Answer:

  28

Step-by-step explanation:

Let x represent the even number between them. Then the desired sum is 2x.

The given relation is ...

  7(x -1) = 1 +6(x +1)

  x = 14 . . . . . . . add 7-6x

 2x = 28 = sum of those numbers

__

The two numbers are 13 and 15.

Answer:

y = 3x + 1.

Step-by-step explanation:

The slope is 3 and the y-intercept is at y = 1.

Answer:

y = 3x + b

Step-by-step explanation:

Essentially the question is asking us to find the equation of the line in slope intercept form

Slope intercept form: y = mx + b

Where m = slope and y = y intercept

First let's find the slope

Slope = change in y over change in x

Looking at the line as y goes up 3 x goes up 1

hence slope (m) = 3/1 or just 3

Now let's find the y intercept

The y intercept is equal to the y value of the point where the line passes the y axis

The line passes the y axis at ( 0 , 1 ) and the y value of that point is 1

Hence, y intercept (.b ) = 1

Finally we substitute 3 for m and 1.for b in y = mx + b to get the equation of the line

We get y = 3x + 1.

Answer:

We are dividing a slab of wood into equal pieces, so the obvious function would be to divide. And how long are the pieces going to be? 1/4 of a foot. so that gives us:

6 ÷ ¼.

Now, when we divide by a fraction, we flip the numerator and denominator and multiply, so the equation will look like:

6 * 4

Solve that, and you'll have your answer.

Step-by-step explanation:

Hope this answer helps you :)

Have a great day

24) IN A PARALLELOGRAM OPPOSITE ANGLES ARE EQUAL

3y + 2 = 62

3y = 62 - 2

3y = 60

y = 60/3

y = 20°

ALSO IN A PARALLELOGRAM ADJACENT SIDES SUM IS 180°

62 + 5x + 3 = 180°

5x + 65 = 180

5x = 180 - 65

5x = 115

x = 115/5

x = 23°

so option c is correct

.

.

.

25) IN A PARALLELOGRAM THE SIDES OF SAME DIAGONAL ARE EQUAL

5x - 4 = 10x - 24

5x - 10x = -24 + 4

-5x = -20

x = 20/5

x = 4

4x + 14 = 3y + 9

4(4) + 14 = 3y + 9

16 + 14 = 3y + 9

30 = 3y + 9

3y = 30 - 9

3y = 21

y = 21/3

y = 7

.

so option b is correct

Answer:

Complementary angles sum to 90°.

∠X has ∠P complementary to it as:

Answer:

6. The word ‘COMMITTEE’ has 9 letters.

So it can be permuted in 9 ways, but we’ve got letters repeating there. To avoid the same arrangements happening again, we eliminate the repetitions.

M repeats twice. T Twice. E twice.

7. If it must be greater than  2000 , the first digit must either be  2  or  3 , which means you will have  2  choices. After that, there will be  3  choices for the second digit. Then there will be  2  choices for the third digit. Lastly there will be just  1  choice for the last digit.

The number of permutations becomes  2×3×2×1=12 .

Step-by-step explanation:

Answer:

The word has 9 letters with 2 Ms, 2Ts and 2Es

We need 2 Ts together, this reduces the number of positions by one.

The number of ways:

Digits 0, 1, 2, 3

Number should be greater than 2000, it means the number is:

or

Total permutations:

Rhombus

Why you failing Geometry its so easy?

Answer:

The tip would be $11.2

Step-by-step explanation:

To find the price of the tip we have to find 16% of the $70 dinner bill.

Therefore we have the following: 0.16 times $70= $11.2

Answer:

  C.  6x² +20x +30

Step-by-step explanation:

The perimeter of a rectangle is given by the formula ...

  P = 2(L +W)

Substituting the given length and width, you have ...

  P = 2((3x² +7x +9) +(3x +6))

Simplifying gives ...

  P = 2(3x² +10x +15)

  P = 6x² +20x +30

"Standard form" has the terms in order of decreasing exponents. The expression of choice D is equivalent, but is not in standard form.

Answer:

x = 6.8829

Step-by-step explanation:

[tex]\frac{sin\left(35\right)}{x}=\frac{sin\left(90\right)}{12}[/tex]

Answer:

x ≈ 6.8

Step-by-step explanation:

Label each side of the triangle with "a" (adjacent), "o" (opposite), or "h" (hypotenuse).

Side x is the opposite, side 12 is the hypotenuse, and the other side is the adjacent.

Use SOH-CAH-TOA to find the missing side (Sin, Cos, Tan).

To find x, we need to use SOH or Sin(a)= O/H

Plug in the adjacent angle for a and 12 for h then solve:

Sin(35)=O/12

The calculator approximation of Sin(35) is 0.5735.

