An art teacher is buying clay by the pound. The teacher buys pounds of clay for $7.50. How much will pounds of clay cost? A. $8.25 B. $15.75 C. $9.09 D. $9.90

The amount saved is $0.80 or 80 cents.

Since Soil sells for 8 1/4 cents per pound, the coat for 100 pound sack will be:

= 8 1/4cents × 100

= 8.25 cents × 100

= 825 cents

Since 100 cents = $1

825 cents = 825/100

825 cents = $8.25

Since the 100 pound sack was bought for $7.45, the amount saved will be:

= $8.25 - $7.45

= $0.80

Answer:

  99°

Step-by-step explanation:

If we assume that angles 5 and 7 are vertical angles, they are congruent:

  10x -9 = 9x

  x = 9 . . . . . . . add 9-9x

Then angles 5 and 7 are ...

  (10·9 -9)° = 9·9° = 81°

Angle 6 will be the supplement to this.

  angle 6 = 180° -81°

  angle 6 = 99°

Answer:

7/8

Step-by-step explanation:

we need to same denominator. 3/4 is equal to 6/8

1/8+6/8 is 7/8.

Answer:

7/8 or 0.875

Step-by-step explanation:

1/8 + 3/4=?  

The Least Common Multiple (LCM) of 8 and 4 is 8. Multiply the numerator and denominator of each fraction by whatever value will result in the denominator of each fraction being equal to the LCM:

1/8 + 3/4= 1/8 + 3 x 2 = 1/8 + 6/8

                         4 x 2

Now that the fractions have like denominators, add the numerators:

1/8  + 6/8 = 1+6 = 7/8

                    8

Answer:

1.3 m²

Step-by-step explanation:

The shape is a trapezoid.

Area of a trapezoid = ½(a + b)*h

Where, a = 0.8 m

b = 1.8 m

h = height of the trapezoid which is not given.

Therefore, find h using trigonometric function with 45° as reference angle:

Hypotenuse = 1.4 m

Opposite = h

Apply SOH, which is:

Sin 45 = Opp/Hyp

Sin 45 = h/1.4

1.4*Sin 45 = h

0.989949493 = h

h ≈ 1.0 m

✔️Area of Trapezoid = ½(0.8 + 1.8)*1 = 1.3 m²

Answer: Melanie has the most money at the end of the week.

Step-by-step explanation:

Melanie gets the 1 weekly allowance. But it could also depend on how much her weekly allowance is. Your bus rides aren't a lot, so riding the bus 7 times doesn't take much money. She also gets paid for 2 hours, so she could be working somewhere with more money being paid by the hour. While on the other hand, Dana could be working a minimum wage job and wasting more money, because she also pays for food. She could be on her own and have to spend more money for her needs and the things she would need. (And because it says Melanie gets 1 weekly allowance that means she still lives with her parents so they pay for her benefits and things she needs.)

Answer:

D. m= 60, n= 24

Step-by-step explanation:

The angle marked with blue, will also be 2m° (Vertically opposite angles)

So, 2m = (4m- 120)°

2m = 120°

m = 60°

Now, (4m-120)° = 5n° (Vertically opposite angles)

[4(60)- 120]° = 5n°

240- 120 = 5n°

120/5° = n

n= 24°

Answer:

it decreased by 5.55% change of 6%

The relative change is -6% Rounding to the nearest percent.

The average can be calculated by dividing the sum of observations by the number of observations.

Average = Sum of observations/the number of observations

The relative change can be calculated by dividing the absolute change (the subtraction of the values) by the initial value.

The absolute change is the final value minus the initial value;

Absolute change = 51000 - 54000 = -3000

Now, calculating the relative change;

Relative = -3000/54000

Relative = - 0.0555

Since the relative change is negative, this change indicates a decrease.

Therefore, the relative change is -6% Rounding to the nearest percent.
