Answer:
8.5
Step-by-step explanation:
Because I used a calculator
The square root of 72 is 8.48528137424 ...
The hundredths digit (8) rounds up.
So the square root of 72 rounded to the nearest tenth is 8.5.
Now you can multiply this to see if the product is near 72.
8.5 times 8.5 is 72.25.
Jack wants to know how much water a sphere can hold with a radius of 8 cm. Find the volume. Use 3.14
for pi.
a
2144.7 cm
b
254 cm
С
83.6 cm
d
2220 cm
Answer:
a
Step-by-step explanation:
Volume of water in sphere is 2,143.57 cm³
Given that;Radius of sphere = 8 cm
Value of π = 3.14
Find:Volume of water in sphere
Computation:Volume of sphere = (4/3)πr³
Volume of water in sphere = (4/3)(3.14)(8)³
Volume of water in sphere = (4/3)(3.14)(512)
Volume of water in sphere = 2,143.57 cm³

a)
3/5 = ./20
b)

Answer:
a)12/20
because 5 × 4 = 20 so, 3 also needs to multiply by 4
b)5/6
because 30 ÷ 6 = 5, and 6 × 5 = 30,so, 25 needs to ÷ with 5
Rewrite the problem using fewer words. Leave out information that you do not need to solve the problem. Then solve the problem. For a science project, you record the high temperature each day. The high temperature on Day 1 was 6°less than on Day 4 and 4°less than on Day 10. The high temperature on Day 10 was 62°F. What was the high temperature on Day 1?
Answer:
Each day, you record the high temperature* (you don't necessarily need to say that it is for a science project). On Day 1, it was 4* less than Day 10**. It hit 62* F on Day 10. What was the high temperature on Day 1?
Because we know that on Day 1, the temperature was 4* less than on Day 10, and the high temperature on Day 10 was 62*, the high temperature on Day 1 was therefore 58*. Because 62 - 4 = 58.
Step-by-step explanation:
*You don't necessarily need to say that it was for a science project.
**The information for Day 4 is irrelevant too because we are not given the temperature for Day 4, therefore it does not help us find the answer.

Hi. I need help with these questions (see image)
Please show workings.
Answer:
see explanation
Step-by-step explanation:
Using the chain rule
Given
y = f(g(x)), then
[tex]\frac{dy}{dx}[/tex] = f'(g(x)) × g'(x) ← chain rule
and the standard derivatives
[tex]\frac{d}{dx}[/tex] ([tex]log_{a}[/tex] x ) = [tex]\frac{1}{xlna}[/tex] , [tex]\frac{d}{dx}[/tex](lnx) = [tex]\frac{1}{x}[/tex]
(a)
Given
y = [tex]log_{a}[/tex][tex]\sqrt{(1+x)}[/tex]
[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1}{lna\sqrt{(1+x)} }[/tex] × [tex]\frac{d}{dx}[/tex] ([tex](1+x)^{\frac{1}{2} }[/tex]
= [tex]\frac{1}{lna\sqrt{(1+x)} }[/tex] × [tex]\frac{1}{2}[/tex] [tex](1+x)^{-\frac{1}{2} }[/tex] × [tex]\frac{d}{dx}[/tex] (1 + x)
= [tex]\frac{1}{lna\sqrt{(1+x)} }[/tex] × [tex]\frac{1}{2\sqrt{(1+x)} }[/tex] × 1
= [tex]\frac{1}{2lna(1+x)}[/tex]
= [tex]\frac{1}{(1+x)lna^2}[/tex]
(b)
Given
y = ln sinx
[tex]\frac{dy}{dx}[/tex] = [tex]\frac{1}{sinx}[/tex] × [tex]\frac{d}{dx}[/tex](sinx)
= [tex]\frac{1}{sinx}[/tex] × cosx
= [tex]\frac{cosx}{sinx}[/tex]

A $280 suit is marked down by 30%. Find the sale price.
The sale price is $
The sale price of suit will be $196.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
A $280 suit is marked down by 30%.
Now,
Since, A $280 suit is marked down by 30%.
Hence, The sale price = $280 - 30% of 280
= $280 - 30/100 × 280
= $280 - $84
= $196
Thus, The sale price of suit = $196.

In Zimbabwe the rate of inflation hit 90 sextillion percent in 2009, with prices increasing tenfold every day. At that rate, how much
would a $14 wool blanket cost five days later?
Hint: Use the following equation to calculate future price: Future price = (current price) * (inflation rate)^t where t the number of days
in the future.
Instructions: Round your response to one decimal place.
_million?
Five days later the wool blanket would cost $ 1,400,000.
Given that in Zimbabwe the rate of inflation hit 90 sextillion percent in 2009, with prices increasing tenfold every day, to determine, at that rate, how much would a $ 14 wool blanket cost five days later, the following calculation must be performed:
Future price = (current price) * (inflation rate) ^ number of days
X = 14 x 10 ^ 5
X = 14 x 100,000
X = 1,400,000
Therefore, five days later the wool blanket would cost $ 1,400,000.

4. One number is 16 more than another. The ratio of the smaller number to
the larger number is 3: 7. What is the value of the smaller number?
Answer:
12
Step-by-step explanation:
So if the difference between the two number is 16 and the distance between the two numbers in the ratio is 4, that means the real numbers are 4 times greater than the ratio (because 4 * 4 = 16).
This means that you can multiply both sides of the ratio by 4 to get the two numbers 3: 7 --> 3*4: 7 * 4 --> 12: 28.
This means that the smaller number is 12.
hope that makes sense!
