Answers
Answer:
A
Step-by-step explanation:
Find AB using the Law of Sine:
[tex] \frac{AB}{sin(C)} = \frac{AC}{sin(B)} [/tex]
Thus:
[tex] \frac{AB}{sin(40)} = \frac{47}{sin(103)} [/tex]
Multiply both sides by sin(40)
[tex] \frac{AB}{sin(40)}*sin(40) = \frac{47}{sin(103)}*sin(40) [/tex]
[tex] AB = \frac{47*Sin(40)}{sin(103)} [/tex]
AB = 31.0056916 ≈ 31.0 cm (nearest tenth)

A new car is purchased for $40,000 and over time its value depreciates by one half
every 3 years. What is the value of the car 17 years after it was purchased, to the
nearest hundred dollars?
Answers
9514 1404 393
Answer:
$800
Step-by-step explanation:
The value formula can be written ...
y = 40,000(1/2)^(t/3)
Using t=17, this becomes ...
y = 40,000(1/2)^(17/3) ≈ 800
The value of the car after 17 years is about $800.

A motorcar is running at the rate of 66 km per hour. Each
of its wheels makes 500 revolutions per minute. Find the
radius of the wheel.

Given:
The radius of a wheel =r=35 cm=0.35 cm.
The speed it must keep =s=66 km/h=

To find out:
The number of revolution =n, it makes per minute to maintain that speed.
Solution:
The circumference =C of the wheel =2πr=2×

×0.35 m=2.2 m=C
The distance the wheel covers in 1 min=d=1100 m.
Now the distance =d covered by a wheel in one revolution = the circumference of the wheel.
∴ Here the number of revolution =n=

WILL GIVE BRAINLIEST Which of the following describes the quotient of 3 and -30?
A.
The quotient is an irrational number.
B.
The quotient is a rational number.
C.
The quotient is undefined.
D.
The quotient is an integer
Answers
Answer:
if i am correct the answer is A
Step-by-step explanation:
The quotient of 3 and -30 is a rational number. The correct answer would be an option (B).
What is the Quotient?A quotient is defined as the outcome of dividing an integer by any divisor that can be said to be a quotient. The dividend contains the divisor a specific number of times.
The quotient of 3 and -30 is:
3 ÷ (-30) = -0.1
Therefore, the quotient is a rational number. Option B is correct.
A rational number is a number that can be expressed as a ratio of two integers, where the denominator is not zero. In this case, -0.1 can be expressed as the ratio of the integer -1 and the integer 10, where the denominator 10 is not zero.
Note that the quotient is negative because we are dividing a positive number (3) by a negative number (-30).

dollars to Guatemalan quetzals is 1:8.5135. how much money does Charles have, as measured in quetzals? Round
your answer to two decimal places.
3,533.10 quetzals
b. 2,131.02 quetzals
768.31 quetzals
d. 48.75 quetzals
Answers
Answer:
A
Step-by-step explanation:
Charles have 3533.10 quetzals.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Examples:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
We have,
Charles allocated amount for spending = $415.
The exchange rate from US dollars to Guatemalan quetzals.
= 1 : 8.5135
This means,
$1 = 8.5135 quetzals
Now,
$1 = 8.5135 quetzals
Multiplying 415 on both sides.
$415 = 415 x 8.5135
$415 = 3533.1025 quetzals
Rounding to two decimal places.
$415 = 3533.10 quetzals.
Thus,
Charles has 3533.10 quetzals.

What are rational and irrational numbers and how are radicals related to rational exponents?
Answers
A rational numbers is any number that can be turned into a fraction/ratio. (Ex. 8, 0.75, 1/3). An irrational number is anything that can't be turned into a fraction/ratio. (Ex. Pi, square root of 2). Radicals and rational exponents are related because radicals can be converted into rational exponents.
Answer:
Any number that can be written as a fraction with integers is called a rational number. An irrational number is a number that cannot be expressed as a fraction for any integers. Radicals are related because for irrational numbers they cannot be simplified under the radical and you use a radical on the exponent to cancel it out, hope this helps!
