Answer:
f(t) = 0.85(21,000)
Step-by-step explanation:
100% - 15% = 85% 0r in decimal form 0.85
0.85 x the original pricen 21,000
Answer:
the answer for this question is: f(t)=21,000(0.85)^t
Step-by-step explanation:
well since its asking what function represents the value, you have to convert the 15 percent into a decimal. so when you put the equation together you can see its 0.85.

m∠ABC = 3(3) + 33 = 42
The cost for the raw materials of marble countertops, can be represented by the function , where is the area of the countertops. The retail markup, can be represented by the function. Which function can be used to find the marked-up price of a marble countertop depending on the area?
Answer:
[tex]m(c(a)) = 4.8875a[/tex]
Step-by-step explanation:
The missing parameters are:
[tex]c(a) = 4.25a[/tex] --- Cost of marble countertops
[tex]m(c) = 1.15c[/tex] --- Cost of retail markup
Required
The cost of marked up price
This implies that we calculate m(c(a))
We have:
[tex]c(a) = 4.25a[/tex]
[tex]m(c) = 1.15c[/tex]
[tex]m(c) = 1.15c[/tex] can be written as:
[tex]m(c(a)) = 1.15*c(a)[/tex]
Substitute: [tex]c(a) = 4.25a[/tex]
[tex]m(c(a)) = 1.15*4.25a[/tex]
[tex]m(c(a)) = 4.8875a[/tex]
Hence, the cost of marked up price is: [tex]m(c(a)) = 4.8875a[/tex]
Tina has 3 quarters, 1 dime, and 6 nickels in her pocket.
Find the probability of randomly drawing a nickel?
Answer:
60%
Step-by-step explanation:
Tina has 3 quarters, 1 dime, and 6 nickels, or 10 coins in total.
They are asking for the probability of drawing a nickel (6 in total). Divide 6 from the total amount of coins:
6/10 = 0.60, or 60%
Tina has a 60% chance of drawing a nickel from her pocket.

Find the volume of the cylinder. Round your answer to the nearest hundredth.
9514 1404 393
Answer:
1763.01 m³
Step-by-step explanation:
The height of the cylinder will be ...
h = (18 m)sin(60°) = 9√3 m
The volume of the cylinder is ...
V = Bh
where B is the area of the end circle.
B = πr² = π(6 m)² = 36π m²
Then ...
V = (36π m²)(9√3 m) ≈ 1763.01 m³
The volume of the cylinder is about 1763.01 m³.

What is the measure of the reference angle for a -287° angle
The measure of the reference angle for a -287° angle is 17°.
To measure of the reference angle for a -287° angle
1. Determine the quadrant: First, we need to identify the quadrant in which the angle -287° lies.
- In the standard coordinate plane, angles between 0° and 90° are in the first quadrant, between 90° and 180° are in the second quadrant, between 180° and 270° are in the third quadrant, and between 270° and 360° are in the fourth quadrant.
- Since -287° falls in the third quadrant, we know that the reference angle will be found in the first quadrant.
2. Find the corresponding acute angle: To find the reference angle, we need to find the acute angle that has the same trigonometric values as the given angle.
- To do this, we can add 360° to the given angle (-287° + 360° = 73°). This gives us an equivalent positive angle in the same position.
3. Determine the reference angle: Now that we have the positive equivalent angle (73°), we can find the reference angle by subtracting it from 90° (90° - 73° = 17°).
Therefore, the measure of the reference angle for a -287° angle is 17°.

Triangle ABC is similar to triangle WYZ.
Determine whether the following statement is true or false.
sin(B)>sin(Y)
True
False
9514 1404 393
Answer:
False
Step-by-step explanation:
Corresponding angles in similar triangles are congruent. The similarity statement tells you angle B corresponds to angle Y, so those angles are congruent. The sines of congruent angles are identical.
sin(B) > sin(Y) . . . . FALSE
sin(B) = sin(Y) . . . . true

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

The circumference of the inner circle is 270.04 miles. What is the area of the shaded region?
area of a circle = [tex]\pi r^{2}[/tex]
circumference =[tex]2\pi r[/tex]
Okay so the center of the circle is the same for both of the circles lets take that value as m so the radius of the inner circle is 54 - m
we have the circumference of the inner circle which is 270.04 we can find the value of m using that
[tex]270.04=2\pi (54-m)\\270.04= 339.2-6.28m \\6.28m = 339.2-270.04\\m= 11.02[/tex]
the radius of the inner circle is therefore 42.98
and the full circle has a radius off 65.02
area of shaded region = area of full circle - area of inner circle
area of shaded region = [tex]\pi (65.02)^{2} - \pi (42.98)^{2}[/tex]
area of shaded region = [tex]13281.39 - 5803.4[/tex]
area of shaded region = 7478 rounded off to the nearest whole number
Suppose the TRMS basketball team scored 78 points by 2-point and 3-point baskets only. If 35 total baskets were made, how many 2-point and 3-point baskets were scored?
Answer:
the number of 2 point and number of 3 point be 27 and 8 respectively
Step-by-step explanation:
Let us assume the number of 2 point be x
And, the number of 3 point be y
Now according to the question
2x + 3y = 78
x + y = 35
Multiply by 2 in equation (2)
2x + 3y = 78
2x + 2y = 70
y = 8
So,
x = 35 - 8
= 27
Hence, the number of 2 point and number of 3 point be 27 and 8 respectively

Answer:
El pH del refresco es 3.42.
Step-by-step explanation:
Se puede calcular el pH del refresco usando la siguiente fórmula:
[tex]pH = -log([H^{+}])[/tex]
En donde:
[H⁺]: es la cocentración de los iones H⁺ de la solución
Entonces, el pH es:
[tex]pH = -log([H^{+}]) = -log(3.8\cdot 10^{-4}) = 3.42[/tex]
El resutlado obtenido nos permite concluir que ese refresco es ácido.
Por lo tanto, el pH del refresco es 3.42.
