A school assembly had 600 students in attendance, and 35% of them were first-graders. How many first-graders were at the assembly?

can u also list the formula on how to do this while ur at it pls and ty

Answers

Answer:

210 Were First Graders

Step-by-step explanation:

35 percent of 600 is the same as 35 per hundred of 600. We can therefore make the following equation:

35/100 = X/600

To solve the equation above for X, you first switch the sides to get the X on the left side, then you multiply each side by 600, and then finally divide the numerator by the denominator on the right side to get the answer. Here is the work to illustrate:

35/100 = X/600

X/600 = 35/100

X*600/600 = 35*600/100

X = 21000/100

X = 210

The work above shows the long way to explain how to calculate 35 percent of 600 in order to give you a foundation and better understanding of how to calculate percentage. In the future, you could use this simplified formula:

(Y * P)/100

In our problem "What is 35 percent of 600?", Y is 600 and P is 35:

(600 * 35)/100 = 210

And once again you see that the answer is 210.

Answer:

210 kids

Step-by-step explanation:

So the formula is basically part over whole is equal to x/100%

So for here it would be x/600 = 35/100

Solve that and you will get 210

For the top section, we can portion out 20 x 8 = 160.

Next, directly in the middle is a 5 x 5 square = 25.

Finally, we have a right triangle with dimensions 10 x 20 so the area would be 10 x 20 / 2 = 100.

160 + 25 + 100 = 285.

3/4c-7/12+7/24c+2/3-1/6c

Answers

Answer: 7/8c + 1/12

Explanation: separate the c terms and the non-c terms. 3/4c + 7/24c - 1/6c = 7/8c

-7/12 + 2/3= 1/12

therefore, it’s 7/8c + 1/12

The simplification of the given expression (3/4)c - 7/12 + (7/24)c + 2/3 - (1/6)c is (21/12)c + 1/12.

What is an expression?

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

As per the given expression,

(3/4)c - 7/12 + (7/24)c + 2/3 - (1/6)c

Combined likely terms,

⇒ (3/4)c + (7/24)c - (1/6)c - 7/12 + 2/3

⇒ (3/4 + 7/24 - 1/6)c + 2/3 - 7/12

⇒ [(18 + 28 - 4)/24]c+ (8 - 7)/12

⇒ (42/24)c + 1/12

⇒ (21/12)c + 1/12

Hence "The simplification of the given is (21/12)c + 1/12".

Question about finding intercepts from a table. Hope someone can answer!

Answers

Basically you have to use the table to find the equation of the line, then plug in a point into x and y and the b you will get is your y-intercept.

Now if you are familiar with the equation of a line in slope intercept form, it will look like this: y=mx+b. Here the ‘m’ is the slope and the ‘b’ is your y-intercept. What you need to do is use any two points given from the table and find the slope. To do that follow the steps below:

1. Pick two points. Let’s take the first two.
(-28, -54) And (-21, -40)

2. Subtract the two y values, -40 - (-54) = 14
3. Subtract the two x values, -21 - (-28) = 7
4. Now take your answer from step 2 and divide it by your answer in step 3. This will be 14/7, which will be 2.

Your answer from step 4 is your slope, or ‘m’.
(That series of steps was basically change in y over change in x, you can look that up if you are still confused)

Now that you know m, your incomplete equation will be this:
y=2x+b.

Next you will pick any point from the table again, and replace it with x and y in the equation. Let’s pick the second point, (-21,-40)

Plug this in: -40 = 2(-21) + b
Solve for b and you will get your answer.
-40 = -42 + b
b=2
Your answer is 2, that is the y intercept.
(The full equation of the line from that table would be y=2x+2)

The distance around the oval track would be 556.9 m which is the sum of the perimeter of the square and the circumference of the semi-circles.

What is the Circumference of a circle?

The Circumference of a circle is defined as the product of the diameter of the circle and pi.

C = πd

where 'd' is the diameter of the circle

We have to determine the distance around the track

The required distance is equal to the sum of the perimeter of the square and the circumference of the semi-circles.

A middle school has an oval track with the dimensions shown.

Here the length of a side of the square = 78 m

And the diameter of the circle = 78 m

the distance around the track = perimeter of  square + circumference of the circle

the distance around the track = 4 × 78 + π × 78 / 2 + π × 78 / 2

the distance around the track = 4 × 78 + π × 78

the distance around the track = (4 + π) × 78

the distance around the track = (4 + 3.14) × 78

the distance around the track = 7.14 × 78

the distance around the track = 556.9 m

Therefore, the distance around the oval track would be 556.9 m.

Answers

Answer:

A

Step-by-step explanation:

First, I'm going to work out the hourly wages for the 2 weeks.

$8 x 70hours = $560

(8 x 7 = 56 x 10 = 560)

Next, work out the commision.

10% of $1612

1612 ÷ 10 = 161.2

Finally, add together both the hourly wages and commision.

161.2 + 560 = 721.2

Round it down to a whole number.

721 , Add on the dollar sign.

It's answer A, $721.
