Answers

Answer 1

Answer:

Step-by-step explanation:

3x^2 + 8x - 16 - SOMETHING = x^2 - 4

Re-arranging left and right:

SOMETHING = 3x^2 + 8x - 16 - x^2 + 4

= (3x^2 - x^2) + 8x - 16 + 4

= 2x^2 + 8x - 12

Answer 2

Answer:

Original expression:  [tex]3x^2+8x-16[/tex]

Let [tex]a[/tex] be the quantity Amir subtracted from the original expression.

Expression after subtraction: [tex]x^2-4[/tex]

[tex]\implies (3x^2+8x-16)-a=x^2-4[/tex]

Solve for [tex]a[/tex]:

[tex]\implies 3x^2+8x-16-a=x^2-4[/tex]

Add 4 to both sides:

[tex]\implies 3x^2+8x-12-a=x^2[/tex]

Subtract [tex]x^2[/tex] from both sides:

[tex]\implies 2x^2+8x-12-a=0[/tex]

Add [tex]a[/tex] to both sides:

[tex]\implies 2x^2+8x-12=a[/tex]

Therefore, Amir subtracted [tex]2x^2+8x-12[/tex] from the original expression.

Now that we have common denominators we can compare both fractions and say that the one with the higher denominator is larger, Hence=

[tex] \frac{4}{5} > \frac{3}{5} [/tex]

[tex] \frac{4}{5} > 0.6[/tex]

Answer:

Step-by-step explanation:

Given into Decimal:

4/5 = 0.8

Thus, 0.8 > 0.6

Hence, Answer = 4/5 > 0.6

Is the area of a square with side length 2 inches greater than or less than the area of a circle with radius 1.2 inches?

Answers

Answer:

  less

Step-by-step explanation:

We can answer the question about relative sizes of a square and a circle by finding the area of each.

__

The area of the square is ...

  A = s²

  A = (2 in)² = 4 in²

The area of the circle is ...

  A = πr²

  A = π(1.2 in)² = 1.44π in² ≈ 4.524 in²

The area of the square is less than the area of the circle.

_____

Additional comment

The area of a circle is π/4 times the area of the square in which it is inscribed. If the diameter of the circle is 1.2 times the side length of the square, its area ratio to the square will be (1.2²)(π/4) = 0.36π ≈ 1.13. That is, the circle is larger and the square is smaller.

The graph shows the distance covered by a runner after a given number of hours.

The runner travels
✔ 8
miles in 2 hours.
The runner’s speed is
miles per hour

Answers

The runners speed is 4 miles per hour

If the runner travels 8 miles in 2 hours then the speed of the runner is 4 miles per hour.

The runner traveled 8 miles in 2 hours.

To find the runner's speed, we can use the formula:

Speed (in miles per hour) = Distance / Time

In this case, the distance is 8 miles and the time is 2 hours:

Speed = 8 miles / 2 hours

= 4 miles per hour

So, the runner's speed is 4 miles per hour which means that the runner covers a distance of 4 miles for every hour they run.

What is Y + 4 = -3 (x +1) in standard form?

Answers

Answer:
-3x - y = 7

Explanation:
the standard form of an equation is written as Ax + By = C, where A, B, and C are integers.
first, distribute -3:
y + 4 = -3x - 3
then get x and y on the same side and the number on the other side for standard form.
add 3 to both sides:
y + 7 = -3x
subtract y from both sides:
7 = -3x - y

Answer:

-3x - y = 7

first, distribute -3:

y + 4 = -3x - 3

then get x and y on the same side and the number on the other side for standard form.

add 3 to both sides:

y + 7 = -3x

subtract y from both sides:

7 = -3x - y

There are 10 pink balls out of 20. (add all the numbers together)

So that means there is a 10/20 chance to get a pink ball.

Answer:

[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

So, the probability is the number of favored outcomes/ number of possible outcomes.

In this case, the favored outcomes is pink, which is 10.

The number of possible outcomes is 2+1+10+2+5 = 20

This gives us 10/20, which is 1/2 when simplified

By using the first two points on the graph, we conclude that exponential equation is:

y = 200*(0.4)^t

What is the equation?

We assume that the equation is an exponential decay of the form:

y = A*(r)^t

When t = 0 we have:

y = A

On the graph we can see that the initial value is 200, then A = 200, so we have:

y = 200*(r)^t

By looking at the graph we can see that:

80 = 200*(r)^1    (this is the second point graphed).

Solving for r we get:

80 = 200*(r)

80/200 = r = 0.4

Then the exponential equation is:

y = 200*(0.4)^t

Step-by-step explanation:

since we know that when 20 minutes have passed, the minute hand will have moved 4 intervals (i.e. from 12 to 4), and each interval is 30 degrees by measurement. So 4 intervals have a degree measurement of 120 degrees, which is 1/3 of the whole circle (clock). since there isn't any notation on whether pi is taken as 3.14 or 22/7 or whatsoever, you can just say that it has moved (5x2)pi x 1/3 = 3 1/3 pi inches
