A cylindrical soup can has a radius of 1.8 in. and is 6.7 in. tall. Find the volume of the can.
Volume = base area x tall
base area = π x (1.8in)²
base area = 10.179 in²
Volume = 10.179 in² x 6.7 in
Volume = 68.198 in³
Answerthe volume is 68.198 in³
When you flip a baised coin the probability of getting tail is 0.75 How many times would you expect to get tails uf you flip the coin 320 times?
Answer: 60
How?: Well, we know that we have a 0.75 chance for tails. And on a coin, there is heads and tails. So, we multiply 0.75 (tails) by 320 and then divide that by 4. We do this because there is a 0.75 and 1 = 1.00. 1.00 - 0.75 = 0.25. 0.25 = 60

i’m stuck on these questions
Answer:
In my opinion both of the lines are tangent.
Step-by-step explanation:
Because a tangent to a circle is a straight line which touches the circle at only one point. This point is called the point of tangency. The tangent to a circle is perpendicular to the radius at the point of tangency.
The cost of a 9 litter of petrol is $ 378. How much is 15 litres of petrol cost ?
Answer:
$630
Step-by-step explanation:
cost of each litter of petrol 378/9=42
cost of 15 liters of petrol 42x15=630
15 litters of petrol cost $630
Answer: $630
Step-by-step explanation:
[tex]9l[/tex] = $[tex]378[/tex]
[tex]\frac{378}{9}[/tex] to find [tex]xl[/tex] = $42
This means [tex]1l[/tex] = $42[tex]42[/tex] × [tex]15[/tex] = $[tex]630[/tex]How many ounces of yogurt can you get

Is 4/5 greater or less than 45/100 how do you know
Answer:
4/5 is grater than 45/100
Step-by-step explanation:
Why?
because in percentage you make the bottom # a 100 one of them already has that and when it has 100 on the bottom it tells you that the top # is the percentage so 45/100 is 45%
now to make 4/5 a percentage what times 5 = 100?
20 does
so you times the top and bottom by 20
4*20= 80
now your fraction is 80/100 (top # tells you the %)
it's 80%
80% is grater than 45%
Answer:
4/5 is greater than 45/100.
Step-by-step explanation:
In order to figure it out, you need to make both fractions have common denominators. In order to do that, you figure out this:
5 times what equals 100? It's 20.
With fractions in this situation, whatever you do to the top, you have to do to the bottom. So, you multiply 4 times 20, which is 80.
In the end, you would end up with these two fractions:
80/100 and 45/100.
Obviously, 80/100 is greater than 45/100. In the beginning, 80/100 was originally 4/5. Therefore, 4/5 is greater than 45/100.

272 square inches
Step-by-step explanation:
Given
[tex]l = 8[/tex] --- length
[tex]w = 2[/tex] --- width
[tex]h = 12[/tex] ---- height
Required
Determine the total surface area (SA)
This is calculated using:

Myrna wants to know how many pairs of jeans middle school students own. She did not have time to ask all 257 middle school students, so she surveyed a random sample of 25 students. The results below display the number of pairs of jeans each surveyed student owns.
3, 4, 2, 1, 3, 1, 2, 4, 2, 3, 1, 2, 4, 2, 3, 2, 2, 6, 1, 1, 2, 4, 1, 1, 2
The mean of her data is 2.36 pairs of jeans. From the given data and the calculated mean, which inference could Myrna make?
A. All middle school students own jeans.
B. The average middle school student owns around two pairs of jeans.
C. Most seventh-grade students prefer cargo pants to jeans.
D. An average middle school student owns three or more jeans.

Answer:
1st pic:
x = 60
y = 50
2nd pic:
y = 8
∠W = 28
∠Y = 128 degrees
∠X = 24
Step-by-step explanation:
first pic:
to find x, subtract 120 from 180 ⇒ 180 - 120 = 60
to find y, add 60 & 70 & subtract the sum from 180 ⇒ 180 - (60 + 70) = 50
2nd pic:
to find ∠Y, subtract 52 from 180:
180 - 52 = 128
to find y, use the following equation:
3y + 4y - 4 + 128 = 180
combine like terms:
7y + 124 = 180
subtract 124 from each side:
7y + 124 - 124 = 180 - 124
7y = 56
divide 7 on both sides:
[tex]\frac{7y}{7} = \frac{56}{7}[/tex]
y = 8
now we can find angles W and X
∠W = 4y - 4
we know that y = 8 so just substitute 8 for y
∠W = 4 x 8 - 4
∠W = 28
∠X = 3y
likewise, subtitute 8 for y
∠X = 3 x 8
∠W = 24
to check, add all angles and if they add up to 180, then its right:
24 + 28 + 128 = 180
180 = 180
Step-by-step explanation:
here's your solution
=> for first figure , (x + 120° ) = 180° [ linear pair]
=> x = 180° - 120°
=> x = 60°
=> now , we know sum of all angles of traingle = 180°
= >so, 60° + 70° + y = 180°
=> y= 180° - 130°
=> y = 50
now in figure second
=> 4y - 4 + 3y = 52° [ exterior angle equal to sum of two opposite interior
=> 7y - 4 = 52°
=> 7y = 52° + 4°
=> 7y = 56°
=> y = 56°/7
=> 8°
hope it helps
