Answer:

The total number of cookies is 90

Step-by-step explanation:

As, they said 40% of the total number of cookies is 36, we will take the total as "x"

= 40% of x = 36

40/100 X x = 36

40x = 36 x 100

40x = 3600

x = 3600/40

x = 90

So total cookies she baked = 90

Let's check!

So 40% of 90 need to be 36

So,

40/100 x 90 = 3600/100

= 36

So therefore, total number of cookies = 90

Answer:

The nth term of the sequence will be:  n²/n+1

Step-by-step explanation:

Given the sequence

1/2 , 4/3 , 9/4 , 16/5

The values in the numerator are:

2, 3, 4, 5

It is clear that every successive value in the numerator can be determined by adding 1 to the previous value.

i.e.

3 = 2+1

4 = 3+1

5 = 4+1

Thus, the nominator contains the sequence rule: n+1

The values in the denominator are:

1, 4, 9, 16

It is clear that every value in the denominator is the square of the sequence number.

i.e.

1 = 1²

2 = 2²

3 = 3²

4 = 4²

5 = 5²

so

The denominator defines the rule n².

Thus, the nth term of the sequence will be:  n²/n+1

it has no solution, because the D is negative

Answer:

12 [tex]units^{2}[/tex]

Step-by-step explanation:

All you have to do is do each shape then add them all up

small triangle:

a = b * h/2

a = 2 * 2/2

a = 4/2

a = 2

The area for the small triangle is 2

Sqaure:

a = b*h

a = 2*2

a = 4

The area for the sqaure is 4

Large triangle:

a = b*h/2

a = 6*2/2

a = 12/2

a = 6

The area for the larger square is 6

Now we add up all of the areas

2 + 4 + 6 = 12

The area for that shape is 12 [tex]units^{2}[/tex]

Hint: We divide by 2 for the triangles bc it's half a shape not a full rectangle of square...

Hope this helped!

Answer:

x=-2

Step-by-step explanation:

Let's solve your equation step-by-step.

3x+9=x+5

Step 1: Subtract x from both sides.

3x+9−x=x+5−x

2x+9=5

Step 2: Subtract 9 from both sides.

2x+9−9=5−9

2x=−4

Step 3: Divide both sides by 2.

2x /2=-4/2

x=−2

Answer:

2 1/4 cups

Step-by-step explanation:

3/4 is for one cake, if Carlos is making 3 times that amount of cakes, Carlos needs three times the amount of sugar. So, our equation is:

3/4 x 3 = 9/4

9/4 = 2 1/4 or 2.25

So, Carlos needs 2 1/4 cups of sugar for 3 cakes

The one on the top right side

Step-by-step explanation:

A graph with a negative slope is a graph that "decreases" in y value when the x values "increases".

I'm the top right graph, the y value changes from 8 to 6, the x value changes from 0 to 4.

Also if you trace the 1 on the x axis upward until it touches the graph , you'll see that , that's where you'll see the 6 on the y axis. That's why The graph passes through (1,6).

Answer:

The scale factor of a dilation is 3.

Step-by-step explanation:

Given the length ST of the rectangle RSTU

The length ST of the rectangle = 8 units

It is clear that the corresponding length S'T' = 23 is 3 times the length of the original length ST = 8

i.e.

S'T' = 3(ST)

S'T' = 3(8)      ∵ ST = 8

S'T' = 24

It indicates that the RSTU has been dilated by a scale factor of 3.

As the scale factor 3 > 1, it also indicates that the dilated rectangle R'S'T'U is enlarged.

Therefore, the scale factor of a dilation is 3.

Answer:

A

Step-by-step explanation:

To know the distance between the two on a number line, we subtract both numbers from each other

Since the absolute value will give the same result irrespective of the number we used first, we can see that it is the first option that would give the needed results

This means that option A is our answer
