Yes! the dots are moving in a certain direction and are all remotely by each other. it would not be linear if they were all far apart and not in a trend.

Find the area of a sector with a central angle of 32° and a radius of 8.5 millimeters. Round to the nearest tenth.

Mrrafil [7]

360 degrees in a circle
32/360 of total area is sector area

area=pir^2
r=8.5
area=pi8.5^2
area=226.980022 mm^2
multiply it by 32/360
sector=20.17600195555556

round
sector=20.2

It takes a man 3 hours to wash and wax the family car. If his teenage son helps him, it only takes one hour. How long will it ta

Aleonysh [2.5K]

Answer:the son working alone will take 1¹/₂ hours

Step-by-step explanation:

Step 1

let x represent the hours that the son needs to wash and wax the car alone thus his rate is 1/x cars per hour

While

the rate of the father is 1/3 cars per hour , working together rate is 1/1 cars per hour.

Step 2

Writing it mathematically, becomes

1/x + 1/3 = 1/1

Dividing through by 3x so all denominations can be rqual to 1 , we have

3 + x = 3x

3= 3x-x

3= 2x

x= 3/2

Therefore the son working alone will take 1¹/₂ hours

Y=3(x-2)+1 how can i graph this into slope intercept form

liraira [26]

Answer: y=3x--5

Step-by-step explanation: First simplify by distribution and lie terms to get:

y=3x-5

3 is your slope which means every time your y goes up three your x goes across one.

-5 is your y-intercept which means (0,-5) goes through your line

A shipment of 205 Otter Box covers for i-phones has just arrived. The total invoice (excluding tax, shipping, etc.) is $ 4,829.7

Harrizon [31]

45 otter box defender series covers are in the shipment

<h3><u><em>Solution:</em></u></h3>

Let the number of Otter Box Defender cover be x

Let the number of Otter Box Case cover be y

Cost of 1 Otter Box Defender cover = $ 39.95

Cost of 1 Otter Box Case cover = $ 18.95

<em><u>Given that shipment of 205 Otter Box covers for i-phones has just arrived</u></em>

Therefore,

number of Otter Box Defender cover + number of Otter Box Case cover = 205

x + y = 205 ---------- eqn 1

<em><u>Given that total invoice is $ 4829.75</u></em>

Therefore,

number of Otter Box Defender cover x Cost of 1 Otter Box Defender cover + number of Otter Box Case cover x Cost of 1 Otter Box Case cover = 4829.75

$x \times 39.95 + y \times 18.95 = 4829.75$

39.95x + 18.95y = 4829.75 ------ eqn 2

<em><u>Let us solve eqn 1 and eqn 2</u></em>

From eqn 1,

x = 205 - y ----- eqn 3

<em><u>Substitute eqn 3 in eqn 2</u></em>

39.95(205 - y) + 18.95y = 4829.75

8189.75 - 39.95y + 18.95y = 4829.75

-21y = 4829.75 - 8189.75

-21y = -3360

From eqn 3,

x = 205 - y

x = 205 - 160

Thus 45 otter box defender series covers are in the shipment
