Answer:

52 1/2 miles

Step-by-step explanation:

Hope this helps!

The number of miles she goes per hour is 52.5 miles.

It is the quantity of an amount of something at a rate of one of another quantity.

In 2 hours, a man can walk for 6 miles

In 1 hour, a man will walk for 3 miles.

We have,

105 miles = 2 hours

Divide both sides with 2.

105/2 miles = 1 hour

1 hour = 52.5 miles

Thus,

52.5 miles per hour.

Answer:

The distributive property tells us how to solve expressions in the form of a(b + c). The distributive property is sometimes called the distributive law of multiplication and division. ... Then we need to remember to multiply first, before doing the addition!

Step-by-step explanation:

Answer:

1.)450.00

2.)336.00

3.)50.40

4.)27.30

Step-by-step explanation:

Answer:

There might be more than one way to approach this one. Here is my way:

In a word problem, always write down the information you have, clearly identifying what any variables represent. If you don't, it could lead to confusion later.

Let's let b represent the speed of the bus. Don't use a different variable for the speed of the car. Since we know it is 10 km/hr faster, let   b+10   represent the speed of the car.

Let t represent the time it takes the bus to travel 200 km.  Since the car takes 1 hour less, use  t-1  to represent the time it takes the car.

Our basic formula for this problem is   distance = rate x time

For the bus,  b·t = 200 km

For the car,  (b+10)·(t-1) = 200 km    Be sure you're clear on these equations. Again, each equation is that vehicles speed times the amount of time it takes. Each vehicle goes 200 km.

If you're sure you understand the two equations, we an go on.

Since both expressions are equal to 200, they are equal to each other, so we can write

    bt = (b+10)(t-1)         Now multiply on the right side, to remove the parentheses. You probably learned the FOIL method in class.

    bt = bt + 10t - 1b - 10        Again, be sure you understand this step before going on. You should do the multiplication yourself to make sure you can do it.

There is a   bt   on both sides of the equation, so subtract  bt  from both sides, to simplify things.

    0 = 10t - b - 10   (I've written b instead of 1b, since 1b is the same as b)

Now we have an equation with two variables in it, so we can't solve it yet. If we go back, we see that bt = 200. If we divide both sides of this by  b , we get   t = 200/b. We can put this expression in place of  t  in our equation.

    0 = 10(200/b) - b - 10

    0 = 2000/b - b - 10

The fraction makes the equation very difficult to work with, so let's multiply both sides of the equation by b, remembering that we have to multiply every term in the equation by b.

    b·0 = b(2000/b) - b·b - b·10

    0 = 2000 - b2 -10b

Let's multiply both sides of the equation by -1 and rearrange the terms. This gives us

    0 = b2 + 10b - 2000   which we can solve by factoring.  You should be able to take it from here. Be sure to answer both questions.

Answer:

4/15

Step-by-step explanation:

there is a total of 15 balls and there is 4 yellow balls

The  probability of picking a yellow ball

Probability is the likelihood or chance that an event will occur.

Probability = Expected outcome/Total outcome

If the bad contains 4 yellow balls 5 red balls and 6 blue balls, the total outcome will be 15 balls

if a yellow ball is selected, the expected outcome will be 4

Pr(selecting a yellow ball) = 4/15

Hence the  probability of picking a yellow ball is 4/15

Answer:

Ww=84 lb

Step-by-step explanation:

Proportions

A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:

y=k.x

Where k is the constant of proportionality.

The value of k is obtained by using the values of a specific point.

The weight of water Ww in a person's body varies directly as their body weight Wb as follows:

Ww=k.Wb

We are given a 170-lb person contains 119 lb of water. Substituting:

119=k.170

Solving for k:

k=119/170=0.7

The function is:

[tex]Ww=0.7\cdot Wb[/tex]

To find how much water is in the body of a 120-lb person, we substitute Wb=120:

[tex]Ww=0.7\cdot 120[/tex]

Ww=84 lb

Step-by-step explanation:

Answer:

[tex]P(X = 0) = 0.1296 [/tex]

Step-by-step explanation:

This can be solved using the binomial distribution because the cars arriving at the stop are independent of each other. This means we will use:

[tex]P(X = x) = \binom{n}{x} p^{x} q^{n - x}[/tex]

Where p is the probability of success, q = 1 - p is the probability of failure and n is the number of cars sampled.

p = 0.4

q = 0.6

n = 4

Therefore,

[tex]P(X = 0) = \binom{4}{0} 0.4^{0} 0.6^{4}[/tex]

This is equal to

[tex]P(X = 0) = 1 \times 1 \times 0.1296 [/tex]

[tex]P(X = 0) = 0.1296 [/tex]

Given:

The volume of water in a tank is modeled by the function

[tex]y=1.15x^3-0.1x^2+2[/tex]

where, x is the number of minutes after the faucet filling the tank is turned on.

To find:

The y-intercept and what does it represent in this context?

Solution:

We have,

[tex]y=1.15x^3-0.1x^2+2[/tex]

Substituting x=0, we get

[tex]y=1.15(0)^3-0.1(0)^2+2[/tex]

[tex]y=0-0+2[/tex]

[tex]y=2[/tex]

Therefore, the y-intercept is 2 and it represents the volume of water in a tank before the faucet filling the tank is turned on.

Answer:

The volume of water in a tank before the faucet filling the tank is turned on.
