A chili recipe calls for 2 pounds of ground pork and 3.5 pounds of ground beef. The cost of ground beef per pound is $0.20 less than twice the cost of ground pork. If the total cost of meat for the recipe is $15.05, what is the cost per pound of ground pork?
Answer: [tex]\$1.75\ \text{per pound}[/tex]
Step-by-step explanation:
Given
The recipe calls for 2 Pounds of ground pork and 3.5 pounds of ground beef
Suppose x is the cost of ground pork
So, the cost of ground beef is [tex]2x-0.2[/tex]
The total cost of meat is [tex]\$15.05[/tex]
The total cost can also be written as
[tex]\Rightarrow 2\times x+3.5\times (2x-0.2)=15.05\\\Rightarrow 2x+7x-0.7=15.05\\\Rightarrow 9x=15.75\\\Rightarrow x=\frac{15.75}{9}=\$1.75\ \text{per pound}[/tex]
So, the cost of ground pork is [tex]\$1.75\ \text{per pound}[/tex]
10 p What is the common ratio for the following geometric sequence? 640, 160.40.10....
Answer:
r = [tex]\frac{1}{4}[/tex]
Step-by-step explanation:
The common ratio (r) of a geometric sequence is the ratio of any term divided by the previous term , then
r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{160}{640}[/tex] = [tex]\frac{1}{4}[/tex]
An architect is making a plan for a new circular playground. If the playground needs to be surrounded by a fence and the diameter of the playground is 25 meters, how much fencing needs to go up?
Answer:
78.54 m
Step-by-step explanation:
To obtain how much circular fence, we obtain the Circumference of the circular playground.
The Circumference of a circle, C = 2*pi*r
pi = 3.14 ; r = diameter / 2 = 25 /2 = 12.5 m
C = 2 * 3.14 * 12.5
C = 78.539816
Hence, the fencing which need to go up is ;
78.54 m

After 5 games Adrian Peterson has rushed for 498 yards. If he gains 4.5 yards per carry, how many carries will it take for him to reach 1200 yards
Answer:
156 carries
Step-by-step explanation:
Given that:
5 games = 498 yards
Number of yards Gained per carry = 4.5 yards
Target number of yards = 1200
Number of yards left to reach target :
1200 - 498 = 702 yards
Number of carries required = number of yards / yards per carry
Number of carries required = 702 / 4.5
= 156 carries

13. A cone with a radius of 3 inches and a height of 7 inches has the same radius as a cylinder. If the cylinder's volume is two times the volume of the cone, what is the height of the cylinder? Use 3.14 for pi
Answer:
Step-by-step explanation:
r = 3 in
h = 7 in
volume of cone = ⅓πr²h = 21π in³
cylinder has radius r = 3 and height h.
volume of cylinder = πr²h = 9πh in³
volume of cylinder is two times the volume of cone
9πh = 2×21π
9h = 42
h = 42/9 = 4⅔ in
