3.6 * 10 = 36
Answer:
36
Step-by-step explanation:
if a = 3.6 and b= 10 and if we want to find ab we will just multiply them
3.6 x 10 = 36
(If you multiply a decimal by 10, the decimal point will move one place to the right. If you divide a decimal by 10, the decimal point will move one place to the left. If you multiply or divide by any power of 10, it will move a number of spaces equal to the number of 0's.)

County Middle School is buying pizza for all of its students. Each pizza has 8 slices. Each student will receive 1 slice. There are 700 students at County Middle School. How many pizzas will the school need to buy?
Answer:
88 at least
Step-by-step explanation:
So, if you need to give each student a slice remainders round up to the nearest whole number. So first you simply divide 700/8 (Students/Pieces of pizza per slice) and get 87.5. Then you round up to 88 since you cannot buy half a pizza (that's weird). You will have 4 extra slices to feed the teachers btw.

I WILL MARK BRAINLIST! TIS IS SIMPLE PROBABILITY. A bag of game markers contain 4 red markers, 5 blue markers, 3 yellow markers, and 3 green markers. If Mario reaches into the bag and pulls out a game marker without looking, what is the probability he will NOT pull out a blue game marker?
A. 1/2
B. 1/3
C. 4.15
D. 2/3
Answer: D. 2/3
Step-by-step explanation:
There are 15 markers in total. Out of these 15 markers, there are 5 blue ones.
If Mark reaches into a bag to pull out one marker and hopes it is not blue, there would be a 2/3 probability as 2/3 of the markers are not blue.
3. The sales director a manufacturer decides to try out two different methods of distributing and seling a new video game. The game is sold to a retailer for a net profit of $9.90 on each game . The game is also sold at the factory outlet for a net profit of $10.99 on each game. If 500 games are sold by the outlet, many more would have to be sold by the retailer in order for the profit to be about equal
Answer:
The number of games that need to be sold to the retailer in order for the profit to be about equal is approximately 555 games
Step-by-step explanation:
The given parameters are;
The net profit at which each game is sold to a retailer = $9.90
The net profit at which each game is sold at the factory outlet = $10.99
The number of units sold by the outlet = 500
The amount in profit from selling at the factory outlet = 500 × $10.99 = $5,495.00
The number of games that need to be sold to the retailer in order for the profit to be about equal is given as follows;
Let "x" represent the number of games that need to be sold to the retailer in order for the profit to be about equal
Therefore, we have;
x × $9.90/game = $5,495.00
x = $5,495.00/($9.90/game) = 555.[tex]\overline {05}[/tex] games ≈ 555 games
Therefore, the number of games that need to be sold to the retailer in order for the profit to be about equal = x ≈ 555 games.

How would you solve this?
Answer:
For the equation, you should subtract 2x on both sides to get -y = -2x - 4. Flip the y's negative sign to get a proper function which is y = 2x + 4. The y-intercept is at (0, 4) and each unit will move two units up along the x-axis.

Answer:
A
Step-by-step explanation:
Find the formula for the area A and the perimeter P of the shape shown find the area and perimeter when R is 5 cm find R when A is 100cm2 find r when P is 50cm find the value of r that makes A = p numerically
Answer:
1)Area; A = ¼πr²
Perimeter; P = πr/2 + 2r
2)A = 19.63 cm²
P = 17.85 cm
3) r = 8.885 cm
4) r = 14 cm
Step-by-step explanation:
This is a quadrant of a circle. Thus;
Area of a circle is πr². A quadrant is a quarter of a circle. Thus;
Formula for Quadrant Area is; A = ¼πr²
A) Perimeter of a circle is 2πr. Thus, perimeter of a quadrant is a quarter of the full circle perimeter.
Formula for the quadrant perimeter in the image given is;
P = 2πr/4 + 2r
P = πr/2 + 2r
B) When r is 5 cm;
A = ¼π(5)²
A = 19.63 cm²
P = π(5)/2 + 2(5)
P = 17.85 cm
C) when A is 100cm²:
¼πr² = 100
r² = 100 × 4/π
r² = 78.9358
r = √78.9358
r = 8.885 cm
D) when P = 50 cm.
50 = πr/2 + 2r
50 = (½π + 2)r
r = 50/(½π + 2)
r = 14 cm
if the daimeter of a solid cylinder with lenght 140cm is 8cm , find its curved surface area ,
Answer : The curved surface area of solid cylinder is [tex]3520cm^2[/tex]
Step-by-step explanation :
As we are given that:
Diameter of solid cylinder = 8 cm
Length or Height o solid cylinder = 140 cm
Formula used to calculate the curved surface area of cylinder is:
Curved surface area of cylinder = [tex]2\pi r\times h[/tex]
where,
r = radius of cylinder
h = height or length of cylinder
Radius of cylinder = [tex]\frac{Diameter}{2}=\frac{8cm}{2}=4cm[/tex]
Now putting all the given values in above formula, we get:
Curved surface area of cylinder = [tex]2\times \frac{22}{7}\times 4cm\times 140cm[/tex]
Curved surface area of cylinder = [tex]3520cm^2[/tex]
Therefore, the curved surface area of solid cylinder is [tex]3520cm^2[/tex]
Given:
Diameter of a solid cylinder = 8cm
Length (height) of cylinder = 140 cm
To find:
The curved surface area of the cylinder.
Solution:
We have,
Diameter = 8cm
Radius = [tex]\dfrac{8}{2}=4\text{ cm}[/tex]
Height = 140 cm
Curved surface area of a cylinder is
[tex]CSA=2\pi rh[/tex]
where, r is radius and h is height.
Putting r=4 and h=140 in the above formula, we get
[tex]CSA=2\times \dfrac{22}{7}\times 4\times 140[/tex]
[tex]CSA=2\times 22\times 4\times 20[/tex]
[tex]CSA=3520[/tex]
Therefore, the curved surface area of the cylinder is 3520 square cm.

Answer:
The first option
Step-by-step explanation:
The equation of g(x) is g(x) = [tex]10^{3 - x[/tex]
Option A is the correct answer.
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape and size.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
From the graph, we see that,
The coordinates in the line g(x) are (5, 100) and (4, 10).
Now,
g(x) = [tex]10^{x - 3[/tex] ______(1)
Substituting (5, 100) and (4, 10) in (1)
We get,
g(5) = [tex]10^{5 - 3[/tex] = 100
g(4) = [tex]10^{4 - 3[/tex] = 10
This is true.
Thus,
The equation of g(x) is g(x) = [tex]10^{3 - x[/tex]
