Answer:

Sessions needed= 12

Step-by-step explanation:

Giving the following information:

Total hours= 12 hours

Practice= 3/4= 0.75 of an hour

Already practiced= 3 hours

<u>First, we need to determine how many minutes does she practice each session:</u>

Minutes per session= 0.75*60= 45 minutes

<u>Now, we divide the total practice in minutes required for the minutes per session:</u>

Sessions needed= (9*60) / 45

Sessions needed= 12

A test of 10 different types of candy are being tested. If a person is given 6 of the candies to taste how many combinations are
ASHA 777 [7]

There are 210 different possible combinations

<h3>How to determine the number of possible combinations?</h3>

The given parameters are:

  • Types of candy, n = 10
  • Candies to taste, r = 6

The number of possible combinations is calculated using:

Combination = nCr

This gives

Combination = 10C6

Apply the combination formula

Combination = (10!)/((10 - 6)!6!)

Evaluate

Combination = 210

Hence, there are 210 different possible combinations

F(x)=20-x^2+8x<br> what are the minimum and maximum points and the axis of symmetry?
-Dominant- [34]
Vertex aka max or min point is found by -b/2a in form
f(x)=ax^2+bx+c
f(x)=-1x^2+8x+20
vertex x value is -8/(2)(-1)=-8/-2=4
input back to find y value
f(4)=-(4^2)+8*4+20
f(4)=-16+32+20
f(4)=36
max (since the graph opens down) is (4,36)
axis of symmetry is the x coordinate


max is (4,36)
axis of symmetrry is x=4

Explain the relationship between multiplying and divding by 10, 100, and 1,000 and moving the decimal point to the right or to t
MakcuM [25]
Here are examples which will explain:
5 x 10= 50 therefore what we did here was 5.0 and we just moved the decimal to the right by making it a bigger number because it is multiplication

6x100= 600, here we also moved the decimal to the right 2 times because there are 2 zeros

7x 1000= 7000 we moved the decimal 3 times to the right because it has 3 zeros

Now for division

If we do 5 divided by 10 that would be 0.5 because there is one 0 and that means we move the decimal to the left once.

6 divided by 100= 0.06 we moved the decimal to the left 2 times because there are 2 zeros so basically in conclusion we do the same thing in division and multiplication with 10,100,1000,10000 but we just move the decimal to the left in division and move decimal to the right in multiplication.

Hope that helps!
