Answer:
(b) x > 26 cookies
Step-by-step explanation:
The selling price of 1 super-sized cookie, S.P.=$1.50
Let a batch have x cookies.
So, the selling price of x cookies=1.5x
The expences in making one batch of cookies=$10
So, net profit = 1.5x-10
The given inequality to model this is 1.5x - 10 > y, That means the profit for one batch is greater than y.
As she wants to make a profit of at least $30, so for this condition, the value of y is 30.
Now, the given inequality become,
[tex]1.5x - 10 >30[/tex]
[tex]\Rightarrow 1.5x>30+10[/tex]
[tex]\Rightarrow x>\frac{40}{1.5}[/tex]
[tex]\Rightarrow x>26\frac{2}{3}[/tex]
As x is the number of cookies, so, it can't have a fractional value. This can be written as
[tex]x>26[/tex] or [tex]x\geq27.[/tex]
So, she has to sell more than 26 cookies to make a profit of at least $30.
Hence, option (b) is correct.
is the fraction 11/20 a repeting and termnating decimal?
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.
Hope this helps.
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 .
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.

An object is traveling at a steady speed of 10 1/10 km/h. How long will it take the object to travel 1 9/10 km?
Answer:
It will take [tex]\frac{19}{101}[/tex] hour.
Step-by-step explanation:
The rule of the distance is:
Distance = speed × time
∵ An object is traveling at a steady speed of [tex]10\frac{1}{10}[/tex] km/h
∴ The speed = [tex]10\frac{1}{10}[/tex] km/h
∵ The object will travel [tex]1\frac{9}{10}[/tex] km
∴ The distance = [tex]1\frac{9}{10}[/tex] km
→ We need to find how long will it take it to travel this distance
→ Substitute the values of distance and speed in the rule above
∵ [tex]1\frac{9}{10}[/tex] = [tex]10\frac{1}{10}[/tex] × time
→ To find the time divide both sides by [tex]10\frac{1}{10}[/tex]
∴ The time = [tex]1\frac{9}{10}[/tex] ÷ [tex]10\frac{1}{10}[/tex]
→ Change the mixed numbers to an improper fraction
∵ [tex]1\frac{9}{10}[/tex] = [tex]\frac{(1)(10)+9}{10}=\frac{19}{10}[/tex]
∵ [tex]10\frac{1}{10}=\frac{(10)(10)+1}{10}=\frac{101}{10}[/tex]
∴ The time = [tex]\frac{19}{10}[/tex] ÷ [tex]\frac{101}{10}[/tex]
- Reverse the fraction after the division sign, then change ÷ to ×
∴ The time = [tex]\frac{19}{10}[/tex] × [tex]\frac{10}{101}[/tex]
→ 10 up will cancel 10 down
∴ The time = [tex]\frac{19}{101}[/tex] h
It will take [tex]\frac{19}{101}[/tex] hour.

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?
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

5 2/3 gave to her 4 friends how much did each one receive
Answer:
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 .
_________________________________

If it is 5 × 2/3

_________________________________
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{10}{3} \div 4 = \frac{10}{3} \times \frac{1}{4} = \frac{10}{12} \\ [/tex]
So each of her friends receive 10/12 .

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?
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

The length of a rectangle is (x-8) units, and its width is(x+11) units. What is an expression for this.
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
