Answers

Answer:

4.07

Step-by-step explanation:

11 1/5 divided by 2 3/4

= 11 1/5 ÷ 2 3/4

= 56/5 ÷ 11/4

= 56/5 × 4/11

= (56*4) / (5*11)

= 224/55

= 4.07

The best estimate of 11 1/5 divided by 2 3/4 is 4.07

$3000 is invested for a period of 3 years at a rate of 6% compound monthly. What will the balance in the account be at the end of 3 years?

Answers

Answer:

Hence, the total amount of money that the investor would have after 6 years will be $ 536.04 .

Step-by-step explanation

Answer:

Interest = $3573.048

Step-by-step explanation:

Given: $3000 is invested for a period of 3 years at a rate of 6% compound monthly. What will the balance in the account be at the end of 3 years?

The formula to compound interest is:

I = P(1 + R)^T

First, put in the terms:

I = $3000(1 + 6%)^3

Then calculate:

I = $3000(1 + [tex]\frac{6}{100}[/tex])^3

I = $3000(1 + 0.06)^3

I = $3000(1.06)^3, 1.06^3 = 1.191016

I = $3000 x 1.191016

I = $3573.048

Work out the volume of this prism. Write your answer
a in cm?
120cm
30cm
20 cm

Answers

Answer:

24,000 cm³

Step-by-step explanation:

Answer:

V = 48000 cm³

Step-by-step explanation:

The volume (V) of the prism is calculated as

V = area of end face × length

The end face is a trapezium with area (A) calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 20 , b₁ = 10 and b₂ = 30 , then

A = [tex]\frac{1}{2}[/tex] × 20 × (10 + 30) = 10 × 40 = 400 cm²

Thus

V = 400 × 120 = 48000 cm³

A wall is 15 ft. High and 10 ft. From a house. Find the length of the shortest ladder which will just touch the top of the wall and reach a window 20.5 ft. Above the ground.

Answers

Answer:

the length of the shortest ladder is 11.41 feet

Step-by-step explanation:

The computation of the length of the shortest ladder is shown below:

AB^2 = AC^2 + BC^2

AB^2= (10)^2 + (5.5)^2

AB^2= 100 + 30.25

AB^2 = 130.25

AB = 11.41 feet

hence, the length of the shortest ladder is 11.41 feet

Factor the equation. [tex]x^2+12x+35[/tex]

Answers

Answer:

(x + 7)(x + 5)

Step-by-step explanation:

Given

x² + 12x + 35

Consider the factors of the constant term (+ 35) which sum to give the coefficient of the x- term (+ 12)

The factors are + 7 and + 5 , since

7 × 5 = + 35 and sum = 7 + 5 = + 12, then

x² + 12x + 35 = (x + 7)(x + 5) ← in factored form

Six of the nine students are from Middle Georgia State College. What is the probability that both of the interviewed students are from Middle Georgia State College? Express your answer as a reduced fraction or decimal rounded to at least four decimal places.

Answers

Answer: 5/12

Step-by-step explanation:

Six of the nine students are from Middle Georgia State College.

The probability that the first student that's interviewed is from Middle Georgia State College will be 6/9.

Now, when the second student is picked, there'll be 8 students left out of which 5 will be from Middle Georgia State College. Therefore, the probability of choosing someone from there is 5/8.

Now, the probability that both of the interviewed students are from Middle Georgia State College will be:

= 6/9 × 5/8

= 2/3 × 5/8

= 10 / 24

= 5/12

Is a triangle with sides 4, 6, and 8 a right triangle? Explain your thinking.

Answers

Answer:

No it's not

Step-by-step explanation:

In a right triangle the longest side is always the Hypotnuse. With legs a and b and Hypotnuse c, all right triangle follow the Pythagoream Theorem (a^2+b^2=c^2)

If this is a right triangle then it should also follow this rule.

8^2=4^2+6^2

64=16+36

64≠52

So this isn't a right triangle

We can find the solution to the answer by using the Pythagorean Theorem.

a² + b² = c²

4² + 6² = 8²

16 + 36 = 52

8² = 64

52 ≠ 64.

Since 4² + 6² does not equal 8², a triangle with the sides 4, 6, and 8, are not a right triangle.

A farmer estimated that there were 25 gallons of water left in a tank. if this is an underestimate by 16%, how much was actually in the tank?

Answers

answer:

29 gallons.

explanation:

to find the percent of a number, you must multiply that number by the prevent in the form of a decimal. i.e 16% =0.16

25 * 0.16 =4

25 + 4 = 29

you add the 4 because that is 16% of 25 and you’re adding it because there were more gallons than estimated.

Answer:

La²+8La+16 = La²+70

Step-by-step explanation:

8La+16 = 70

8La=70-16

La=54/8

La= 6.75

Area b = (6.75+4)*(6.75+4)

Area b = 10.75*10.75

Area b =115.563

The area of a square is the square of its side lengths

The area of square B is 116 centimeter square

Let the side length of square A be (a), and the side length of square B be (b)

So, we have:

[tex]\mathbf{A_a = a^2}[/tex]

[tex]\mathbf{A_b = b^2}[/tex]

From the question, we have:

[tex]\mathbf{A_b = 70 + a^2}[/tex]

[tex]\mathbf{b = 4 + a}[/tex]

Take square of both sides

[tex]\mathbf{b^2 = (4 + a)^2}[/tex]

[tex]\mathbf{b^2 = 16 + 8a+ a^2}[/tex]

Substitute [tex]\mathbf{b^2 = 16 + 8a+ a^2}[/tex] in [tex]\mathbf{A_b = b^2}[/tex]

[tex]\mathbf{A_b = 16 + 8a+ a^2}[/tex]

So, we have:

[tex]\mathbf{16 + 8a+ a^2 = 70 + a^2}[/tex]

Subtract a^2 from both sides

[tex]\mathbf{16 + 8a = 70}\\[/tex]

Subtract 16 from both sides

[tex]\mathbf{8a = 54}[/tex]

Divide both sides by 8

[tex]\mathbf{a = 6.75}[/tex]

Recall that:

[tex]\mathbf{A_b = 70 + a^2}[/tex]

So, we have:

[tex]\mathbf{A_b = 70 + 6.75^2}[/tex]

[tex]\mathbf{A_b = 115.5625}[/tex]

Approximate

[tex]\mathbf{A_b = 116}[/tex]

Hence, the area of square B is 116 centimeter square
