Each friend needs to collect $37.50 to reach the goal.
To find out how much money each friend needs to collect, Andrea followed these steps:
Andrea understood that there are four friends collecting money for dog food, which costs $150 in total.
Andrea decided to divide the total cost of dog food by the number of friends to find out how much each friend needs to collect.
Andrea divided the total cost ($150) by the number of friends (4):
$150 ÷ 4 = $37.50
Check: Andrea made sure her answer makes sense. Each friend will contribute $37.50, and since there are four friends, the total collected would be:
$37.50 × 4 = $150
The total collected indeed matches the cost of dog food.
Reflect: Andrea confirmed that each friend needs to collect $37.50.
Therefore, each friend needs to collect $37.50 to reach the goal.
What type of triangle has the sides 3 16 and 17?
a piece of yellow yarn was 230 inches long. After 90 inches had een cut from it,,, the piece of yellow yarn was twice as longas a piece of blue yarn. How much longer than the blue yarn was the yellow yarn at first?
Answer:
160 inches longer.
Step-by-step explanation:
Let x represent the length of the blue yarn.
We have been given that a piece of yellow yarn was 230 inches long. After 90 inches had been cut from it, the piece of yellow yarn was twice as long as a piece of blue yarn.
Twice the length of blue yarn would be [tex]2x[/tex].
We can represent this information in an equation as:
[tex]2x+90=230[/tex]
[tex]2x+90-90=230-90[/tex]
[tex]2x=140[/tex]
[tex]\frac{2x}{2}=\frac{140}{2}[/tex]
[tex]x=70[/tex]
Therefore, the length of blue yarn is 70 inches long.
Now, we will subtract 70 from 230 as:
[tex]230-70=160[/tex]
Therefore, the yellow yarn was 160 inches longer than the blue yarn.
The equation d=rt is used to calculate distance, rate, or time, where dd is the distance (in meters), r is the rate (in meters per minute), and tt is the time (in minutes). Consider the statements below that describe the walking rates for three people. Graph the equation that represents the rate of the fastest person. Tomas walks 1200 meters in 8 minutes. Becky walks for 10 minutes and goes 1400 meters. Derrick walks at a rate of 145 meters per minute.
Tomas is the fastest walker so we will write the equation based on his speed.
What is speed?Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance. Speed is the ratio of the distance travelled by time. The unit of speed in miles per hour.
Given that the equation d=rt is used to calculate distance, rate, or time, where dd is the distance (in meters), r is the rate (in meters per minute), and t is the time (in minutes).
Tomas: 1200/8= 150 m/min
Becky: 1400/10= 140m/min
Tomas is the fastest walker so we will write the equation based on his speed
y = 150x

Bryan is buying notebooks and pens at an office supply store. Notebooks cost $3.59 and pens cost $1.49. He can spend up to $13 on these items. Let x represent the number of notebooks. Let y represent the number of pens. Enter an inequality that represents the situation. Please help!! :)
Answer:
3.59x + 1.49y ≤ 13
Step-by-step explanation:
Let x represents the number of notebooks and y represents the number of pens.
If notebooks cost $3.59 and pens cost $1.49 then total cost of the pens and notebooks will be = 3.59x + 1.49y
Bryan spends up to $13 means that total expenditure must be less than equal to $13
Then inequality will be
3.59x + 1.49y ≤ 13
The angles of a triangle are 2x, 3x, and 4x degrees.
Find the value of x.
A) 20
B) 30
C) 40
D) 50
3 angles in a triangle need to = 180 degrees
so you have 2x+3x+4x = 180
9x = 180
x = 180/9
x = 20
Answer is A

Bethany is baking cookies for her school's bake sale. She plans to bake more than 185 cookies, in batches of 12 cookies. So far, Bethany has baked a total of 48 cookies. What inequality describes this situation, if b represents the number of batches of cookies Bethany has left to bake?
The inequality that describes this situation is "b > 12", where b represents the number of batches of cookies Bethany has left to bake.
What is inequality?Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.
As per the question, we can start by subtracting the number of cookies that Bethany has already baked (48) from the total number of cookies she plans to bake (185).
This gives us a difference of 185 - 48 = 137 cookies.
Dividing this number by the number of cookies per batch, we get 137 / 12 = 11.41.
Since Bethany is baking whole batches of cookies, the number of batches she has left to bake must be at least 12.
This means b > 12
Therefore, the inequality "b > 12" accurately describes the situation, where b is the number of batches Bethany has left to bake.

It takes a bus driver 30 minutes to pick up students from four spots. The last stop is at the corner of Green Street and Route 70. The most direct route to school is north on Route 70. The speed limit on Route 70 is 35 kph. The bus driver wants to calculate the average velocity from the last stop to school. Can this be done from the information given?
A. Yes, if the speed limit is 35 kph, and the elapsed time is 30 minutes, the average velocity is 17.5 kph north.
B. No, the distance from the last stop to the school and the time is takes to travel that distance are required.
C. Yes, if the average speed is 35 kph, and it takes 30 minutes, the average velocity is 17.5 kph.
D. No, the distance from the first stop to the school and the average speed are required.
Answer:
B. No, the distance from the last stop to the school and the time is takes to travel that distance are required.Step-by-step explanation:
The problem doesn't give enough information to find the average velocity, because it doesn't specifies the total distance the driver has to cover, neither the time.
Also, the problem doesn't offer the initial or final speed of each part of the road, which can be used to find the average.
However, the best option to find the average velocity here is by knowing the total distance and the total time required, because their quotient is the average speed.
Therefore, the right answer is B.
