Answer:
78.54 (rounded to 2 d.p)
Step-by-step explanation:
The formula for the volume of cylinder is πr(squared)h
Radius is half of the diameter so 5/2 = 2.5
The height is 4
Therefore,
π x 2.5 x 4 = 78.53982

Is the relationship between the cost and quantity of apples proportional? Explain.
Answer:
No.
Here's the break why it is not proportional...
[tex]3*4 = 12\\6*4=24\\9*4=36\\8*6=48\\10*6=60[/tex]
The proportion breaks near the end because the multipliers no longer match.
Answer:
It is not proportional
Step-by-step explanation:
12 apples=$3 60 apples=$10
/3 /3 But... /10 /10
4 apples=$1 6 apples=$1
The price went down so it's not proportional

Answer:

——— < 0
10
Step-by-step explanation:
Changes made to your input should not affect the solution:
(1): "3.3" was replaced by "(33/10)".
Rearrange the equation by subtracting what is to the right of the greater than a sign from both sides of the inequality :
3*(-1-2)-(-26-(33/10))<0
33
Simplify ——

33
-9 - (-26 - ——) < 0
10
Subtracting a fraction from a whole
Rewrite the whole as a fraction using 10 as the denominator :
-26 -26 • 10
-26 = ——— = ————————
1 10
Equivalent fraction: The fraction thus generated looks different but has the same value as the whole
the Common denominator: The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
-26 • 10 - (33) -293
——————————————— = ————

-293

Subtracting a fraction from a whole
Rewrite the whole as a fraction using 10 as the denominator :

The diagram shows a circle inside a rectangle....
Answer:
let [tex]x[/tex] = height of rectangle
Given:
height of rectangle = diameter of circlelength of rectangle = 3 × height of rectangleTherefore,
height of rectangle = [tex]x[/tex]diameter of circle = [tex]x[/tex]radius of circle = [tex]\dfrac{1}{2}x[/tex]length of rectangle = [tex]3x[/tex]Shaded area = area of rectangle - area of circle
Area of rectangle = length × height
= [tex]3x \times x[/tex]
= [tex]3x^2[/tex]
Area of circle = [tex]\pi r^2[/tex]
[tex]=\pi \left(\dfrac{1}{2}x\right)^2[/tex]
[tex]=\dfrac14\pi x^2[/tex]
[tex]\implies \textsf{shaded area}=3x^2-\dfrac14\pi x^2[/tex]
If the radius = 2 cm, then the diameter ([tex]x[/tex]) = 4 cm
Substituting [tex]x = 4[/tex] into the equation:
[tex]\implies \textsf{shaded area}=3(4)^2-\dfrac14\pi (4)^2[/tex]
[tex]\implies \textsf{shaded area}=48-4\pi[/tex]
[tex]\implies \textsf{shaded area}=4(12-\pi) \textsf{ cm}^2[/tex]

Step-by-step explanation:
x^2-10=0 solve for all real values of x
this is very hard lol pls help
so x^2-10=0
we add 10 to both sides of the equation x^2 = 10
then take the square root of both sides of the equation to eliminate the exponent on the left side x = ± √10
The complete solution is the result of both the positive and negative portions of the solution. x = √10 ,−√10
the result can be shown in multiple forms
Exact Form :x=√10,−√10x=10,-10
Decimal Form: x=3.16227766…,−3.16227766
