34 equals c minus 19

Answers

Answer 1

Answer:
$34 = c - 19$
add 19 to both sides:
$34 + 19 = c$
$53 = c$

You have a can that is in the shape of a cylinder. It has a volume of about 1,738 cubic centimeters. The height of the can use 23 centimeters. What is the approximate length of the radius? Use 3.14 for pi

Answers

Answer:

~8.7

Step-by-step explanation:

So we know that the formula for volume is 3.14 * r^2 * h.

So first we do 1738/23 to get an ugly ~ 75.6 Now he have to square root that to get r.

The square root of 75.6 is ~ 8.7

Arezo borrowed $2,500 from her grandfather. This graph shows the balance remaining on Arezo’s debt after she makes each payment. Using this graph, how much will she owe after 4 payments?

Answers

Answer:

She will owe $500 after 4 payments.

Step-by-step explanation:

With the help of graph

Number of payments (x) Balance remaining(y)

0 2500

1 2000

2 1500

Since it is linear function .

So, we will use two point slope form to find the equation for the given situation.

$y-y_1=(y_2-y_1)/(x_2-x_1)(x-x_1)$ ----A

$(x_1,y_1)=(0,2500)$

$(x_2,y_2)=(1,2000)$

Substitute the values in A

$y-2500=(2000-2500)/(1-0)(x-0)$

$y-2500=-500x$

$y=-500x+2500$

Where x is the number of payments

y is the remaining payment

This equation represents the given situation.

So, to find the amount remaining after 4 payments .Substitute x =4

$y=-500(4)+2500$

$y=-2000+2500$

$y=500$

Hence she will owe $500 after 4 payments.

Answer:

She will owe $500

To take a taxi, it costs \$3.00 plus an additional \$2.00per mile traveled. You spent exactly \$20 on a taxi, which includes the \$1 tip you left. How many miles did you travel

Answers

A taxi ride where the total fare is $3, $2 for every mile travelled plus a $1 tip and the original cost of $20.

First write a formula that expresses the cost of the ride:

Total cost= Flat fee + Mileage + Tip

Now let's drop in what we know:

20= 3+2 (miles) +1 - we know the total cost is 20, the fee of 3, the tip of 1 and the cost per mile of 2. The only thing we don't know is the number of miles. So let's solve for that.

Subtract 3 and 1 from both sides to get:

16=2(miles)

Divide both sides by 2:

8=miles
Therefore, you traveled 8 miles.

Lines are in the form y=mx+b, where m is the slope and b is the y-intercept. This line is thus y=9/4x-14, so C is correct. Multiplying by four, we get 4y=9x-56. Adding 56 and subtracting 4y, we see that 9x-4y=56, and multiplying by -1, we get 4y-9x=-56, so A is also correct. At this point, it is clear that B and D are incorrect, so A and C only are correct.

You know that you can spot the slope and intercept right away
IF you 'solve' the equation for 'y'. Then you'll have

y = (slope) x + (intercept) .

So for choices 'A' and 'B', you have to massage the equation
into the standard form, and then just look at it and see whether
the slope is 9/4 and the intercept is -14.

A).         -9x + 4y =   -56

Add 9x to each side:    4y = 9x - 56

Divide each side by 4 :   y = 9/4 x - 14    <== Yes ! Good one.

B). 9x + 4y = 56

Subtract 9x from each side:   4y = -9x   + 56

Divide each side by 4 :       y = -9/4 + 14 <= no, signs are wrong

C). Yes. Slope is 9/4 and intercept is -14 .

D). No. Slope is 9/4 alright, but intercept is +14, not -14 .

There are 20 million bacteria per square centimeter of coral in a coral reef. The coral reef covers 13000 km^2. How many bacteria are there in the coral reef?

Answers

Answer:

2.6 * $10^(21)$ bacteria

Step-by-step explanation:

We know that there are 20 million bacteria in 1 $cm^2$ of coral reef. Let's write the number of bacteria in scientific notation with powers of 10:

$20,000,000= 2*10^7$

Now let's write 1 $cm^2$ in square meters, knowing that one cm equal 0.01 meter ( $10^(-2)$ meters:

$1 \, cm^2 = 1* (10^(-2)\,m)^2= 10^(-4)\, m^2$

So now we can find how many bacteria there is in one $m^2$ of coral reef:

Number of bacteria in $1\,m^2 = 2 * 10^7* 10^4 = 2 * 10^(11)$ bacteria

we can now express 13000 $km^2$ in $m^2$ knowing that 1 km = 1000 m = $10^3$ m:

$13000\,km^2= 1.3 * 10^4 \,km^2=1.3 * 10^4*(10^3m)^2= 1.3*10^4*10^6\'m^2=$

Since we know the number of bacteria per every $m^2$ of coral reef, the number of bacteria in $1.3*10^(10)\,m^2$ of coral reef will be the product of these two numbers:
