45 + 32 + 37 = 114
114÷3 = 38
4 total quizzes,
for a 40 average on 4 quizzes she needs 40*4 = 160 total points
for 3 quizzes she has 45 +32 +37 = 114 points
160-114 = 46, she needs at least a 46 on the 4th quiz
Area of a rectangular lawn = l×b
255=15×x
Hence the breadth is 17 m
Hence perimeter =2(l+b)=2(15+17)=64
h. y / x^2
j. 0.00001
k. 0.000005
I. 0.025
m. 8 times 10^-3
n. 1.25 times 10^-4
o. 5 times 10^-7
p. 0.000000001
I only did the ones I see, hope it helps.
Answer:
1 7/5
Step-by-step explanation:
we should first simplify the fraction part of each option
7/5 = 1 2.5 add this to 1 and you get 2 2/5
this happens to be the answer but in the future go through each option
80 degrees. 145 = (4x+5) + (6x-10) = 10x-5... so 10x = 150, x = 15. LMN = 6x-10 = 6(15) - 10 = 80.
