At a fundraiser, Marco's class sold 75% of their 80 baked
goods. How many baked goods did they sell?

Answers

Answer:

Step-by-step explanation:

They sold 60 baked goods because 75% of 80 is equal to 60.

Answer:

60 baked goods

Step-by-step explanation:

To find the answer to this question, you will need to multiply 80 by 75%.

Now this is very simple.

Some calculators will actually give you the option to multiply by a percent. Just type 80×75% and you'll get 60.

There is another way to do this.

You could also just solve 80×.75 due to the fact that .75 is equal to 75%.

What is the perimeter of the triangle

Answers

Answer:30 centimeters

Step-by-step explanation:

The bigger square with an area of 144 cm squared has a perimeter of 100 with each side equal to 25. You find this by seeing that 25 times 25 equals the area of the square. Same thing with the smaller square 5 times 5 equals 25. Now that we have the perimeter for the sides that are connected to the square (25) and (5), multiply those together just as you would with finding the area of a square. (25)(5)=60. Since this is a triangle you divide your answer in half which is 30.

Graph the equation y=−x²−8x−15 on the accompanying set of axes. You must plot 5 points including the roots and the vertex.

Answers

Answer:

Plot these points

(-3,0)

(-5,0)

(-4,1)

(-2,-3)

(-6,-3)

Step-by-step explanation:

Let find the zeros of the equation.

We can factor this equation.

Factor out the -1.

[tex] - 1( {x}^{2} + 8x + 15)[/tex]

Factor using AC method

[tex] - 1(x + 3)(x + 5)[/tex]

Set all the terms equal to zero.

[tex]x + 3 = 0[/tex]

[tex]x + 5 = 0[/tex]

[tex]x = - 3[/tex]

[tex]x = - 5[/tex]

So our x intercepts are -3,0 and -5,0.

To find our vertex, apply the -b/2a.

[tex] \frac{8}{ - 2} = - 4[/tex]

Then

Substitute-4 for x.

[tex]y = - {4}^{2} - 8( - 4) - 15 = 1[/tex]

So our vertex is at (-4,1).

Find some other points like -2 and -6.

To find -2, substitute-2 into the quadratic.

[tex]y = - ( { - 2}^{2}) - 8( - 2) - 15 = - 3[/tex]

So -2,-3.

Since y=-4 is the axis of symmetry

-6,-3

The 5 points which satisfies the quadratic equation y = −x² − 8x − 15 is

( -5 , 0 ) ( -1 , -8 ) , ( -2 , -3 ) , ( 4 , 1 ) , ( -3 , 0 ) and the vertex point is ( 4 , 1 )

What is Quadratic Equation?

A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c=0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.

Given data ,

Let the quadratic equation be represented as A

Now , the value of A is

y = −x² − 8x − 15

On simplifying the equation , we get

y = -1 ( x² + 8x + 15 )

On factorizing the equation , we get

y = -1 ( ( x + 5 ) ( x + 3 )

So , the 2 values for x is -5 , -3

So , the two points are ( -5 , 0 ) and ( -3 , 0 )

The vertex will be -b/2a

Substituting the values in the equation , we get

The vertex = -8/2 = -4

So , when x = -4

y = -1 ( ( x + 5 ) ( x + 3 )

y = -1 ( 1 x -1 )

y = 1

So , the vertex is at the point ( 4 , 1 )

Now , when x = -1

y = -1 ( ( x + 5 ) ( x + 3 )

y = -1 ( 4 x 2 )

y = -8

So , the point is ( -1 , -8 )

Now , when x = -2

y = -1 ( ( x + 5 ) ( x + 3 )

y = -1 ( 3 x 1 )

y = -3

So , the point is ( -2 , -3 )

Hence ,

The 5 points which satisfies the quadratic equation y = −x² − 8x − 15 is

( -5 , 0 ) ( -1 , -8 ) , ( -2 , -3 ) , ( 4 , 1 ) , ( -3 , 0 ) and the vertex point is ( 4 , 1 )

To determine this, you sample the moods of 200 people on a sunny day, 200 people on a rainy day and 200 people on a cloudy day and record whether they were happy or not. You then want to do a chi square test on this data. What are the degrees of freedom?

I heavily pushed the wooden cinnamon colour door open as it screeched on the reeking dusty floor, leaving scraped marks. My blonde hair strands flowed around amid the unfocused lightened landscape, I tightened my toes to the grass, clenched my hair and brushed it out of my face, sighing ecstatically. I waved to my sister and ran off to collect wood. I looked around as animals cluttered around me, getting on with their daily routines. robins chirping, rabbits scurrying, squirrels squeaking and stealing acorns from oak trees, the hedgehog yields a yorn, buttercups, roses, lily pads, OOOOWWWW .

His skin was black. Bleach black as if it was painted, his left eye blue and the other yellow. He pulled me up and asked if I was okay. I'm okay, thanks ''. He gave an amiable aura though he gave a diabolical feeling at the same time. A snake. He wore gold accessories, ripped black pants and tall.
