The amount of money Trevon had last Friday⇢$29

The total amount of money he has after cleaning the attic⇢$41

So,

The amount of money he received after cleaning the attic ⇢ Total money he has after cleaning the attic - The money he had last Friday

Thus ,he received $ 12 for cleaning up the attic.

The cost of the game ⇢$30.98

The amount of money she gave to the cashier ⇢$40

The amount she'll receive back⇢ the amount of money she gave to the cashier - the cost of the game

Hence , she'll receive $ 9.02 back from the cashier.

Answer:

Given:

To calculate the money Trevon received for cleaning the attic over the weekend, we need to find the difference between the money he started with and the money he now has.  To find the difference, subtract the smaller number from the bigger number:

⇒ Money Trevon received = Money he has now - money on Friday

                                             = $41 - $29

                                             = $12

Therefore, Trevon received $12 for cleaning the attic over the weekend.

Given:

To calculate the change Jenny received from the cashier, we need to find the difference between the two amounts.  To find the difference, subtract the cost of the game from the money Jenny gave to the cashier:

⇒ Change = money given - cost of game

                 = $40 - $30.98

                 = $9.02

Therefore, Jenny received $9.02 in change from the cashier after paying for a game that costs $30.98 with $40.

Answer:

y = 2

Step-by-step explanation:

Given equation:

[tex]2y - 5 = 5y - 11[/tex]

Subtract 5y both sides:

[tex]\implies 2y - 5 = 5y - 11[/tex]

[tex]\implies 2y - 5 - 5y = 5y - 5y - 11[/tex]

[tex]\implies -3y - 5 = -11[/tex]

Add 5 both sides:

[tex]\implies -3y - 5 = -11[/tex]

[tex]\implies -3y - 5 + 5 = -11 + 5[/tex]

[tex]\implies -3y = -6[/tex]

Multiply -1 both sides:

[tex]\implies -3y = -6[/tex]

[tex]\implies \dfrac{-3y}{-1} = \dfrac{-6}{-1}[/tex]

[tex]\implies 3y = 6[/tex]

Divide 3 both sides:

[tex]\implies 3y = 6[/tex]

[tex]\implies \dfrac{3y}{3} = \dfrac{6}{3}[/tex]

The perimeter of the room is 624 inches.

We need 657 tiles to cover the floor.

We need to add 66 extra tiles to account for the overage due to grout and waste.

A rectangle is a 2-D shape with length and width.

The length and width are different.

If the length and width are not different then it is a square.

The area of a rectangle is given as:

Area = Length x width

We have,

Length = 10 ft 9in

Width = 15ft 3 in

a.

Perimeter = 2 (Length + Width)

Length = 10 ft 9 in = (10 x 12) + 9 = 129 in.

Width = 15 ft. 3 in. = (15 x 12) + 3 = 183 in

Perimeter.

= 2(129 + 183)

= 624 in.

b.

Area = Length x Width

Area = 129 in. x 183 in

Area == 23,607 in²

Each tile covers an area of 6 in. x 6 in

Area of tiles = 36 in²

So,

The number of tiles required.

= Area ÷ Tile area

= 23,607 in² ÷ 36 in²

≈ 656.3 tiles.

c.

10% of 657

= 10/100 x 657  

= 0.1 x 657

= 65.7

= 66

Thus,

The perimeter of the room is 624 inches.

We need to add 66 extra tiles to account for the overage due to grout and waste.

Answer:

the rule is multiply input by 25 then add 2, for example 2 x 25 = 50, 50 + 2 = 52

Step-by-step explanation:

this is because you minus 2 from the output to see the pattern from input. For example, 52 - 2 = 50 and to get from 2 to 50 you have to multiply by 25. This can be seen in the other numbers as well. Therefore the answer as a graph will be y = 25x + 2

Answer:

52 divided by 2 equal 26

102 divided by 4 equal 25.5

127 divided by 5 equal 25.4

177 divided by 7 equal 25.28

202 divided by 8 equal 25.25

Step-by-step explanation:

The equation of the ellipse in standard form with vertices along the major axis at (0, 1) and (0, -9) and the foci of the ellipse at (0, -1) and (0, -7) is (y+4)²/16 + x²/25 = 1.

The location of the center of the ellipse is the midpoint of the line segment between the ends of the major axis, that is:

(h, k) = 0.5 · (0, 1) + 0.5 · (0, -9)

(h, k) = (0, -4)

The length of the major semiaxis (b) is 5 and the distance between the center and any of the foci (c) is 3. Then, the length of the minor semiaxis is:

[tex]a = \sqrt{b^{2}-c^{2}}[/tex]     (1)

a = 4

Lastly, we substitute all the variables and conclude that the equation of the ellipse is (y+4)²/16 + x²/25 = 1. [tex]\blacksquare[/tex]

The value of (1/2)x⁴ - (1/4)x² when x = 2 is 7.

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given expression is (1/2)x⁴ - (1/4)x².

We have to calculate the value of the expression when x = 2.

Substitute x = 2 in the expression.

(1/2)x⁴ - (1/4)x² = (1/2) (2)⁴ - (1/4) (2)²

                       = (1/2) × 16 - (1/4) × 4

                       = 16/2 - 4/4

                       = 8 - 1

                       = 7

Hence the value of the expression when x = 2 is 7.

The length of guy wire needed to make an angle of 30° with the ground is 310 feet. The angle between the end of the shadow and the vertical side of the building is 23°

Trigonometric ratio is used to show the relationship between the sides and angles of a right angled triangle.

a) Let l represent the length of the guy wire.

sin(30) = (170 - 15) / l

l = 310 feet

b) Let Ф represent the angle, hence:

tanФ = 100/230

Ф = 23°
