Answer:
A. A cylinder with diameter 8 units
Step-by-step explanation:
∵ The <u>line</u> m is the <em>central axis</em>
So the radius is 4 units. ∴ Diameter is 8 units.
∵ The picture is a <em>rectangle</em>.
[ The <em>rectangle rotates</em> are its side to form a <em>cylinder</em> ]
So a cylinder with diameter 8 units.
The answer is A.
Answer:
Your answer is:
1) 6 ( 5 + 8 ) = 78
2) 5 ( 10 + 3 ) = 65
3) 9 ( 2 + 4 ) = 54
4) 7 ( 3 + 6 ) = 63
Step-by-step explanation:
Hope this helped : )
You keep the same sign. So:-
4 + 4 = 8 and
--4 + -4 = -8
Answer:
67.5°, 107.5°
Step-by-step explanation:
For supplementary angles, their sum equals 180°.
Let x be the first angle and y be the second angle, then
x + y = 180°.
It is given that x = y + 45°.
So x + y = 180°
substituting x into the equation, we have
y + 45° + y = 180°
simplifying, we have
2y + 45° = 180°
collecting like terms, we have
2y = 180° - 45°
2y = 135°
dividing through by 2, we have
y = 135°/2
y = 67.5°
Since y = 67.5°
then x = y + 45°
x = 67.5° + 45°
x = 107.5°
Answer: 25 + 3n
Step-by-step explanation:
Hi, the answer is lacking the last part:
<em>Write an expression for the amount of money he makes this week.
</em>
So, to answer this we have to write an expression:
The fixed amount that he earns per week (25) plus the product of the amount he earns per subscription (3) and the number of subscriptions sold (n) , must be equal to his weekly earnings.
Mathematically speaking:
25 + 3n
