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

.33
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

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
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.

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

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

Find the critical value zc necessary to form a confidence interval at the level of confidence shown below. c=0.80
Answers

Step-by-step explanation:
Given a confidence (c) = 0.80
α = 1 - c = 1 - 0.8 = 0.2
α/2 = 0.2/2 = 0.1
From the normal distribution table, The critical value necessary to form a confidence interval is gotten by getting the z value of α/2, which is the same as that of 0.4 (0.5 - 0.1). The z value of α/2 is:

Tn = 2 + 3n-3
Tn = 3n-1

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
