Answer:

The answer is 14

Step-by-step explanation:

The taxi driver charges $4 per mile so you multiply that by 3 miles because that is what your trying to find. So you get 12 and from their you have to add the $2 fee thus leading to an answer of 14.

Answer:

96m/s

Step-by-step explanation:

Given the velocity, v, in ft/s of an object given by the formula v=v0−32t,

Given

V = 39ft/s

t = 2secs

Required.

Initial velocity v0

Substitute the given parameters into the formula

v=v0−32t,

32 = v0-32(2)

v0 = 32+64

v0 = 96m/s

Hence the initial velocity of the object is 96m/s

Answer: D Equilateral

Step-by-step explanation: Center of a triangle is a point where lines intersect. There 4 most popular: centroid, circumcenter, orthocenter and incenter.

Altitude or Height of a triangle is a perpendicular line is draw from a vertex to the opposite side. There are 3 heights and they united (or intersect) at a point called Orthocenter

Incenter is a point where the three angle bisectors meet. Angle bisector is a line that divide the angles of the triangle in two equal angles.

Generally, each center is positioned at a different location on the triangle (in one example, the point is located outside the triangle).

However, there is a case in which incenter and orthocenter are coincidental. That case is for a equilateral triangle, a triangle whose angles and sides are the same.

Answer:

[tex]x + 5 = 8[/tex]

Step-by-step explanation:

Given

[tex]Total = 8[/tex]

[tex]Additional\ Vacation = 5[/tex]

Required

Determine the equation to find initial days of vacation

This is represented with x.

To get a total of 8 days vacation, we must have the following expression.

[tex]Initial\ Days + Additional\ Days = Total[/tex]

Substitute values for initial days, additional days and total. So, we have

[tex]x + 5 = 8[/tex]

Hence, the required expression is: [tex]x + 5 = 8[/tex]

Answer:

1/4

Step-by-step explanation:

Step-by-step explanation:

Answer:

5/16

Step-by-step explanation:

Use binomial probability:

P = nCr pʳ qⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1−p).

Let's say r is the number of male puppies.

n = 5, r = 2, p = 0.5, and q = 0.5.

P = ₅C₂ (0.5)² (0.5)³

P = 5/16

The probability of getting two males and three females, assuming an even chance for  each gender is [tex]\frac{5}{16}[/tex].

Given that,

Based on the above information, the calculation is as follows:

Here we use binomial probability:

[tex]P = ^nC_r p^r q^{n-r}[/tex]

Here n denotes the number of trials,

r denotes the number of successes,

p denotes the probability of success,

and q denotes the probability of failure (1−p).

Let's us assume the r be the number of male puppies.

Now  

n = 5, r = 2, p = 0.5, and q = 0.5.

So, put the values

So,  

[tex]P = ^5C_2 (0.5)^2 (0.5)^3[/tex]

= [tex]5 \div 16[/tex]

Therefore we can conclude that the probability of getting two males and three females, assuming an even chance for  each gender is [tex]\frac{5}{16}[/tex].

Answer:

Brand A costs approximately $0.21 per ounce

Brand B costs approximately $0.18 per ounce

Step-by-step explanation:

the rate can be regarded as the change in one entity with respect to the other

From the question, we know brand A

$ 2.55 for 12 ounces of juice, to Know the cost of single once of the juice is

($ 2.55/12ounce)

=$ 0.2125

But the conversation rate for dollar to cent is (1 dollar = 100 cents)

Then to convert $ 0.2125 to cent, we can say

1 dollar = 100 cents

$ 0.2125 =X cent , if we cross multiply we have

= 21.25 cents

Which is approximately 21 cents.

From the question, Brand B cost $ 1.45 for 8 ounces of juice.

to Know the cost of single once of the juice is ( $ 1.45/8 ounce)

=$ 0.18125

We can convert to cent like we did above

1 dollar = 100 cents

$ 0.18125 =X cents, if we cross multiply, we have

= 18.125 cents

which is approximately: 18 cents

Therefore, the true statement about the unit rate are"Brand A costs approximately $0.21 per ounce

Brand B costs approximately $0.18 per ounce"

Answer:

Step-by-step explanation:

The equation of line is y = ( 1/4 )x - 1 , where the slope is m = ( 1/4 ) and the graph is plotted

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Let the equation of line be represented as A

Now , the value of A is

y = ( 1/4 )x - 1

Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Substituting the values in the equation , we get

Slope m = 1/4

The y-intercept of the line is b = -1

The graph of the line y = ( 1/4 )x - 1 is plotted

Hence , the equation of line is y = ( 1/4 )x - 1

Answer:

Step-by-step explanation:

The vertex form of the equation of the parabola with vertex (h, k)  is:

f(x) = a(x - h)² + k

so the equation of parabola with the vertex (4, 7) is

f(x) = a(x - 4)² + 7  

passes through the point (0, 10)  means if x=0 then f(x)=10

10 = a(0 - 4)² + 7  

10 -7 = a(-4)² + 7 -7

3 = 16a

a = ³/₁₆

Therefore the equation of parabla is:

                                  f(x) =  ³/₁₆ (x - 4)² + 7

The probability of drawing a white marble on the first draw, followed by a black marble on the second is 4/15.

Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.

The probability of drawing a white marble on the first draw, followed by a black marble on the second  = (number of white marbles / total number of marbles) x (number of black marbles / total number of marbles - 1)
