Question 20 of 40
Juan has scores of 85, 83, and 93 on three math
tests. What is Juan's average test score on these
math tests?
85

Answer:

The answer would be C, hope i helped

Step-by-step explanation:

First you have to get x by itself. So you do 90-90= 0 and 30-90= -60 which gets:

90 - 3/2x < 30       to     -3/2x < -60

Then, you do -3/2 - (-3/2)= 0 and do the same to -60. -60 - (-3/2) = -58.5

which makes it look like      

X = -58.5

-58.5 is a smaller number than -40 which means, when you fill it in for x it works      

-58.5 ≤ -40

Answer:

Ronnie spent 5 hours working.

Step-by-step explanation:

From the information given, the total cost of the job is equal to the flat fee plus the result of multiplying the cost per hour for the number of hours which is:

c=25+30x, where:

c is the total cost of the job

x is the number of hours

Now, you can replace c with 175 and solve for x:

175=25+30x

175-25=30x

150=30x

x=150/30

x=5

According to this, the answer is that Ronnie spent 5 hours working.

Answer:

7.5

Step-by-step explanation:

Ronnie charges $25 plus $20 per hour. This means that he made the following depending on how many hours he spent on it:

Hours        Dollars

0                 25 = 25 + 0(20)=25

1                  25+20 = 25 + 1(20)=45

2                  25+20+20 = 25 +2 (20)=65

3                  25+20+20+20 = 25 +3 (20)=85

4                  25+20+20+20+20 = 25 +4 (20)=105

5                  25+20+20+20+20+20 = 25 +5 (20)=125

......

n                  25+n(20)=175

To find how many hours he worked for $175 we solve the equation using inverse operations:

25+n(20)=175

25-25+n(20)=175-25

n(20)=150

n= 7.5 hours

Answer:

Slope: 0, y-intercept: -1

Step-by-step explanation:

If a line is completely horizontal, the slope is 0. The equation of this line is:

y = 0x - 1 = -1

The slope is 0 and the y-intercept is -1 because that is the y-coordinate this line intercepts with.

Hope this helps!

Answer:

Object A

Step-by-step explanation:

Usually for these kinds of questions you would look at the steepness of the slope, the steeper it is, the quicker/faster it is.

Answer:

28 band members

Step-by-step explanation:

Since 40% of the band members are sixth graders, we need to take 40% of 70 total students.

40% of 70 = 0.40*70 = 28

So 28 band members are in sixth grade

A or B think it's A tho not sure

Answer:

B. -4

Step-by-step explanation:

The slope is -8/2 which is the same as -4.

Another way you could do it is down 4 and right 1. That would be -4/1 which is the same as -4.

Answer:

Number of vans = 7 students

Number of buses = 60 students

Step-by-step explanation:

Let

Number of vans = x

Number of buses = y

2x + 11y = 674 (1)

6x + 14y = 882 (2)

Multiply (1) by 3

6x + 33y = 2,022 (3)

6x + 14y = 882 (2)

Subtract (2) from (3)

33y - 14y = 2,022 - 882

19y = 1,140

y = 1,140 / 19

= 60

y = 60 students

Substitute y = 60 into

2x + 11y = 674 (1)

2x + 11(60) = 674

2x + 660 = 674

2x = 674 - 660

2x = 14

x = 14/2

= 7

x = 7 students

Answer:

Step-by-step explanation:

1. a). Hypotenuse² = (Leg 1)² + (Leg 2)²

       h² = 10² + 24²

       h = √676

       h = 26

 (b). Hypotenuse² = (Leg 1)² + (Leg 2)²

       (25)² = (15)² + (leg 2)²

       Leg 2 = √(625 - 225)

                 = √400

                 = 20

  (c). Hypotenuse² = (Leg 1)² + (Leg 2)²

        h² = 4² + 6²

        h = √(16 + 36)

        h = √52

        h = 2√13

  (d). Hypotenuse² = (Leg 1)² + (Leg 2)²

        (14)² = (Leg 1)² + 7²

         Leg 1 = √(196 - 49)

                   = √147

                   = 7√3

2). Hypotenuse² = (Leg 1)² + (Leg 2)²

    Leg 1 = leg 2 = 7 units [Since, triangle is an isosceles triangle]

    h² = 7² + 7²

    h = √98

    h = 7√2

    Option (1) is the correct option.

3). Hypotenuse² = (Leg 1)² + (Leg 2)²

    (26)² = (Leg 1)² + (10)²

    Leg 1 = √(676 - 100) = 24

    Area of a right triangle = [tex]\frac{1}{2}(\text{Leg 1})(\text{Leg 2})[/tex]

                                           = [tex]\frac{1}{2}(24)(10)[/tex]

                                           = 120 square units

     Option (3) is the correct option.

Step-by-step explanation:

Segment RT bisects ∠QRS in ΔQRS and therefore, the angles ∠1 and ∠2

formed are equal.

The valid reason for the statement ∠1 ≅ ∠2 is; A. Definition of Angle Bisector.

Reasons:

The information on the triangle ΔQRS are;

The angle bisector of ∠QRS = RT

Therefore;

∠QRT = ∠1, ∠SRT = ∠2 Given in the diagram

∠QRS = ∠QRT + ∠SRT by angle addition property

∠QRT ≅ ∠SRT  by definition of angle bisector

∠1 ≅ ∠2 by definition of ∠QRT and ∠SRT

By substituting ∠QRT with ∠1 and ∠SRT with ∠2, we have;

∠1 ≅ ∠2 by definition of angle bisector

The valid reason for the statement is therefore; A. Definition of angle

bisector.
