Step-by-step explanation:
If K is the midpoint of JL, then JK and KL will be congruent to each other because a midpoint divides a line into two congruent segments.
JK ≅ KL
Now, let's add in the expressions.
2x + 4 = 4x - 8
-2x + 4 = -8
-2x = -12
x = 6
So, the value of x is equal to 6. Since JK is congruent to KL, then we can plug in x for one of the equations and multiply that answer by 2 so we can find the measurement of JL.
JK = 2(6) + 4
JK = 12 + 4
JK = 16
16 * 2 = 32
So, the measurement of JL is equal to 32.

Answer:
21
Step-by-step explanation:
We need to utilise one important angle in order to answer this question which is
→ Angles in a triangle add up to 180°
Using this information we can set up an equation to find the value of x
⇒ Form equation using the important angle fact
→ x - 4 + 3x + 100 = 180
⇒ Simplify the 'x' and the numerical terms
→ 4x + 96 = 180
⇒ Minus 96 from both sides to isolate 4x
→ 4x = 84
⇒ Divide both sides by 4 to isolate x
→ x = 21
The value of x is 21
It takes 24 electricians 36 days to wire a new housing subdivision. How many days would 32 electricians take to do the same job?
Answer: 27 days
Step-by-step explanation:
Hi, to answer this question we have to apply inverse relation:
Since it takes 24 electricians 36 days to wire a new housing subdivision, the relation is:
24 (36)
For 32 electricians:
24(36) = 32 (x)
Solving for x (days)
864 =32x
864/32 =x
x= 27 days

Eden combines 2/8 cups blueberries 5/8 cup raspberry and 3/8 cup strawberries in her mixed fruit topping she puts 1/4 cups of that mixed fruit topping on each fruit topping on each bowl on how many oatmeal bowls can she put fruit topping
Answer:
5 bowls
Step-by-step explanation:
[tex]\frac{2}{8}[/tex] + [tex]\frac{5}{8}[/tex] + [tex]\frac{3}{8}[/tex] = [tex]\frac{10}{8}[/tex]
Change denominator to 4 by dividing both numerator and denominator by 2.
[tex]\frac{10/2}{8/2}[/tex] = [tex]\frac{5}{4}[/tex]
Each serving is [tex]\frac{1}{4}[/tex] cups, and the mix is [tex]\frac{5}{4}[/tex] cups, so Eden can have 5 bowls of oatmeal.

The students in art class are designing a stained-glass window to hang in the school entryway. The window will be 3 feet tall and 4 feet wide. Here is their design → They have raised $100 for the project. The colored glass costs $5 per square foot and the clear glass costs $2 per square foot. The material they need to join the pieces of glass together costs 10 cents per foot and the frame around the window costs $4 per foot. Do they have enough money to cover the cost of making the window?
Answer:
They dont have enough money
Step-by-step explanation:
Colored Glass =
$5/ 1 sq = 60 / 12 sq
Clear Glass =
2/1 = 24 / 12
Materials =
.1/ 1= 1.2 / 12
Frame=
$4 / 1 ft = 28 / 12
ADD THE TOTALS
60+24+1.2+28 = 113.2
Students do not have enough money to cover the cost of making the window.
Given that, the window will be 3 feet tall and 4 feet wide.
What is the area of a rectangle?The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.
Area of a rectangle =3×4
= 12 square feet
Now, the total cost = 5+2+0.10+4
= $11.1
The cost per 12 square feet area
= 12×11.1
= $133.2
Therefore, students do not have enough money to cover the cost of making the window.

