We have to find the scale factor of 8 inches = 200miles.

To find the scale factor first we have to make the units equal.

Here we will convert miles to inches.

We know that 1 mile = 5280 ft.

And 1 ft = 12 inches.

So we can write that 1 mile = (5280)(12) inches = 63360 inches

Here 200 miles given.

So 200 miles = (63360)(200) inches.

= 12672000 inches.

Now the scale factor of 8 in = 200 mi is

8 in = 12672000 in

1 in = \frac{(12672000)}{8}

1 in = 1584000 in

So the scale factor is 1:1584000.

We have got the required answer.

A boy walks 58 feet up a ramp having a 22.5 degree inclination. how high is he standing from the ground?
yKpoI14uk [10]

Boy is 22.5 feet high from the ground

The six trigonometric ratios are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec). In geometry, trigonometry is a branch of mathematics that deals with the sides and angles of a right-angled triangle. Therefore, trig ratios are evaluated with respect to sides and angles.

The given question can be solved by sin, as value of perpendicular is to be evaluated and height and angle is provided. Let height from the ground be x

sin(22.5°) = x / 58

x = 58sin22.5 = 58(.38258)  =  22.5 feet high.

Thus the Boy is 22.5 feet high from the ground.

Is the data point, P, an outlier, an influential point, both, or neither?
telo118 [61]

I'd say an outlier. P is separated noticably from the other points and would not considerably affect the slope of the line

Evaluate. <br> 6[5(3-9)-1]+2/7(8-2)+4
GREYUIT [131]
If you would like to evaluate 6 * [5 * (3 - 9) - 1] + 2 / 7 * (8 - 2) + 4, you can calculate this using the following steps:

6 * [5 * (3 - 9) - 1] + 2 / 7 * (8 - 2) + 4 = 6 * [5 * (-6) - 1] + 2/7 * 6 +  4 = 6 * [- 30 - 1] + 12/7 + 4 = 6 * [- 31] + 12/7 + 4 = - 186 + 12/7 + 4 = - 182 + 12/7 = - 1274/7 + 12/7 = - 1262/7

The correct result would be - 1262/7.

Find the x and y intercept of 8x+10y=15. NO LINK TO ANSWER PLEASE TYPE
oee [108]

Answer:

x intercept: 15/8 and yintercerpt is 3/2

Step-by-step explanation:

to find y intercept you have to put equation in standard form.

10y=-8x+15

y=--4/5x+3/2

x intercept is when y=0, so we plug in 0

0=-4/5x+3/2

4/5x=3/2

x=15/8
