Answer:

Answer is 11.

Step-by-step explanation:

Maria used two loaves of bread , One loaf is equal=2 1/4 cups so two becomes 2 ×2 1/4= 9/2

Maria makes the remaing 48 muffins of the flour left so,

One muffin is equal 3 1/4 cups so two becomes 2×3 1/4=13/2

Add both of them

9/2+13/2=11

Approximately how much do i save per bottel of juice if i buy a pack of 8 rather than a pack of 6

Korolek [52]

Answer: Your question is missing information but this is what you do to answer your question step by step

B = Cost of 8 pack / 8 bottles = $ Cost of 8 pack/ 8 =$ ____ per bottle

A = Cost of 6 pack/ 6 bottles = $ Cost of 6 pack/ 6= $ ____ per bottle

then do a simple subtraction A -B = savings

Step-by-step explanation: Information is incomplete

if an 8 pack cost $16

If the 6 pack cost $15

All you do is a simple subtraction after calculations

Cost of 8 pack / 8 bottles = $16/8 =$2 per bottle

Cost of 6 pack/ 6 bottles = $15/ 6= $2.50 per bottle

in my example

You would save $ 0.50 per bottle by purchasing the 8 pack

Which statement describes a unit rate? Group of answer choices Sara is reading 97 words in 1 minute. Sara ate 3 crackers and 1 a

castortr0y [4]

Answer:

97 words in 1 minute

Step-by-step explanation:

A unit measure is so many somethings done usually per unit time. Examples

1 orange in 1 minute.
10 tomatoes per tomato plant
50 miles in one hour
10 cookies per week

3 crackers and 1 apple is not. For ever apple, she ate 3 crackers would be

1 cookie is not. It is not per anything.

Driving 16 miles is not. Again, it is not per anything.

The answer is 97 words in 1 minute.

21 POINTS!! Thank you so much!! There’s also things on my page worth lots points points as well! So if you could help with those

Art [367]

Answer:

Second one

third one

fifth one

last one

Step-by-step explanation:

Based on the x intercepts we can write

a(x+1)(x-5)

where a is some constant

solve for a by plugging in some coordinates

let's plug in (1,-8)

-8=a(1+1)(1-5)

-8= -8a

a=1

therefore the quadratic is (x+1)(x-5)

expand this

x²-4x-5

To find out where something is decreasing/increasing it's easiest to take the first derivative

x²-4x-5= 2x-4

set this equal to 0

2x-4=0

2x=4

x=2

Which means that our two intervals are

(-∞,2)U(2,∞)

plug in any values in the intervals to see whether or not the function is increasing/decreation

Let's plug in 0 for (-∞,2)

2(0)-4

-4

It's negative so it's decreasing on this interval

DO the same thing with the other one

let's plug in x=3

2(3)-4

this is positive so it's increasing on this interval

Go back to the critical value of x=2 and plug this into the equation to find the max/min

(2+1)(x-5)= -9

This is a minimum because the cofeccient for the degree is positive

For the limit one notice that we have a positive, even degree which means the end behavior is positive, positive

what this means is as x approaches negative infinity it's infinity

and as x approaches infinity it's infinity

Look down below for question:

Area of ABC : AB*AC/2

the maximum of the parabola is reached at x=-4/(2*(-1))=2 hence A is at (2,0) and B is at (2,(-2)^2+4*2+C)=(2,12+C)

C is the second root (x-intersect), which we can find :

determinant1 : D=16-4*(-1)*C=4(4+C) thus the second root is at x= $\frac{-4-\sqrt{4(4+C)}}{-2}=2+\sqrt{4+C}$

Hence the area of the triangle is $AB*AC/2=(4+C)*(2+\sqrt{4+C}-2)/2=(4+C)\sqrt{4+C}/2=32$ hence $(4+C)\sqrt{4+C}=64$ .

We remark that $64=16*4=16*\sqrt{16}$

Hence 4+C=16 thus C=12
