Answer:
24 inches.
Step-by-step explanation:
In order for a triangle to be obtuse, one of its angles must be greater than 90 degrees. In a right triangle, the angle opposite the hypotenuse is always 90 degrees, so in order for the triangle to be obtuse, the hypotenuse must be the longest side.
To find the lowest whole number side length in inches that would ensure that the triangle is obtuse, we can use the Pythagorean theorem. The Pythagorean theorem states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
a^2 + b^2 < c^2
If we take the base 48cm and convert it to inches, 48cm = 48*0.393701 = 18.897638 inches
So the base is 18.897638 inches.
Now we have to find the lowest whole number side length of c so that:
18.897638^2 + b^2 < c^2
358.565744 + b^2 < c^2
We can see that the lowest whole number of c is 24 inches.
So, the lowest whole number side length in inches that would ensure that the triangle is obtuse is 24 inches.

What is a 140 degree angle called?.
Answer:
Obtuse
Step-by-step explanation:
An angle that is measured more than 90 degrees is an obtuse angle. Although an angle that measures 180 degrees is a straight angle or a half angle, and an angle that measures 360 degrees is a straight angle or a complete angle. However, when it's 360 degrees it's a full circle because a circle measures 360 degrees. If you want to measure an angle to determine which one it is, you must use a protractor.

Supplementary angles are two angles that have measures with a sum of 180°. Angles 1 and 2 are supplementary and the measure of angle 2 is 3° more than twice the measure of angle 1.
The measure of Supplementary angles is ∠1 is 59° and ∠2 is 121°.
What are Supplementary angles?The word "supplementary" refers to two angles coming together to form a straight angle. It indicates that when two angles sum up to 180 degrees, they are said to be supplementary angles. If two angles complement one another.
It has an acute angle on one side and an obtuse angle on the other.
The angles are both right angles.
Given ∠1 and ∠2 are supplementary angles,
let ∠ 1 = x°
∠1 + ∠2 = 180°
so ∠2 = 180 - x
angle 2 is 3° more than twice the measure of angle 1,
and ∠2 = 3 + 2x
substitute the values
∠2 = 180 - x
3 + 2x = 180 - x
2x + x = 180 - 3
3x = 177
x = 177/3
x = 59°
∠2 = 180 - x
∠2 = 180 - 59

Why do trigonometric ratios only depend on the angle?.
Trigonometric ratios depend only on angles as they remain constant no matter what.
Triangle side length ratios are known as trigonometric ratios. In trigonometry, these ratios show how the ratio of a right triangle's sides relate to each angle. Sine, cosine, and tangent ratios are the three fundamental trigonometric ratios. The sin, cos, and tan functions can be used to obtain the other significant trigonometric ratios, cosec, sec, and cot.
Even if the sides of the triangle increases or decreases in a specific ratio, the angles of the triangle will always remain the same no matter what.
Trigonometric ratios in right triangles are therefore independent of the side lengths and solely depend on the magnitude of the angles.

3100 dollars is placed in an account with an annual interest rate of 7.25%. To the
how long will it take for the account value to reach 25300 dollars?
nearest year,
Answer: 8.46 years
Step-by-step explanation:
To find out how long it will take for the account value to reach $25,300, you would need to use the formula:
A = P(1 + r/n)^(nt)
Where:
A is the final amount (25,300)
P is the initial amount (3,100)
r is the annual interest rate (7.25%)
n is the number of times the interest is compounded per year
t is the number of years
In this case, we can assume that the interest is compounded annually, so n=1.
We can then plug in the values and solve for t:
25,300 = 3,100(1 + 0.0725)^t
t = (ln(25,300/3,100)) / (ln(1 + 0.0725))
t ≈ 8.46 years
So it would take approximately 8.46 years, rounded to the nearest year.

