Step-by-step explanation:

multiply by 8 on both sides

Answer:

w = 163.84

Step-by-step explanation:

Rewrite the equation as w/8 = 20.48

w/8 = 20.48

Multiply both sides of the equation by 8

8 ⋅ w/8 = 8 ⋅ 20.48

Simplify both sides of the equation.

w = 163.84

1- You are designing a new popcorn box in the shape of a rectangular prism for the cinema theatres. The new popcorn box has a length of 7 inches, a width of 4 inches, and a height of 4 inches but does not include a lid.

Answers

Answer:

The surface area is 116 square inches

Step-by-step explanation:

Given

[tex]L = 7[/tex] -- Length

[tex]W = 4[/tex] -- Width

[tex]H = 4[/tex] -- Height

Required

Determine the surface area of the box [Missing from the question]

Since the box has no lid, the surface area is:

[tex]Area = 1\ bottom + 2\ fronts + 2\ sides[/tex]

[tex]Area = 7 * 4 + 2 * 7 * 4 + 2 * 4 * 4[/tex]

[tex]Area = 116[/tex]

work out the equation of the line which has a gradient of 2 and passes through the point (1,4).

Answers

Answer:

y = 2x + 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope (gradient) and c the y- intercept )

Here m = 2 , then

y = 2x + c ← is the partial equation

To find c substitute (1, 4) into the partial equation

4 = 2 + c ⇒ c = 4 - 2 = 2

y = 2x + 2 ← equation of line

You can slit it into two rectangles. On rectangle would have a area of 2x6 and another rectangle could have an area of 6x3. then you solve the area of the rectangles and add them for the total area. I have a picture of it:

Answer:

30 square feet

Step-by-step explanation:

1. Approach

Break up the given figure into two smaller rectangles. Calculate the area of those two rectangles, and then add up the results.

2. Rectangle 1

The is one extend the line with the measurement of (4ft), then one will get a rectangle with the dimensions of (6ft) and (3ft). Use the formula,

[tex]length * height = area[/tex]

Substitute;

6 * 3 = 18

3. Rectangle 2

The other rectangle that will result from this partitioning will have the dimensions (2ft) and (6ft). Again use the formula,

[tex]length * height = area[/tex]

Substitute,

2 * 6 = 12

3. Find the total area

Add up the area of these two smaller rectangles,

rectangle1 + rectangle2

= 18 + 12

= 30

Two vertices of a polygon are (7, −18) and (7, 18) .

Answers

Answer:

36

Step-by-step explanation:

Give the vertices of a polygon as (7, −18) and (7, 18) .

Length of the side is calculated using the formula;

L = √(x2-x1)²+(y2-y1)²

L = √(7-7)²+(18-(-18))²

L = √0+(36)²

L = √(36)²

L = 36

Hence the length of this side of the polygon is 36

Dale just bought 9 bags of 13 cookies each. He already had 6 cookies in a jar. How many cookies does Dale have now?

Answers

Answer:

123

Step-by-step explanation:

1 bag = 13 cookies

9 bags x 13 cookies = 117 cookies

117 cookies + 6 cookies that he already has = 123 cookies

Dale have 123 cookies in total.

Answer:

123 cookies.

Step-by-step explanation:

Multiply the amount of bags of cookies he bought, and the amount of cookies in each back to find out the amount of cookies he bought all together.

9 x 13 = 117

He already had six cookies saved. Add that the amount he had bought

117 + 6 = 123

Dale has 123 cookies in total.

10x + 20 = 180

10x + 20 - 20 = 180 - 20

10x = 160

10x ÷ 10 = 160 ÷ 10

X = 16

To measure the width of a river, you plant a stake on one side of the river, directly across from a boulder.

Answers

Answer:

514 m = width of the river to the nearest meter

Step-by-step explanation:

You must memorize the definitions of the trig functions and then these types of problems are easy.

You have a right triangle where the 100 m is the adjacent side to the 79° angle.  You are looking for the side opposite the 79° angle.  So, you need to use the tan function which is defined as opposite side/adjacent side

Let x = the length of the opposite side (width of river)

Tan 79 = x/100

100 tan 79 = x

x = 514 m = width of the river to the nearest meter

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. The width of the river is 514.455 meters.

What is Tangent (Tanθ)?

The tangent or tanθ in a right angle triangle is the ratio of its perpendicular to its base. it is given as,

[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}[/tex]

where,

θ is the angle,

Perpendicular is the side of the triangle opposite to the angle θ,

Base is the adjacent smaller side of the angle θ.


As it is given that you walk 100 meters to the right of the stake and measure a 79° angle between the stake and the boulder. Therefore, using the tangent angle the width of the river can be written as,

[tex]\rm Tangent(\theta) = \dfrac{Perpendicular}{Base}\\\\\\\rm tan(79^o) = \dfrac{\text{Width of the river}}{100\ meter}\\\\\\\text{Width of the river} = tan(79^o) \times 100 = 514.455\ meters[/tex]

Hence, the width of the river is 514.455 meters.

Answers

Answer:

Amount won = 590

X : ____ 590 ___ 0

P(X) : __ 1/50 __ 49/50

Expected payoff :

ΣX * p(x)

(590 * 1/50) + (0 * 49/50)

0.02 * 590 + 0
