Answer:

[tex]\frac{2}{8} <\frac{3}{4}[/tex]

Step-by-step explanation:

[tex]\frac{3}{4} =\frac{6}{8} \\[/tex]

therefore 3/4 will be greater than 2/8

Answer:

C) 4

Step-by-step explanation:

1 + x/2 = 3

x/2 = 2

x = 4

The value of x is 4.

Start with 4. Half of 4 is 2. Add 1. You get 3. 4 makes the problem work, so 4 is the answer.

Answer:

x=40

Step-by-step explanation:

The measure of the angle <RTS is half the difference of the measures of the intercepted arcs (mRS and mQP).

<RTS=(1/2)(mQP-mRS)

(x/2)=(1/2)((x+70)-(x+30))

x=x+70-x-30

x=40

Answer:

 [tex]a_n=a+(n-1)d[/tex]

Step-by-step explanation:

The given sequence is 22, 20, 18, ...

We need to find the explicit formula for an.

First term is 22

Second term = 20

Third term = 18

We can write the formula as :

[tex]a_n=a+(n-1)d[/tex]

Where

a is 22

d is common difference = 20-22 = -2

Forth term will be :

[tex]a_4=22+(4-1)(-2)\\\\=22-6\\\\=16[/tex]

Hence, the formula is [tex]a_n=a+(n-1)d[/tex].

Answer:

113.1 cm²

Step-by-step explanation:

we are given the diameter of the circle (length is 12 cm), and the formula for the area of the circle, which is πr², where r is the radius

so first, we need to find the radius

the length of the radius is half the length of the diameter

so that means that r=d/2

r=d/2

r=12/2

r=6

therefore the length of the radius is 6

now square 6, which is the same as multiplying it by itself

6²=36

now, multiply the radius squared by π, which is often substituted for as 3.14 or 22/7  

so if we were to do 22/7 for instance,

36*22/7≈113.14

round that to 113.1

there's your answer :)

Hope this helps!

Answer:

Arithmetic, add 3 each time

Answer:

I think it would be Malia but if I'm wrong please let me know.

Answer:

B (range)

Step-by-step explanation:

The IQR would actually increase, because the Q1, Q2, and Q3 would get most likely larger. (Or possibly stay the same).

The median would most likely increase, possibly stay the same.

The maximu would stay the same.

The range would decrease, because right now it’s 13, so without the outlier, the minimum value would be closer to the rest of the data.

Answer:

Elgas is 35.

Step-by-step explanation:

Let's set up an equation.

Alvin is 7 years younger than Elgas.

A = E - 7

The sum of their ages is 63.

A + E = 63

Let's use substitution.

Plug in the first equation of A into the second equation.

A + E = 63

(E - 7) + E = 63

Combine like terms.

2E - 7 = 63

Add 7 to both sides.

2E = 70

Divide both sides by 2.

E = 35

Elgas is 35.

Hope this helps!

Answer: 54 cm^2

Step-by-step explanation:

Answer:

36 would be the answer

Step-by-step explanation:

The length of side b in triangle 2 is 36.

Two triangles are similar if they have the same corresponding angles and their corresponding sides are in equal ratios.

Given that, there are two triangles, triangle 2 is a scale drawing of triangle 1.

Therefore, Δ 1~Δ 2,

According to the definition of similar triangles,

6/27 = 10/45 = 8/b

Therefore,

8/b = 6/27

8/b = 2/9

b = 36

Hence, the length of side b in triangle 2 is 36.

Answer:

  B.  $8,960

Step-by-step explanation:

Use your number sense.

If the account earns interest, the balance will increase from the initial deposit of $8000. The only sensible answer choice is B, $8960.

__

If you want to actually figure it out, the balance is given by ...

  A = P(1 +rt)

  A = 8000(1 +0.04·3) = 8000(1.12) = 8960 . . . . matches choice B
