Answer:
The answer is <u>A) 36</u>
Step-by-step explanation:
Since 40% is equal to 0.4 of 1
You would multiply 90 by 0.4
Which is 36, which would give you answer A)
For h(x) = -7x + 10, x =1
For r(x) = 4/5x+ 7 , x = -15
Step-by-step explanation:
in order to find the value of x on which the functions will have given values, we will put the functions equal to the given values
So,
<u>h(x) = -7x + 10; h(x) = 3</u>

Dividing both sides by -7

<u>r(x) = 4/5x+7; r(x) = -5</u>

Answer:</h2>
<u>The cost would be </u><u>$15.86</u>
<h2>
Step-by-step explanation:</h2>
The cost of 1 steak is $6.10
The cost of 2 3/5 steaks will be
Cost of 2 3/5 steaks = 6.10 * 2 3/5
Cost of 2 3/5 steaks = $15.86
To get the volume of an object, one of the oldest techniques is to fill a container with water of which we know the volume (in this case 85mL), and drop the object in. The water will rise and show a new volume (225mL). If we subtract the old volume (85) from the new volume (225), we will get the volume of the object (225 - 85 = 140).
The first thing we must do in this case is to define variables:
t = time to write the words
v = write speed.
w = number of words.
The correct expression is:
t = w / v
By substituting we have:
t = 1000/6
t = 166.6666667
Rounding:
t = 167 minutes
Answer:
The correct expression is:
t = w / v
The time is:
t = 167 minutes
