Answer:
17x+4=123(alternate angle)
17x=123-4
17x=119
x=7
That equals <u>.0124031008</u>
Hey there Jefferymcdougl1,
Answer:
Brand X:
5 pounds = $43
1 pound = $43 / 5
= $8.60
Brand Y:
3 pounds = $27
1 pound = $27 / 3
= $9
Thus, Brand X is a better buy as Brand Y costs $0.40 more than Brand x
Hope this helps :D

Answer:
a. 754cm³ (3 s.f.)
b. 415cm² (3 s.f.)
Step-by-step explanation:
Formulas (for easier reference):
Volume of cone:
r²
Volume of hemisphere: 
r³
Surface area of cone without base:
rl
Surface area of hemisphere without base: 2
r²
We can just apply the formulas for the question:
Volume of toy = (
× 6² ×
) + (
×
6³)
= 96
+ 144
= 240
= 754cm³ (3 s.f.)
Surface area of toy = (
× 6 × 10) + (2 ×
× 6²)
= 60
+ 72
= 132
= 415cm² (3 s.f.)
