Mary used one big bag of flour. She baked four loaves of bread. Then, she used the remaining flour to make 48 muffins. How much
1 answer:
Answer:
Amount of flour in the bag when Mary began =
Step-by-step explanation:
Given:
Number of baked loaves of bread made from flour = 4
Number of muffins made from flour = 48
To find: Amount of flour in the bag when Mary began
Solution:
Let x denotes amount of flour used to make one baked loave of bread and y denotes amount of flour used to make one muffin.
So,
Amount of flour used to make 4 baked loaves of bread = 4 x
Amount of flour used to make 48 muffins = 48 y
Amount of flour in the bag when Mary began =

Here is the full question:
Another plan to secure the roller coaster involves placing two concrete struts on either side of the center of the leg of the roller coaster to add reinforcement against southerly winds in the region. Again, using the center of the half-circle as the origin, the struts are modeled by the equations and . A vertical reinforcement beam will extend from one strut to the other when the two cables are 2 feet apart.
Graph the two struts on the model of the roller coaster. Take a screenshot of your graph and paste the image below, or sketch a graph by hand.
Recall that a reinforcement beam will extend from one strut to the other when the two struts are 2 feet apart.
(a) Algebraically determine the x -value of where the beam should be placed.
(b) Explain where to place the beam
Step-by-step explanation:
Find attached the graphing calculator.
(a) The x-value where the beam should be placed is x = -4
(b) The beam should be placed directly above 4 feet from the center.
