Answer 1: at 8:15, the hour hand is at an angle of 247.5 degrees. The hour hand is at an angle of 105 degrees, whereas the minute hand is at an angle of 180 degrees

Answer 2: What is the measure, in degrees, of the acute angle formed by the hands of a 12-hour clock that reads exactly 3:10? Explanation: The entire clock measures 360°. As the clock is divided into 12 sections, the distance between each number is equivalent to 30° (360/12)

Here is the question | | | | v

Answer:

16.5 square feet

Step-by-step explanation:

The logo consists of

rectangle with sides of 3 ft and 1.5 ft;
trapezoid with bases 3 ft, 4 ft and height of 3 ft;
triangle with base of 1.5 ft and height of 2 ft.

The area of rectangle:

$A_{rectangle}=1.5\ ft\times 3\ ft=4.5\ ft^2$

The area of trapezoid:

$A_{trapezoid}=\dfrac{3\ ft+4\ ft}{2}\times 3 \ ft=3.5\ ft\times 3 \ ft=10.5 \ ft^2$

The area of triangle:

$A_{triangle}=\dfrac{1}{2}\times 1.5\ ft\times 2 \ ft=1.5\ ft^2$

Hence, the area of logo:

$A=A_{rectangle}+A_{trapezoid}+A_{triangle}=4.5\ ft^2+10.5\ ft^2+1.5\ ft^2=16.5\ ft^2$

Help needed. Will mark brainliest. Please help:c

Alja [10]

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Cost of owning and operating a printer :

Purchase Cost = $100

Printing per per page = $0.05

Thus, owning and operating cost :

Purchase cost + (Printing per page * number of pages)

Number of pages = p

100 + 0.05p

Service cost :

Amount per page = 0.25

Total revenue = cost per page * number of pages

Total revenue from service =. 0.25p

The equation :

100 + 0.05p = 0.25p ; is the owning and operating cost = total revenue

It gives the equation to calculate the number of pages at which total revenue equals owning and operating cost.

100 + 0.05p = 0.25p

100 =0.25p - 0.05p

100 = 0.20p

p = 100/0.2

p = 500

When number of pages equals 500; the owning and operating cost is equal to the revenue made.

In one day's work at the nursery, Dale and Mary together potted 74 plants. If Dale potted 48, how many did Mary pot?

dybincka [34]

You would subtract the number of plants dale potted from the total amount. 74-48=26

the pre-image of a triangle are A(-3,1), B(-1,0) and c(-1,4) if c maps to C' (-3,0) what's the rule of the translation and the c

Hatshy [7]

To get from C(-1, 4) to C'(-3,0), we must subtract the x value by -2. This gets us -3 (-1-2=-3). To get from 4 to 0, we must subtract the y-values by 4. This gets us a translation of 2 left and 4 down or T₋₂,₋₄
