Which choices are equivalent to the fraction below? Check all that apply. 16\20
Answer:
To write 16.20 as a fraction you have to write 16.20 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number. 16.20 = 16.20/1 = 162/10 And finally we have:

happening to the temperature?
Answer:
Step-by-step explanation:
The temperature starts at 50 and increases because the slope is positive.
Anthony scored 28 points in a recent basketball game. He made a total of 12 baskets. How many 2 and 3 point shots did he make? (Consider only the 2 and 3 point shots: no free throws)
Answer:
8 2-point shots and 4 3-point shots
Step-by-step explanation:
Anthony scored 28 points with 12 baskets. Saying that, (with x-y representing 2 point shots-3 point shots) any combination with a supermajority (at least 75% of) of either shot is out. This leaves just 5 possible combinations. 8-4, 7-5, 6-6, 5-7, and 4-8. Multiply the first number by 2 and the second by 3.
(4 * 2) + (8 * 3) = 8 + 24 = 32 points, so no.
(5 * 2) + (7 * 3) = 10 + 21 = 31 points, so no.
(6 * 2) + (6 * 3) = 12 + 18 = 30 points, so no.
(7 * 2) + (5 * 3) = 14 + 15 = 29 points, so no as well.
(8 * 2) + (4 * 3) = 16 + 12 = 28 points, so this is the combination we're looking for.

The graph shows the linear relationship between the total sales and the amount of items purchased from the local Dollar Store
Which equation best represents the relationship shown in the graph?
Answer:
A. Y= 2x+1
Step-by-step explanation:
The reason for this is if you use the formula Y=Mx+ b it will help you solve this question so lets say you take the points (3,1) Where the 3 is the Y value and the 1 is the X value, so now you would show your work starting by labeling the (3,1) points and label them as their value, then write your formula Y=Mx+ b and then replace those values as 3=2(1)+1 and that equals 3.
Daniel read 1/3 of a book in the morning, and he read some more at night. By the end of the day, he still had 2/5 of the book left to read. How much of the book did Daniel read at night?
Answer:amount read at night =4/15
Step-by-step explanation:
Step 1
Since we are dealing with fractions,
Let Total amount of book contained to read = 1 whole
Therefore
Amount read in the morning + amount read at night +amount remaining = Total amount of book contained to read which gves us the equation
1/3 + x + 2/5 = 1
Step 2 --- solving
1/3 + x + 2/5 = 1
1/3 + 2/5 + x= 1
5 + 6 / 15 + x = 1
11/15 + x= 1
x= 1 - 11/15
15/15 - 11/15
x = amount read at night =4/15

A cylinder has a diameter of 7 and height of 10.4 . What is its total surface area to two decimal places
Answer:
305.68
Step-by-step explanation:
π = 3.14(aka pi)
d=diameter
h=height
^=exponent
The formula for doing this types of problem is 2π d/2h + 2π(d/2)^2. So all you do is fill in the diameter and height of the variable.
2π 7/2(10.4) + 2π(7/2)^2=305.68

2) translation: 1 unit right and 2 units down
The function g(x) is a translation of f(x) = (x + 3)2 – 10. The axis of symmetry of g(x) is 5 units to the right of f(x) . Which function could be g(x)?
Answer:
There are two possible solutions for [tex]g(x)[/tex]:
[tex]g(x) = (x+3)^{2}-5[/tex]
[tex]g(x) = x^{2}-3\cdot x +4[/tex]
Step-by-step explanation:
From statement, we understand that [tex]g(x)[/tex] is defined by the following operation:
[tex]g(x) = f(x) +5[/tex] (1)
If we know that [tex]f(x) = (x+3)^{2}-10[/tex], then [tex]g(x)[/tex] is defined by:
[tex]g(x) = (x+3)^{2}-10+5[/tex]
[tex]g(x) = (x+3)^{2}-5[/tex]
[tex]g(x) = x^{2}-3\cdot x + 9 -5[/tex]
[tex]g(x) = x^{2}-3\cdot x +4[/tex]

John hit a golf ball from the ground and it followed the projectile h(t)=-16t²+100t+0, where is the time in seconds, and ℎ is the height of the ball. Use the quadratic formula to solve the two roots. These represent the 2 times that the ball is on the ground. At what time does the golf ball land? What is the max height of the golf ball? At what time (t) is the golf ball at the maximum height?
Answer:
The maximum height of the golf ball h(t) = 156.25m
The maximum height of the golf ball at t = 3.125 seconds
Step-by-step explanation:
Step(i):-
Given
h(t)=-16t²+100t ...(i)
Differentiating equation (i) with respective to 't'
[tex]\frac{dh}{dt} = -16(2t) + 100 (1)[/tex]
-32t + 100 =0
⇒ -32 t = -100
[tex]t = \frac{100}{32} = \frac{25}{8} = 3.125[/tex]
t = 3.125 > 0
Step(ii):-
Given h(t) = -16t²+100t = 0
t ( -16 t + 100 ) =0
t =0 and -16t = -100
t =0 and t = 6.25
Step(iii):-
h(t) = -16t²+100t ...(i)
put t=0 in equation (i)
h(0) = 0
put t = 3.125 in equation (i)
h(t) = -16(3.125)²+100(3.125)
h (t) = 156.25
Put t = 6.25
h(t) = -16(6.25)²+100(6.25)
= 0
The maximum value h(t) = 156.25 at 3.125
final answer:-
The maximum height of the golf ball h(t) = 156.25m
The maximum height of the golf ball at t = 3.125 seconds

The scale on a road map indicates that 2 inches = 30 miles. How many inches would represent 120 miles on this road map?
Answer:
8 inches = 120 miles
Step-by-step explanation:
If 2 inches is equivalent to 30 miles, then divide 120 by 30 then times the answer by two.
120 / 30 = 4
4 x 2 = 8
8 inches = 120 miles
To check;
30 x 4 = 120
8 / 2 = 4

Describe the error in determining whether the lines are parallel, perpendicular, or neither.
Step-by-step explanation:
The slopes of perpindicular lines must be negative reciprocals of each other -- while -4 and 4 are negative to each other, the negative recipricocal for -4 is 1/4 and -1/4 for 4.
The slopes of parallel lines must be the same, so these are not parallel.