0.5735  ≈ O/12

Multiply both sides by 12:

12 * 0.5735  ≈ O/12 * 12

O ≈ 6.882

Round to nearest tenth:

O ≈ 6.8

Answer:

7

Step-by-step explanation:

a=2

b=2

c=1

2ab cos C=a²+b²-c²=2²+2²-1²=4+4-1=7

Answer:

C

Step-by-step explanation:

Given

a² + b² - 2abcosC = c² ( subtract c² from both sides )

a² + b² - c² - 2abcosC = 0 ( add 2abcosC to both sides )

a² + b² - c² = 2abcosC

Here a = 2, b = 2, c = 1 , then

2² + 2² - 1² = 2abcosC

4 + 4 - 1 = 2abcosC , then

2abcosC = 7 → C

Answer:

Los radios de los círculos son [tex]r_{1} \approx 9.995[/tex], [tex]r_{2} \approx 2.013[/tex], [tex]r_{3} \approx 7.592[/tex], respectivamente.

Las áreas de los círculos son [tex]A_{1} \approx 313.845[/tex], [tex]A_{2} \approx 12.730[/tex], [tex]A_{3} \approx 181.077[/tex], respectivamente.

Step-by-step explanation:

La circunferencia ([tex]s[/tex]) se calcula mediante la siguiente fórmula:

[tex]s = 2\pi\cdot r[/tex] (1)

Donde [tex]r[/tex] es el radio del círculo.

Una vez hallado el radio, se determina el área de la figura geométrica ([tex]A[/tex]) mediante la siguiente fórmula:

[tex]A = \pi\cdot r^{2}[/tex] (2)

Si conocemos que las circunferencias son [tex]s_{1} = 62.8[/tex], [tex]s_{2} = 12.65[/tex] y [tex]s_{3} = 47.7[/tex], respectivamente:

1) Radios de los círculos

[tex]r_{1} = \frac{s_{1}}{2\pi}[/tex], [tex]r_{2} = \frac{s_{2}}{2\pi}[/tex], [tex]r_{3} = \frac{s_{3}}{2\pi}[/tex]

[tex]r_{1} \approx 9.995[/tex], [tex]r_{2} \approx 2.013[/tex], [tex]r_{3} \approx 7.592[/tex]

2) Áreas de los círculos

[tex]A_{1} = \pi\cdot r_{1}^{2}[/tex], [tex]A_{2} = \pi\cdot r_{2}^{2}[/tex], [tex]A_{3} = \pi\cdot r_{3}^{2}[/tex]

[tex]A_{1} \approx 313.845[/tex], [tex]A_{2} \approx 12.730[/tex], [tex]A_{3} \approx 181.077[/tex]

Let's first take a look at our x here. --- (x + 2)^2

Because we are adding a two to our x, this means that we are shifting our graph 2 to the left. Remember that with functions, it's always the opposite!

There is nothing attached to the y, so we are not moving our function up or down.

And then the radius of our circle. Remember that the equation requires us to square this value (... = r^2), so we need to take the square root of 4. The square root of 4 is 2.

With this information, let's now look at our options.

Option A - INCORRECT, the radius is too large

Option B - INCORRECT, this was shifted 2 units to the right

Option C - INCORRECT, the radius is too large

Option D - CORRECT, the radius is 2 and the circle was shifted 2 units to the left

Hope this helps!! :)

Answer:

D

Step-by-step explanation:

The equation for a circle is

(x-h)^2 + (y-k)^2 = r^2

where (h,k) is the center and r is the radius

(x+2)^2 + (y)^2 = 4

Rewritng

(x- -2)^2 + (y-0)^2 = 2^2

The center is at ( -2,0) and the radius is 2

C and D are the only circles with a center at (-2,0)

B,D are the only circles with radius 2

Answer:

[tex]slope = \frac{4}{1} = 1 \\ y - intercept = 3 \\ \therefore \: \: y = 4x + 3[/tex]

Answer:

Step-by-step explanation:

Area of the quarter circle = 1/4 pi * r^2

Area of the quarter circle = 1/4 * 3.14 * r^2

Area of the triangle = 1/2 r * r = 1/2 r^2

Equation of Solution

1/4 3.14 * r^2 = 14 cm^2 + 1/2 * r^2                    Subtract 1/2 r^2 from both sides

0.785 r^2 - 0.5 r^2 = 14 cm^2                           Combine the left

0.285 r^2  = 14. cm^2                                        Divide by 0.285

r^2 = 14/0.285

r^2 = 49.1228                                                     Take the square root of both sides

sqrt(r^2) = sqrt(49.1228)

r = 7.01

Answer:

The formula is 4cm times 9cm which is 36cm. Then times that by pi which is 113.04. The answer is 113.04

Step-by-step explanation:

Answer:

Volume - 452.16 cm

Step-by-step explanation:

First we need to find the area of the circle.

Area of a circle - (3.14)r^2

Insert the radius in the formula -

(3.14) (4)^2

3.14 x 16

50.24 is the area of the circle

Now, we have to multiply this value by the height of the cylinder in order to find the volume.

50.24 x 9 = 452.16 cm

Answer and Step-by-step explanation:

I think this is the correct answer (in picture):

This is because you can either get Heads or Tails, so once you flip it once, you just flip it again and you will get either heads or tails.
