a=1/2pa, solve for p
NO LINKS PLEASEE!! IM BEGGING YOU NO LINKSS!!!
Answer:
A = (1/2)Pa = Pa/2
You can multiply both sides by 2 to eliminate the fraction on the right side:
2A = 2(Pa/2) = Pa
Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:
(2A)(1/a) = 2A/a = (Pa)(1/a) = P
Rewriting:
P = 2A/a
You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.
Step-by-step explanation:
ik its so simple i just cant figure it out ;-; pls help
Answer:
what are we looking for?
I'm not exactly sure what you need to find so I'll just put this:
If you need to find the area:
A = l x 2
A = 11 x 7.7
A = 84.7 cm^2
If you need to find the perimeter:
P = 2(l + w)
P = 2(11 + 7.7)
P = 22 + 15.4
P = 37.4 cm
Note: It's okay to ask for help when you need it, even if your task is easy! :)

Find the missing side length of the right triangle
using the Pythagorean Theorem or PT converse.
A) 32 cm
B) 21 cm
C) 73 cm
D) 56 cm
Answer:
The answer is D) 56 cm
Step-by-step explanation:
Using the Pythagorean Theorem, you would first have to multiply 65 x 65 to get 4225 and multiply 33 x 33 to get 1089. Then, for the last step, you will have to solve this little equation: 4225= 1089 +? To do this, you will have to subtract 4225 - 1089 = 3136. Finding the square root, you will finally get your answer of 56 cm.

Step-by-step explanation:
Money was placed in a savings account and earned 3/4 % interest paid annually. Samantha, Tony and Anuyia each wrote an equation to show the amount of money in the account after one year with a balance of M dollars. T represents the total amount of money in the account.
Samantha’s Equation: T = 1.075M
Tony’s Equation: T = M + 0.0075M
Anuyia’s Equation: T = M(1 + 0.0075M)
Since none of the equations were written the same, they decided to see if their equations would give the same answers by using a $75 balance. Solve this problem using each student’s equation.

Answer:
1. mean:10 median:11 mode:13
2. mean:30 median:35 mode: 20
Answer:
1. Mean: 10 Median: 11 Mode: 13
2. Mean: 26.7 Median: 20.5 Mode: 20
Step-by-step explanation:
1. Mean: 6+7+11+13+13 = 50 then, 50/5 = 10
Median: 6, 7, 11, 13, 13 in the middle: 11
6- crossed
13- crossed
7- crossed
13- crossed
That leaves 11!
Mode: 13 appears two times. All the other numbers only appear once.
2. Mean: 0+20+20+30+40+70 = 160 then, 160/6 = 26.7 ( rounded to nearest tenth)
Median: 0, 20, 20, 30, 40, 70
0- crossed
70- crossed
20- crossed
40- crossed
20- crossed
30- crossed
They all are crossed, but the last 2 to be crossed are 20 and 30. The middle of those two numbers is 20.5 therefore, the median is 20.5!
Mode: 20 appears twice while the rest only appears once.
I hope this helps, good luck! :)

20 fans at a 49ers game are asked what their favorite team is.
Answer:
4) Unbiased; 5) Biased
Step-by-step explanation:
4) states that the audience of the poll was "random" people meaning it's a good foundation of data as they weren't chosen for the employee noticing their specific affiliation with being overjoyed with the product (as the question doesn't say) or for not liking (have complaints about it) the product.
5) The audience of the poll is fans of a sports team--definitely biased because they'll say they love the 49ers being a fan for them. Leads to skewed results not representing a portion of a population accurately.

Choose the inequality that represents the following graph
Answer:
Step-by-step explanation:
1) Check whether the graph is inclusive or exclusive. Inclusive graphs are equal to or greater/less than, whereas exclusive graphs are just greater/less than. A filled circle is inclusive, and a non-filled circle is exclusive. We see that in the graph, the circle is filled meaning it is inclusive. Secondly, we see that the number line goes forever when it is greater than(or equal to) 3. From these two pieces of information, we see that the answer is choice D.

SHOW YOUR WORK PLEASE!!
Answer: 31.42
Step-by-step explanation:
Find the value of x:
Answer:
x = 3
Step-by-step explanation:
These angles are vertical angles. Vertical angles equals to on another but on the opposite side. Since they equal to another you do:
(10x + 1) = (12x - 5)
Add 5 on both sides:
10x + 6 = 12x
Subtract 10x on both sides:
6 = 2x
Divide 2 on both sides:
3 = x
Answer:
(10x+1)°=(12x-5)°. [vertically opposite angle]
1+5=12x-10x
6= 2x
3=x
therefore,x=3
