Answer:

I think its either B, or C

Step-by-step explanation:

because in a equation your looking for the y intercept and the y intercept is usually the number without x by it.

The equation associated with the total cost is y = 60x + 80 and the y-intercept of it will be $80 thus option (A) is correct.

A straight line on the coordinate plane is represented by a linear function.

The formula for a linear function is f(x) = ax + b, where a and b are real values.

In another word, a linear function is a function that varies linearly with respect to the changing variable.

As per the given,

They found a rental company that charges a fixed fee of $80 plus an additional fee of $60 per hour.

Total cost = 80 × number of hours + fixed cost

y = 86x + 80

y-intercept , x = 0

y = 60(0) + 80

y = 80

Hence"The equation associated with the total cost is y = 60x + 80 and the y-intercept of it will be $80".

Answer:110

Step-by-step explanation:

The value of the given expression is 10.

The square root of a number is the inverse operation of squaring a number. The square of a number is the value that is obtained when we multiply the number by itself, while the square root of a number is obtained by finding a number that when squared gives the original number.

Given that, expression is √10×√10.

= (√10)²

= 10

Therefore, the value of the given expression is 10.

Answer:

126°

Step-by-step explanation:

(2x +18)° = (3x)°

2x + 18 = 3x

18 = 3x - 2x

18 = x

therefore, (3x)° = (3*18)°= (54)°

[tex]m\angle SRW + (3x)\degree = 180\degree \\

m\angle SRW + 54\degree  = 180\degree \\

m\angle SRW = 180\degree  - 54\degree  \\

Answer:

Step-by-step explanation:

The radius of the base of the cone is 4.27 cm.

The vertical angle of a cone is also known as the apex angle. The apex angle of a cone is the angle at the top of the cone, where the slant height and the two radii meet.

The formula for calculating the radius of a cone is:

tan(apex angle) = height / radius

In this case, the apex angle is 54°, the height is 6 cm, and we need to find the radius.

tan(54°) = 6 cm / radius

radius = 6 cm / tan(54°)

radius = 4.27 cm

Therefore, the radius of the base of the cone is 4.27 cm.

Answer:

Option 1

Step-by-step explanation:

Counter-intuitively, the correct answer is option 1. Option 2 is obviously a cross section, since it is the shape of the base of the triangle. Option 3 is also obviously a cross section, since the figure is a triangular prism. Option 4 is a cross section because, if you slice diagonally, you may create a cross section with a wider base on the bottom and larger on top. However, it is impossible to create a cross section of a rectangle from this square pyramid. Hope this helps!

Answer:

it is a 26:4 probability if you simplify it it would be 6.5:1

Step-by-step explanation:

The probability of randomly choosing a green candy, replacing that candy and  choosing another green candy is 1/75 and this can be determined by using the given data.

Given :

A bag of Skittles candy contains 8 red, 12 blue, 4 green, and 6 orange.

The following steps can be used in order to determine the probability of randomly choosing a green candy, replacing that candy and  choosing another green candy:

Step 1 - First, determine the total number of candies in the bag.

[tex]\rm Total\; Candy = 8 + 12 + 4 +6[/tex]

[tex]\rm Total\; Candy = 30[/tex]

Step 2 - The total number of green candies in the bag is 4.

Step 3 - So, the probability of randomly choosing a green candy, replacing that candy and  choosing another green candy is:

[tex]P = \dfrac{4}{30}\times \dfrac{3}{30}[/tex]

Step 4 - Simplify the above expression.

[tex]P = \dfrac{12}{900}[/tex]

[tex]p=\dfrac{1}{75}[/tex]

The probability of randomly choosing a green candy, replacing that candy and  choosing another green candy is 1/75.

Answer: C. 35

Step-by-step explanation:

x + 73 + 51 + 21 = 180

180-73-51- 21 = x

x = 35

Answer:

X= 35

Step-by-step explanation:

In order to find X, you need to add all the known angles together

- 73+ 51+ 21+ 145

Because the total degrees of an angle is 180 degrees, you need to subtract the known degrees from the total

- 180- 145= 35  

x = 35

Hope this helped

formula:

(a+b)^2

= a^2+2ab+b^2

Here, we have x^2  (as in a^2)

and -6x (as in 2ab), which, we're missing the b^2

(I'm not really sure how to describe this but bare with me)

-6/2 (-6 is from the -6x) = -3 (the b)

-3^2 = -3*-3 which is equal to 9 (positive 9)

Writing it out -

x^2-6x+9 = -5

- Addition of inequality -

Since we add 9 to the left side, we have to add 9 to the right side; which gives us:

x^2-6x+9=4

Next, lets put the x^2-6x+9 as in (a+b)^2:

(x-3)^2 = 4

Then let's do the square root of equality (square rooting both sides) :

x-3 = 2

Finally lets add 3 to both sides

x = 5

THE ANSWER IS x=5

Answer:

336

Step-by-step explanation:

The total number of ways to order your favorite 3 desserts from a menu of 8 is 336, the correct option is D.

We can use combinations for this case,

Total number of distinguishable things is m.

Out of those m things, k things are to be chosen such that their order doesn't matter.

This can be done in total of

[tex]D ^mC_k = \dfrac{m!}{k! \times (m-k)!} ways.[/tex]

If the order matters, then each of those choice of k distinct items would be permuted k! times.

So, total number of choices in that case would be:

[tex]^mP_k = k! \times ^mC_k = k! \times \dfrac{m!}{k! \times (m-k)!} = \dfrac{m!}{ (m-k)!}\\\\^mP_k = \dfrac{m!}{ (m-k)!}[/tex]

This is called permutation of k items chosen out of m items (all distinct).

We are given that;

The number of ways to order 3 desserts from a menu of 8 is given by the combination formula:

C(8,3) = 8! / (3! * (8-3)!) = 56

This means there are 56 different ways to choose 3 desserts from the menu of 8. Once the desserts are chosen, there are 3! = 6 ways to order them.

For 3 desserts from a menu of 8

56 * 6 = 336

Therefore, by  combinations and permutations answer will be 336.
