ludmilkaskok [199]

Answer:

The given equation in slope intercept form is

226.50 = 7.5 (25) + 39

Step-by-step explanation:

The SLOPE INTERCEPT form of a equation is y = m x + c

The per hour cost for rental of boat = $25 per hour

Let us assume the one time cleaning charge = $ k

The boat is booked from 11 am : 6 : 30 pm

So, the number of hours boat was used = 7 . 5 hours

Hence, the cost for engaging boat for 7.5 hours

= 7.5 (cost per hour ) = 7.5( $25) = $187 . 5

Total amount paid by the family = $226. 50 = Fixed cleaning charge + rate for 7.5 hours

⇒The cleaning fee paid by the family = $226. 50 - $187 . 5 = $39

According to question:

Total amount paid = Number of hour x (cost per hour ) + Cleaning fee

Hence, the given equation in slope intercept form is

226.50 = 7.5 ($25) + $39

The pillars in front of Mr. Jefferson's home are shaped like cylinders. The pillars have a height of 24 ft and a radius of 8 in.

GREYUIT [131]

Answer:

Option A. about 100.5ft²

Explanation:

Since the bases must not be painted, their areas are not included in the calculation.

The surface to paint, of each pillar, is equal to the lateral area of a cylinder with he dimensions given.

The formula for the laeral area of a cylinder is:

$Lateral\text{ }area=2\pi \times radius \times height$

Substitute including the conversion factor to convert inches to feet:

$Lateral\text{ }area=2\pi \times 8in\times 1ft/12in \times 24ft=100.5ft^2$

What is the value of the expression below when x=4x=4? 7x^2 +8x-7 7x 2 +8x−7

Vinil7 [7]

Answer: 137

Step-by-step explanation:

The given expression: $7x^2 +8x-7$

We need to find the value of the expression when x=4.

So we just use the substitution property and substitute the value of x= 4 in the given expression , we get

$7(4)^2+8(4)-7\\\\= 7(16)+32-7\\\\= 112+25\\\\=137$

Hence, the value of the expression at x=4 is 137.

Henri has $24,000 invested in stocks and bonds. The amount in stocks is $6,000 more than three times the amount in bonds. How mu

kotykmax [81]

Answer:

The amount of investment in bonds is US$ 4,500 and the amount of investment in stocks is US$ 19,500

Step-by-step explanation:

Total investment in stocks and bonds = US$ 24,000

Amount of investment in bonds = x

Amount of investment in stocks = 3x + 6,000 (amount in stocks is $6,000 more than three times the amount in bonds)

For finding the value of x (amount of investment in bonds), we use this equation:

x + 3x + 6,000 = 24,000

x + 3x = 24,000 - 6,000

4x = 18,000

x = 4,500 (dividing by 4)

The amount of investment in bonds is US$ 4,500

Now let's find the amount of investment in stocks:

3x + 6,000 = 3 (4,500) + 6,000 = 13,500 + 6,000 = 19,500

The amount of investment in stocks is US$ 19,500
