Answer:
x = -36
Step-by-step explanation:
Add 12 to both sides
x - 12 + 12 = x
(12 cancels out)
-48 + 12 = -36
x = -36

Let's do this step by step!
The hyponteuse is 7.7 because it is the longest side of a 90 degree angle.
the formula for this would a^2 + b^2 = c^2
3.3^2 + b ^2 = 7.7^2
10.89 + b^2 = 59.29
- 10.89 - 10.89 subtract from both sides
b^2 = 48.4
[tex]\sqrt{b} = \sqrt{48.4} \\[/tex]
b = 6.95701085237
round to the nearest tenth ---> 7

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 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.
PLZZZ HELP ME...I AM FAILING THIS CLASS..if you can help me with ANY of these please do...i need all the work of how you got that answer..thankyou so much!!!
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
what is the sum 0 of -1
Answer:
If you mean 0 + (-1) then it's -1
