Answers
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:
40%
Step-by-step explanation:
If 60 out of 100 were oatmeal, 60% would be oatmeal.
20 lemon + 20 chocolate = 40
40 out of 100 is 40%
To confirm add 60 and 40;

Step-by-step explanation:
Sense there is 100, that makes it easy.
60% is oatmeal
20% is lemon
20% is chocolate
20 + 20 = 40
So its 40% were NOT oatmeal

\(13.5 m^{2}\)
Step-by-step explanation:
area = length × width
= 15m × 9/10m
= 15m × 0.9m
= \(13.5 m^{2}\)
Answer:
\(\Huge \fbox{Area = 13.5 m^{2}$}\)
Step-by-step explanation:
To find the area of the baseboard, we need to multiply the length by the width:
The length of the baseboard is given as 15 metres. The width of the baseboard is given as \(\frac{9}{10}\) metre.To multiply these values, we can convert the width to a decimal by dividing the numerator (9) by the denominator (10):
\(\frac{9}{10} = 0.9\)Now we can multiply the length and width:
\(\text{Area = Length $\times$ Width}\)\(\text{Area = 15 m $\times$ 0.9 m}\)\(\text{Area = 13.5 m^{2}$}\)Therefore, the area of the baseboard is 13.5 m².

4 miles per hour
Step-by-step explanation:Unit rate is the rate of something per 1 unit. In other words, the unit rate is x units per 1 unit. In this situation, the unit rate is how many miles Hassan walks in 1 hour.
Proportion
First, to find the rate of anything we can set up a proportion. In the question, the rate is described as miles per hour, so the miles will be the numerator and the hours will be the denominator.
This creates the proportion \(\frac{12miles}{3hours}\)So, the rate we are given is 12/3.
Unit Rate
To find the unit rate we need to make the denominator equal to 1. To do this, divide both the numerator and denominator by 3.
12/3 equals 43/3 equals 1So, this means that the new proportion is 4/1. Next, we can add our units, which means that Hassan walks 4 miles per 1 hour.
Graph
Now we can resize the bar graph. The purple bar should be set to 4 because this represents the miles. Then, the green bar should be set to 1 because it represents the hours.

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of
X = 2.5

Step-by-step explanation:
when you multiply 7 by 5 you get 35 which is on the bottom side. So, to get x you multipy 6 and 5 and that equals 30.
Answer:
1) its 30 because when you divide 35by 7 you get 5 and you then multiply 6x5=30
2) I really don't know this one, but my guess is 8 because when you look at the 45 and 18 its 27 difference and we then do the same for the 35-27=8

Answer:
False
Step-by-step explanation:
Lets take an example triangle. The height is 4 and the base is 6. The area of this triangle is: 4x6=24, 24/2=12. Since increasing it by 100% is the same as doubling we get a height of 8 and a base of 12. Now we find the area of our new triangle: 8x12=96, 96/2=48. 48 is not 12 increased by 100% so this is false.

What is the volume, in cubic inches, of a cone that has a radius of 9 inches and a height of 16 inches? Use 3.14 for π (pi), and round to the nearest hundredth.
Answers
Answer:
The volume (V) of a cone can be calculated using the formula: V = (1/3)πr^2h, where r is the radius and h is the height.
Substituting the given values, we get:
V = (1/3) x 3.14 x 9^2 x 16
Calculating this expression gives us:
V = 1810.08 cubic inches
Rounding to the nearest hundredth gives us:
V ≈ 1810.08 cubic inches (rounded to two decimal places)
Therefore, the volume of the cone is approximately 1810.08 cubic inches.
Answer:
1363.04
Step-by-step explanation:
V = (1/3) * 3.14 * 9^2 * 16
Simplifying:
V ≈ 1363.04 cubic inches

Next, we multiply 5 by 12: 5(12) = 60.
Then, we combine the like terms: -3 - 60 + 16 - 32 = -79.
Therefore, -3 - 5 (8 + 4) + 16 - 32 = -79.
