Victor can wash 2 cars in 8 minutes. At this rate, how long would it take for Victor to wash 20 cars?
Answer:
80 minutes or 1 hr 20 min
Step-by-step explanation:
This problem is proportional so if Victor washed 2 cars in 8 minutes, he can wash 1 car in 4 minutes. Therefore, 20 x 4 = 80 which is how long it would take him to wash 20 cars.

In the ordered pair below, which value represents the input to a function?
(4, 20)
4 units to the right + 20 units up
Step-by-step explanation:
can I get brainliest points
In the ordered pair (4, 20), the value 4 represents the input to a function.
Given data:
In the ordered pair (4, 20), the value 4 represents the input to a function. In a function, each input value is associated with a unique output value. The input value is also referred to as the "independent variable" or the "domain" of the function. It is the value for which we want to determine the corresponding output or "dependent variable."
In this case, the ordered pair (4, 20) indicates that when the input value is 4, the output value is 20. This means that there exists a function that, when given the input 4, produces the output 20. The input value, 4, is the specific value for which we are interested in understanding the behavior or relationship described by the function. The output value, 20, is the result of applying the function to the input value.
Hence, the value 4 in the ordered pair (4, 20) represents the input or independent variable of the function.

Answer:
Part A:
- angle ACB= 60° (ABC equilateral triangle.)
- Angle ECD=EDC= (180°-32°)/2= 148/2= 74° (sum of angles in a triangle is equal to 180, and triangle ECD is isosceles since it's given that CE=DE.
- x= 180°-(60°+74°)

Rachel is making nachos for a party. The recipe calls for 2/3 cup of cheese for each plate of nachos. How many full plates of nachos can Rachel make with 5 cups of cheese?
Answer:
7
Step-by-step explanation:
To find the answer you have to divide 5 by 2/3, if you use a calculator you'll get the answer 7.5, which isn't a whole so simply round it down to 7; as if you rounded it up to 8 you'd have way too many plates of nachos to actually be able to make that amount with how much cheese you have lol, hope this helped !!!

Answer:
40
Step-by-step explanation:
2/150 can be simplified to 1/75
this means that for every 75 products, 1 will be a defect.
divide 3000 by 75 and you will have your answer.
3000/75 =40.
it is likely there will be 40 defects
another method for this:
1/75 = ?/3000
75 x 40 = 3000 (this means that the denominators are equal. now we must multiply the top number by the same thing)
1x40 = 40.

What is a right-angle triangle?There are three angles in the triangle: two sharp angles and one 90-degree angle. The hypotenuse, perpendicular, and base are the names of the sides of a right-angled triangle.
We have,
Triangle DEF contains right angle E. If angle D measures 50° and its opposite side measures 7.6 units,
Applying the tan ratio in the right-angle triangle:
tan50 = EF/DE
tan50 = 7.6/DE
DE = 7.6/tan50
DE = 6.377
DE ≈ 6.38 units
Thus, the measure of the side length DE is 6.38 units.
