Solve for g
-6g + 3g + 12 > -18
A.g<2
B.g> 2
C.g<10
D.g> 10​

Answers

Answer 1
Answer:

Answer:

g < 10

Step-by-step explanation:

-6g + 3g + 12 > -18

Combine like terms

-3g +12 > -18

Subtract 12 from each side

-3g+12-12 > -18-12

-3g > -30

Divide each side by -3, remembering to flip the inequality

-3g/-3 < -30/-3

g < 10

When a rectangle is dilated, how do the perimeter and area of the rectangle change?

Answers

A transformation of a figure in which all of the dimensions of the figure are multiplied by the same scale factor is called a dilation.

Effect of Dilation on Perimeter

Whenever a figure is dilated by a scale factor, the perimeter of the figure changes according to the same scale factor.

Effect of Dilation on Area

When a figure is dilated by a scale factor of (a)/(b), the area of the figure is  dilated by a scale factor of (a^(2))/(b^(2))

Example-

Lets imagine a rectangle with length 10 cm and width 8 cm

So area becomes = 10*8 = 80 square cm

Lets suppose the rectangle is reduced by a scale factor of (1)/(2) to produce a new rectangle.

So we will find the square of scale factor = ((1)/(2))^(2)=(1)/(4)

Now to find the area of the new rectangle(dilated one) we will multiply the area of the original rectangle by 1/4

= 80*(1)/(4)=20

Hence, area becomes 20 square cm.

Find six tenths of 80cm

Answers

The best thing to do here is to find 1/10th then multiply.
To do this, divide your number (80) by 10
80/10= 8
As you're looking for sixth tenths, you need to multiply this by 6
8*6= 48
Therefore, six tenths of 80cm is 48cm
Hope this helps :) 
you could change 6 tenths to a percentage, multiply 6 tenths by 100 over 1 and you get 60%, and the you get 60% of 80, put 80 over 100 and multiply it by 60 and you get 48cm

Mr. Hoya brought 5 watermelons from his grocery store. The watermelons weighed 8 1/4 pound, 9 1/4 pound, 8 7/8 pound, 9 5/8 pound, and 10 3/4 pound. At the party 153 people each ate 1/4 pound serving of watermelon. Was the amount of less than or greater than 8 4/8 or 1/2 pounds? Explain how to solve the problem. Then solve it.

Answers

the amount of watermelon consumed was greater than 8 1/2 pounds.

To determine if the amount of watermelon consumed was less than or greater than 8 1/2 pounds, we need to find the total weight of the watermelons Mr. Hoya brought and then subtract the total amount consumed by the 153 people.

1. Find the total weight of the watermelons:

Total weight = 8 1/4 + 9 1/4 + 8 7/8 + 9 5/8 + 10 3/4

2. Convert all the fractions to a common denominator:

Total weight = (33/4) + (37/4) + (35/4) + (39/4) + (43/4)

3. Add the fractions:

Total weight = (33 + 37 + 35 + 39 + 43) / 4

4. Find the sum:

Total weight = 187 / 4

Now, we'll find the total amount consumed by 153 people:

Total amount consumed = 153 * 1/4

Now, we can compare the total amount consumed to 8 1/2 pounds:

8 1/2 = 17/2 = 34/4

Now, let's compare the values:

Total amount consumed = 153 * 1/4 = 153/4 ≈ 38.25

8 1/2 pounds = 34/4 = 8.5

The total amount consumed (38.25) is greater than 8 1/2 pounds (8.5). Therefore, the amount of watermelon consumed was greater than 8 1/2 pounds.

First add all the watermelon weights together (to add the fourths and the eighths multiply the fourths by 2 (1/4x2=2/8) and add the numerators). Then multiply the number of people (153) by how much they each ate (1/4). Then subtract the total amount eaten (38 1/4) from the total weight (46 3/4) and compare that with 8 1/2... The left overs are actually equal to 8 1/2 pounds :)

What is the answer to this?

Answers

The top and bottom are each triangle with base 6 in and height 3 in. So, 6 * 3 / 2 is 9 in^2 for each the top and bottom.

There are 2 rectangles with sides 5 in and 12 in, and 1 rectangle with sides 6 in and 12 in. The areas of the first rectangles are 60 in^2, and the second rectangle is 72 in^2.

Add up the 5 shapes, and you'll have:

9 + 9 + 60 + 60 + 72 = 210 in^2
