1. A student in an algebra course has test scores of 75, 82, 71, and 84. What score on the next test will raise the student’s average to 80?

Answers

Answer 1

Hey there! I'm happy to help!

We have 5 numbers that will give us an average score of 80.

75,82,71,84,x

What we do is add these all up and divide by 5 to get 80. Let's go backwards to find x.

We multiply by 5.

80(5)=400

We subtract all of the numbers except for x.

400-75-82-71-84=88

Therefore, the score on the next test has to be 88 to have the student's average be 80.

Have a wonderful day! :D

Answer:

∠BOC = 45

Step-by-step explanation:

∠BOC + ∠AOB = ∠AOC ----------eq.1

where:

∠AOC = 96

∠BOC = 8x - 67

∠AOB = 9x - 75

find:  ∠BOC

plugin values into the eq.1

∠BOC + ∠AOB = ∠AOC

8x - 67 + 9x - 75 = 96

8x + 9x - 67 - 75 = 96

17x = 96 + 67 + 75

17x = 238

x = 238 / 17

x = 14

plugin x into ∠BOC = 8x - 67

∠BOC = 8x - 67

∠BOC = 8(14) - 67

∠BOC = 45

angle BOC equals 45 degrees

How many zero arin the product of any whole. number less than 10 and 500

Answers

Answer:

Hay un máximo de tres ceros en el producto de un número distinto de cero cero menor que 10 y 500

Para poder ver esto, la forma más fácil para resolver este problema es multiplicar todos los números entre 1 y 9 por 500, es decir:

01*500 = 500

2*500 = 1.000

3*500 = 1.500

4*500 = 2.000

5*500 = 2.500

6*500 = 3.000

7*500 = 3.500

8*500 = 4.000

9*500 = 4.500

Como vemos, si multiplicamos a 500 por cualquier número par, entonces obtenemos un número con tres ceros, mientras que si este es impar solamente obtenemos dos ceros

Can someone teach me how to do this????

Answers

Answer:

x = 12

Step-by-step explanation:

For this problem it is important to note that the sum of the two unknown angles' measurements is equivalent to the given known angle measurement as implied by the drawing.  With this in mind let's write our givens:

m<CGF = 10x - 10

m<HGC = 3x + 10

m<HGF = 156

So now let's form our equation to represent the drawing:

m<CGF + m<HGC = m<HGF

And now let's solve the equation to find the value of the x.

m<CGF + m<HGC = m<HGF

( 10x - 10 ) + ( 3x + 10 ) = 156

10x - 10 + 3x + 10 = 156

13x = 156

x = 12

Hence, our value for x is 12.

Cheers.

Answers

Answer:

[tex]C= 40t+100[/tex]

Step-by-step explanation:

 In this exercise, we want to model an equation to represent the cost that Gabriel will when registering with a gym.

from the given information, we can model the cost after the equation of a straight line

y= mx+c

so "C" is the cost, while $40 is a fee dependent on "t" the number of months subscribed

and $100 is the joining fee, which is a constant term

1. Jim opens a savings account with $22,500. His account pays 3.5% simple interest. At the end of 5.5 years, Jim closes the account. How much interest does he earn? What is the total value of his account when he closes it?

Answers

Answer:

$27186.57

Step-by-step explanation:

Formula: start(interest)^time

First, we need to calculate the interest which in this case would be 1.035 (1+(3.5/100)) since it is increasing 3.5% each year. Then we can just plug the values into the formula to get:

22,500(1.035)^5.5 = 27186.57

Answers

Answer:

80

Step-by-step explanation:

Initial ratio:

Teachers to students

1 : 15

Ratio after:

Teachers to students

3 : 40

The number of students did not change, so we can make the students of the initial ratio and the students of the ratio after the same.

1 : 15 =  8 : 120

3 : 40 = 9 : 120

120 units = 1200

1 unit = [tex]\frac{1200}{120} =10[/tex]

Initial teachers = 8 units = [tex]8*10=80[/tex]

I think the answer is 80
