Answer:
1/2pi
Step-by-step explanation:
Since the formula for circumference is 2*pi*r and we know the R=1 so the of the whole circle is 2pi. This is a quarter of a circle so the answer is 1/2pi
Answer:
1/2pi
Step-by-step explanation:
The function f(x) = 3,189(1 + 0.05)x represents the amount of money in a savings account where x represents time in years. What does the 3,189 represent?

if you reflect any shape across the x-axis and then rotate it 180 degrees about the origin, do you get the same result that you would if you reflect it across the y-axis and then rotate it 180 degress about the orgin? what does that mean?
Answer: No the finished shapes would be in different quadrants
Step-by-step explanation:
Determine the constant of proportionality. Express your answer as y = kx
Time in minute (x) 6 4 10 5 9
Gallons of Water Used (y) 96 64 160 80 144
Every minute
gallons of water are used.
y=_x
Answer:
Y = 16x
Step-by-step explanation:
To find the constant, you do y divided by x. 96 divided by 6 is 16. To check your answer, 64 divided by 4 is also 16, as for the rest of the numbers. 16 is the constant of proportionality.
Hope this helps :)
Pls help me!! I don’t understand this
Answer:
Step-by-step explanation:
Since the two equations are parralel toeach other they equal each other, so you would solve for:
2x+4=4x-88
To solve this you can add 88 to each side resulting in 2x+92=4x
Then we would add 2x to both sides getting 92=2x
And then you divide both sides by 2, getting 46 degrees for x
(You can check this by plugging points in)
x=46
thats the answer

ASAP PLZZZZZZZZ HELP _____________ waves need a medium to travel, but _____________ waves do not.
Group of answer choices
sound; light
sound; electrical
light; sound
electrical; light
Answer:
Sound waves need a medium to travel, but light waves do not.
Step-by-step explanation:
Sound waves need a medium to travel because they cannot travel through a vacuum. This is because sound travels by producing vibration in the molecules of the medium surrounding it and there are virtually no molecules in a vacuum. Light doesn't need a medium through which to travel because the speed of light is experimentally constant.
Show your work step by step, please ASAP

Step-by-step explanation:
Step 8: Does the direction of the graphed line correspond to the sign of the calculated slope?
-Cannot determine, because the function is neither increasing nor decreasing.
-Yes, because the graph line points up and right and has a positive slope.
-No, because the graph line points down and right and has a positive slope.
-No, because the graph line points up and right and has a negative slope.
-Yes, because the graph line points down and right and has a negative slope.
Find all solutions to the equation 10x^2 - 7x - 6 = 0
Answer:
(2x + 1)(5x - 6)
Step-by-step explanation:
(2x + 1)(5x - 6)
2x + 1 = 0
Subtract 1 from both sides;
2x = -1
Divide both sides by 2;
x = -1/2
5x - 6 = 0
Add 6 to both sides;
5x = 6
Divide both sides by 5;
x = 6/5

Square the values in the bracket
PQ is parallel to RS
Use the diagram to findeasure of angle 2
Answer: 140
Step-by-step explanation: Since the lines are parallel, they have the same measured angles. Angle RS and angle PQ are both straight lines, meaning they are supplementary angles (180), and angle RA is 40 degrees, so you subtract 180(the total) by 40 to get the answer 140.

Bottles of water are on sale!
Did you get a good deal?
Solve this problem in your math notebook, and upload it to the assignment.
Answer: Less, 44 cents
Step-by-step explanation: The new price is 5/4 of a dollar and in decimal form would be 1.25. The old price is 1.69 dollars meaning the new price is a better deal. To find the difference we subtract 1.25 from 1.69 giving us $0.44
help me the images are posted
Answer:
28.
a. false
b. true
c. false
d. false
2. 8.4 X 2.3 X 2.09 = 40.3788
3. $10.04 - $13.47
4. Your friend would be incorrect because their decimal is in the wrong place. Take the decimals out of it and think about it. Can 1 times 2 equal anything near 31? no, so it's not reasonable that your friend could multiply 1.2 X 2.6 and get anything near 31.2
5. It is more reasonable to say between 5 and 6 because even when you round both of the numbers up (3 X 2), you still only get 6.

Answer:
to serve hot chocolate to 14 people, you need:
7/6 cups boiling water
12.25 cups milk
2 5/8 teaspoons vanilla
7/4 half & half cream
To serve cookies to 14 people you need:
2.4 (rounded) cups flour
7/8 teaspoon baking soda
7/16 teaspoon baking powder
7/8 cup butter
21/16 cups white sugar
Step-by-step explanation:
The regular recipe for hot chocolate serves 4 people. But 14 are being served; 14 is 3.5 times as much as 4, so multiply the measurements by 3.5.
The recipe for cookies makes 16 servings of 3 cookies (4 dozen total), so you must use slightly smaller quantities. 14 is 7/8 as much as 16, so just multiply the measurements by 7/8.
