Find the distance between points(-8,-2), (8,3)

Answer:

total cost = $130 + $35n

Step-by-step explanation:

Cost incurred on the first day.

Fixed cost = $40. this amount is fixed because it does not depend on the number of students that take the trip

variable cost = $19n. It is variable because it depends on the number of students that take the trip. the more the club members that take the trip, the higher the cost

Total cost on the first day = $40 + $19n

Cost incurred on the second day

Fixed cost = $90. this amount is fixed because it does not depend on the number of students that take the trip

variable cost = $16n. It is variable because it depends on the number of students that take the trip. the more the club members that take the trip, the higher the cost

Total cost on the second day = $90 + $16n

Total cost incurred would be the sum of the two costs incurred on the two days

total cost = $40 + $19n + $90 + $16n

= $130 + $35n

Step-by-step explanation:

Pete has already completed 27 missions. Pete plans to complete 3 missions per week

Let x represents weeks

Games completed = 3x + 27

Sophie has only completed 13 missions. Sophie plans to complete 5 missions per week.

Games completed = 5x + 13

3x + 27 = 5x + 13

27 - 13 = 5x - 3x

2x = 14

x = 7

By the seventh week, they would have completed equal number of games,

Answer:

90

Step-by-step explanation:

120 - (120/4)

120 - 30 = 90

Answer:

The first step to dividing fractions is to find the reciprocal (reverse the numerator and denominator) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. Finally, simplify the fractions if needed.

Answer:

b = 73

c = 34

Step-by-step explanation:

<T and <R are equal because they are opposite equal sides.

So b = 73°

Every triangle has 180 degrees

b + c + 73 = 180

73 + c + 73 = 180

146 + c = 180

c = 180 - 146

c = 34

The image of the right rectangular prism is missing, so i have attached it.

Answer:

volume of the right rectangular prism = 625 in³

Step-by-step explanation:

The rectangular prism is made of equal-sized cubes. Thus, let's first find the volume of 1 cube.

Formula for volume of one cube is;

V = a³

where

a is the length of one side of the cube

We are told that this length is 2½ inches

Thus;

a = 2½ = 5/2 inches

>> V = (5/2)³

>> V = 125/8 in³

Now, in the rectangular prism attached, if we count the number of cubes we have, it is equal to 40 cubes

Therefore, the volume of the prism is;

Volume of one cube × 40

>> volume of the prism = (125/8) × 40

volume of the prism = 625 in³

Answer:

$53,500 is the answer.

Step-by-step explanation:

The question is an Arithmetic Progression of common difference (d) = 700

a₁ = $50,000

a₂ = $50,700

d = $700

sixth year can be written as,

a₆ = a + 5d

a₆ = 50,000 + 5 × 700

a₆ = 50,000 + 3,500

a₆ = 53,500

therefore, Alberto will earn $53,500 in his sixth year of employment.

His salery grows by 700 per year, as you can see. This can be represented as [tex]700x+50000[/tex], where 50,000 represents the starting wage, 700 represents the annual increase, and [tex]x[/tex] represents the year (starting from 0). So, if you want to know his wage in his sixth year of employment, simply substitute 5 for [tex]x[/tex]. Note that [tex]x[/tex] is the number of years minus one. As a result, the answer is [tex]700(5)+50000=53500[/tex].

Answer:

S =4.9t²

Step-by-step explanation:

Using the equation of motion

S =ut+1/2gt²

u is the initial speed = 0m/s

t is the time

g I the acceleration due to gravity = 9.8m/s²

S is the distance of the object

Substitute

S = 0(t)+1/2 (9.8)t²

S = 0+4.9t²

S = 4.9t²

Hence thee equation that describes the distance an object falls from rest under the influence of gravity is S = 4.9t²

Answer:

Infinitely many solutions

Step-by-step explanation:

3x+y=1

15x+5y=5

Step: Solve3x+y=1 for y:

3x + y +−3 x = 1 + −3x (Add -3x to both sides)

y=−3x+1

Step: Substitute−3x+1 for y in 15x+5y=5:

15x+5y=5

15x+5(−3x+1)=5

5=5(Simplify both sides of the equation)

5+−5=5+−5(Add -5 to both sides)

0=0

so there are infinite solutions

I think it's a because

12÷42= 3.5

and

56÷16=3.5

so

10×3.5=35

Answer:

197in^2

Step-by-step explanation:

5x5=25(top face)

5x5=25(left face)

9x5=45(bottom face)

6.4x5=26(right face)

Front and behind face: trapezoid area (trapezoid formula h x (a+b)/2)

(5+9)/2 x 5=7x5=35

35+35+25+25+45+25=197in^2

Answer:

(180-102)/2 = 39° each (remaining 2)

Answer:

22√3 units squared

Step-by-step explanation:

1) Draw the trapezoid

2) Notice you have to find the height to find the area of the trapezoid

3) Notice it is a 30 60 90 triangle when you draw the line to find the height

4) Solve for the 30 60 90 triangle and you get the height to be 2√3

5) Solve for the area of the trapezoid using this formula A= 1/2 h ( b1 + b2)

6) Fill in the numbers for the equation A= 1/2∙ 2√3 ( 10 + 12)

7) Keep aside the 1/2 for now

8) Simplify equation 2√3 + 22 or 2√3 + (10 + 12)

9) Simplify further 44√3

10) Now bring back the 1/2 and put it in the equation 1/2∙ 44√3

11) Simplify to get 22√3

12) 22√3 is the area of the trapezoid

13) 22√3 units squared is the final answer

I will put a my drawing of the trapezoid for reference and this is what I used to solve the question.

If you want to know how I solved the 30 60 90 triangle please let me know.

Sorry I was one week late I just saw it today.

Answer:

The slope is -2

Step-by-step explanation:

Answer:

1: x = 29

2: Angle C is 93 degrees

Step-by-step explanation:

For 1 angle C has to equal 93 degrees since 52 + 35 = 87 and 180 - 87 = 93, and a triangles interior angles add up to 180 degrees.

From there create an equation: 3(x + 2) = 93 then solve

3x + 6 = 93

-6 from both sides

3x = 87

/3 from both sides

x = 29

For 2 just plug in x (29)

3(29 + 2)

87 + 6

93
