Find the rectangular coordinates of (7, 150°)
Answer:
The coordinates are (-7sqrt(3)/2, 7/2).
Step-by-step explanation:
The rectangular coordinates from polar coordinates is found by:
x = r*cos(theta)
y = r*sin(theta)
Substituting the given values, we get:
x = 7*cos(150 deg) = 7*(-sqrt(3)/2) = -7sqrt(3)/2
y = 7*sin(150 deg) = 7*(1/2) = 7/2
The coordinates are (-7sqrt(3)/2, 7/2).
I hope this helps! :)
In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 21% of your total grade, each major test is worth 24%, and the final exam is worth 31%. Compute the weighted average for the following scores: 90 on the lab, 98 on the first major test, 71 on the second major test, and 79 on the final exam.
Answer:
the weighted score is 82.03
Step-by-step explanation:
The computation of the weighted score is as follows
= Respective scores × respective test or exam and score
= 0.21 × 90 + 0.24 × 71 + 0.24 × 71 + 0.31 × 79
= 18.9 + 21.6 + 17.04 + 24.49
= 82.03
Hence, the weighted score is 82.03
We simply applied the above formula so that the weighted score could be come

Answer:
Option 1: 28 is the correct answer.
Step-by-step explanation:
The given expression for sum is:
[tex]\[ \sum_{n=1}^{4} {2n+2} = 1 \][/tex]
There will be four terms in the sum
We have to find the terms by putting n=1,2,3,4 as n=1 to 4
Putting n=1
[tex]=2(1)+2 = 2+2 = 4[/tex]
Putting n=2
[tex]=2(2)+2 = 4+2 = 6[/tex]
Putting n=3
[tex]=2(3)+2 = 6+2 = 8[/tex]
Putting n=4
[tex]=2(4)+2 = 8+2 = 10[/tex]
So the summation will expand to:
[tex]\[ \sum_{n=1}^{4} {2n+2} = 1 \] = 4+6+8+10 = 28[/tex]
Hence,
Option 1: 28 is the correct answer.
Karen has a cube that has a side length of 6 in. The net of the cube is shown.
Question: What is the surface area of the cube?
Answer:
[tex]Area = 216\ in^2[/tex]
Step-by-step explanation:
Given
[tex]L = 6[/tex] --- length
Required
Determine the surface area
The surface area of a cube is calculated as follows:
[tex]Area = 6L^2[/tex]
Substitute 6 for L
[tex]Area = 6 * 6^2[/tex]
[tex]Area = 6 * 36[/tex]
[tex]Area = 216[/tex]
Hence, the surface area of the cube is [tex]216in^2[/tex]
Using PEMDAS solve
22/2x3
Okay, let me help you.
PEMDAS is just order of operations. P - Parentheses, E - Exponents, M - Multiplication, D - Division, A - Addition, and S - Subtraction.
/ this symbol means to DIVIDE.
Since division is at the beginning of the equation, you start with 22 ÷ 2 x 3
Let's break this down...
2 x 3 = 6
22 ÷ 6 = 3.66... and on with the 6's.
The answer to this equation, is

helppp plzzzzz. a sum of money put out at compund interest in increased by Rs.180 at the end of first year and by Rs. 188.10 at the end of second year. find out the sum and rate of interest
9514 1404 393
Answer:
₹172.25 at 4.5%
Step-by-step explanation:
The growth factor is the ratio of the values at the end and beginning of the second year:
multiplier = 188.10/180 = 1.045 = 1 + 4.5%
The amount put out is the amount at the end of the first year, divided by this growth factor.
P = A/(1+r) = 180/1.045 = 172.25
The sum put out is ₹172.25, and the rate of interest is 4.5%.

Construct a circle graph that represents the following data concerning the monthly expenses for a family budget.
Category Percent
Housing 35 %
Food 14%
Clothing 17%
Entertainment 12 %
Auto 22%
Find the central angle for housing. If necessary, round to the nearest tenth.
Answer:
The circle graph is attached.
Step-by-step explanation:
a) Data and Calculations:
Monthly Expenses for a Family Budget
Expenses Percentage Degree
Housing 35% 130° (360° * 35%)
Food 14% 50° (360° * 14%)
Clothing 17% 60° (360° * 17%)
Entertainment 12% 40° (360° * 12%)
Auto 22% 80° (360° * 22%)
b) The result shows that Housing expense took more than one-third of the circle with auto expenses occupying the next biggest chunk of the circle. Clothing came third to occupy one-sixth of the circle, with food and entertainment trailing behind with less than one-sixth of the circle respectively.

Because if u look it says ten minutes an e has 220 so that equals to almost 3'500 dollars Im only in 7th grade good luck
Answer:
Step-by-step explanation:
Heya, the correct answer is David. The tricky part is the Hours and minutes difference. by dividing 360 by 6 we'll get 60. That equals an hour. Which is what the original answerer got wrong. So, If we divide 180 by 6 we get 30. So actually, there is an 8-number difference between Alex's and David's answers. With David being right. 22-30

Find the percentage of change round to the nearest cent whole percent if necessary state whether the percent of change is an increase or decrease
3 months to 5 months
5 to 10
$0.32 to $.37
Answer with explanation:
Percentage change = [tex]\dfrac{Change}{Previous\ value}\times100[/tex]
a) 3 months to 5 months
Change = 5 - 3 ( increase )
Percentage change = [tex]\dfrac{2}{3}\times100\%=66.67\%[/tex] , it is an increase .
b) 5 to 10
Change = 10-5 = 5 ( increase)
Percentage change = [tex]\dfrac{5}{5}\times100\%= 100\%[/tex], it is an increase .
c) $0.32 to $.37
Change = 0.37-0.32 = 0.05 ( increase)
Percentage change = [tex]\dfrac{0.05}{0.37}\times100\%=13.51\%[/tex], it is an increase .
