Answer:

Time taken by Franklin to shovel alone is 65.5 minutes.

Step-by-step explanation:

Let the time taken by Franklin to shovel alone = x minutes.

Since, the time taken by Angela to shovel = 180 minutes and the time taken by both = 48 minutes.

Then, we have,

Amount of shoveling done in 1 minute by Angela = \frac{1}{180}

Amount of shoveling done in 1 minute by both = \frac{1}{48}

Amount of shoveling done in 1 minute by Franklin= \frac{1}{x}

So, we have,

\frac{1}{180}+\frac{1}{x}=\frac{1}{48}

i.e. \frac{x+180}{180x}=\frac{1}{48}

i.e. 48(x+180)=180x

i.e. 48x+8640=180x

i.e. 132x=8640

i.e. x= 65.5 minutes

Thus, the time taken by Franklin to shovel alone is 65.5 minutes.

Using the pythagorean theorem, calculate the length of the missing sides (c1, c2, c3)​
katrin [286]

Answer:

the Pythagorean theorem states:  a^2 + b^2 = c^2  

1) in this case a=18 and b1=25

18^2 + 25^2 = c1^2  

324 + 625 = c1^2

949 = c1^2

√949 = c1

cca. 30.8 = c1

2) in this case a=18 and b' = b2 - b1 = 40 - 25 = 15

in the picture im attaching i highlighted the triangles we are working with, and there you can clearly see that b' (the horizontal line at the bottom of the red tr.) is the difference between the lines b2 and b1

now you can use the same technique as in the first case, and the final answer will be cca. 23.4 = c2

3) in this case a=18 and b'' = b4 - b3 = 75 - 55 = 20

same thing as number 2, final answer cca. 26.9 = c3

According to the graph, what is the value of the constant in the equation below?
kow [346]

Option B: 50 is the value of the constant.

Explanation:

From the graph, the coordinates are (4,12.5) , (5,10) , (10,5) and (20,2.5)

Where the x coordinates denotes the width and the y - coordinates denotes the height.

Also, given that Height =\frac{ { Constant }}{{ Width }}$

We need to determine the value of the constant

<u>Value of the constant:</u>

The value of the constant can be determined using the formula,

Height \times weight=Constant

Since, all the coordinates lie on the same line, then all the coordinates have the constant.

Substituting the coordinate (4,12.5) in the above formula, we get,

4\times 12.5=Constant

       50=Constant

Therefore, the value of constant is 50.

Hence, Option B is the correct answer.

27 thousands 3 hundreds 5 ones times 10
Harrizon [31]

Answer:

27,050

Step-by-step explanation:

Thousand is three zeroes, so we start with 27,000

Hundred is two zeroes, so we add 300

Ones have no zeroes, so we add 5

27,305

but then this is times 10 which adds another zero, so our final result is

27,050
