Determine where to place the decimal point in the dividend and divisor so that the quotient is between 23 and 25

timama [110]

Answer:

Place the decimal before the last digit in both number i.e. 1602.3 and 65.4

Step-by-step explanation:

We are given the numerical expression 16023÷654.

Here, we have,

Dividend = 16023

Divisor = 654

it is required that the quotient of the division to be between 23 and 25.

If we take the numbers,

1602.3 and 65.4

This gives us,

$\frac{1602.3}{65.4}=24.5$ .

Hence, placing the decimal before the last digit in both number will give the desired result.

Please help i will give brainliest

Answer:

Step-by-step explanation:

Take the area of the yard and subtract from it the area of the pool. In quadratic form, the area of the pool is

$2x^2-x-28$

Subtracting the area of the pool from the area of the yard:

$3x^2-14x-5-(2x^2-x-28)$

Since the negative in front of the parenthesis will change the signs inside:

$3x^2-14x-5-2x^2+x+28$

Combine like terms to get the area left after the pool goes in:

$x^2-13x+23$

Mike had a jar of nickels that had five more nickels than he originally thought. If the total amount of nickels was $4.35, how m

aivan3 [116]

A nickel is worth 5 cents. So if he has 5 nickels extra. They are worth 25 cents. Subtract 0.25 from 4.35 and you get 4.10. Now all you have to do is divide 4.10 by 0.05, which is a nickel. The answer is "Mike thought he had 82 nickels"

What is the radian measure of the central angle of a circle of radius 1.5 meter that intercepts an arc of length 600 centimeters

Maksim231197 [3]

Radian measure of the central angle is 4 radian

Solution:

Given that,

A circle of radius 1.5 meter that intercepts an arc of length 600 centimeters

To find: Radian measure of the central angle

Let us find the circumference of circle

The circumference of circle is given as:

$\text{ circumference of circle } = 2 \pi r$

Where "r" is the radius of circle

$\text{ circumference of circle } = 2 \times \pi \times 1.5 = 3 \pi$

Therefore circumference of circle = $3 \pi$ meters , which subtends central angle of $2 \pi$ radian

Given that arc of length 600 centimeters. Let us convert 600 centimeter to meter

We know that, to convert centimeter to meter divide the length value by 100

$\text{ 600 centimeter } = \frac{600}{100} \text{ meter } = 6 \text{ meter}$

Therefore arc of 6 meter will subtend a central angle of:

$\rightarrow \frac{6}{3 \pi} \times 2 \pi = 4$

Therefore radian measure of the central angle is 4 radian
