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]

A tabletop in the shape of a trapezoid has an area of 7,205 square centimeters. Its longer base measures 115 centimeters, and the shorter base is 105 centimeters. What is the height?
Answer:
The height is 65.5 cm
Step-by-step explanation:
[tex]h=2*\frac{A}{a+b} \\\\h=2*\frac{7205}{115+105} \\\\h=2*\frac{7205}{220} \\\\h=2*\frac{131}{4} \\\\h=65.5[/tex]
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
A boat attempts to sail due east at 15km/h, but is taken off course by a current of 5 km/h flowing in the southwest direction. Find the resultant speed of the boat and the bearing on which it travels.
Answer:
10 km / hr
Step-by-step explanation:
Speed of boat = 15 km /hr
Speed of stream = 5km /hr .
Since both are acting opposite to each other . The the resultant speed with which it travels = 15 - 5 = 10 km/hr

Naomi‘s parents want to have $50,000 say to her college education if they invest $20,000 today in earn 7% interest compounded annually about how long will it take them to save the $50,000
Answer:
13 years
Step-by-step explanation:
Given data
A=50,000
P=20,000
r= 7%
t=??
The compound interest formula is given as
A=P(1+r)^t
Calculate time, solve for t
t = ln(A/P) / r
t= ln(50000/20000)/0.07
t= ln(2.5)/0.07
t= 0.916/0.07
t= 13.0
Hence the time is 13 years

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

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
