Calculate the difference between 1/5 and 5/8
A: 1
B: -17/40
C: 1 1/3
D: -17/30
Answer:
The difference between means we are subtracting. 1/5 - 5/8 = -0.425 = -17/40
Solution:
Since 5/8 is greater than 1/5, it is a negative fraction.
Hope this helps!
Answer:
B. -17/40
Step-by-step explanation:
Given F(x) =3x+2 and g(x) = 2x2 , find the following composite functions:
a. (g*f)(3)
b. (f*g)(x)
Answer:
b. (f*g)(x)
Step-by-step explanation:
Set up the composite result function.
g ( f ( x ) )
Evaluate
g (f ( x ) )
by substituting in the value of
f into g . g ( 2 x 2 + 3 ) =3 ( 2 x 2 + 3 ) − 2
Simplify each term.
g ( 2 x 2 + 3 ) = 6 x 2 +9 − 2
Subtract
2 from 9 . g ( 2 x 2 + 3 ) = 6 x2+ 7
Answer: B
Step-by-step explanation:
Set up the composite result function.
g ( f ( x ) )
Evaluate
g (f ( x ) )
by substituting in the value of
f into g . g ( 2 x 2 + 3 ) =3 ( 2 x 2 + 3 ) − 2

The Cost C (in dollars) of making n watches is represented by C=15n+85. How many watches are made when the cost is $385?
Answer:
The number of watches made is 8
Step-by-step explanation:
SO the equation is C=15n+85 where C is the total cost and N is the amount of watches
1)plug in C
385=15n+85
2)move 85 to the other side so it would become -85
385=15n+85 → 385-85=15n → 100=15n
3)divide 15 from both sides
100/15=15n/15 → 25/3=n
since the number of watches can't be a fraction, we round to the lowest number which is 8(24/3)
Could somebody please help me find the answers for 'x' for these pictures?
**Please let me know which one you solved along with the answer**
Answer:
Pic 1: [tex]x=31[/tex]
Pic 2: [tex]x=20[/tex]
Step-by-step explanation:
Picture 1:
[tex]2x+x-3=90\\3x-3=90\\3x=93\\x=31[/tex]
First, add the 2x and x together for 3x
Then add 3 to both sides of the equation
Finally, divide each side by 3.
Picture 2:
[tex]7x+x+20=180\\8x+20=180\\8x=160\\x=20[/tex]
First, add 7x and x together for 8x
Then, minus 20 from both sides of the equation
Finally, divide each side by 8.
Step-by-step explanation:
First picture
We can make an equation with this
2x+x-3=90
3x=93
x=31 degrees
Second picture
We can make and equation
7x+x+20=180
8x=160
x= 20

Mr. Reynolds is a rancher. He started with a 150 cows in his herd. Due to a hole in his fence, he now has 120 cows in his herd. By what percentage was the number of cows in Mr. Reynold's herd reduced?
Answer:
20%
Step-by-step explanation:
Therefore, the percentage of the number of cows in Mr. Reynold's herd reduced is [tex]20[/tex] %.
What is the percentage?
A percentage is a number or ratio expressed as a fraction of [tex]100[/tex]. It is often denoted using the percent sign, "%".
Here given that,
Mr. Reynolds is a rancher. He started with a [tex]150[/tex] cows in his herd. Due to a hole in his fence, he now has [tex]120[/tex] cows in his herd.
Number of cows Mr. Reynolds have
[tex]\frac{120}{150}[/tex] ×[tex]100=80[/tex] %
So, the number of cows Mr. Reynolds reduced is
[tex]100[/tex] % - [tex]80[/tex] % = [tex]20[/tex] %
Hence, the percentage of the number of cows in Mr. Reynold's herd reduced is [tex]20[/tex] %.

Answer:
yes
Step-by-step explanation:
7 weeks * 7 days per week = 49 days49 days * 2 meals per day = 98 total meals98 meals * 31 grams per meal = 3038 grams after 7 weeksAnswer: Yes, he will meet his goal of eating 3,000 grams of protein in 7 weeks.
Step-by-step explanation: So for the top part your answer is supposed to be 4400.2 grams of protein in 7 weeks. You can get that by adding up the grams of protein for each type of food on the chart. Then you multiply that by 2 to get the amount they will be eating for 1 day which is 89.8. After that, because you have to solve for how much they will be eating for 7 weeks, you will have to multiply 89.9 x 49(days in total). To get you to the answer 4400.2. Now you have your answer for the second part of the problem. Yes, he will meet his goal of eating 3,000 grams of protein in 7 weeks.

Point R is at (2, 1.2) and Point T is at (2, 2.5) on a coordinate grid. The distance between the two points is ____. (Input numbers and decimal point only, such as 8.2.)
Answer:
we can see that the x or the first number in both are 2 so there is no distance there, where there is a distance is the y which to find out we can just do 2.5-1.2=1.3
the distance between the two points is 1.3
Which graph shows the correct solution to the inequality below?
Answer:
Third Option
Step-by-step explanation:
3x + 18 > 6x - 9
We have to find the value of x for this
Subtract 18 from both sides to leave 3x alone
3x > 6x - 27
Subtract 6x from both sides to be able to find the value of x
-3x > -27
Divide by -3 on both sides
x > 9
The answer would be the third option, since X is anything greater than 9

Transformation is a method required to resize or change the orientation of a given shape or figure. The required answer is:
i. Statements b and d would map Shape l onto Shape IIii. Statements a, c, e, and f does not map Shape l onto Shape IITransformation is a method required to resize or change the orientation of a given shape or figure. The types of transformation are translation, reflection, rotation, and dilation.Translation is a method that requires moving every point in a given shape in the same direction and same unit.
Reflection is a method that involves flipping a given figure about a given reference point or line. Rotation is a method that required turning a given figure at an angle about a reference point. Dilation is a method in which the length of the sides of the figure is either increased or decreased.Thus the answers to the question are listed as follows:
a. a reflection across the y-axis, followed by a 90° clockwise rotation about the origin, and then a translation left 18 units.
