Samantha says the fraction of the group of customers who ordered raspberry topping is 1/2. Explain why samantha is correct.
Answer and explanation:
Yes Samantha is correct. Samantha is correct because a fraction 1/2 of customers who ordered raspberry toppings refers to half of the total number of customers. A fraction 1/2 is 50 percent or 50/100 of the population of customers, therefore meaning that 50% or half of the total number of group of customers ordered raspberry toppings
It is recommended that backpackers should carry no more than 20% of their body weight on long hikes and no more than 10% of their body weight on short hikes.
Part A
A hiker who weighs 160 pounds is planning a long hike. The weight of their backpack when packed with essential equipment is 15 pounds. Write an inequality to show how many pounds, p, the hiker can still add to their backpack and stay within the recommended weight.
Part B
A hiker who weighs 180 pounds is planning a day hike. The weight of their backpack when packed with essential equipment is 7.5 pounds. How much weight can the hiker still add to their backpack and stay within the recommended weight?
Place an X in the table to show whether each weight is within recommendation or not.
Answer:
10= hikers 160= pounds carried in items or gear X divided by P = amount of pounds of items each hiker carries.
x=10 P=160
Step-by-step explanation:
i cant see part B
Expressions can be represented as equations or inequalities
The inequality that represents the additional weight is: [tex]\mathbf{p \le 17}[/tex]The hiker can add additional 19.5 pounds(a) Long hike
The hiker's weight is given as:
[tex]\mathbf{Weight =160}[/tex]
The hiker is embarking on a long hike, the recommended weight (x) of the backpack is calculated as:
[tex]\mathbf{x = 20\% \times 160}[/tex]
[tex]\mathbf{x = 32}[/tex]
The hiker's backpack weighs 15 lb.
So, the inequality that represents the additional weight is:
[tex]\mathbf{p + 15 \le 32}[/tex]
Subtract 15 from both sides
[tex]\mathbf{p \le 32 - 15}[/tex]
[tex]\mathbf{p \le 17}[/tex]
(b) Day hike
The hiker's weight is given as:
[tex]\mathbf{Weight =180}[/tex]
The hiker is embarking on a day hike (i.e. short hike), the recommended weight (x) is calculated as:
[tex]\mathbf{x = 15\% \times 180}[/tex]
[tex]\mathbf{x = 27}[/tex]
The hiker's backpack weighs 7.5 lb.
So, the additional weight the hiker can add is represented as:
[tex]\mathbf{p + 7.5 = 27}[/tex]
Subtract 7.5 from both sides
[tex]\mathbf{p = 27 - 7.5}[/tex]
[tex]\mathbf{p = 19.5}[/tex]
Hence, the hiker can add additional 19.5 pounds

FYI - the length of the mid-segment of a trapezoid is equal to half the sum of the lengths of its bases.
the equation:
18 + 6x - 12 = 2(2x + 10)
18 + 6x - 12 = 4x + 20
6 + 6x = 4x + 20
6x = 4x + 14
2x = 14

1. Write a system of equations to describe the situation. Then solve the system. Be sure to define your variables! Rizzo has $1.50 less in his piggy bank than his sister Shonda. If Shonda had $9 more, she would have three times as much money as Rizzo. How much money do each of the children have in their banks?
Answer:
The amount Rizzo has = x = $5.25
The amount Shonda has = y = $6.75
Step-by-step explanation:
Let us represent:
The amount Rizzo has = x
The amount Shonda has = y
Rizzo has $1.50 less in his piggy bank than his sister Shonda.
x = y - 1.50.......Equation 1
If Shonda had $9 more, she would have three times as much money as Rizzo.
y + 9 = 3(x)
y + 9 = 3x..... Equation 2
y = 3x - 9
We substitute 3x - 9 for y in Equation 1
x = y - 1.50.......Equation 1
x = 3x - 9 - 1.50
9 + 1.50 = 3x - x
10.50 = 2x
x = 10.50/2
x = $5.25
Solving for y
y = 3x - 9
y = 3(5.25) - 9
y = $6.75
Therefore:
The amount Rizzo has = x = $5.25
The amount Shonda has = y = $6.75
A map has the scale 2 inches equals 190 miles. The distance from Springfield to Glenview is 14 inches. How many actual miles separate Springfield from Glenview?
A.
140
B.
2,800
C.
1,330
D.
38
Answer:
It would be C because
Step-by-step explanation:
2= 190
So what i did was i divide 190 to 2 and i got 95
and to the 14 I multiply it o 95 and i got 1,330
How i got 1,330 is that i read the question and looked at the answers which is a bigger number. So i thought it ain't adding or subtracting. So i decided to do dividing 190/2= 95 then i multiplied 14 to 95

arc AB = 12.4 cm
Step-by-step explanation:
The length of arc AB is 1/4 of the circumference of the circle, so is ...
AB = (1/4)(2πr)
= (π/2)r = (3.14/2)(7.9 cm) = 12.403 cm
Rounded to the nearest tenth, arc AB = 12.4 cm.

Ms Jackson want to rent an oversize truck for a week. It will cost a weekly fee plus $0.90 per mile driven. Let m= the number of miles Me Jackson drives during the week.
Answer:
Step-by-step explanation:
In order to calculate the total amount that Ms. Jackson will need to pay for renting we need to multiply the number of miles that she will drive by the price per mile driven. Once we have that product we can simply add the weekly fee (w) to it which will give us the total (T) amount that Ms. Jackson will have to pay for her trip. This can all be combined into the following formula.
T = w + 0.90m
