Answer:
D
Step-by-step explanation:
This is because the formula is 4×pi×r^2
So 4×pi×7^2
(7^2=49) now plug that in: 4×pi×49
Combine like terms: 4×49=196
Plug that into the equation: 196pi
7 + 3 (2x - 5) = 3x + 7
Answer:
x = 5
Step-by-step explanation:
Given
7 + 3(2x - 5) = 3x + 7 ← distribute parenthesis and simplify left side
7 + 6x - 15 = 3x + 7
6x - 8 = 3x + 7 ( subtract 3x from both sides )
3x - 8 = 7 ( add 8 to both sides )
3x = 15 ( divide both sides by 3 )
x = 5

Answer:
a.) 0.51
b.) 1445
Step-by-step explanation:
a.) 5.1 x 10^-1 can be written as 5.1 x 0.1 which equals 0.51.
b.) 1.7 x 10^4 x 8.5 x 10^-2 can be simplified either by condensing 10^4 and 10^-2 to equal 10^2, or substituting the expression into a calculator.
This should equal 1.7 x 8.5 x 10^2 or 1445.

A radius of 1 meter. What’s the area. Use 3.14 for pi
Answer:
A is 3.14
Step-by-step explanation:
. good day.hope it helps
Answer:
Step-by-step explanation:
circumference = 2 * pi * radius
Plug in 4 meters for radius and 3.14 for pi .
circumference ≈ 2 * 3.14 * 4 m
Multiply these together.
circumference ≈ 25.1 m
area = pi * radius2
Plug in 4 meters for radius and 3.14 for pi .
area ≈ 3.14 * (4m)2
Square the 4m .
area ≈ 3.14 * 16m2
Multiply.
area ≈ 50.2 m2

I have 0.0254 it and they say approximately to 2 decimal place will I include the 0 after the decimal point
Yes. You have to include 0.
If we round off this value to 2 decimal places then it is
0.03
Reason: after decimal point or before decimal point if you have to drop some digits and if the digit to be droped are 5 followed by non zero digit then previous digit is increased by 1.
Here, the digits to be droped are 5 and 4 after 0.02 so we increase 2 by 1 that is 3.

13. Every Friday, milkshakes are on sale at The Ice Cream Shoppe with a 15% discount.
13a) The regular price of a milk shake is $4. What is the discount price?
13b) If the regular price of a shake is X dollars, what is the discount price in dollars?
13c) On your birthday, the discount price of an ice cream cake is $22. What is the regular price?
(*I really need help on this T^T*)
Answer:
13a) $3.40
13b) 0.85X
13c) $25.88
Step-by-step explanation:
13a) When there is a 15% discount, we can say that we are only paying 85% of the original price because out of 100%, 15% is taken away. 85% in decimals is 85/100 = 0.85.
$4 x 0.85 is the discounted price, which is $3.40
13b) In 13a, the price was 4. Now, the price is X. Hence we plug in (substitute) X in for 4, giving us X x 0.85, which we can write as 0.85X
13c) 85% of the cake is $22. To find 100% of the price, we can find 1% of the original price and then multiply that by 100, which gives us 100% of the price.
We know 85% of the original price. Therefore, dividng the price by 85 will give us 1% of the price. 1% = $22/85
Finally, to calculate 100%, we multiply by 100.
22/88 x 100 = 440/17 which is 25.882 in decimals, which we round to 2 decimal places (because it is currency) = $25.88

Answer:
1. B.
2. A, E.
3. D.
Step-by-step explanation:
1. 8.225 ÷ 5 = 1.645
2. 892 ÷ 8 = 111.5
8920 ÷ 80 = 111.5
894 ÷ 10 = 89.4
89.2 ÷ 0.08 = 1115
8.92 ÷ 0.8 = 11.15
0.892 ÷ 0.008 = 111.5
