what is the answer to x= ??

Answer: 90 visitors per hour

Explanation: "Per hour" means in 1 hour, so we can rewrite the given statement using fractions as 450 visitors/5 hours = __visitors/1 hour.

To find out what goes in the bank, notice that we

have a 1 in the denominator of our second fraction.

So we want to find a fraction that is equivalent

to 450/5 that has a 1 in the denominator.

If we divide the numerator and denominator of 450/5 by 5,

we get the equivalent fraction 90/1 or 90 visitors/1 hour.

So now we have 90 visitors/1 hour = __visitors/1 hour.

So a 90 must go in the blank.

This means that the museum sees 90 visitors per hour.

Answer:

It is more likely that Danny will make three free throw shots in a row.

Step-by-step explanation:

The probabilities of Craig and Danny making the throw they attempt, is given as:

Probability that Craig will make the throw = 55% = 0.55

Probability that Danny will make the throw = 71% = 0.71

Now, the probabilities that they will miss the throw can be found out by subtracting the probabilities, that they can make the throw, from 1.

Probability that Craig will miss the throw = 1 - 0.55 = 0.45

Probability that Danny will miss the throw = 1 - 0.71 = 029

Now,

Probability that Craig will miss two throws in a row = (0.45)(0.45)  Probability that Craig will miss two throws in a row = 0.2025

And,

Probability that Danny will make three throws in a row = (0.71)(0.71)(0.71)

Probability that Danny will make three throws in a row = 0.3579

Since, the probability of Danny making three throws in a row is higher than the probability of Craig missing two throws in a row.

Thus, it is clear that, it is more likely that Danny will make three free throw shots in a row.

Answer:

x = 24

Step-by-step explanation:

T = 24.93 + 0.21x      Substitute 30.18 for T

30.18 = 24.94 + 0.21x

-24.94  - 24.94              Subtract 24.94 from both sides

5.24 = 0.21x                   Divide both sides by 0.21

x = 24.95 ≈ 24 because you can't have a partial text message.

Step-by-step explanation:

if y=5-x then ...

a would be y=5-1 = 4

b would be y=5-2 =3

c would be y=5-4 =1

d would be y=5-3 =2

Answer:

Correct option: Third one -> 8.2 units

Step-by-step explanation:

Assuming that the function that models the amount of radioactive material remaining after x hours is:

f(x)=10*(0.98)^x

To find the amount of material after 10 hours, we just need to use x = 10 in the equation and find the value of f(x):

f(10) = 10*(0.98)^10

f(10) = 8.1707

Rounding to nearest tenth, we have f(10) = 8.2

Correct option: Third one

Answer:

correct answer is C 8.2 units

Answer: F(x, y) = 40x + 25y

Step-by-step explanation:

Given the following :

x = number of leather wallets

y = number of canvas wallets

PROFIT on canvas wallet = $25

PROFIT on leather wallet = $40

Function that calculates the total profit on both wallets:

Profit on each wallet type is the product of the profit per wallet and the number of wallet.

The total profit generated on each wallet type is given by :

F(x) = 40x - - - - (1) leather wallet

F(y) = 25y - - - - (2) canvas wallet

Adding (1) and (2) to get total profit on both wallets:

F(x, y) = 40x + 25y

Answer:

C

Step-by-step explanation:

2 x pi x r = circumfrence

2 x 7 x pi = 43.96

Answer: 43.96 m

Step-by-step explanation: To find the circumference of the circle shown here, start with the formula for the circumference of a circle which is shown below.

Circumference = 2πr

Notice that the radius of the circle is 7 meters.

So we can plug in 7 meters for r in the formula.

So we have (2)(π)(7m) which is equal to 14π m.

So the circumference of the circle shown here is 14π m.

Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the circumference by plugging in 3.14 for π.

So we have (14)(3.14) which is equal to 43.96.

So the circumference of the circle is

approximately equal to 43.96 m.

