Step-by-step explanation:

Hope this helps

Answer:

0.80 and 1.30

Step-by-step explanation:

0.80, 1.05, 1.30, 1.55, 1.80, 2.05

... + 0.25 = 1.05

= 1.05 - 0.25

= 0.80

0.80 + 0.25 = 1.05

1.05 + 0.25 = 1.30

1.30 + 0.25 = 1.55

1.55 + 0.25 = 1.80

1.80 + 0.25 = 2.05

10x + 38
40 + 7x
determine the value of x

Answers

Answer:

x= 2/3

Step-by-step explanation:

if they are equating,

10x +38 = 40+7x

10x-7x = 40-38

3x = 2

x= 2/3

Answer:

x = 0.6666666667

Step-by-step explanation:

Simplifying

10x + 38 = 40 + 7x

Reorder the terms:

38 + 10x = 40 + 7x

Solving

38 + 10x = 40 + 7x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-7x' to each side of the equation.

38 + 10x + -7x = 40 + 7x + -7x

Combine like terms: 10x + -7x = 3x

38 + 3x = 40 + 7x + -7x

Combine like terms: 7x + -7x = 0

38 + 3x = 40 + 0

38 + 3x = 40

Add '-38' to each side of the equation.

38 + -38 + 3x = 40 + -38

Combine like terms: 38 + -38 = 0

0 + 3x = 40 + -38

3x = 40 + -38

Combine like terms: 40 + -38 = 2

3x = 2

Divide each side by '3'.

x = 0.6666666667

Simplifying

x = 0.6666666667

Slope intercept

Answers

Answer:

the slope is 2/7 and the intercept is 4

Step-by-step explanation:

In order to find slope, you use the equation delta y over delta x which is the equation, y2-y1/x2-x1.

In this case you plug in each point and get the equation, 2-4/-7-0 or 4-2/0+7.

Simplify to get 2/7.

To find the intercept, you must see what's the y value when x is 0. In this case it's already given to you, so y intercept is 4.

13.) The leading scorer in your high school's hockey league finished the season with an average of 4 goals per game for 15 games. As the leagues
second leading scorer, you have an average of 4 goals per game for 14 games. You still have to play your last game. How many goals must you
score in the final game to overtake the leagues' leading scorer?

Answers

Answer:

5 goals

Step-by-step explanation:

4 goals per game for 15 games means a total of 60 goals in that season. You have 4 goals per game for 14 games meaning you have a total of 56 goals. To overtake the leading team you must score a minimum of 5 goals to become the leading scorer. (Double-check to make sure I am correct)

Step-by-step explanation:

There are 376 students in 8th grade at Samuel's school. There are 47 8th graders trying out for football last Thursday.

The number is students not trying out for football last Thursday is calculated as:

376 students - 47 students

= 329 students

The percent of 8th graders that did not try out for football is calculated as:

329 students/376 students × 100

= 329/376 × 100

= 87.5 %

Answers

Answer:

115, A

Step-by-step explanation:

The formula to find the total interior angles is   ([number of sides] - 2) x 180, so in this case it would be  540, and     if you subtract all the other interior angles you wi ll get y! (90,135,112,and  88)    (please excuse therandom spaces my spacebar isbroken)

The value of y from the figure is 115 degrees

Polygons

The given polygon is a pentagon

The sum of an interior angle of the pentagon is 540 degrees

Taking the sum and equating to 540 will give:

90 + 135 + 112 + y + 88 = 540

y + 425 = 540

y = 540 - 425

y = 115 degres

Hence the value of y from the figure is 115 degrees

By decomposing the design into two rectangular prisms, the surface area of the design is calculated as: A. 256 in.²

What is the Surface Area of a Rectangular Prism?

The surface area of a rectangular prism is expressed as, S = 2(lw + lh + wh).

The design can be decomposed into top rectangular prism and bottom rectangular prism.

The surface area of the design = surface area of the top rectangular prism + surface area of the bottom rectangular prism - 2(area of the top rectangular prism that joins the bottom rectangular prism)

Surface area of the top rectangular prism = 2(lw + lh + wh) = 2(5×4 + 5×4 + 4×4) = 112 in.²

Surface area of the bottom rectangular prism = 2(lw + lh + wh) = 2(8×5 + 8×4 + 5×4) = 184 in.²

Area of the top rectangular prism that joins the bottom rectangular prism = l × w = 5 × 4 = 20 in.²

The surface area of the design = 112 + 184 - 2(20) = 256 in.²
