Answer:
y = a(.10) + 25
Step-by-step explanation:
Using the equation y = ax + b.
"$25 per month for unlimited calls in the country and $0.10 per minute for international calls."
The word "per" indicating that you are multiplying this.
The only variables being multiplied are a and x.
Thus, a is the amount of minutes, x is the cost of international calls and b is the cost of unlimited calls.
Find the equation of the linear function represented by the table below in the slope-intercept form.
x y
-3 -7
2 -2
7 3
12 8
Answer:
y=x-32
Step-by-step explanation:
y=mx+b where m is the slope and b is the y-intercept.
slope=change in y/change in x
=5/5
y=5x+b --> choose a random point
(7,3) ---> 3=5(7)+b=35+b
b= -32
y=x-32
PLz help me! We r doing semester finals and i need to get this lesson finished in 2 hours so i can get my grade up!
Answer:
$84
Step-by-step explanation:
1. If 20% is marked off, then you are selling it for 80%.
2. 455 * 80% = 364
3. Since you are finding the cost markup from 280, then 364-280=84
Kenzie buys hair scrunchies. The cost for 20 scrunchies is $3.00.
The cost, c, for scrunchies is proportional to the number, n, of scrunchies.
Create an equation using n and c.
________________________________________________
Kenzie has $7.25. What is the maximum number of scrunchies she can buy?
______________________________
Answer:
48
Step-by-step explanation:
20 scrunchies=3 dollars
7.25 dollars = ?
1 dollar=6.66666666
0.25 dollar=1.666666666666
7*6.66666666=46.666666
:)
Answer:
Kenzie can buy 48 Scrunchies
Step-by-step explanation:
You have to divide 3 by 20. (3/20) Which is also 1.5/10 and as a decimal, that is 15 cents. So one scrunchie is equivalent to 15 cents, which means how many times can you take .15 from 7.25 is how many scrunchies she can buy. So how many times does .15 go into 7.25? The answer is 48.3(repeating). So you have to round it down because if you round it up she needs more money.
I hope that helped :)

Answer:
7 to the power of 7 ( which is 823,543 )
Step-by-step explanation:
Why? well if 4+3 is 7 the exponent would be 7 to because if you look carefuly it says with an exponent of 2 + 5 and 2 + 5 is 7 so your exponent is 7.
I hope This is right!

help pls :) ... ....
Answer:
40°
Step-by-step explanation:
According to the Triangle Sum Theorem: The sum of the measures of the angles in a triangle will add up to 180°.
So with this, you need to add 70° and 70°.
You get 140°
Then to find the last angle, you will subtract the 140° by 180°.
180°-140° = 40°
Hope this helped! :)
Answer:
40
Step-by-step explanation:
First you add 70 and 70 together to get 140 then minus it by 180.
Then you will get 40 degrees as your answer.
Hope This Helps :)
Brett rented ice skates for 34 hour. The total cost was $5.25. What is the cost per hour of renting the ice skates?
Answer:
$0.15 per hour
Step-by-step explanation:
$5.25÷34=0.15441176
Round that to the nearest cent. Which would equal $0.15.
During a sale, a store offered a 15% discount on a TV that originally sold for $900. After the sale, the discounted price of the TV was marked up by 15%. To the nearest whole number, what percent of the original price was the price after markup?
==================================================
Explanation:
The customer saves 15%, but still pays the remaining 85%. The two percentages add to 100%.
85% of $900 = 0.85*900 = 765
After the 15% discount is applied, the customer would pay $765
---------
Then after the sale, the price is marked up by 15%
This means we'll multiply by 1.15 to indicate a 15% increase
1.15*765 = 879.75
Notice that we don't get back to the original price (900) even though we increased by the same percentage as before. This is because 15% of a smaller number is a smaller amount; ie we have a smaller increase compared to the decrease earlier.
---------
Afterwards, divide the value 879.75 over the original price of $900
879.75/900 = 0.9775
Move the decimal point two spots to the right to end up with 97.75%
That percentage rounds to 98% when rounding to the nearest whole percent.

