Jade’s weekly paycheck is $306.25. She makes $8.75 per hour. Divide to find the number of hours per week Jade works.

Answers

Answer:

35 hours a week

Step-by-step explanation:

306.25 / 8.75

Answer:

Jade works for a total of 35 hours per week.

Step-by-step explanation:

Since Jade's weekly paycheck is $306.35, and she makes $8.75 per hour, we need to divide the weekly amount by the hourly amount to find the amount of weeks that Jade works.

$306.25 ÷ $8.75 = 35

Therefore, Jade works for a total of 35 hours per week.

for what base-6 digit $d$ is $2dd5 6$ divisible by the base 10 number 11? (here $2dd5 6$ represents a base-6 number whose first digit is 2, whose last digit is 5, and whose middle two digits are both equal to $d$).

Answers

The digits base is 7 then we should convert them into base 6.

The exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logbn.

Here the conclusion is that there are many bases in the mathematics so what will happen is that we should convert these bases. For example, we have to convert base 10 of a number which is called decimal number can be converted into binary number whose base is 2 and after then if the digits base is 7 then we should convert them into base 6.

The distance around the outside of cedar parks is 0.8 miles joanie ran 0.25 of the distance during her lunch break how far did she run

Answers

Answer:

If the total distance is 0.8km we need to multiply that amount by the proportion that she ran, which was 0.25 (one quarter or 25%). So 0.8km x 0.25 = 0.2km Looking another way, the word 'of' often means the same as 'multiply', so 0.25 of 0.8km = 0.25 x 0.8km = 0.2km Joanie ran a total of 0.2 km during her lunch break.

find the equation of a circle with a center at (-1, 5) and a point on the circle is (4, 4). ( x 1) 2 ( y - 5) 2

Answers

The equation of a circle is x² + y²+ 2x - 10y = 0 with a center at (-1, 5).

What is the equation of a circle?

The equation of a circle with center (h,k) and radius r is :

r² = (x−h)² + (y−k)²

Given that a circle with a center at (-1, 5) and a point on the circle is (4, 4).

Since the circle passes through points (4, 4),

So the radius (r) of the circle is the distance between points (-1, 5) and (4, 4).

⇒ r² = (-1−4)² + (5−4)² = 25 + 1

⇒ r = √26

The center of the circle is given as (h,k) = (-1, 5)

So the equation of the circle is

⇒ r² = (x − h)² + (y − k)²

Substitute the values of r, h, and k in the above equation,

⇒ 26 = (x − (-1))² + (y −5)²

⇒ 26 = (x + 1)² + (y −5)²

⇒ 26 = x² + 2x +1 + y² - 10y + 25

⇒ x² + y²+ 2x - 10y = 0

Hence, the equation of a circle is x² + y²+ 2x - 10y = 0 with a center at (-1, 5).

tHE SPEED OF SOUND IN AIR IS 1100 FEET PER SECOND. THE SPEED OF SOUND IN STEEL IS 1500 FEET PER SECOND. ROBIN ONE EAR PRESSED AGAINST THE RAILROAD TRACK, HEARS A SOUND THROUGH THE RAIL SIX SECONDS BEFORE HEARING THE SAME SOUND THROUGH THE AIR. TO THE NEAREST FOOT HOW FAR AWAY IS THE SOURCE OF THAT SOUND

Answers

To the nearest foot the distance of source of that sound is 24,750 feet.

Given that;

Speed of sound in air = 1100 feet per second

Speed of sound in steel = 1500 feet per second

Time difference = 6 seconds

We have to find the nearest foot for the distance of source of that sound.

What is relation between distance, speed and time?

The relation between distance, speed and time is;

Speed = Distance/Time

We have;

Time difference = 6 seconds

Let the distance = x feet.

For the air;

Distance = x feet

Speed of sound in air = 1100 feet per second

Then, Time = Distance/speed = x / 1100

And, For steel ;

Distance = x feet

Speed of sound in steel = 1500 feet per second

Hence, Time = Distance/speed = x/1500

Since, Time difference = 6 seconds

Hence, The equation become;

x / 1100 - x/1500 = 6

(1500x - 1100x)/1100*1500 = 6

400x = 6 * 1100 * 1500

x = 24,750 feet.

Hence, To the nearest foot the distance of source of that sound is 24,750 feet.

If a sample has a small standard deviation, we can say the scores in the sample are.

Answers

If a sample has a small standard deviation, we can say the scores in the sample are consistent.

Standard deviation is a measure of dispersion. It measures the variation of the scores from the central value of the distribution.

A data is said to be consistent when this variation is less. Such data are easy to handle for studies.

When it is difficult to study the very large population, we choose samples from the population randomly. Each of these samples also have its own standard deviation. When this standard deviation is small, then the data is more consistent. That is, the scores in the sample goes well with those in the population.

Troy invests $540 in a savings account that earns a simple interest
rate of 2.3% annually. How much money will Troy have in
the account after four years assuming he does not deposit or
withdraw any money?
please help:)

Answers

wish i could help bro bro.

Answer/step-by-step explanation:

Well, we first need to find out what 2.3 of $540 is.

540 x 2.3 = 1,242.

Now, we need to find what the yearly interest rate is over the course of four years.

1,242 x 4 = $4,968.

Therefore, Trey will have earned $4,968 after four years.

To complete this problem, we need to add this to his original balance, or $540.

4,968 + 540 = 5,508

Therefore, Trey would make a total of $5,508 after four years.
