Given:
The diameter of a circle = 20 feet
To find:
The exact circumference of the circle.
Solution:
We know that the radius is half of the diameter of the circle.
The diameter of a circle is 20 feet. So, the radius of the circle is 10 feet.
The circumference of the circle is:
[tex]C=2\pi r[/tex]
Where, r is the radius.
Substituting [tex]\pi = 3.14, r=10[/tex], we get
[tex]C=2(3.14)(10)[/tex]
[tex]C=(6.28)(10)[/tex]
[tex]C=62.8[/tex]
Therefore, the exact circumference of the circle is 62.8 feet.
Note: All options are incorrect.

A survey shows that the probability of students choosing a career in medicine is 11 out of 50. Predict how many students out of 500 will enter the medical field.
Answer:
110?
Step-by-step explanation:

500/50= 10
so:
10×11= 110
What is the slope, m, and the y-intercept of the line that is graphed below?
Answer:
m=1 (0,3)
Step-by-step explanation:
m=1
slope is 1 because from left to right the line goes up and you move one 1and one to the left so m=1/1 =1
y-intercept is at (0,3) because is where the line intersects the y-axis

Help!, I need the answer in 30 minutes! For which values of the parameter p equation x ^ 2-px + 3 = 0 has a root in the range [0; 1], and another that does not belong to this range?
Answer:
p = 4
Step-by-step explanation:
Given the expression x ^ 2-px + 3 = 0
If x = 0 is a solution
Substitute into the expression
0² - 0p + 3 = 0
-0p = -3
p = 3/0
p cannot be determined for this root
If x = 1
1² - 1p + 3 =0
1 - p + 3 = 0
-p+4 = 0
-p = -4
p = 4
Hence the va;ue of p is 4
∠A and ∠ B ∠B are complementary angles. If m ∠ A = ( x − 23 ) ∘ ∠A=(x−23) ∘ and m ∠ B = ( 2 x + 29 ) ∘ ∠B=(2x+29) ∘ , then find the measure of ∠ B ∠B
Answer:
85
Step-by-step explanation:
2x + 29 + x - 23 = 180
solve for x = 28
b = 2 * 28 + 29 = 85
help, please !! you will get 10 points !!
Answer:
25.5
Step-by-step explanation:
Using SOH CAH TOA, you can see that x is the hypotenuse, and 24 is adjacent to the angle 20, so you will need to use CAH.
CAH is cos=adjacent/hypotenuse. Substituting our values in means cos(20) will be equal to 24/x. By cross multiplying, you receive cos(20) x =24. To find x, divide 24 by cos(20) to get 25.5 to the nearest tenth.

The sum of two numbers is 21 . One number is 12 more than the other one. Find the numbers.
Answer:
4.5 and 16.5
Step-by-step explanation:
4 + 16 = 20
5 + 17 = 22
(NUMBERS HAVE TO BE BETWEEN 4 - 5 AND 16 - 17)
4.5 + 16.5 = 21
16.5 - 12 = 4.5
Your carry-on bag weighs 25 pounds. Carry-on bags can weigh at most 50 pounds. Write and solve an inequality to represents how much more weight you can add to the bag and still meet the requirement.
Answer: Required inequality: [tex]25+x\leq 50[/tex]
we can add at most 25 pounds.
Step-by-step explanation:
Let x = Weight added.
As per given,
25 pounds + Weight added Must be less than or equal to 50 pounds
i.e. Required inequality: [tex]25+x\leq 50[/tex]
To solve , we subtract 25 from both the sides ,we get
[tex]x\leq 25[/tex]
hence, we can add at most 25 pounds.

Given: AM = 8, AB = 5x +1 and M is the midpoint of AB, find x and AB
X=
AB=
Answer:
x = 3
AB = 16
Step-by-step explanation:
Given: AM = 8, AB = 5x +1 and M is the midpoint of AB, the AM = MB
AB = 2AM
5x+1 = 2(8)
5x + 1 = 16
x = 16 - 1
5x = 15
x = 15/5
x = 3
Hence the value of x is 3
Since AB = 5x+1
AB = 5(3) + 1
AB = 15 + 1
AB = 16

Una botella de agua de 3/4 de litro de capacidad, tiene solo la mitad de líquido, ¿qué cantidad de litros de agua tiene la botella? *
A. 3/2 de litro
B. 3/8 de litro
C. 8/3 de litro
D. 1/2 de litro
Answer:
Amount of water in bottle = 3/8 liter
Step-by-step explanation:
Given:
Total capacity of bottle = 3/4 liter
Amount of water in bottle = 1/2 of total capacity
Find:
Amount of water in bottle
Computation:
Amount of water in bottle = [Total capacity of bottle[1/2 of total capacity]
Amount of water in bottle = [3/4][1/2]
Amount of water in bottle = 3/ [(4)(2)]
Amount of water in bottle = 3/8 liter

Answer:
0.47 (Yes - This is a terminating decimal)
0.16666... (Yes - This is a repeating decimal)
0.5473... (No - This is a decimal that neither terminates nor repeates)
0.462 (Yes - This is a terminating decimal)
Step-by-step explanation:
A terminating decimal and a repeating decimal are both types of decimals that can be written as fractions. However, if the decimal is neither of these types, it cannot be written as a fraction.
Tamara orders graphic novels. Each graphic novel costs $9.50. A one-time shipping fee of $12.25 is added to the cost of the order. The total cost of Tamara’s order before tax is $183.25. How many graphic novels did Tamara order?
Answer:
18 novels
Step-by-step explanation:
X= number of novels, 12.25 is a fixed fee.
9.50x+12.25=183.25
9.50x=171
x=18 novels

Akhil and Sonu are friends who study in the same school who attended their Assessment test, after they get their results, Akhil and
Sonu compared their scores. His friend Sonu claims that his score is a two-digit number, the sum of the digits of which is 14. The
number formed on reversing the digits of this number is 36 less than the number.
Read the paragraph carefully and answer the below question:
11.
1) What is the digit in the unit's place originally? help plsss
Answer:
digit in the unit's place originally = 5
Step-by-step explanation:
x + y = 14
xy - yx = 36
Now, the only single digits that sum up to 14 are;
9 + 5 = 14
8 + 6 = 14
We can't use 7 + 7 because they said there is a difference when the numbers are reversed.
Now, let's assume 95 is the original number since we are told when it is reversed it is lesser.
Thus, when reversed we have 59.
Difference = 95 - 59 = 36
Thus,unit number of original number = 5

What is the measurement of angle 1?
please help
Answer:
∠ 1 = 63°
Step-by-step explanation:
∠ 1 and 117° are adjacent angles and sum to 180° , that is
∠ 1 + 117° = 180° ( subtract 117° from both sides )
∠ 1 = 63°
I believe it is C. But if I’m wrong let me know :)
