Madison is buying bulky candy for a dance company fundraiser. She buys 1000 candy bars for $350. What is the unit cost per candy bar?(1 point) Responses $0.30 $0.30 $0.35 $0.35 $3.50 $3.50 $3.00
To find the unit cost per candy bar, divide the total cost by the number of candy bars: $350 / 1000 = $0.35.
So the correct answer is $0.35.
A hiker ascended 3/4 of a kilometer in 1/16 of an hour. What was the mountain hiker's ascent rate in kilometers per hour (kph)?(1 point) Responses 12 kph 12 kph 3 kph 3 kph 16 kph 16 kph 9 kph 9 kph
To find the ascent rate in kilometers per hour, divide the distance (3/4 kilometer) by the time (1/16 hour):
(3/4 kilometer) / (1/16 hour) = (3/4) / (1/16) = (3/4) * (16/1) = 48/4 = 12.
Therefore, the mountain hiker's ascent rate is 12 kph.
if 3 dozen muffins cost 9, whats the cost per muffin
If 3 dozen muffins (which is equal to 36 muffins) cost $9, then the cost per muffin can be found by dividing the total cost by the number of muffins.
$9 / 36 muffins = $0.25 per muffin.
So the cost per muffin is $0.25.
Which of these equations is a non-proportional relationship?(1 point) Responses y=−15x y is equal to negative 15 x y=23x y is equal to 2 thirds x y=10x+10 y is equal to 10 x plus 10 y=4.08x
A non-proportional relationship occurs when the ratio between the variables is not constant.
The equation that represents a non-proportional relationship is: y = 10x + 10.
The other equations mentioned all represent proportional relationships.
The amount of money that Sarah earns varies directly with the number of hours worked. If Sarah earns $320 for working 40 hours, determine the constant of proportionality.(1 point) Responses 9 9 8 8 7 7 6
To find the constant of proportionality, divide the amount of money earned ($320) by the number of hours worked (40):
Constant of proportionality = $320 / 40 = $8.
Therefore, the constant of proportionality is $8.
