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

-6h - 1

Step-by-step explanation:

-9 + (-10h) + 4h + 8

-9 + (-6h) + 8

-6h - 1

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.

Answer:

3 inches

Step-by-step explanation:

If the dog chews off 4 inches every day, you first have to multiply the inches by the number of days, which in this case is 3 x 4, which equals 12. In 3 days, he chewed off 12 of the original 15 inches, leaving only 3 inches left.

Answer:

The function  [tex]y= -x^{1/2}+5[/tex] has a domain of all real numbers.

Thus, option (D) is correct.

As, Domain is the input value of the function.

In the function [tex]y= -x^{1/2}+5[/tex] .

The square root is defined for all non-negative real numbers (including zero).

When we subtract this square root from 5, the resulting function has a domain of all real numbers.

In options A, B, and C, which involve fractional exponents or roots, option D does not have any restrictions on the values of x.

The function can be evaluated for any real number x, making its domain all real numbers.

Therefore, [tex]y= -x^{1/2}+5[/tex] , has a domain of all real numbers.

Answer:

x=-6

Step-by-step explanation:

Answer:

The Pythagorean Theorem can be used to find the length of the legs and hypotenuse of a triangle. While the distance of a vertical or horizontal line can be counted easily, a diagonal line cannot be determined the same way. A diagonal line, such as the line between the two points shown on the graph, is the hypotenuse of an imaginary right triangle. If you draw the legs of the triangle by drawing straight lines through the points on the graph until the lines meet at a point, you can count the distance of the legs and plug those values into the Pythagorean Theorem.

Step-by-step explanation:

In this case, the meeting point of straight lines drawn through the points is

(-3, -4)

and the distances of the legs of the right triangle are 8 and 6. The theorem is

a² + b² = c²

so 8² + 6² = c²    to 64 + 36 = c²    to 100 = c²    and [tex]\sqrt 100 = \sqrt c^{2}[/tex]

so 10 = c

The distance of the line (hypotenuse) is 10.

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.

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:153

Step-by-step explanation:

From the question, we are informed that Emilio asks his classmates what month they were born and that he finds that 15 out of 125 classmates were born in July. This gives us a fraction of 15/125 = 3/25.

If there are 1,280 students in Emilio's school, the number of students that he can expect to have birthdays in July would be:

= 3/25 × 1280

= 153.6

There will be 153 students expected

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.

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
