Answer:

- 4 and 3/10

Step-by-step explanation:

- 4.3 = - 4 and 3/10

Answer:

C

2 x 16 = 32

4 x 16 = 64

6 x 16 = 96

8 x 16 = 128

Answer:

1) 5% of 90m= 4.5m

2)25% of 88kg = 22kg

3) 75% of 264= 198

Step-by-step explanation:

1) 90m = 100% (divide by 10)

9 = 10% (divide by 2)

4.5 = 5%

2) 88kg = 100% (keep on dividing by 2)

44kg = 50%

22kg=25%

3) 264 = 100%

132 = 50%

66 = 25% (add)

198=75%

Answer:

240

Step-by-step explanation:

60 = x * 0.25 ----Divide each side by 0.25

60/0.25 = x

240 = x

Answer:

240

Step-by-step explanation:

25% is a fourth of 100%

So if 60 is 25% of something, you would multiply it by 4

60*4=240

Y=2/3x -2

Step-by-step explanation:

Slope 2/3

Y intercept -2

The equation which has a slope of 2/3 and a y-intercept of (0, -2) is; 2x -3y = 6

From line geometry, it follows that the slope of a given straight line is the rate of change in variable y due to a change in variable x.

Hence, the resulting equation is;

Answer:

The answer is B.180°.

Step-by-step explanation:

The figure is rotationally symmetric is after a rotation of a given angle, it still look the same.

In this case of a rectangle, the only way to rotate it so that is look the same, is by rotating it by multiple of 180°, so that the up and down sides flip over, as well as the right and left sides.

Therefore, the only option that applies is B.180°

Answer:

B

Step-by-step explanation:

Answer:

Step-by-step explanation:

A=LW, L=A/W

P=2(L+W), using L=A/W we get

P=2(A/W+W)

P=2(A+W^2)/W

PW=2A+2W^2

2W^2-PW+2A=0, given A=28 and P=22 we have

2W^2-22W+56=0

2(W^2-11W+28)=0

2(W-7)(W-4)=0

So the dimensions are 4ft by 7ft

Answer:15

Step-by-step explanation:

Answer:

The answer is B) 75

Step-by-step explanation:

The angle shown is a 90-degree angle. Therefore if the other angle is 15 degrees, that means that all we have to do is subtract 15 from 90.

90-15= 75 which means the angle known as x is a 75-degree angle.

If the bill of the restaurant comes to $46.27 then the tip of 10% is equal to $4.627.

Percentage is number or ratio that is expressed as a fraction of 100. It is shown by % sign. It shows some quantity over other quantity. The number which shows the percentage is the number in the quantity itself.

We have been given that the bill of the restaurant comes to $46.27 and 10% is the tip. We have to calculate the tip.

Tip=Bill*10/100

=46.27*10/100

=4627*10/100*100

=46270/10000

=$4.627

Hence if the bill of the restaurant is $46.27 then tip will be $4.627.

Step-by-step explanation:

When the sum of two angles is 90°, then the angles are known as complementary angles. In other words, if two angles add up to form a right angle, then these angles are referred to as complementary angles. Here we say that the two angles complement each other. Suppose if one angle is x then the other angle will be 90 o – x

Answer:

A. d = 25; the unit rate is 25 miles per gallon

Step-by-step explanation:

The point (1, d) on the graph represents (x, y), where,

x = gasoline used = 1 gallon

y = distance = d = 25 miles

That is, (1, d) represents when x = 1, y = 25.

Thus, (1, 25) is the unit rate which is 25miles per gallon.
