Answer:
13.6%
Step-by-step explanation:
Step 1
Find the actual volume of the box
Volume = Length × Width × Height
You measure the box and find that it has a length of 10 inches, a width of 9 inches, and a helght of 4.5 inches.
Volume = 10 inches × 9 inches × 4.5 inches
Volume of the box = 405 cubic inches
Step 2
Calculate the percent error
|Estimated value - Actual value|/Actual value ×100
Estimated value= 350 cubic inches
Actual value = 405 cubic inches
= |350 - 405|/405 × 100
= |-55|/405 × 100
= 55/405 × 100
= 13.580246914%
Approximately = 13.6%
The Percent error is 13.6%
3x - y = 4 and 7x + 2y = 18
<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3
Answer: (3x - y = 4)
x = 1/3y + 4/3
y = 3x − 4
Answer: (7x + 2y = 18)
x = -2/7y + 18/7
y = -7/2x + 9

10x-6=3(x+1/2)
Answer:
15/14
Step-by-step explanation:
3(x+1/2)
10x-6=3x+3/2
7x=3/2+12/2
7x=15/2
x=15/2*1/7
x=15/14

which is the greatest common factor of 12 and 88
4 will be your answer
Explanation:
The factors of 12 are 1, 2, 3, 4, 6, 12
The factors of 88 are 1, 2, 4, 8, 11, 22, 44, 88.
So, as we can see, the Greatest Common Factor or Divisor is 4, because it is the greatest number that divides evenly into all of them.
hope it helped :D
Answer:
4
Step-by-step explanation:
Can somebody help me with this problem 22/35+35x3
22/35+35x3
Division comes first.
22/35=0.62857142857 or just 0.629, or 0.63
0.63+35x3
Now we multiply.
35x3=105
So now we have 0.63+105.
Lastly, we add.
0.63+105=105.63
The answer is 105.63.

Ap calculus
9514 1404 393
Answer:
(b) -15
Step-by-step explanation:
The area under the curve from -5 to +5 can be divided into two trapezoids. The one from x=-5 to x=1 has an area of ...
A = 1/2(b1 +b2)h = 1/2(1 +6)(5) = 17.5
The one from x=1 to x=5 has an area of ...
A = 1/2(4 +3)(-1) = -3.5
So, the total area from x=-5 to x=+5 is 17.5 -3.5 = 14. This is the amount by which f(x) increases from f(-5) to f(5). That is ...
f(-5) +14 = -1
f(-5) = -15

Find the missing term in the geometric sequence : 8 , 20 , 50, 125 , ____
Answer:
312.50
Step-by-step explanation:
8 , 20 , 50, 125 , 312.50
First term, a = 8
Second term, ar = 20
Find common ratio, r
Substitute a = 8 into second equation
ar = 20
8r = 20
r = 20/8
r = 2.5
Find the fifth term
ar⁴
= 8 * 2.5⁴
= 8 * 39.0625
= 312.50
Fifth term, ar⁴ = 312.50

Answer:
c (all real numbers)
Step-by-step explanation:
The first inequality has the solution ...
3 + v ≤ -4
v ≤ -7 . . . . . . . subtract 3 from both sides
__
The second inequality has the solution ...
-2v ≤ 14
v ≥ -7 . . . . . . . divide by -2. Division by a negative reverses the inequality
__
So, the solution to the compound ...
v ≤ -7 or -7 ≤ v
is every number — all real numbers. The graph of that is the entire number line, as in choice C.
solve the pair simultaneous equations
2x+y=7
x -2y=1
