Tristi contributes a set percentage of her gross pay to a 401k account and will have a total of $133,473.00 by retirement. Tristi's employer also contributes a set percentage, which will increase her total to $262,612.00. What is the percent increase between the total without and the total with Tristi's employer's contribution? Round your final answer to the nearest whole percent. (1 point)
59%
63%
81%
97%
Answer:
97%
Step-by-step explanation:
I got 63% wrong :') it showed that 97% was right.
The percent increase between the total without and the total with Tristi's employer's contribution is 97% option (D) is correct.
What is the percentage?
It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that;
Tristi contributes a set percentage of her gross pay to a 401k account and will have a total of $133,473.00 by retirement.
Using the formula of percentage increase:
= [($262,612.00 - $133,473.00)/ $133,473.00] x 100
= 97 %
Thus, the percent increase between the total without and the total with Tristi's employer's contribution is 97% option (D) is correct.

Question 1 Answer choices. 76° 70° 72° 79° 82°
Question 2 Answer choices. x = 7 x = 8 x = 10 x = 9 x = 12
Applying the inscribed angle theorem, we have:
1. m∠ABC = 79°
2. x = 10
What is the Inscribe Angled Theorem?The inscribed angle theorem states that the measure of an inscribed angle = 1/2(measure of intercepted arc).
Thus:
1. Find m∠ABC:
m∠ABC = 1/2(measure of arc AC) [inscribed angle theorem]
Substitute
m∠ABC = 1/2(360 - 94 - 108)
m∠ABC = 79°
2. Find the value of x:
m∠DEF = 1/2(DF) [inscribed angle theorem]
Substitute
51 = 1/2(14x - 38)
2(51) = 14x - 38
102 = 14x - 38
102 + 38 = 14x
140 = 14x
10 = x
x = 10

What is the slope of the line through the points (10,4)and (7,3) write your answer in simplest form
Answer:
1/3
Step-by-step explanation:
to find the slope of two points the formula is (y2-y1)/(x2-x1) so if you plug in the numbers given into that formula you get (3-4)/(7-10), then simplifying that you get (-1)/(-3) and the negatives cancle out so you get 1/3
The slope is the inclination of a line and can be calculated by the ratio of the difference of y's coordinate to x's coordinate thus the slope of the line passing through points (10,4)and (7,3) is 1/3.
What is the slope?A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines . The slope could be positive or negative.
The slope of the lines passing through points (x₁, y₁) and (x₂, y₂) is,
⇒ (y₂ - y₁)/(x₂ - x₁)
As per the given points (10,4)and (7,3)
Slope = (3 - 4)/(7 - 10)
Slope = -1/-3 = 1/3
Hence "The slope is the inclination of a line thus the slope of the line passing through points (10,4)and (7,3) is 1/3".

Answer:
She bought 46 highlighters and was given 15 for free
Step-by-step explanation:
Divide 92 by 2, which gives you 46
46 is the number of ens you bought
next Divide 46 by 3 to calculate how many she was given for free
46 ÷ 3 = 15.333

Compare the behavior of exponential functions to the limits of their situations.
Answer:
see below:
Step-by-step explanation:
What is the behavior of exponential functions?
For exponential functions, we see that the end behavior tends to infinity really fast. The larger the growth factor, which is the base of the exponential function, the quicker we get to infinity.
The limit of an exponential function is equal to the limit of the exponent with same base. It is called the limit rule of an exponential function.
for a comparison lets look at the exponentila function y=[tex]x^{4}[/tex]
the graph of this would look very similar an x squared parabola and would of course be increasing at an exponential rate
the limit would be equal to infinity
[tex]\lim_{x \to \infty} x^{4}[/tex] since the limit is equal to the limit of the exponent we would simply get x to the power of infinity which is infinity
hope this helps! if there is a specific comparison you need comment on this

On Tuesday afternoon at camp, Tiana did archery and sailing before dinner. Archery started at 12:30 P.M. Tiana spent 55 minutes at archery and 55 minutes sailing. What time did sailing end?
Answer:
2:20 p.m.
Step-by-step explanation:
Let's start with what we know
Tiana starts at 12:30 and spends 55 minutes at archery and 55 minutes sailing.
This question wants us to find what time does sailing end. To find this, we add 12:30 with 55 minutes for archery, then another 55 minutes for sailing
So,
12:30 + 55 minutes = 1:25
Then,
1:25 + 55 minutes = 2:20
So, she will end sailing at 2:20 p.m.

