A store is randomly giving away gift cards to the first 150 customers. They are giving 130 gift cards that have a value of $5 each and 15 gift cards that have a value of $50 each. The rest of the gift cards have a value of $100 each. Which is the probability that a customer will get a $100 gift card?
Answer:
1/30
Step-by-step explanation:
The total number of cards is 150. Subtract the numbers of the other values, 130 and 15 to get the number of $100 cards.
150 -145 = 5
5/150 is the number out of the total.
Simplify to get the probability: 1/30

You have 2 different savings accounts. For Account A, the simple interest earned after
6 months is $4.63. For Account B, the simple interest earned after 21 months is $16.80. If the interest rate is 3.7% for Account A and 2.4% for Account B, how much is the principal in each account? Which account earned you the most interest the first month? Explain your answer.
Step-by-step explanation:
The formula for simple interest is expressed as
I = PRT/100
Where
P represents the principal or initial amount of money invested.
R represents interest rate
T represents time
Considering the investment on account A,
I = $6.94
R = 3.7%
T = 9 months = 9/12 = 0.75 years
6.94 = (P × 3.7 × 0.75)/100 = 0.02775P
P = 6.94/0.02775 = $250
Considering the investment on account B,
I = $13.80
R = 2.3%
T = 18 months = 18/12 = 1.5 years
13.8 = (P × 2.3 × 1.5)/100 = 0.0345P
P = 13.8/0.0345 = $400
To determine the account that earned more interest in the first month,
250/9 = $27.8
400/18 = $22.2
Account A earned you the most interest the first month because $27.8 is higher than $22.2

Two forces with magnitudes 300 pounds and 450 pounds, with an angle of 60° between them, act upon an object. What is the approximate magnitude of the resultant force?
The resultant force in the example presented is approximately 774 pounds.
What is magnitude?The magnitude or size of a mathematical item defines whether it is larger or smaller than other objects of the same kind in mathematics.
Formally speaking, the size of an object is the visible outcome of an ordering—of the class of objects to which it belongs.
Consider the following scenario: the force is 10 N in the east.
The direction is indicated by "towards the east," while the force is indicated by "10."
Magnitude can be thought of as simply the "value" or "amount" of any physical quantity.
So, an object is under the influence of two forces with respective magnitudes of 300 pounds and 450 pounds and an angle of 60 degrees between them.
F₁=300 pounds, F₂=450 pounds and θ=60°
Fr=√300²+450²+2×300×450×cos60°
= √90000+502500+13500×0.5
= √90000+502500+6750
= √599250
= 774 pounds
Therefore, the resultant force in the example presented is approximately 774 pounds.

Which term makes the equation y=sup(x,3)+2x+1 nonlinear?
Answer:
sup(x,3)
Step-by-step explanation:
Linear equation:
A linear equation has the following format:
[tex]y = ax + b[/tex]
In a linear equation, when x changes by 1, y will always change by the amount a, which is called slope.
In this question:
y=sup(x,3)+2x+1
[tex]y = 2x + 1[/tex] would be a linear equation.
However, the expression sup(x,3), that is, the higher value between x and 3, means that the function is not linear.
you need 1661.06 ft squared of carpet to completely cover the floor or a round room. what is the diameter of the room.
Answer:
46 ft
Step-by-step explanation:
A = π×d²/4
d² = √4×A /π
= √4×1611.06 / 3.14
=√ 2116
= 46 ft
Answer:
46 feet squared
Step-by-step explanation:
A = π×d²/4
d² = √(4×A /π)
= √(4×1611.06 / 3.14)
= 2116
= 46 ft squared
For the image above, which action below allows the scale to be balanced?
Add 3 blocks to the right side.
Add 4 blocks to the right side.
Take away 3 blocks from the left side.
Take away 5 blocks from the left side.
Answer:
B is correct
Step-by-step explanation:
I took the flvs test
The action to make both side balanced
Take away 5 blocks from the left side.
What is Balanced?In science, if an object is still, we say it is balanced. An object is in an equilibrium state when it is balanced. Any forces acting on the object are counterbalanced by forces moving the other way. The average location of the gravitational pull on an object is known as the centre of gravity.
We have the figure.
On right side there are total 8 weights.
and, on left there are total 3 weights.
So, the difference of blocks on
= 8- 3
= 5 blocks
So, take away 5 blocks from left.

Mark monitors the growth of a colony of bacteria in his biology lab. He begins with a colony of 100 bacteria. After 24 hours, the colony has grown to 305
bacteria. After 24 more hours, the colony consists of 897 bacteria. What is a reasonable estimate of how many bacteria he can expect to count in the colony
when he returns 24 hours later?
Answer:
After next 24 hours, bacterial population would be [tex]1433[/tex]
Step-by-step explanation:
The initial bacterial count at time = 0 was [tex]100[/tex]
At [tex]= 24[/tex] hours, the bacterial count increased up to [tex]305[/tex]
At [tex]= 48[/tex] hours, the bacterial count increased up to [tex]897[/tex]
As we know that
[tex]P = P_0 * e^{rt}[/tex]
The growth rate of bacterial population is equal to
[tex]r = \frac{log\frac{P}{P_0} }{t}[/tex]
Substituting the above values we get -
[tex]r = \frac{log\frac{897}{305} }{24}\\r = 0. 0195[/tex]
Count of bacteria after next 24 hours
[tex]P = 897 * e^{ 0.0195 * 24)\\P = 1433[/tex]
