1 km = 1000 m and 1m = 100cm

1 km is the same as 1000 m = 1000 x 100 = 100000 cm

There are 862 kilometres so there is 862 x 100000 = 86200000 cm in 862 km.

What is measurement angle C?<br>

11Alexandr11 [23.1K]

So you know all angles in a triangle add to 180 degrees and you have x + 3x + 2x which adds to 6x so you do 180/6 to get x = 30 and c = 2x so you do 30 x 2 which is 60 degrees. Hope this helps :)

Please help!!!!!!!!!!

Answer:

104 ft^2

Step-by-step explanation:

Before we start, one thing to notice is the 90 degrees symbol at the corners. This lets you know a rectangle has four 90 degrees angle, which will help in the next step.

First, separate the shape to become three rectangles.

After you've done that, start with the first recantgle on the left.

The edges are 8 and 5. To find the area, you must multiple 8 by 5.

8 * 5 =40

The area is 40 for the first rectangle.

Next, we do the second rectangle to the right of the first one.

oThe edges are 6 and 4. We know it is four because the full length on the rectangle on the left is 8 and below the 6 ft is the place that says 4 ft. The 6ft line cuts to rectangle in half so the other edge will be 4 ft. (Hope that made sense )

Now we find the area of the second rectangle by multiplying 6 and 4

6 *4 = 24

Now we conclude with the third rectangle. We know one edge which is 5 and the other edge will be 8 because, at the opposite end, it tells us the length is 8.

Now we multiply 8 and 5.

8 * 5 = 40.

Now, the three numbers we have found are 40, 24, and 40. Our final step is to add up these three numbers from the rectangles we made to find the area.

40 + 24 + 40 = 104

The area will be 104 ft^2

I hope this explanation helped and have a good day!

A recently admitted class of graduate students at a large state university has a mean GRE verbal score of 650 with a standard de

hjlf

Answer:

The answer is below

Step-by-step explanation:

The z score is a score used to determine the number of standard deviations by which the raw score is above or below the mean, it is given by the equation:

$z=\frac{x-\mu}{\sigma} \\\\\mu=mean, \sigma=standard\ deviation,x=raw\ score\\\\for\ a\ sample\ n:\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }$

Given that μ = 650, σ = 50. To find the probability that 5 students who have a mean of 490, we use:

$z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{490-650}{50/\sqrt{5} } =-7.16$

From the normal distribution table, P(x < 490) = P(Z < -7.16) = 0.0001 = 0.01%

Since only a small percentage of people score about 490, hence the local newspaper editor should write a scathing editorial about favoritism

Write an equation/inequality to represent the description. *

KiRa [710]

Provided in the question, total number of people that can be accommodated in the theatre are 471.

Now, 254 people are seated
p is the number of people who can enter the theatre of the movie.

Then, according to the question there are two possibilities. The number of people is less than the total number of People who can be accommodated.

$1) \: p + 254 < 471$

Or, they can be equal to the number of people.

$2) \: p + 254 = 471$

Combining both the inequations, We get

$\boxed{ p + 254 \leqslant 471}$

So, the correct option is Option D

If 14 people show up to a cookout and you make 21 hot dogs, how many will you need to make if 105 people up? plz help

Rus_ich [418]

158 hot dogs will be prepared if 105 people show up

Step-by-step explanation:

14 people show up to make 21 hot dogs

We need to find how many hot dogs will be prepared if 105 people show up?

We will solve this problem using Unitary method

Solving:

14 people make hot dogs=21

1 person makes hot dogs = 21/14

105 people make hot dogs = 21/14*105

= 157.5 ≈ 158 hot dogs

So, 158 hot dogs will be prepared if 105 people show up
