Bob wants to buy a car. He puts $8,000 in a savings account that has a

A-$960

B-8,960

C-7,040

D-$320

Answers

9514 1404 393

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

If X = 9 units, Y = 7 units, Z = 18 units, and h = 8 units, what is the surface area of the triangular prism shown above?

Answers

Answer: 506 square units (answer choice B)

Step-by-step explanation:

The formula for the surface area of a triangular prism is:

SA = bh + 2ls + lb,

where b is the base, h is the height, l is the length, and s is the side of the triangle.

In this case, the base is 7 (Y), the height is 8 (h), the length is 18 (Z), and the side of the triangle is 9 (X).

So, by subsituition, we have:

SA = (7)(8) + 2(18)(9) + (18)(7)

SA = 56 + 324 + 126

SA = 506

The surface area is 506 square units.

Alvin is 7 years younger than Elgas. The sum of their ages is 63. What is Elgas age?

Answers

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.

Answers

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!

Step-by-step explanation:

The length of side b in triangle 2 is 36.

What are similar triangles?

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.

Answers

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].
