What is the measure of angle TRV?
O 20°
O 50°
60°
O 130°

Answer:

The number that is a perfect square remains on the outside and the one that isn't, stays on the inside. For example, you can make the number 2[tex]\sqrt{3}[/tex] only when the number on the outside is a perfect square. The original number was 4, so it reduced down to 2, and the other number stayed in the radical

Answer:

Step-by-step explanation:

They are dividing the denominator by 3. So, the answer is 2/1 or basically the number 2.

For example,

27/3 = 9

9/3 = 3

The last math shows how I got the answer.

Hope this helps!

Answer:

2

Step-by-step explanation:

The sequence is multiplying by 3 each time.  2/27 *3= 2/9

2/9 *3 is 2/3.

2/3*3= 2

2 is the next term

Answer:

Use the distance formula to calculate the length of all three sides, and check whether all sides are congruent.

Step-by-step explanation:

An equilateral triangle would have three sides that are all the same length, out of these options, only using the distance formula to calculate the length of all three sides and checking whether they are all congruent will make sure that the triangle is equilateral instead of just isosceles.

Answer:

y = 4x + 16 (fourth answer choice)

Step-by-step explanation:

From the given equation we can immediately discern that the slope of these lines is 4 (as they are parallel).

Starting with the slope-intercept formula y = mx + b, we get:

32 = 4(4) + b, or 16 = b, or y = 4x + 16

Answer:

1, 3, 9, 27, 81, is a geometric sequence.

Step-by-step explanation:

A geometric sequence is basically a sequence of numbers that's multiplied by or divided one specific set number each time.

0, 2, 6, 12, 72, does not have a set number it is multiplied or divided by each time.

4, 9, 14, 19, 24, adds 5 each time, it doesn't multiply

Answer: B. y = -3x

Step-by-step explanation:

By plugging in the given point into each answer choice for the x and y values for which ever equation is true that is the correct answer.

For the purpose of speeding things up the correct answer is B y = -3x

If we plug in the point give, (1, -3) for (x, y) then we get the equation:

-3 = -3 * 1

This equation when solved: -3 = -3 which is true so this is the correct answer.

Answer:

d=3

Step-by-step explanation:

by using distance formula

d=√(x2-x1)²+(y2-y1)²

let the points be A(-3,2) B(0,2)

d=√(0--3)²+(2-2)²

d=√(+3)²+(0)²

d=√9

d=3

Step-by-step explanation:

Answer:

9 × (1 × 4) = (9 × 1) × 4

Step-by-step explanation:

Number 3 because the associative property states that it doesn't matter how you add / multiply something in sets.

9 × (1 × 4) = (9 × 1) × 4 shows 9 × 1 × 4 in 2 ways with 2 sets.

Answer:

9 × (1 × 4) = (9 × 1) × 4 is the answer because it means you can group in any combination

Step-by-step explanation:

9 × (1 × 4) = (9 × 1) × 4

Answer:

see explanation

Step-by-step explanation:

(a)

Given

x² + 10x + 16

Consider the factors of the constant term (+ 16) which sum to give the coefficient of the x- term (+ 10)

The factors are + 2 and + 8, since

2 × 8 = 16 and 2 + 8 = 10, thus

x² + 10x + 16 = (x + 2)x + 8)

---------------------------------------------------

(b)

Given

x² + 7x + 12

Consider the factors of the constant term (+ 12) which sum to give the coefficient of the x- term (+ 7)

The factors are + 3 and + 4, since

3 × 4 = 12 and 3 + 4 = 7, thus

x² + 7x + 12 = (x + 3)(x + 4)

------------------------------------------------------

(c)

Given

x² + 13x + 12

Consider the factors of the constant term (+ 12) which sum to give the coefficient of the x- term (+ 13)

The factors are + 1 and + 12, since

1 × 12 = 12 and 1 + 12 = 13, thus

x² + 13x + 12 = (x + 1)(x + 12)

Answer:

300 Adults 555 Children

Step-by-step explanation:

What we know:

Firstly, at 5pm there were 36 more Children (C) than Adults (A)

So.....C = A + 36

Secondly, at 12pm there were 5 x more Children and 4 x more Adults and the total was 855

So 4A + 5C = 855

——-

Now use ‘C = A + 36’ and get rid of all ‘C’ in the second equation.....

4A + 5C = 855

becomes......

4A + 5 (A + 36) = 855

Multiply the brackets (5 x A) and (5 x 36):

4A + 5A + 180 = 855

Take off 180 from both sides:

4A + 5A = 675

Therefore 9A = 675

Divide by 9:

A = 75

We know C is A + 36

C = 111

At 5 pm - A = 75 and C = 111

Therefore at 12:

There were 5 x C = 555

And 4 x A = 300

Answer:

[tex]kx-2=0[/tex]

Step-by-step explanation:

We are given that  an equation

[tex]3kx+2kx=10[/tex]

We have to find the  value of x by rearrange the equation

Subtract 10 on both sides then we get

[tex]3kx+2kx-10=0[/tex]

Now, combine like terms

[tex]5kx-10=0[/tex]

Now, taking common factor

[tex]5(kx-2)=0[/tex]

[tex]5\neq 0[/tex]

Therefore,

[tex]kx-2=0[/tex]

This is required equation to solve for x.
