Answer:
The percentage increase is 78.72%
Step-by-step explanation:
Here, we want to calculate a percentage increase
We proceed to use the mathematical relation as follows;
Percentage increase = (new value - old value)/old value * 100%
new value is value in 2011 = 252
old value is value in 2006 = 141
Substituting these values, we have;
(252-141)/141 * 100%
= 111/141 * 100%
= 78.72%
Students in elementary school attends school five days each week after three weeks of attendance each student has attended school for a total of 6300 minutes for how many hours each day does each student attend the school
Answer:
Step-by-step explanation:
first lets meake the minutes into hours by dividing our minutes into hours
6300 / 60 = 105
so in total they go 105 hours in 15 days (5 days for 3 weeks is 15 days)
to find how many hours in each day lets divide our hours into the 5 days
105 / 15 = 7 hours a day

The weights in pounds of 6 members of a basketball team are 125, 136, 150, 119,
and 143. Find the mean and the median *
Answer:
Mean:(137.2)
Median:(139.5)
Step-by-step explanation:
Mean = (125+136+150+119+143) divide by six(6)
= 823/6 = approx 137.2
Median = for the median, you will arrange the numbers in other. from smaller to the bigger number.
119,125,136,143,150, 150. so 136 & 143 is the middle number.
so you will add the middle number and divide by 2.
that is 136+143/2 = 139.5.

b. Mills works as a construction worker. He makes a salary of 54,200 a year. After
this year his boss decided to give him a 3.5% raise. What is his new salary?
Answer:
$56,097
Step-by-step explanation:
First, we have to figure out how much his raise was, so we can convert 3.5% directly to a decimal:
3.5% = 0.035
Then we find
3.5% of 54,200 = 0.035 x 54,200 = 1,897
1,897 + 54,200 = 56,097
So, Mills new salary is $56,097
hope this helps:)

How to make a simplified expression for 4(y + 3) - 5
Answer:
4y + 7
Step-by-step explanation:
Simplify. Use the distribution method, and follow PEMDAS.
PEMDAS is the order of operation. It stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
Distribute 4 to all terms within the parenthesis. In this case, you are multiplying 4 to all the terms:
4(y + 3) = (4 * y) + (4 * 3) = 4y + 12
Next, combine like terms (terms with the same amount of variables);
4y + 12 - 5
4y + (12 - 5)
4y + 7
4y + 7 is your simplified expression.

An angle θ on the unit circle has a sine of 14. What is the value of cosθ?
Given:
An angle θ on the unit circle has a sine of [tex]\dfrac{1}{4}[/tex].
To find:
The value of cosθ.
Solution:
We have,
[tex]\sin \theta=\dfrac{1}{4}[/tex]
Since sinθ is positive, therefore, θ lies in first or second quadrant.
We know that,
[tex]\sin^2 \theta +\cos^2 \theta =1[/tex]
[tex](\dfrac{1}{4})^2+\cos^2 \theta =1[/tex]
[tex]\dfrac{1}{16}+\cos^2 \theta =1[/tex]
[tex]\cos^2 \theta =1-\dfrac{1}{16}[/tex]
Taking square root on both sides.
[tex]\cos \theta =\pm \sqrt{\dfrac{16-1}{16}}[/tex]
[tex]\cos \theta =\pm \dfrac{\sqrt{15}}{4}[/tex]
Therefore, the value of cosθ is either [tex]\dfrac{\sqrt{15}}{4}[/tex] or [tex]-\dfrac{\sqrt{15}}{4}[/tex].

Do values of these triangles form right triangles or not using Pythagorean theorem
Answer:
Yes
Yes
No
Step-by-step explanation:

From 1-10 You can see the numbers going from 0-8 on the left side except you repeat the number 4 twice then proceed. Then on the right side you do it backwards but instead you use the 2 times tables and you’re going to want to work your way from bottom to top and then when you reach to 0 which is the number 10 you repeat the 2 times tables again.
