Answer:

  no

Step-by-step explanation:

The dimensions will be those of a rectangular mirror if the diagonal measure is the hypotenuse of the right triangle with the given side lengths.

The Pythagorean theorem would require for some width w ...

  w^2 +24^2 = 30^2

  w^2 = 900 -576 = 324

  w = √324 = 18

A rectangular mirror with a length of 24 inches and a diagonal of 30 inches will have a width of 18 inches, not 16.

__

The attachment shows that a width of 16 inches is not consistent with a right-angle corner.

Additional comment

If you reduce the given numbers to lowest terms by dividing them by 2, they become 8, 12, 15. That is, the two shortest sides are even and the longest is odd. Any set of integer dimensions for a right triangle must have an even number of odd numbers (0 or 2). These numbers cannot be a Pythagorean triple, so cannot make a right triangle.

Answer:

A: 4/5

Step-by-step explanation:

The equation for proportionality is y = kx, where k is the constant of proportionality. That is what you're looking for in this question.

So in y = 4/5x, 4/5 is the constant of proportionality/unit rate for the proportional relationship.

The 4/5 is the constant of proportionality/unit rate for the proportional relationship.

We have given that,

the unit rate for the proportional relationship is represented by the equation y=4/5x.

We have to determine the unit rate

The equation for proportionality is y = kx, where k is the constant of proportionality.

So in y = 4/5x,

The 4/5 is the constant of proportionality/unit rate for the proportional relationship.

Answer:

The surface area of the cylinder will be "131.88".

Step-by-step explanation:

The given values are:

Height of cylinder,

h = 4 m

Radius of cylinder,

Answer:$32.86

Step-by-step explanation:

multiply the percent (6%) by 31$ which will get you 1.86. that's the tax amount. so then you add that to $31 and get $32.86

Answer:

C. 32.86

Step-by-step explanation:

The equation to calculate how much the tax is

31 x 0.06

This equals 1.86

Now add the original price and the tax amount together.

31 + 1.86 = 32.86

Therefore, the answer is 32.86

Answer:

co interior angle plz take my and

Answer:

1) Alternate exterior

2) alternate interior

3) consecutive interior angles

Alright so here’s a trick

Alternate already means different sides so look for that.

Interior angles are all the angles inside the two parllel lines.

Exterior angles are all angles out side the two parralel lines.

No matter what if its alternative interior or exterior, it should make a perfect

“/“ or back slash.

Consecutive is on the same side.

Corresponing is also on the same side but it has 1 exterior and 1 interior

Answer:

x=24

Step-by-step explanation:

there are different ways to solve the problem

set up a proportion:

16/(2/3)=x/1

cross multiply

(2/3)x=16

(3/2)(2/3)x=(3/2)(16)

x=24 square feet per hour

a carpenter lays 16 square feet in 40 minutes (2/3 of an hour)

this means he lays 4 square feet every 10 minutes

8 square feet in 20 minutes

12 square feet in 30 minutes

24 square feet in 60 minutes

Answer:

Quotient = a²+ 4a- 2

Step-by-step explanation:

(8a3+31a2-20a-5)/(8a-1)

 =

             a²  +4a-2     ⇒ quotient

(8a-1)√(8a3+31a2-20a-5)

              8a²- a²                  ⇒       Multiplying  (8a-1) by a²

             -     +        ⇒   Changing signs

                     32a²- 20a- 5                

                    32a²- 4a            ⇒   Multiplying  (8a-1) by 4a

                    -        +     ⇒Changing signs

                             -16a -5

                             - 16a +2          ⇒    Multiplying  (8a-1) by -2

                              +       -      ⇒  Changing signs

                                         -7  ⇒ Remainder

We follow the steps of simple division to get the quotient which is a²+ 4a- 2

We multiply  (8a-1) by factors such as a², +4a and -2 to get the same terms as given in the dividend.

Answer:29

Step-by-step explanation:

d[AB]=|45-16|=29

A number line is the representation of numbers in real order.

The difference between the consecutive numbers in a number line is always positive.

The length AB is 29.

AB = 29 is our answer.

It is the representation of numbers in real order.

The difference between the consecutive numbers in a number line is always positive.

We have,

A is at point 16.

B is at point 45.

Now,

The distance between A and B.

= B - A

= 45 - 16

= 29

Thus,

The length AB is 29.

AB = 29 is our answer.

Answer:

The correct answer is C. That problem best represent x - 15 =60.

Answer:

C

Step-by-step explanation:

So lets look at the first equation.

This would represent 60-15=x

This is because 60 shells minus 15 shells she gave away.

Next is B, whihc is also 60-15=x

This is because Mr yungs brother is 60 years old and mr yung is 15 years younger.

Next is c, whihc is 60+15=x

This is because they had 60, gave 15 already, and want to find out what they started with.

FInally we are left with d.

This is 15+x=60

Well...none of those look like x-15=60

But lets go back to c:

60+15=x

Lets try to rwwrite this.

Subtract 15 from both sides, and you get:

60=x-15

Just make this proper by putting the x-15 before the 60:

x-15=60

That looks like x-15=60

Now we know our answer!

C
