Find the arc length of the partial circle.
Either enter an exact answer in terms of t or use 3.14 for it and enter your answer as a decimal.
Answer:
9.42 Units
Step-by-step explanation:
Either enter an exact answer in terms of pi or us 3.14 for pi and enter your answer as a decimal.
The arc length of a partial circle whose radius is 8 and measure of the central angle is 90 degrees is 12.
To find the arc length of a partial circle, we can use the formula:
Arc Length (L) = θ × r,
where L is the arc length, θ is the central angle in radians (or degrees), and r is the radius of the circle.
In this case, the radius (r) is given as 8 units, and the measure of the central angle (θ) is given as 90 degrees. However, we need to convert the central angle from degrees to radians before plugging it into the formula, as trigonometric functions work with radians.
To convert degrees to radians, we use the conversion factor: π radians = 180 degrees.
θ (in radians) = 90 degrees × (π radians / 180 degrees) ≈ 1.57 radians.
Now, we can calculate the arc length:
Arc Length (L) = 1.57 radians × 8 units ≈ 12.

The length of a rectangle is 5 cm longer than its width.
If the perimeter of the rectangle is 30 cm, find its area.
Equation To write :2 {x+ ( x+5) }=30
Let's solve your equation step-by-step.
2(x+x+5)=30
Step 1: Simplify both sides of the equation.
2(x+x+5)=30
(2)(x)+(2)(x)+(2)(5)=30(Distribute)
2x+2x+10=30
(2x+2x)+(10)=30(Combine Like Terms)
4x+10=30
4x+10=30
Step 2: Subtract 10 from both sides.
4x+10−10=30−10
4x=20
Step 3: Divide both sides by 4.
4x

x=5
So... x+5=10.
Area =5x10=50 cm squared.
Answer:
5
Step-by-step explanation:
Okay, so P = perimeter, and the problem says P = 30
Let's call x the width, and y is the length.
In the perimeter formula, 2X + 2Y = P
so 2X + 2Y = 30
The problem also tells us that that x = y+5, so now let's do some substituting and replace X with Y+5
2(y+5) + 2Y = 30
2y+10 +2Y = 30
4y+10=30
-10. -10
4y=20
Y=5

The ratio of unshaded sections to shaded sections is;
Option D; 5 to 1
We are told that the diagram is divided into equal parts.
Now, from the given, we can see that there are 6 equal parts. However, out of the 6 equal sections, only one section is shaded while 5 sections are unshaded.
This means that the ratio of unshaded sections to shaded sections is; 5 to 1.
In conclusion, the ratio of unshaded sections to shaded sections from the given diagram that was divided into equal parts is; 5 to 1.

You walk from home to school. You graph the relationship between time, x, and distance from home, y. Which best describes the graph of your walk from home to school?
A. The graph will slope up and to the left
B. The graph will slope up and to the right
C. The graph will start at the origin and go up to the left
D. The graph will start at the origin and go up to the right
Answer:
The graph will start at the origin and slope up and to the right.
Using graph, the relationship between time x, and distance from home, y can be shown. The graph will start at the origin and go up to the right the best option is D.
What is graph?A graph is "diagrammatic or pictorial representations of collections of data in a organized manner".
According to the question,
The horizontal line or x-axis of the graph represents time taken during walk and the vertical line or y-axis of the graph represents distance traveled with respect to time.
Since walking start at home is taken as origin in the graph and reaching to school is noted in go up to the right of the graph.
Hence, using graph, the relationship between time x, and distance from home, y can be shown. The graph will start at the origin and go up to the right the best option is D.

Answer:
The sides are 3 and 9
Step-by-step explanation:
Since this is a right triangle, we can use the pythagorean theorem
a^2+b^2 = c^2 where a and b are the legs and c is the hypotenuse
x^2 + (3x)^2 = (3 sqrt(10))^2
x^2 + 9x^2 = 9*10
10x^2 = 90
Divide each side by 10
x^2 = 90/10
x^2 =9
Take the square root of each side
x = sqrt(9)
x = 3
The sides are x=3 and 3x = 3(3) = 9
Answer: x=10
Step-by-step explanation:
Since the original statements were x, 3x, and 3[tex]\sqrt{x}[/tex], is already given as 10 in 3[tex]\sqrt{x}[/tex], therefore, 3x is 3*10 and x is 10
The director of health services is concerned about a possible flu outbreak at her college. She surveyed
100 randomly selected residents from the college's dormitories to see whether they had received a
preventative flu shot. The results are shown below. What is the probability that a dormitory resident
chosen at random from this group has had a flu shot, given that he is male?
A)51/100
B)39/100
C)39/80
D)13/17
Answer:
39/100
Step-by-step explanation:
The question asks to find the probability that a dormitory resident
chosen at random from this group has had a flu shot, given that he is male.
As for that, the first thing to do is to look at the column where it says male.
Male:
39-Had Flu Shot
12-Did not have Flu Shot
Since the question is asking for the total number of males who did get a flu shot, it would be 39.
Lastly, to find probability, you have to use part over whole. The part would be 39. The whole would be the number of people selected to be tested. Therefore, the whole would be 100. That is why the probability that a dormitory resident chosen at random from this group has had a flu shot, given that he is male would be 39/100.
Answer:
39/100

A bottle contains 10.5 cups of orange juice. You drink 1.2 cups of the juice each morning and 0.9 cups of the juice each afternoon. How much total juice do you drink each day? When will you run out of juice?
Answer:
2.1 cups per day and you will run out of juice in 5 days.
Step-by-step explanation:
1.2 cups + .9 cups = 2.1 cups per day
10.5 divided by 2.1 = 5 days
From the equation calculated, 2.1 cups of juice will be drank daily.
The total juice that will be drank each day will be:
= 1.2 + 0.9 = 2.1
Therefore, 2.1 cups of juice will be drank daily.
The number of days before the person runs out of drink will be:
= 10.5 / 2.1
= 5
The person will use 5 days before running out of drink.

pls help :)
To solve you can use inverse operations.
Here are the steps to find the answer:
1. Write out the equation: -6(x-2)+3x= -3(x+3) +21
2. Distribute both sides: -6x+12+3x= -3x-9+21
3. Simplify both sides: -3x+12=-3x+12
4. This equation is true for all values, or infinity, because the equation is the same on both sides

In this question we are given the following values:
x = 2
y = -3
z = -1
Given the expression:
[tex] x^2 z^2 -y^2(x+z) [/tex]
To evaluate, let's substitute for 2, -3 & - 1 for x, y & z respectively
Therefore,
[tex] x^2 z^2 -y^2(x+z) [/tex]
Substituting values, we have:
[tex] (2^2) (-1^2) - (-3^2)(2+(-1)) [/tex]
Simplifying, we have:

Answer:
[tex]\frac{\sqrt{8} }{\sqrt{10} }[/tex]
Step-by-step explanation:
A perfect square is a number that has two identical factors, meaning it can be square rooted. The numbers 64 and 100 are an example:
8 · 8 = 64
10 · 10 = 100
So when you take the square root of [tex]\frac{64}{100}[/tex], you get:
[tex]\frac{\sqrt{8} }{\sqrt{10} }[/tex]
It doesn't say to simplify, so we can just leave it at that.
