We have the next information:

1/10 of the T-shirts sold were size extra

1/8 were extra small

Now, we need to find which fraction represents a higher number.

Convert to decimal each fraction:

and

Hence, 1/8 is greater than 1/10. So, more extra small tshirts were sold.

The formula for rotation 270° counterclockwise is: A(x,y) ---> A'(y,-x)

If the point is A(-5,2) then the answer would be: A'(2,-(-5)) = A'(2,5) after rotating 270° counterclockwise.

Bryson:

Already made PS4's = 30

Number of PS4's per hour = 5

Fady :

Number of PS4's per hour = 8

x= hours

y= ps4's

Bryson equation:

y= 30+5x

The number od PS4's made by Bryson (y), must be equal to the sum of the already made PS4's (30) and the product of the number of PS4's made per hour (5) and the number of hours (x)

Fady:

y= 8x

System of equations:

y= 30+5x

y= 8x

Solution

Given 18,20,18,2,7

The variance formula is given as;

According to the given data we have the following equation:

y + 10 = -15​

To solve the variable y of the equation above we would make the following:

y + 10 = -15​

We would move the number 10 to the other side, so it would change its sign.

y=-15-10

Finally add the numbers So:

y=-25

The result of the y would be -25

ANSWER

f(1) = 8

EXPLANATION

In this problem, we have to evaluate the function f(t) in t = 1. To do so, substitute t with 1 in the equation, and solve,

Hence, f(1) = 8.

There are 245 bottles to fill the milk.

What is Division method?

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.

For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

A farmer gets 24.5 L of milk from each of his cows per day.

And, He milks all five cows and pours the milk equally into 0.5-L bottles.

Now,

Since, A farmer gets 24.5 L of milk from each of his cows per day.

And, He milks all five cows.

So, The total amount of milk = 24.5 x 5 L

                                            = 122.5 L

Since, He pours the milk equally into 0.5-L bottles.

So, The number of bottles = 122.5 L ÷ 0.5 L

                                         = 245

Thus, There are 245 bottles to fill the milk.

The sequence of numbers uses 21 numbers whereas each number in the sequence must be a factor or multiple of the previous number is 1, 7, 21.

We are given numbers from 1 to 24.

We need to find the longest sequence using the number 21 such that each number in the sequence must be a factor or multiple of the previous number.

Let the last number be 21.

The previous number of 21 must be a factor or multiple of 21.

From the given numbers we can only choose 7 as it is a factor of 21.

So, the sequence will be ...., 7, 21.

Now,

The previous number of 7 must be a factor or multiple of 7.

From the given numbers we can only choose 1 as it is a factor of 7.

So, the sequence will be 1, 7, 21.

There is not any previous number to 1.

So, our final sequence will be 1, 7, 21.

Thus, the sequence of numbers uses 21 numbers whereas each number in the sequence must be a factor or multiple of the previous number is 1, 7, 21.

The equation for a straight line can be found if its slope and coordinate of the point it passes through is given. The equation for the given graph is c = 60w. The correct answer is option C.

A straight line can be written in the form of equation as, y = mx + c.

Two straight lines intersect each other only at one point.

When two straight lines are parallel to each other the angle between them is zero.

Given that,

The cost of food delivery is taken as c.

The number of weeks is w.

Since the graph given in the problem is a straight line, in order to find its equation its slope has to be found as follows,

From the graph, it is clear that at w = 2, c = 120.

Now, there are two points for the given straight line as (0, 0) and (2, 120).

Thus, the slope is given by (120 - 0) / (2 - 0) = 60

Then the equation for the straight line is,

(c - 0) / (w - 0) = 60

=> c = 60w

Hence, the equation of the given graph is c = 60w.

We need to calculate the following quotient:

We know that:

Then:

Using the distributive property of multiplication, we factor the 4n³ term of the numerator:

We can see in the graph that the y-intercept is equal to +5. According to that, the correct options could be second and third options.

The line has a positive slope and the third option has a positive slope (1/2), therefore, this is the correct answer. (Since the second option has a negative slope (-1/2)).

The answer is y= 1/2x + 5

50% means 50/100 = 0.5

300% means 300/100 = 3

Now,

A number, let it be "100" (you can take any number, the answer would be the same).

It is decreased by 50%, so

100 - (0.5)(100) = 50

Then, it is increased by 300%, so

50 + 3(50) = 200

So, we started off with 100 and now we're at 200.

The questions asks ORIGINAL is what percent of FINAL.

So, original was 100 and final is 200, essentially:

100 is what percent of 200??

100/200 = 0.5

In percentage,

0.5 * 100 = 50 %

J is the correct choice.

To transform a percentage to a simple fraction we divide the number by a 100, then we have:

Therefore 48% in simple fraction is equal to 12/25

We are given the slope m=-1 and the point (0,-2)

The point-slope form of the line is:

y - k = m(x - h)

Substituting:

y - (-2) = -1(x - 0)

Operating:

y +2 = -1(x - 0)

This was the point-slope form of the line

Rewriting in slope-intercept forn:

y +2 = -x

Subtracting 2:

y = -x - 2

That is the slope-intercept form of the line
