PQRS is an isosceles trapezoid and m < Q=127
so m<Q = m<P =127
answer
127
solve for "l" to find its length
X= your age
400-2x=244
-2x=-156
x=78
you are 78 years old
Answer:
There were 20 questions on the quiz
Step-by-step explanation:
In this question, we are concerned with knowing the number of questions on a quiz, given that Deana had a certain percentage after scoring an amount of marks.
We proceed as follows;
Let the number of questions on the quiz be X.
Now, she got 85% by making 3 incorrect choices. This means the percentage of questions she got incorrectly would be 100-85 = 15%
what we are saying is that it is just 15% of her questions that were wrong.
This mathematically;
15% of x = 3
15/100 * x = 3
15x = 3 * 100
15x = 300
x = 300/15
x = 20
4x+24=84 4x=60 x=15 length =27 width = 15
