Answer 1

Answer:

Step-by-step explanation:

R=50+20t, B=150-20t they will be the same height when

50+20t=150-20t

50+40t=150

40t=100

t=2.5, usingvthis value for t in either original equation will give you the height.

h=50+20(2.5)

h=100m

Answer 2

Answer:

it would be 100. they would both meet at 100m

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)*

Answers

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

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)
​

Answers

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

1100

=500.

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

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!

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.

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).
