A chef takes c cartons of eggs from the refrigerator. Each carton contains 12 eggs. The chef wants to have a total of at least 50 eggs.
Answer: 5 cartons
Step-by-step explanation:
If the Chef wants to have a total of at least 50 eggs and each carton contains 12 eggs, divide 50 by 12 to find out the number of cartons needed and then round the number up:
= 50 /12
= 4.16
Round it up to the nearest 1:
= 5 cartons
This will ensure that there is at least 50 eggs because 5 * 12 = 60 eggs.
What is the surface area of the cylinder?
226.08 cm²
678.24 cm²
1,356.48 cm²
452.16 cm²
Answer:
452.16
Step-by-step explanation:
i got it right on test
The surface area of the cylinder is,
⇒ TSA = 452.16 cm²
We have to given that;
Height of cylinder = 6 cm
And, Diameter of cylinder = 12 cm
Hence, We get;
⇒ Radius of cylinder = 12 / 2 = 6 cm
We know that;
The formula for the total surface area of a given cylinder whose radius is r and height is h is,
TSA = 2πr (h + r)
Hence, We get;
TSA = 2πr (h + r)
TSA = 2 × 3.14 × 6 (6 + 6)
TSA = 37.68 × 12
TSA = 452.16 cm²
Thus, The surface area of the cylinder is,
⇒ TSA = 452.16 cm²

Kristin's Bikes rents bikes for $11 plus $2 per hour. Willie paid $23 to rent a bike. For how many hours did he rent the bike?
Define the variable, write an equation, and solve the equation.
Answer:
6
Step-by-step explanation:
Let x = number of hours.
Let y = cost.
The fixed cost is $11.
The cost per hour is $2.
For x hours, the cost per hour is 2x.
y = 2x + 11
23 = 2x + 11
12 = 2x
x = 6

An alloy consists of 13 parts of copper to 7 parts of zinc and 5 parts of Nickel what is the percentage composition of the alloy
Answer:
52% Copper, 28% Zinc, 20% Nickel
Step-by-step explanation:
Copper is 13 out of 13+7+5 = 25
13/25 = 52%
Zinc is 7 out of 25 so 28%
Nickel is 5/25 = 20%

What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. The Numbers constants, variables, operations, brackets can all be represented by mathematical symbol; which can also be used to indicate the logical syntax's order of operations and other features.
Therefore, each number as a single digit times a power of ten.

Answer:
a) x <= 15 b) x > 16.5 c) x < 34.5 d) x =/= 23
Step-by-step explanation:
For a), there is a shaded region for where 15 is, and the number line is going towards the left, so x will be less than but also equal to 15
For b), there is not a shaded region for where 16.5 is, but the number line is going towards the right, so x will be greater than 16.5
For c), there is not a shaded region for where 34.5 is, but the number line is going towards the left, so x will be less than 34.5
For d), there is not a shaded region for where 23 is, but the number line is going everywhere else so it is x =/= 23(x does not equal to 23)

a metal box that is in shape of cuboid has the following dimensions. the length is 9 inches, width is 2 inches and height is 1. 5 inches. find the total cost of silver coating the entire box if the cost of coating is $2.50 per Sq. inches
Given:
Length of a box is 9 inches, width is 2 inches and height is 1.5 inches.
The cost of silver coating is $2.50 per sq. inches.
To find:
The total cost of silver coating for the box.
Solution:
The total surface area of a cuboid is
[tex]A=2(lb+bh+hl)[/tex]
Where, l is length, b is breadth and h is height.
Putting [tex]l=9,b=2,h=1.5[/tex], we get
[tex]A=2(9\times 2+2\times 1.5+1.5\times 9)[/tex]
[tex]A=2(18+3+13.5)[/tex]
[tex]A=2(34.5)[/tex]
[tex]A=69[/tex]
So, the total surface area of the box is 69 square inches.
Cost of silver coating is $2.50 per sq. inches. So, the cost of silver coating for the box is
[tex]Cost=69\times 2.50[/tex]
[tex]Cost=172.50[/tex]
Therefore, the cost of silver coating for the box is $172.50.
