There are 2000 pounds in a ton, and and you will add 330 for each dolphin. Your equation should look like this 2000+330+330 or 2000+(330*2)
= 2660
Answer:
Diameter of the smaller coin = 2.46 cm
Step-by-step explanation:
Circumference of a coin = 2πr
Circumference of coin A = 8.03 cm
Circumference of coin B = 8.03 cm - 0.33 cm
A.) what is the first step to find the diameter of the smaller coin?
Find the circumference of coin B
Circumference of coin B = 8.03 cm - 0.33 cm
= 7.7 cm
B.) Find the diameter of the smaller coin.
Circumference of a coin = 2πr
7.7 = 2 × 3.14 * r
7.7 = 6.28r
r = 7.7 / 6.28
r = 1.23 cm
Diameter = 2r
= 2 * 1.23 cm
= 2.46 cm
Diameter of the smaller coin = 2.46 cm
Answer:
3x + 3y - 3 units each
Step-by-step explanation:
An isosceles triangle is one that has two equal sides and angles.
given: perimeter = 7x + 5y - 8 units
base length = x - y -2 units
The length of each congruent sides can be determined as follows:
Let the length of the sides be represented by t. Since the sides have equal length, then;
7x + 5y - 8 = t + t + (x - y -2)
7x + 5y - 8 = 2t + (x - y -2)
⇒ 2t = 7x + 5y - 8 - (x - y -2)
= 7x + 5y - 8 - x + y + 2
collecting like terms,
2t = 6x + 6y - 6
= 2(3x + 3y - 3)
divide both sides by 2,
t = 3x + 3y - 3
Therefore, the congruent sides are 3x + 3y - 3 units each.
Step-by-step explanation:
b. f(x) is an exponential function =>
with the formula :
f(x) = 4^x , x ≥ -2
g(x) is a linear function =>
with the formula :
g(x) = x + 4 , x ≥ -1
c. f(x) will increase as geometric sequence
g(x) will increase as arithmetic sequence
d. f(x) = g(x)
4^x = x+4
x = 1.1875 (estimated)
Answer:
1. = station A
because 15 gallons = 0.75 discount at B but station A has a 1.50 discount at 15 gallons
Step-by-step explanation:
2. for satation B you have to read the graph
but for station A it is unclear on the graph
a way to work it out is that you know that 10= 1.00 so 12 = 1.2
( divide 12 by 10 )
station B = discount for 12 gallons = 0.6
but Station A = discount for 12 gallons = 1.2
the difference is
1.2 - 0.6 = 0.6 discount