The speed of a point on the wheel rim is 35000π cm/s (2500 rev/min and 14cm diameter).
what is circumference ?
Circumference is the distance around the edge of a circle. It can be calculated using the formula: C = 2πr, where C is the circumference and r is the radius of the circle.
To express the speed of a point on the rim of the wheel in centimeters per second, we first need to find the circumference of the wheel using the diameter. The circumference can be found using the formula: C = 2πr, where C is the circumference and r is the radius of the wheel.
Since the diameter is 14cm, the radius of the wheel is 14/2 = 7cm.
Therefore, the circumference of the wheel is: C = 2π(7) = 14π cm
Next, we need to find the distance traveled by a point on the rim of the wheel in one revolution. This distance is equal to the circumference of the wheel.
So, the distance traveled by a point on the rim of the wheel in one revolution is: 14π cm
To find the speed in centimeters per second, we need to multiply the distance traveled in one revolution by the number of revolutions per minute.
The wheel rotate 2500 revolution per minute.
The speed of a point on the wheel rim is 35000π cm/s (2500 rev/min and 14cm diameter).

• Adult Women: Children = 5:2
The difference between the number of Adult Males and Adult Females is 28.
Find the number of children in the village.
Answer:
24 children
Step-by-step explanation:
Given ratios:
Adult Males: Children = 11 : 3Adult Females : Children = 5 : 2Multiply the first ratio by 2 and the second ratio by 3 so that the ratios of children are the same:
Adult Males: Children = 11 × 2 : 3 × 2 = 22 : 6Adult Females : Children = 5 × 3 : 2 × 3 = 15 : 6Therefore the combined ratio is:
Adult Males : Adult Females : Children = 22 : 15 : 6So the ratio of Adult Males to Adult Females is 22 : 15.
If the difference between the number of Adult Males and Adult Females is 28 then:
[tex]\implies \dfrac{22}{22+15}x-\dfrac{15}{22+15}x=28[/tex]
[tex]\implies \dfrac{22}{37}x-\dfrac{15}{37}x=28[/tex]
[tex]\implies \dfrac{7}{37}x=28[/tex]
[tex]\implies 7x=1036[/tex]
[tex]\implies x=148[/tex]
Therefore:
[tex]\implies \textsf{Adult Males}=\dfrac{22}{37} \times 148=88[/tex]
[tex]\implies \textsf{Adult Females}=\dfrac{15}{37} \times 148=60[/tex]
If the original ratio of Adult Males to Children is 11 : 3, and the number of Adult Males is 88:
[tex]\implies 11:3=88:c[/tex]
[tex]\implies \dfrac{11}{3}=\dfrac{88}{c}[/tex]
[tex]\implies 11c=264[/tex]

Dividing the total time of 3 hours by the number of users which is 2, we get 3 hours / 2 = 1.5 hours. This means each person, Emilia, and her brother, use the computer for 1.5 hours each.
It's important to note that this is possible because they both agreed to share the computer equally. If one of them needed more time than the other, they might have to work out a different arrangement.

1. If you have a locker with 40 different numbers on it, how many different combinations
can you create? Remember that you have three numbers on a locker.
What is the probability that someone can randomly guess it on the first try? (take your
answer from the first part and make it 1/that number).
Answer:
1/9880
Step-by-step explanation:
Number of Combinations
[tex]\displaystyle C(40,3)=\frac{40!}{3!(40-3)!}=\frac{40!}{3!\cdot37!}=\frac{40*39*38}{3*2*1}=40*13*19=9880[/tex]
Thus, the probability of guessing that exact combination on the first try is 1/9880.
How do you graph an absolute value function example?.
The one example of absolute value function is x =|y| , and the graph is sketched below .
What is Absolut value Function ?
The absolute value function is defined as a function in algebra that consists of the variable in the absolute value bars. The general form of absolute value function is written as f(y) = a |y - h| + k .
let the absolute value function be : x = |y| ;
we put y = -1 , we get ⇒ x = 1 ;
we put y = 1 , we get ⇒ x = 1 ;
we put y = 0 , we get ⇒ x = 0 ;
from the above points we observe that , what ever we put in the function , the result "x" is always positive .
Therefore , the graph of the function x = |y| , is a V shaped graph that faces Right .
