Name the polygon. Then tell whether it is a regular polygon or not a regular polygon.

Answer:

What is the question?

Step-by-step explanation:

Answer:

I think the answers would be a d and b

Step-by-step explanation:

the perimeter formula for a rectangle is 2L + 2W

if we take the measurements for rectangle a and add 4 + 4, we get 8. then we can do 2 + 2 to get 4. lastly, we would add 8 + 4, which equals 12.

for rectangle d, we can do 3 + 3, which equals 6. because the measurements are the same on each side, we don't have to do another equation and we would just add 6 + 6 to get 12.

and for rectangle b, you can do 1 + 1 = 2 and 5 + 5 = 10, then add 10 and 2 together to get 12.

Answer:

The answer would be 6.

Step-by-step explanation:

First, we need to make equations for these electricians fee's.

Electrician one: Y=25x+50, 50 is the upfront cost and 25 is the cost per hour for work.

Electrician two: Y=27.50x+35, It is the same thing for these numbers.

Then you need to incert numbers into the X place. Y will be your answer.

Y=25(6)+50, Y=150+50, Y=200

Y=27.50(6)=35, Y=165+35, Y=200

The answer would be 6. If both the electricians worked for 6 hours each, their prices would be equal.

Answer:

20km

Step-by-step explanation:

we need to find c, which is the hypotenuse of the right triangle.

we know the lengths of the legs, which are given as 16km and 12km

you might notice that 16km and 12km can both be divided by 4, which will then give is 4 and 3.

3,4,5 is a pythagorean triple-(the sums of the squares of 3 and 4 is equal to the square of 5).

The triple can be proved:

3²+4²=5²

9+16=25

25=25

that means the lengths of the triangle is a multiple of the triple 3, 4, and 5

so that means that c is 5*something

since 12 and 16 are 3*4 and 4*4 respectively, that means that c must be 5*4=20km

Hope this helps!

Answer:

D) 312 square cm

Step-by-step explanation:

The area of the rectangle is 192 square cm (16*12). The area of each triangle is 60 square cm (12*10/2). 192+60+60=312 square cm

Answer:

you got it right

Step-by-step explanation:

Answer:

f(3) = - 38

Step-by-step explanation:

f(2) = 3 f(2 - 1) - 5 = 3 f(1) - 5 = 3(-2) - 5 = -6 - 5 = -11

f(3) = 3 f(3 - 1) - 5 = 3 f(2) - 5 = 3(-11) - 5 = - 33 - 5 = - 38

Answer:

First some theory we need to solve this problem.

For a circle of radius R, the perimeter is:

P = 2*pi*R

where pi = 3.14

If we have a section of this circle, defined by an angle θ, the length of this arc will be:

A = (θ/360°)*2*pi*R

In the case of the problem, the total distance that the child travels is equal to the length of an arc of 310° in a circle of radius r = 6ft.

Using the above formula, we know that the length of this arc is:

A = (310°/360°)*2*3.14*(6ft) = 32.4 ft

Answer:

3750 apples

Step-by-step explanation:

Prob (Apple AAA rating) = AAA rated apples / Total Apples

25 / 330 = 0.075

Expected apples rated AAA from 50000 apples = P(AAA rating) x Apples no.

0.075 x 50000

3750  

Answer:

60%

Step-by-step explanation:

Have a nice day!

Answer:

∡b = 53°

∡d = 127°

∡c = 127°

Step-by-step explanation:

in trapezoids, the two top angles are equal and the two bottom are equal

also, there are 360 degrees in any 4-sided polygon

53 + 53 + x + x = 360

2x + 106 = 360

2x = 254

x = 127

Answer:

127

x ≥ -80

Answer:

Ummm give me a second let me solve this

The answer is 1/10

This is simple division

The equation is (1/5÷2)

I did my work on a sheet of paper so i know i did this correctly

My explanation of my work:

Keep change flip is the operation used here

So you keep 1/5 ,change the division sign to multiplication and flip the 2/1 into 1/2 so the new equation is (1/5x1/2) the answer to that is 1/10  

Have an amazing day :)

Answer:

2:6

Step-by-step explanation:

The question asks for the ratio of ladybugs to total insects. We'll use "l" for ladybugs and "i" for insects. So, the ratio will be l:i.

The number of ladybugs is 2, so we can plug that into our ratio.

2:i

Now, plug in the total number of insects, which is 6.

2:6
