Mark had 3 times as many quarters as nickels. He had $1.60 in all. How many nickels and how many quarters did Mark have? x represents . 3x represents .

Answers

Answer 1

Answer:

x represents nickels = 2

3x represents number of quarters = 6

Step-by-step explanation:

x represents nickels

3x represents number of quarters

We'll multiply each of those times the value of the coin they represent, and make that equal to the total amount of money Mark has to get the value of x

x(0.05) + 3x(0.25) = 1.60

0.05x + 0.75x = 1.60

0.80x = 1.60

x = 2 = number of nickels

So 3x = 6 = number of quarters

Checking the math:

2(0.05) + 6(0.25)= 0.10 + 1.50 = 1.60

What is Difference between Pyramid and Prism?

A three-dimensional shape is a pyramid. A pyramid's flat triangular faces unite at a common point known as the apex and have a polygonal base.

A prism is a polyhedron in geometry made up of an n-sided polygon basis, a second base that is a rigidly translated copy of the first base, and n additional faces that must all be parallelograms and connect the corresponding sides of the two bases.

Pyramids and prisms are both three-dimensional solids with flat faces and bases.

Yet, a pyramid only has one base, whereas a prism has two bases that are identical.

Here, the base is rectangular then the figure shows A rectangular pyramid.

A model rocket is launched with an initial upward velocity of 62/ms. The rocket's height h (in meters) after t seconds is given by the following.
h=62t-5t^2
Find all values of t for which the rocket's height is 29 meters.
Round your answer(s) to the nearest hundredth.

Answers

9514 1404 393

Answer:

  t = 0.49, 11.91

Step-by-step explanation:

A graphing calculator can show you the answers quickly. The times are 0.49 seconds and 11.91 seconds.

__

We can write the equation as ...

  h = 29

  62t -5t^2 = 29 . . . . . substitute for h

  -5(t^2 -12.4t) = 29

  -5(t^2 -12.4t +6.2^2) = 29 -5(6.2^2) . . . . complete the square

  -5(t -6.2)^2 = -163.2 . . . . . simplify

  t -6.2 = ±√(-163.2/-5) = ±√32.64 . . . . divide by -5, take the square root

  t = 6.2 ±5.71

  t = 0.49, 11.91

The rocket has a height of 29 meters at t=0.49 seconds and t=11.91 seconds.

Answer:

Step-by-step explanation:

Okay, so this is impossible to tell the amount of spaces, but let's say it was 4000 for VIP and 4000 for Popular Stands. Multiply $30 by 4000, and you get $120k Earnings. To check your answer, Divide 120,000 by 4000, and you get $30 for each stand.

Now, let's move on with the VIP stands. A VIP Stand costs $50, so 4,000 x $50 = $200k earnings. To check your answer, divide 200,000 by 4000, and you get $50 for each VIP Stand.

If you need to find each variant, go by 1k seat increments, i.e. 1000 and 7000, 2000 and 6000, etc.

A fair number cube and a spinner are used in a game. The faces of the number
cube are labeled 1 through 6. The spinner has an equal chance of landing on 1 of 5
colors: red, green, blue, yellow or black. What is the probability of a player rolling an
even number and then spinning green?

Answers

Answer:

1 /10

Step-by-step explanation:

Fair cube ; numbered (1 - 6)

Spinner ; (red, green, blue, yellow or black)

Even numbers = (2, 4, 6)

Probability of obtaining an even number on rollin g a fair cube :

Probability = required outcome / Total possible outcomes

P(even number) = 3 /6 = 1/2

P(green color on spinner) = 1 /5

P(even number and green color) = 1/2 * 1/5 = 1/10

What is the gross earnings for a person who has $26,480 in total sales,
$1250 in Returns and Allowances, and a rate of commission of 7%?

Answers

Answer:

$3103.6

Step-by-step explanation:

Given data

Total sales= $26,480

Returns and Allowances=$1250

Commission = 7%

Let us find the amount in commission earned

=7/100*26,480

=0.07*26480

=$1853.6

Hence the gross earnings

=1853.6+1250

=$3103.6

A circular hot spring has a diameter of 106 meters. Over time, the diameter of the spring decreases by 2 meters. By how many square meters does the area of the hot spring decrease? Use 3.14 for

Answers

Answer:

The area decreased by 329.7 square meters.

Step-by-step explanation:

For a circle of diameter D, the area is:

A = pi*(D/2)^2

with pi = 3.14

In this case, we start with a circle of D = 106m

Then the initial area is:

A = 3.14*(106m/2)^2 = 8,820.26 m^2

After, the diameter is decreased by two meters, then the new diameter is:

D' = 106m - 2m = 104m

And the new area will be:

A' = 3.14*(104m/2)^2 = 8,490.56 m^2

The change in the area is A - A' = 8,820.26 m^2 - 8,490.56 m^2 = 329.7m^2

The area decreased by 329.7 square meters.
