Answer:

x = ± $\sqrt{3}$

Step-by-step explanation:

Given

3x² - 9 = 0 ( add 9 to both sides )

Find the exact values for the lengths of the labeled segments a, b and p drawn in green, red, and blue, respectively. Note that

ale4655 [162]

It's pretty tough to do anything with this question when there are
no labels, no segments, no green, no red, no blue, no circle, no arc,
and no indicated point. Was there some more that was supposed to
go along with it, like maybe perhaps possibly a drawing or a picture
of some sort ?

What is the equation of the line that passes through the point(7,-3) And has an undefined slope?

alina1380 [7]

y=0x-3 because the slope is undefined, so it is 0 and the y intercept is -3 because it goes across the y axis.

Sienna has 5 3/4 pounds of grapes. She eats 1/8 pound and gives 2 1/2 pounds to her brother. How many pounds of grapes does Sien

miskamm [114]

The pounds of grapes left with seinna is 3.125 or $\frac{25}{8}$ pounds

<h3>Solution:</h3>

Given that Sienna has $5\frac{3}{4}$ pounds of grapes

She eats $\frac{1}{8}$ pound and gives $2\frac{1}{2}$ pounds to her brother

To find: pounds of grapes left with seinna

We can find the pounds of grapes left with seinna by subtracting the pounds of grapes she ate and pounds of grapes she gave to brother from the total pounds of grapes she had

Pounds of grapes left with seinna = total pounds of grapes - pounds of grapes she ate - pounds of grapes she gave to brother

$\text {total pounds of grapes }=5 \frac{3}{4}=\frac{4 \times 5+3}{4}=\frac{23}{4}$

$\text {pounds of grapes she ate }=\frac{1}{8}$

$\text {pounds of grapes she gave to brother }=2 \frac{1}{2}=\frac{2 \times 2+1}{2}=\frac{5}{2}$

Substituting the values we get,

$\text {Pounds of grapes left with seinna }=\frac{23}{4}-\frac{1}{8}-\frac{5}{2}$

$\text { Pounds of grapes left with seinna }=5.75-0.125-2.5=3.125$

Thus the pounds of grapes left with seinna is 3.125 or $\frac{25}{8}$ pounds

The means and mean absolute deviations of the amount of rain that fell each day in a local city, last week and this week, are sh

laila [671]

Given:
Last Week This Week
Mean 3.5 in. 2.7 in.
Mean Absolute Deviation 1.2 in. 0.5 in

If this is what the table looks like, my answer is (C) 0.8/0.5

The difference of the two means to this week’s mean absolute deviation is?

The two means are 3.5 in and 2.7 in. The difference would be 3.5 - 2.7 = 0.8
This weeks' mean absolute deviation is 0.5 in according to the table.

So, 0.8 / 0.5 is the answer.
