Answer:
45
Step-by-step explanation:
∡L ≅ ∡M, given
ΔKLM is isosceles because base angles are congruent
KM ≅ KL and KM = KL
KL = 12
∡K =∡J = 60°, given
∡M = 180 -60 -60 , because sum of angles in a Δ is equal to 180°
∡M = 60
∡K =∡J =∡M = 60°
ΔKJM is is equilateral because all angles have the same measure.
KM = 12
KM = KJ = JM = 12 because the triangle is equilateral so all sides are equal
ML = 9, given
The perimeter of JKLM is the sum of the sides
P = ML +KL +KJ +MJ
P = 9 + 12 + 12 +12 = 9 +36 = 45

If b⊥c and b⊥d, then c ? d
Answers
Answer:
C and D are parallel
Step-by-step explanation:
If b⊥c and b⊥d, then that means that they are both parallel because they both have a 90 degree anglewith line B.
Answer:
| | (Parallel)
Step-by-step explanation:
I'm assuming that is what it is asking. if b and c are perpendicular, that means they form 90 degrees on all angles. The same for b and d. So if both c and d are perpendicular to b, then they are parallel.

A painter needs to paint the bottom of a circular pool. The pool has a radius of 30 feet. A store sells 5-gallon cans of paint. Five gallon of paint covers 1500 square feet. What is the smallest number of 5-gallon cans the painter must buy to cover the bottom of the pool?
Answers
Answer:
2 cans
Step-by-step explanation:
Given that :
Radius of pool = 30 feets
Using the relation for the Area of a circle :
Area = pi*r^2
Thus,
Area of pool = 3.14 * 30^2
Area of pool = 3.14 * 900 = 2826feet²
Paints are sold in cans of 5 gallon
5 gallon of paint = 1500 feet²
Least number of 5 gallon can required :
2826 feet² / 1500 feet² = 1.884 cans
Hence,
Least number of 5 gallon can required = 2 cans

If the domain of the function f(x)=2x^2-8 is {-2, 3, 5}, then the range is
Answers
Answer:
{0, 10, 42}
Step-by-step explanation:
The Domain acts like x and the Range acts like y and f(x) = y
f(x) = 2x^2 - 8
f(-2) = 2(-2)^2 - 8
f(-2) = 2(4) - 8
f(-2) = 8 - 8
f(-2) = 0
f(3) = 2(3)^2 - 8
f(3) = 2(9) - 8
f(3) = 18 - 8
f(3) = 10
f(x) = 2x^2 - 8
f(5) = 2(5)^2 - 8
f(5) = 2(25) - 8
f(5) = 50 - 8
f(5) = 42

48 people attended the Sunday matinee to watch a film. .Three over 8 of the people went to see a romantic comedy. .One over six of the people went to see an action movie. .The remaining people saw a horror movie. How many people saw a horror movie?
Answers
Answer:
22 people saw an horror movie
Step-by-step explanation:
Total people who attended the Sunday matinee = 48
People who saw romantic comedy = 3/8 of 48
= 3/8 × 48
= (3*48) / 8
= 144 / 8
= 18 people
People who saw action movie = 1/6 of 48
= 1/6 × 48
= 48/6
= 8 people
People who saw horror movie = x
Total people who attended the Sunday matinee = People who saw romantic comedy + People who saw action movie + People who saw horror movie
48 = 18 + 8 + x
48 = 26 + x
Subtract 26 from both sides
48 - 26 = 26 - 26 + x
22 = x
x = 22 people
22 people saw an horror movie

This year, Farah's car is worth $22,000. If the value of Farah's car decreases by 8%, what will her car be worth next year?
Answers
Answer:
$20,240
Step-by-step explanation:
Multiply 22,000 by 0.92% since if you subtract 0.08 which is equivalent to 8% from 1, you would need that percentage to get to your final answer which is $20,240.
Another option is to do the same thing except multiply 22,000 by 0.08% in which $1,760 is being cut off as it decreases. Subtract that number from $22,000 to get the same answer mentioned earlier.
Answer:
$20,240
Step-by-step explanation:
This is a simple interest formula.
$22,000*(8%/100%) = $1760
$22,000-$1760 = $20,240

HELP ME PLSSSSS I WILL GIVE YOU 100 POINTS!!!!!!!
Answers
Step-by-step explanation:
First we find the slope of f(x):
When x increases by 1, f(x) increases by 8. Slope of f(x) = 8/1 = 8.
Slope of g(x) = Coefficient of x = 3.
Therefore the slope of f(x) is greater than the slope of g(x).
When x = 0, f(x) = -1 (given ii the table) Therefore the y-intercept of f(x) is -1.
Y-intercept of g(x) = Constant term = -2.
Since -1 > -2, f(x) have a greater y-intercept.

What needs to be done to rationalize the expression 5 over 2 minus radical 3 so there will no longer be a radical in the denominator
Answers
Answer:
[tex]10+5\sqrt{3}[/tex]
Step-by-step explanation:
Given the expression: 5 / (2 - √3)
To rationalize the denominator, we multiply the numerator and denominator by the conjugate of the denominator. The conjugate of (2 - √3) is (2 + √3). Hence multiplying gives:
[tex]\frac{5}{2-\sqrt{3} }*\frac{2+\sqrt{3}}{2+\sqrt{3}} \\\\=\frac{10+5\sqrt{3} }{4+2\sqrt{3}-2\sqrt{3}-3 }\\\\Simplifying\ the\ expression:\\\\ =\frac{10+5\sqrt{3} }{1}\\\\= 10+5\sqrt{3}[/tex]
Hence: 5 / (2 - √3) = [tex]10+5\sqrt{3}[/tex]
