Hi there!
You are partially correct on the π symbol, but there's more!
The formula for finding the area of a circle is:
A = π r².
A stands for area, π stands for pi, and r stands for radius. The ² is there because the radius is half as big as the diameter of a circle.
Hope this helps! :D
And remember, you can message me whenever you need to on anything you may need help with!
b.Find the amount of milk in 3 mugs
Answer:
a) 1/9 quarts
b) 1/3 quarts
Step-by-step explanation:
Gordon pours 4/9 quarts of milk from a pitcher equally into 4 mugs.
a. Find the amount of milk in each mug.
To solve the first part of this question, we can simply use the idea of proportion;
Let x be the amount of milk in 1 mug
4/9 quarts = 4 mugs
x = 1 mugs
We will cross multiply
4x = 4/9
To get the value of x, we will divide both-side of the equation by 4
4x/ 4 = 4/9 ÷ 4
(on the left hand- side of the equation, 4 will divide 4 leaving us with x)
x = 4/9 ÷ 4
( This ÷4 can be change to become × 1/4)
x = 4/9 × 1/4
(The 4 at the numerator will cancel out the 4 at the denominator leaving us with 1/9)
x = 1/9
Therefore the amount of milk in each mug is 1/9 quart
b.Find the amount of milk in 3 mugs
For this second part of the question, we can also use proportion to solve;
Let x be the amount of milk in 3 mugs
4/9 quarts = 4 mugs
x = 3 mugs
Cross multiply
4x = 3 × 4/9
(At the right-hand side of this equation 3 can divide 9 which will give us 3 )
4x = 1 × 4 /3
4x = 4/3
We can now divide both-side of the equation by 4 to get the value of x
4x/4 = 4/3 ÷ 4
(On the left hand side of the equation, 4 will cancel out 4 leaving us with just x and on the right-hand side of the equation ÷ 4 can be changed to ×1/4)
x = 4/3 × 1/4
(4 will cancel 4 leaving us with 1/3)
x = 1/3
Therefore the amount of milk in 3 mugs is 1/3 quarts
Answer:
x = 22
y = 32
Step-by-step explanation:
The sum of interior angles in a rectangle is 360° so
100° + 5y + 4x + 2x = 360 add like terms
6x + 4y = 260°
Now, we know that the measure of an inscribed angle in a circle is equal to the half of the arc it sees
so if the arc that 100° sees is equal to 200 then the arc 5y sees would be 160 (because perimeter of a circle is 360°)
if 5y = 160 then y = 32
We said 6x + 4y = 260° since we know what y is equal to now we can replace the value
6x + 4×32 = 260
6x + 128 = 260
6x = 132
x = 22
I think there must be a mistake in answering options but this is how we solve this kind of problems.
Answer:
To me, none of the answers seem correct.
Step-by-step explanation:
x = 30, y = 20 is 100 + 60 + 120 + 100 which is 380 total, so incorrect
x = 2, y = 2 is 10 + 10 + 8 + 100 which is 128 total, so incorrect
x = 60, y = 25 is 125 + 120 + 240 + 100 which is too great, so incorrect
x = 60, y = 52 is too great, so incorrect
Plz let me know what I did wrong if anyone gets the answer...
The 0.15 is a bigger number than 0.125 that is 0.15 > 0.125.
Inequality is defined as an equation that does not contain an equal sign.
The numbers are given below.
0.125 and 0.15
Then the 0.15 is a bigger number than 0.125 that is 0.15 > 0.125.