Three siblings have decided to pool their money to buy their parents a gift for their anniversary. They need to save $224.50 in total. Each sibling has a different rate of pay and works a different number of hours. Nancy earns $10.70 per hour. • Marc earns $11.30 per hour and always works 5 more hours per week than Nancy. • Kara babysits and earns $9 per hour and always works 2 hours less per week than Nancy. How many hours in a week must each sibling work in order to reach their goal of $224.50?
The number of hours each sibling must work each week to reach their goal of $224.50 is as follows:
Nancy: 6 hoursNancy: 6 hoursMarc = 11 hoursNancy: 6 hoursMarc = 11 hoursKara = 4 hoursWeekly calculation and of work doneThe total amount of money that needs to be saved = $224.50
Total amount of money Nancy earn = $10.70 per hour.
Total amount of money Marc earn = $11.30 per hour
Total amount of money Kara earn = $9 per hour
Number of hours Nancy works = X hours
Number of hours Marc works = 5 + X hours
Number of hours Kara works = X - 2 hours
To calculate the amount each earn according to the number of hours they worked the following is carried out;
10.70(X) + 11.30( 5+X) + 9(x-2) = 224.50
10.70x + 56.5 + 11.30x + 9x - 18 = 224.50
Collect the like terms together
10.70x+11.30x+9x +56.5-18 = 224.50
31x + 38.5 =224.50
31x =224.50 - 38.5
31x = 186
X = 186/31
X = 6
Therefore Nancy works for 6 hours
Marc works for 5 + X = 5+6 = 11 hours
Kara works for x- 2= 6-2 = 4 hours

Change .4 to a fraction
4/9
Step-by-step explanation:
because it repeating the denominator would be 9 so 4/9.
To transform infinitely repeating decimals into fractions can be tricky but I will show you a trick that turns them into fraction form.
For one digit repeating starting at the 10th digit it is simply
[tex]\frac{n}{9}[/tex]
for 0.n repeating
In this case it would be 4/9
If the number is
0.nm repeating nm, the fraction would be nm divided by 99 and so on.
However if the number is 0.nm with only m repeating
then it would be (n+m-n)/90
This part is good to know and the trick is similar but for your case you do not need to know this or further extension of the underlined part.

David has $520 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax.
He buys a new bicycle for $303.93.
He buys 4 bicycle reflectors for $10.99 each and a pair of bike gloves for $25.25.
He plans to spend some or all of the money he has left to buy new biking outfits for $73.43 each.
Write and solve an inequality which can be used to determine xx, the number of outfits David can purchase while staying within his budget.
Answer:
520 - 303.93 - (10.99 * 4) - 25.25 - 73.43x ≥ 0
-
1) Parentheses
520 - 303.93 - 43.96 - 25.25 - 73.43x ≥ 0
-
2) Combine like terms
146.86 - 73.43x ≥ 0
-
3) Get the variable term alone
-73.43x ≥ -146.86
-
4) Divide to solve
x ≤ 2
** dividing by a negative number, the inequality sign flips **
ANSWER :
x ≤ 2
Step-by-step explanation:
303.93+(4×10.99 )+25.25+73.43x = 520
303.93 + 43.96 + 25.25 + 73.43x = 520
373.14 + 73.43x = 520
73.43x = 520 - 373.14
73.43x = 146.76
x = 146.76 ÷ 73.43
x = 2
