The following questions are related to problems on simple fraction and arithmetic. Hence, the solutions to the questions are as follows :

1.)

Time on mathematics =<em> 1 hour</em>

Time on science homework = <em>7/8</em><em> hours</em>

Total time spent = (1 + 7/8) = 1 \frac{7}{8}

2.)

Total number of students = <em>60</em>

Fraction of girls = <em>3/4</em>

Fraction of boys = 1 - 3/4 = 1/4

Number of boys = 1/4 × 60 = 15 boys

3.)

Initial temperature = <em>- 2°C</em>

Final temperature = <em>8°C</em>

Change in temperature = Final temperature - Initial temperature

Change in temperature = (8 - (-2)) = 8 + 2 = 10°C

4.)

Elevation of everest = <em>20028 feets </em>

Elevation of dead sea =<em> - 485 feets</em>

Difference in elevation = (20028 - (-485)) = 20513 feets

5.)

Question is missing key values.

Order the following integers from least to greatest.-41, -53, -73, -78 A. -78, -53, -73, -41 B. -78, -73, -41, -53 C. -73, -78,
irakobra [83]

The value of negative integers decreases the further we get from the 0 point on the number line.

Therefore, if we arrange the numbers in ascending order ignoring the negative sign, the numbers will be in descending order when the negative sign is included.

By the definition above, we can say that the smallest number of the lot is -78 and the largest one is -41.

The numbers can be ordered from least to greatest as shown below:

-78,-73,-53,-41

OPTION D is the correct answer.

➷ As there would be 2 circles, you'd need to find the area of a circle and then multiply it by 2

To start with, we can use this:

2 (\pir^2)

^^ This represents the surface area of the two circles

A cylinder also has a rectangle which is rolled to form the shape

As we know, the formula of a rectangles area is length x width

The width of the rectangle would be equal to the circumference of a circle

circumference of circle = \pi d

The length of the rectangle would be the height of the cylinder

We can use this:

(\pi d * h) + 2(\pi r^2)

This would calculate the surface area as it would find the area of the rectangle plus the area of the two circles.

<h3><u>✽</u></h3>

➶ Hope This Helps You!

➶ Good Luck (:

➶ Have A Great Day ^-^

Find the measure of A (Please help asap and show work)
Alex17521 [72]

Answer:

Step-by-step explanation:

x + 32 + 2 vertically opposite degrees = 180      Beginning condition

x + 32 + x + 126 + 36 = 180                                   Combine like terms

2x + 194 = 180                                                       Subtract 162 from both sides

2x = -14

x = -7

========

So the three angles are

36

-7 + 32 = 25

-7 + 126 = 119

Total = 180

That negative can throw you for a loop.