Answer:

Perimeter: [tex]p = 4\cdot l[/tex], Total costs: [tex]C = 24\cdot l[/tex]

Step-by-step explanation:

The garden has a square form. Let be [tex]l[/tex] the length of any of the sides, measured in yards. The perimeter of the garden, measured in yards, is:

[tex]p = 4\cdot l[/tex]

Now, perimeter has a length unit and total costs of edging the garden, measured in US dollar, is:

[tex]C = \left(6\,\frac{USD}{yard} \right)\cdot 4\cdot l[/tex]

[tex]C = 24\cdot l[/tex]

Answer:

volume

Step-by-step explanation:

You can use a graphing calculator to have a function y = x^(1/3) and see what the y values are for the particular x values shown. Alternatively you can compute each input to get (-8)^(1/3) = -2, and (-1)^(1/3) = -1 and so on. The exponent of 1/3 is another way of writing cube root.

The cube root is the opposite of cubing something. If we go from 2 to 2^3 = 8, then reversing this has us go from 8 to 2. Think of a block of clay that is 2 by 2 by 2. The volume of this block is 8 cubic units. If you want to find the side length, then you would apply the cube root (or do guess and check).

Answer: 1. multiplication

Step-by-step explanation:

Suppose that you want to change an object with length L with a scale factor a, then the lenght of the rescaled object will be:

L' = a*L

Then the correct option is 1) multiplication.

Notice that sometimes you may find that the scale factor is a number like 1/5 and when you find the new lenght you will end with something like:

L' = L/5 that seems like a division, but this is actually the multiplication between L and 1/5.

Answer:

1/4 = 25%

Step-by-step explanation:

The probability of heads is 1/2.

The probability of an even number on a die is 3/6 = 1/2.

The probability of both is (1/2) (1/2) = 1/4, or 25%.

Answer:

make me brainlist pls pls pls pls

Step-by-step explanation:

A "fair" coin lands heads-up half of the time and "tails-up" half of the time.

For one flip, the probability of landing heads-up is 1/2.

Of those successes, we now consider the probability of the "fair" die landing with an even number on top. This probability is (number of successes) / (total number of possibilities) = 3/6, or 1/2.

So, the probability of both events happening ("and") is 1/2 of 1/2, or (1/2)*(1/2) = 1/4.

Answer:

x = - 3, x = - 2

Step-by-step explanation:

Given

x² + 5x + 6 = 0

Consider the factors of the constant term (+ 6) which sum to give the coefficient of the x- term (+ 5)

The factors are + 3 and + 2, since

3 × 2 = + 6 and 3 + 2 = + 5, thus

(x + 3)(x + 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x + 2 = 0 ⇒ x = - 2

Answer:

x= -2 or -3

Step-by-step explanation:

First, you find the two factors that can replace +5 to enable you to factorize. To do this, you find the factors of +6 and check the factors that when added would give +5.

The factors are +2 and +3

x²+ 5x+6=0

x²+2x+3x+6=0

x(x+2)+3(x+2)=0

(x+2)(x+3)=0

x+2=0                 or                 x+3=0

x= -2                   or                 x= -3

∴x= -2 or -3

Answer: 45 handshakes.

Step-by-step explanation:

We have 10 kids.

Let's count.

Kid 1, can meet other 9 kids, so here we have 9 handshakes.

Kid 2, he can meet other 9 kids, but he already handshaked kid 1, so here we only count 8 handshakes.

Kid 3, he can meet other 9 kids, but we already counted the handshake with kid 1 and kid 2, so from here we only count 7 handshakes.

You can see the pattern, the total number of handshakes will be:

H = 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1  = 45

Answer:

The total period should be 14 months and not 141414 months.

Thus answer will be: number of months spent in Brazil is 5 months and he spent 9 months in Portugal.

Step-by-step explanation:

Let the number of months he lived in Portugal be X and the number of months he lived in Brazil be Y: Thus we have:

X  +  Y  = 14 months.

He learned an average of 130 new words per month when he lived in Portugal: 130 x number of months (X) = 130X

and an average of 150 new words per month when he lived in Brazil: 150 x number of months in Brazil (Y) = 150Y.

Thus we have 130X + 150Y  = 1920

Since X  +  Y = 14: make X subject of formula: X = 14 - Y. then substitute this for X in the equation below

130X + 150Y  = 1920

130(14-Y) + 150Y = 1920

1820 - 130Y + 150Y = 1920

150Y - 130Y = 1920 - 1820

 20Y = 100

    Y = 100/ 20 = 5 months

Thus number of months spent in Brazil is 5 months. To find the number of months spent in portugal, use the first equation:

    X  +  Y = 14 where Y is 5

   X = 14 - 5 = 9 months. Thus he spent 9 months in Portugal
