Mark used a number line to model dividing by 3. He
divided the number line from 0 to 1 in 3 equal sections,
and then divided each of those sections into 2 equal
parts. Mark says § + 3 is į
Is his answer correct? Explain why or why not.
PLS ANYBODY HELP ME ON THIS 20 points
Answers
Answer: No, he is incorrect
Step-by-step explanation:
No, he is incorrect. Using a number line to model thirds means that each space that is 1/3 should be divided into 3 parts, not 2 parts. 6 parts divided into 3 groups gives 2 parts out of 9 parts total, so the answer is 2/9.

x = 0 and x = -3
x = 10 and x = -8
Answers
Answer:
x = 0 and x = 1
Step-by-step explanation:
From the table of values
f(x) = g(x) = 1 when x = 0 , and
f(x) = g(x) = 0.25 when x = 1
The solution to f(x) = g(x) are x = 0 and x = 1

Let's see what to do buddy...
Step-by-step explanation:
If it is 5 + 2/3
_________________________________
Step (1)
First we have to find all she has :
[tex]5 \frac{2}{3} = 5 + \frac{2}{3} = \frac{5 \times 3}{3} + \frac{2}{3} = \\ \frac{15}{3} + \frac{2}{3} = \frac{17}{3} [/tex]
_________________________________
Step (2)
To find how much did each of them receive , we must divided all by the number of her friends which is 4.
So we have :
[tex] \frac{17}{3} \div 4 = \frac{17}{3} \times \frac{1}{4} = \frac{17}{12} \\ [/tex]
So each of her friends receive 17/12 .

Step (2)
To find how much did each of them receive , we must divided all by the number of her friends which is 4.
So we have :

So each of her friends receive 10/12 .

A student in the Construction Trades program at the Cecil County School of Technology has 4 1/2gallons of paint. If he uses 2.75 gallons of the paint in one room, how many gallons of paint are left? Show your work on your paper and write your final equation and correct answer in the box below.
Answers
Answer:
1.75 gallons of paint
Step-by-step explanation:
A student in the construction trades program has 4 1/2 gallons of paint
If the student uses 2.75 gallons in one room then the gallons of paint that are left can be calculated as follows
= 4 1/2 - 2.75
= 9/2 - 2.75
= 4.5 - 2.75
= 1.75
Hence 1.75 gallons of paint are left

is the fraction 11/20 a repeting and termnating decimal?
Answers
Answer:
it is terminating
Step-by-step explanation:
Answer:
11/20 is a terminating decimal.
Step-by-step explanation:
1) Find the denominator of 11/20 in its lowest form.
The greatest common factor (GCF) of 11 and 20 is 1. Convert 11/20 to its simplest form by dividing the numerator and denominator by its GCF: The denominator of 11/20 in its lowest form is 20.
11 ÷ 1 / 20 ÷ 1 = 11 / 20
2) Find the prime factors of the answer in Step 1.
The prime factors of 20 are all the prime numbers that you multiply together to get 20. The prime factors of 20 are:
2 x 2 x 5
3) Determine if 11/20 is terminating.
A fraction is a terminating decimal if the prime factors of the denominator of the fraction in its lowest form only contain 2s and/or 5s or no prime factors at all. This is the case here, which means that our answer is as follows:
11/20 = terminating.

The length of a rectangle is (x-8) units, and its width is(x+11) units. What is an expression for this.
Answers
Answer:
(x²+3x-88) square units
Step-by-step explanation:
Area of a rectangle = Length × Width
Given
length of a rectangle is (x-8)units
Its width is (x+11) units.
Required
Expression for the area of the rectangle
Substituting the given function into the formula.
Area of the rectangle = (x-8)(x+11)
Area of the rectangle = x(x)+11x-8x-88
Area of the rectangle = x²+3x-88
Hence the expression that represents the area of the rectangle is x²+3x-88 units²

Jeremiah has $7 to spend at the school store. He definitely wants to buy a Sprite for $1.50 and wants to use the rest of his money to buy as many packs of gummy worms as possible. If the gummy worms are on sale for $0.27 each, how many packs can Jeremiah buy?
Answers
Answer:
Step-by-step explanation:
Amount with Jeremiah = $7
Cost of Sprite = $1.50
Amount remaining = Amount with Jeremiah - Cost of Sprite
= $7 - $1.50
= $5.50
Gummy worms cost = $0.27 each
Number of gummy worms he can purchase = $5.50 / $0.27
= 20.37
Jeremiah can buy as many as 20 packs of gummy worms

You start driving from Austin to Houston with a constant speed of 120km/hr (75 mph). After 1.5 hr you stop for 0.5 hr. Then you continue driving with a new constant speed v2 and reach Houston 45 mins later. If the total distance from Austin to Houston is 265km, what is the speed v2?
Answers
Answer:
113.33 km/hr
Step-by-step explanation:
Given that :
From Austin
Drive 1 : Speed of 120km/hr for 1.5 hours
Stop time = 0.5 hour
Drive 2 : speed of v2 for 45 minutes to finally reach Houston
Total distance (Austin to Houston) = 265 km
Total distance : (distance on drive + distance on second drive)
Distance = speed * time
(120 * 1.5) + (v2 * 45/60) = 265
180 + 0.75v2 = 265
0.75v2 = 265 - 180
0.75v2 = 85
v2 = 85 / 0.75
v2 = 113.33km/hr
v2 = 85 / 0.75
v2 =

Line PQ is located in the coordinate plane with point P at(-2,-2)

(5,9)
(9,5)
(5. – 1)
(1-1,5)
Answers
Answer:
The coordinates of point S are (5, 9) will make line PQ // line RS ⇒ A
Step-by-step explanation:
Parallel lines have the same slopes
The slope of a line = Δy/Δx, where
Δ y is the change of yΔ x the change of xLet us first find the slope of the line PQ.
∵ P = (-2, -2) and Q = (0, 7)
∴ Δx = 0 - (-2) = 0 + 2 = 2
∴ Δy = 7 - (-2) = 7 + 2 = 9
∴ The slope of PQ = 9/2
∵ Line PQ // line RS
∴ The slope of line PQ = the slope of line RS
∴ The slope of line RS =9/2
∵ Point R = (3, 0) and point S = (x, y)
∵ The slope of line RS = 9/2
∵ The slope = Δy/Δx
∴ Δy/Δx = 9/2
→ That means Δy = 9 and Δx = 2
∵ Δy = y - 0
∵ Δy = 9
∴ 9 = y
∵ Δx = x - 3
∵ Δx = 2
∴ 2 = x - 3
→ Add 3 to both sides
∴ 2 + 3 = x - 3 + 3
∴ 5 = x
∴ The coordinates of point S are (5, 9) will make line PQ // line RS

At an important meet, Rosalva won the women’s 100 meters in 13.47 seconds. Rosalba ran at an average rate of _ meters per second .
Answers
Answer:
about 7.42 meters per second
Step-by-step explanation:
speed = distance/time
Rosalba moved at a speed of 7.27 meters per second on average.
What is Speed?speed is described as. the pace at which an object's location changes in any direction. Speed is defined as the distance traveled divided by the travel time. Speed is a scalar quantity because it just has a direction and no magnitude.
Given, At an important meet, Rosalva won the women’s 100 meters in 13.47 seconds.
From the general formula of speed:
Speed = distance/time
In our case,
Distance= 100 meters
time = 13.74
Thus,
Speed = 100/ 13.74
Speed in meters per second = 7.27
therefore, Rosalba ran at an average rate of 7.27 meters per second.
