dog sled race extends 1049 miles, if a musher is twice as far from anchorage as from nome, how many miles has the musher completed, round to the nearest whole number. can anyone help.

Answers

Answer 1

Answer: His distance from one end is ' D ', and his distance from the other end is ' 2D '.

The distance from one end to the other end is (D + 2D) = 3D .

3D = 1,049 miles

Divide each side by 3 :

D = 1,049 / 3 = 349 and 2/3 miles .

The question doesn't tell which end he started from, and where he's headed,
so I guess you have to know that this is the Iditerod race, it STARTS in Anchorage,
and it ENDS in Nome.

He is ' 2D ' from Anchorage, so he has completed [ 2 x (349 and 2/3 miles) ] =
699 and 1/3 miles.

Rounded to the nearest mile, that's 699 miles.

$4 is what percent of $50

Answers

it is 8 percent of 50.

This is 1 way-
4/50=%/100 You now have a proportion. Cross multiply.
50%=400 Replace % with any variable.
50x=400 Now divide both sides of the equation by 50.
x=8

(% is basically the percentage of 4 of 50 over 100. its much easier to solve percentage problems when the percentages are over 100. 100 represents a full percentage.
example- 4 of 100 is 4% of 100)

2nd example-
Since the percentage can be found if over 100 as well (%/100), and since 100 is a multiple of 50, we can do 4 of 50 (which would look like 4/50) and multiply both numbers by 2 to get the percentage. These are our steps:

4/50× 2/2=
8/100

Therefore, 4 of 50 is 8% of 50

Susan tossed a die 630 times. Which of the following would be a good estimate of the number of times she got the number 3 on the die?A. 205
B. 118
C. 170

Answers

Assuming the die had 6 sides, there would be a 1/6 chance of getting the number 3.

630 / 6 = the theoretical amount of times you should get any number on the dice
630 / 6 = 105

105 is closest to B. The answer is B.

What is the intersection of plane WZVS and plane STUV?

Answers

Answer: The required intersection is the line 'VS'.

Step-by-step explanation: We are given to find the intersection of the planes WZVS and plane STUV.

We know that,

If two planes intersect each other, then their intersection is a straight line.

As shown in the given figure, the point 'V' and 'S' lie on both the planes WZVS and STUV.

So, the line joining these two points, i.e., the line VS also lie on both the planes.

Therefore, the intersection of both the planes is the line 'VS'.

Thus, the required intersection is the line 'VS'.

An easy way to find this is to look at the cross section, and see where the lines meet

If 28% of a sum is $100.80, what is the sum?

Answers

Call the sum S. Then, you can use the definition of percentage to obtain an equation to find the value of S: 1) 28% = 28 / 100; 2) 28% of x = (28/100)x; 3) that is equal to $100.80 => (28/100)x = 100.8 => x = 100.8 * 100 / 28 => x = 360. You can verify that the 28% of 360 is 100.80: 360 * 28/100 = 100.80. Then, the answer is $360.
