Answer:
In the first box: 24a
In the second box: +12
In the third box: 24a + 12
Step-by-step explanation:
For the first box, you're multiplying 3 times 8a. Since we don't know a, we leave it alone and just multiply the number next to it. So 3 x 8 = 24...3 x 8a = 24a
3 times a positive 4 is a positive 12 (this is kind of a weird way to write it, but area models are weird, imo.
It's just trying to show that you multiply the 3 by every part of what's inside the parentheses.

The radius of a baseball is about 9.25 inches. The radius of the Basketball is 9.55 inches. What is the
difference of the volumes between the basketball and baseball?
331.55
2734.89
333.14
364.52
Answers
Answer:
C. 333.14
Step-by-step explanation:
Both the basketball and baseball has got the shape of a sphere. So that;
volume of a sphere = [tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]
where r is the radius
i. Volume of the baseball = [tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]
= [tex]\frac{4}{3}[/tex] x [tex]\frac{22}{7}[/tex] x [tex](9.25)^{3}[/tex]
= 3315.5655
volume of the baseball = 3316.57 cube inches
ii. Volume of the basketball = [tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]
= [tex]\frac{4}{3}[/tex] x [tex]\frac{22}{7}[/tex] x [tex](9.55)^{3}[/tex]
= 3649.8372
Volume of the basketball = 3649.84 cube inches
The required difference = volume of basketball - volume of baseball
= 3649.84 - 3316.57
= 333.27 cube inches
The difference of the volumes of the basketball and baseball is 333.27 cube inches.

(450) + (28.75x) = 967.50
solve for x
Answers
Answer:
18
Step-by-step explanation:
Hello,
In order to solve for x, we need to isolate the variable on one side of the equation.
To do this, we subtract 450 from both sides of the equation, and this will give you:
28.75x = 517.5
As mentioned, we need to isolate x, so we divide both sides by 28.75. This will give the following.
x = 18

What is (-m)⁻³n if m = 2 and n = -24?
Answers
Answer:
-3
Step-by-step explanation:
(-2)^-3 x (-24)
(-2)^3 becomes 1/(-2)^3 in order to make the negative exponent a positive one.
then, you do 1/-8 (the -8 is the (-2)^3 simplified) x -24
1/-8 x (24) = 24/-8 = -3.

Answers
Answer:
s = 4.5 cm
l= 3.75 cm
Step-by-step explanation:
Mathematically, when two shapes are similar, the ratio of their corresponding sides are equal
According to this rule, we have it that;
4/6 = 3/s
4 * s = 3 * 6
4s = 18
s = 18/4
s = 4.5 cm
Similarly;
4/5 = 3/l
4 * l = 5 * 3
4l = 15
l = 15/4
l = 3.75 cm

If the measure of arc KM is 112°, find the measure of arc LM
Answers
All circles are equal to 380 degrees
You’re alr told that a part of the circle is equal to 112
So you subtract 360-112 which is 248
This means that the rest of the circle (without the zone that KM covers) is 248
As you can see both sides (ML and KL) are equal because they have congruency lines
So both sides have the exact same length
If what’s remaining is 248 and there are 2 equal sides you just have to divide
248/2 and that is 124
