Answer:

45°

Step-by-step explanation:

If the lines are parallel then you know that the straight line has a total degree of 180. you know that part of the line is 135 degrees so 180-135=45

Complete question:

Russell has a collection of 1,200 pennies. Of these pennies, 25% are dated before 1980, 35% are dated from 1980 to 2000, and the rest are dated after 2000. How many pennies in Russell’s collection are dated after 2000?

Answer:

480 pennies

Step-by-step explanation:

Total pennies = 1200

Datwd before 1980 = 25%

Dated 1980 - 2000 = 35%

The rest are Dated after 2000 ;

How many are dated after 2000

Dated before 1980 = 25% ;

25% of 1200

0.25 * 1200 = 300

Dated 1980 - 2000 = 35% ;

0.35 * 1200 = 420

Dated after 2000 ;

1200 - (300 + 420)

1200 - 720

= 480 pennies

Step-by-step explanation:

Answer:

2.4 gallons every minute

Step-by-step explanation:

Since we are given three values and one variable that needs to be solved in a ratio problem we can use the Rule of Three to solve for the flow rate of the water with this being represented as x.

4 [tex]\frac{1}{2}[/tex] or 4.5 gallons  <============>  1 [tex]\frac{7}{8}[/tex] or 1.875 minute

     x   gallons   <==============> 1 minute

(1 * 4.5) / 1.875 = x

2.4 gallons = x

Therefore, we can see that the flow rate is 2.4 gallons every minute, meaning that every single minute that the hose is on, it will deposit 2.4 gallons of water into the fish tank.

=======================================================

Explanation:

If the diagonals were congruent, then you can use the SSS property to prove a pair of right triangles are congruent. This leads to showing that we have adjacent congruent corresponding angles. Let's call those angles x and y.

Since they are congruent, we know that y = x. Adjacent angles of any parallelogram add to 180, so x+y = 180

By substitution we can solve for x

x+y = 180

x+x = 180

2x = 180

x = 180/2

x = 90

So y = 90 as well.

This line of thinking is used to show that all four angles of this parallelogram are 90 degrees. A rectangle is any quadrilateral in which all four angles are 90 degrees, so that's why this parallelogram is a rectangle.

Answer:

12 dollars per ticket

Step-by-step explanation:

Answer:

-Martha would add $0.36 each day.

-Martha would have $7 in her coin bank after 6 days.

Step-by-step explanation:

1 quarter= $0.25

1 nickel= $0.05

1 penny= $0.01

To find the amount she adds each day, you have to add the results of multiplying each coin added on a day for its value:

1*0.25+1*0.05+6*0.01=0.25+0.05+0.06=0.36

This means that Martha would add $0.36 each day.

Then, to find the amount of money that was in her coin bank after 6 days, you have to add the amount she put on the coin bank plus the amount she added each day for the number of days:

$4.84+($0.36*6)=$4.84+$2.16=$7

According to this, Martha would have $7 in her coin bank after 6 days.

31 is between the square numbers 25 and 36, whose respective square-roots are 5 and 6.  Lets take the median of 25 and 36 to see how far in the middle 31 is.

(25 + 36) / 2 = 61 / 2 = 30.5

This is close to 31.

Take the median of the square-roots.

(5 + 6) / 2 = 11 / 2 = 5.5   This is the median square-root.

Square-root of 31 is between 5.5 and 6.

√31 = 5.55

r = 0,288m

Stapsgewijze uitleg:

Volume van de strandballen V = 4 / 3πr³

1 liter = 0,001 cm³

100l = x

x = 100 * 0,001

x = 0,1 m³

Vervangen in de formule en verkrijg de straal

0,1 = 4 / 3πr³

0,3 = 4πr³

r³ = 0,3 / 4 (3,14)

r³ = 0,3 / 12,56

r³ = 0,02388

r = ∛0,02388

r = 0,288m

Vandaar dat de straal van de strandballen 0.288m is

What is 3.16161616161616161616 as a fraction?

To write 3.16161616161616161616 as a fraction you have to write 3.16161616161616161616 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.

3.16161616161616161616 = 3.16161616161616161616/1 = 31.616161616162/10 = 316.16161616162/100 = 3161.6161616162/1000 = 31616.161616162/10000 = 316161.61616162/100000 = 3161616.1616162/1000000 = 31616161.616162/10000000 = 316161616.16162/100000000 = 3161616161.6162/1000000000 = 31616161616.162/10000000000 = 316161616161.62/100000000000 = 3161616161616.2/1000000000000 = 31616161616162/10000000000000

And finally we have:

3.16161616161616161616 as a fraction equals 31616161616162/10000000000000

Step-by-step explanation:

3.16161616 ... = 313 99 = 3 16 99  

Explanation: It appears that you mean  3.16161616 ... , let  x = 3.16161616 ... , then  100 x = 316.16161616 ...

Subtracting former from latter we get 99 x = 313 and  x = 313 99 = 3 16 99 Hence  3.16161616 ... = 3 16 99

Given:

Total distance for daily exercise is  [tex]2\dfrac{1}{2}\text{ miles}[/tex].

You run 1/3 of that distance on a hill.

You run down a slope for the last 1/2 of the hill.

To find:

The distance you run down the slope.

Solution:

We have,

Total distance [tex]=2\dfrac{1}{2}\text{ miles}[/tex]

You run 1/3 of that distance on a hill.

Distance on a hill [tex]=\dfrac{1}{3}\times 2\dfrac{1}{2}\text{ miles}[/tex]

You run down a slope for the last 1/2 of the hill.

Distance you run down the slope [tex]=\dfrac{1}{2}\times \dfrac{1}{3}\times 2\dfrac{1}{2}\text{ miles}[/tex]

[tex]=\dfrac{1}{6}\times \dfrac{2\times 2+1}{2}\text{ miles}[/tex]

[tex]=\dfrac{1}{6}\times \dfrac{5}{2}\text{ miles}[/tex]

[tex]=\dfrac{5}{12}\text{ miles}[/tex]

In cannot be expressed as mixed fraction because 5<12.

Therefore, the distance you run down the slope is [tex]\dfrac{5}{12}\text{ miles}[/tex].

The answer for the question provided is 10^4×4^5

Answer:

D. The product of one and any other real number is the number itself.

Step-by-step explanation:

Multiplicative Identity Property can also be referred to as the identity property.

It states that when a number , a real number is multiplied by 1, the result is that same real number itself.

For example:

2 × 1 = 2

-5 × 1 = -5

Therefore, option D. The product of one and any other real number is the number itself. Is the correct option.

Answer:

(6, -9)

Step-by-step explanation:

Eliminate y (you can do x too, but y is easier for this problem)

To eliminate y we must get 0y

If one is 2y, the other must be -2y to get to 0

Keep the first equation the same

7x + 2y = 24

Multiply all numbers in the second equation by -2 (so y can be -2y)

-8x + -2y = -30

Positive + Negative = Negative

-8x - 2y = -30

Now add/subtract the two equations from each other

7x + 2y = 24

-8x - 2y = -30

-1x + 0y = -6

-1x = -6

Divide both sides by -1 to isolate variable

-1x ÷ -1 = -6 ÷ -1

x = 6

We could simply plug in the x value into one of the equations, but that's substitution - not elimination. Repeat the same steps for x

I will multiply the first equation by 4 to get 28x and the second equation by -7 to get -28x for an answer of 0x

28x + 8y = 96

-28x - 7y = -105

0x + 1y = -9

1y = -9

Divide both sides by 1 to isolate the variable

1y ÷ 1 = -9 ÷ 1

y = -9
