Each pizza is $13. All you have to do is 48+4=52 and then 52/4 is 13

Round 223 to the nearest 10

zubka84 [21]

220. Think of it this way: 5 and above, give it a shove, 4 and below, keep it down low. That means that if the last number is five or above, push it up to the nearest 10, and if the last number is four or below, round to the lowest 10.

Find m∠A given ΔABC where a=4, b=6, c=3.

igomit [66]

For this question, we're going to use the law of cosines.
The law of cosines is the following equation:

$a^2=b^2+c^2-2(b)(c) \cos(A)$

We know the values of a, b, and c. We want to find the measure of angle A.
$a=4$
$b=6$
$c=3$

Now, plug in these values into the equation.

$4^2=6^2+3^2-2(3)(6) \cos(A)$
$16=45-36 \cos(A)$

Add both sides by $36 \cos(A)$ and subtract both sides by 16

$36 \cos(A)=29$

Divide both sides by 36

$\cos(A)= \dfrac{29}{36}$

Take the inverse cosine, or arc cosine, of both sides.
Using a calculator, you'll get the following result.

$A \approx 36.3^O$

The measure of angle A should be 36.3 degrees. Hope this helps! :)

Can I get some help with this question? Solve 3(x + 2) > x.

Montano1993 [528]

Answer:

$\large\boxed{x>-3\to\{x\ |\ x>-3\}\to x\in(-3,\ \infty)}$

Step-by-step explanation:

$3(x+2)>x\qquad\text{use the distributive property:}\ a(b+c)=ab+ac\\\\(3)(x)+(3)(2)>x\\\\3x+6>x\qquad\text{subtract 6 from both sides}\\\\3x+6-6>x-6\\\\3x>x-6\qquad\text{subtract x from both sides}\\\\3x-x>x-x-6\\\\2x>-6\qquad\text{divide both sides by 2}\\\\\dfrac{2x}{2}>\dfrac{-6}{2}\\\\x>-3$

What is the first step in constructing a circumscribed circle around triangle XYZ? Construct a line parallel to segment YZ. Cons

meriva

Answer:

Construct the perpendicular bisector of segment XY

Step-by-step explanation:

I am pretty sure this is the answer. I assume you r taking flvs just like me. I think this is the answer because to construct a circumscribed circle u will need to draw a perpendicular bisector to the sides of the polygon. Which o think is the first step.
