Answer:

$720

Step-by-step explanation:

$1,200 divided by 2 (600) equals how many vanilla cupcakes there were.

40 people times 24 cupcakes each person (960) equals how many total cupcakes there were.

The total amount of cupcakes minus the amount of vanilla cupcakes equals the amount of chocolate cupcakes (960-600=360).

360 chocolate cupcakes times the amount each cupcake was sold for equals the amount of money raised from the chocolate cupcakes (360x2=720).

what is the slope of a 5-foot high platform that begins at ground level 10 feet from the base of the platform?​
Sladkaya [172]

Answer:

11.2 feet

Step-by-step explanation:

Given: Height of platform (Opposite)= 5 foot

            Distance of slope from the base of platform (adjacent)= 10 feet

Picture drawn to show the measurement.

Lets find the length of slope.

Using the Pythagorean theoram.

hypotenous^{2} = opposite^{2} + adjacent^{2}

Subtituting the value in the formula.

hypotenous^{2} = 5^{2} + 10^{2}

⇒ hypotenous^{2} = 25 + 100

⇒ hypotenous^{2} = 125

Putting square root on both side

We know, √a²= a

⇒ hypotenous = \sqrt{125}

∴ hypotenous= 11.18 \approx 11.2 \ feet

Hence, the slope is 11.2 feet

Chance has hired a construction crew to renovate his kitchen. They charge $3.55 per square foot for materials and $121.26 per da
Fantom [35]

The renovation took 14 days ⇒ answer A

Step-by-step explanation:

Chance has hired a construction crew to renovate his kitchen

  • They charge $3.55 per square foot for materials
  • They charge $121.26 per day of labor
  • Chance spent $2,450.24 on the renovation
  • The number of square feet is 198 more than the number of days it took for the renovation

We need to find for how long the renovation took

Assume that the renovation took x days

∵ The renovation took x days

∵ The number of square feet is 198 more than the number of days

∴ The number of square feet = x + 198

∵ They charge $3.55 per square foot

∵ They charge $121.26 per day of labor

∴ The cost of renovation = 3.55(x + 198) + 121.26(x)

- Simplify the expression

∴ The cost of renovation = 3.55 x + 702.9 + 121.26 x

- Add like terms

∴ The cost of renovation = 124.81 x + 702.9

∵ Chance spent $2,450.24 on the renovation

- Equate the cost of renovation by the money that Chance spent

 on the renovation

∴ 124.81 x + 702.9 = 2,450.24

- Subtract 702.9 from both sides

∴ 124.81 x = 1,747.34

- Divide both sides by 124.81

∴ x = 14

The renovation took 14 days