Read the passage about Ötzi the Iceman.
Half an hour after Ötzi dined, the killer came along and shot him in the back from a distance of almost 100 feet. The arrow went under his left armpit . . . a wound that would have been quickly fatal and probably not treatable even in modern times, especially where it happened. By the angle of the wound, he was either shot from below and behind, or he had been bent forward when he was hit from above and behind.

Kenzie buys hair scrunchies. The cost for 20 scrunchies is $3.00.
The cost, c, for scrunchies is proportional to the number, n, of scrunchies.
Create an equation using n and c.
Kenzie can buy 48 Scrunchies
Step-by-step explanation:
You have to divide 3 by 20. (3/20) Which is also 1.5/10 and as a decimal, that is 15 cents. So one scrunchie is equivalent to 15 cents, which means how many times can you take .15 from 7.25 is how many scrunchies she can buy. So how many times does .15 go into 7.25? The answer is 48.3(repeating). So you have to round it down because if you round it up she needs more money.

Solve for x. Round to the nearest tenth, if necessary.
Answer:
[tex]\sqrt19[/tex]
Step-by-step explanation:
First we solve for the biggest triangle: using the Pythagorean theorem, (a^2 + b^2 = c^2) we put in the sides,
9^2 + b^2 = 10^2.
solve, 81 + b^2 = 100
then we subtract 81 from both sides. b^2 = 19, and the answer is [tex]\sqrt 19[/tex].
Now we know what the third side is, which is the hypotenuse for the smaller triangle, so we use the Pythagorean theorem again.
4^2 + x^2 = 19.
Solve
16 + x^2 = 19
Subtract 16 from both sides
x^2 = 19
and finally, we take the square root of both sides
x = [tex]\sqrt19[/tex]
An employee earns a 25% commission rate on his sales. One day, he earned $175. What was his amount of sales?
Help Please
Answer:
$700
Step-by-step explanation:
25% = 1/4
the sales would be 100% or 4/4
So if commission rate is 1/4, to find the sales we multiply this by 4:
$175*4= $700
The sales would amount to $700
Hope this helps :)

A garden hose was left on in a yard and spilled 78 gallon every 23 minute. Find the average number of gallons spilled per minute.
Answer:
3.391 Gallons Per Minute
Step-by-step explanation:
78/23=3.391
Round 3.391 to 3.4
Answer:
≈3.39130434783 gallons per minute
Step-by-step explanation:
The information we get is a ratio, describing how many gallons of water will be wasted in 23 minutes, expressed as:
[tex]78 : 23[/tex] OR [tex]\frac{78}{23}[/tex]
We will use the fraction, the denominator is representing the time, which in this case, is 23 minutes. We want to have the denominator as 1 to find how much water will be spilled in one minute, to do this, we can divide both the numerator and denominator by 23:
[tex]\frac{78/23}{23/23} \\ =\frac{3.39130434783...}{1}[/tex]
And of course, if there's a need to round, go ahead.
And please do not waste water!

the equation is y=mx + b. the m (or the thing that comes before the x in the equation) is your slope, the y intercept is the last number. if the last number is preceded by a minus sign, the intercept number is negative
Answer:
For example, number 1's slope is 5/3. On a graph, you would go up 5 (not in block, but in numerical value) and right 3. The y-intercept is -2. This is where your line starts on the graph.
Step-by-step explanation:
y=mx+b b= y-intercept y-intercept=where the line crosses the y-axis m=slope slope== rise/run or slope formula, m=y2-y1/x2-x1

Step-by-step explanation: Can I have brainliest?
Explain, in detail, how you know if these are equivalent.
Answer:
they are equivalent.
Step-by-step explanation:
to find equivalent fractions, we need to multiply the numerator and denominator of the first fraction by the same number. this creates an equivalent fraction. 5 goes into 15 3 times, and 8 goes into 24 3 times. this shows that if we multiply both the numerator and denominator of the first fraction by 3, then we end up with the second fraction, proving that they are the same. hope this helps!
