One friend solves
7(x + 4) = 49 by dividing each side
by 7 and then subtracting 4 from
each side. Another friend solves it by
first distributing the 7 on the left side
of the equation, then subtracting 28
from each side, and finally dividing
each side by 7. Which friend uses the
correct method? Explain.
Answers
Answer:
the second friend
Step-by-step explanation:
Answer:
both methods are correct
Step-by-step explanation:
Given
7(x + 4) = 49 ( divide both sides by 7 )
x + 4 = 7 ( subtract 4 from both sides )
x = 3
---------------------------------------------------------
Given
7(x + 4) = 49 ← distribute parenthesis by 7
7x + 28 = 49 ( subtract 28 from both sides )
7x = 21 ( divide both sides by 7 )
x = 3
As shown both methods are equally valid
The cylinder and the sphere below have the same radius and the same volume. What is the height of the cylinder?
Answers
Answer:
Height of cylinder (h) = (4/3)R
Step-by-step explanation:
Given:
Radius of cylinder (r1) = R

Radius of sphere (r2) = R
Volume of cylinder = volume of sphere
Find:
Height of cylinder (h) = H = ?
Computation:
[tex]Volume\ of\ cylinder = volume\ of\ sphere\\\\ \pi (r1)^2h =\frac{4}{3} \pi (r2)^3\\\\\pi (R)^2h =\frac{4}{3} \pi (R)^3\\\\ h=\frac{4}{3} (R)[/tex]

Andrea has 3 tiles.
One is a regular octagon, one is a regular pentagon
and one is a regular hexagon.
Andrea thinks the 3 tiles will fit together perfectly,
as shown in the diagram.
Show calculations to prove that she is wrong.
Answers
You then times this number by 180 to get the sum of interior angles for that shape
Let’s start with the octagon
It has 8 sides so you need to do 6*180 which gives you 1080
You divide this by 8 which gives you 135
This is one angle in the octagon
If you do this for all of the shapes you get 135, 108 and 120 degrees
If you add these all up you get 363 which is 3 degrees off of 360 which would be a perfect fit
Andrea is incorrect. Given 3 tiles will not fit together perfectly.
Angles formed at a point: Sum of all angles around a point is 360°.
As shown in the picture,
If the tiles join perfectly at a point, sum of all angles around the joining point should be 360°.
Expression for the measure of the interior angle of a polygon,
Interior angle of a polygon = [tex]\frac{(n-2)\times 180^\circ}{n}[/tex]
Interior angle of a pentagon = [tex]\frac{(5-2)\times 180^\circ}{5}=108^\circ[/tex]
Interior angle of a hexagon = [tex]\frac{(6-2)\times 180^\circ}{6}=120^\circ[/tex]
Interior angle of an octagon = [tex]\frac{(8-2)\times 180^\circ}{8}=135^\circ[/tex]
To prove that the given tiles fit together perfectly → Sum of all the angles around the common point should be 360°
Sum of all interior angles = 108° + 120° + 135°
= 363°
Therefore, given tiles will not fit together perfectly.

For the first statement, we need to find the percentages of sold hats. The percentage of white hats sold was (120/200) * 100 = 60% and the percentage of black hats sold was (210/300) * 100 = 70%. The first statement is "The musical group sold 60% of the white hats and 70% of the black hats."
The second statement asks us to compare the 2 percentages, and since 70% > 60%, the statement would be "A greater percentage of black hats were sold." Hope this helps!

which is a solution to the systen of equations. x+3y=18. x+2y=14 A) 6,4 B) 4,6 C) 6,-4 D) -4,6
Answers
Step-by-step explanation:
• Elimination (find y) :
x + 3y = 18
x + 2y = 14 _
y = 4
• Substitute y = 4 to one equation :
x + 3y = 18
x + 3(4) = 18
x + 12 = 18
x = 18 - 12
x = 6
• The set of equations :
{x, y} = {6, 4}
So, the solution to that system equation is 6, 4 (A)

In a football drill, Ron is standing 30 yards directly east of John, and Bill is standing 40 yards directly north of John. If the football is thrown from Ron to Bill and then from Bill to John, how many yards did the football travel?
Answers
Answer:
D, 90
Step-by-step explanation:
See image below.
To find the distance from Bill to Ron, we will use the Pythagorean Theorem, which is a^2+b^2=c^2.
(a and b being the legs of the triangle, they form the 90 degree angle. c=hypotenuse, or the side that is opposite from the 90 degree angle)
In this example, a=30 and b=40.
30^2+40^2=c^2
900+1600=c^2
2500=c^2
c=50.
Then, to find the yards thrown, we will add the distance from Ron to Bill and the distance from Bill to John. This can be written as 50+40, which equals 90 yards.

Suppose that the functions r and s are defined for all real numbers x as follows.
r(x) = x + 5
s(x) = 3x + 1
Write the expressions for (r * s)(x) and (r + s)(x) and (r - s)(4) evaluate .
Answers
Answer:r*s = 168
Step-by-step explanation: (2x-1)(6x) = 12 x^2 - 6x
r(s(x)) = 2 (6x) - 1 = 12 x - 1
r(x) - s(x) = (2x-1) - 6x = -4x -1
r(x) = s(x) when 2x-1 = 6x or x = -1/4
r(4) = s(4) never
(r*s)(4) = 12 x^2 - 6 x = 12*16 - 24 =168

Answers
Answer:

Step-by-step explanation:
To get the mean, we must add all the numbers then divide by the amount of numbers there were.
42 + 45 + 58 + 63 + 52 + 42 + 47 = 349
Since we have 7 numbers we can do
349/7 ~ 49.9
Answer: 49.8 (50 if rounded to the nearest ones place)
Step-by-step explanation: First, let's put the number from greatest to least...and we also have to add all the numbers...
42 + 42 + 45 + 47 + 52 + 58 + 63 = 349
Lastly, we have to divide the total by how many numbers there are on the data set...there's 7
349 ÷ 7 = 49.8 (50 if rounded to the nearest ones place)
Therefore, the mean is 49.8 or 50, I hope this helps!
