A cone has a diameter of 22 inches and a height of 15 in. What is the volume
of the cone? (Use 3.14 as an approximation of)*
Answer:
1899.7 in^3.
Step-by-step explanation:
Radius = 1/2 diameter
= 22 * 1/2 = 11.
Volume = 1/3 pi r^2 h, so
= 1/3 * 3.14 *1 1^2 *1 5
= 1899.7 in^3.

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
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).

Write an equation for (-1,-2),(-3,-4)
Answer:
y=x+1
Step-by-step explanation:
First find the slope by subtracting the y values from both points and dividing it by the subtraction of the x values from both points:
-4--2/ -3--1= -2/-2= 1
so the slope is 1
Now find the y-intercept by plugging in the x and y from one of the points into the equation y=x+b
-3=-4+b
1=b
now plug the slope and y intercept in:
y=x+1

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.
.(Ans: 35 cm)
Answer:
Given:
The radius of a wheel =r=35 cm=0.35 cm.
The speed it must keep =s=66 km/h=
60
66×1000
m/min=1100 m/min
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×
7
22
×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=
C
d
=
2.2

Charles is planning a trip to Guatemala. He has allocated $415 for spending money. If the exchange rate from US
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
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.
