Can someone please help me with this question

Answer:

1. AE= 312

2. AC = 161

Step-by-step explanation:

Hey there!

In order to solve the first question, we need to think of possible "C" values

Then after finding the "C" value, we can then find the "A" and "E" values

So:

AC = 24 and CE = 13

What factors do 24 and 13 have in common?

Well, only 1 since 13 is a prime number]

So this means that C has to be 1

Now we know that A is 24 and E is 13

Now we have to multiply them together

24 x 13 is 312

So AE= 312

Now we go on to the second question

We can use the same strategy we used for number one

Instead of finding what C is, we need to find out what E is, since there is E in both of the statements

So:

CE = 7 and AE = 23

What common factors do these two numbers have?

Again, only 1, meaning that E can only be 1

Now we know that C is 7 and A is 23

Since we know this, we can multiply these two numbers together and get our final answer: 161

So AC = 161

Quotient means we have to divide

Divide

or

9/C

Answer:

[tex]\sf \dfrac{9}{C}[/tex]

Step-by-step explanation:

A quotient is produced by dividing two numbers.

"The quotient of a and b" means "a divided by b".  So the first number "a" is the numerator, and the second number "b" is the denominator of a fraction.

Therefore, "the quotient of 9 and C" is:

[tex]\sf \dfrac{9}{C}[/tex]

Answer:

scale factor = 2.5

Step-by-step explanation:

the scale factor is the ratio of corresponding sides, polygon P to N

scale factor = [tex]\frac{20}{8}[/tex] = 2.5

Answer:

7.5 units

Step-by-step explanation:

since the y- coordinates of the points are equal, then the distance between them is the absolute value of the difference in the x- coordinates.

distance = | - 2.5 - 5 | = | - 7.5 | = 7.5

or

distance = | 5 - (- 2.5) | = | 5 + 2.5 | = | 7.5 | = 7.5

Answer:

0.179 is the answer yw btw tell me if it's right !!

From the z table the critical value corresponding to the level of significance level for a two-tailed test is z = 1.64.

There are two hypotheses. First one is called null hypothesis and it is chosen such that it predicts nullity or no change in a thing. It is usually the hypothesis against which we do the test.

The hypothesis which we put against the null hypothesis is an alternate hypothesis.

The null hypothesis is the one that researchers try to disprove.

From the question, we are told that

The number of observations is greater than 50  i.e. n > 50

The  level of significance is  [tex]\alpha = 0.1[/tex]

Generally given that n >  30  then we will make use of the z table

So From the z table the critical value corresponding to the level of significance level for a two-tailed test is z = 1.64.

Answer:

see explanation

Step-by-step explanation:

an arc of a circle is equal to the central angle subtended by the arc

central angle of arc ED = 50° ( vertically opposite angles )

then

arc ED = 50°

the central angle of arc BC = 180° - 40° - 50° = 180° - 90° = 90°

then

arc BC = 90°

the central angle subtended by arc AE = 180° - 50° = 130°

then arc AE = 130°

arc BED = arc BA + arc AE + arc ED = 50° + 130° + 50° = 230°

Answer:

K = 3D + 6

Step-by-step explanation:

Let Mr Kim's age be denoted by K and his daughter by D.

It states that :

Then the expression will be :

There were _22_ cars in the first train, _24_ cars in the second train, and _26_ cars in the third train

We know that the trains have 418, 456, and 494 seats. And are made of the same train cars, so the number of seats on each train car is a common factor of 418, 456 and 494.

We also know that no train car has more than 25 seats.

First, let's decompose the given numbers as a product of prime numbers:

418 = 2*11*19

456 = 2*2*2*3*19

494 = 2*13*19

As you can see, the factors 2 and 19 appear in the 3 numbers, 19 is the largest one that is also smaller than 25, so we conclude that each train car has 19 seats.

Then:

The first train, which has 418 seats, has:

418/19 = 22 train cars.

The second train has 456 seats, so it has:

456/19 = 24 train cars

The third train has 494 seats, so it has:

494/19 = 26 train cars.

Square C is comprised of the areas of squares A and B

It proves that this triangle is a right triangle

By adding the areas of two perfect squares, A and B, square C can only be the sum. This proves the Pythagorean Theorem to be true, as the ratios to the sides, and therefore the equation, will remain fixed in any scalene right triangle.
