Answer:

8 red haired and 42 brown haired

Step-by-step explanation:

I chose a random number to start off with (which is 8) and I multiplied it by 5.

8•5=40 and then you have to add 2, so you get 42.

42+8 = 50

The equation would be (5x+2)+x where 'x' is the number of people with red hair.

Answer:

309 full rolls

Step-by-step explanation:

Find how many full rolls he had by dividing 15,483 by 50:

15,483/50

= 309.66

Since the question asks for full rolls, the answer has to be a full number.

So, the answer is 309 full rolls

Answer:It is 5/8 of a pound heavier

Step-by-step explanation:

1 1/4 - 5/8=5/8

Answer:

The larger package is twice as heavy

Step-by-step explanation:

first make 1 1/4 into 5/4 and then multiply the top and the bottom by 2 to get a common denominator of 8. you will end up with 10/8. you can then subtract 5/8 from 10/8, leaving you with 5/8.

Answer:

a. Yes

b. 3x+7

c. 105 cm

Step-by-step explanation:

a. a(1)+b=10

   a(2)+b=13

when you solve this by elimination or simultaneously: a=3 and b=7

∴ f(x)=3x+7

b. f(x)=3x+7

c. 3(35)+7=112 cm

Answer:

= 9

Step-by-step explanation:

There are two angles given.

One is 90 and the other is 45.

90+45=135

180-135=45°

This proves that the triangle is isosceles.

This means that two angles are equal, but also two side lengths are the same.

In this triangle, the equal sides are CB and AC.

Therefore, AC is equal to 9.

Answer:

B. 2/9

Step-by-step explanation:

f(x)=2 • 3^x

f(-2)=2 • 3^(-2)

f(-2)=2 • 1/9

f(-2)=2/9

65^2 = 39^2 + b^2

4225 = 1521 + b^2

b^2 = 4225 - 1521

b^2 = 2704

b = √2704

b = 52 inches

Answer:

0.8 i guess

Step-by-step explanation:

The row including x=0.7 in the table is the closest to the actual solution for the expression [tex]\sqrt{(2x+3)}=\dfrac{x}{(x+5)}+2[/tex].

In order to find the actual solution of any algebraic expression, we can graph it and the point at which the graph intersects the axis is its actual solution.

First, we will find the actual solution of the expression [tex]\sqrt{(2x+3)}=\frac{x}{(x+5)}+2[/tex]  by graphing it.

From the graph, we can see that the expression intersects when x=0.7 so, the actual solution is 0.7.

Thus, the 0.7 row in the table is the closest to the actual solution.

Answer:

B) all real numbers expect 4pi+8pi where n is any integer

Step-by-step explanation:

The domain of the function y = tan(x/8) is given by: All real numbers except 4π+8nπ , where n is any integer.

The domain is the set that contains all possible input values for the function.

Since we know that Tangent of an angle is sine of the angle divided by the cosine of the angle, and the cosine is 0 at:

π/2 + nπ

Hence, let a composite tangent function , the domain is given by:

f(x) does not equal to π/2 + nπ

we have that , hence the domain is:

all real numbers except 4π+8nπ

All real numbers except 4π+8nπ, where n is any integer.

Answer:

The magnitude of the resultant force is: 27.40 pounds

Step-by-step explanation:

Given

[tex]F_1 = 45[/tex]

[tex]F_2 = 50[/tex]

[tex]\theta = 33[/tex]

Required

The magnitude of the resultant vector

To do this, we apply cosine formula

[tex]R^2 = F_1^2 + F_2^2 - 2 * F_1 * F_2 * \cos(\theta)[/tex]

This gives:

[tex]R^2 = 45^2 + 50^2 - 2 * 45 * 50 * \cos(33)[/tex]

[tex]R^2 = 2025+ 2500 - 4500* 0.8387[/tex]

[tex]R^2 = 2025+ 2500 - 3774.15[/tex]

[tex]R^2 = 750.85[/tex]

Take square roots of both sides

[tex]R = \sqrt{750.85\\[/tex]

[tex]R = 27.40[/tex]

Answer:

3V/ (pi r^2) = h

Step-by-step explanation:

V = 1/3 pi r^2 h

Solve for h

Multiply each side by 3

3V = 3 * 1/3 pi r^2 h

3V =  pi r^2 h

Divide each side by pi r^2

3V/ (pi r^2) = pi r^2 h/ ( pi r^2)

3V/ (pi r^2) = h

Answer:

n = - [tex]\frac{4}{7}[/tex]

Step-by-step explanation:

Given

[tex]\frac{2}{3}[/tex] (1 + n) = - [tex]\frac{1}{2}[/tex] n

Multiply both sides by 6 ( the LCM of 3 and 2 ) to clear the fractions

4(1 + n) = - 3n ← distribute left side

4 + 4n = - 3n ( add 3n to both sides )

4 + 7n = 0 ( subtract 4 from both sides )

7n = - 4 ( divide both sides by 7 )

n = - [tex]\frac{4}{7}[/tex]

Answer:

3. x = 11.6

4. f = 2 g = 2

Step-by-step explanation:

3) (3x - 7) + (4x + 6) = 90 --> x = 11.6

4) 3f + 1 = 5f - 15 ---> f = 2

6g - 5 = 3f + 1

6g = 3(2) + 6 ---> g = 2
