Answer:1,170 i think what are u exactly trying
to find
Step-by-step explanation:
Answer:
108
Step-by-step explanation:
So we can break this figure into 2 shapes. A rectangle and a right triangle.
Once we do that, we can solve the area for each shape.
Rectangle: 6 x 3 = 18
For the triangle, we'll need to find the sum of 6 + 6, which would be 12 to find the missing height for the triangle. Then we can find the area.
Triangle: (12 x 15)/2 = 90
We can then add our two answers up to get our final answer.
18 + 90 = 108
Simplify the expression -3÷(-2/5)
Answer:
\(\frac{15}{2}\) or 7.5 (they're the same)
Step-by-step explanation:
Write it out: \(\frac{-3}{-\frac{2}{5} }\) Simplify: \(\frac{3}{\frac{2}{5} }\) 3 ÷ 2/5 = 3 × 5/23 × 5/2 = 15/2 or 7.5Answer:
\(7\frac{1}{2}\)
Step-by-step explanation:
\(-3:-\frac{2}{5}= \\=-\frac{3}{1}*-\frac{5}{2}\\\\=\frac{-3*-5}{2}\\ \\=\frac{15}{2}\\ \\=7\frac{1}{2}\)
HELPP PLEASE LOOK AT IMAGE
Answer:
33.3%
Step-by-step explanation:
There are 3 sections the spinner can land on, and only one meets the requirement (less than 3, so the 2 section is the only one). Therefore the chance of landing on 2 is 1/3, or 0.333...... which can be converted into percentage by multiplying it by a hundred.
-0.333..... x 100 = 33.33333....

You have a pizza with diameter 12
2
3 in., and a square box that is 12.65 in. across. Write 12
2
3 as a decimal. Can you fit the pizza inside the box?
What is the decimal expansion for 12
2
3?
A.12.6
B.12.65
C.12.6
D.12.66
pls help me
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:
I believe the answer is D.
Step-by-step explanation:
Write an equation for: y equals three times the sum of x and two.
Answer:
y = 3x+2
Step-by-step explanation:
Y varies directly as X , and Y=1.2 when X=1.6.Solve for points.
Answer:
No
Step-by-step explanation:
I don' think that Y varies directly like X does because first they're different numbers. Y=1.2 and X=1.6.

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.

After 1 year, $6,000 deposited in a savings account with simple interest had earned $120 in interest. What was the interest rate?
Answer: 6000 or 120
Step-by-step explanation:
P=$6,000
R=?
T=1 year
S.I.=$120
SI=(PTR)/100
=>120=(6,000*R*1)/100
=>120=60R

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Blake was a little concerned as he stood in the middle of the overcrowded elevator. The sign clearly stated that the total weight in the elevator could not exceed 2,000 pounds.
Write an inequality to show the weight limit for the elevator.
A) w > 2,000
B) w < 2,000
C) w ≤ 2,000
D) w ≥ 2,000
Answer: C) w ≤ 2,000
Step-by-step explanation:
We know for a fact that it is not A or D, because this means that the elevator WOULD be able to handle weight more than or equal to 2,000 lbs.
This leaves us A and C.
The question states that the weight could not exceed 2,000 pounds, meaning that ≤ will be used. This gives us w ≤ 2,000. The total weight in the elevator has to be less than or equal to 2,000 pounds.

b will be the number of blue beads for the bracelet.
The number of red beads will be represented as b + 7.
Determine the expression for the total number of beads.
Then we can written it as,
= b + (b +7)
= 2b + 7.
Gina is hiking from the top of a mountain. In 24 minutes, she walks down the mountainside to a location 1,524 feet from the top of the mountain. If she walks at about the same pace, express Gina’s average change in altitude per minute.
Answer:
The change in altitude per minute is 63.5 alt/ min
What is unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
In 24 minutes = 1524 feet
So, the average Change in altitude per minute
=1524/24
= 63.5 alt/ min
hence, change in altitude per minute is 63.5 alt/ min.

Tell whether it has one solution, an infinite number of solutions, or no solutions, and identify the equation as an identity, a contradiction, or neither.
Give step by step explanation
Answer:
All Real Numbers
Step-by-step explanation:
Step 1:
24 - 3x = 8 - 2x + 16 - x Equation
Step 2:
24 - 3x = - 3x + 24 Add and Subtract
Step 3:
24 = 24 Add 3x on both sides
Answer:
All Real Numbers
Hope This Helps :)
Answer:
The equation has infinite solutions. It is an identity
Step-by-step explanation:
24-3x=8-2x+16-x
Combine like terms
-3x +24 = -2x -x +8 + 16
-3x +24 = -3x + 24
At this point it is evident that the equation is an identity.
Any real number substituted for x will result in a true equation.
