1. What is the sum of the measures of the interior angles of a 27-gon? (1 point)

Answer: b = 2

Step-by-step explanation:

[tex]b = \frac{2\sqrt{2}}{\sqrt{2} }\\b = 2[/tex]

Since this is a 45°-45°-90° triangle, the side opposite the 90° angle is √2× the other two angles. The other two angles are congruent since their opposite angles are both 45°.

Hope this helped! :p

Step-by-step explanation:

2[tex]\sqrt{2}[/tex] is the hypotenuse

The other 2 sides are equal to b since this is a 45-45-90 triangle meaning that it's isosceles

[tex]2b^{2}[/tex] = ([tex]2\sqrt{2}[/tex][tex])^{2}[/tex]

[tex]2b^{2}[/tex] = ([tex]\sqrt{8})^{2}[/tex]

[tex]2b^{2}[/tex] = 8

[tex]b^{2}[/tex] = 4

b= 2

Hope this helps!!!

Answer:

3/5 or 60%

Step-by-step explanation:

It looks like you filled in A correctly so I will focus on B

There are 24 cars in the pool and 16 vans totally 40 total vehicles

If were to pick a random vehicle from the pool the odds of it being a car is equal to

number of cars in the pool/number of vehicles in the pool

This means the odds of you randomly picking a car is 24/40 which simplifes

to 3/5

Answer:

21 bags are not full.

Step-by-step explanation:

Given that,

Total no. of marbles = 395

He is putting 22 marbles in each bags.

We need to find the number of marbles will he have in the bags that is not full. It can be calculated by dividing total no. of marbles and the no. of marbles in each bags.

[tex]x=\dfrac{395}{22}\\\\=17.95\\\\\text{or}\\\\=17\dfrac{21}{22}[/tex]

So, it means 17 bags are full but 21 bags are not full.

Answer:

a. x = 5, AB = 14, BC = 8

Step-by-step explanation:

✔️Both triangles are similar, therefore their side lengths are proportional to each other.

Thus:

[tex] \frac{2x + 4}{x + 3} = \frac{7}{4} [/tex]

Cross multiply

[tex] 4(2x + 4) = 7(x + 3) [/tex]

[tex] 8x + 16= 7x + 21 [/tex]

Collect like terms

[tex] 8x - 7x = -16 + 21 [/tex]

[tex] x = 5 [/tex]

✔️AB = 2x + 4

Plug in the value of x

AB = 2(5) + 4

AB = 14

✔️BC = x + 3

Plug in the value of x

BC = 5 + 3

BC = 8

Step-by-step explanation:

Hey there!

Given sequences are; 2 , 13 , 24 , 35 , _ , _ .

Now,

Common difference (d) = 2nd term - 1st term. = 13-2 = 11

When we subtract 1st term from 2nd term we find 11 and when we subtract 2nd term from 3rd term we get 11. This means our common difference is 11.

Now, let's find the nrh term of the sequence.

nth term= a1 + (n-1)d ( a1= 1st term, d= common difference)

nth = 2+ (n-1) 11

= 2 + 11n - 11

= 11n - 9

Let's check if we have got nth term correct.

a1= 1*11 - 9 = 2

a2 = 2*11-9 = 13

a3 = 3*11 - 9 = 24

a4 = 4*11-9 = 35

So, we got our nth term.

Let's find remaining sequence.

a5= 5*11 - 9 = 46.

a6= 6*11 - 9 = 57.

Therefore, the remaining terms are : 46 and 57.

Hope it helps...

2+11=13

13+11=24

24+11=35

35+11=46

46+11=47

Answer:

1: 86 inches is the width

2: -20

Step-by-step explanation:

Answer:

60

Step-by-step explanation:

-2 x 4 = -8

-2 x -2 = 4

-8 - (-4) = -4

(keep change flip)

-4 - -4(3) 4x4x4= -64

-4 - (-64)

60

Answer:

Remember the key word”factor” which means to multiply. Multiple all those numbers by 3!

Step-by-step explanation:I’m going to do 2 of them and you can do the last one (2,1)x3= the dilation (6,3). (3,0)x 3 gives the dilation (9,0). (1,-2)x3 gives the dilation of (3,-6). See it’s very easy.

Answer:

Option D

Step-by-step explanation:

Formula for the surface area of rectangular prism = 2(lb + bh + hl)

Here, l = Length of the prism

b = Width  

h = Height

If l = 25 cm, b = 12 cm and h = 20 cm

Surface area of the rectangular prism = 2(25×12 + 12×20 + 20×25) cm²

Therefore, Option D will be the correct option.

Answer:

x - 1 and 5x - 7

Step-by-step explanation:

f(x) + g(x)

= 3x - 4 - 2x + 3 ← collect like terms

= x - 1

f(x) - g(x)

= 3x - 4 - (- 2x + 3) ← distribute parenthesis by - 1

=  3x - 4 + 2x - 3 ← collect like terms

= 5x - 7

Answer:

[tex]\displaystyle f(x)=-\frac{1}{16}(4^x)[/tex]

Step-by-step explanation:

We have the function:

[tex]f(x)=-4^{x-2}[/tex]

And we want to convert this to the exponential form:

[tex]f(x)=ab^x[/tex]

First, using the power of a product property, we can rewrite our function as:

[tex]f(x)=-(4^x\cdot4^{-2})[/tex]

By evaluating the second term, we acquire:

[tex]\displaystyle f(x)=-\big(4^x\cdot \frac{1}{4}^2}\big)=-\big(4^x\cdot \frac{1}{16}\big)[/tex]

So, by rearranging, we acquire:

[tex]\displaystyle f(x)=-\frac{1}{16}(4^x)[/tex]

As desired.

Answer:

48:18:24 or ∠A = 48, ∠B = 18, ∠C = 24

Step-by-step explanation:

Since The angles of a triangle add up to 90, then 8 + 3 + 4 should equal to 90 if multiplied by x.

Example:

x(8 + 3 + 4) = 90

x(15) = 90

15/15x = 90/15

x = 6

If x is equal to 6, then 6 times 8, 6 times 3, and 6 times 4, should equal their respective angles and add up to 90.

Example:

8 * 6 = 48

3 * 6 = 18

4 * 6 = 24

48 + 24 + 18 = 90

This means the angles are

48:18:24 or ∠A = 48, ∠B = 18, ∠C = 24
