Dustin has only nickels and quarters in his piggy bank. He was 49 total for combined value of $8.85. How many of each type of co

Troyanec [42]

Let's use the variables N and Q for the number of nickels and the number of quarters.

We know there are 49 total coins, so we can write the following equation:

N + Q = 49

We can solve this equation for one variable which will help in the next step. Let's solve for N:

N = 49 - Q

Next, we know that nickels are worth $0.05 and quarters are worth $0.25. We can use these values along with the total value of $8.85 to create another equation.

0.05N + 0.25Q = 8.85

Now we can use substitution to solve our system out equations. We solved the first equation for N, so we can plug 49 - Q in for N.

0.05(49-Q) + 0.25Q = 8.85

Distribute and combine like terms.

2.45 - 0.05Q + 0.25Q = 8.85

2.45 + 0.2Q = 8.85

0.2Q = 6.4

Q = 32

Plug 32 in for Q in N + Q = 49 to find the number of nickels.

N + 32 = 49

N = 17

Dustin has 32 quarters and 17 nickels.

What is 5.72 × 10^3 in standard form?

iVinArrow [24]

Answer: 5,720

Step-by-step explanation: The number shown here 5.72 × 10³ is written in scientific notation since it's composed of a decimal between 1 and 10 in this case 5.72 and a power of 10 in this case 10³. To write 5.72 × 10³ in standard notation, we first begin with 5.72.

Next, we look at the exponent which in this case is positive 3. The exponent tells us to move the decimal point three places to the right.

Finally, we fill in the missing positions with zeros.

Therefore, 5.72 × 10³ written in standard notation is 5,720.

jarptica [38.1K]

First square each term to rid of the root sign:
x^2 + 1^2 + 3^2 = 0^2
x^2 + 1 + 9 = 0
x^2 = -10
x = root -10

Jenna has a round trampoline with an area of 153.86 feet squared. Jenna is 2 points

astraxan [27]

Answer:

The length of the cover that will wrap around the edge of the trampoline is 43.96 ft.

Step-by-step explanation:

Given that,

Area of trampoline, $A=153.86\ ft^2$

Jeena wants to buy a cover to put around the edge of the trampoline. We need to find the length of the cover that will wrap around the edge of the trampoline. First of all, lets find the radius of trampoline. Let is is r. So,

$\pi r^2=153.86 \\\\r=\sqrt{\dfrac{153.86 }{3.14}} \\\\r=7\ ft$

To find the length of the cover that will wrap around the edge of the trampoline we will find circumference of the trampoline as :

$C=2\pi r\\\\C=2\times 3.14\times 7\\\\C=43.96\ ft$

So, the length of the cover that will wrap around the edge of the trampoline is 43.96 ft.
