The radius of the circular base of a cone measures 2.6 inches, and its slant height measures 1.5 inches.
What is the approximate lateral area of the cone?
Use π≈3.14.
Enter your answer rounded to the nearest tenth in the box.
Answer:
11.6 sq. inches
Step-by-step explanation:
The lateral area of a cone can be found using the formula:
L = πrℓ
where r is the radius of the circular base and ℓ is the slant height.
Substituting in the given values, we have:
L = 3.14 x 2.6 x 1.5
L ≈ 11.6
Rounding to the nearest tenth, the approximate lateral area of the cone is 11.6 square inches.
find the missing value to the nearest hundredth cos__=7/18
67.11
37.67
22.89
21.25
The missing value is approximately 64.12 degrees, which is closest to option D: 21.25 using inverse cos.
The inverse cosine (or arccosine) of both sides of the equation must be taken in order to locate the missing value in the equation cos = 7/18 to the closest tenth. We will then be able to convert the value of to degrees and round it to the closest hundredth using the value of the radian that is produced.
cos θ = 7/18
= arccos(7, 18, 7)
A 1.1181 radian angle
We can use the conversion factor /180 to convert radians to degrees.
θ = 1.1181 × 180/π
64.12 degrees.
As a result, the figure that is lacking is roughly 64.12 degrees, which is closest to choice D: 21.25.
Due to the periodic nature of the cosine function, there are often two solutions when determining the inverse cosine of a value. But, since the problem states that we should round to the closest hundredth, which suggests a single answer, we can disregard the second option in this instance. By reinserting the value we discovered into the original equation and making sure it equals 7/18, we can further confirm that the result is accurate.

candace is designing a card game with a standard deck of cards. each player gets points based on collecting groups of cards. which statements are true about certain groups of cards? select all of the true statements.
The true statements are:
a) P(3) = 4/52 or 1/13
b) P(black number cards) = 18/26 or 9/13
c) P(red ace) = 2/52 or 1/26
d) P(face card) = 12/52 or 3/13
Define the term Probability?Probability deals with the study of random events and their likelihood of occurrence. It is computed by dividing the proportion of positive results by the total number of possibilities that could occur.
As we know that the standard deck card has 52 cards, in which 26 red cards (13 are diamonds, 13 are hearts) 26 black cards (13 are clubs, 13 are spades). Where 12 cards are face cards, 36 cards are number cards.
a) P(3) = 4/52 or 1/13: This is true. There are four 3s in a standard deck of 52 cards, so the probability is 4/52 or 1/13.
b) P(black number cards) = 18/26 or 9/13: This is a true. There are 26 black cards, out of those there are 9+9=18 black number cards (2 through 10), so the probability of drawing a black number card is 18/26 or 9/13.
c) P(red ace) = 2/52 or 1/26: This is true. There are two red aces in a standard deck of 52 cards, so the probability of drawing a red ace is 2/52 or 1/26.
d) P(face card) = 12/52 or 3/13: This is a true. There are twelve face cards in a standard deck of 52 cards, so the probability of drawing a face card is 12/52 or 3/13.
e) P(even number card) < P(odd number card): This is a false. There are 5×4=20 even number cards (2, 4, 6, 8, and 10 of each suit) and 4×4=16 odd number cards (3, 5, 7, 9 of each suit) in a standard deck of 52 cards. Therefore, the probability of drawing an even number card, (20/52 or 5/13) is greater than the probability of drawing an odd number card, (16/52 or 4/13).

A high school track team is traveling from Albany to Buffalo for a track meet. The coaches will rent vans that can seat 12 passengers for the trip. If n is the number of track team members and coaches traveling to the track meet, which function represents the number of vans needed for the trip?
Answer: The function that represents the number of vans needed for the trip is:
v(n) = ceil((n+c) / 12)
where ceil(x) is the smallest integer greater than or equal to x, n is the number of track team members, c is the number of coaches, and 12 is the number of passengers that can be seated in each van.
We need to add the number of coaches to the number of team members since they will all be traveling together. The result of the division should be rounded up to ensure that there are enough vans for everyone, even if there are only a few extra passengers.
Note: This assumes that all passengers will be traveling together in the same vans. If the coaches or some of the team members will be driving separately, the function may need to be adjusted accordingly.

Tolosa sold 540 eggs if these are 35% of total eggs,then how many eggs are not sold?
The total number of eggs is 1542.
To find the total number of eggs, we can use the fact that the 540 eggs sold represent 35% of the total eggs. We can start by setting up a proportion:
35/100 = 540/x
where x is the total number of eggs. To solve for x, we can cross-multiply and simplify:
35x = 54000
x = 54000/35
x = 1542.86
Therefore, the total number of eggs is approximately 1542.86. Since we can't have a fraction of an egg, we can assume that the total number of eggs is 1542.
To find the number of eggs that are not sold, we can subtract the number of eggs sold from the total number of eggs:

The equation of the line that contains the point (-6, 5) and is parallel to x + 2y = 14 in slope-intercept form is y = (-1/2)x + 2.
What are parallel lines?Due to their similar slopes, parallel lines move in the x direction with the same rate of change. If we know the slope of a line, we can use that slope to determine the slope of any line that is parallel to it. The point-slope form of a line can be used to get the equation of a line that is parallel to a given line and passes through a specified point.
The given equation of the line is:
x + 2y = 14
Rewriting the equation in standard form we have:
y = (-1/2)x + 7
where, -1/2 is the slope of the line.
The slope of two parallel lines are equal. Thus the slope of new line is m = -1/2.
Now, using the point slope form:
y - y1 = m(x - x1)
Substitute the values:
y - 5 = (-1/2)(x - (-6))
y - 5 = (-1/2)x - 3
y = (-1/2)x + 2
Hence, the equation of the line that contains the point (-6, 5) and is parallel to x + 2y = 14 in slope-intercept form is y = (-1/2)x + 2.

Pythagorean theoremThe side lengths of a right triangle will satisfy the relation given by the Pythagorean theorem. Here, that would require ...
54² +66² = 87²
2916 +4356 = 7569
7272 = 7569 . . . . . . . . . false — not a right triangle
Triangle WXY is not a right triangle, so XY is not tangent to circle W.
__
Additional comments
The parity of the integer side lengths of a right triangle is always even. That is, there can be two odd side lengths, but never just one odd side length.
Side lengths 54 and 66 are even, while length 87 is odd. There is only one odd side length, so this triangle cannot be a right triangle.
A tangent always meets a radius at right angles, so XY is a tangent if and only if angle X is a right angle.
Decide if the function is an exponential function. If it is, state the initial value and the base.y=5^x
Yes, the function y = 5^x is an exponential function.The initial value of an exponential function is the value of y when x = 0. In this case, when x = 0, y = 5^0 = 1. Therefore, the initial value of the function is 1.The base of an exponential function is the constant factor by which y changes when x increases by 1. In this case, when x increases by 1, y is multiplied by 5. Therefore, the base of the function is 5.
