Answer:

x = 10

Step-by-step explanation:

Both right triangles are similar.

-> Corresponding sides of similar triangles are in proportion.

[tex] \implies \: \frac{x + 6}{16} = \frac{x}{10} \\ \\ \implies \: 10(x + 6) = 16x \\ \\ \implies \: 10x + 60= 16x \\ \\ \implies \: 10x - 16x = - 60 \\ \\ \implies \: - 6x = - 60 \\ \\ \implies \: x = \frac{ - 60}{ - 6} \\ \\ \implies \: x = 10[/tex]

Answer:

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.

To get the final answer of y<3/2x-5/2

y=6x-20

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

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.

Answer:

9/70

Step-by-step explanation:

Given that:

70 students choose to attend one of three after school activities: football, tennis or running.

There are 30 boys. 13 students choose football, of which 9 are girls. 31 students choose tennis. 9 girls choose running.

A student is selected at random.

What is the probability this student chose running?

Since it asking for the probability of this student (randomly select) chose running. And we can see that there are 9 girls choose running.

Therefore, we also know 70 students is the total

Hence, the answer is 9/70

9/70 is in simplest form already.

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:

(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)

$0.7

Given sentence:

Writing as an equation:

[tex]\implies 2.4 \ \text{pounds} = \$1.68[/tex]

To obtain the cost per pound of peas, divide 2.4 both sides. This will convert the value on the L.H.S to 1 pound. The value obtained on the R.H.S will be the the cost (answer).

[tex]\implies \dfrac{2.4 \ \text{pounds}}{2.4} = \$\dfrac{1.68}{2.4}[/tex]

[tex]\implies 1 \ \text{pounds}}= \$\dfrac{1.68}{2.4}[/tex]

[tex]\implies 1 \ \text{pound} = \$0.7[/tex]

Typically, linear equations are written in slope-intercept form:

[tex]y=mx+b[/tex]

To find the equation of a line given a point and the slope:

We're given:

[tex]y=mx+b[/tex]

⇒ Plug in the slope, [tex]\dfrac{1}{5}[/tex]:

[tex]y=\dfrac{1}{5}x+b[/tex]

⇒ Plug in the point (-5,-4) and solve for b:

[tex]-4=\dfrac{1}{5}(-5)+b\\\\-4=-1+b\\\\b=-3[/tex]

⇒ Therefore, the y-intercept of the line is -3. Plug this back into our original equation as b:

[tex]y=\dfrac{1}{5}x-3[/tex]

[tex]y=\dfrac{1}{5}x-3[/tex]

Answer:

5(4v+1)

Use the distributive property to multiply 5 by 4v+1.

20v+5

Answer:

20v+5

Step-by-step explanation:

You would multiply using the distributive property

Distributive property formula examples:

Answer: -x(x-4)(2x-49)

Step-by-step explanation:

Add and subtract the second term to the expression and factor by grouping.

Answer:

-x (x-4) (2x-49)

Step-by-step explanation:

take out -x

you then have

2x^2-57x+196

then factor the remaining

multiply number next to x^2 which is a with 196 which is c

(-57 is b)

multiply 2 with 196 which = 392

then find out what 2 factors of 392 add up to -57

they are -8 and -49

2(x-8/2)(x-49/2)=0

2(x-49/2)(x-8/2)=0

(-x)(2x-49)(x-4)=0

Step-by-step explanation:

Integration of the given function involves straightforward application of the power rule. It can also be done easily by a modern calculator.

  [tex]\displaystyle \int_{1000}^{1300}{(190x-1370)}\,dx=95(1300^2-1000^2)-1370(1300-1000)\\\\=95(300)(2300)-1370(300)=300(95\cdot2300-1370)\\\\=65\,139\,000[/tex]

Revenue from the sale of those 300 tickets will be $65,139,000.

The Ruiz family using a rounded figure for exchange rate will not give the correct exchange.

Exchange rate:

1 euro = 1.35261 USD

1.35261 rounded to the nearest hundredth = 1.35

If Ruiz family is exchanging 50 euros for instance

Original exchange rate

1 euro = 1.35261 USD

50 euro = 67.6305

Rounded exchange rate:

1 euro = 1.35 USD

50 euro = 67.5 USD

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 %

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.
