Answers

Answer 1

Step-by-step explanation:

√a = 1√a so we can solve them easily:

b) 3√7 -√7= 3√7 - 1√7 =( 3-1)√7= 2√7

d) 5√6 - 2√6+√6= (5-2+1)√6 = 4√6

g) √2+2√2= 3√2

j) √5+5√5 - 3√5 = 3√5

k) 2√3 + √3 - 5√3= -2√3

I) 5√11 + 7√11 - √11 = 11√11

Mrs. Gonzalez bought a puzzle for $10.95, a board game for $15.95, and a table lamp for $17.10. After tax, the total amount due was $46.86. What is the sales tax rate written as a percent? Round to the nearest tenth if necessary.

Answers

Answer:

6.5%

Step-by-step explanation:

15.95+10.95+17.10 = 44

46.86-44 = 2.86

If x=47 , find the measures of angles 1,2 and 3

Answers

Angle x and 2 are congruent so angle 2 is also 47 degrees.

Angle x and angle 1 are supplementary so angle x and angle 1 adds up to 180 degrees.

180-47=133. Angle 1 is equal to 133.

Angle 1 and angle 3 are congruent as well so angle 3 is also 133 degrees.

Supposing you took out a $ 120,000 loan to go to med school. Your loan has a 6.9% APR to be paid in 30 years, and you make monthly payments of $ 790.32, and to date, you have made 180 payments, to determine what is the total amount you have left to pay if you simply make payments for the next 180 months the following calculation must be performed:

(120,000 x 1,069 ^ 30) - (790.32 x 180) = X (120,000 x 7.40) - 142,257.6 = X 888,203.34 - 142,257.6 = X 745,945.74 = X

Therefore, the total amount left to pay is $ 745,945.74.

A fair die is rolled 11 times. What is the probability of rolling a 4 on the die 4 times? Express your answer as a decimal rounded to 4 decimal places after the decimal point.

Answers

i think it’s 4/11

check out my other answers and mark me brainliest please !!!!

The probability of rolling a 4 on the die 4 times out of the total 11 times that it was rolled is; 0.0007716

How to solve probability?

We are given;

Number of times dice is rolled = 11

Now, on a die, there are 6 numbers and as such probability of getting a 4 is; P(getting a 4) = 1/6

Thus;

probability of rolling a 4 on the die 4 times = (1/6)⁴

⇒ 0.0007716

Step-by-step explanation:

f(0) = (0²+10·0+72)/(0²-12·0 + 36) Substitute 0 for x and solve.

= 72/36

= 2

f(5) = (5²+10·5+72)/(5²-12·5 + 36) Substitute 5 for x and solve.

Answers

To find the midpoint do, [(x1 + x2)/2], [(y1 + y2)/2]

5 + 1 = 6/2 = 3
-2 + -5 = -7/2 = -3.5

Answer:

(3, -3.5)

Step-by-step explanation:

Using midpoint formula:

M = (x1 + x2/2 , y1 + y2/2)

By inserting the points you'll find the answer:

M = (5 + 1/2 , -2 + -5/2)

M = (6/2 , -7/2)

M = (3 , -3.5)
