Answer:
7,912.8 inch³ of aluminum is needed to make 70 metal balls
Step-by-step explanation:
r = 3 inches and π = 3.14
single aluminum ball, 113.04 inch³ of aluminum
113.04 inch³ of aluminum is used for 1 ball, then we multiply 70 with this value to determine the aluminum needed for 70 such balls.

The sum of triangle angles = 180
180 = 90 + 2x +15 + x
75 = 3x
x = 25
Answer:
→x=25°
Step-by-step explanation:
→2x+15+x+90°=180°[Sum of a triangle is 180]
→3x+105°=180°
→3x=180°-105°
→x=75°/3
→x=25°

19. A bird flies at 12 miles/hour. How long does he take to fly 36 miles?
Answer:
He flew for 3 hours
Step-by-step explanation:
in this question we can use the formula :
[tex] \boxed{t = \frac{s}{v}} [/tex]
t is time
s is distance
v is Speed
_________________
We know that :
v = 12 miles/hour
s = 36 miles
So :
[tex] t = \frac{s}{v} = \frac{36}{12} [/tex]
[tex] \boxed{t = 3 \: hours}[/tex]

verify that the segment lengths form a triangle. is the triangle acute, right, or obtuse?
bc Answer: They form an obtuse triangle
Step-by-step explanation:
the length of one side must be greater than the difference and less than the sum of the lengths of the other two sides. In this case the third side must be greater than 3 and less than 31. 3(squareroot) 55 is 22.25 so it fits.

Round 112.3398 to the nearest hundredth. Enter your answer in the space
provided.
Answer:
112.34
Step-by-step explanation:
The 2nd digit after the decimal point is in the hundredths position.
• If the digit following is ≥ 5 then round up
• If the digit following is < 5 then leave digit as it is
here the digit following the 3 in the hundredths position is 9 so round up
112.3398 ≈ 112.34 ( to the nearest hundredth )

Bernard typically runs x km/hour. While he was sick, he only ran 41. 5 km/hour. What equation represents that the difference in his speeds is 13. 5 km/hour? x – 41. 5 = 13. 5 41. 5 x = 13. 5 13. 5 – x = 41. 5 13. 5 – 41. 5 = x.
Step-by-step explanation:
Typical speed of Bernard= x km/hr
Bernard's speed while sick= 41.5 km/hr
the difference in the speed=13.5 km/hr
the equation representing the difference will be:
x-41.5=13.5 km/hr

The simplified fraction is
[tex] \frac{2}{9} [/tex]
Step-by-step explanation:
Finding the HCF can help a great deal, so in this case the HCF between 16 and 72 is 8.
16/8 = 2
72/8= 9
Therefore the answer is
[tex] \frac{2}{9} [/tex]

Answer:
x²-25=?
Step-by-step explanation:
x² is known as a positive number.A positive number is any number more than 0
so we can there fore assume it's 4 so 4-25 no we can't so we divide
4÷25=0.16 it is a decimal.
Angle STV is a straight angle. The measure of WTV angle is 40. The measure of STW angle is x . What is the value of x?
Answer: 140
Step-by-step explanation:
We know that the angle measures must add to 180 deg, so:
40 + x = 180
x = 140.
A clothing store is having a sale on shirts and jeans. 4 shirts and 2 pairs of jeans cost $64. 3 shirts and 3 pairs of jeans cost $72. What is the cost of one shirt? What is the cost of one pair of jeans
Answer:
Shirt:8 ; jsans:16.
Step-by-step explanation:
Let’s shorten these terms: shirt=s ; jean=j.
3s+3j=72
4s+2j=64 => =2j=64-4s => j=(64-4s):2 => j=32-2s
3s+3j=72 => (instead of j we write 32-2s=> 3s+3*(32-2s)=3s+96-6s=72
=> -3s=72-96
-3s=-24
s=24:3
s=8.
=> j=32-2s => j= 32-16 => j=16.
Find the length y of the minute hand in 3 sf
Please help
Answer:
135 cm
Step-by-step explanation:
[tex] \cos(43) = \frac{75}{y} [/tex]
[tex]y = \frac{75}{ \cos(43) } [/tex]
[tex]y = 135[/tex]
Answer:
y ≈ 102 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos43° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{75}{y}[/tex] ( multiply both sides by y )
y × cos43° = 75 ( divide both sides by cos43° )
y = [tex]\frac{75}{cos43}[/tex] ≈ 102 cm ( to 3 sf )
