An oatmeal container has a diameter of 20 cm and can hold 1570 cm3 of oatmeal. What is the height of the container of oatmeal
Answer:
5 cm approx
Step-by-step explanation:
Given data
Diameter= 20cm
radius= 10cm
Volume= 1570cm^3
We know that the expression for the volume of the container/cylinder is
V= πr^2h
1570= 3.142*10^2*h
1570=3.142*100*h
1570=314.2h
h= 1570/314.2
h=4.99 cm
Hence the height is 5 cm approx

It's one or the other, so the two on the graph won't connect, and each of them are greater/less than, NOT "or equal to" so both the circles would be closed. When thinking of these, forget about the x and just read greater than 5. On a graph the greater numbers are to the right, so the arrow would be pointing that way

Answer:
x must be 3
Step-by-step explanation:
First, combine like terms. (-5/3)x - (1/3)x = - 3 - 3 = -6
Then (-6/3)x = -6, or 2x = 14. Then x must be 3.
Check: is (-6/3)(x) = -6 true for x = 3? Is 2x = 6 true for x = 3? YES

Given:
The figure of two parallel lines MP and QS.
A transversal line KL interests the two parallel lines.
[tex]m\angle KNM =146^\circ[/tex]
To find:
The [tex]m\angle KRQ[/tex].
Solution:
If a transversal line intersect the two parallel lines, then the corresponding angles are congruent and their measures are equal.
In the given figure [tex]\angle KRQ[/tex] and [tex]\angle KNM [/tex] corresponding angles. It means their measures are equal.
[tex]m\angle KRQ=m\angle KNM[/tex]
[tex]m\angle KRQ=146^\circ[/tex]
Therefore, [tex]m\angle KRQ=146^\circ[/tex].
What is the yintercept of the graph of the equation y = 2(4*)?
O A. (0,4)
B. (0,6)
C. (0,2)
D. (0,8)
Answer:
[tex]\boxed {\boxed {\sf C. \ (0,2)}}[/tex]
Step-by-step explanation:
The y-intercept of a graph occurs when the function cross the y or vertical axis. This is also where x is equal to 0.
Therefore, we can substitute 0 in for x and solve for y.
[tex]y= 2(4^x)[/tex]
[tex]y= 2(4^0)[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Solve the exponent. Any number raised to the power of 0 is equal to 1.
[tex]y= 2(1)[/tex]
Multiply.
[tex]y=2[/tex]
The y-intercept is 2. So, when x=0, y=2.
Coordinate points are written as (x, y). The y-intercept is (0,2).

Which type of interest can be described as interest that is earned on the principal amount only
Simple interest is the type of interest that is earned on the principal amount only.
What is Interest?Interest in simple terms is the extra amount that you have to pay if you borrow money or the extra money you get if you lend the money.
Simple interest is one of the type of interest.
Simple interest is defined as the interest obtained over the principal amount on a certain rate.
Suppose that, a certain transaction has an annual interest rate of 2% for a period of 10 years.
If the principal amount is P, then in simple interest, interest will be a fixed amount, that is, 2% of P, in the whole period.
In compound interest, the interest will be compounded each of the year or month or quarterly depending on the criterion.
Hence the type of interest described here is simple interest.

30m^2
60m^2
75m^2
63m^2
Answer:
63m^2
Step-by-step explanation:
Find the area of each base
2.5(10)= 25
1.5(10) = 15
2(10) = 20
Add them together
20 + 15 + 25 = 60
Now find the area of the triangles at each side
2(1.5)(1/2) = 1.5
Since there are two triangles, multiply the area by 2
1.5(2) = 3
Add the areas together
60 + 3 = 63
There's your answer
Answer:
63
Step-by-step explanation:
Atotal= Area of base + Area of lateral= 60+3 =63
2 Area of base = 2 ( 1/2 b h )
= 2( 1/2 2x 1.5 )
= 2( 1.5 )
= 3
3 Area of lateral = 3 bh = 2.5X10 +2X10 +1.5X10 = 25+20+15 = 60

Kirk drew a scale drawing of a petting zoo. The scale he used was 8 centimeters : 5 meters. The goat pen is 24 centimeters long in the drawing. How long is the actual pen?
The actual length of the pen is 15 meters
How to determine the actual length of the pen?The given parameters can be represented using the following ratio
Ratio = 8 centimeters : 5 meters
The scale length of the goat pen is given as
Scale length = 24 centimeters
So, we have
24 centimeters : Actual length = 8 centimeters : 5 meters
Rewrite as
24 : Actual length = 8 : 5 meters
Express as fraction
Actual length/24 = 5 meters/8
Multiply by 8
Actual length = 15 meters
Hence, the actual length of the pen is 15 meters
