There are 6 bookshelf's that hold 72 books per shelf. if 1/3 of the total number of books are non-fiction,how many fiction books are there.
Answers
Answer:
288 fiction books
Step-by-step explanation:
If the other 2/3 are fiction, then I believe that you would multiply 72 by 6 then divide by 3 or multiply by 1/3 giving you 144. Multiply 144 by 2 and you should get 288, but this is if there are only fiction and non fiction. Sorry if this is wrong..

Mathius walked ⅜ mile to school. Eva walked ⅖ mile to school. How many more
feet did Eva walk to school than Mathius? (1 mile = 5,280 feet). Explain how you
determined your answer using words and numbers.
Answers
Answer:
132ft
Step-by-step explanation:
Mathius Distance = 3/8 mile
Eva Distance = 2/5 mile
1 mile = 5,280ft
1. Start by multiplying the mile distance of Mathius to the distance of 1 mile in feet.
5,280ft x 3/8 = 15840ft/8 = 1980ft
2. Do the same thing as number 1 but for Eva's distance now.
5,280ft x 2/5 = 10560ft/5 = 2112ft
3. Subtract Eva's Distance from Mathius' Distance for the answer.
2112ft (Eva) - 1980ft (Mathius) = 132ft

greater than - 10 times the third integer.
Answers
Answer:
-4, -2, 0 or -8, -6, -4
Step-by-step explanation:
#1 =x
#2 = x+2
#3 = x+4
x(x+2) = -10(x+4) + 8
x^2 + 2x = -10x - 40 + 8
x^2 + 12x + 32 = 0
(x+8)(x+4) = 0
x = -8 or x = -4 so:
#1 = -8 or -4
#2 = -6 or -2
#3 = -4 or 0

Age If you add Natalie's age and Fred's age, the result is 43. If you add Fred's age to 4 times
Natalie's age, the result is 79. Write and solve a system of equations to find how old Fred and
Natalie are.
Fred is
years old. Natalie is
years old.
Answers
So,
A/Q
X + Y = 43. Let it be eqution 1
and
X + 4Y = 79. Let it be equation 2
Combining equation 1 and 2, we get
( X + Y) + 3Y = 79
43 + 3Y = 79
3Y = 36
Y = 12
Now, evaluating the value of Y in equation 1 we get,
X + 12 = 43
X = 31
Therefore, Fred is 31years old and Natalie is 12 years old.

In the triangle above, the console of p degrees is 0.8 what is the sine of q degrees
Answers
Answer:
Step-by-step explanation:
[tex]cosp=(8/10)\\ \\ p=cos^{-1}(8/10)\\ \\ q=90-p\\ \\ q=90-cos^{-1}(8/10)\\ \\ sinq=sin(90-cos^{-1}(8/10)\\ \\ sinq=(8/10)[/tex]
In the triangle above, the console of p degrees is 0.8. So, the sine of angle q is 0.6.
It seems like there is a description of a triangle with angles p and q, where the console of angle p is 0.8. However, the term "console" is not familiar in the context of trigonometry. I assume you meant "cosine" instead of "console."
If that's the case, let's proceed with the assumption that cos(p) = 0.8.
The cosine of an angle is the ratio of the adjacent side to the hypotenuse in a right-angled triangle. To find the sine of angle q, we need to use the Pythagorean trigonometric identity:
sin²(q) + cos²(q) = 1
We already know that cos(p) = 0.8, and since the sum of angles in a triangle is 180 degrees, we can find q:
q = 180 - p
Now, let's calculate sin(q):
sin²(q) + cos²(q) = 1
sin²(q) + (0.8)² = 1
sin²(q) = 1 - 0.64
sin²(q) = 0.36
Now, take the square root of both sides to find sin(q):
sin(q) = √0.36
sin(q) = 0.6
So, the sine of angle q is 0.6.

A cup of coffee contains 140 mg of caffeine. If caffeine leaves the body at 10% per hour, how long will it
take for half of the caffeine to be eliminated from one's body?
Answers
Answer: 5 hours
Step-by-step explanation:
If 10% of 140 is 14. And if 14 mg of caffeine is leaving per hour then it would take 10 hours to completely leave from ones body, but for half of it to leave it would take 5.
It takes 5 hours to eliminate half of the caffeine from one's body.
Given that, a cup of coffee contains 140 mg of caffeine.
What is the percentage?In mathematics, a percentage is a number or ratio expressed as a fraction of 100.
Now, 10% of 140
=0.1×140=14 mg
If 10% of 140 is 14 and if 14 mg of caffeine is leaving per hour then it would take 10 hours to completely leave from one's body, but for half of it to leave it would take 5 hours.
Therefore, it takes 5 hours to eliminate half of the caffeine from one's body.

Use the drop-down menus to describe the horizontal translation used.
Answers
Answer:
Quadrilateral WXYZ is translated 10 units to the left
Step-by-step explanation:
Translation of Shapes in the Plane
The translation is a type of rigid transformation where all the coordinates of the vertices that form the shape are shifted by the same number of units both vertically and horizontally.
The quadrilateral WXYZ has coordinates:
W(2,-3) X(7,-3) Y(6,-7) Z(1,-7)
The quadrilateral W'X'Y'Z' has coordinates:
W'(-8,-3) X'(-3,-3) Y'(-4,-7) Z'(-9,-7)
It can be noted that all the x-coordinates of the vertices are shifted by 10 units to the left.
Answer:
Quadrilateral WXYZ is translated 10 units to the left.

What is dilation of triangle?Dilation of triangle means each point is stretched outwards or inwards from the center point by multiplying by the scale factor to form a similar triangle.
We have,
Triangle [tex]T V W[/tex] which has points [tex](- 4, 8)[/tex], [tex](0, 4)[/tex], and [tex](4, 4)[/tex] on a coordinate plane.
Scale factor [tex]\frac{3}{4} x, \ \frac{3}{4} y[/tex]
It has to be dilated to create a new triangle [tex]T'V'W'[/tex] .
So,
To create a new triangle [tex]T'V'W'[/tex] we have to multiply the original triangle's coordinate by scale factor, to get new triangle's coordinate .
So, we have to dilate the coordinates by [tex]\frac{3}{4} x, \ \frac{3}{4} y[/tex] ,
[tex]T'=(- 4, 8)=\frac{3}{4} *(-)4, \frac{3}{4} *8= (-3,6)[/tex]
[tex]V'=(0, 4)=\frac{3}{4} *0, \frac{3}{4} *4=(0,1)[/tex]
[tex]W'=(4, 4)=\frac{3}{4} *4,\frac{3}{4} *4=(0,0)[/tex]
So, the coordinates of triangle [tex]T'V'W'[/tex] after dilation are [tex](-3,6), \ (0,1), \ (0,0)[/tex] . Hence we can say that the coordinates of the endpoints of the segment [tex]T'V'[/tex] are [tex](-3,6), \ (0,1).[/tex]

Answer:
A: E = 0.05t +56
B: $73.50
C: $60.05
Step-by-step explanation:
A) I'll just explain the equation in one go
Equation: E = 0.05t + 56
0.05 - This is meant to represent the 5% of tips
5% = 5/100
5/100 = 0.05
56 - This is a set value that has been established as a constant, thus it simply needs to be added to the 5%
B+C) Since we already have the equation set up, we just need to plug in the variable, t.
B) E = 0.05(350) + 56
= 17.5 + 56
= 73.50
C) E = 0.05(81) + 56
= 4.05 + 56
= 60.05
