The product of ages of Hasni and Alia is 32 years. Hasni is 4 years older than Alia. How old are Hasni and Alia?
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.

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

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.

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°
What is the value of x?
Answer:
56
Step-by-step explanation:
The angles of a triangle add up to 180 degrees. In this case, we have 2 values.
First, we add the two values that we already have so 91 + 33 = 124
To find the length of the missing angle, we subtract 124 from 180.
180 - 124 = 56
And 56 is the value of x.

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.

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!
