Step-by-step explanation:

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

The product is the answer when you multiply two numbers together. So, since Hasni is 4 years older than Alia, we need to find two numbers that are 4 apart that make 32 when we multiply them.

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 ages

First, 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.

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

Step-by-step explanation:

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?

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.

168 centimeters squared

190 centimeters squared

238 centimeters squared

250 centimeters squared

Answers

Answer:

238 cm squared.

Step-by-step explanation:

First do (5 x 14). Divide that by 2.

Then multiply 14 x 12.

Repeat step 1 for the opposite side, (5x14)/2.

Add your totals, 35+168+35=238.

Your answer is 238 cm squared.

I got 238 just multiply 12 and 14 then add 70 because (14 x 5 divided by 2 ) x 2

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!!

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.

Every triangle has a total of 180 degrees

Answer:

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.

In the graph, the highest or lowest point of a parabola is the vertex. The vertex of the graph of y=x2 is (0,0). If a>0 in f(x)=ax2+bx+c, the parabola opens upward. In this case the vertex is the minimum, or lowest point, of the parabola. so the vertex and the equations will lead to finding a parabola.

Answers

Answer:

Step-by-step explanation:

6/9 - 4/9 = 2/9

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!

describe a sequence of transformations that maps figure a to figure b

Answers

Answer:

rotate CCW 90°dilate by a factor of 2

Step-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 origin

These 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°
