Answer:
16:7
Step-by-step explanation:
192 inches is 16ft
The equation that works for this is
y=1/7x + 0! It is parallel and goes through (0,0)
Hope this helps :)
Answer:
30 hrs
Step-by-step explanation:
In 1 hour, J completes 1/55 of job
In that time, D completes 1/66 of job
J + D together complete 1/55 + 1/66 of the job in 1 hour
1/55 + 1/66 = 1/30
Together, it takes them 30 hours to build the wall.
Answer:
88 degree
Step-by-step explanation:
We assume the measure of MN is x degree.
As the measure of LP is 30 degree more than that of MN, so that the measure of LP is: x + 30 degree
In the circle, as 4 points M,N,P,L are on the circle, we have:
+) ∡MPN = 1/2 * (measure of ∡MPQMN) = x/2 = ∡MPQ
+) ∡LMP =1/2 * (measure of LP) = (x+30)/2 = ∡QMP
We have ∡NQM and ∡MQP are complementary angles, so that:
∡MQP + ∡NQM = 180
=> ∡MQP = 180 - ∡NQM = 180 -103 = 77
In the triangle QMP, total measure of 3 internal angles are 180 degree, so that:
∡MQP + ∡QMP + ∡MPQ = 180
=> 77 + (x + 30)/2 + x/2 = 180
=> 77 + x/2 + 15 + x/2 = 180
=> x = 180 -77-15= 88
So that the measure of MN is 88 degree
