Either decimal or fraction.
Answer:
3.0833
Step-by-step explanation:
i dont know how many 3's
Answer: 37/12
Step-by-step explanation: First you must turn 2 1/6 into a improper fraction, so 2x6 + 1 will get you 13 as the numerator and the denominator will be 6 so now we have 13/6 + 11/12. Now we must turn the denominator for 13/6 into 12 so, 13x2/6x2 so it is 26/12 so now the equation is 26/12 + 11/12 is 37/12.

Convert the rectangular coordinates (−2,2sqr3) to polar form. Let r>0 and 0≤θ<2π.
Enter your answer by filling in the boxes. Enter coordinates as simplifed fractions or radicals in simplest form.
Answer:
ler we have a point (x, y) and,
in molar form°
Z = √(x² + y² ) and 0 = tan-¹(y/x).
Since the point (2√3, -2) is in the fourth quadrant, make certain that your angle is also in the fourth quadrant.
17. There are 1,024 players in a tennis tournament. In each round, half the players are eliminated.
Which function can be used to find the number of players remaining in the tournament at the end of
x rounds?
A f(x) = 1,024(1.50)
B f(x) = 1,024(0.50)*
C f(x) = 1,024(1.05)
D f(x) = 1,024(0.50)x
Answer?
Answer:
1024(0.50)^x
Step-by-step explanation:
Initial value = 1024
Players eliminated per round =half = 50% of players in the round
Using the relation :
A(x) = P(1 - r)^x (decreasing hence, negative)
A(x) = 1024(1 - 50%) ^x
A(x) = 1024(1 - 0.50)^x
A(x) = 1024(0.50)^x

8. The soccer ball has a diameter of 9 inches. Find its volume.
Answer:
You do need to be more specific, the volume of a sphere is V = 4/3 π r^3, it does not need to be related to a cylinder. So if you know the radius, you can calculate the volume. The volume of a cylinder with the same radius and with a height of 2r (since it would be the diameter across) would be V = π r^2 h = 2π r^3.

Answer:
a) y = -2/5x + 3 b) (20, 19)
Step-by-step explanation:
a) slope of PQ => 24-9/22-16 = 15/6 = 5/2
perpendicular line have negative reciprocal slope = -2/5
substitute the new slope -2/5(m) and (5, 1) into the equation: y = mx + c to find the value of c
=> 1 = -2/5(5) + c
=> c = 3
plug in both the slope -2/5(m) and b = 3 into the equation: y = mx + c
=> y = -2/5x + 3
b) (2/3(22 -16), 2/3(24 - 9))=> (4, 10)
(16, 9) + (4, 10) = (20, 19)

Go to two decimal places
Answer:

Step-by-step explanation:
[(6.8 * 10^3) - (7.2 * 10^2)] ÷ 1.1 * 10^4
(6800 - 720) ÷ 11000
6080 ÷ 11000
6.08 * 10^3 ÷ 1.1 * 10^4

True or False:
x2 and -2x2 are like terms
Answer:
true i think....
Step-by-step explanation:
like terms have the same variables but don't need to have the same coefficients.
In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers.

2. A chemist has a 25% and a 50% acid solution. How
much should be used to form 250 mL of a 35% acid
solution?
A) 80 mL of 50% solutions and 120 mL of 25% solution
B) 150 mL of 50% solution and 50 mL of 25% solution
© 60 ml of 50% solution and 140 mL of 25% solution
D) 50 mL of 50% solution and 150 mL of 25% solution
E) None of the above
Answer:
x is mL of 25% acid and y is mL of 50% acid
We set up 2 equations:
A) x + y = 250
B) .25 x + .50y = .35 * 250 which equals
B) .25x + .50y = 87.50 Multiplying A) by -.5
A) -.5x -.5y = -125 adding the equations we get
-.25x = -37.50
x = 150 mL
y = 100 mL

Which equation is y = (x + 3)2 + (x + 4)2 rewritten in vertex form?
y = 2 (x + seven-halves) squared minus one-fourth
y = 2 (x + seven-halves) squared minus one-half
y = 2(x + 7)2 – 73
y = (x + 7)2 – 24
Answer:
The person above is correct B)y=2(x+7/2)²+1/2
Step-by-step explanation:
y = 2 (x + seven-halves) squared plus one-fourth equation is y = (x + 3)² + (x + 4)² rewritten in vertex form.
What is vertex form?If the vertex is (a, b), then the vertex form of an equation can be written as y = p(x-a)² + b, p is a constant.
How to solve this problem?Here, y = (x + 3)² + (x + 4)²
i.e. y = x² + 6x + 9 + x² + 8x + 16
i.e. y = 2x² + 14x + 25
i.e. y = 2x² + 2*2*(7/2)x + (7/2)² - (7/2)² + 25
i.e. y = 2(x + 7/2)² + 25/2 - 49/4
i.e. y = 2(x + 7/2)² + (50 - 49)/4
i.e. y = 2(x + 7/2)² + 1/4
Therefore, y = 2 (x + seven-halves) squared plus one-fourth equation is y = (x + 3)² + (x + 4)² rewritten in vertex form.
So, no option is correct.

Answer:
9442 lb
Step-by-step explanation:
First find the volume of the tank. This being a sphere, the volume is V =(4/3)π·r³. Here the diameter is 17 ft, so the radius, r, is half that: 8.5 ft.
Then the volume of the sphere is V = (4/3)π·(8.5 ft)³, and half that (the volume of the hemisphere) is (2/3)π·72.25 ft³.
Water weighs 62.4 lb/ft³. To find the weight of the water in the full tank, multiply the tank volume by this weight density 62.4 lb/ft³:
×
(2/3)π·72.25 ft³ · 62.4 lb/ft³ ≈ 9442 lb
