Answer:
x = 35, y = 18
Step-by-step explanation:
Since both triangles are similar, their sides must be proportional with means all of them have a common ratio.
If NM = 16, and KJ = 40. 40/16 is the ratio from ∆NML to ∆JKL. The reciprocal(numerator and denominator flip, the product of a number and it's reciprocal is 1) of this is true from ∆JKL to ∆NML.
Now to find the missing sides you multiply a side by the common ratio to find it's corresponding side length.
Dividing by a number is the same as multiplying by the reciprocal of that number.
40/16 can be reduced to 5/2 or 2 ½ as a mixed fraction.
16/40 can be reduced to 2/5 or 0.4 as a decimal.
Since the scale of ∆JKL is greater than ∆NML, you multiply by 5/2 to get the corresponding side of ∆JKL from ∆NML.
Since the scale of ∆NML is less than ∆JKL, you multiply by 2/5 to get the corresponding side of ∆NNL from ∆JKL.
Therefore x = 14 × 5/2 = 70/2 = 35.
y = 45 × 2/5 = 90/5 = 18.

consider a rectangular prism with length 4 and width and height d
Find an expression for the volume of the prisms in terms of d.
2. compute the volume of the prism when d=1, when d=2, and when d=1/2
Answers
Answer:
Step-by-step explanation:
The expression for the volume of the prisms in terms of d is 4d².
What is a volume?Volume is the amount of space occupied by a three dimensional shape or object. For a rectangular prism:
Volume = length * width * height
From the diagram, length = 4, width = d, height = d. Hence:
Volume = 4 * d * d = 4d²
When d = 1: Volume = 4(1)² = 4
When d = 2: Volume = 4(2)² = 16
When d = 1/2: Volume = 4(1/2)² = 1
The expression for the volume of the prisms in terms of d is 4d².

A basketball court is a rectangle that is 94 feet long. The area is 4700 square feet. What is the width of a basketball court?
A. 25 feet
B. 41 feet
C. 50 feet
D. 100 feet
Answers
Answer: C: 50 feet
Step-by-step explanation: The area of the basketball is 4700 square feet. We know that one side of the court is 94 feet long. To find the area for a rectangle, the formula would be Area=base times height. The "height" of this rectangle is 94 feet long. Now we need to find the base.
If you divide 4700 by 94, you will end up with 50 feet. To check, you multiply 50 by 94 and should end up with 4700. 50 feet is your base length.

The area of the large triangle is 36*24/2
minus the small triangle which is 21*14/2
so 432-147 = 285
So first get the length of the bottom of the triangle, so that would be 36in. Minus 21in. Which will give us the length of the bottom of the shaded region.
36-21= 15 in.
This next step isn’t necessary, but it makes solving for the area so much easier. Make the shaded region into two different shapes. So in this case, a square and then a right triangle.
So take the height on both sides on the shaded region, which would be..
24 - 14 = 10in.
Now, multiply the length by the height to solve for the area of the square and triangle.
Triangle area: 15(10)= 150 sq. in.
Square area: 15(14)= 210
Now add them together and then you get your answer.
210 + 150 = 360 sq. in.
The area of the shaded region is 360 sq. in.

A pair of jeans is normally priced at $56, but is currently marked down for with a 35% discount. What would replace the B in the proportion? A/B=P/100%
Answers
Answer:
$36.4
Step-by-step explanation:
Given
Cost of Jean = $56
Percent markdown = 35%
Discount = 35% of $56
Discount = 0.35 * 56
Discount = $19.6
New price = $56 - (35% of $56)
New price = $56 - 19.6
New price = $36.4
hence the price that will replace B is $36.4

A DVD rental service wants to pay close attention to what movies their customers like the most. Which measure of central tendency will give them the best estimate? Explain.
Answers
Answer:
Mode.
Because it is used to determine the most frequently occurring item which in this case is movie.
Step-by-step explanation:
The 3 measure of central tendencies are namely;
Mean, median mode.
- Mean is defined as the average of a set of data.
- Median is the middle term of a set of data that splits that set of data into 2.
- Mode is the term that occurs most frequently in a set of data.
In this question, we want to find the movies most frequently watched.
Thus, from the definitions above earlier, it is clear that the only way to know this is using the mode.
