Answer:
b= 5
c = 10, x=7 hypotenuse = 7
Step-by-step explanation:
A 30-60-90 triangle has the ratios of x-x-2x so if x=5, then 5-5 - 10
for a 45-45-90, if one leg is 7, so is the other x so hypotenuse is 7
Answer:
isnt it b
Step-by-step explanation:
Answer:
t = 13
Step-by-step explanation:
3 months ------ 4500
6 months ------ x
3/6 = 4500/x
cross multiplation:
3x =27000
x = 9000,or we should have just doubled the wages, since the time doubled
3 months ------ 4500
5 months ------ y
3/5 = 4500/y
3y = 22500
y = 7500
3 months ------- 4500
t months -------- 19500
3/t = 4500/19500 = 3/13
3t = 39
t = 13
Answer:
27
Step-by-step explanation:
Given the ratio 3 : 9
and 9 : ?
note that 3 × 3 = 9, thus 9 × 3 = 27
3 : 9 = 9 : 27
Complete the equation of variation where y varies inversely as x and y = 0.125
when x=8
