If you spin the spinner, what is the probability it will stop on a multiple of 3? 1/4, 1/2, 3/20, 3/10.​

A two column proof for ΔAEC ≅ ΔDEB  is as shown below.

"Two triangles are congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure."

"These angles formed on the inside of two straight lines when crossed by a transversal."

"It is point which divides a line segment into two equal parts."

"AAS (Angle Angle Side) theorem states that in the two triangles, if two angles and one side of a triangle are congruent to two angles and one side of a second triangle, then the two triangles are congruent."

For given question,

Given that CA is parallel to DB and E is the midpoint of AD.

CA is parallel to DB

CB is transversal.

∠ACB and ∠CBD are alternate interior angles.

We know that when a transversal intersects a parallel line then alternate interior angles formed are congruent.

So, ∠ACB ≅ ∠CBD                       ................(i)

Similarly for CA || DB and AD is transversal.

∠CAD ≅ ∠ADB                             ..................(ii)

Also,  E is the midpoint of AD.

By definition of midpoint,

⇒ AE = ED                                      ..................(iii)

From (i), (ii) and (iii),

By AAS postulate of triangle congruence,

ΔAEC ≅ ΔDEB      

Therefore, a two column proof for ΔAEC ≅ ΔDEB  is as shown below.

Answer:

The probability that exactly 1 of the next 2 meals is overcooked = 3.34%

Step-by-step explanation:

The probability that a meal at a restaurant is overcooked is 10%

The probability that exactly 1 of the next 2 meals is overcooked = out of 3  meals 1 meal is overcooked of 10%

= 1 × 3 × 10%

= 10 × 3 %

= 3.34 %

Answer: 18.1%

Step-by-step explanation:

[tex]P($ overcooked $)=1 / 10$ \\$P($ exactly one overcooked of next two)\\\begin{$aligned}&\Rightarrow O N+N O \quad\left[\begin{array}{l}O \rightarrow \text { Overcooked } \\N \rightarrow \text { Not Overcooked}\end{array}\right. \\&\Rightarrow P(O) \cdot P(N)+P(N) P(O)\end{aligned}$$[/tex]

Answer:

Area of the shaded polygon= 372

Step-by-step explanation:

The centroid O cuts every median in the ratio 2:1. The distance between a vertex and the centroid is twice the distance between the centroid and the midpoint of the opposite side.

Therefore: |OB| = 2|OF|

|BF| = |OF| + |OB| = |OF| + 2|OF| = 3|OF|

Answer:

base(b)=10 and height(h)=6

Step-by-step explanation:

From the question,

base(b)=x feet

height(h)=(x-4) feet

Area(A)=30 square feet

Now,

We know,

Area of triangle(A)=1/2*b*h

or, 30=1/2*x*(x - 4)

or, 30=1/2*x^2 -4x

or, 30*2=x^2 -4x

or, 60=x^2 -4x

or, 0 = x^2 -4x -60

or, 0 = x^2 +6x - 10x -60

or, 0 = x(x + 6) -10(x + 6)

or, 0 = (x+6) (x-10)

Either,

x+6=0. or, x-10=0

or,x= -6. or, x= 10

Since, the base of the triangle can not be negative number then, x≠ -6feet but x=10feet

Lastly,

Height(h)=X - 4

=10 - 4

=6 feet

However if you are asking how many different combinations, there can be 5005 different combinations.

Answer:

2 different groups of 6 children.

Step-by-step explanation:

There are 15 children you need to bring. You can fit 6 children in each van.

One van : 6 children

Two vans : 12 children

Three vans : 18 children

If you take two vans, that will take 12 children. But you need to fit 15.

If you take three vans, that will take 18 children. This is more than enough.

15 children - 6 = 9 children

Thats one group with 9 children left to take

9 children - 6 = 3 children

Thats two groups with 3 children left to take

3 children - 6 = -3.

This doesn't work. In this case, there will be 3 more empty seats in the last group.

Since the question asks how many groups of 6 children you can drive. It would be two. Becuase there are 2 groups of 6 and one of 3.

Hope it helps.

Do comment if you have any query.

Answer:

y = m x + b       is the standard form for a straight line

you have

y = 6 x + b       if m = 6

Now when x = 2, y = -8          this is given

- 8 = 6 * 2 + b       substituting given values

b = -8 - 12 = -20

y = 6 x -20            is the equation requested

Check;

-8 = 6 * 2 - 20      

12 = 12         so this agrees

y<3/2x-5/2

Step-by-step explanation:

You just have to know how to get y on one side and the rest of the problem on the other.

First you would subtract 3x from both sides, which leaves you with -2y>5-3x.

Lastly you would divide both sides by -2.

Answer:

(2, -4)

Step-by-step explanation:

Answer:

(2, -4)

Step-by-step explanation:

The solution to a system of equations is always going to be the point(s) where they intersect. To solve, use substitution and find each variable, x and y. Our final answer will be a set of coordinates (x, y). To plot this system, see the help image attached.

y = -x - 2

2x - y = 8

Substitute y to find x

2x - (-x - 2) = 8

2x + x + 2 = 8

3x = 6

x = 2

Substitute x to find y

y = -(2) - 2

y = -2 - 2

y = -4

Solution: (2, -4)

There would be 413 frozen dinners in the next 16 years.

Let y represent the amount of frozen dinners after x years.

If a certain quantity of money can buy 940 frozen dinners this year, and it decreases by 5% every year, hence:

y = 940(0.95)ˣ

In 16 years:

y = 940(0.95)¹⁶

y = 413.71

There would be 413 frozen dinners in the next 16 years.
