Answers:
A. -11÷4
B. 11 ÷ (-4)
D. -11/4
E. 11/-4
Reasoning:
In a fraction, it doesnt matter where the negative is. Since we have a single negative sign, our answer must also have a single negative. (2 negative signs will cancel each other out.)
Answer:
Volume of cylinder = 250πm³
Step-by-step explanation:
Given:
Height h = 10 m
Radius r = 5 m
Find:
Volume
Computation:
Volume of cylinder = πr²h
Volume of cylinder = π(5)²(10)
Volume of cylinder = 250πm³
To work out how many miles the distance from the airport to the beach, we can use 1km ≈ 0.62 miles
To get from 20km from 1km, we multiply by 20
If we do the same to 0.62
0.62 x 20 = 12.4 miles
Next step is to add this on to the 500 miles they travelled by plane
500 + 12.4 = 512.4 miles
0.51 is the answer since the nine converts the zero before it to a 1

Answer:
yes
Step-by-step explanation:
If GH║FE, then ∆DEF ~ ∆DHG.
In similar triangles, corresponding sides have the same ratios.
The ratios of corresponding sides are ...
DG/DF = DH/DE
DG/(DG + GF) = 18/(18+36)
(1/2GF)/((1/2GF +GF) = 1/3
(1/2)/(3/2) = 1/3
1/3 = 1/3
Corresponding sides are proportional. Angle D is congruent to itself, so ∆DEF ~ ∆DHG by the SAS similarity postulate. Angles DGH and DFE are therefore congruent and GH║FE.
