A right triangle has one angle that measures 69º. What is the measure of the other acute
angle?

Answers

Answer:

21°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

subtract the sum of the 2 given angles from 180 for the other angle

other angle = 180° - (90 + 69)° = 180° - 159° = 21°

You purchase a video game system for $150. You make a down payment of $25. You pay the rest of the money you owe in 5 equal monthly payments with no interest. How much is each monthly payment ?


Can you help me set the problem up too? thx

Answers

9514 1404 393

Answer:

  $25

Step-by-step explanation:

Let p represent the monthly payment. There are 5 of them, so the amount of their total is 5p. That, together with the down payment, makes up the entire cost of the system.

  5p +25 = 150 . . . . an equation representing the relationships

__

To solve this, subtract 25 and divide by 5.

  5p = 125

  p = 125/5 = 25

Each monthly payment is $25.

18(2 +2)
6(2+6)

Answers

Answer: 9(2+4)

Step-by-step explanation:

18 + 36 = 54

18(1+4) = 90

18(2+2) = 72

9(2 + 4) = 54

6(2+6) = 48

The best representation of the expression 18 + 36 after using distributive property is 18(1 + 2).

In circle M with m \angle LMN= 98m∠LMN=98 and LM=18LM=18 units, find the length of arc LN. Round to the nearest hundredth.

Answers

Answer:

To the nearest hundredth, this is 30.79 units

Step-by-step explanation:

To find the length of the arc, we simply apply the length of arc formula

Mathematically, that would be;

theta/360 * 2 * pi * r

Theta here is 98

r is 18 units

So the length of the arc will be;

98/360 * 2 * 22/7 * 18

= 30.7876 units

to the nearest hundredth, this is;

30.79 units

Please help:( i don't understand this question Kendall’s benchmark test scores are the following: 89, 79, and 93. She has to take her fourth and final benchmark on June 6 th . She really wants to get an A in the class and in order to do so she must have an average of a 90. If Kendall’s teacher decides to count the final exam as two test grades, what would she need on the final test to make sure she gets an A?

Answers

Hey there!

The answer to your question is 94.5

We can use this equation, and solve: (we need to use "2x" because the score counts for 2 grades!)

(89 + 79 + 93 + 2x) / 5 = 90

(261 + 2x) / 5 = 90

261 + 2x = 450

2x = 189

x = 94.5

To check if it's right, we can add up all the scores, and divide by 5, and see if it's equal to 90. (Make sure to use 94.5 twice because it counts for 2 test grades!)

(89 + 79 + 93 + 94.5 + 94.5) / 5

450 / 5

90 ✔️

Hope it helps! Have a great day and good luck!
