What could happen in March to make the net change in her account $0 from January to March?
A.
She withdraws $1,000 from her retirement account.
B.
Her retirement account value decreases by $1,000.
C.
She gets a loan of $1,000 from her retirement account.
D.
Her company puts a $1,000 bonus into her retirement account.
Answer:
D. Her company puts a $1,000 bonus into her retirement account.Step-by-step explanation:
Since the amount in the retirement account has decreased in February, she needs the increase by same amount, $1000 to make it same as in January.
It is possible by adding $1000, which is the Option D, all other options end up with $1000 less than in February.
find the volume of a cylinder whose circumference is 110 cm and height is 20 CM
Answer:
Volume is 19277.46 cm
Step-by-step explanation:
Data :
Circumference = C = 110 cm
Height = h = 20 cm
As circumference is
C = 2πr ⇒ r = C/2π = 110/2π =
r = 17.516 cm
Formula for volume of cylinder is
V = πr²h = π × 17.516 × 20
V = 19277.46

1)) An angle measures 144º more than the measure of its supplementary angle. What is the
measure of each angle?
Supplementary angles add to 180 degrees.
180 - 144 = 36
36/2 = 18
18 + 144 = 162
One angle is 18 and the other one is 162
Why is 45 minutes
equal to 3/4 of an hour?
1 hour = 60 minutes
45 min = (45 min)/(60 min) = 45/60 = 3/4 of an hour.
To go from 45/60 to 3/4, I divided both top and bottom by the GCF 15.
Answer:
45 minutes equal to 3/4 of an hour because, if you convert the one hour into minutes (60 minutes) it is divisible by 15 four times.
3 · 15 = 45.
What two numbers add and give you -4 and multiply and give you 5
Answer:
your answer would be: no number
Step-by-step explanation:
to get a positive 5, you have to multiply 2 negative numbers, which are -1 and -5. and negative -1 + -5 =-6. For you to get -4, the 5 would have to be -5, in this case, it's a +5.

NEED HELP
Step-by-step explanation:
as the first 2 lines show us : there is a linear relationship between minutes and words.
1 minute correlates to 250 words.
2 minutes correlate to 500 = 2×250 words.
so, we see, every minute represents 250 words.
therefore, 3 minutes (A) correlate to 3×250 = 750 words.
and 5 minutes (B) correlate to 5×250 = 1250 words.

solve the following equation 6/8 + 1 equals 26 - 2 x
Answer:
x = 97/8
Step-by-step explanation:
6/8 + 1 = 26 - 2x
6/8 + 8/8 = 26 - 2x
14/8 = 26 - 2x
14/8 - 26 = -2x
14/8 - 208/8 = -2x
-194/8 = -2x
194/16 = x
x = 97/8

Which statements are true? Select all that apply.
You can replace "a number" with a variable to represent an unknown value.
You can replace "sum" with an addition sign.
You can replace "sum" with an multiplication sign.
You can replace "one-third" with 1/3
The correct algebraic expression is 1/3 n
CHART IS BELOW
Answer:
You can replace "a number" with a variable to represent an unknown value.
You can replace "sum" with an addition sign.
You can replace "one-third" with 1/3.
Step-by-step explanation:
"the sum" means to add.
Let "a number" = x:
The sum of a number and one-third = x + 1/3.
You can replace "a number" with a variable to represent an unknown value.
You can replace "sum" with an addition sign.
You can replace "one-third" with 1/3.
Johnny bought an oil painting originally priced at $80 but on sale for 50% off. After 10% sales tax, what was the total cost?
Answer:
Step-by-step explanation:
A sales tax is never applied until money actually changes hands.
So you need to start by taking 50% off.
50% 0f 80 dollars = 50/100 * 80 = 4000/100 = 40
So the cost of the painting = 80 - 40 = 40
Now apply the sales tax
10% of 40 dollars = 10/100 * 40 = 400/100 = 4
The total cost = 40 + 4 = 44 dollars

A home has a triangular backyard. The second angle of the triangle is 4º more than the first angle. The third angle is 16° more than three times the first angle. Find the
angles of the triangular yard.
Answer:
32°, 36°, 112°
Step-by-step explanation:
All of the angles are described in terms of the first angle, so we can use a variable to represent that: x. The second angle is (x+4) and the third angle is (3x+16). As always, the sum of angles in a triangle is 180 degrees:
x +(x +4) +(3x +16) = 180
5x +20 = 180 . . . . . collect terms
5x = 160 . . . . . . . subtract 20
x = 32 . . . . . . . divide by 5
x+4 = 36 . . . . find the other two angles
3x+16 = 3(32) +16 = 112
The angles of the triangular yard are 32°, 36°, and 112°.
In the least-squares regression line, the desired sum of the errors (residuals) should be a) zero b) positive c) 1 d) negative e) maximized
Explanation:
The key word here is "desired". We wish to make the errors as small as possible. The smallest any individual error can get is 0. Adding the entire collection of zeros will sum in a total of zero.
An error of zero means we hit the mark exactly. The unfortunate reality is that error is going to happen, so we'll have some positive error values with any regression line (or curve). It's only when all points are on the same line is when we have zero error and perfect interpolation rather than regression.
Again, the question is asking about desired error and the ultimate goal is to make the error zero. The next best thing is to minimize it as small as possible.
