Answer:

5×10'2 + 3= 503

Step-by-step explanation:

I'm not sure what the question is asking but if it's asking for the answer of the equation then that's the answer

Define the variables:

y= amt. of $ saved by Darren's friend

x= # of weeks

Darren adds $40 to his savings EVERY WEEK. He also started with $120, so the equation is:

y=40x+120

Answer:

1.156 x 10^-6

Step-by-step explanation:

10^6 = 10x10x10x10x10x10 = 1000000

1.156 ÷ 1000000 = 0.000001156

if you simplify that the answer is 1.156 x 10^-6

Answer:

36 mins

Step-by-step explanation:

7:15 - 6:39 = 36 mins

She finished the race in 36 mins.

Have a good day/night

Answer:

36 minutes

Step-by-step explanation:

You subtract the time she started from the time she finished.

So, it would be 7:15 - 6:39.

It would be easier to find the number that, when added to 6:39, results to 7:00. 

To do so, you subtract 39 from 60.

60 - 39 = 21 minutes

Now, add 21 to 15.

21 + 15 = 36 minutes

Therefore, it took her 36 minutes to complete the race.

Hope this helps!

Part A

To find the area of the unshaded region, subtract the area of the  shaded region   from the sum of the areas of the   rectangle   and   semicircle  

----------------

Explanation:

When it comes to area problems, think of a grid of squares. Let's say we had a 10 by 10 grid of tiny squares (10*10 = 100 total). Now let's say 8 of them are shaded in. There are 100 - 8 = 92 unshaded squares to represent the total area of the unshaded region.

That's effectively what's going on with this problem as well. Sure things get a bit tricky with that curved portion on top, but we can still get an approximation if we use smaller and smaller grid sizes. I recommend using graph paper or graphing software that provides a grid.

========================================================

Part B

----------------

Explanation:

For now, I'm going to ignore the shaded region. I'll come back to it later.

The rectangle is 15 ft by 50 ft. It has an area of length*width = 15*50 = 750 sq ft.

The semicircle up top has an area of [tex]0.5*\pi r^2 = 0.5*\pi*(7.5)^2 \approx 88.3573[/tex]  sq ft approximately. The 7.5 is from dividing the diameter in half to get the radius. As the instructions stated, I used the calculator's version of pi.

The rectangle and semicircle have their areas add to

750+88.3573 = 838.3573

Now we can finally address the shaded region. It is a 3 ft by 9 ft rectangle because "the length is 3 times the width" and the width is 3 ft. This shaded rectangle has area 3*9 = 27 sq ft.

The unshaded region is:

unshaded = total - shaded = 838.3573 - 27 = 811.3573

This rounds to the final answer of 811

Answer:  CD: 8.5

Step-by-step explanation:6^2 = 36

6^2 = 36

36 + 36 = 72

square root 72 = 8.48

so if we round to nearest tenth

CD = 8.5

Answer:

The answer is 1.

Answer:

Step-by-step explanation:

Equations to remember:

Length · Width · Height = Volume

LWH = V

---------------------------------------------------

Length = 5/4

Width = 4/3

Height = 3/5

Your equation will look something like this:

[tex]\frac{5}{4} * \frac{4}{3} * \frac{3}{5} = V[/tex]

or

[tex]\frac{5*4*3}{4*3*5} = V[/tex]

----------------------------------------------------

The simple thing about this problem is that, no matter what order they're in, you're multiplying the same numbers on the top and the bottom. Whatever the top is (5*4*3), the bottom will be (4*3*5). If the top and bottom are equal, that means that you'll have a whole number of 1.

----------------------------------------------------

NOMINATORS

[tex]5 * 4 = 20\\20 * 3 = 60[/tex]

So the top will be 60.

----------------------------------------------------

DENOMINATORS

[tex]4 * 3 = 12\\12 * 5 = 60[/tex]

The bottom will also be 60.

-----------------------------------------------------

[tex]\frac{60}{60} = \frac{1}{1} = 1[/tex]

So your answer will be [tex]1cm^{3}[/tex]!

I hope this helped!

Answer:

5 1/4 - 2 5/7 = ______

5 - 2 = 3

1/4 = 7/28

5/7 = 20/28

7/28 - 20/28 = -13/28

3 -13/28 = 2 15/28

5 1/4 - 2 5/7 = 2 15/28

Answer:

There were 2 1/2 inches of rain in 2 months.

Step-by-step explanation:

1. Reduce 1 6/12 to 1 1/2.

2. Add 1 1/2 and 1 (if it is easier for you to add decimals you can reduce the 1 1/2 to 1.5 by dividing 1 by 2. In that case you would get 2.5 as your final answer). The answer is 2 1/2.

Answer:

The value of z is more than 34.

Answer:

angles 3 and 4 both equal a 90 degree angle or bisect a 90 degree angle.

angle 5 is 44-degrees because it is complementary or vertical to the 44 degree angle.

x=32 because it is on the same line as the 44-degree angle and a line is 180 so 180-44=136 and to get the rest of x you would do the equation backwards so 136 divided by 4 is 34 and 36-2=32

angle a is 136 described above.

angle b, because it is on the same line as the 46 degree angle is 180-46=134

now im pooped :(

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

We can find two clear points. (2.5, -0.5) and (4, 0). The slope is 1/3. So our equation is y=(1/3)x + ?. We can figure out the y-intercept by inputting a point. For example, if we input (4,0), we have 0=(4/3)x + ?. So our y-intercept is -4/3. Our equation is y=(1/3)x-4/3. Rearrange and we have y-(1/3)x=-4/3. We multiply 3 to get rid of fractions. 3y-x=-4. Therefore the equation of the line is  3y-x=-4. Now for the inequality part: The shading is BELOW and the line is bolded (not dotted) so it would be "less than or equal to". So, the inequality of the graph would be 3y-x≤-4.
