Mila built a wooden toy bin with a lid to sell in her store. The bin is shaped like a rectangular prism and measures 2 feet long,1 foot wide,and 2 feet deep. To make the wood darker,she stained the outside of the toy bin including the top of the lid and the bottom of the bin. What is the area that mila stained?
The rectangular prism having a length of 1 feet, width of 2 feet and that
is 1 feet deep, gives the area Mila stained as 8 square feet.
How can the area that Mila stained be found?The given dimensions of the rectangular prism bin are;
Length of the bin = 2 foot
Width of the bin = 1 feet
Depth of the bin = 2 feet
Required:
The surface area of the rectangular prism bin.
Solution:
The surface area, S. A., of the rectangular prism bin is given as follows;
S. A. = Length × Width + Depth × Width + Length × Depth
Which gives;
S. A. = 2 × 1 + 2 × 1 + 2 × 2 = 8
The surface of area Mila stained, S. A. = 8 ft.²Learn more about surface area of a rectangular prism here:

We see : 4x - 5y = -20
We can write the negative form of 4x - 5y by switching the signs : - (4x - 5y ) = -4x + 5y
Since -4x + 5y is the negative form of 4x - 5y, the result should also be the opposite : 20
And -4x + 5y is indeed 20, so the answer is infinitely many solutions.
Answer:
infinitely many solutions
Step-by-step explanation:
4x - 5y = - 20 → (1)
- 4x + 5y = 20 → (2)
add (1) and (2) term by term
0 + 0 = 0
0 = 0 ← true statement
this indicates the system has infinitely many solutions

Answer:
The difference between a two step equation and a inequality equation is that two step equation you can isolate the variable and get the answer. However in a inequality equation you can only compare, for example A > 7
Step-by-step explanation:
A inequality compares not giving a clear answer. A two step equation lets you find a clear answer.

Can the side lengths of 7, 10, and 9 form a triangle?
========================================================
Explanation:
Add the first two sides to get 7+10 = 17 which is larger than the third side (9)Add the first and last sides to get 7+9 = 16 which is larger than the second side (10)Add the last two sides to get 10+9 = 19 which is larger than the first side (7)As that list above shows, adding any two sides results in a sum larger than the third remaining side. The conditions of the triangle inequality theorem have been met to allow for a triangle to be formed.
In general the triangle inequality theorem is:
a+b > ca+c > bb+c > aThe order doesn't matter. All that's important is that all three conditions are met.

Two car rental companies have the following payment plans: Cart: $90 per week and 15c per kilometre Renta: $110 per week and 10c per kilometre What is the maximum whole number of kilometres that can be travelled in one week with Carz if it is to cost less than it would with Renta?
Using linear function concepts, it is found that the maximum whole number of kilometres that can be travelled in one week with Carz if it is to cost less than it would with Renta is of 399.
What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.For each car, Cart and Renta, the linear functions are given by:
C(k) = 90 + 0.15k
R(k) = 110 + 0.1k
Cart will cost less than Renta if:
C(k) < R(k)
Hence:
90 + 0.15k < 110 + 0.5k
0.05k < 20
k < 400
Hence, the maximum whole number of kilometres that can be travelled in one week with Carz if it is to cost less than it would with Renta is of 399.

For the following system a) What is the value of x? b ) What is the value of y ?
Answer:
x = 12
y = -23
Step-by-step explanation:
to solve for this i think we have to do:
y = -3x + 13
-
y = -2x + 1
-----------------------
0 = -x + 12
-x = -12
x = 12
then i think.... i think you have to substitute to one of the equations
y = -3(12) + 13
y = -36 + 13
y = -23
then to check we substitute to the second equation
-23 = -2(12) + 1 ?
-23 = -24 + 1?
-23 = -23

Answer:
7598.8 [tex]cm^{2}[/tex]
Step-by-step explanation:
v (volume) = π[tex]r^{2}[/tex]h
v = 3.14 x [tex]11^{2}[/tex] x 20
v = 3.14 x 121 x 20
v = 7598.8
Answer:
7598.8 cm³
Step-by-step explanation:
Given :-
height = 20 cm
radius = 11 cm
value of π = 3.14
Formula to be used :-
Volume of cylinder = πr²h
Inputting the values :-
V = 3.14 x 11 x 11 x 20
= 3.14 x 121 x 20
= 3.14 x 2420
= 7598.8 cm³
