Cami buys 4 pounds of ground beef for $22. The total cost in dollars, y, is proportional to the number of pounds purchased, x pounds ground beef y=what.
Answer:
88
Step-by-step explanation:
The total cost of y 4 pounds of ground beef which is bought by Cami at the rate of $22 per pound of ground beef is $88.
What is the total cost?Total cost or the final cost is the summation of all the cost spend while buying any good or taking any service.
Cami buys 4 pounds of ground beef for $22. The total cost in dollars, y, is proportional to the number of pounds purchased, x pounds ground beef.
In this problem, the total cost y has to be found out. As the price of one pound of ground beef is $22 and there is total 4 pounds of ground beef, Cami bought.
Thus, the total cost is,
[tex]y=22\times44\\y=88[/tex]
Thus, the total cost of y 4 pounds of ground beef which is bought by Cami at the rate of $22 per pound of ground beef is $88.

A model rocket is launched directly upward at a speed of 15 meters per second from a height of 10 meters. The function f(t)=−4.9t2+15t+10, models the relationship between the height of the rocket and the time after launch, t, in seconds. When, in seconds after launch, will the rocket reach its highest point? Round to two decimal places.
Answer:
Step-by-step explanation:
To find the highest point we use t = -b/2a (because that's the equation used to find the maximum of the function which is the maximum height the rocket reaches before heading back down ( aka highest point of the parabola at the turning point)
f(t) = -4.9t^2 +15 +10
A = -4.9
B = 15
C=10
Plug it in
-15/2(-4.9) = 1.53 seconds
(In case you get confused 15 turns negative because b in the equation has a - symbol in front. If you had -15 as B you would put -(-15) making it positive)
Hope this is helpful
1.53seconds after launch, will the rocket reach its highest point.
What is height?In mathematics, height is defined as the vertical distance from the top of an object to the bottom. Sometimes it is labeled as "height".
The term height in geometry refers to the measurement of an object along the y-axis in coordinate geometry.
Height is a way of measuring someone or something from the bottom to the top or from the head to the feet. In other words, height indicates how tall someone or something is. We can compare how tall we will be when we grow up. We often compare the average height of men and women in different countries.
Given:
f(t)=−4.9t2+15t+10
The vertex is the highest point of the function
when t= [tex]\frac{-b}{2a}[/tex]
=[tex]\frac{-15}{2(-4.9)}[/tex]
≈ 1.53
f(t) is the maximum value
1.53seconds after launch, will the rocket reach its highest point.

In circle B with the measure of minor arc AC= 84°, find m
Answer:
m<ADC = 42°
Step-by-step explanation:
Based on the inscribed angle theorem, the inscribed angle, m<ADC is ½ the measure of minor arc AC.
If minor arc is given as 84°, therefore:
m<ADC = ½(84)
m<ADC = 42°

Find the Area of the figure below, composed of a rectangle and a semicircle. Round to
the nearest tenths place.
10
6
Can somebody please help me
Answer:
Area = 74.1 square units
Step-by-step explanation:
Area of the composite figure = Area of the rectangle + Area of the semicircle
Area o the rectangle = Length × Width
= 10 × 6
= 60 square units
Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]
Here, r = radius of the semicircle
For the semicircle with radius = [tex]\frac{6}{2}[/tex] = 3 units
Area = [tex]\frac{1}{2}\pi (3)^{2}[/tex]
= 4.5π
= 14.14 units²
Total area of the composite figure = 60 + 14.14
= 74.14 square units ≈ 74.1 square units
