0.985 rounded to the nearest tenth

1 answer:

8 0

They always try to trick you with this. Remember anything 5 or above would round up, anything 4 and under would round down. So look for the tenth place. that's the 9. The number to the right is 8 which is greater than 5. That means round up. You can't round it to 0.1 because that takes it back down. So you just move it over. The answer is 1.0.

What is the area of a sector when theta = 15º and r = 4

Afina-wow [57]

Answer:

2.09 sq. units

Step-by-step explanation:

We can simply use the formula for area of a sector of a circle.

Area of sector = $\frac{\theta}{360}*\pi r^2$

Where $\theta$ is the angle and r is the radius.

It is given that the angle is 15 and radius is 4. We plug them in and find the area:

$\frac{\theta}{360}*\pi r^2\\=\frac{15}{360}*\pi (4)^2\\=\frac{1}{24}*16\pi\\=2.09$

Thus area of sector is 2.09 sq. units.

For the following system of equations, what is the x-value of the solution?

lesantik [10]

Answer:

x = 0

Step-by-step explanation:

Multiply the first equation by -3 and add the second equation.

-3(-x +2y) +(6y) = -3(6) +(x +18)

3x -6y +6y = -18 +x +18 . . . . eliminate parentheses

3x = x . . . . . . . . .simplify

2x = 0 . . . . . . . . subtract x

x = 0 . . . . . . . . . .divide by 2

1. In some music, a whole note equals one measure, a quarter note

Ipatiy [6.2K]

Answer:

3 eighths are needes to make up the rest of the measure.

Step-by-step explanation:

1/4 + 1/4 + 1/ 8 + x = 1

2/4 + 1/8+x=1

4/8 + 1/8+x=1

5/8 + x=1

x=1 - 5/8

x=3/8

We need three eights.(Because 3/8=1/8+1/8+1/8 and 1/8 represents an eights)

Negative 820 square root

erma4kov [3.2K]

A negative number doesn't have a square root...
only one number has to be negative not both...
and 820 doesn't have a perfect square root...
it would be 28.635...
