An inequality to represent the dollar amounts d in cash and prizes Regan can win is p + d ≥ 500.
What are inequalities?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
Given that, Regan won the grand prize at a store giveaway. The grand prize winner is guaranteed to win at least $500 in cash and prizes.
Let d represent the amount of cash in dollars and p represent the amount of prizes.
Since the grand prize winner is guaranteed to win at least $500,
So, p + d ≥ 500
Therefore, an inequality to represent the dollar amounts d in cash and prizes Regan can win is p + d ≥ 500.

What is a triangle?A polygon with three vertices and three sides is called a triangle. The triangle's angles are created by joining its three sides end to end at a single point. The sum of the three angles of the triangle is 180 degrees.
Given a ΔSTU
a line from point T intersects at SU at point V and divides SU, given SV is 60 units and UV is 42 units.
The line TV is not a median, because a median divides the side into two equal halves, and the figure does not have SV equal to UV.
The line TV is not an attitude because the figure has not specified the angle of V in line SU, if given that the ∠TVU = ∠TVS = 90° then TV will be called altitude.
The line is not a perpendicular bisector because The line segment drawn from a vertex to the opposite side of a triangle, bisecting that side at a right angle, is known as the perpendicular bisector of the triangle.
Hence option D is correct.

Borrowed 600$ from the bank. Interest is $14.25 for 90 days. What is interest rate?
Answer:
0.01 %
Step-by-step explanation:
The interest rate is the percentage of the principal (the amount borrowed) that is charged as interest over a certain period of time.
To find the interest rate, we can use the formula:
Interest Rate = Interest / Principal x Number of days / 365
We know that the principal is 600$, the interest is 14.25$ and the number of days is 90
so we can substitute the values into the formula:
Interest Rate = 14.25 / 600 x 90 / 365
Interest Rate = 0.02375 * 90 / 365
Interest Rate = 0.0104
Rounded to the nearest thousandth, the interest rate is 0.010 or 0.01 %

930 = -20×|t - 15| + 1010
one solution is for (t - 15) > 0
930 = -20×(t - 15) + 1010
-80 = -20×(t - 15)
4 = t - 15
t = 19
that means 2019.
the second solution is for (t - 15) < 0
930 = 20×(t - 15) + 1010
-80 = 20×(t - 15)
-4 = t - 15

One aircraft has a capacity of 64 more seats than a second aircraft. A third aircraft has 152 seats less than twice the seating capacity of the second aircraft. If their total number of seats is 1900, find the number of seats for each aircraft.
The number of seats in the first, second and third aircraft are 561 seats, 497 seats and 842 seats respectively
How to find the number of seats for each aircraft?A word problem is a mathematical exercise where significant background information on the problem is presented in ordinary language rather than in mathematical notation
Let F, S and T represent number of seats in the first, second and third aircraft respectively
We can set up three equations to represent the situation:
F = 64 + S --- (1)
T = 2S - 152 --- (2)
F + S + T = 1900 --- (3)
Put (1) and (2) in (3):
F + S + T = 1900
(64 + S) + S + (2S - 152) = 1900
64 + S + S + 2S - 152 = 1900
4S - 88 = 1900
4S = 1900 + 88
4S = 1988
S = 1988/4
S = 497 seats
F = 64 + S
F = 64 + 497 = 561 seats
F + S + T = 1900
561 + 497 + T = 1900
1058 + T = 1900
T = 1900 -1058 = 842 seats

Mark plays field hockey. He makes a goal 55% of the time he shoots. A = the event Mark is successful on his first goal attempt. P(A) = 0.55. B = the event Mark is successful on his second goal attempt. P(B) = 0.55. Mark tends to make goals in streaks. The probability that he makes a second goal given that he made the first goal is 0.80.
If Mark attempts two goals, what is the probability that he makes both goals?
Answer:
We can use the formula for conditional probability to find the probability that Mark makes both goals:
P(A and B) = P(A) * P(B | A)
We know that:
P(A) = 0.55 (the probability that Mark makes a goal on his first attempt)
P(B | A) = 0.80 (the probability that Mark makes a goal on his second attempt given that he made the first goal)
So:
P(A and B) = 0.55 * 0.80 = 0.44
Therefore, the probability that Mark makes both goals is 0.44.

B. The theoretical probability, P(gold), is 50%, and the experimental probability is 11.5%.
C. The theoretical probability, P(gold), is 25%, and the experimental probability is 25%.
D. The theoretical probability, P(gold), is 50%, and the experimental probability is 13.0%.
The correct option is A.
"The theoretical probability, P(gold), is 25%, and the experimental probability is 27.5%."
How to find the probabilities?First, let's find the theoretical probability.
We know that there are:
10 brown marbles10 black marbles10 green marbles10 gold marblesFor a total of 40 marbles.
The theoretical probability of randomly pulling a gold marble is equal to the quotient between the total number of gold marbles and the total number of marbles, it is:
P = 10/40
P = 1/4 = 0.25
For the experimental probability, we need to take the quotient between the number of times that the outcome of the experiment was a gold marble and the total number of times that the experiment was performed.
The experiment was performed 40 times and 11 times we got the gold marble, then:
E = 11/40 = 0.275

The way we should prepare the meal to supply one half of the RDA for protein and 139 grams pof carbohydrates is 4 beans serving and 5 bread slices (answer A). It not possible to have the same amount of protein as in part A but only 61 grams of carbohydrates.
How to calculate the meal of point A?To calculate the meal of point A we have to consider the amount of grams of protein and carbohydrates in each food. In this case, we try with 4 servings of beans and 5 slices of bread, and it get the protein and carbohydrates required as shown in the following explanation:
Servings of beans
4 * 5 = 20 grams of protein
4 * 21 = 84 grams of carbohydrates
Slices of bread
5 * 2 = 10 grams of protein
5 * 11 = 55 grams of carbohydrates
Totals
20 + 10 = 30 grams of protein
84 + 55 = 139 grams of carbohydrates
According to the previous explanation the meal have to be composed by 4 servings of beans and 5 slices of bread. On the other hand, if we want to make a meal with the same amount of protein but only 61 grams of carbohydrates, it is imposible because the amount of carbohydrates of each food is bigger than we need.

Answer:
The circumference of a tire can be found by using the formula C = πd, where C is the circumference, and d is the diameter.
For the old bicycle with 12 inch diameter tires, the circumference is:
C = π * 12 = 12 * π inches
For the new bicycle with 16 inch diameter tires, the circumference is:
C = π * 16 = 16 * π inches
To find the difference in the circumference of the tires, we subtract the circumference of the old tire from the circumference of the new tire:
16π - 12π = 4π inches
So the difference in the circumference of the two tires is 4π inches.
It's around 12.56 inches.

Chris earns $8 per hour working on the weekends. He needs at least $320.00 for his class trip. How many hours, h, does Chris need to work on the weekends to be able to go on the class trip
We can start solving the problem by using the formula:
Hours worked = Total cost / Hourly wage
In this case, we know that Chris needs at least $320.00 for his class trip, and he earns $8 per hour working on the weekends. So, we can plug in these values into the formula:
Hours worked = $320.00 / $8.00
To solve this equation, we divide 320 by 8:
Hours worked = 40
So Chris needs to work 40 hours on the weekends to be able to go on the class trip.
