JL = 55, and
JK = 7x +4,
Find KL.
Answers
Answer:
30
Step-by-step explanation:
JL comprises of JK & KL. So ,
JL = JK + KL
Here the length of :-
KL= 9x + 3
JL = 55
JK = 7x + 4
So putting all the values above gives ,
7x + 4 + 9x + 3 = 55
=> 16x + 7 = 55
=> 16x = 55 - 7
= 48
=> x = 48/16 = 3
Using the value of x in finding the length of KL ,
KL = 9 × 3 + 3 = 27 + 3 = 30

Hey! I've had the same quiz earlier and these answers below are correct. Hope this helps you out and have a great day :)
We have proved that m∠ABC is an obtuse angle.
m∠ABC = m∠ABD + m∠DBC
100° = 60° + 40°
Given,
m∠ABD = 60°
m∠DBC = 40°
We need to prove that m∠ABC is an obtuse angle.
What is an obtuse angle?The angles greater than 90 degrees but less than 180 degrees are called obtuse angles.
We have,
From the figure.
m∠ABD = 60°
m∠DBC = 40°
We see that
m∠ABC = m∠ABD + m∠DBC
m∠ABC = 60° + 40°
m∠ABC = 100°
m∠ABC is greater than 90 degrees and less than 180 degrees so,
m∠ABC is an obtuse angle.
Thus we have proved that m∠ABC is an obtuse angle.

A study of class attendance and grades among first-year students at a state university showed that in general students who attended a higher percent of their classes earned higher grades. Class attendance explained 81% of the variation in grade index among the students. What is the numerical value of the correlation between percent of classes attended and grade index
Answers
Answer:
r = 0.9
Step-by-step explanation:
Correlation is denoted by r. r² is usually used to measure variation along the line as a fraction of the total variation.
We are told class attendance explained 81% of the variation in grade index among the students. Thus, for this regression, the variation is;
r² = 81%
Or r² = 0.81
Thus, the numerical value of the correlation r would be;
r = √0.81
r = 0.9

Answers
Answer:
-2 (6x - y) = -12x + 2y
Step-by-step explanation:
By using the distributive property, you start by multiplying -2 and 6x which gets you -12x. You then multiply -2 and -y (in other words -y = -1y) so, -2* -y would get you 2 as a negative multiplied by a negative is a positive. So, adding them together would get your final answer: -2 (6x - y) = -12x + 2y

A typical household pays about $1200 a year on energy bills, and the U.S. Department of Energy estimates that 46 percent of this energy is used for heating and cooling, 15 percent for heating water, 15 percent for refrigerating and freezing, and the remaining 24 percent for lighting, cooking, and running other appliances. The heating and cooling costs of a poorly insulated house can be reduced by up to 30 percent by adding adequate insulation. If the cost of insulation is $220, determine how long it will take for the insulation to pay for itself from the energy it saves.
Answers
Answer: 16 months or 1 and half year.
Step-by-step explanation:
given data:
46 percent of this energy is used for heating and cooling.
15 percent for heating water.
15 percent for refrigerating and freezing.
and the remaining 24 percent for lighting, cooking, and running other appliances.
Solution:
if the family spent $1200 on yearl bill, the cost of energy used in heating and cooling
= 46/100 * $1200
= $552 yearly.
by adding insulation the cost of heating and can be redu up to 30percent.
= 30/100 * $552
= $165.6.
if $220 determin how long it would take for the insulation to pay for it self from the energy it saves.
$165.6 would be saved yearly, this makes it an average of $13.8 saved monthly.
to determine the time it would take to settle the cost of insulation from energy saved
= $220/13.8
= 15.9 months
which Is approximately 16 months or 1 and half year to pay for the insulation.

Solve for the given variable. List the step used to solve the equation. 49.75 + 4.99x = 9.99x + 19.75?
Answers
Answer:
x=-2
Step-by-step explanation:
9.75+4.99x=9.99x+19.75
Simply Both Sides(change the order of 9.75 and 4.99x in this case)
4.99x+9.75=9.99x+19.75
Subtract 9.99x from both sides
4.99x+9.75−9.99x=9.99x+19.75−9.99x
−5x+9.75=19.75
Subtract 9.75 from both sides now
−5x+9.75−9.75=19.75−9.75
−5x=10
Divide both sides by -5 and boom
−5x/-5=10/-5

If h(x) = 2x - 1 and g(x) = 3x + 1, what is (h o g)(2)?
Answers
Answer:
Step-by-step explanation:
g(2) = 3(2) + 1 = 6 + 1 = 7
h(7) = 2(7) - 1 = 14 - 1 = 13
Using composite functions, it is found that:
[tex](h \circ g)(2) = 13[/tex]
The composition of functions h(x) and g(x) is given by:
[tex](h \circ g)(x) = h(g(x))[/tex]
In this problem, the functions are:
[tex]h(x) = 2x - 1[/tex]
[tex]g(x) = 3x + 1[/tex]
Then:
[tex]h(g(x)) = h(3x + 1) = 2(3x + 1) - 1 = 6x + 2 - 1 = 6x + 1[/tex]
At x = 2:
[tex](h \circ g)(2) = 6(2) + 1 = 13[/tex]
