X and 67° are supplementary (they equal 180) so to find x you do 180-67 which equals 113. So x=113°

Since 67 and y are vertical angles then y is 67

According to the histogram of travel times to work from the US 2000 census (Page 6 of "Journey to Work: 2000"), roughly what per

erastovalidia [21]

Histograms are used to represent data, where the length of each bar represents the frequency of the data element

The histogram is not given; So, I will give a general explanation.

Assume that the number of commuters that travel more than 45 minutes is 450, while the total number of commuters surveyed is 500.

The percentage of commuters that travel more than 45 minutes is the quotient of the commuters that travel more than 45 minutes and the total number of surveyed commuters.

So, we have:

$\%Percentage = \frac{450}{500}$

Divide 450 by 500

$\%Percentage = 0.9$

Express as percentage

$\%Percentage = 90\%$

Hence, the percentage of commuters that travel more than 45 minutes is 90%

The equation y= -5.131x^2 + 31.821x - 3.333 approximates the number of people standing in line to catch a commuter train x hours

GREYUIT [131]

The answer should be D since after 5 am to 7 am only two hours have passed so x=2, and then you plug in the x as 2 and solve it. You might get not around answer like 39.785 but when you round it, it would be 40.

A golfer takes two putts to get the ball into the hole. The first putt rolls the ball 10.3 feet in the northwest direction and t

creativ13 [48]

Let's put this on the usual Cartesian grid just so we can talk about it without drawing a picture. We'll use map conventions, right is east, up is north.

The ball starts at (0,0). 10.3 feet northwest means we have an isosceles right triangle whose diagonal is 10.3 feet. It's isosceles because northwest means equal parts north and west.

The sides of these triangles are in ratio $1:1:\sqrt{2}$ so the coordinates after the first putt are

$(- 10.3 / \sqrt{2}, 10.3 / \sqrt{2})$

The negative sign indicates west, which doesn't really matter for this problem. The distance from the origin to this point is 10.3 as required.

Now a second putt of 3.8 feet north puts us at

$(- 10.3 / \sqrt{2}, 10.3 / \sqrt{2} + 3.8)$

The squared distance to the origin is exactly

$d^2 = 10.3^2/2 + (10.3 / \sqrt{2} + 3.8)^2$

A little calculator work tells us

$d \approx 13.2621$

Third choice.
