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

Answer:
A
Step-by-step explanation:
An isosceles right triangle has two legs the length x and the hypotenuse equal to x√2.
f(-4); f(x) = x2 + x - 4
Answer: 8
Step-by-step explanation: In this problem,
we're asked to find f(-4) or the value of the function when x = -4.
To find the value of the function when x = -4,we simply plug in a -4 for
the x in our function and we have (-4)² + (-4) - 4 or 16 + -4 - 4 which is 8.
So f(-4) = 8.
sian thinks of a number.
it's value is increased by 25%.
express the original number as a percentage of the increased number
will give brainliest
Answer:
80%
Step-by-step explanation:
original: 1
Increase 25%: 1.25 if this number becomes 1
1 : 1.25 = x : 1
x = 1 / 1.25 = 0.8 (80%)
check: 0.8 x 1.25 = 1

PLEASE HELP ME Determine the premiter of the figure . Use 3.14 for PI Round to the nearest tenth. Numbers are 10 in and 15in
Answer:
5[tex]\pi[/tex]+40
Step-by-step explanation:
perimeter of circle=2[tex]\pi[/tex]r
so 5 is r(radius)
so 10[tex]\pi[/tex], but since it’s semicircle, you have to divide by 2, so
5[tex]\pi[/tex]
perimeter of rectangle=15+10+15 because you don’t count the inside, so that equals 40
so 5[tex]\pi[/tex]+40

Answer:
B rectangle
Step-by-step explanation:
solve: |2x-1| ≥ 4x+3
Step-by-step explanation:
consider the sign as equals then
move 2x right side 3 on left
solve it
answer is 2
Question is: 2x - 1 >= 4x + 3
First, join the like terms together.
-> So 2x moves into 4x, meaning it becomes negative -2x on the other side.
-> The number 3 moves into the other side which also becomes negative.
Now the equation will look like this:
- 3 - 1 >= 4x - 2x
- 4 >= 2x
Put 2 on the other side with - 4, and it will divide (not plus or minus as 2 was combined with an unlike term).
It looks like this now:
- 4/2 >= x
- 2 >= x
This is the answer.
Washington Middle School is painting a circle on their playground with a radius of 12 feet. What will be the total area of the circle, in square feet?

A remodeling project calls for sanding a chair with a disk sander. The sanding disk used on the sander has a radius of 4 inches. Find the area of the disk. Use 3.14 for \large \pi
Answer:
the area of the disk is 50.24 inches^2
Step-by-step explanation:
The computation of the area of the disk is as follows:
As we know that
The area of the circle is
= πr^2
= 3.14 × 4^2
= 3.14 × 16
= 50.24 inches ^2
hence, the area of the disk is 50.24 inches^2

Ellen has a coupon for 1.55 off a loaf of bread. The regular price of bread is 4.63. The loaf is cut into 14 slices. What is the price per slice if Ellen uses her coupon?
Answer:
0.22 or 22 cents
Step-by-step explanation:
4.63 (original bread price) - 1.55 (coupon) = 3.08
divided by 14 slices of bread is 22 cents
Answer:
$0.22 per slice
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightStep-by-step explanation:
Apply the coupon to the loaf of bread first. $1.55 off a loaf of bread means subtracting this amount from the original price of bread.
$4.63 - $1.55 = $3.08If the loaf is cut into 14 slices, we should divide the loaf of bread's new price by 14.
$3.08 / 14 = $0.22The price per slice if Ellen uses her coupon is $0.22 per slice.

Enter the ordered pair for the vertices for 180°,0)(QRST).
Q
o
S
IR
O Q' = (-1,-3) R' = (-3,3 ) S'= (0,2)T' =(2, -1)
OQ' = (-1,3) R' = (-3,-3) S'=(0, -2)T' =(2, 1)
Q' = (1, -3) R' =(3,3) S' = (0,2)T' = (-2,-1)
Answer:
The ordered pair for the vertices for r₍₁₈₀ ₀₎(QRST), is given as follows;
Q' = (-1, -3) R' = (-3, 3) S' = (0, 2) T' = (2, -1)
Step-by-step explanation:
The coordinates of he vertices of the triangle QRST are;
Q(1, 3), R(3, -3), S(0, -2), T(-2, 1)
A rotation of a point with coordinates (x, y) 180° about the origin gives;
The coordinate of the point of the preimage before the rotation = (x, y)
The coordinate of the point of the image after the rotation = (-x, -y)
Therefore we have;
The image of point Q(1, 3) after 180° rotation = Q'(-1, -3)
The image of point R(3, -3) after 180° rotation = R'(-3, 3)
The image of point S(0, -2) after 180° rotation = S'(0, 2)
The image of point T(-2, 1) after 180° rotation = T'(2, -1)
The ordered pair for the vertices for r₍₁₈₀ ₀₎(QRST), is therefore, Q'(-1, -3), R'(-3, 3), S'(0, 2), and T'(2, -1);
Q' = (-1, -3) R' = (-3, 3) S' = (0, 2) T' = (2, -1).

if zaeirr has 10 dogs and lamarr has 2 dogs how many more dogs does zaeirr have than lamarr?
Answer: 8
Step-by-step explanation:
For this problem, we would have to subtract the larger number of dogs by the smaller number of dogs. Zaierr has 10 dogs, and Lamarr has 2 dogs. We would have to subtract the number 10 by the number 2 to get our answer.
10 subtracted by 2 is equal to the number 8.
The answer to our question is 8.
