In an isosceles triangle with a base of 7 units, the two other sides have to be greater than 3.5 units but less than 7 units due to the triangle inequality theorem, which means each side must always be shorter than the sum of the other two sides.
Explanation:An isosceles triangle is a triangle with two sides of equal length. If the base of the triangle is 7 units, the lengths of the other sides could be any value greater than 3.5 units but less than 7 units. This principle is rooted in the triangle inequality theorem which states that any side of a triangle always needs to be shorter than the sum of the other two sides.
So in this case, since the base is 7 units, the other two equal sides (let's call them 'a' and 'b') could be, for example, 5 units each, but don't forget they must fulfill two conditions: firstly, 'a' + 'b' > 7 (which is true if both 'a' and 'b' are more than 3.5 units), and secondly, 'a' + 7 > 'b' as well as 'b' + 7 > 'a' (which are true as long as 'a' and 'b' are less than 7 units). Consequently, both 'a' and 'b' could be a range of lengths, but they must be greater than 3.5 units and less than 7 units in order to ensure that the triangle inequality theorem is respected.

A) 31 m3
B) 94 m3
C) 188 m3
D) 283 m3
Answer:
It is 94
Step-by-step explanation:
The volume of a cone with a height of 10 meters and a radius of 3 meters is
94 m³.
What is a cone?A cone is a three-dimensional geometric shape with a smooth and curving surface and a flat base, with an increase in the height radius of a cone decreasing to a certain point.
The volume of a cone is (1/3)πr²h.
The total surface area of a cone is πr(r + l).
The curved surface area is πrl.
Given, A cone has a radius of 3 meters and a height of 10 meters.
Therefore, The volume of this cone is,
= (1/3)π(3)²×10 m³.
= 30π m³.
= 30×3.14 m³.

The table shows equivalent ratios. Find the missing numbers in the table.
x y
2
4 16
6 24
8
Answer:
(2,8) and (8,32)
Step-by-step explanation:
ratios can be written as x:y or x/y
so look at what is given
(4,16)....4/16 reduces to 1/4
(6,24)...6/24 reduces to 1/4
so the pattern is ur either dividing y by 4 and getting x....or ur multiplying x by 4 and getting y
and since ur other 2 points given dont have y, we will multiply x by 4 to get y.
(2,y).....lets multiply x, which is 2, by 4......2 * 4 = 8
so ur point is (2,8)
(8,y).....multiply x, which is 8, by 4.....8 * 4 = 32
so ur point is (8,32)

Determine whether each number could be the probability of an event. Explain your reasoning.
1.5
1
Answer:
1.5--> Not a probability
1---> Can be a probability
Step-by-step explanation:
The range of the probability of an event is given by 0≤P(E)≤1
The probability of an event E, P(E) cannot be greater than 1.
This means P(E)≠1.5
P(E)=1 could be a probability of an event because it falls within the range.
Probability of an event being 1, means the event is certain to happen.

denise is using a ladder to clean the outside of her second story windows. the ladder she is using is 24 feet long and she puts the base of the ladder 13 feet away from the house in order to avoid her flower gardens. how high up the side of her house does the ladder reach? round to the nearest tenth, if necessary
Answer:
20.2 ft
Step-by-step explanation:
First, always draw a diagram to help you solve the problem. (See the picture below). The situation forms a right triangle. We can assume the ground and the house and perpendicular, creating the 90° angle. The ladder is the hypotenuse.
Since we have a right triangle, and we have one missing side, we can solve the problem using the Pythagorean Theorem, which is a² + b² = c². "a" and "b" are the perpendicular sides and the "c" is the hypotenuse.
Assign a variable for the missing side (not the hypotenuse!)
let "b" represent the height the ladder reaches on the house
Use the formula and substitute the other known values. Then, isolate 'b' to solve by doing the reverse operations in the reverse order of BEDMAS.
a² + b² = c²
13² + b² = 24² Substitute the two known sides.
13² - 13² + b² = 24² - 13² Subtract 13² from both sides
b² = 24² - 13² Cancelled out positive 13² on the left side
√b² = √(24² - 13²) Square root both sides
b = √(24² - 13²) "b" is isolated because √ and ² are reverse operations
b = √(576 - 169) Square the numbers inside the bracket. Subtract.
b = √407 Find the square root
b = 20.174241 Round this number to nearest tenth
b ≈ 20.2 Answer in feet units
Remember when rounding, you round either up or down depending on the digit to the right of what you are rounding to.
"The nearest tenth" is rounding to the first decimal. To the right of the first decimal is '7'. Since '7' is "5 or greater" you round up. If '7' was "4 or less", you would round down.
Therefore, the ladder reaches 20.2 feet up the side of the house.
Using the Pythagorean theorem, we find that the ladder reaches approximately 20.2 feet up the side of Denise's house when the base is placed 13 feet away from the building.
Denise is using a 24-feet long ladder and placing the base of the ladder 13 feet away from her house. To calculate how high up the side of her house the ladder reaches, we can use the Pythagorean theorem. This theorem states that in a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this scenario, the hypotenuse is the ladder, one side is the distance from the house, and the other side is the height the ladder reaches up the house.
To find the height (h), we can set up the equation: h^2 + 13^2 = 24^2. Calculating further, we get h^2 = 24^2 - 13^2, which simplifies to h^2 = 576 - 169. This gives us h^2 = 407. Taking the square root of both sides, we find that h is approximately 20.2 feet when rounded to the nearest tenth.

The probability that an event will happen is P(E)=
23/37. Find the probability that the event will not happen,
The probability that the event will not happen is
Answer:
14/37
Step-by-step explanation:
P(E) = 23/37
P(not E) = 1 − P(E)
P(not E) = 1 −23/37
P(not E) = 14/37
The probability that the event will not happen is approximately 0.3784 or 37.84%, calculated by subtracting the probability of the event from 1.
Explanation:In probability, the likelihood of an event occurring and not occurring always adds up to 1. This principle is called the Law of Total Probability.
Given the probability that the event will happen is P(E)= 23/37. To find the probability that the event will not happen, you need to subtract the probability of the event occurring from 1.
So, the probability that the event will not happen, often written as P(E') or P(not E), is calculated as follows:
First convert the fraction 23/37 to a decimal. This equals approximately 0.6216.Then, subtract this decimal from 1. This equals approximately 0.3784.Therefore, the probability that the event will not happen is approximately 0.3784 or 37.84%.
