Answer:

852 miles

Step-by-step explanation:

We presume the speed is constant, so the satellite will travel 3/8 the distance in 3/8 the time.

... d = (3/8)·(2272 miles) = 852 miles

_____

1 minute is 1/8 of 8 minutes, so 3 minutes is 3/8 of 8 minutes.

Andrei [34K]

Answer:

The shorter side: longer side is 385:512

Step-by-step explanation:

We are given that A man has 166 feet of fencing to build the pen

We are supposed to find If one end is a square, find the outside dimensions, if a = 6.

Side of square = x

Perimeter of square = $4 \times side = 4x$

a=6

Length of rectangular part = x+a = x+6

Breadth of rectangular part = x

Perimeter of rectangular part = 2(l+b)=2(x+6+x)=2(2x+6)

So, ATQ

4x+2(2x+6)=166

4x+4x+12=166

8x=154

x=19.25

Shorter side = 19.25

Longer side = x+6=19.25+6=25.6

So, the shorter side: longer side = $\frac{19.25}{25.6}=\frac{385}{512}=385:512$

Hence the shorter side: longer side is 385:512

Given IQ scores are approximately normally distributed with a mean of 100 and a standard deviation of 15, the proportion of peop

weeeeeb [17]

The proportion of people with IQs above 130 is 2.3%.

<h3>How to calculate the value?</h3>

Normal distribution, is a probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean.

Here the mean is 100 and a standard deviation of 15.

µ = 100, σ = 15

P(X > 130) =

= P( (X-µ)/σ > (130-100)/15)

= P(z > 2)

= 1 - P(z < 2)

Using excel function:

= 1 - NORM.S.DIST(2, 1)

= 0.023 = 2.3%

The value is 2.3%.

The ray XZ is the angle bisector of ∠WXY and m∠WXY = 145°. Enter m∠WXZ. The measure of ∠WXZ is

Ganezh [65]

Answer:

72.5°

Step-by-step explanation:

Since, the ray XZ is the angle bisector of ∠WXY.

$\therefore m\angle WXZ = \frac{1}{2} \times m\angle WXY\\\\\therefore m\angle WXZ = \frac{1}{2} \times 145\degree \\\\\therefore m\angle WXZ =72.5\degree \\$
