a teacher wishes to keep the students books in the cardboard which is 69.9cm long,24cm wide and 36.01cm high estimate how many exercise books he can put if each exercise book is 22cm long 19.5cm wide and 0.9cm thick
Answer:
156
Step-by-step explanation:
We are given that
Length of cardboard, l=69.9 cm
Width of cardboard, b=24 cm
Height of cardboard, h=36.01 cm
Length of book, l=22 cm
Width of book, b=19.5 cm
Thickness of book, h=0.9 cm
Volume of cuboid=lbh
Using the formula
Volume of cardboard=[tex]69.9\times 24\times 36.01 cm^3[/tex]
Volume of one book=[tex]22\times 19.5\times 0.9 cm^3[/tex]
Number pf exercise book=[tex]\frac{volume\;of\;cardboard}{volume\;of;one\;book}[/tex]
Number of exercise book=[tex]\frac{69.9\times 24\times 36.01}{22\times 19.5\times 0.9}[/tex]
Number of exercise book=156
What is the solution of the system of equations y=5.69x+25 y=9.49x+6
Given :
A system of equations y = 5.69x + 25 and y = 9.49x + 6.
To Find :
The solution of the system of equation.
Solution :
Subtracting equation 2 by 1, we get :
y - y = ( 9.49x + 6 ) - ( 5.69x + 25 )
0 = 3.8x - 19
x = 5
Putting value of x in equation 1, we get :
y = (5.69×5) + 25
y = 53.45
Therefore, the solution of the system of equations is ( 5, 53.45 ).
Which shows a correct procedure to simplify 3V8?
Answer:
2√2
Step-by-step explanation:
If you mean 3√8, this is how you would simplify:
Know that √8=√(4*2)
Thus, √(4*2)=(√4)*(√2)=2√2
So 3√8 simplified is 2√2
A painter is painting a rectangular wall that measures 23.6 ft by 19.2 ft. Each gallon can of paint covers 200 square feet. What are the fewest gallons needed to paint the wall?
Answer:
3 gallons
Step-by-step explanation:
Length of the rectangular wall = 23.6 feet
Width of the rectangular wall = 19.2 feet
Surface area of the wall = 23.6 × 19.2
= 453.12 square feet
∵ 200 square feet of the wall is covered by the amount of paint = 1 gallon
∴ 1 square feet of the wall will be covered by the amount of paint = [tex]\frac{1}{200}[/tex] gallons
∴ 453.12 square feet will require the amount of paint = [tex]\frac{453.12}{200}[/tex]
= 2.2656 gallons
Therefore, minimum 3 gallons will be required to paint the wall.
5 In a scale drawing of an airplane, 1 inch equals 3 meters. The length of the actual plane is 17 meters. What is the length of the plane in the scale drawing?
Answer: 5 2/3 inches
Step-by-step explanation:
From the question, we are informed that the scale drawing of an airplane is:
1 inch = 3 meters.
Since the length of the actual plane is 17 meters, the length of the plane in the scale drawing will then be:
= 17/3
= 5 2/3 inches
Use the FOIL Method to find (w+9)(w+6)
Answer:
Step-by-step explanation:
First, outside, inside, last.
w*w
6*w
9*w
9*6
[tex]w^2+15w+54[/tex]
Answer: w^2 + 15w + 54
Step-by-step explanation:
FOIL = first, outside, inside, last.
First —> multiply first numbers of each parentheses.
Outside —> multiple the OUTSIDE numbers in each parentheses (first number in the first parentheses, second number in the second parentheses.
Inside —> multiply the INSIDE numbers in each parentheses (the second number in the first parentheses, first number in the second parentheses).
Last —> multiply second number of each parentheses.
(W + 9)(w + 6)
F = w^2
O = 6w
I = 9w
L = 54
W^2 + 6w + 9w + 54
W^2 +15w + 54

Answer:
a) 22 minutes
b) 9 minutes
c) 27 minutes
Step-by-step explanation:
a) Grace arrives at Stavely station at 14:30 and she wants to go to Kendal. The next train to Kendal is at 14:52 which is 22 minutes later.
52 - 30 = 22
Grace will have to wait 22 minutes for the train.
b) Since Grace is departing from the station at 14:52 the next train that reaches the station she's heading to is at 15:01.
The journey will take 9 minutes from Stavely to Kendal.
c) Sam left Windermere at 14:17 so he reaches Kendal at 14:34 and since Grace will reach at 15:01. Sam will have to wait 27 minutes until Grace arrives.
Calculations:
60 - 34 = 26
26 + 1 = 27
Sam will have to wait 27 minutes until Grace arrives.

Stephanie and Jose both want to buy a skateboard. Stephanie has already saved $25 and plans to save $5 a week until she can buy the skateboard. Jose has $16 and plans to save $8 a week. How many weeks will it take for them to have the same amount of money and how much will they have?
(Also if u can pls type out ur answer like "10 weeks and $100" hehe)
Answer: 3 weeks and $40
Step-by-step explanation:
Let the number or weeks taken for them to have same amount be represented by x.
The information given in the question can be presented as an equation as:
Stephanie = 25 + 5x
Jose = 16 + 8x
We then equate them together
25 + 5x = 16 + 8x
25 - 16 = 8x - 5x
3x = 9
x = 9/3 = 3
The number of weeks is 3
The amount of money that they'll have will be:
= 25 + 5x
= 25 + 5(3)
= 25 + 15 = $40

A tree is growing at a constant rate. It is recorded that at the 7th year since it was planted it was at a height of 25 feet. It was recorded again at the 10th year since it was planted and it was at a height of 31 feet. How much does the tree grow every year?
9514 1404 393
Answer:
2 feet per year
Step-by-step explanation:
In the 3 years between the 7th and 10th, the tree grew 6 feet from 25 ft to 31 ft. The rate of growth is ...
(6 ft)/(3 yr) = (6/3) ft/yr = 2 ft/yr

What is system of equations?A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.
According to the question,
1. The system contains infinitely many solutions.
This stands wrong because according to the graph, there exists only one solution- where the lines intersect.
This would only be correct if the lines never intersect.
2. A solution to the system exists (-1, -2).
This exists true because this stands as the only point where the lines intersect.
3. A solution to the system exists (0, -1).
This is correct because the y-intercept for the red line stands at -1 and the slope of the equation is 1.
4. One of the equations exists 3x+y = -5.
If you put this into slope-intercept form, you will discover that the equation exists y =-3x -5.
This stands correct because the y-intercept of this stands -5 and the slope of this stands -3.
