Answer:

75 meters.

Step-by-step explanation:

In this case, you are trying to find side length NO. In accordance to SOH CAH TOA, you can use a sine function to find the missing side length, since you are given the hypotenuse.

sin(49) = x / 100

x = sin(49) * 100

x = 0.7547095802 * 100

x = 75.47095802

So, the closest answer would be 75 meters.

Hope this helps!

A company that manufactures and sells consumer video cameras sells two versions of their popular hard disk camera, a basic came

saul85 [17]

Answer:

The percentage of customers who buy an extended warranty is 33%.

Step-by-step explanation:

In this problem, we have these following percentages.

35% of the customers select the basic camera.

This also means that:

65% of the customers select the deluxe version. (Since you can buy only two versions of the hard disk camera and the sum of the percentages is 100%).

20% of those who select the basic camera also purchase the extended warranty.

40% of those who select the deluxe version also purchase the extended warranty.

What is the percentage of customers who buy an extened warranty?

$P = P_{1} + P_{2}$

$P_{1}$ is the percentage of those who buy the basic version with the extended warranty. So it is 20% of 35%. So

$P_{1} = 0.20*0.35 = 0.07$

$P_{2}$ is the percentage of those who buy the deluxe version with the extended warranty. So it is 40% of 65%. So

$P_{2} = 0.40*0.65 = 0.26$

$P = P_{1} + P_{2} = 0.07 + 0.26 = 0.33$

The percentage of customers who buy an extended warranty is 33%.

a skateboard ramp has a slope 2/5.Which is the angle the ramp makes with the ground? A.66 degrees B. Not here C.24 degrees D.22

vovikov84 [41]

We are given with the slope of a ramp that is equal to 2/5, that is x = 5 and y = 2. In this case, we can find the angle of elevation by using the formula: tan Ф = y/x
using a calculator (inverse tangent or arctangent), Ф = 21.8 degrees. In this case, the answer is D. 22 degrees.

A circle in the xy-plane is centered at (3, 0) and has a radius with endpoint (1, 8/3 ). Which answer choice is an equation of t

gayaneshka [121]

Answer: (x - 3)² + y² = $\frac{100}{9}$

Step-by-step explanation:

Circle Formula: (x - h)² + (y - k)² = r² ; (h, k) is the center & r is the radius

Use the distance formula for (3, 0) and (1, $\frac{8}{3}$ )

$r = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

$r = \sqrt{(3-1)^{2}+(0-\frac{8}{3})^{2}}$

$r = \sqrt{(2)^{2}+(-\frac{8}{3})^{2}}$

$r = \sqrt{4+\frac{64}{9}}$

$r = \sqrt{\frac{36}{9}+\frac{64}{9}}$

$r = \sqrt{\frac{100}{9}}$

$r = \frac{10}{3}$

****************************************************

Center (h, k) = (3, 0) Radius (r) = $\frac{10}{3}$

(x - h)² + (y - k)² = r²

(x - 3)² + (y - 0)² = ( $\frac{10}{3}$ )²

(x - 3)² + y² = $\frac{100}{9}$

How do i do KCF ? for 6th grade ;~;

Virty [35]

KCF

Keep

Change

Flip

lets say we are dividing 1/2 and 1/4. you would keep 1/2 the same, change the division sign to a multipluction, and flip 1/4 so that it becomes 4/1. you would then just multiply 1/2 and 4/1
