rate, which line on the graph below best represents the number of pages Larry can read
per minute?
You didn't include a picture of the graph, but Larry can read 6 pages of his book in a minute.

Answer: For 1, the answer is B since there is no rational number for sqrt17.
For 2, the answer is C since it has to be less than 11 whose square is 121 and larger than 10 whose squre is 100.
For 3 the answer is B. Just plug the x value into the equation. => y=1/2(-1)-2 => y= -1/2-2 => -2 1/2.

One interior angle of a triangle is 60'. The other angle measures are x' and y'. Which of the following could be the values of x
and y? Select all that apply.
A x = 50, y = 90
B. * = 100, y = 20
C. x = 45, y = 45
D. X = 40, y = 80
E. x = 60, y = 60
Answer:
B. x = 100, y = 20
D. X = 40, y = 80
E. x = 60, y = 60
Step-by-step explanation:
The sum of interior angles of a triangle = 180°
From the above question, one of the angles = 60°
The value for the two other interior angles = 180° - 60° = 120°
Hence, the following options could be the values of x and y is given as x + y = 120
Therefore,
B. x = 100, y = 20
D. X = 40, y = 80
E. x = 60, y = 60

In the diagram below of triangle ABC, medians AD, BE and CF intersect at point G
If the length of AD is 48 cm, how many centimeters long would DG be?
Answer:
DG = 16 cm
Step-by-step explanation:
DG is one- third of AD , then
DG = [tex]\frac{1}{3}[/tex] × 48 = 16
The length of the segment DG will be equal to 16 cm.
What is geometry?Geometry is one of the oldest branches of mathematics, along with arithmetic. It is concerned with spatial qualities such as figure distance, shape, size, and relative position. A geometer is a mathematician who works in the field of geometry.
Given In the diagram below of triangle ABC, medians AD, BE and CF intersect at point G and the length of AD is 48 cm.
The length of the segment DG will be calculated as,
DG is one-third of AD, then
DG = ( 1 / 3 ) × 48
DG = 16
Therefore, the length of the segment DG will be equal to 16 cm.

1. Find the volume of the cylinder to the nearest hundredth. Use the pi key for pi.
6 in
8 in
Answer:
diameter(d)=8 in.
radius(r)= d/2= 4 in.
height(h)= 3r = 3(4) = 12 in.
Volume=r ² h
=(3.14)(4)²(12)
=(3.14)(16)(12)
=602.88 in.
Therefore, the volume of the cylinder is 602.88 in.

⦁ Convert the vertex form of the equation you wrote above to standard form.
the vertex was ax+b(?)
Answer:
ax^2 + bx + c
Step-by-step explanation:
im pretty sure this answers your question
The standard form of the vertex form equation is y = 2x² - 12x + 17
How to convert the equation?The vertex form of a quadratic equation is represented as:
y = a(x - h)² + k
Using the above form, the quadratic equation can be represented as:
y = 2(x - 3)² + 1
Expand
y = 2(x² - 6x + 9) - 1
Further expand
y = 2x² - 12x + 18 - 1
Evaluate the like terms
y = 2x² - 12x + 17
Hence, the standard form of the vertex form equation is y = 2x² - 12x + 17

Ben bought 2 shirts for $16 each, 3 pairs of socks for $2.50 a pair, and a pair of jeans for $37.75. If the sales tax rate is 6.5%, how much did he pay for his items?
Answer:
Total amount pay by Ben = $82.27 (Approx.)
Step-by-step explanation:
Given:
2 Shirts = $16 each
3 pairs of socks = $2.50 each
1 pair of jeans = $37.75 each
Sales tax = 6.5%
Find:
Total amount pay by Ben
Computation:
Total amount for shirts = 2 x 16
Total amount for shirts = $32
Total amount for socks = 3 x 2.50
Total amount for shirts = $7.50
Total amount before tax = $32 + $7.50 + $37.75
Total amount before tax = $77.25
Total amount pay by Ben = Total amount before tax[1+tax]
Total amount pay by Ben = 77.25[1+6.5%]
Total amount pay by Ben = $82.27 (Approx.)
