A store pays $147 for a skateboard. If the store marks it up 75%, then marks it down 22%. What is the new cost
Answer:
$200.65
Step-by-step explanation:
If they bought it for 147 then marked it up 75% you would do
$147+75% = 257.25
THEN they mark down
257.25 - 22% = $200.255 which would be
$200.25 orrr $200.26
Jim wants to buy a new tablet for his homework. His budget is $350. If the tablet costs $330 plus 4.5% sales tax, can he buy it for $350 or less?
Answer:
Yes, he can buy it for $350 or less
Step-by-step explanation:
330.00 x 4.5%
330.00 x 0.045 = 14.85
330.00 + 14.85 = 344.85
or
330.00 x 1.045 = 344.85

An experiment compares the height of two plants over time. A plant was 2cm tall at the beginning of the experiment and grew 0.5 centimeters each day. The functions f(t)=0.5+2 represents the height of the plant in centimeters after t days . Which plant for f, or g was growing faster ?
Answer:
Plant F;
Plant G;
Plant G
Step-by-step explanation:
Given that:
Plant F :
f(t)=0.5x+2
From the growth graph given for the second plant ; plant G
Point 1 (0, 5) ; point 2(16, 9)
Slope = Rise / Run = (9 - 5) / (16 - 0) = 4 / 16 = 0.25
Intercept = 5 ( point where fitted line crosses the y-axis)
Linear slope intercept relation : y = mx + c
m = slope ; c = intercept
g(x) = 0.25x + 5
The slope value of plant F = 0.5
Slope value of plant G = 0.25
F > G
Hence, F is growing at a faster rate
The starting height is given by the intercept value of the two equations ;
Plant F, intercept = 2
Plant G, intercept = 5
G > F
Hence, G was taller, to begin with
Height after 8 days :
x = 8
f(8)=0.5(8)+2
f(8) = 4 +2 = 6
g(8) = 0.25(8) + 5
g(8) = 2 + 5 = 7
Hence, G was taller after 8 days

Solutions 5x + 10 = 5x
Answer:
I think there is no solution to the equation. (I'm not sure what your asking)
Step-by-step explanation
The equation should equal 0, so you subtract 5x from both sides. Once you do that, it cancels out the 5x and leaves 10=0 which is a false statement.

If the interior angle of a convex polygon is 135 , the exterior angle is?
Answer:
45
Step-by-step explanation:
To find the exterior angle, you subtract the interior angle, which, in this case, is 135, by 180
So, 180-135=45 degrees

HELP NO LINKS Jesse wants to start driving himself to and from school each day his parents want to know how much driving time would be involved so Jesse surveyed for neighbors who live on his block and drive to school data he collected is displayed in the table below
175 minutes of driving time would be involved for Jesse according to the survey.
What are the basic rules of surveying?Some basic rules of surveying are:
Define a clear, attainable goal for your survey.Keep the more personal questions to the end. Don't let your survey get too long. Focus on using closed-ended questions. Consider including a survey incentive. Don't ask leading questions. Keep your answer choices balancedGiven, Jese wants to start driving himself to and from school each day He surveyed neighbors who live on his block and drive to school data.
For better understanding, a picture is attached below.
Add up the 8 different times then divide by 4 to get the average driving time for 1 day:
⇒ 12 + 18 + 13 + 21 + 15 + 22 + 15 + 22 = 138
⇒ 138 ÷ 4 = 34.5 mins
Now multiply the average drive time for 1 day by 5 to determine the time taken to drive to and from school for 5 days:
⇒ 34.5 x 5 = 172.5 minutes
As 172.5 ≈ 175 minutes, the nest response is 175 minutes
Therefore, According to the study, Jesse would require 175 minutes of driving time.

Use the annual compound interest formula to find the amount in the savings account at the end of the time period and then find the total interest earned.
$8,000 at 5% for 3 years.
It is one of these answers if it helps...
$12,700 in account $4,700 interest
$10,520 in account $2,520 interest
$8,315 in account $315 interest
$9,216 in account $1,261 interest
Answer:
$9,216 in account $1,261 interest.
Step-by-step explanation:
The compound interest is given by:
[tex]a = p(1 + \frac{r}{n})^{nt} [/tex]
P = Principal
r = rate
n = Number of times interest is compounded per unit t
t = time
so:
[tex]a = 8000(1 + \frac{0.05}{1} ) ^{1 .3} \\ a = 9261[/tex]
therefore, the answer is:
$9,216 in account $1,261 interest

Vincent has a box of popsicles. There are 12 cherry, grape 10 orange, and 6 blue raspberry If he reaches in the box and pulls one out at random, what the probability it will be blue raspberry?
Answer:
6:28 or 3:14
Step-by-step explanation:
if you add all the flavor amounts up, which is 12 + 10 + 6, you get 28. 6 of those 28 popsicles are blue raspberry, so the ratio is 6:28. if it needs to be simplified, its 3:14 because 6/2 is 3 and 28/2 is 14
Answer:
6:28 if you add all Popsicles it gives you 28,so the probability that he will pick raspberry are 6 ,so if you simplyfy further its 3:14
