of girls = 30
Ration = 6:5:: x : 30 (x = 30 / 5 x 6)
= 6:5:: 36:30
I hope its right!
There are 36 boys.
Since the ratio is 6:5 and the question wants to know how many boys are in a class if there are 30 girls then all you have to do is divide 30 by 5 to get 6 (which is a key factor in this equation). After that you multiply the 6 by the original number of boys (which is also six) to get a total of 36 boys. This is an equivalent expression to the original ratio.
Original:
6:5
When there are 30 Girls:
36:6
When 36:5 is divided by 6 you get 6:5 which is the original ratio.
Hope this helps and have a nice day.

Alex deposits ₹ 12000 in a bank for 4 1/2
years at a rate of 6.5% per annum. Find the amount he will receive after 4 1/2
years
Answer:
12780
Step-by-step explanation:
The amount of money Alex would receive at the end of 41/2 years is ₹15,510.
The amount of money Alex would receive at the end of 41/2 years is the sum of the interest he would earn and the amount of money he deposited.
Interest = principal x time x interest rate
12,000 x 4.5 x 0.065 = 3510
The amount of money Alex would receive = 3510 + 12,000 = 15,510

What is the area of this figure?
Enter your answer in the box.
Answer:
400 sq. in.
Step-by-step explanation:
the parallelogram in the figure has an area of 320 sq. in.
and the right triangle at the top right has an area of 80 sq. in.
adding both areas would equal to 400 sq. in.
( if you're wondering,what about the right triangle at the bottom left?Well that triangle actually gives us the height of the parallelogram which is 16.therefore the triangle's area is already found in the area of the parallelogram.As you should know the area to a parallelogram is A=bh ,and the base is 20 so multiplying 16 x 20 that equals 320.Therefore the triangle's area is already found in the area of the parallelogram.)
Help on 6 and 7! Find the rule of each function table
-3m – 4m + 11 < -38
Be sure to include the correct variable, symbol, & number in yoru final answer.
Answer:
m < 7
Step-by-step explanation:
Given inequality
- 3 m - 4m + 11 < - 38
The give inequality can also be written as
- 3m - 4m + 11 = - 38
- 7 m = - 38 - 11
- 7 m = - 49
m = -49 / - 7
m = 7
So
m < 7

The table shows the weights of a sample of packages carried by an air freight company last month. Find the mean deviation for the data in the quantity column.
Select one:
8.09
1.52
2.84
6.18
Answer:
1.52
Step-by-step explanation:
[tex]\frac{5 + 9 + 5 + 6 + 8 }{5} = \frac{33}{5} = 6.6[/tex]
distance from 6.6
5, 1.6
9, 2.4
5, 1.6
6, .6
8, 1.4
[tex]\frac{1.6 + 2.4 + 1.6 + .6 + 1.4}{5} = \frac{7.6}{5} = 1.52[/tex]
The mean deviation of the data set is 1.52. The correct option is B.
What is mean?Mean is defined as the ratio of the sum of the number of data sets to the total number of data.
First, calculate the mean of the data set and then the deviation of each data set.
The mean is calculated as,
Mean =(5+9+5+6+8)/5
Mean = (33/5)
Mean = 6.6
The deviation is,
5 1.6
9 2.4
5 1.6
6 0.6
8 1.4
The mean deviation is calculated as,
Mean = ( 1.6 + 2.4 + 7.6 + 0.6 + 1.4 ) / 5
Mean = 7.6 / 5
Mean = 1.52
Therefore, the mean deviation of the data set is 1.52. The correct option is B.

1.Cesiah has a pencil box containing 4 green pencils, 6 blue pencils, and 10 red pencils. If she randomly selects a pencil from the bag, what is the probability, in decimal form, that she picks a green pencil?
Answer:
If you add up the amount of pencils there are then you get 20,
so that means that you have 20 pencils in all, and out of the 20 pencils, 4 of them are green so the probability is 4/20
and 4/20 in decimal form is 0.2, so the probability is unlikely that she will pick a green pencil
