Well first, you have to know that there are 12 inches in a foot so, that's 12 / 3 = 4, so that means that for every foot, there are 4 books. The books are 5 feet tall so 4 x 5 = 20. Your answer is: 20 books are in a stack.
Answer:
Step-by-step explanation: I would do 5x12 because there are 12 inches in one foot so 5x12 is 60 so there is 60 inches

Logan measured a line to be 7.4 inches long. If the actual length of the line is 7.7 inches, then what was the percent error of the measurement, to the nearest tenth of a percent?
Answer:
3.9%
Step-by-step explanation:
Percentage error
[tex] = \frac{7.7 - 7.4}{7.7} \times 100 \\ \\ = \frac{0.3}{7.7} \times 100 \\ \\ = \frac{300}{77} \\ \\ = 3.8961039 \\ \\ = 3.9 \% [/tex]
A group of friends wants to go to the amusement park. They have no more than $175
to spend on parking and admission. Parking is $12.50, and tickets cost $16.25 per
person, including tax. Write and solve an inequality which can be used to determine
2, the number of people who can go to the amusement park.
Answer: 10 people can/ 12.50+16.25x is less than or equal to 175
Step-by-step explanation: so parking is constant since it doesn't change. ticket price however is affected by a variable which represents ticket per person which is shown as 12.50(parking)+16.25x where x would equal the max amount of people while respecting the given 175 limit we cannot go over
Answer:
"Can you add the equation?"
That's exactly what I'm asking, I asked a question that's very similar to this one, but nobody seems to know an equation that can be created :(
Step-by-step explanation:
If I solve the problem and create an equation, I'll let you know
I got you.
Inequaility : 12.50 + 16.25x ≤ 174
I think it's gonna be
x ≤ 10
What is the perimeter of a square with a side length of 2x?
Please help :)
Answer:
8x
Step-by-step explanation:
perimeter is sum of all sides
square has 4 equal sides
each side measures '2x'
2x + 2x + 2x + 2x = 8x or 4(2x) = 8x

Find the area of the above parallelogram
Answer:
30 units²
Step-by-step explanation:
The area (A) of a parallelogram is calculated as
A = bh ( b is the base and h the perpendicular height )
Here
b is the horizontal measure between 2 red points, that is 6
h is the vertical measure from the lower left point to the other horizontal line, that is 5, then
A = 6 × 5 = 30 units²
Factor out the coefficient of the variable -3.6m + 10.8
Answer: -1
Step-by-step explanation: First, factor out 3.6. You should get -m+3. Since the coefficient is just the number being multiplied to the variable (which is m here), your coefficient should be -1 because m is being multiplied to -1 to make -m. Hope this helps!

Answer:
im not sure but i think its correct (like 80-90%)(but probably not but u can use this method to find the correct answer)
Step-by-step explanation:
a) 25+40= 65 (x) 10= 650/2= 325
b) 325 (x) 50= 16,250cm
c) 325 (x) 2= 650
20 (x) 50= 1000
50 (x) 40= 2000
15 (x) 50= 750
25 (x) 50= 1250
then, just add eveything above should be 5,650cm^2

To find the solutions (or, in other words, zeroes) of a quadratic function/equation we use the discriminant (the part that's inside the square root of the quadratic formula, [tex]b^2-4ac[/tex].)
If the discriminant is smaller than 0, there are no zeroes
If the discriminant is equal to 0, there is one zero
If the discriminant is larger than 0, it has two zeroes
The discriminant is commonly denoted as [tex]\Delta[/tex].

The Maximus Electric Company will increase employee's yearly wages by 2.5% next year. An employee whose
yearly wages this year total $45,000 will earn what total yearly wages next year
Answer:
46,125
Step-by-step explanation:
2.5% = .025
45,000 * .025 = 1,125
45,000 + 1,125 = 46,125

Kerri likes to share her candy with her friends. For every two pieces she eats, she makes sure she
gives five pieces to her friends. If Kerri has given 35 pieces away this week, how many pieces has
she eaten? Show how you arrived at your answer.
Can you guys help me please
Answer:
she has eaten 14 times because each time she ate 2 she gave away 5, that means she had to give out 7 times- 7*5 =35 so all you have to do is multiply 2 by 7 because she ate TWO each time she gave out 5!

Answer:
Line m and n are parallel lines that are intersected by a line
This means that corresponding angles in each line are equal to each other
This means that angle (3x+58) is equal to (5x)
now, we can solve for x and from there find the angle measure
(3x+58)=5x
3x-3x+58=5x-3x
58=2x
58/2=2x/2
29=x
if 29=x then 5(29)=5x
the angle measure of these angles is 145
Step-by-step explanation:
Answer:
Step-by-step explanation:
m // n and they are intersected by transversal.
Corresponding angles are equal
5x = 3x + 58
5x - 3x = 58
2x = 58
x = 58/2
x = 29

Answer:
Option B
Step-by-step explanation:
In a triangle , sum of measure of any 2 sides is always greater than the measure of the third side. So
[tex]5 + 12 > k[/tex]
[tex] = > 17 > k[/tex]
Hence the measure of k is less than 17.
In the triangle , measure of the longest side is 12 cm. As we know that sum of measure of any 2 sides of triangle is greater than the measure of third side , the value of k should be more than 7cm because if the value of k would be 7 , then 5 + 7 = 12 and the sum will get equal to the measure of longest side , hence such triangle wont exist.
Atlast , the range of k is :-
[tex]7 < k < 17[/tex]
