The number by which the circumference is multiplied is:
2
Step-by-step explanation:We know that the circumference of the circle in terms of the radius r is given by:
[tex]\text{Circumference}=2\pi r[/tex]
Now, if the radius is doubled.
i.e.
[tex]r'=2r[/tex]
Hence, the circumference of the new circle is given by:
[tex]\text{Circumference of new circle}=2\pi (2r)\\\\i.e.\\\\\text{Circumference of new circle}=2(2\pi r)[/tex]
i.e.
[tex]\text{Circumference of new circle}=2\times \text{Circumference of original circle}[/tex]
The constant by which the circumference is multiplied is: 2

Which term can be combined in the expression below? check all that apply. 5/6a - 2b - 16.3 + b/12 + c - 0.9b
Answer:
Option 2nd , 4th and 6th correct
[tex]-2b[/tex], [tex]\frac{b}{12}[/tex] and [tex]-0.9b[/tex]
Step-by-step explanation:
Like terms are those terms which have same variable to the same power.
Given the expression:
[tex]\frac{5}{6}a-2b-16.3+\frac{b}{12}+c-0.9b[/tex]
Combine like terms;
[tex]\frac{5}{6}a+b(-2+\frac{1}{12}-0.9}-16.3+c[/tex]
Simplify:
[tex]\frac{5}{6}a-2.81666667b-16.3+c[/tex]
Therefore, the term can be combined in the given expression is,
[tex]-2b[/tex], [tex]\frac{b}{12}[/tex] and [tex]-0.9b[/tex]

Choose the right answer. If the distance on a map from point R to point T measures 3.0 inches and the scale is 1 inch = 0.5 miles, what is the distance in miles from point R to point T? ______ miles
A. 6.0
B. 3.0
C. 1.5
Answer: The distance from point R to point T is 1.5 miles.
Step-by-step explanation:
In the map, the scale is,
1 inches = 0.5 miles,
3 inches = 3 × 0.5 = 1.5 miles,
Thus, in the map 3 inches shows 1.5 miles,
Since, in the map, the distance from point R to point P = 3 inches,
Thus, the actual distance from point R to point P = 1.5 miles.
⇒ Option C is correct.

The angle of depression from the top of a flag stick to a golf ball on the ground is 24 degrees. If the flagstick is 6 feet tall, how far away is the golf ball from the base of the flag stick?
A. 13.5 ft
B. 12.3 ft
C. 9.8 ft
D. 14.6 ft
E. 15.1 ft
Answer:
The Golf ball from the base of the flag stick is 13.5 ft
A is correct.
Step-by-step explanation:
Please see the attachment for figure.
Let AB is height of flag stick. AB=6 ft
BC is distance of golf ball from base of the flag stick.
In ΔABC, ∠B=90°
[tex]\dfrac{AB}{BC}=\tan 24^\circ[/tex]
[tex]\dfrac{6}{BC}=0.4452[/tex]
[tex]BC=13.5[/tex] ft
Hence, The Golf ball from the base of the flag stick is 13.5 ft

Sara has 20 sweets.
12 liquorice, 5 mint, 3 humbug.
Sara is going to take at random two sweets.
work out the probability that the two sweets will not be the same type. Give your answer as a fraction
Answer:
111/190
Step-by-step explanation:i know you dont want to see explanation so yeah...
Probabilities are used to determine the chances of an event.
The probability that the two selected sweet will not be of the same type is [tex]\frac{111}{190}[/tex]
The given parameters are:
[tex]n = 20[/tex] --- number of sweet
[tex]L = 12[/tex]
[tex]M = 5[/tex]
[tex]H = 3[/tex]
First, we calculate the probability that the two selected sweet will be of the same type.
This is calculated as:
[tex]P(Same) =P(L\ and\ L) + P(M\ and\ M) + P(H\ and\ H)[/tex]
Because the selection is without replacement, the equation becomes
[tex]P(Same) = \frac{12 \times 11}{20 \times 19} +\frac{5 \times 4}{20 \times 19} + \frac{3 \times 2}{20 \times 19}[/tex]
[tex]P(Same) = \frac{132}{380} +\frac{20}{380} + \frac{6}{380}[/tex]
Add fractions
[tex]P(Same) = \frac{132+20+6}{380}[/tex]
[tex]P(Same) = \frac{158}{380}[/tex]
Using the complement rule, the probability that the two selected sweet will not be of the same type is:
[tex]P(Not\ same) = 1 - P(Same)[/tex]
This gives
[tex]P(Not\ same) = 1 - \frac{158}{380}[/tex]
Take LCM
[tex]P(Not\ same) = \frac{380 - 158}{380}[/tex]
[tex]P(Not\ same) = \frac{222}{380}[/tex]
Simplify
[tex]P(Not\ same) = \frac{111}{190}[/tex]
Hence, the required probability is: [tex]\frac{111}{190}[/tex]

The percent of the discount in the problem above is 15%. What percent of the original bill is Chumani's bill? How could you solve the problem using this percent?
Chumani's bill represents 85% of the original bill after a 15% discount is applied. The discounted amount can be found by multiplying the original bill by 0.85.
If the discount on an item is 15%, and Chumani is paying after this discount has been applied, we want to find out what percent of the original bill Chumani's bill is. To do this, we subtract the discount rate from 100%. So, 100% - 15% = 85%. Thus, Chumani's bill is 85% of the original bill.
To calculate the discounted bill, you multiply the original bill amount by 0.85 (which represents 85%). If the original bill was, for example, $100, the calculation would be $100 x 0.85 = $85. So, Chumani would pay $85, which is 85% of the original bill amount.
