Fifteen points! HELP!

Answer:

The answer is no because for 1 hour he gets 20 dollars and for 2 hours he gets 30$ (which is less for working 2 hours). So, if you multiply 2 hours with 20 dollars, you should get 40, not 30. So therefore, it is not proportional. And same for 3 hours: multiply 3 with 20 to get 60, not 50.

Answer:

draw a line that makes a triangle and rectangle.

hypotenuse= 30

3k-4k-5k triangle

18-24-30

so the short part of triangle is 18 cm

10+10+18+24+30 equals 92

sorry for language I am not familiar with English

the perimeter of this shape is

24+10+10+30+\(\sqrt{30^{2} -24^{2} }\) = 92 cm

Answer:

maybe 38cm^2

I'm not confident about it though

Answer:

A 9%

Step-by-step explanation:

There are 100 boxes and only 9 are shaded so a fraction of that would be 9/100 so if you convert that to a percentage it would be 9% of the boxes

so therefor 9% is you answer

Answer:

B, C, F ................................keep it simple

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

2x − (3 − x) > x + 1

Distribute the minus sign

2x-3+x > x+1

Combine like terms

3x-3 >x+1

Subtract x from each side

3x-3-x>x+1-x

2x-3 >1

Add 3 to each side

2x-3+3>1+3

2x>4

Divide by 2

2x/2 >4/2

x>2

Open circle at 2 , line going to the right

Answer:7

Step-by-step explanation:

Answer: 10/3 (ten-thirds)

Step-by-step explanation:

Dividing 2/3 profit of selling concert tickets by 1/5 profit from selling band merchandise.

(2/3) / (1/5) = 10/3 = 3 1/3

Hence band members make 3 1/3 or 10/3 times more profit from ticket sales than from band merchandise sales.

This can be elaborated in such a way also.

Let suppose the total profit is $30.

then the profit from the ticket sale = 2/3 of 30 = $20

and the profit from the band merchandise sales = 1/5 of 30 = $6

Now dividing 20 by 6, which gives 10/3. The same answer that was calculated above.

Answer:

1. 2/3

2. 3 to 2

3. 3:5

Step-by-step explanation:

1.

10/15 divide by 5

10/15 = 2/3

2.

21 to 14 divide by 7

21 to 14 = 3 to 2

3.

15:25 divide by 5

15:25 = 3:5

Answer:

110/3 or 36 2/3

Step-by-step explanation:

4 3/10-2 7/15=11/6

11/6•20=110/3

Answer:

110/3 or 36 2/3

Step-by-step explanation:

Evaluate the parenthesis first which is 11/6. Multiply that by 20 to get 110/3 or 36 2/3

Answer:

x=5

Step-by-step explanation:

step1: subtraction 7 from both sides (from 7 itself and 22)

step 2: divide both sides by 3

3x +7 =22

     -7 =-7

     3x=15

3x/3 = 25/3

   x=5

Answer: The circumference of the cylinder's base is 6 units.

Radius = 1/2(6/pi)

Volume = r2pi*h

h = (27/2) / r2pi

sin(∠BAD) = h / 6

Answer:

B, the difference of x and 2 all divided by 3 plus x squared

Step-by-step explanation:

Break it down...

(x-2) = x minus 2 or the difference of x and 2

/3 = divided by 3

+ = plus

x^2 = x squared

Step-by-step explanation:

Answer:

Answer is in the attached photo.

Step-by-step explanation:

The solution is in the attached photo, do take note to solve this question, angles properties must be used.

Answer:

x=48°

Step-by-step explanation:

We can see the line at the top. 52°+y+59°=180° because these angles are supplementary angles. We can solve this problem:

52°+y+59°=180°

y=180-52-59

y=180-111

y=80-11

y=69°

because the angles in a triangle add up to 180°, y+63°+x=180°, or

69°+63°+x=180°

We can solve it from here:

69+63+x=180

120+12+x=180

132+x=180

x=180-132

x=80-32

x=48°

Answer:

40 in.²

Step-by-step explanation:

First, you have to find the area of the triangle, which you then multiply by 4 (because there are 4 triangles):

A=1/2(bh)

A=1/2(3x4)

A=1/2(12)

A=6

6x4=24 in.²

Next, you have to find the area of the square:

A=bh

A=4x4

A=16

Now, add 24 and 16 together to get your answer of 40 in.².

Answer:

1/3

Step-by-step explanation:

just convert it?

3/10

Step-by-step explanation:

60% is the same as 60/100

90% is the same as 90/100

90-60=30

30/100

30/100 is divided by 10 on each side to simplify it to 3/10

Answer:he used the hatchet by making a fire

Step-by-step explanation:

Answer: The total percentage decrease in the investor's stock account is 34%

Step-by-step explanation:

The investor's stock in Company A= $3800

The investor's stock in Company B= $3400

Percentage decline in stock of company A= 22%

Decline in value of stock of company A= 3800× 22/100

= 38×22

= $836

Percentage decline in stock of company B= 3400×12/100

= 34×12

=$408

Total decline in wealth of investor= 836+ 408

= $1244

Total percentage decline in wealth= 1244×100/7200

= 124400/7200

= 17.27%

The percentage decrease in investor's stock is 17.27%
