How can I put this into an equation?

Not sure for number 2, but for number 3:

n=4.5

Step-by-step explanation:

let eqn be y = mx + b.

2x + 9y = 8

9y = -2x + 8

y = -2/9 x + 8/9

since the lines are perpendicular, product of the slope of the two lines = -1.

hence,

m x -2/9 = -1

m = 9/2

sub (0, -3):

-3 = 9/2(0) + b

b = -3

therefore equation is: y = 9/2x - 3

Answer:

y = 6

Step-by-step explanation:

The red square represents a 90 degree angle. If you subtract 36 from 90 you will get 54. Then to find y, divide 54 by 9 and you get 6.

Step-by-step explanation:

Answer: 56% of people in the audience are male.

Step-by-step explanation:

Given : Total people in the audience = 143

Number of females = 63

Number males = (Total people ) - (Number of females )

= 143 -63

= 80

The percent of people in the audience are male = [tex]\dfrac{\text{Number of males}}{\text{Total people}}\times100\%[/tex]

[tex]\dfrac{80}{143}\times100\%=55.94\%\approx56\%[/tex]

Hence, 56% of people in the audience are male.

The laws of exponents I will be using are:

[tex](x^y)^z = x^{yz}[/tex], and [tex]x^y \cdot x^z = x^{y+z}[/tex].

For the first part, [tex](15^3)^3 \cdot 15^{-6} = 15^9 \cdot 15^{-6} = 15^3[/tex].

For the second part, [tex]15 \cdot (15^3)^2 \cdot (15^{-5})^2 = 15 \cdot (15^6) \cdot (15^{-10}) = 15^{1+6-10} = 15^{-3} = \frac{1}{15^3}[/tex].

Answer:

x = -1

Step-by-step explanation:

Start out by making the equations equal to each other since we are trying to find x (if x is the same for both equations, which it is for this problem due to the equations shown above).

18x + 26 = 2x + 10

Now that the equation is set up to find x, we need to get x by itself. Now subtract 2x on all sides to get all the x variables on the same side. Apply the same logic for the normal numbers by subtracting 26 on all sides to get the normal numbers on one side. You should end up with the numbers shown below for this step:

18x + 26 = 2x + 10

-2x   -26   -2x  -26

16x = -16

For the final step, remember that we want x by itself, so we have to divide both sides by 16 to get x by itself. After dividing both sides, you should end up with x = -1.

16x = -16

16      16

x = -1

240:180

Step-by-step explanation:

Answer:

x = 35, x = 27

Step-by-step explanation:

(9)

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

141° is an exterior angle, thus

x + 24 + 2x + 12 = 141 , that is

3x + 36 = 141 ( subtract 36 from both sides )

3x = 105 ( divide both sides by 3 )

x = 35

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

(11)

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

2x - 9 + 3x + 2x = 180

7x - 9 = 180 ( add 9 to both sides )

7x = 189 ( divide both sides by 7 )

x = 27

Answer:

Unfortunately I can't do the first one, but the second one is easy

Step-by-step explanation:

To find X in the Q) 11:

1. The triangle is an equilateral traingles meaning angles add up to 180°

2. Add the numbers - 2x - 9 + 3x + 2x = 7x -9

3. Add 9 to 180 (your adding because you changed the side of the number) - 189 = 7x

4. Divide 7 by 189

Your answer is x = 27

Answer:

x = 17

Step-by-step explanation:

[tex]45 + 68 + (3x+16) = 180 \\ \\ 113 + 3x + 16 = 180 \\ \\ 129 + 3x = 180 \\ \\ 3x = 180 - 129 \\ \\ 3x = 51 \\ \\ x = \frac{51}{3} \\ \\ x = 17[/tex]

Answer:

Distance = 4 miles

Displacement = 0

Step-by-step explanation:

Given that :

Speed of honey bee = 4mph

Total travel time = 1 hour

Distance traveled by the honey bee:

Distance traveled = speed * time

Distance traveled = 4mph * 1 hour

Distance traveled = 4 miles

Displacement = 0 miles ; change in distance from initial position.

Since initial position of the honeybee is the beehive and its final position is the beehive. Hence, the change from its initial position is zero

Answer:

6583.5 cm³

Step-by-step explanation:

[tex]\boxed{volume \: of \: hemisphere = \frac{2}{3}\pi {r}^{3} }[/tex]

[tex]\boxed{volume \: of \: cylinder = \pi {r}^{2} h}[/tex]

Thus, volume of half cylinder= ½πr²h

Since both has a radius of 10.5cm, substitute r= 10.5 into both formulas. The value of h is 24 since it is given that the height of the half cylinder is 24cm.

Volume of composite solid

[tex] = \frac{2}{3}( \frac{22}{7})(10.5^{3} ) + \frac{1}{2} ( \frac{22}{7} )( {10.5}^{2} )(24) \\ = 2425.5 + 4158 \\ = 6583.5 \: cm^{3} [/tex]

Answer:

C: Glenda has been over charged by $3.40 for her purchase

Step-by-step explanation:

The amount Glenda is to pay can be found by applying arithmetic

operations to the given parameters in the correct order.

Reasons:

The price of each picture frame = $12.95

Number of picture frame purchased = 4

Price of each mat = $5.89

Number of mats purchased = 4

Total purchase price = $12.95 × 4 + $5.89 × 4 = $75.36

Total purchase price + Tax = $75.36 × 0.065 + $75.36 ≈ $80.26

Express Shipping charges for amount of purchase between $50 to $100 is given from the table as; $8.20

Total bill = Total purchase + Tax + Shipping

Therefore;

Total bill = $80.26 + $8.20 = $88.46

Amount the credit card is billed = $91.86

Amount of over charge = $91.86 - $88.46 = $3.40

Therefore, Glenda has been over charged by $3.40 for her purchase
