16.45 - 6.4 = 10.05kg of flour to make 15 batches of scones
1 batch = 10.05/15
= 0.67kg of flour.
Answer:
- Total surface area of cylinderal can is 150.8 cm²
<u>Step-by-step </u><u>explanation</u><u>:</u><u> </u>
Given that a cylinderal can has base with a diameter of 6 cm and its height measures 5 cm.
So,
Radius = Diameter/2 = 6/2 = 3 cm
We know that,
- TSA of cylinder = 2πr(h + r)
Substituting required values:
➝ TSA = 2 × 22/7 × 3(5 + 3)
➝ TSA = 44/ 7 × 3 × 8
➝ TSA = 1056/7
➝ TSA = 150.8 cm²
Hence,
- <u>Total </u><u>surface </u><u>area </u><u>of </u><u>cylinderal</u><u> </u><u>can </u><u>is </u><u>1</u><u>5</u><u>0</u><u>.</u><u>8</u><u> </u><u>cm²</u>
Answer:
n = 10
Step-by-step explanation:
move all terms to the left:
-2-(-(n-8))=0
calculate terms in parentheses: -(-(n-8)), so:
-(n-8)
get rid of parentheses
-n+8
add all the numbers together, and all the variables
-1n+8
go back to the equation:
-(-1n+8)
get rid of parentheses
1n-8-2=0
add all the numbers together, and all the variables
n-10=0
move all terms containing n to the left, all other terms to the right
n=10
According to my calculations the answer is 69
2 acute and 2 obtuse and 0 right angles
