There are 20 children in a class 45% are girls, How many girls and boys are there?
Answers
Answer:
Step-by-step explanation:
each person represents 5%. so 45% are girls. 45/5 is 9, so 9 are girls. 20 minus 9 is 11 so 9 girls and 11 boys
The number of girls is 9 and the number of boys is 11.

Explanation:
A triangle is always equal to 180, therefore you would add the insides of it. 52 + 44 = 96 Than you would subtract 96 from 180 = 84 so the inside part of the triangle with the missing amount would be 84. Then that part of the triangle is adjacent so 84 would go on the outside part as well. Then you would multiply 84 by 2 and subtract the 168 from 360 and get 192.
Whats the value of x? 3x - 5(x - 5) = -7 + 2x + 12
Answers
Answer:
x = 5
Step-by-step explanation:
Given
3x - 5(x - 5) = - 7 + 2x + 12 ← distribute and simplify left side
3x - 5x + 25 = 2x + 5
- 2x + 25 = 2x + 5 ( subtract 2x from both sides )
- 4x + 25 = 5 ( subtract 25 from both sides )
- 4x = - 20 ( divide both sides by - 4 )
x = 5

Sheet metal costs $20 per square foot.
Step-by-step explanation:
7.6x - 2.3x = 106
We are finding the value of x.
5.3x = 106
Divide both sides by 5.3.
x = 106 ÷ 5.3
x = 20
Answer and Explanation
__________________________________________________________
Sheet metal costs $20 per square foot( x = 20 )__________________________________________________________
Sheet metal costs 20 dollars per square foot, and we can figure this out by multiplying the 20 by the numbers and subtracting them.
__________________________________________________________
[tex]7.6x-2.3x=106[/tex] but what does x equal? ( 20 )
[tex]7.6\cdot20[/tex] = [tex]152[/tex]
[tex]2.3\cdot20[/tex] = [tex]46[/tex]
__________________________________________________________
[tex]152-46[/tex] = [tex]106[/tex]
Which is the same in the question, so x = 20.

The Williams family goes shopping, and spend $95.00. They have a coupon for 20% off and the sales tax is 8%. What is the total cost of the shopping trip?
Answers
Answer:
The total cost of the shopping trip is:
$82.08
Step-by-step explanation:
The Williams family goes shopping, and spend $95.00. They have a coupon for 20% off and the sales tax is 8%. What is the total cost of the shopping trip?
Step 1
We find the price after the discount
The Williams family goes shopping, and spend $95.00. They have a coupon for 20% off
Hence:
20% × $95
= $19
Therefore: $95 - $19
= $76
Step 2
We find the amount of sales tax
The sales tax is 8%
Hence:
8% of $76
= $6.08
Our sales tax = $6.08
Step 3
The total cost of the shopping trip is calculated as:
$76 + sales tax
= $76 + $6.08
= $82.08

In one full rotation/revolution, a point on the edge travels a distance equal to the circumference of the gyroscope, or 2π (18 cm) = 36π cm. Convert the angular speed, 36π cm/rev, to linear speed:
(36π cm/rev) • (35 rev/min) = 1260π cm/min ≈ 3958 cm/min

Answers
Answer:
Less.
Step-by-step explanation:
The way decimals and numbers in general work, each number to the right becomes 10 times less than the one before. Therefore, adding a 0 BEFORE the numbers would make 0.058 10 times less than 0.58.

QUESTION Today, everything at a store is on sale! The store offers a 20% discount.
The regular price of a T-shirt is $18. What is the discount price?
Answers
Answer:
18x0.20 = 3.6 18-3.6 = 14.4
anwser- $14.40
Step-by-step explanation:
18 is the original price of the shirt, and 20% is the discount. You can write the discount as 0.20 because it is the same as 20/100. To get the discount you have to multiply the original price and the discount, 18x0.20, 3.6. 3.6 is the discount price which means, it is not the final price because it only is 20% of 18. To check, multiply 3.6 by 5 becuse 100%= 1 and 5 times 0.2 equals to 100% (1). 3.6 x5 = 18. To get the final price, subtract 3.6 from 18 so the dicount can be added to the final price. Hope this helps :)

Answers
Answer:
1,680
Step-by-step explanation:
n!/(n-r)!
in this case n= 8 and r= 4
so 8!/(8-4)! = 1,680
The possible permutation of 8 objects taken at 4 a time will be 1680.
What is permutation?
The linear arrangement of the set of the orders or the linear arrangements of the numbers is called the permutation.
The number of possible permutations of 8 objects taken 4 at a time will be:-
[tex]^8C_4=\dfrac{8!}{(8-4)!}[/tex]
[tex]^8C_4=\dfrac{8!}{(4)!}[/tex]
[tex]^8C_4=\dfrac{8 \times 7\times 6\times 5\times 4\times 3\times 2}{4\times 3\times 2}=1680[/tex]
Therefore the possible permutation of 8 objects taken at 4 a time will be 1680.
