Answer: AC=108

Step-by-step explanation:

6x=9x-27

9-6=3

27/3=9

x=9

6x9=54

9(9)=81

81-27=54

54(2)=108

AC=108

Richard works at an ice cream shop. Regular cones get two scoops of ice cream; large cones get three scoops. One hot Saturday, R
ExtremeBDS [4]

Answer:

17.55 tubs

Step-by-step explanation:

step 1

Find out the total scoops of ice cream in 234 regular cones and 156 large cones

234(2)+156(3)=936\ scoops

step 2

Find out the weight of the total scoops

we know that

One scoop of ice cream is 3 ounces

so

936(3)=2,808\ ounces

step 3

Convert ounces to pounds

Remember that

1 pound = 16 ounces

so

To convert ounces to pounds divide by 16

2,808/16=175.5\ pounds

step 4

Find out how many ice cream tubs Richard used to make the cones

we know that

A tub of ice cream weighs 10 pounds

Divide the total weight in pounds by 10

175.5/10=17.55\ tubs

How do I graph a function based off the unit circle?
sweet [91]
So if you remember what the normal y = sin(x) function looks like (a wave), y = 2 sin(4x) is just changed a little.

The standard format for sine/cosine function
<span>y = a sin<span>(bx− c)</span> + <span>d

a = amplitude, distance from center of the wave to the highest point. This function a = 2 so the height of the sine wave reaches 2 instead of 1.
"c" and "d" shift the graph left/right and up/down respectively. These equal zero so the sine wave is not shifted.

The range (y-values) is then just the amplitude -2 ≤ y ≤ 2

The domain (x-value) is all real numbers because the wave just keeps going on to infinity in both directions.

2π / |b| = period, distance per wave
this equation b = 4
period is then π/2
this is the distance before a wave repeats.

Graph
     x  |  y
-π/8    -2
    0      0
  π/8    2
3π/8   -2
5π/8    2

see the pattern? I'm using the amplitude or peaks and bottoms of the wave y = 2 and -2  then using the x-distance between like points is the period so you add π/2

(π/8 , 2) 
+ π/2
(5π/8 , 2)

Same for the minumums of the wave (y = -2)
(-π/8 , -2)
+ π/2
(3π/8 , -2)

Hope this helps, otherwise there are youtube videos you can watch or try an online graphing calculator like Desmos.com

Jason has decided to sell one of his baseball cards. The card is valued at $51.00. The store is only offering Jason $29.00. How
sveta [45]
Well, just take the difference, 51-29, and 22 is how much less his card it being valued at. Or you can do 29-55, which would be -22, showing the amount and that it's valued less.

At The Old Home Fill'er Up and Keep on a-Truckin' Cafe, Mavis mixes two different types of coffee beans to produce a house blend
Alex Ar [27]

There are 45 pounds and 30 pounds of each type respectively.

Step-by-step explanation:

Since we have given that

Cost of first type = $2 per pound

Cost of second type = $7 per pound

Cost of mixture = $4 per pound

So, we need to find the quantity of each type to make 75 pounds of a blend.

We will use "Mixture and Allegations":

  First type         Second type

       2                         7

                     4

---------------------------------------------------

     7  - 4       :              4 - 2

      3             :                2

So, Quantity of first type would be

\dfrac{3}{5}\times 75=3\times 15=45\ pounds

Quantity of second type would be

\dfrac{2}{5}\times 75=2\times 15=30\ pounds

Hence, there are 45 pounds and 30 pounds of each type respectively.
