Given :
The librarians need to pack 2 tons of books into cardboard boxes. Each box can safely hold about 25 pounds of books. If they already packed 50 boxes.
To Find :
How many more boxes should they expect to use.
Solution :
We know, 1 ton = 2000 pounds
So, 2 ton = 4000 pounds
Minimum number of boxes required for safe handling :
[tex]n=\dfrac{4000}{25}\\\\n=160[/tex]
So, total 160 boxes required.
Therefore, 160 - 50 = 110 many more boxes should they expect to use.
Hence, this is the required solution.
Answer:
110 more boxes
Step-by-step explanation:
Find the area of the shape.
Suppose v varies directly as g, and v = 36 when g = 4. Find v when g = 11
Step-by-step explanation:
v=kg
36=k×4
k=36/4
k=9
v=9×11
v=99
Find the slope of
(-16,3), (13,8)
Answer:
= 5/29
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( 8-3)/(13 - -16)
= ( 8-3)/( 13+16)
= 5/29
-3z-1=1-7z simplify
Answer:
z = 1/2
Step-by-step explanation:
Step 1: Write equation
-3z - 1 = 1 - 7z
Step 2: Solve for x
Add 7z to both sides: 4z - 1 = 1Add 1 to both sides: 4z = 2Divide both sides 4: z = 1/2Step 3: Check
Plug in z to verify it's a solution.
-3(1/2) - 1 = 1 - 7(1/2)

Step-by-step explanation:
suppose three Riders rode a total of 260 Mi if they use a total of 18 horses and rode each horse to the same number of miles how many miles did they ride before replacing the horse
Answer:
14.3 - Not entirely sure?
Step-by-step explanation:
So you first divide 260 by 3 (the riders), and if they used a total of 18 horses together you then divide them by 3 as well. You get the answer from 260 and 3 (which would be 86) also the answer from 18 and 3 (which would be 6) and divide them together (I know, lots of dividing) and there's your answer! 14.3
plz ive been stuck on this for an hour plzzz help?
Answer:
2x<10
Step-by-step explanation:
Try to figure it out from there
Hint: divisionAnswer:
[tex]x < 5[/tex]
Look at attachment for graph.
Step-by-step explanation:
Solving the inequality just has us isolate the x value.
[tex]-9 + 2x < 1[/tex]
Add 9 to both sides to cancel out -9
[tex]2x < 10[/tex]
Finally, divide both sides by 2 to get rid of the 2 on the x.
[tex]x < 5[/tex]
To graph this, you will just add an open circle on 5 and shade every number to the left of it.
Order these numbers from largest at the top, to smallest at the bottom.
1.57x10^-4
4.5x10^3
1.3x10^1
987
Step-by-step explanation:
Question:-Order these numbers from largest at the top, to smallest at the bottom.
1.57x10^-4
4.5x10^3
1.3x10^1
987
We can see that:-
The exponent with highest power is the largest number.
Here, the largest number is
[tex]1.3 \times 10 ^3[/tex]
Next, is [tex]987[/tex]
Smaller than this, next is :-
[tex]1.3 \times 10^1[/tex]
A number with negative power is smaller.
So, last is
[tex]1.57 \times 10^{-4}[/tex]
Hope it helps :)

Two shelters offers dog adoption twice a year ruff had 123 dogs adoption in january 196 fogs adoption in July barks had 78 dogs adoption in January and 135 adoption in July estimates the difference in the number of dogs adoption at each shelter that year
Answer:
106
Step-by-step explanation:
ruff
123 dogs adoption in january
196 dogs adoption in July
Total adoption for the year = 123 + 196
= 319 adoptions
barks
78 dogs adoption in January
135 adoption in July
Total s like adoption for the year = 78 + 135
= 213 adoptions
Difference in the number of dogs adoption at each shelter that year
= Ruff total adoption for the year - Bark's total adoption for the year
= 319 adoptions - 213 adoptions
= 106
The difference in the number of dogs adoption at each shelter that year is 106
what's the distance between (-9,2) and (5,-4)?
Answer: Exact Form: d= 2√58
Decimal Form: 15.23154621...
Step-by-step explanation:
Distance formula: d=√(x2-x1)^2 + (y2-y1)^2
d=√(5- -9)^2 + (-4 - 2)^2
Exact Form: d= 2√58
Decimal Form: 15.23154621...
The distance between two points (-9,2) and (5,-4) is 15.23 units.
What is the distance between two points?The distance between two points is defined as the length of the line segment between two places representing their distance. Most significantly, segments that have the same length are referred to as congruent segments and the distance between two places is always positive.
The formula of distance between two points is P(x₁, y₁) and Q(x₂, y₂) is given by: d (P, Q) = √ (x₂ – x₁)² + (y₂ – y₁) ².
We have to determine the distance between (-9,2) and (5,-4)
As per the question, substitute the known values in the formula,
d = √ {(-9 – 5)² + (2 – (-4))²}
d = √ {(-14)² + (6)²}
d = √ {196 + 36}
d = √232
d ≈ 15.23
Thus, the distance between the given two points is 15.23 units.

Aggie is an australian exchange sudent in china, and she currenly has 14,000 yuan in her bank account. If the exchange rate changes from 1 australian dollar to 6.21 yuan to 1 australian dollar 6.37 chinese yuan, what happens to the value in australian dollars of the money in aggies bank account
Step-by-step explanation:
Amount in Aggie bank account = 14,000 yuan
Initial exchange rate:
1 Australian dollar = 6.21 yuan
Initial amount in Australian dollars will be;
x aus dollar = 14,000 yuan
cross multiply
6.21x = 14,000
x = 14,000/6.21
x = 2,254.428 australian dollars
If the exchange rate increases to 6.37 Chinese yuan, her new balance in Australian dollars will be y;
1 Australian dollar = 6.37 yuan
y Australian dollar = 14,000 yuan
cross multiply
6.37y = 14,000
x = 14,000/6.37
y = 2,197.80 Australian dollars
The change in her account balance due to increase in exchange rate is y-x
y-x = 2,197.80 - 2,254.428
y-x = -56.626 aus dollars
This negative values shows a decrease in her account balance by 56.626 aus dollars due to increase in the exchange rate.

13. Find g(f(5)) if g(x) = 2x - 7 and F(x) = -4x - 7
Answer:
g(f(5)) = - 61
Step-by-step explanation:
Evaluate f(5) then substitute the value obtained into g(x) , that is
f(5) = - 4(5) - 7 = - 20 - 7 = - 27 , then
g(- 27) = 2(- 27) - 7 = - 54 - 7 = - 61

The length of a rectangle is twice its width. The perimeter of the rectangle is 121 feet.
Plzzz help
Answer:
[tex]121=6w[/tex]
Step-by-step explanation:
Formula for perimeter of a rectangle:
[tex]P=2l+2w[/tex]
[tex]w[/tex] = width
[tex]l[/tex] = length
Since the length is twice the width,
[tex]l=2w[/tex].
So, plugging these values into the formula, as well as the given perimeter of 121 feet, we get,
[tex]121 = 2(2w)+2w[/tex]
And after some simplification, we are left with,
[tex]121 = 6w[/tex]

Prove AC = BC
Step-by-step explanation:
Funny question!
AE=BD
A= BD/E
Then,
CD=CE
D=E
therefore, A=BE/E (SINCE, D=E)
So, A=B
or, AC= BC (multiplying by C)
