Find length of the hypotenuse in a right triangle with legs of 8cm and 15 cm
Answer:
Step-by-step explanation:
h^2=x^2+y^2, in this case
h^2=8^2+15^2
h^2=64+225
h^2=289
h=17cm
Answer:
17 cm
Step-by-step explanation:
The Pythagorean Theorem: [tex]a^2+b^2=c^2[/tex] where a and b are the legs and c is the hypotenuse
Plug in the values of the legs
[tex]8^2+15^2=c^2\\64+225=c^2\\289=c^2\\c=\sqrt{289} \\c=17[/tex]
Therefore, the length of the hypotenuse is 17 cm.

Find the mean, variance, and standard deviation of the binomial distribution with the given values of n and p.
n = 80, p = 0.2
Answer:
mean =16
variance=12.8
standard deviation =3.578
Step-by-step explanation:
mean=np=80×0.2=16
variance= np(1-p)
=16(1-0.2)
=12.8
standard deviation =
[tex] \sqrt{12.8} [/tex]
=3.5777
=3.578

About 5/7 of the earths surface is covered with water. About 88957440 km squared is land. How much in km squared of the earths surface is covered in water?
Answer:
71 percent
Step-by-step explanation:
About 71 percent of the Earth's surface is water-covered, and the oceans hold about 96.5 percent of all Earth's water. Water also exists in the air as water vapor, in rivers and lakes, in icecaps and glaciers, in the ground as soil moisture and in aquifers, and even in you and your dog. Water is never sitting still.
The area of the earth's surface covered in water will be 63541028.57 square kilometres.

An item originally costs $175.00. The item is now on sale for 99.75. What percent is the sale price for the original price? Is this an example of percent increase or decrease? Explain how you know?
Answer:
Discount percent = 43% off
Discount amount (money saved) = $75.25
Step-by-step explanation:
To find the discount percentage:
List price ($175) minus the sale price ($99.75) then divided by the list price ($175) and multiplied by 100 to get the discount percent of 43%.
To find how much money was saved:
List price ($175) minus sale price ($99.75) to get the amount saved, which savings are $75.25 in this case.

Shelby leaves her house at 9:00am on her bike at a speed of 320 meters per minute. At 10:30 am, her brother, Colby leaves the house on his bike and tries to catch up with Shelby. Colby rides at a speed of 500 meters per minute. At what time will Colby catch up with Shelby?
Answer:
Step-by-step explanation:
320t=500(t-1.5)
320t=500t-750
-180t=-750
t=25/6
t=4+1/6 hours
So Colby catches up 4 1/6 hours after Shelby left. Since she left at 9am
9+4hours + 10 minutes. So they have travelled the same distance at 1:10pm

Write a slope intercept equation for this situation.
A computer technician charges $60 to come to your house and $18 for each hour he works.
Answer:
y = 18x + 60
Step-by-step explanation:
The slope intercept equation is:
y = mx + b
For this problem:
y will represent the total cost of the technician
m will represent cost per hour
x will represent number of hours
b will represent the initial cost
With this in mind, we can plug these into our equation
y = 18x + 60
Answer:
in slope intercept this would look like y = 18x + 60

a polygon has 10080° as the total interior angle how many sides has the polygon
The formula for the sum of the interior angles of a polygon is (n - 2) * 180. In this formula, N is the number of sides. So, to find the number of sides that a polygon with an interior angle measure of 10080 has, we'll set the formula equal to 10080.
10080 = (n - 2) * 180
Divide both sides by 180
56 = n - 2
Add 2 to both sides
n = 58
Hope this helps!! :)
Answer:
58 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is 10,080°
n = the number of sides
(2n - 4)90 = 10080
2n - 4 = 10080/90 = 112
2n = 116
n = 58.

Answer:
602.88in²
Step-by-step explanation:
Formula for finding the volume of oblique triangle is expressed as
A = πr²h
Given
radius r = 4in
height h = 12in
Substitute
A = π*4²*12
A = 3.14*16*12
A = 3.14 * 192
A = 602.88in²
Hence the area of the cylinder is 602.88in²

The temperature of a piece of metal was 32°C. It was then lowered into a glass of
hot water and the temperature of the piece of metal rose to 36°С. Find the
percentage increase in the temperature of the piece of metal.
Answer:
12.5%
Step-by-step explanation:
Given that,
Initial temperature of a piece of metal = 32°C
Final temperature of the piece of metal = 36°С
We need to find the percentage increase in the temperature of the piece of metal. The percentage increase in any value is given by the relation as follows :
[tex]\%=\dfrac{|\text{final value-initial value}|}{\text{initial value}}\times 100\\\\=\dfrac{36-32}{32}\times 100\\\\=12.5\%[/tex]
So, the required percentage increase in the temperature of the piece of metal is equal to 12.5%.
