Answer:
20x - 30 = 250
Step-by-step explanation:
20x - 30 = 250
20x = 280
x = 14
find the value of X for which m is parallel to n .
Answer:
x = 42
Step-by-step explanation:
the angles are considered congruent so the equation would be 4x-27 = 3x+15
add 27 to both sides: 4x= 3x +42
subtract 3x from both sides: x= 42
Two pulleys, one with radius r 1r1 and the other with radius r 2r2, are connected by a belt. The pulley with radius r 1r1 rotates at omega 1ω1 revolutions per minute, whereas the pulley with radius r 2r2 rotates at omega 2ω2 revolutions per minute. Show that StartFraction r 1 Over r 2 EndFraction equals StartFraction omega 2 Over omega 1 EndFraction r1 r2
Answer:
r1/r2 = 2ω2/ω1
Step-by-step explanation:
The velocity of each pulley is expressed as v = ωr where;
v is the linear velocity of the pulley
ω is the angular velocity of the pulley
r is the radius of the pulley.
For the two pulleys, the velocity I'd both pulleys are the same.
v1 = v2
v1 is the linear velocity of first pulley
v2 is the linear velocity of the second pulley.
v1 = ω1r1
v2 = 2ω2(r2)
r1 and r2 is the radius of pulley 1 and pulley 2 respectively.
Since v1 = v2
ω1r1 = 2ω2(r2)
Divide both sides by r2
ω1r1/r2 = 2ω2(r2)/r2
ω1r1/r2 = 2ω2
Divide both sides by ω1
ω1r1/r2/ω1= 2ω2/ω1
r1/r2 = 2ω2/ω1

Help, I’m stuck. Lol.
Answer:
a. height = 12
b. area = 228
Step-by-step explanation:
a. To find the height, we can use the triangle formed by the side that measures 15, the side that measures 9. and the height. The hypotenuse of the triangle(the longest side opposite of the right angle), is 15. We can then use the Pythagorean Theorem, which states that [tex]a^2+b^2=c^2[/tex], where c is the hypotenuse, and a and b are the two other sides. In this case, we need to find a leg of the triangle, not the hypotenuse. What do we do? We can first call the height a, and rearrange the Theorem into [tex]c^2-b^2=a^2[/tex]. [tex]15^2=225, 9^2=81,[/tex] and [tex]225-81=\sqrt{144}[/tex]=12. Therefore, the height of the parallelogram is [tex]\boxed{12}[/tex]
b. To find the area of the parallelogram, we can use the area formula, which is Base*Height. The base is the flat side. We can find the base by adding 9+10=19, and [tex]19\cdot12=\boxed{228}[/tex]

F&J Farms sells super egg-laying chickens that historically weigh on average 3 pounds with a standard deviation of 0.4 pounds. However, it has been discovered that the chickens actually weigh twice as much as they used to. What is actual the mean and standard deviation of the chickens?
Answer:
Mean of chicken = 6 pounds, Standard Deviation of chicken = 0.6 pounds
Step-by-step explanation:
Given : Chickens mean & standard deviation = 3 & 0.4 pounds respectively. Chickens considered weigh twice actually now.
If all numbers in the series are multiplied by a constant, the mean gets multiplied by that constant. So, new mean = 3 x 2 = 6
If all numbers in the series are multiplied by a constant, the standard deviation gets multiplied by that constant. So, new standard deviation = 0.4 x 2 = 0.8
IS THIS A FUNCTION, AND WHY
Answer:
Yes, it is a function

In parallelogram JKLM, what is the relationship between angle j and angle k?
j° + k° = 180°
j° = k°
j° = -k°
j° - k° = 180°
1 of 4
Answer:
since j&k are interior angles if I added they should come up to 180° so j + k is equals to 180° yeah that's the answer
Harry put blue and green marbles in a bag. Exactly 3/4 of the marbles in the bag are blue. Which of the following could be the total number of marbles in the bag.
A. 3
B. 6
C. 7
D. 8
Answer:
D
Step-by-step explanation:
Because when u multiply 3/4 times A,B,C it gives you a decimal, when u multiply 3/4 by 8 you get 6 a whole number.
The total number of marbles in the bag could be (d) 8
How to determine the possible total?We have:
Blue proportion = 3/4
This means that the green proportion is
Green proportion = 1 - 3/4
Evaluate
Green proportion = 1/4
Express as ratio
Blue: Green = 3/4 : 1/4
Simplify
Blue: Green = 3 : 1
Add the ratios
Total = 3 + 1
Total = 4
The above means that the total number of marbles in the bag is a multiple of 4
i.e. 4, 8, 12, 16, 20......
Hence, the total number of marbles in the bag could be (d) 8
