Answer:
49/12
Step-by-step explanation:
1 ⅓ can be written as 1 + 1/3
1 ⅓
= 1 + 1/3
LCM = 3
= 3/3 + 1/3
= ( 3 + 1 )/3
= 4/3
2 ¾
= 2 + 3/4
LCM = 4
= 8/4 + 3/4
= ( 8 + 3 )/4
= 11/4
1 ⅓ + 2 ¾
= 4/3 + 11/4
LCM = 3 x 4 = 12
4/3 x 4/4
= ( 4 x 4 )/( 3 x 4 )
= 16/12
11/4
= 11/4 x 3/3
= ( 11 x 3 )/( 4 x 3 )
= 33/12
16/12 + 33/12
= ( 16 + 33 )/12
= 49/12

What is the volume of the right prism
A. 1275
B. 600
C. 1020
D. 680
Answer:
B
Step-by-step explanation:
The face of the prism is the right triangle closest to us.
The area of the right triangle is 15 * 8 = 120 / 2 = 60 The general formula for a triangle's area is 1/2 * B * h.
B = 8
h = 15
The volume in general is B*h.
The height in this case is 10 (the height in this case is perpendicular to the surface containing the right triangle).
Volume = B * h
Volume =60 * 10
Volume = 600

Find the value of n x 5 when n=8
Answer:
40
Step-by-step explanation:
Since n=8, then you do 8x5=40.
Answer:
40
Step-by-step explanation:
n x 5
We know what n is equal (8), so we can substitute that number in the given equation.
n x 5 = (8) x 5 = 40
Therefore, the value of n x 5 when n = 8 is 40.

Step-by-step explanation:
Insribed angle is half the measure of intercepted arc.
m∠CAB = 1/2mCDBSince O is the center COB is the diameter of this circle.
The diameter splits the circle into two equal arcs. As the full circle is 360°, each semicircle is 180°.
So
1/2mCDB = 1/2(180°) = 90°And the angle measure is
m∠CAB = 90Proved
Answer:
[tex]\overline{\sf COB}[/tex] is the diameter of circle O.
The angle on a straight line is 180° ⇒ ∠COB = 180°
The angle at the center of a circle is twice the angle at the circumference:
⇒ ∠CAB = 1/2 of ∠COB = 1/2 x 180°
⇒ ∠CAB = 90°
What is the perimeter of this rectangle pls help
Answer:
24
Step-by-step explanation:
Perimeter of a shape = sum of all lengths of sides
⇒ Perimeter of a rectangle = (2 × width) + (2 × length)
From inspection of the rectangle:
width = 4length = 8⇒ Perimeter = (2 × 4) + (2 × 8)
= 8 + 16
= 24

If we look at angle BOD, that would form a right angle (90°), given that one part of that whole angle is 30°, the other would be;
30° + x = 90°
-30 -30
x = 60°, therefore ∠BOC = 60°.
If we take a look at angle EOC, we can see that that angle is a straight angle (180°), we can also see that a right angle (90°) is a part of that angle alongside the angle we just previously found (60°). So all of those angles plus the unknown angle (AOE) which we will consider 'x' summed up would result in 180 degrees.
Now we set up the equation;
90° + 60° + x = 180°
150 + x = 180
-150 -150
x = 30°, therefore ∠AOE = 30°.
16.
The sum of the interior angles in a triangle will always equal 180°. (We can also confirm this using the formula (n - 2) x 180.)
Given two of the angles, we must add them and the unknown angle(D) which we will consider 'x' to make it result in 180°.
Now we set up the equation;
55° + 18° + x = 180°
73 + x = 180
-73 -73
x = 107°, therefore ∠EDF = 107°.
17.
To find angle P, we must first find the supplement of 34° because 34° and the angle beside forms a straight angle (180°).
Set up an equation;
34 + x = 180
-34 -34
x = 146°, now that we've found the supplement, we add this supplement with the other given angle (23°) because all three angles (unknown angle which we will consider x + 23 + 146) will equal 180°(sum of interior angles of triangle).
146° + 23° + x = 180°
169 + x = 180
-169 -169
x = 11°, therefore ∠QPR = 11°.
18.
Seeing that the bigger triangle has a 90° angle (indicated with a square), and two other equal angles(indicated with the two lines on both legs of the big triangle), we solve for those two missing equal angles in the bigger triangle which we will then use to solve for the smaller triangle's angle.
2x + 90° = 180°
-90 -90
2x = 90
/2 /2
x = 45°, so now we know the two angles in the bigger triangle excluding the right angle.
One of those equal angles is vertical to the smaller triangle, and vertical angles are congruent.
Hence, the angle vertical to the bigger triangle in the smaller triangle will be 45°.
Now we solve for ∠CDE.
Add the two angles and the missing angle to equal 180°.
Set up the equation;
86° + 45° + x = 180°
131 + x = 180
-131 -131
x = 49°, so ∠CDE = 49°.
Expand and simplify (x+6)(x−11)
Answer:
x^2 - 5x - 66
Step-by-step explanation:
1. Distrubute the x to the x and -11 so you will get x^2 - 11x
2. Distrubute the 6 to x and -11 and you get 6x - 66
3. Combine like terms (x^2 - 11x + 6x - 66) you will get x^2 - 5x - 66
A beach volleyball court is 9 meters wide and 18 meters long. The rope used for the boundary line costs $1.67 per meter. How much would it cost to buy a new boundary line for the court?
Answer:
$90.18
Step-by-step explanation:
Since there are two long sides and two wide sides, you would double them. Add them together, and multiply by price
9 + 9 = 18
18 + 18 36
18 + 36 = 54
54 x 1.67 = 90.18

Marina is spinning a spinner with 15 equal sectors labeled 1 through 15. What is P(factor of 10)? 115 415 13 23
Answer:
4/15
Step-by-step explanation:
Option B is correct, when Marina is spinning a spinner with 15 equal sectors labeled 1 through 15 then P(factor of 10) is 4/15.
What is Probability?It is a branch of mathematics that deals with the occurrence of a random event.
Given that Marina is spinning a spinner with 15 equal sectors labeled 1 through 15.
We have to find the probability P(factor of 10)
The factors of 10 are 1, 2, 5, and 10.
Out of the 15 sectors, there are four sectors that correspond to the factors of 10 (sectors 1, 2, 5, and 10).
Therefore, the probability of landing on a sector that corresponds to a factor of 10 is:
P(factor of 10) = 4/15
Hence, Option B is correct, when Marina is spinning a spinner with 15 equal sectors labeled 1 through 15 then P(factor of 10) is 4/15.
