Answer:
Number of books with Mrs. Hall = 32
Step-by-step explanation:
Suppose that Mrs. Hill has [tex]x[/tex] books.
Also, Mr. Lopez has 24 more books than Mrs. Hill.
So,
Number of books with Mr. Lopez = [tex]x+24[/tex]
Ratio of their books = [tex]7:4[/tex]
Therefore,
[tex]\frac{x+24}{x}=\frac{7}{4}\\\\4(x+24)=7x\\\\4x+96=7x\\\\96=3x\\x=\frac{96}{3}\\\\x=32[/tex]
Number of books with Mrs. Hall = 32

Answer:
5 and 10
Step-by-step explanation:
You have all the information you need to find the area of the circle and then subtracting that from 77 you'll have the area of the rectangle and will be able to figure out the length and height by looking at the answer options.
So the area of a triangle is 1/2(b x h) or (b x h)/2 so the base is 6 and the height is 9 so the area is 54/2 which equals 27. 77 - 27 = 50 so the area of the rectangle is 50. With the answer options provided I can see that the height of the rectangle is 5 and the length is 10.
Kara bought a gift for her nephew. She spent $25 on the gift. Sales tax was 6.75%. What was the total cost for the gift , including tax?
To find total price multiply the cost of the item by 1 + tax rate.
25 x 1+6.75% = 25 x 1.0675 = 26.69

HELP PLZ AGAIN. Same material. It is still timed. Will give 50 pts and brainly. This is vital to my math grade. Time is on the essence and my math grade is at stake if I do not pass this. I need Slope Intercept form for the equation. HELP HELP HELP PLZ.
Answer:
y = 4x - 9
Step-by-step explanation:
y = 4x + 2
the the slope m is 4
the new line which paraller to the first one will have a slope 4 too
M = 4
then, the new slope-intercept form which pass through (x1,y1), in this case (5,-4) is
y - y1 = M(x - x1)
y - (-4) = 4(x - 5)
y + 4 = 4x - 5
y = 4x - 5 - 4
y = 4x - 9
Answer:
Step-by-step explanation:
FYI only
Slopes of parallel lines are the same and y-intercepts are different
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
y - [tex]y_{1}[/tex] = 4( x - [tex]x_{1}[/tex] )

Alright fam, help me out here with these angles thanks!
Answer:
m∠3 = 127°
Step-by-step explanation:
From the given picture,
Two parallel lines have been given.
Angle 3 and another angle measuring 53° are located on a point of a straight line.
Therefore, both the angles will be supplementary.
m(∠3) + 53° = 180° [Property of supplementary angles]
m(∠3) = 180° - 53°
= 127°

Quadrilateral BCDE is inscribed in circle A. ∠ and ∠ measure 70.85° and 78.03°, respectively.
Determine the measure of ∠ .
Answer:
∠ DEB = 101.97°
Step-by-step explanation:
BCDE is a cyclic quadrilateral, whose opposite angles are supplementary, so
∠ BCD + ∠ DEB = 180°, that is
78.03° + ∠ DEB = 180° ( subtract 78.03° from both sides )
∠ DEB = 101.97°

If x=2,find the value of x²+1/x²
Answer:
17/4 or 4 1/4
Step-by-step explanation:
Substitute x = 2 into the expression x² + 1/x².
(2)² + 1/(2)²Evaluate the exponents in the expression.
(4) + 1/(4) 4 + 1/4Multiply 4 by 4/4 to get a common denominator of 4.
16/4 + 1/4Add the numerators together.
17/4The value of x² + 1/x² if x = 2 is 17/4, or 4 1/4.

Which expression in equivalent to 48x-6+3y/3
Answer:
48x-6+y
Step-by-step explanation:
The expression that should be equivalent to the given expression is to be considered as the 16x - 2 + y.
Calculation of an expression:Since the equation is [tex]48x-6+3y\div 3[/tex]
We have to divide by whole equation by 3
After dividing it, the expression should be like 16x - 2 + y.
Hence, The expression that should be equivalent to the given expression is to be considered as the 16x - 2 + y.

Arectangle has a width that is 8 centimeters less than its length. The perimeter of the rectangle is 56 centimeters. Find both the width and length of the rectangle. Show your work.
Answer:
L=18cm
W=10cm
Step-by-step explanation:
Given data
let the length be x
L=x
Width= x-8
W= x-8
Perimeter= 56cm
But we know that the perimeter is expressed as
P=2L+2W
substitute our data
56=2(x)+2(x-8)
56=2x+2x-16
56+16=4x
72=4x
divide both sides by 4
x= 72/4
x=18cm
Hence the Length is 18cm
L=18cm
The width= 18-8
W=10cm

I'd appreciate any help I can get! :) A gold statue has a diameter of 60 inches and a height of 80 inches. It has a total volume of 320 inches cubed. The replica is proportional to the statue. The replica's height is 100 inches. What is the replica's volume?
Answer:
Volume of replica = 625 cubic inches
Step-by-step explanation:
Height of the gold statue = 80 inches
Volume of the gold statue = 320 cubic inches
Height of the replica = 100 inches
Dimensional scale factor = [tex](\frac{\text{Dimension of the replica}}{\text{Dimension of the original statue}})[/tex]
= [tex]\frac{100}{80}[/tex]
= 1.25
Volume scale factor = [tex]\frac{\text{Volume of replica}}{\text{Volume of original}}[/tex]
Since, volume scale factor = (Dimensional scale factor)³
[tex]\frac{\text{Volume of replica}}{\text{Volume of original}}=(1.25)^3[/tex]
Volume of replica = (1.25)³ × Volume of original statue
= (1.25)³ × 320
= 625 cubic inches
One side of a triangle is 7 and another side is 10. Which of the values below could
be the third side of the triangle?
x is the third side of the triangle, we have:
7 + 10 > x > 10 - 7
<=> 3 < x < 17
so the answer is C. III and IV only
Answer:
C
Step-by-step explanation:
given 2 sides of a triangle, then the third side, x , is in the range
difference of 2 sides < x < sum of 2 sides , that is
10 - 7 < x < 10 + 7
3 < x < 17
The only values in the list between 3 and 17 are 4 and 16.
That is III and IV only → C
