Mary has two sisters. Her younger sister is 5 years younger Her older
sister is twice her age. Their ages add up to 47. How dd is Mary and each
of her sisters?

Answers

Answer 1
Older sister is 26, Mary is 13, and younger sister is 8.
Explanation:
26 + 13 + 8 = 47
If the older sister is 26, then Mary is half that, meaning: 26/2 = 13
Mary is 13, and her younger sister is 5 years younger so: 13-5 = 8
Her younger sister is 8.
To double check, add up the ages and see if you get 47.
26 (older sister) + 13 (Mary) + 8 (younger sister) = 47

The composite figure is made up of three simpler shapes. What is the area of the figure?
Please explain how you got your answer, please.

Answers

Answer:

C) 55 cm^2

Step-by-step explanation:

(12x3)+(8x2)+(1/2)(3)(2) = 55

The area of composite figure is 55 square cm .

What is area?

The space occupied by a flat shape or the surface of an object is called area.

Formula for the area of triangle

[tex]A = \frac{1}{2}bh[/tex]

Where,

A is the area of triangle

b is the base of the triangle

h is the height of the triangle

Formula for the area of parallelogram

A = b × h

Where,

A is the area of parallelogram

b is the base of parallelogram

h is the height of the parallelogram

Formula for the area of rectangle

A = length × breadth

According to the given figure

Composite figure is made up of triangle, rectangle and parallelogram

Also,

Height of triangle = 3cm

Base of the triangle = 2cm

length of the rectangle = 8cm

breadth of the rectangle = 2cm

Height of the parallelogram = 3cm

Base of the parallelogram = 12cm

Therefore,

Area of triangle = 1/2 × 3 ×2 = 3 square cm

Area of rectangle = 2 × 8 = 16 square cm

Area of parallelogram = 12 × 3 = 36 square cm

Therefore,

Area of the composite figure = area of triangle + area of parallelogram + area of rectangle

Area of composite figure = 36 + 16 + 13 = 55 square cm.

Hence, the area of composite figure is 55 square cm .

Mr. Ryan had 8 meters of cable. He used 300 centimeters to hook up the television in his living room. Then he used 400 centimeters to hook up the television in his office. How many meters of cable did Mr. Ryan have left?

Answers

Answer:

1 meter left

Step-by-step explanation:

100 cm makes up a meter so 300 + 400 is 700 which is 7 meters so he has 1 meter left

Answer:

Mr. Ryan has 1 meter or 100 centimeters ethier (answer is correct)  

Step-by-step explanation:

How many meters of cable did Mr. Ryan have left?

Let's start here with that for every meter(m) there is 100 centimeters(cm) so in other words 1 meter = 100 centimeters

300 cm=3 m           400 cm=4 m

3m+4m=7m             300cm+400cm=700cm

Step-by-step explanation:

Starting with the fact that angles 1 and a are a linear pair and that angles b and 2 are also a linear pair, use a two column proof to prove that consecutive interior angles a and bare supplementary ( 5 points)

Answers

Answer:

See proof below

Step-by-step explanation:

Two angles that are linear pair sums up to 180°

If angles 1 and a are a linear pair and that angles b and 2 are also a linear pair, then;

1+a = 180....1

2+b= 180....2

Taking the sum of both equations

1+2+a+b = 360°... 3

Note that the sum of the adjacent angles will also be 180° since they also lie on the same straight line, hence;

1+2 = 180°...4.

Substitute 4 into 3

From 3;

1+2+a+b = 360°

(1+2)+(a+b) = 360°

180+(a+b) = 360

a+b = 360-180

a+b = 180

Since the sum of a and b is 180°, this shows that angles are supplementary since the sum of 2 supplementary angles is also 180°

Hence this shows that the consecutive interior angles a and bare supplementary.

Answer:

180-35=145 Degrees

Step-by-step explanation:

TBH I may not have a complete understanding; but what I do know is a straight line (or angel if you so chose) is equal to 180 degrees (NOTE: supplementary- angels are when 2 angels that are added up to 180 degrees) and on my part of the question is: "Starting with the fact that angles 1 and a are a linear pair and that angles b and 2 are also a linear pair, use a two column proof that consecutive interior angles a and b are supplementary".

Now in my whole complete course its asking a bout a ski slope and it gives me the 35 degree angle and we need to figure out the missing angle, we have the same picture as listed above.... knowing that straight lines are 180 degrees I subtracted 180-35 and I got 145 degrees now either i'm right or i'm missing som I did in a few years back but most of my information is basically backed up by some understanding I do know

Answers

First, to find an average, we need to add all the numbers together and divide them by how many numbers there are.
36+38+34+92+36+34+40+44+32+34 = 420
420/10 = 42

Average = 42

The pairs of numbers below represent the price of different
quantities of books at 4 stores.
Which pair of numbers represents a proportional relationship?
o 4 books for $24,8 books for $40
o 5 books for $25, 6 books for $36
o 2 books for $14, 5 books for $35
o 3 books for $15, 7 books for $28

Answers

Answer:

Option C: 2 books for $14, 5 books for $35

Step-by-step explanation:

A proportional relationship between two quantities would always have a constant of proportionality. Thus,

Constant of proportionality, k = y/x

In this case,

x = quantity of books

y = price

Let's see which pair will have a constant of proportionality:

Option A: 4 books for $24,8 books for $40

24/4 = 6;

40/8 = 5.

No constant of proportionality.

Option B: 5 books for $25, 6 books for $36

25/5 = 5

36/6 = 6

No constant of proportionality.

Option C: 2 books for $14, 5 books for $35

14/2 = 7

35/5 = 7

Constant of proportionality, k = 7.

This pair represents a proportional relationship.

Option D: 3 books for $15, 7 books for $28

15/3 = 5

28/7 = 4

No constant of proportionality.
