Answer:
C
Step-by-step explanation:
Let's say y=5
(5*40)+(5*8)
200+40=240
48*5=240
Option C is true because y*40 in the first parenthesis is equal to 40y, and y*8 in the second set of parenthesis is equal to 8y. When combined, the sum is 48y; therefore equivalent to the provided expression of y*48.

A rectangular prism has a length of 7 cm, a width of 4 cm, and a height of 212cm. The prism is filled with cubes that have edge lengths of 12 cm. How many cubes are needed to fill the rectangular prism? Enter your answer in the box.
Answers
Answer:
first solve the volume of the rectangular prism
V = l x w x h
where l is the length
w is the width
h is the height
V = 7 x 4 x 2.5
v = 70 cu cm
then solve the volume of the box
v = e^3
v = 0.5^3
v = 0.125
number of cubes = 70 / 0.125
number of cubes = 560 cubes

The product of ages of Hasni and Alia is 32 years. Hasni is 4 years older than Alia. How old are Hasni and Alia?
Answers
This gives us 8 and 4, and since Hasni js 4 years older than Alia, Hasni must be 8 years old and Alia must be 4 years old.
If the product of the ages of Hasni and Alia is 32 years and Hasni is 4 years older than Alia, then Hasni would be 8 years old while Alia would be 4 years old.
How to determine the agesFirst, the question states that the product of the ages of Hasni and Alia is 32 years old. We can represent mathematically in the following way;
ab = 32
Assuming b = a + 4, then we would have;
a(a + 4) = 32 years
a² + 4a = 32 years
a+8)(a - 4) = 32 years
So, the ages are expressed as follows:
x + 8 = 0 or x - 4 = 0
Hasni's age is 8 while Alia's age is 4.

This is a riddle that showed up in the first few pages of the poetry book "inside out and back again" I was just wondering if anyone had answers, please try it out I would appreciate it!!
Answers
Answer:

In order to calculate the time it took, multiply 6.76 by 26/60. This is due to the formula d=rt. Then add that result to 5∗5.55/10. Then, subtract that result from 11.54.
= 11.54−3.85433333333
=9.53566666667
Now, divide it by the regular speed of 9 km/hr.
= 1.05951851852 hours.
Multiply the decimal part by 60.
=1 hour 3.571 minutes.
Multiply the decimal part again by 60.
=1 hour 3 minutes 34 seconds.

describe a sequence of transformations that maps figure a to figure b
Answers
Answer:
rotate CCW 90°dilate by a factor of 2Step-by-step explanation:
First of all, we need to discover the relation Figure B has to Figure A.
Figure B has dimensions that are twice those of Figure A, so a dilation by a scale factor of 2 will be required. The "points" of figure A are on its "south" side, while those of figure B are on its "east" side. Rotation 90° CCW will be involved.
If we consider just these two transformations, we find that they are sufficient to map A to B without any additional translation. Since both transformations use the origin as a reference, their order does not matter.
__
Rotating figure A by 90° CCW moves the vertex of its "notch" from (2, 2) to (-2, 2). Dilating the rotated fibure by a factor of 2 moves its "notch" vertex to (-4, 4), as shown in Figure B.
A suitable sequence of transformations is ...
Rotation 90° CCWDilation by a factor of 2 about the originThese can be done in either order.
_____
Additional comment
The transformations are ...
(x, y) ⇒ (-y, x) . . . . . . rotation 90° CCW
(x, y) ⇒ (2x, 2y) . . . . dilation by a factor of 2
The composition of these transformations is ...
(x, y) ⇒ (-2y, 2x)
Answer:
dilate by a factor of 2

A Ferris wheel rotates three times when it travels 235.5 feet. Find the diameter of the Ferris wheel. Use 3.14 for pi
Answers
Answer:
try 3.14 x 3.14 / 235.5 and that should be your awnser.
Step-by-step explanation:
the equation for diameter is d=2r which is pi times pi divided my the number. if i remeber correctly. lmk if im wrong
Answer: The diameter is 10cm
Step-by-step explanation:
First, we divide 78.5/3.14 which = 25
Now, we find the square root of 25 to find the radius, which is 5.
The radius is 5cm, which means that the diameter is 10cm.
The diameter of the Ferris wheel is 10cm.
If we recalculate the area again with the diameter given, we can see that:
AREA = 3.14r2
AREA = 3.14 x 5 squared ( radius is half diameter )
AREA = 3.14 x 25 = 78.5

3. Suppose that you are going to select a random sample of students from your school, measure the heights of the students in your sample, and then find the mean height for your sample. There are many different sets of students who could end up forming your sample. Will the sample mean be the same for all possible samples? If so, explain why. If not, what is the phrase used for the fact the sample means will vary according to the sample selected?
4. Return to the context of the previous item. The sample mean will vary according to what sample you happen to select. If you want to reduce this variation, would you choose to select a sample of size 5 or a sample of size 25?
Answers
Answer:
3: No
4: 25
Step-by-step explanation:
3: It won't because not everyone is the same height and there will be variation in the mean height.
4: A larger sample size will give a more accurate representation of the population, where as a sample size of 5 is much more likely to have a higher percentage of outliers, and each outlier matters much more in finding the mean. In a sample size of 25, each outlier matters much less.

Step 2 :
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?
To find out, we try dividing it by 2...
Nope! So now we try the next greatest prime number, 3...
No good. 3 is larger than 2. So we're done reducing.
