<u><em>Answer: B. m=-23 and -23=m. *The answer should be the negative sign.*</em></u>

Step-by-step explanation:

addition property of equality is adding the same number to both sides of an equation does not change the equation.

a+c=b+c

add by 10 both sides of equation.

m-10+10=-33+10

simplify.

33-10=23

23+10=33

33-23=10

m=-23

It changes positive to negative.

Hope this helps!

Thanks!

Have a great day!

A box of cereal states that there are 75 calories in a 34-cup serving. What is the unit rate for calories per cup? How many calo

xeze [42]

The unit rate is how many calories are in 1 cup of cereal.
Set up a proportion:
$\frac{75 cal}{3/4 cup} = \frac{X cal}{1 cup}$
Cross multiply and solve:
$\frac{3}{4} X = 75\\ 3X=300\\X=100$
There are 100 calories per cup of cereal.

To get the calories in 4 cups of cereal, simply multiply the unit rate of 100cals/cup by 4.
$100*4=400$
There are 400 calories in 4 cups of cereal.

Can the sides of a triangle have lengths 3, 3, and 10?

Bingel [31]

Answer:

Step-by-step explanation:

According to the property of the triangle ,

sum of any two sides should we greater then third side of the triangle.

Here, Measurement of three sides are given as 3,3,5 .

So, sum of the measurement of first two sides is 6.

And third side equals 10.

Clearly 6 is less than 10. So . it violates the property sum of any two sides should we greater then third side of the triangle.

Thus , Sides of a triangle can't be 3,3,10.

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER

Step2247 [10]

Answer:

$A = 297\pi$

Step-by-step explanation:

To solve this problem we need to be familiar with the formula for the surface area of a cone:

$A = \pi r(r + \sqrt{h^2+r^2})$

We are given the length of a side and the diameter, to calculate the radius divide the diameter in half:

$r = \frac{d}{2}\\r = \frac{18}{2}\\r = 9 cm$

To calculate the height of the cone, we must use the Pythagorean Theorem:

$C^2 = A^2 + B^2$

We can treat the side length as the hypotenuse $C$ , the radius as the base $A$ , and solve for height $B$ . Set the expression up like this:

$C^2 = A^2 + B^2\\24^2 = 9^2 + B^2\\B^2 = 24^2 - 9^2\\B = \sqrt{24^2 - 9^2}\\B = \sqrt{576 - 81}\\B = \sqrt{495}\\B \approx 22.25$

Now we can plug into our original formula:

$A = \pi r(r + \sqrt{h^2+r^2})\\A = \pi 9(9+\sqrt{\sqrt{495}^2+9^2}\\A = \pi 9(9+\sqrt{495 + 81}\\A = \pi 9(9+\sqrt{576})\\A = \pi 9(9 + 24)\\A = \pi 9(33)\\A = 297\pi$
