Darnell bought 6 packs of baseball card. There were 6 cards in each pack Darnell put all his card in card book. He put 9 cards on each page.
How many pages of the card book did Darnell use?
Answer:
Darnell used 4 pages.
Step-by-step explanation:
We know Darnell has 36 cards, with this given we can do the simple division of 36 / 9 to get the answer of 4.
Pls give brainliest!
Answer:
4 pages
Step-by-step explanation:
1 pack : 6 cards
6 packs : x cards.
x = 6 x 6
= 36
Darnell bought 36 baseball cards.
1 page : 9 cards
x pages : 36 cards
x = 36/9
= 4
Darnell used 4 pages of his card book.

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.
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

A man usually rides his bike 9 kilometers per hour, yet the wind slows him to 6.76 kilometers for 26 minutes and 5.55 kilometers for 10, how long until he gets home 11.54 kilometers away?
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!!
Answer:
0
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.

Answer:
Swewed left
Step-by-step explanation:
I know this because most of the data is on the left and not many on the right. And in the graph the mean is less than the median so by that you can know it's left skewed because left skewed is also known as negative sweked and I use that to help me since less and negative have a link.

Subtract the following fractions. Simplify and reduce to the lowest terms.
6/9 - 4/9
A.10/9
B.2/9
C.1/3
D.10/18
Answer:
B
Step-by-step explanation:
6/9 - 4/9 = 2/9
Cant be simplified any farther
Answer:
The answer is B
Step-by-step explanation:
Step 1 :
Since our denominators match, we can subtract the numerators.
6 − 4 = 2
So the answer is:
2/9
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.
There you have it! The final answer is:
2/9!
Answer the two questions below
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?
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.

A Ferris wheel rotates three times when it travels 235.5 feet. Find the diameter of the Ferris wheel. Use 3.14 for pi
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

describe a sequence of transformations that maps figure a to figure b
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
rotate CCW 90°

Answer:
Bro i dont know if i am right but here we go
The answer most likely is 80
Step-by-step explanation:
By useing a bit of geometry instead of useing two angles to find your last angle.
So first notice how there are two of the same sides (14)but one differnt side(18) okay nice
With that info it is clear that it is a isosoles triangle (triangle with two equal sides and angles) so from that information two of the angles are gonna be the same. Luckely you were given an angle.
So that means there are two 50 angels and an X angle and to solve for X angle you need to add 50 + 50 = 100 then subtract to 180 then boom 80
I hope you understand and im sorry if this is wrong.
