The radius of a circle is 11 feet. What is the circle's area? Use 3.14 for
Answer:
Formula for area of a circle;
A = πr^2
where pi is 3.14 in this case, and r is the radius squared
Plug in the actual values;
A = 3.14 x 11^2
A = 3.14 x 121
A = 379.94 square feet
Question 12 of 12 Use the volume formula to find the volume of the prism. A. 18 cubic units B. 4 1/2 cubic units C. 9 cubic units D. 7 cubic units
Answer:
C. 9 cubic units
Step-by-step explanation:
The formula for the volume of a prism is V=Bh, where B is the base area and h is the height. The base of the prism is a rectangle. The length of the rectangle is 4 and the width is 3/2 (1 1/2 = 3/2). The area A of a rectangle with length l and width w is A=lw
so the area of the base is 4 x 3/2 which is 6
then we multiply that by the height (3/2) to get 9.

list angles B,E,C, and D.
Step-by-step explanation:
Angles A and B form a linear pair, and are thus supplementary. Therefore, the measure of angle B is 180-105=75 degrees.
Angles E and F are a linear pair, and by the same logic, the measure of angle E is 70 degrees.
Since the sum of the measures of the angles in a triangle is 180 degrees, the measure of angle C is 180-75-70=35 degrees.
Since angles C and D are supplementary, the measure of angle D is 145 degrees.
Find the equation of the line shown
Answer:
Y = 1/2x + 1/2
Step-by-step explanation:
I'm not sure, but I think this is correct
Answer:
Slope intercept form;
y = mx + b
Where y is the independent variable and x is the dependent variable. 'm' represents the slope, and 'b' represents the y - intercept.
If we look at this graph:-
We can see that the line that intersects the y - axis is half of 1 which is 0.5, so that'll be our y-intercept.
It also rises one and goes over two so that'll be our slope.
To double check, we select two fixed points (1,1) and (3,2), we then divide the y-coordinates by the x-coordinates in the following order: (rise/run)
y2(second y-coordinate) - y1(first y-coordinate)
_____________________________________
x2(second x-coordinate) - x1(first x-coordinate)
2 - 1 1
_____ = ______, the slope is 1/2.
3 - 1 2
Now we format it in slope-intercept form:-
y = mx + b
y = 1/2x + 0.5
Where 1/2 is the slope, and 0.5 is the y-intercept
Rob deposits $1,000 in a savings account at New York State Bank that pays 1.4% interest, compounded monthly.
How much is in his account at the end of one year?
What is the APY for this account to the nearest hundredth of a percent?
Answer:
14
Step-by-step explanation:
p=$1000
rate percent=1.4%
time=one year
then
1.4/100*100=14
The amount of money in his account at the end of one year will be $1014.90. Then the APY for this account to the nearest hundredth of a percent will be 1.41%.
What is compound interest?A loan or deposit's interest is computed using the starting principle and the interest payments from the ago decade as compound interest.
We know that the compound interest is given as
[tex]\rm A = P \left (1 + \dfrac{r}{n} \right )^{t \times n}[/tex]
Where A is the amount, P is the initial amount, r is the rate of interest, and t is the number of years.
Rob deposits $1,000 in a savings account at New York State Bank that pays 1.4% interest, compounded monthly.
The amount of money in his account at the end of one year will be
A = 1000 × [1 + 0.014 / 12]¹²
A = 1000 × 1.01409
A = $1014.09
The APY for this account to the nearest hundredth of a percent will be
APY = [(1 + r/n)ⁿ - 1] x 100
APY = [(1 + 0.014 / 12)¹² - 1] x 100
APY = 1.41%

Hazel deposited $1,000 in her savings account. She earned 6.5% annual simple interest on the first $700 of her deposit and 3.5% simple interest on the remainder, How much interest did Hazel earn
after one year? (1 point)
O $45.00
O $51.00
O $56.00
O $65.00
Answer:
The answer is C. $56.00
Hazel earned $56.00 in interest after one year.
Step-by-step explanation:
700 x 6.5% =
700 x 0.065 = 45.5
300 x 3.5% =
300 x 0.035 = 10.5
45.5 + 10.5 = 56.00

a)use the statement above form an equation use the letter x for the uknown number
b) solve the equation
Answer:
see explanation
Step-by-step explanation:
(a)
let the number be x then doubling it is 2x and adding 11 is
2x + 11
(b)
the statement is equal to 25 , then
2x + 11 = 25 ( subtract 11 from both sides )
2x = 14 ( divide both sides by 2 )

Answer:
l = a + 3(p)
explanation:
upper length: a+ 4(p)

As we can see both of them have equal length.Therefore,
p + l = a+ 4(p)
l = a + 4(p) - p

Answer:
Answer: B. The law says you must write a new living will each time you re admitted to the hospital.
Explanation:
The law does not require that you make a new will whenever you are admitted to the hospital. Any existing will that has fulfilled the provisions of the law are biding unless the person decides to change the will of their own volition.
There is therefore no need to make a new will every time if there is already one in existence and the person is satisfied with it. The Registered Nurse should therefore correct this statement by the Licensed Practical Nurse.

Which number line shows the correct placement of 10%, 1/4, and 3/4?
Answer:
<-----10%-----1/4------3/4----->
The top left most answer (or A)
Step-by-step explanation:
Let's get all of these terms into the same representation. Meaning let's convert all of the numbers into either fraction or a decimal or percentage.
I find that fraction would be hard and so would percentage, lets try decimal.
1/4 = 0.25 as a decimal. (1/4 = 25/100 = 0.25) 3/4 = 0.75 (same manner as 1/4) Now for 10%. 10% in technical speaking is equal to 10/100 again which means it would be 0.10.
Okay so now they're all decimals let's put them in ascending order!
0.10, 0.25, 0.75. Yay! Now we can see on a number line the order would be
<-----10%-----1/4------3/4----->
