B.

Answer:80.25

Step-by-step explanation:

Answer:

There are 16 nickels and 15 dimes.

Step-by-step explanation:

let x = number of dimes

let y = number of nickels

x + y = 31

.1x + .05y = 2.30

Solve x + y = 31 for x

x = 31 - y

multiple the second equation by 100 to eliminate the decimals.

10x + 5y = 230  Substitute 31 - y for x

10(31-y) + 5y = 230  Distribute the 10

310 -10y + 5y = 230  Combine like terms

310 -5y = 230  Subtract 310 from both sides

-5y = -80  Divide both sides by -5

y = 16

There are 16 nickels.

Plug in 16 for y to solve for x

x + y = 31

x + 16 = 31  Subtract 16 from both sides

x = 15

There are 15 times.

Check:

10x + 5y = 230

10(15) + 5(16) = 230

150 + 80 = 230

230 = 230

Answer:

The distributive law of multiplication states that when a number is multiplied with the sum is equal to the number multiplied by each addend with the number and then sum of the both products.

by example a*(b+c)=(a*b) + (a*c)

Here the expression A is (5/6)*250

the expression B is ( 1/3 × 250 ) + ( 1/2 × 250 )

expression B is ( 1/3 × 250 ) + ( 1/2 × 250 )

=250*(1/3+1/2) applying distributive law of the multiplication

=250*((2+3)/6)

=250*(5/6)

=(5/6)*250

Therefore the expression A is equal to the expression B.

Answer: its (6,5)

Step-by-step explanation:

Answer:

(6,9)

You move the pin once to the left and three to the top, and at the end, it will reach (6,9) since there is no more grid to move it to.

Answer:

yes

Step-by-step explanation:

if we put 3 1/4 to decimal for we get 3.25

Trail B is shorter than that

Trail A is already 3.1

Trail B is obviously between those two

so 3.15

Answer: There are between 9 and 10 ounces of fluid in container B.

Step-by-step explanation: There are between 9 and 10 ounces of fluid in container B. To find the number of ounces in container B, divide the number of ounces in container A by 8. This gives 76 / 8 = <<76/8=9.5>>9.5 ounces. Since 9.5 is between 9 and 10, the correct answer is "There are between 9 and 10 ounces of fluid in container B."

To find the scale of the model train boxcar, we need to determine the ratio of the actual size of the boxcar to the size of the model. We can do this by dividing the actual size of the boxcar by the size of the model:

scale = actual size / model size

Plugging in the values from the problem, we get:

scale = 606 inches / 6 inches

Simplifying this expression gives us:

scale = 101

So, the scale of the model train boxcar is 101. This means that for every 1 inch of the model, there are 101 inches in the actual size.

Answer: -22.25

Step-by-step explanation:

I think this is how to do it but the way you explained the expression was slightly confusing but I set it up like this:

(3/10)^2 - 17 + (-7/ | 4.3 - 7.8 |) x 2.67

then when I simplified the expression I received an answer of -22.23 which is close to one of the given answers of -22.25

Hopefully this was correct, sorry that I couldn't be of more help

sorry misread the question

-7/9 x 3/5

[tex] \frac{ - 7}{9} \times \frac{3}{5} \: \\ (3 \: and \: 9 \: are \: common \: so \: we \: can \: simplify them) \\ \frac{ - 7}{3} \times \frac{1}{5} \\ \frac{ - 7 \times 1}{3 \times 5} = \frac{ - 7}{15} [/tex]

Answer:

Option A.

Step-by-step explanation:

When x = - 5, y = - 1,

lhs of (1) = - 10 + 5 = - 5

lhs of (2) = - 1 + 2 = 1

When x = 0, y = 1,

lhs of (1) = 0 - 5 = - 5

lhs of (2) = 1 - 0 = 1

Answer: Y is 9 when X is 12.

Step-by-step explanation:

Here is how you do it.

1. Make a table of x and y

x: 4,

y:3,

2. Keep continuing the table with list of numbers until x=12

x:4,8,12

y=3,6,9.

As you can see, when x is 12 y is 9.

To find the distance between the points (6.6,7.9) and (6.6,4.7), we can use the distance formula:

distance = √((x2 - x1)^2 + (y2 - y1)^2)

Plugging in the coordinates of the two points, we get:

distance = √((6.6 - 6.6)^2 + (4.7 - 7.9)^2)

Simplifying this expression gives us:

distance = √((0)^2 + (-3.2)^2)

Which simplifies to:

distance = √(10.24)

Finally, taking the square root of both sides gives us:

distance = 3.2

So, the distance between the points (6.6,7.9) and (6.6,4.7) is approximately 3.2.

Answer:

Step-by-step explanation:

1. 13 x 8 - One pair of wings needs one yard of fabric, which is $8. Therefore, one pair of wings cost $8.

2. 104 - The result of multiplying 13 x 8

3. 13 x (4 x 2) - This is easier because smaller numbers are more familiar and understandable to our brains.

4. 13 x (4 x 2)

13 x 4 = 52

52 x 2 = 104

Step-by-step explanation:

It would take 43 years for the plant specie to become invasive.

We know that the increase of the plant is following the exponential function and this can be seen from the question that we have here. We now have to create a model that we can use to solve the question.

Using

Pt = Poe^rt

Pt = population at time t

Po = initial population

r = population growth rate

t = time taken

Then;

10000 =500e^0.07t

10000/500 = e^0.07t

20 = e^0.07t

ln20 = 0.07t

t = ln20/0.07

t = 43 years
