Answer:
35mins
Step-by-step explanation:
Can you hear me now cost function: y=0.15x+50.75
24 Hour Calls cost function: y=0.9x+24.5
Set two equations equal to each other because we want to find the time (x value) that make the cost (y-value) equal
0.15x+50.75=0.9x+24.5
0.75x=26.25
x=35mins
solve each equation. show your work, or explain your reasoning. 1.-3x-5=16 2.-4(y-2)=12

Rewrite the expression in the form 5^n
(5^-8) (5^-10)
Answer:
Step-by-step explanation:
This problem is all about bases and exponents. Because we have a quotient and the bases are both 5's, that means that we can use the rule of exponents for quotients to rewrite and simplify:
That's the simplification as long as you are "allowed" to leave the exponent as a negative number.
Answer:
5^-18
Step-by-step explanation:
Law of exponents bases the same add the exponents keep the base.
5^(-8+-10)=5^-18
Sam will take four science tests this quarter. Her scores on three of the tests are shown below.
What does Sam need to score on the fourth test to ensure that she will have an average of 90% for all four tests?
Answer:
98%
Step-by-step explanation:
Test 1 - 83%
Test 2 - 91%
Test 3 - 88%
Test 4 - ?
If we use x to represent Test 4, we can create the following equation:
1/4 (83 + 91 + 88 + x) = 90
We find the average here by adding up the four test scores and dividing by 4.
Proceed to solve it:
1/4 (262 + x) = 90
262 + x = 360
x = 98
Therefore, Sam needs to get a 98% to have and average of 90% on all four tests.

What is Graph?The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.
Following the creation of a research question, data is continuously gathered through observation. The information is subsequently arranged, condensed, categorised, and visually portrayed.
In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.
Usually, data that varies over time is represented with a line graph.
Given:
Daryll is given $30 and spends $1.25 per day on basketball cards.
Larry is given $2 and saves $1.25 per day.
So, to find the same day for both from the graph.

Answer:
the answer is C because according to the graph, the y-intercept is -6 and the slope is 3.
slope is rise over run, so find a point thats directly on a corner of the grid (i chose the y-intercept) and then count to see how many lines are between that point and the next one that's directly on the lines. (it's (1, -3)) making the slope 3/1 or 3
Ben bought 2 shirts for $16 each, 3 pairs of socks for $2.50 a pair, and a pair of jeans for $37.75. If the sales tax rate is 6.5%, how much did he pay for his items, including tax?
$127.46

$82.27
$59.91
Answer:92.81

First, figure out how much it would be without tax.
(2*16=32) + (3*2.50=7.50) + 37.75 = 77.25
Then, multiply this number by your tax rate.
77.25*6.5 = 5.02
Lastly, add your original total with this tax amount for your answer.
77.25+5.02= 82.27
