Answer:
h=8
Step-by-step explanation:
a²+b²=c²
a=A
b=12
c=13
therefore substitute
A²+(12)²=(13)²
A²=13²-12²
A²=25
A=5
h=3+A
h=3+5
h=8
Answer:
8 ft
Step-by-step explanation:
since it is a right angled triangle and you have 2 side lengths, we use the pythagoras theorem here.
a² + b² = c²
the c² is always your hypotenuse (longest side of the triangle, also opposite to the right angles)
*the b and a doesnt matter which order you put it in*
so; (sub in the numbers to the formula)
a² + 12² = 13²
(rearrange - like terms together)
a² = 13² - 12²
(calculate it)
a² = 25
(simplify it - get rid of the ² on the a)
a = √25
(solve)
a = 5
so, we know that a = 5 and we know that we have an additional 3
5 + 3 = 8

where x = # of cupcakes sold
So if 1 cupcake was sold...
1.83 x 1 = 1.83 -75.00 = -73.17
And if 5 cupcakes were sold...
1.83 x 5 = 9.15 -75.00 = -65.85
In order to earn a profit they’d have to sell 41 cupcakes...
1.83 x 41 = 75.03 - 75.00 = 0.03 (the first non negative answer to this equation would only happen after 41 cupcakes are sold)

a rectangular computer screen has an area o A square inches. The width of the computer is 7 inches. Which equation rpresents x the length of the computer screen in inches
Answers
Answer:
x = A/7
Step-by-step explanation:
Given that the screen is rectangular, recall that the area A of a rectangle whose length is L and width is W is given as
A = L * W
Hence if the width is 7 inches and the length is x inches then the area which is A square inches is connected to both sides as
A = x * 7
Divide both sides by 7
x = A/7 inches

The sum of two consecutive odd numbers is 20 and their difference is 2. Find the two numbers
Answers
Answer:
9 and 11
Step-by-step explanation:
let the consecutive odd numbers be n and n + 2, then
n + n + 2 = 20
2n + 2 = 20 ( subtract 2 from both sides )
2n = 18 ( divide both sides by 2 )
n = 9 and n + 2 = 9 + 2 = 11

Answers
Answer:

Use the table to find the required data:
P(graduate) = Total graduates / Total studentsP(graduate) = 2610/10730*100% = 24% (rounded)The probability that a student selected at random is a graduate student is 31%.
What is probability?The probability of an event happening is represented by a number. The ratio of favourable outcomes to all outcomes is how probability is defined.
The total number of students is 6101, out of which 1879 are graduate students. Therefore, the probability that a student selected at random is a graduate student is:
P(graduate student) = number of graduate students / total number of students
P = 1879 / 6101
P = 0.3078
Therefore, the probability that a student selected at random is a graduate student is 31%.

4. The volume of a cylinder is 9.5 m cube, rounded to the nearest tenth of a cubic
meter. Which diagram shows the cylinder?
Answers
====================================================
Explanation:
You'll have to go through each answer choice one by one to check if those dimensions lead to to a volume of roughly 9.5 m^3
For choice A, we have a radius of 0.7/2 = 0.35 meters and a height of 6.2 meters. The volume of the cylinder is pi*r^2*h = 3.14*(0.35)^2*6.2 = 2.38483 which rounds to 2.4 cubic meters. We can rule out choice A because we want 9.5 as a result instead of 2.4
We follow the same steps for choices B through D. You should find that choice D is the answer because:
V = pi*r^2*h = 3.14*(1.4/2)^2*6.2 = 9.53932 which rounds to 9.5 m^3.
Note the 1.4/2 is dividing the diameter 1.4 in half to get the radius.

Proportion who would be traveling by car :
Number traveling By car / number of samples
p(car) = 23 / 75 = 0.30666
If total number of students = 1138
Using the proportion obtained from the sample, the number of students who would be traveling by car from the population would be :

Step-by-step explanation:
The average rate of change on the interval from 0 to 10 is 30
How to determine the average rate of change?The function is given as:
f(x)=3x^2-8
The interval is given as:
0 to 10
Calculate f(0) and f(10)
f(0)=3 *(0)^2 -8
f(0) = -8
f(10)=3 *(10)^2 -8
f(10) = 292
The average rate of change is then calculated as:
Rate = (f(10) - f(0))/(10 - 0)
This gives
Rate = (292 +8 )/(10 - 0)
Evaluate
Rate = 30
Hence, the average rate of change on the interval from 0 to 10 is 30
