Ms. Ponse knows that only 44% of the pencils she
leis students borrow will be returned to her. She will
let students borrow 125 pencils in the second
semester. How many pencils can Ms. Ponse plan on
getting back?
Answer:
55
Step-by-step explanation:
44% * 125 = 0.44 * 125 = 55
Answer:
She can expect to receive back 0.44(125 pencils) = 55 pencils
Step-by-step explanation:
She loans out 125 pencils. If 44% will likely be returned, then 100% - 44%, or 56%, will not be returned.
She can expect to receive back 0.44(125 pencils) = 55 pencils

There are already 1,200 gallons of water in a swimming pool. If water is filling the pool at a rate of 30 gallons per minute, which expression indicates the amount of water, in gallons, in the swimming pool after m minutes?
Answer:
n = 30m + 1,200
Step-by-step explanation:
let n = gallons
m = minutes
There are 30 gallons per minute, so 30 is multiplied by the minutes, and because there are already 1,200 gallons of water, you add 1,200

Which expressions are equivalent to 64 Superscript 1? Check all that apply.
A) 4 cubed
B) 3 Superscript 4
C) 8 squared
D) 2 Superscript 8
E) 6 squared
F) 2 Superscript 6
Answer:
I believe it would be C, 8 squared.
Step-by-step explanation:
8 squared means to multiply 8 twice. Not by two, 8 times 8. If you do that, you will get 64. This means that 8 squared is equivalent to 64'1

NEED ASAP WILL MARK AS BRAINLIEST IF CORRECT
Answer:
2.16
Step-by-step explanation:
if x is seconds on the graph and y is the distance then you just look for what is y in the coordinate (6, _ ), in which the line on the graph shows it is 13
hope this helps!!
edit:
it seems i was incorrect, ahh im sorry
so you do have to divide the answer in the end, so 13/6 which is equaled to 2.16

Can anybody tell me what’s going on here?
Step-by-step explanation:
We are given a theta degree measure of sin in a specific interval. We are asked to find half of that degree measure.
The interval it ask us to find it in is between 2 pi and 5 pi over 2.
That is 360 degrees to 450 degrees. If you use reference angles, that is between the 0 degrees and 90 degrees. So that means our measure is going to be in the 1st quadrant.
Replace x with theta
[tex] \sin( \frac{x}{2} ) = + - \sqrt{ \frac{1 - \cos(x) }{2} } [/tex]
We dont know cos x but we can use the pythagorean trig theorem to find cos x.
[tex] \sin {}^{2} (x) + \cos {}^{2} (x) = 1[/tex]
[tex] \sin {}^{2} ( \frac{4}{5} ) + \cos {}^{2} (x) = 1[/tex]
[tex] \frac{16}{25} + \cos {}^{2} (x) = 1[/tex]
[tex] \cos {}^{2} (x) = 1 - \frac{16}{25} [/tex]
[tex] \cos {}^{2} (x) = \frac{9}{25} [/tex]
[tex] \cos(x) = \frac{3}{5} [/tex]
Cosine in 1st quadrant is positive so 3/5 is cos x.
Replace 3/5 for cos x.
[tex] + - \sqrt{ \frac{1 - \frac{3}{5} }{2} } [/tex]
[tex] + - \sqrt{ \frac{2}{10} } [/tex]
The answer is
[tex] + - \sqrt{ \frac{2}{10} } [/tex]

Options
1. 13
2. 15
3. 16
4. 18
Answer:
16 units.
Step-by-step explanation:
Using the hypotenuse formula (a^2 + b^2 = c^2) we can determin that AB and BC is 5 units long, now we add AB, BC and AC together and we get 16.

Drake owns 100 stocks of Balancia, Inc. He had bought these stocks at a face value of $10. The market price of these stocks is now $50 each.
Balancia has declared a dividend of 20% this year. Balancia's retained earnings for the year is $2,000,000 and it has 1,000,000 outstanding
stocks. What is the P/E Ratio?
Answer: 25
Step-by-step explanation:
The Price to Earnings ratio, AKA, the P/E ratio, is calculated by dividing the Market price of the stock by the Earnings per share.
Earnings per share = Net earnings for the year / Number of shares
= 2,000,000 / 1,000,000
= $2 per share
P/E ratio = Market price of shares/ Earnings per share
= 50 / 2
= 25

A shopper bought 7 ears of corn and 6 pounds of bananas and paid $5.15. At the same store, another shopper bought 4 ears of corn and 1 pound of bananas and paid $1.85 . What is the price of an ear of corn?
Please help!
Answer:
$0.70 per ear of corn
Step-by-step explanation:
Let c = Ear of corn
Let b = pound of bananas
First shopper:
7c + 6b = $5.15
Second Shopper:
4c + 1b = $1.85
Solve one equation for b since you are solving for c:
4c + 1b = $1.85
b = $1.85 - 4c
Substitute into other equation:
7c + 6b = $5.15 <--- b = $1.85 - 4c
7c + 6 ($1.85 - 4c) = $5.15
7c + $11.1 - 24c = $5.15
-17c + $11.1 - $11.1 = $5.15 - $11.1
-17c /-17 = -$11.85 /-17
c = $0.70 per ear of corn

cosx (2 sinx+1)=0
Answer:
x = pi/2 and 11pi/6
Step-by-step explanation:
Given the trigonometry expression
cosx (2 sinx+1)=0
This can be written in two forms as;
cosx = 0 and 2sinx + 1 = 0
If cos x = 0
x = arccos0
x = 90degrees
x = pi/2
Similarly
2sinx + 1 = 0
2sinx = -1
sinx = -1/2
sinx =-0.5
x = aarcsin(-0.5)
x = -30
Since sin is negative in the third and 4th quadrant
x = 270 + 30
x = 330degrees
x = 330pi/180
x = 11pi/6
