a) The length of a rectangle is 3 m longer than its width and the area of the rectangle is 108 m². Find its length.

Answers

Draw a rectangle. If the length is 3 inches longer than its width, we can write the width as "w" and the length as the width + 3
Area is (width)(Length) = (width)(width+3)

W
----------
| |
| |
| | L = w+3
| |
| |
-----------

A = (w+3)(w)
A = w2 + 3w = 108.
(Problem states that area is 108 sq in)

Need to solve this quadratic equation

w2 + 3y - 108 = 0

Factor:
(w - 9) (w + 12) = 0

So
w - 9 = 0. or. w + 12 = 0

Solve these and get
w = 9. or. w = -12

Only one that makes sense in real life is the poitive one.

So the dimensions are

Width = 9 inches
Length = 12 inches

Answer:

the lowest common factor is 5

Step-by-step explanation

5 can go into both 60 and 10, and thats the lowest that can go into both numbers because 5 times 2 is equal to 10 and 5 times 12 is equal to 60. hope this helps :)

If R is the midpoint of TS, TR = 5x - 12, and RS = 3x + 8, find TS.

Answers

Answer:

5x -12 = 3x +8 (set the two = each other because they are the same length)

2x- 12= 8 (subtract 3x from both sides)

2x = 20 (add 12 to both sides)

x=10 (what x= for both expressions)

5(10) -12 (plug it into the first one to see what the length is and to see they're =

50 - 12 ( I already multiplied, now subtract)

38 (what the length of TR is)

3(10) +8 (plug it in again but into the other expression)

30+8 (multiply and add)

38 (the two have the same answer, so the x-value is correct.)

38+38= 76 (add the lengths of RS and TR and you get the length of TS)

Step-by-step explanation:

I hope this helps :)

Applying the segment addition theorem, the value of TS is: 76

Given:

TR = 5x - 12

RS = 3x + 8

If T is the midpoint of TS, therefore we would have the following equation:

TR = RS

Plug in the expressions

5x - 12 = 3x + 8

Add like terms together

5x - 3x = 12 + 8

2x = 20

Divide both sides by 2

x = 10

TS = TR + RS (segment addition theorem)

Substitute

TS = 5x - 12 + 3x + 8

Plug in the value of x

TS = 5(10) - 12 + 3(10) + 8

TS = 50 - 12 + 30 + 8

TS = 76

In a recent survey 5/8 of the Siamese cat said that they didn't mind having a lap up water from a bowl but another 3/16 admitted they would have preferred to use a straw instead of 39 of the Siamese cats gave one of these two answers how many were surveyed in total make sure your answer is fully reduced

Answers

Answer:

48 Siamese cats were surveyed

Step-by-step explanation:

Let x represent the total number of surveyed Siamese cats.

Since 5/8 of the Siamese cat said that they didn't mind having a lap up water from a bowl , hence:

Number of cats who lapped = (5/8)x

Also, 3/16 admitted they would have preferred to use a straw:

Number of cats who used straw = (3/16)x

Taking into consideration that 39 of the Siamese cats gave one of those two answers:

(5/8)x + (3/16)x = 39

(13 / 16)x = 39

x = 39 * 16 / 13

x = 48

48 Siamese cats were surveyed

d = vt

where:

v = speed

d = distance

t = time

Based on the formula, each quantity is directionally proportional to each other. Since we don't have enough numbers to work with, we will utilize our concept skills.

If the car travels half the speed, then the car is slowing down and covers a short distance in a certain amount of time than it did originally. So we divide the default distance by 2.

180 / 2 = 90

The new distance so far is 90 miles.

But now it takes the car 3 times as long to get to its destination. The longer it takes, the more distance you will cover. Multiply the current distance by 3.

90 * 3 = 270

The car travels 270 miles.

Answer:

C.) y = 5/4x - 4

Step-by-step explanation:

Points: (0,-4) and (4,1)

m = y2 - y1/x2 - x1

m = 1 - (-4)/4 - 0

m = 1 + 4/4

m = 5/4

Point: (4,1) (you may choose any points, but I will choose these since they are the easiest to work with)

y - y1 = m(x - x1)

y - 1 = 5/4(x - 4)

y - 1 = 5/4x - 5

y = 5/4x - 5 + 1

y = 5/4x - 4

This formula is used to calculate the weekly pay of a letting agent. Weekly pay = basic pay + number of houses rented x bonus The basic pay is £400 and a bonus of £75 is paid for each house rented. Mrs Lewis rents out 5 houses in one week. Calculate her pay.

Answers

Answer:

£775

Step-by-step explanation:

From the question, it was given that:

Weekly pay = basic pay + number of houses rented x bonus

This expression can be used to determine the amount of money being paid to the agent every week.

When basic pay = £400, bonus = £75, and the number of house rented = 5.

Then,

Weekly pay = 400 + 5(75)

= 400 + 375

= 775

Weekly pay = £775

The amount of money paid to Mrs Lewis every week is £775.

Find the slope of 6x – 3y = 5

Answers

Answer:

slope is 2

Step-by-step explanation:

simplify this equation so that you can get to "y ="

your equation is: 6x - 3y = 5

start by subtracting 6x from both sides: -3y = -6x - 5

then divide both sides by -3 to isolate y: y = 2x - 5/3

so now we can clearly see that the slope is 2, since that is what is right next to x
