Answer:
x = -7
Step-by-step explanation:
-2x + 1 = -x + 8
* isolate the variable using inverse operations *
step 1 add 2x to each side
-2x + 2x cancels out
-x +2x = x
now we have 1 = x + 8
step 2 subtract 8 from each side
8 - 8 cancels out
1 - 8 = -7
we're left with x = - 7

A house is located at the center of a circular lot, exactly 25 yards from the edge of the lot. How much fencing will the homeowner need to surround the entire lot?
A. 157
B. 200.96
C. 185
D. 78.5
The number of yards fencing the homeowner need to surround the entire lot is 78.5 yards. Therefore, the option D is the correct answer.
What is the circumference?The circumference is the length of any great circle, the intersection of the sphere with any plane passing through its centre. A meridian is any great circle passing through a point designated a pole.
Given that, a house is located at the center of a circular lot, exactly 25 yards from the edge of the lot.
Here, d = 25 yards
Radius = 25/2 = 12.5 yards
We know that, the circumference of a circle = 2πr
= 2×3.14×12.5
= 78.5 yards
Therefore, the option D is the correct answer.

A satellite in a 100-mile-high circular orbit around Earth has a velocity of approximately 17,500 miles per hour.If this velocity is multiplied by √2 the satellite will have the minimum velocity necessary to escape Earth's gravity and will follow a parabolic path with the center of Earth as the focus.
Required:
Find the distance between the surface of the Earth and the satellite when θ = 50°.
a. Distance between surface of Earth and satellite:4496 miles
b. Distance between surface of Earth and satellite:4322 miles
c. Distance between surface of Earth and satellite:1286 miles
d. Distance between surface of Earth and satellite:643 miles
e. Distance between surface of Earth and satellite:1492 miles
Answer:
64.3 miles ( D)
Step-by-step explanation:
Circular orbit height ( from the center of the earth ) = 100 mile
angle between satellite and earth = 50°
escape velocity = √2 * 17500 = 24748.73 miles /hour
distance between surface of earth and satellite
x = cos ∅
∴ Cos ∅ = x / 100
x = cos 50° * 100 ≈ 64.3 miles

You have been given the task of finding out what proportion of students that enroll in a local university actually complete their degree. You have access to first year enrolment records and you decide to randomly sample 110 of those records. You find that 87 of those sampled went on to complete their degree. a)Calculate the proportion of sampled students that complete their degree. Give your answer as a decimal to 3 decimal places. Sample proportion
Answer:
The proportion of sampled students that complete their degree is 0.791.
Step-by-step explanation:
A proportion is the number of desired outcomes divided by the number of total outcomes.
a)Calculate the proportion of sampled students that complete their degree.
110 students sampled.
87 went on to complete their degree.
p = 87/110 = 0.791
The proportion of sampled students that complete their degree is 0.791.
5. A bag contains 5 blue marbles, 3 red marbles, and 2 yellow marbles. You select a marble at random. Wha
is Plyellow)?
2
8
5
5
Answer:
i cant rlly see the question bc its cut out but i yhink its 8
Step-by-step explanation:
total Amount of Marbles in the bag is:
5 + 3 = 8
So, since there are 5 Red marbles, the probability of drawing one is 5 / 8.
Now that you pulled that marble out, you have 7 marbles total left in the bag, 4 of those are read (5 originally, minus the one you took out.
So, the probability of the second round is 4/7.
To find the overall probability, you multiply those probabilities together:
4/7*5/8 = 20/56

Solve the following equation for x: 6(4x + 5) = 3(x + 8) + 3. Round to the nearest hundredth.
Answer:
x ≈ -0.14
Step-by-step explanation:
6(4x + 5) = 3(x + 8) + 3
24x + 30 = 3x + 24 + 3
24x + 30 = 3x + 27
21x + 30 = 27
21x = -3
x = [tex]\frac{-3}{21}[/tex]
x = [tex]-\frac{1}{7}[/tex]
