Answer:
a) BE = 5; DE = 6; EF = 4
b) ∠EFC ≅ ∠DA.F ≅ ∠BDE or <em>b = e = f = i</em>
Step-by-step explanation:
Each short segment is the same length as the marked one it is parallel to.
E is the midpoint of BC, so BE = EC = 5.
ADEF is a parallelogram, so DE = A.F = 6.
D is the midpoint of AB, so AD = DB = 4. ADEF is a parallelogram, so ...
EF = AD = 4
__
As we have noted, AB║EF and DE║A.F, so corresponding angles and alternate interior angles are congruent. <em>b = e = f = i</em>
21 states
so there are 48 states in the continental US and 7+9=16 which is a third of 48, so you have to multiply the numbers by 3
Hello from MrBillDoesMath!
Answer: 1/3 (or 33 1/3 %) and 42 teachers
Discussion:
Part 1. If 16 out of 24 students made at least 80%, then 24 - 16 or 8 students made less than 80%.
Students who scored less than 80% / total number of students =
8/24 = 1/3
Part 2.
3 teachers for every 57 students so
3/57 = t/798 where t is the number of teachers
Multiply both sides by 798:
3/57 * 798 = t =>
3/57 * (14 * 57) = t as 798 = 14 * 57 so cancelling the 57's.
3* 14 =t
or t = 42
Thank you,
MrB
Answer:
7,460
Step-by-step explanation:
Whole numbers are counting numbers like 0, 1, 2, 3, . . .. Whole numbers are positive integers including 0
When rounding a number to the nearest whole number, firstly check the first digit after the decimal point. If the first digit is less than 5 we don't round up, but if the first digit is 5 or greater we round up.
Given the number 7,459.82
We check, the first digit after the decimal point, since this digit is greater than 5 (i.e. 8) we round u to get 7,460
