The m<3 = (2x + 10) and m<6 = (3x-15) find the value of x, m<3 and M<6
9514 1404 393
Answer:
x = 25; ∠3 = ∠6 = 60°
Step-by-step explanation:
Angles 3 and 6 are alternate interior angles, so are congruent.
2x +10 = 3x -15
25 = x . . . . . . . . . . . add 15-2x
2x +10 = 2(25) +10 = 60
The measures of angles 3 and 6 are 60°.

Answer:
QR ≈ 16.2 ft
Step-by-step explanation:
Using the tangent ratio in the right triangle.
tan62° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{QR}{RP}[/tex] = [tex]\frac{QR}{8.6}[/tex] ( multiply both sides by 8.6 )
8.6 × tan62° = QR , then
QR ≈ 16.2 ft ( to the nearest tenth )
1) Let X represent the number of tires with low air pressure on a randomly chosen car. The probability of distribution of X is as follows:
X 0 1 2 3 4
P(X) 0.1 0.2 0.4 0.2 0,1
a) Find the probability of 1 tire with low air pressure P (1) =
b) Find the probability of more than 2 tires having low air pressure P (more than 2) =
c) P (all 4 tires) =
d) Compute the expected number of tires with low air pressure.
e) Compute the standard deviation for the number of tires with low air pressure.
Answer:
0.2 ; 0.3 ; 0.1 ; 2
Step-by-step explanation:
X 0 1 2 3 4
P(X) 0.1 0.2 0.4 0.2 0,1
a) Find the probability of 1 tire with low air pressure P (1) :
From probability distribution table Given :
P(1) = 0.2
b) Find the probability of more than 2 tires having low air pressure P (more than 2) =
P(x > 2) = p(3) + p(4)
P(x > 2) = 0.2 + 0.1 = 0.3
c) P (all 4 tires)
From the table :
P(x = 4) = 0.1
d) Compute the expected number of tires with low air pressure.
E(X) = Σx * p(x)
E(x) = (0*0.1) + (1*0.2) + (2*0.4) + (3*0.2) + (4*0.1) = 2

◯The US and South Vietnam reclaimed towns that were attacked.
◯President Johnson decided not to run for reelection.
◯Americans wanted the war to continue in Vietnam.
◯US confidence in winning the war was weakened.
◯Fighting communism was easy for troops in Vietnam.
Answer:
Its A, B, and D.
Step-by-step explanation:
The Tet Offensive considered a turning point in the Vietnam War because:
The US and South Vietnam reclaimed towns that were attacked.President Johnson decided not to run for reelection.US confidence in winning the war was weakened.What happen in Vietnam war?Troops from the United States and South Vietnam targeted North Vietnamese and Viet Cong hideouts in Cambodia and Laos.
Although being a military defeat, the Tet Offensive was a stunning propaganda win for communists. In fact, it is frequently regarded for changing the tide of the war in their favour.
As Viet Cong rebels invaded rural areas previously held by the South Vietnamese government, the South Vietnamese began to lose authority.
Despite tremendous deaths, North Vietnam secured a strategic triumph with the Tet Offensive, which represented a watershed moment in the Vietnam War and the start of the protracted, agonising American withdrawal from the region.

Trinian mailed a box to her aunt The base of the box was a square with a side length of 20 inches. The box was 10 inches tall. Which of the following was the volume of the box? A. 2.000 in В. 4,000 in 200 in D 1,350
Answer:
the shape of the box is a rectangular prism.The way to solve this is by using the formula V=l*w*h
we only have 20(l) and 10(h) so here's a clue it said that the base of the box was squared so the width would also be 10 in. so....

I like dogs but this question is a hard one.
Answer:
Work below
Step-by-step explanation:
49 total dogs.
36 more small dogs.
13 big dogs.
lol just realized today's school has sh*t wording and this question can be taken TWO ways. 36 more as in, 36 more dogs in total or 36 more small dogs than large dogs adding the amount of large dogs with this. this gives us 49.
the only way to get the x value (large dogs) and add this on top of the 36 (small dogs) and get 49 is to do 6.5 + 42.5 (36 + 6.5) this gives us 49.
Thanks guy in the comments for giving the second response, after some thinking i realized that i could also read it that way.
F** k today's hw and their wording
Answer:
6.5 Large Dogs
42.5 Small Dogs
Step-by-step explanation:
You simply do not have enough love for dogs to solve the question.
Luckily I have an extremely high affection for dogs so I can help.
S = amount of small dogs
L = amount of large dogs
S + L = 49
S = 36 + L
plug the second equation into the correct variable of the first equation so:
(36+L) + L = 49
36 +2L = 49
2L = 49-36
L = 6.5 *this doesn't make sense*
S = 42.5 *this also doesn't make sense*

→X x K i m 0 2 x XA tire on a vehicle has a diameter of 30in. As it moves down the
road it makes 50 full revolution. What is the approximate distance
it traveled?
Answer:
94.25 in
Step-by-step explanation:
In one revolution, the tire moves a distance equal to its circumference. If the diameter is 30 in, the radius is half of that, 15 in. Circumference is 2 pi times the radius:
[tex]C=2\pi r= 2\pi (15) = 30\pi \approx 94.25 \text{ in.}[/tex]
The sun causes changes to things on Earth. Think of an object you have observed before and after it was left out in the sun. Describe how it changed.
Answer: well i have put things like leather and it shrunk while it was out in the sun
Step-by-step explanation:
We want to study how the Sun affects things on Earth, I will give you two examples.
First, we know that the Sun radiates electromagnetic energy.
So if you left something in the Sun, its temperature will increase (as it receives the radiation) but more things can happen.
The first example can be a plant, that if it was inside at first, and then you put it in the sun for a while, you will for sure see a change in the plant contexture. This happens because the Sun gives energy to the plant (or the plant utilizes the radiation that comes from the Sun as energy).
Another example (and another phenomenon) can be a black shirt that is left in the Sun for several hours. The radiation (UV radiation particularly) affects the dye in the shirt by a process called photodegradation. Thus, the color of the shirt fades away.
So these are just two different examples of how the Sun affects things on Earth.

An angle measuring 28.3 radians is drawn in standard position?
In what quadrant will the terminal side of this angle lie?
Express your answer as a Roman numeral.
Answer:
The terminal side of angle will lie in thirds quadrant
Step-by-step explanation:
Given the angle is 28.3 degree radians
Converting it into degrees we get -
28.3rad × 180/π = 1621.471°
Total 360 degrees rotation in this angle
1621.471°/360 = 4
SO the remaining degrees 181.471
The angle grater than 180 lies in third quadrant.
The terminal side of angle will lie in thirds quadrant

Answer: y = -2x + 6
Slope-intercept form: y = mx + b, where m = slope and b = y-int
m = -2
(-1, 8) --> -1 = x₁, 8 = y₁
Based on the slope and given point, use oint-slope form, y - y₁ = m(x - x₁), to find the slope-intercept equation:
y - 8 = -2[x -(-1)]
y - 8 = -2(x + 1)
y - 8 = -2x - 2
y = -2x + 6
