Answer: The selling price will be $1.68
Step-by-step explanation:
If the magazine is marked-up by 12% , then you will multiply 12% by the amount of money then add it to the same amount of money.
1.50 * 12% = 0.18
1.50 + 0.18 = 1.68
In ΔPQR, p = 8.5 cm, q = 1.7 cm and r=7.7 cm. Find the measure of ∠R to the nearest degree
Answer: 57
Step-by-step explanation:
The value of the angle ∠r is equal to 56.63°.
What is trigonometry?The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry. The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.
Given that in ΔPQR, p = 8.5 cm, q = 1.7 cm and r=7.7 cm. The value of angle ∠r will be calculated as,
r² = p² + q² -2pqcos(r)
(7.7)² = (8.5)² + (1.7)² - 2 x 8.5 x 1.7cos(r)
59.29 -75.14 = -28.9cos(r)
cos(r) = 15.85 / 28.9
cos(r) = 0.55
r = cos⁻¹(0.55)
r = 56.63°

A plant currently measures 5.5 inches tall and will grow at a rate of 1 inch per week. Andrew wants to graph this information for his Science Fair project. If x represents the number of weeks and y represents the height of the plant, which choice below correctly describes the y-intercept in this relationship?
(5.5, 0)
(0,1)
(0, 5.5)
(1, 5.5)
Answer:
0, 5.5
Step-by-step explanation:
when they ask for a y-intercept, x is always zero, so now we eliminate two of the answers, and we will only have (0, 1) or (0, 5.5). At the beginning of the question it said a plant is currently at 5.5, so it started as 5.5 (0, 5.5)
so THE ANSWER IS (0, 5.5)

Answer:
Step-by-step explanation:
Hi! I'm lazy but I'll explain number two so you get the concept. 2x + y =10
Well, It says x = 5. When a number is next to another number like this: 5(6), it means multiplication. Same when a number and a letter are together like this: 2x. So that means it's 2 times 5, since 5 = x. 2 times 5 is 10. So what plus 10 equals 10 (10 + y = 10) The answer now is obviously 0. So that's how you do those equations! Hope u understand lol :>

Answer:
I think the whole Line would be 16
Step-by-step explanation:
You have to use the Pythagorean Theorem.
so do 6^2 + x^2 = 10^2
then solve and you get x^2 = 64 which means x=8
then since CE and ED are the same and congruent lines ED will also be 8 so you add the 8 up and get 16.

Given f(x) = ax + b/x,
f(1) = 1, and f(2)= 5, find constants a and b
Answer:
a = 3, b = - 2
Step-by-step explanation:
Given f(1) = 1 and f(2) = 5, that is
substitute x = 1 and equate to 1, substitute x = 2 and equate to 5
a + b = 1 → (1)
2a + [tex]\frac{b}{2}[/tex] = 5 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate a
- 2a - 2b = - 2 → (3)
Add (2) and (3) term by term to eliminate a
0 - [tex]\frac{3}{2}[/tex] b = 3
- [tex]\frac{3}{2}[/tex] b = 3 ( multiply both sides by - [tex]\frac{2}{3}[/tex] )
b = - 2
Substitute b = - 2 into (1)
a - 2 = 1 ( add 2 to both sides )
a = 3
Then a = 3 and b = - 2

A company makes paper labels for paint cans. As shown below, each can is in the shape of a cylinder with a height of 9in and a diameter of 8in. The paper label is wrapped around the can and covers only the side of the can (not the top or bottom). If the company makes 15 labels, how many square inches of paper will be needed? Use 3.14 for π, and do not round your answer.
Answer:
423
Step-by-step explanation:
Firstly we need to find the circumference of the circle.
Circumference = 2 × Radius with Pi
=2×8×3.14= 50.24
Now we must find the area of 1 label.
Area of 1 label= 3.14 × 9= 28.26cm²
Multiplying by the number of labels =
28.26 × 15
= 423.9 cm²
So, we'll just keep the answer 423 because we were asked how many square inches of paper will be needed.
