Answer:
Rounded to the nearest integer, the test had 18 problems in all.
Step-by-step explanation:
Given that a student missed 10 problems on an English test and received a grade of 44%, if all the problems were of equal value, to determine how many problems were on the test the following calculation must be performed:
100 - 44 = 56
56 = 10
100 = X
100 x 10/56 = X
1,000 / 56 = X
17.85 = X
Thus, rounded to the nearest integer, the test had 18 problems in all.
Answer:
4.9 units
Step-by-step explanation:
Distance between 2 points= sqrt [(x-x)^2 + (y-y)^2
A= -4,2) and B= (1,4)
d = sqrt[(-4-1)^2 + (2-4)^2]
= sqrt (25+4)
= sqrt29
= 4.9 units
PR=18mm
AB=7mm
All lengths of triangle PRQ are twice the lengths of ACB
The answer is here written
