Dexter makes 20 cookies. He eats 6 of the cookies and takes the rest to school. What percentage of the cookies does he take to school?

Answers

Answer:

70%

Step-by-step explanation:

If he makes 20 cookies, and eats 6 of them, then we have 14 cookies left. So we use the equation 14/20 = x/100. We then cross multiply so 14 * 100 and 20 * x. That gives us 20x = 1400. Divide 1400 by 20 and you get 70. So it's 70% since we used 100% in the equation. I hope this helped :)

The percentage of increase or decrease can be found by multipyling the ratio of increase or decrease and the initial value to 100.

What is percentage?

A percentage is a value that indicates 100th part of any quantity.

To convert percentage into a fraction it is divided by 100.

Given that,

The total number of cookies made by Dexter = 20

The number of cookies eaten by him = 6.

Now, the number of cookies he takes to school is given as,

(total number of cookies  - number of cookies eaten)

= 20 - 6

= 14

The percentage of cookies is given as,

(total number of cookies  - number of cookies eaten) ÷ (total number of cookies) × 100%

= 14 ÷ 20 × 100%

= 70%

Hence, Dexter takes 70% of cookies with him.

Consider functions g and h
g(x)=3(x-2)+1
h(x)=-2x+14

What is the value of (h ∘ g)(4)?

-6
0
82
13

Answers

Answer:

0

Step-by-step explanation:

Remark

It is not at all obvious which function goes where.  The way to write this so you can tell is

h(g(x))

That means that wherever you see an x in h(x), you put g(x) there.

Formula

h(x) = 2x + 14

h(g(x)) = -2 * g(x) + 14

Solution

h(g(x)) = -2 * [3(x - 2) + 1] + 14

h(g(x)) =-2 [ (3x - 6) + 1 ] + 14

h(g(x)) =-2 [ 3x - 6 + 1) ] + 14

h(g(x)) =-2 [ 3x - 5 ] + 14

h(g(x)) = -6x + 10 + 14

h(g(x) = -6x + 24

h(g(4)) =-6*4 + 24

h(g(4))  = 0

Find the points which divide the line segment joining the points (0, -3) and (7,1) in the ratio 2:3
internally and externally

Answers

Answer:

Known two points, list function expression, use

[tex]y-y_{0}=k(x-x_{0})[/tex]

[tex]k= \frac{y_{2} -y_{1\\}}{x_{2} -x_{1} }[/tex]

The function expression is

[tex]y=\frac{4}{7}x-3[/tex]

It is known that the cross section of two points is 7, so the point of 2:3 is 14 / 5, that is, 0 + 14 / 5 is the abscissa of the point, which is substituted into the original equation to get y = - 7 / 5.

So the result is   [tex](\frac{14}{5} ,-\frac{7}{5} )[/tex]

A square wall is covered with sqare tiles. There are 85 tiles altogether along the two diagonals. How many tiles are there on the whole wall?​

Answers

Answer:

There are 1849 tiles on the whole wall.

Step-by-step explanation:

If there are 85 tiles along the two diagonals, we can use the following rule:

[tex]\frac{85+1}{2}=43[/tex]

So we have 43 tiles in the first diagonal and 85-43 = 42 in the second diagonal.

Now, as we have a square the side will have 43 tiles so the total area will be cover with:

[tex]A=43*43=1849[/tex]

Therefore, there are 1849 tiles on the whole wall.

My last math question of the day! Help me out!

What equation can be used to find B, the number of points scored!

Thank you!

Answers

Answer:

A

Step-by-step explanation:

Let b represent the number of points Ben scored.

We know that Lori scored 26 points.

This amount is two less than four times what Ben scored.

Four times what Ben scored will simply be 4b.

And two less will be 4b - 2.

This is equivalent to Lori's score.

So, we can write that:

[tex]4b-2=26[/tex]

Hence, our answer is A.

Answer:

I believe it is A

Step-by-step explanation:

Since in this problem you would want to find b, which is stated the is almost 4 times 26... however is 2 less. The other options are wrong since you would want a bigger number, not a smaller one... Hopefully this is helpful

what is the value of y in the following system of equations? explain how you found your answer

Answers

Step-by-step explanation:

I've used elimination method over here but it can also be done by using substitution.

2x + 3y = 6
2x + y = -2

Solve the second equation for y and substitute into the first equation

2x + y = -2
y = -2x - 2

2x + 3y = 6
2x + 3(-2x - 2) = 6
2x - 6x - 6 = 6
-4x - 6 = 6
-4x = 12
x = -3

Plug back in to solve for y
2x + y = -2
2(-3) + y = -2
-6 + y = -2
y = 4

Plug into other equation to check
2x + 3y = 6
2(-3) + 3(4) = 6
-6 + 12 = 6
6 = 6 :)

The Warriors beat the Hawks in basketball. The Warriors scored six less than triple the Hawk's point total. The combined score for the two teams was 66. How many points did each team score?

Answers

Answer:

Warriors scored 48 points and Hawk score 18 points.

Step-by-step explanation:

The Warriors beat the Hawks in basketball.

Let hawk's point be h.

Warriors score,

w=3h-6

w-3h=-6 ...(1)

The combined score for the two teams was 66.

w+h=66 ...(2)

Subtract equation (1) from (2).

w+h-(w-3h) = 66-(-6)

w+h-w+3h = 72

4h = 72

h = 18

Put the value of h in equation (2).

w+18=66

w = 48

So, Warriors scored 48 points and Hawk score 18 points.
