c) both balls taken will be the same colour

Answer:

D

Step-by-step explanation:

in order to get the process of solving the equation, we need to solve it.

our goal to solve the equation 6x-19=77 is to isolate the variable onto one side, and have the numbers (value of x) on the other

we have the equation:

6x-19=77

first, we can get rid of -19 on the left side and leave 6x on that side by adding 19 to both sides (-19+19=0).

The reason why we're adding 19 to both sides is because if we do something to one side, we have to do it to the other side to make sure the value of the equation stays the same.

6x-19= 77

   +19  +19

_________

6x=96

now, we do have the variables on one side and the numbers on another side, but we aren't done yet, as we want the value of x by itself

divide by 6 on both sides

x=16 (because 6x/6=1x, or x. 96/6=16).

the option of D shows the same method I did and has the correct answer as well.

This is what was given for D:

6x-19=77

6x-19+19=77+19

6x=96

6x/6=96/6

x=16

(same thing I did)

So D is the correct answer.

Hope this helps!

Answer:

Y = 16a + 12b

Step-by-step explanation:

Given:

Cost of each neckless = $16

Cost of each bracelet = $12

Find:

Equation for the following state

Computation:

Assume;

Number of neckless sale in a month = a

Number of bracelet sale in a month = b

Total amount she earn = Y

So,

Total amount she earn = (Cost of each neckless)(Number of neckless sale in a month) + (Cost of each bracelet)(Number of bracelet sale in a month)

Y = (16)(a) + (12)(b)

Y = 16a + 12b

The total distance that Jacob and his dad hiked from their campsite to the top of the mountain is approximately 7,105.92 feet.

To calculate the total distance Jacob and his dad hiked from their campsite to the top of the mountain, we need to consider the width of the base of the mountain and the height of the mountain.

Given:

Base width of the mountain: 2,600 feet

Since the mountain is pretty much isosceles, we can assume that the height of the mountain is equal to the length of the two equal sides of the triangle formed.

To find the height of the mountain, we can use the Pythagorean theorem.

Let's assume the height of the mountain is 'h' feet.

Using the Pythagorean theorem, we have:

[tex](2,600/2)^2 + h^2 = 2,600^2[/tex]

Simplifying the equation:

[tex]1,300^2 + h^2 = 2,600^2\\1,690,000 + h^2 = 6,760,000[/tex]

[tex]h^2 = 6,760,000 - 1,690,000\\h^2 = 5,070,000[/tex]

Taking the square root of both sides:

h = sqrt(5,070,000)

h ≈ 2,252.96 feet

Now we can calculate the total distance they hiked from their campsite to the top of the mountain by considering the base width and the height of the mountain.

Total distance = Base width + 2 × Height

Total distance = 2,600 + 2 × 2,252.96

Total distance ≈ 2,600 + 4,505.92

Total distance ≈ 7,105.92 feet

Therefore, the total distance that Jacob and his dad hiked from their campsite to the top of the mountain is approximately 7,105.92 feet.

Answer:

37 ft

Step-by-step explanation:

The ladder forms a right triangle as it elan's against the wall of the boat house.

Thus, the length of the ladder can be determined using Pythagorean theorem.

c² = a² + b²

c = length of ladder

a = 35 ft

b = 12 ft

Plug in the values

c² = 35² + 12²

c² = 1,225 + 144

c² = 1,369

c = √1,369

c = 37

Therefore, to reach the roof of the boathouse, the length of the ladder = 37 ft

Step-by-step explanation:

Ah...right triangle trig. Gotta love this stuff (you better, because it never goes away!). We need to remember SohCahToa which tells us that the sin of an angle is equal to the side opposite the angle over the hypotenuse; the cos of an angle is equal to the side adjacent to the angle over the hypotenuse; the tan of an angle is equal to the side opposite the angle over the side adjacent the angle. x is the side across from our given angle, while 7 is the side adjacent. That means that we will use the tangent ratio to solve.

[tex]tan\theta=\frac{opp}{adj}[/tex] and filling in:

[tex]tan48=\frac{x}{7}[/tex]. Solving for x:

7tan(48) = x. Do this on your calculator in DEGREE mode (NOT radians!) to get that x = 7.77 which rounds nicely to D: 7.8

Probability of picking out a basketball card = 2/5

Probability of picking out a football card = 1/3

Therefore, the probability of picking out a soccer card will be:

= (1 - 2/5 - 1/3)

= (15/15 - 6/15 - 5/15)

= 4/15

Therefore, the probability that Justice will randomly pick out a soccer card is 4/15.
