Answer:
314 cm³
Step-by-step explanation:
Given ::
Cone height, h = 12 cm
Diameter of cone, d = 10 cm
Hence, radius, r = diameter / 2 = 10/2 = 5cm
The volume of a cone = 1/3 πr²h
V = 1/3 * 3.14 * 5² * 12
V = 3.14 * 25 * 4
V = 314cm³
An unusually wet spring has caused the size of a mosquito population in some city to increase by 7 â% each day. If an estimated 18â0,000 mosquitoes are in the city on May 6. Find how many mosquitoes will inhabit the city on May 17 . Use y =18â0,000(1.07 )^ x where x is number of days since May 6 .
Answer:
378873
Step-by-step explanation:
Using the relation :
y = 180000(1.07)^x
x = Number of days since May 6 ;
y = Number of mosquitoes after x days
x = May 17- May 6 = 11 days
Therefore, number of mosquitoes inhabiting the city on May 17 will be :
y = 180000(1.07)^11
y = 180000 * 2.1048519522998348950643
y = 378873.351413970281111574
y = 378873 (nearest whole number).

Find the total surface area of the net below
Therefore ,answering the offered question, we can state that the figure's surface area is SA = 2(9 11+11 9+11 * 11), which equals SA = 638 in2.
What precisely is surface area?Surface area is a measure of how much space an object's surface takes up overall. The total area of a three-dimensional shape's surroundings is its surface area. Surface area refers to the total surface area of a three-dimensional shape. You may compute the contact area of a cube with six square faces by adding together their individual areas. Alternatively, you can use the following formula to name the box's dimensions: Surfaces (SA) = 21 h + 2 lw + 2 hw. A tri shape's surface area is calculated as the total amount of space it occupies.
Here,
Front = rear = 11*11
top = bottom = 9*11
sides = 11*9;
SA= 2(911+119+1111)
SA=2(9999 +121)
SA = 2(319) (319)
SA = 638 in²

[tex] \\ [/tex]
Explanation:The given equation is a quadratic equation. In other words, it is written in the form ax² + bx + c = 0, where a ≠ 0.
[tex] \\ [/tex]
We will solve this equation using the quadratic equation, which is the following:
[tex] \sf x = \dfrac{- b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
[tex] \\ [/tex]
First, let's identify the value of the coefficients a, b, and c:
a = 1b = -14c = 74[tex] \\ [/tex]
Then, substitute these values into the quadratic formula:
[tex] \sf x= \dfrac{-(-14) \pm \sqrt{(-14)^2 - 4(1)(74)}}{2(1)} = \dfrac{14 \pm \sqrt{-100}}{2} [/tex]
[tex] \\ [/tex]
Simplify the expression knowing that [tex] \sf \sqrt{-1} = i [/tex], and keep in mind the following property:
[tex] \Large{\boxed{\sf \sqrt{ab} = \sqrt{a}\sqrt{b} }} [/tex]
[tex] \\ [/tex]
[tex] \sf x= \dfrac{14 \pm \sqrt{100 \times (-1) }}{2} = \dfrac{14 \pm \sqrt{100} \times \sqrt{-1}}{2} = \dfrac{14 \pm 10 \times i }{2} \\ \\ \implies \boxed{\boxed{\sf x= 7 \pm 5i}} [/tex]
[tex] \\ [/tex]
Therefore, the two complex conjugate roots of this equation are x = 7 + 5i and x = 7 - 5i.

Which property of real numbers is utlities by rewriting 11x+5xy as x(11+5y)
9514 1404 393
Answer:
distributive property
Step-by-step explanation:
The distributive property of multiplication over addition tells you ...
a(b +c) = ab +ac
This works both ways, allowing you to eliminate or add parentheses as may be needed.
The common factor of ...
11x +5xy
is x. It may be factored out according to the distributive property to give ...

A game is played with a spinner on a circle, like the minute hand on a clock. The circle is marked evenly from 0 to 100, so, for example, the 3:00 position corresponds to 25, the 6:00 position to 50 and so on. The player spins the spinner, and the resulting number is the number of seconds he or she is given to solve a word puzzle. If 100 players are randomly selected, what is the approximate probability that the average time these players will get to solve the puzzle is between 44 and 56 seconds
Answer:
P( 44 < X < 56 ) = 0.12
Step-by-step explanation:
Number of seconds one gets to solve the puzzle ( X )
E( X ) = 100 + 0 ) / 2 = 50
Var ( X ) = 833.3333
бx = √833.3333 = 28.868
Determine The approximate probability
P( 44 < X < 56 ) = Δ time given / number of players selected
P( 44 < X < 56 ) = (56 - 44) / 100
= 12 / 100 = 0.12
