Answer:
D. 14 cents
Step-by-step explanation:
At 10 feet for $7, that is 70 cents for every foot
At 20 feet for $13, that is 65 cents for every foot
At 50 feet for $28, that is 56 cents for every foot
At 100 feet for $57.50, that is 58 cents (rounded) for every foot
The best deal is 50 feet at 56 cents
The worst deal is 10 feet at 70 cents
So we do 70 - 56 = 14
So the answer is the savings per unit between the best deal and worst deal is 14 cents

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

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
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.
Evaluate the expression for v = 8

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
If there was only one government class, and Wes and Maureen were in that class of 38 students, what would be the probability that both Wes and Maureen would be selected as the two students to go to Washington? Is this still an example of independent events
The probability of an event is 1/19. Therefore, the given situation is not an independent event.
Given that, Wes and Maureen were in the government class of 38 students.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes
Total number of outcomes =38
Number of favourable outcomes = 2
So, probability =2/38
= 1/19
Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event.
The probability of an event is 1/19. Therefore, the given situation is not an independent event.

Triangle abc and xyz are congruent ,/_A is one half the size of /_B,/_y is 90° ./_c and /_z each have a measure of 45°.What is the measure of /_ a?
Answer:
∠a = 45°
Step-by-step explanation:
We are told that △abc and △xyz are congruent.
Thus;
∠a = ∠x
∠b = ∠y
∠c = ∠z
We are given;
∠y = 90°
Thus, ∠b = 90°
Now,we are told that ∠a is one half the size of ∠b.
Thus; ∠a = ½ × ∠b
∠a = ½ × 90
∠a = 45°

Topografía. La superficie de una montaña se modela mediante la ecuación ℎ(, ) = 5000 − 0.001 2 − 0.004 2 . Un montañista se encuentra en el punto (500, 300, 4390). ¿En qué dirección debe moverse para ascender con la mayor rapidez?
Respuesta:
(-1, - 2,4)
Explicación paso a paso:
Dada la función:
ℎ (x, y) = 5000 - 0,001x2 - 0,004y2
Tomando la derivada parcial con respecto a ambas direcciones (xey) se obtiene la dirección del vector de gradiente, donde es posible el movimiento más rápido
H '(x, y) = (dh / dx, dh / dy)
dh / dx = 2 (-0.001x) = - 0.002x
dh / dy = 2 (-0.004y) = - 0.008y
H '(500, 300) = (- 0,002 (500); - 0,008 (300))
H '(500, 300) = (- 1; - 2,4)
Por lo tanto, el montañista ascenderá con la mayor velocidad en el punto (-1, - 2.4)
