Answer:
7920, 2925
Step-by-step explanation:
The four-digit number has to be a multiple of 5 and also a multiple of 9. So, the last number is either a 0 or a 5, and the addition of the 4 digits must be equal to 9, 18, 27, et cetera, like every multiple of 9.
For the case: _920, the addition of digits gives 11, then the only possible first digit is 18-11 = 7
For the case: _925, the addition of digits gives 16, then the only possible first digit is 18-16 = 2

A Consider the cube shown below. Identify the two-dimensional shape of the cross-section if the cube is sliced horizontally
B Starting with the same cube, identify the two-dimensional shape of the cross section if the cube is sliced vertically.
C Explain why the shapes are the same or different.
Answer:
A. Square
B. Squares
C. They have the same shape, congruent corresponding angles (meaning the angles in the same places of each shape are the same) and equal scale factors.
Step-by-step explanation:
A. Since a cube has its faces shaped in square and all the edges of the cube are equal in length. Therefore, when we cut the cube by a plane, we get a square shape.
B. A vertical cut is an up and down cut. This shape is a cube, which has a base and sides in the shape of squares; thus, the two dimensional shape is a square.

Find the mean of absolute deviation for the set of values

(1) The mean absolute deviation for the given data set is 18.
The mean absolute deviation (MAD) is a way of measuring of data variability that is defined as the average of each data point's absolute deviation from the mean. To calculate the MAD, first compute the mean of the data set, then subtract each data point from the mean and calculate the absolute value of the result.
Here is the step-by-step process for finding the MAD for the given data set:
Find the mean of the data set: (108 + 53 + 47 + 22 + 56 + 62) / 6 = 56
Subtract the mean from each data point:
108 - 56 = 52
53 - 56 = -3
47 - 56 = -9
22 - 56 = -34
56 - 56 = 0
62 - 56 = 6
Take the absolute value of each result:
|52| = 52
|-3| = 3
|-9| = 9
|-34| = 34
|0| = 0
|6| = 6
Find the average of the absolute deviations: (52 + 3 + 9 + 34 + 0 + 6) / 6 = 18
So, the mean absolute deviation for the given data set is 18.
(2) The mean absolute deviation for the given data set is 2.7
Find the mean of the data set: ( 12.2 + 6.8 + 3.4 + 8.8 ) /4 = 7.8
Subtract the mean from each data point:
12.2 - 7.8 = 5.4
6.8 - 7.8 = - 1
3.4 - 7.8 = - 4.4
8.8 - 7.8 = 1
Take the absolute value of each result:
|4.4| = 5.4
|-1| = 1
|-4.4| = 4.4
|1| = 1
Find the average of the absolute deviations: (5.4+ 1 + 4.4 + 1) / 4 = 2.95
So, the mean absolute deviation for the given data set is 2.95.

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143
The table represents the relationship between the number of employees scheduled per estimated customer at a bookshop. The graph represents the relationship between the number of employees scheduled per estimated customer at a café.
Answer:
Step-by-step explanation:
Calculate each numbered angle measure.
Answer:
m1 = 90°
m2 = 68°
m3 = 112°
m4 = 112°
m5 = 68°
m6 = 44°
m7 = 112°
m8 = 112°
Concept used:
- The sum of the internal angles of a triangle is 180
- With two parallel line and one oblique, the angles internal and opposite are congruent (ex: m3 and m4)
- An isosceles triangle has the base angles congruent
Step-by-step explanation:
m1 is a rectangle angle
m2 is 180-m1-22
m3 is 180-m2
m5 is 180-m4
m6 is 180-m5-m5
m3 = m4 = m7 = m8

Find The value of H:
S=2πr(r+h)
Answer:
[S / (2πr)] - r = h
Step-by-step explanation:
You can't solve for H because there isn't a capital H in the equation. However, I'm going to pretend its "h" because that might have been a mistake.
S = 2πr(r + h)
Divide by 2πr to try to isolate h
S / (2πr) = r + h
Subtract r from both sides to get h by itself
[S / (2πr)] - r = h
That is your final answer.
\(\\ \rm\Rrightarrow S=2\pir(r+h)\)
\(\\ \rm\Rrightarrow r+h=\dfrac{S}{2\pi r}\)
\(\\ \rm\Rrightarrow h=\dfrac{S}{2\pi r}-r\)
\(\\ \rm\Rightarrow h=\dfrac{S-2\pi r^2}{2\pi r}\)
In a city, there are 16 swimming pools. On weekends, 6 of the pools are open.
George says the ratio of pools open on weekends to the total number of pools is 6:16.
Emma says the ratio of pools open on weekends to the total number of pools is 6:11.
Which student is correct? Explain.
Answer:George
Step-by-step explanation: George is correct because Emma said that the total number of pools in the city is 11 even though it says there are 16 pools in the city, but she got the number of how many are open, George is right because it says what is the ratio of pools open on the weekends to the total amount of pools, and it says there are 6 pools open on the weekend and there are 16 pools in the city in total so he would do 6:16.
George is correct they said that the ratio of pools open on weekends to the total number of pools is 6:16.
What are ratios and proportions?A ratio is an ordered pair of numbers a and b, denoted by the symbol a / b, where b does not equal zero. A proportion is an equation that sets two ratios equal to each other. For example, if there is one boy and three girls, the ratio could be written as 1: 3. (for every one boy there are 3 girls) One-quarter are boys and three-quarters are girls.
Given that In a city, there are 16 swimming pools. On weekends, 6 of the pools are open.
George says the ratio of pools open on weekends to the total number of pools is 6:16.
Emma says the ratio of pools open on weekends to the total number of pools is 6:11.
George is right that the ratio of the open pools to the total pools will be 6:16.

Taylor had $60 dollars to buy a new pair of sneakers. He saw a pair he really liked that originally cost $72 but were on sale for 15% off. Does Taylor have enough money to buy them on sale?
Answer:
No.
Step-by-step explanation:
72 times 0.15=10.8
72-10.8=61.2
No. Taylor doesn't have enough.
You could also have done 72 times 0.85, and then you wouldn't have had to minus 10.8 and all those stuff.

A) 30∘
B) 31∘
C) 32∘
D) 33∘
HELP PLEASE LOOK AT THE IMAGE NO WRONG ANSWERS
Answer:
D) 33 degrees
Step-by-step explanation:
All interior angles of a quadrilateral must equal 360 degrees.
We have 3/4 angles, so let's write an equation:
360=x+265+32+30
simplify
360=327+x
subtract 327 from both sides
33=x
So, D is the correct option.

Answer: question one equals one mile and 206 feet. the second question equals 29 yards and 1 foot. the third question equals 2 miles and 25 yards.
Step-by-step explanation: one mile equals 5280 feet. 5486-5280= 206, so 1 mile and 206 feet.
one yard equals 3 feet. 29 x 3= 87, so there are 29 yards and 1 foot.
one mile equals 1760 yards. 1760 x 2= 3520. 3545-3520= 25, so there are 2 miles and 25 yards.

The graph shows the number of hours that Tammy spends typing for work, x, and the amount of pay that she earns, y.
On a graph titled Tammy's Pay, number of hours is on the x-axis and pay in dollars is on the y-axis. A line goes through points (2, 18) and (8, 42).
What does the y-intercept represent?
Answer: The y-intercept is the initial amount Tammy earns.
Step-by-step explanation:
Always remember that for graphs, the y-intercept is the initial amount. In this case, it would be the initial amount or the very first amount Tammy earns. If the line goes through the origin (0,0), that means that Tammy earns $0.00 for 0 hours of working.
