Answer:

6 days

Step-by-step explanation:

The equation for first warehouse would be:

210 + 90x

The equation for 2nd warehouse would be:

180 + 120x

Where x is he number of days.

<em><u>In how many days will the first warehouse have 1.2 times less potatoes than the second warehouse?</u></em>

This means the first warehouse expression TIMES 1.2 would give us 2nd warehouse expression. Equating and solve:

180+120x=1.2(210+90x)\\180+120x=252+108x\\12x=72\\x=\frac{72}{12}\\x=6

So it would require 6 days

Johnny sold crafts at a show. His prices included .07 sales tax. Johnny grossed $1236.00. What was johnny's taxable amount?
Vadim26 [7]

The taxable amount was $80.86

Step-by-step explanation:

Given,

Sales tax = .07

Total grossed = $1236.00

Let,

x be the price before sales tax, therefore,

Amount of sales tax = 0.07x

Price before sales tax + Sales tax = Total amount grossed

x+0.07x = 1236

1.07x=1236

Dividing both sides by 1.07

\frac{1.07x}{1.07}=\frac{1236}{1.07}\\x=1155.14

Taxable amount = Total amount grossed - Price before tax

Taxable amount = 1236 - 1155.14 = $80.86

The taxable amount was $80.86

A triangular pyramid with a height of 9 inches has a volume of 63 cubic inches. If the height of the triangular base is 6 inches
Bond [772]

Option D: 21 in is the base length of the triangular base.

Explanation:

Given that a triangular pyramid with a height of 9 inches has a volume of 63 cubic inches.

The height of the triangular base is 6 inches.

We need to determine the base length of the triangular pyramid.

The base length of the triangular pyramid can be determined using the formula,

Volume =\frac{1}{3} \times Bh

Substituting Volume=63 and Height=9 in the above formula, we get,

63 =\frac{1}{3} \times B(9)

Simplifying the terms, we get,

63 =3B

Dividing both sides by 3, we have,

21=B

Thus, the base length of the triangular pyramid is 21 in

Hence, Option D is the correct answer.
