6 is the answer cuz 6 times 4 is 24
Answer:
60
Step-by-step explanation:
The corresponding angles of the triangles are given, y + 10 and 2y - 40. You need to first find the value of the variable (in this case, y), and to do this, you need to set them equal to one another:
y + 10 = 2y - 40
<u>Subtract y from both sides:</u>
<u />
y + 10 = 2y - 40
-y -y
____________
10 = y - 40
<u>Add 40 to both sides:</u>
<u />
10 = y - 40
+40 +40
________
50 = y
Now that we have the value of y, you need to plug the value into one of the expressions (either one will come out with the same answer):
y + 10
50 + 10 = 60
<em><u>OR</u></em>
<u />
2y - 40
2(50) - 40
100 - 40 = 60
<u />
Answer:
I dont know exactly but i think its C
Step-by-step explanation:
bc its the interest
Answer:
Positive 8 3/4
Step-by-step explanation:
My way:
-1 2/3 times -5 1/4
- 1 2/3 simplifies to -5/3
-5 1/4 simplifies to -21/4
-5/3 times -21/4 is 35/4
Simplify that which is 8 3/4
(negative times negative = positive)
Answer:
r= 0.08 ft
Step-by-step explanation:
C= $500 per cubic foot
S=$20 per square foot of surface area
We know that
Profit = Selling price - Manufacturing price
P = S - C
Lets take r is the radius of sphere
Surface area ,A= 4πrr²
Volume ,V= 4πr³/3
P = S - C
P = 20 x 4πr² - 500 x 4πr³/3
For maximize the profit
dP/dr = 0
P = 20 x 4πr² - 500 x 4πr³/3
dP/dr = 160 πr - 2000 πr²
160 πr - 2000 πr² = 0
160 - 2000 r = 0
r= 0.08 ft
d²P/dr² = - 4000 πr
d²P/dr² is negative at all value of r that is why at r=0.08 ft ,it is maximum.