Sam rides his bicycle for 1.6 hours.
Here is the solution:
Time = Distance / Speed
Time = 11.2 km / 7 km/hour
Time = 11200 m / 7000 m/hour
Time = 1.6 hours

Bhavik bought 3 liters of milk and 5 loaves of bread for a total of $11. A month later, he bought 4 liters of milk
and 4 loaves of bread at the same prices, for a total of $10.
How much does a liter of milk cost, and how much does a loaf of bread cost?
Aliter of milk costs $
and a loaf of bread costs $
Answer:
Step-by-step explanation:
A liter of milk cost $.75
A loaf of bread cost $1.75
Answer:
Step-by-step explanation:
Cost of milk = $ m
Cost of bread = $ b
3m + 5b = 11 ------------------(I)
4m + 4b = 10 ----------------(II)
Multiply equation (I) by 4 and multiply equation (II) by (-3). Thus when you add, m will be eliminated and we can find the value of b
(I)*4 12m + 20b = 44
(II)*(-3) -12m - 12b = -30 {Now add & m will be eliminated}
8b = 14
b = 14/8
b = $ 1.75
Cost of a loaf of bread = $ 1.75
Plugin the value of b in equation (I)
3m + 5*1.75 = 11
3m + 8.75 = 11
3m = 11 - 8.75
3m = 2.25
m = 2.25/3
m = $ 0.75
Cost of one liter of milk = $ 0.75

A jar contained 6 red marbles, 10 green marbles, and 8 blue marbles. A marble was selected at random, the color was recorded, and the marble was placed back in the jar. The table shows the results after 60 trials.
What was the relative frequency of selecting a red marble?
Enter your answer in the box to the nearest percent.
Answer:
Step-by-step explanation:
22 percent
22% is the approximate percentage of the relative frequency.
What is relative frequency?Relative frequency is the ratio between the absolute frequency (how many repetitions have a specific outcome) and the total outcomes. Also, this type of frequency is used to show the representation that some data have over the whole distribution.
So, in this case, we need to just divide 13, which belongs to red marble's results, to 60 which is the total outcomes, as it's presented:
P = Red marbles / total marbles = 13/60 = 0.22
Normally, relative frequency is shown as a percentage multiplying this result by 100.
Therefore, 22% is the approximate percentage of the relative frequency, which means that 22% is the representation of red marbles outcomes of the whole distribution, or we can say it as a probability: there's 22% of chances when someone extract a marble, it will be red.
Hence 22% is the approximate percentage of the relative frequency.

Find the volume of the prism.
Answer:
C = 210cm^3
Step-by-step explanation:
We can get an estamate when we use the equation L x H x W = x/2
This shows 8 x 8 x 7, then divide by 2 = 224cm^3
The reason it is slightly less could be the facts the teachers want you to remember this one.
For right side prism the equation is (1/2)b x h x H
which means;
The volume of a triangular prism can be found by multiplying the base times the height. Both of the pictures of the Triangular prisms below illustrate the same formula. The formula, in general, is the area of the base (the red triangle in the picture on the right) times the height,h.
We use the side and base that surrounds the right side as (1/2)base and as side to find area then use the H as the height being the 7.
Answer:
D. 168 units^3
Step-by-step explanation:
volume of prism = (area of base) * (height of prism)
The height of the prism is the distance between the triangular bases, and is 7 units.
The base of the prism is a triangle with base 6 units and height 8 units.
area of triangle = base * height / 2 = 6 * 8/2 = 24 square units
volume of prism = (area of base) * (height of prism)
volume of prism = (24 square units) * (7 units)
volume of prism = 168 cubic units

What is Coordinate Geometry?A coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine the position of the points or other geometric elements on a manifold such as Euclidean space.
Lines of symmetry are mixed up with rotational symmetry.
A line of symmetry divides the shape equally into two symmetrical pieces.
A rotational symmetry is the number of times a shape fits into itself when rotated around its centre.
Rectangle has both line and rotational symmetry
The Z has line symmetry
The trapezoid has none of the symmetry.

If two angles are complementary and one measures 36°, what is the measure of the other angle?
Answer: 54°
Step-by-step explanation: If two angles are complementary, then the sum of their measures is 90 degrees.
If the measure of an angle is 36°, then
the measure of its complement is 54°.
We can find the measure of its complement by taking 90 minus the measure of the original angle which in this case is 90 - 36 or 54°.
