Answer:
7/20
Step-by-step explanation:
Let the total probability be 1;
Given
Probability of selecting a red M&M = 2/5,
Probability of selecting a green M&M = 1/4
Required
Probability of selecting a white M&M
Probability of selecting a white M&M = 1 - (2/5+1/4)
Probability of selecting a green M&M = 1 - (4(2)+5(1)/20)
Probability of selecting a green M&M = 1 - (8+5/20)
Probability of selecting a green M&M = 1 - 13/20
Probability of selecting a green M&M = 7/20
hence the Probability of selecting a green M&M is 7/20

Answer:
Step-by-step explanation:
This looked very difficult UNTIL I looked at the pyramid as ONE HALF of a larger pyramid! Image a mirror image of the pyramid creating a pyramid that is 12 cm of the front and back side and 6 cm on the left and right edge.
IT IS NO LONGER A SQUARE PYAMID so you need the volume for a rectanglar pyramid
The volume of a square pyramide is .....
V = side² × (height / 3)
The volume of a rectangular pyramide is .....
V = base area × (height / 3)
= length × width × (height / 3)
= 12 × 6 × 10 / 3 cm³ BUT REMEMBER we want only HALF of the
= [12 × 3 × 10] divide by 2 cm³ Rectangular pyamid
Volume of the image shown in the diagram is ....
= 360 / 2 cm³
= 180 cm³ <----------------- Final Answer

Find the circumference of a circle that has an area of 153.86 cm.
Answer:
C=[tex]14\pi[/tex] or ≈43.96cm
Step-by-step explanation:
Start by figuring out the Area of the circle to get the radius (r)
Area (A)=153.86 cm
A=[tex]\pi r[/tex]²
153.86=[tex]\pi[/tex]r²
153.86÷[tex]\pi[/tex]=r²
49=r²
√49= r
r= 7cm
Next insert r=7cm into the Circumference equation of a circle
C=2[tex]\pi[/tex]r
C= 2×[tex]\pi[/tex]×7
C=14[tex]\pi[/tex] or C=43.96cm
A television screen, length is 16 1/2 inches, width is w inches, and area is 462 square inches. Select all THREE equations that represent the relationship of the length, width, and area of the television.
Answer:
it's B, C, and D
Step-by-step explanation:
A. w ⋅ 462 = 16 1/2
not A
w * a ≠ l
B. 16 1/2 ⋅ w = 462
is B
l * w = a
C. 462 ÷ 16 1/2 = w
is C
a / l = w
D. 462 ÷ w = 16 1/2
is D
a / w = l
E. 16 1/2 ⋅ 462 = w
not E
l * a ≠ w

Answer:
A = 20°
AC = 6.6
BC = 2.4
Step-by-step explanation:
Given:
B = 70°
C = right angle = 90°
AB = 7
Required:
A, AC, and BC
Solution:
✔️A = 180 - (90 + 70) (sum of triangle)
A = 20°
✔️Use trigonometric function to find AC:
Refernce angle = 70°
Opp = AC
Hypotenuse = 7
Apply SOH,
sin 70 = Opp/Hyp
sin 70 = AC/7
7 * sin 70 = AC
6.57784835 = AC
AC = 6.6 (nearest tenth)
✔️Use trigonometric function to find Bc:
Refernce angle = 70°
Adj = BC
Hypotenuse = 7
Apply CAH,
cos 70 = Adj/Hyp
cos 70 = BC/7
7 * cos 70 = BC
2.394141 = BC
BC = 2.4 (nearest tenth)

Answer:

Step-by-step explanation:
Alright so we just need to find the percentage values of the discount and tax
What is 10%?:
x/800 = 10/100
8000 = 100x
x = 80
800 - 10%
800 - 80 = 720
What is 8%?:
x/800 = 8/100
6400 = 100x
x = 64
720 + 8%
720 - 64 = 784

if the two adjacent angles are supplementary then their outer sides are???
Answer:
If the bisectors of two adjacent angles are perpendicular to each other, are the angles then supplementary angles?
Suppose two angles ABC and CBD are x and y.
x+y = 180 deg.
The bisector of angle ABC (BE) and the bisector of angle CBD (CF) will form angle EBF = (x/2)+(y/2) = 180/2 = 90 deg.
Conclusion: If the angle bisectors of two adjacent angles are perpendicular to eaxh other, the adjacent angles are supplementary angle
Adjacent angles are when the 2 angles have a common vertex and a common arm.
if the exterior sides of 2 adjacent angles are perpendicular, then the angles are complementary angles.
Then the sum of the 2 adjacent angles is a right angle - 90°.
When 2 angles add up to 90°, they are called a pair of complementary angles.
Step-by-step explanation:

Thomas drew a triangle which has one angle that measures more than
90° and two angles that each measure less than 90°. What kind of
triangle did he draw?
Answer:
obtuse triangle
Step-by-step explanation:
it is obtuse because it needs to have all 3 sides to be acute to be an acute angle and it doesn't have any 90° angles so it has to be obtuse. Also because to be an obtuse it has to have 2 acute angles and 1 obtuse angle. Hope this helps!!

Determine the number of terms n :
a 1 = 15, a n = 79, S n = 423
Answer:
The number of terms in the sequence is 9
Step-by-step explanation:
We want to get the number of terms
Mathematically, we have the formula for the sum of terms in an arithmetic sequence as
[tex]sn = \frac{n}{2} (a + 1)[/tex]
a represents the first terms, and i represent the last term
[tex]423 = \frac{n}{2} (15 + 79) \\ \\ 423 \times 2 = 94(n) \\ \\ 94n = 846 \\ \\ n = \frac{846}{94} \\ \\ n = 9[/tex]

Which situation is best represented by the equation y=5x + 10?
Answer:
x=1/5y-2
Step-by-step explanation:
Step 1: Flip the equation
5x+10=y
Step 2: Add -10 to both sides
5x+10+-10=y+-10
5x=y-10
Step 3: Divide both sides by 5.
5x/5 =y-10/5
x=1/5y-2

Solving systems of equations by graphing. how do you do this
Answer:
Solve systems of equations by graphing
A system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.
Example
[tex]\left \{ {{y=2x+2} \atop {y=x-1}} \right.[/tex]
Graph the equations in a coordinate plane
The two lines intersect in (-3, -4) which is the solution to this system of equations.
