Hugh has $200 in his bank account. Hugh wrote six checks from his account in the following amounts: $20, $20, $12, $20, $12, and $42. He also made a deposit of $57 and was charged a $15 service fee by the bank. After all these transactions what was Hugh's balance?

Answers

The balance in Hugh's account after writing six checks, making one deposit and being charge with a service fee by the bank equals an amount of $ 116.

How to determine the balance of a bank account

Here in this question we should understand the situation like a game with the following rules for the account balance:

A check from the account means a subtraction of money.A deposit means an addition of money.Service fee means also a subtraction of money.

After a careful reading, we apply the rules described above and have the following calculation:

x = $ 200 - $ 20 - $ 20 - $ 12 - $ 20 - $ 12 - $ 42 + $ 57 - $ 15

x = $ 116

Write f(x)=|x-2| as a piecewise function.

Answers

Answer:

Hi! A piecewise function is a function defined by multiple sub-functions, or pieces of different functions over different intervals. Piecewise definition is a way of expressing the function and is not actually integral to the function itself.

f(x) = |x - 2| is an absolute value function. As a piecewise function, it's written like this:

f(x) = {x - 2, x ≥ 2

        {-x + 2, x < 2

Hope this helps! Have a great day.

What is the area of the shaded region below?

Answers

Answer:

Step-by-step explanation:

Remark

The triangle with the shaded region makes exactly 1/4 of the entire circle. So the plan is to find the area of the circle and divide by 4. That gives you the area of the triangle and the shaded region. Then you find the area of the triangle and subtract it from what you just found.

Area of the circle

Area of the circle = pi * r^2

r = 12 cm

pi = 3.14

Area of the circle = 3.14 * 12^2

Area of the circle = 3.14 * 144

Area of the circle = 452.16 cm^2

Area of 1/4 of the circle

Area of 1/4 of the circle = (1/4)*452.16

Area of 1/4 of the circle = 113.04

Area of the triangle

b = r

h = r

b = 12 cm

h = 12 cm

Area = 1/2 b * h

area = 1/2 * 12 * 12

area = 72

Area of the shaded part

Shaded part = area of 1/4 of the circle - area of triangle

Area shaded part = 113.04 - 72 = 41.04

Answer area of shaded part = 41.04

If you spin the spinner 36 times, what is the best prediction possible for the number of times it will not land on yellow?

Answers

The best prediction for the number of times it will not land on yellow would be 29 times.

We have,

Assuming the spinner has an equal probability of landing on each color, The probability of it not landing on yellow is 4/5.

So,

If you spin the spinner 36 times, the expected number of times it will not land on yellow is:

= (4/5) x 36

= 28.8

Since you can't have a fraction of a spin,

= 28

Thus,

The best prediction for the number of times it will not land on yellow would be 29 times.

A. 1°F

Answers

Answer:

C.

Step-by-step explanation:

Since you are subtracting a positive from a negative, your absolute value will get greater. With negative numbers, the less they become in value, the higher their absolute value will get. So, since we are subtracting a positive from a negative, we add them together. However, we need to add them as if they were both positive signs.

Once you do this:

 19

+18

You should get 37. Since -19 has a greater absolute value than 18, you keep the negative sign and apply it to 37, getting you -37.

This is for my Iready and I’m super confused the story problem reads ""Lola rode her bike for 7/10 of an hour on Saturday and 3/5 of an hour on Sunday. How much longer did she ride her bike on Saturday than Sunday?

Answers

First find the decimal values of both fractions:
7/10 is 7 divided by 10 so:
= 0.70

3/5 is 3 divided by 5 so:
= 0.60

60 minutes is one hour (since the question said that Lola rides the bike for 7/10 and 3/5 of an hour)

Now we use these to find how many minutes:
To find 0.70 (or 7/10) of 60 minutes, you multiply 60 x 0.70
= 42 minutes on Saturday

To find 0.60 (or 3/5) of 60 minutes, you multiply 60 x 0.60
= 36 minutes on Sunday

Now to find how much longer she rode her bike on Saturday than Sunday, you subtract the two numbers:
42 - 36
= 6
Therefore, Lola rode her bike for 6 minutes more on Saturday than on Sunday.

The population of a bacteria colony doubles every 6 hours. For example, starting with a sample of 10 bacteria, after 6 hours there would be 20 bacteria and so on.

If the bacteria grow for six hours, each bacterium will divide 3 times per hour × 6 hours = 18 times.

Volume of cylinder is the amount of quantity, which is obtained by the solid or object in the 3 dimensional space.

Here, (d) is the diameter of the base of the cylinder and (h) is the height of the cylinder.

A water sample shows 0.073 grams of some trace element for every cubic centimeter of water. The proportion of element with water is,

[tex]p=\dfrac{0.073}{1}[/tex]

Anthony uses a container in the shape of a right cylinder with a diameter of 11.4 cm and a height of 16.5 cm to collect a second sample, filling the container all the way.

The total volume of the container is,

[tex]V=\dfrac{\pi (11.4)^2\times16.5}{4}\\V\approx1684 \rm\; cm^3[/tex]

The sample contains the same proportion of the trace element. Let the trace element has Anthony collected is x. Thus,

[tex]\dfrac{x}{1684-x}=\dfrac{0.073}{1}\\x=122.932-0.073x\\x+0.073x=122.932\\x=\dfrac{122.932}{1.073}\\x\approx114.6\rm\; gram[/tex]
