Answer:
The coffee Leah has left in percentage is 68.18%
Step-by-step explanation:
Given data
Total available coffee = 22 ounces
Amount She took out = 7 ounces
Let us carry out a simple subtraction arithmetic to find out the remainder
Hence remaining coffee = 22-7= 15
To expressing the remainder as a percentage we have
(15/22)*100=0.6818*100
= 68.1818%
To the nearest hundredths we have
= 68.18%
Answer: 68.18%
Step-by-step explanation:
Leah has a 22 ounce coffee and she drinks 7 ounces of the coffee. This means she will have:
22 - 7 = 15 ounces left.
The percentage of ounces of coffee Leah has left of her coffee will be the number of ounces left divided by the total number of ounces of coffee multiplied by 100. This will be:
= 15/22 × 100
= 0.6818 × 100
= 68.18%
The percentage of coffee Leah has left is 68.18%.

Can the sides of a triangle have lengths 9.2, 7.8, and 2.1?
Step-by-step explanation:
9.2 + 7.8 = 17 > 2.1
7.8+2.1= 9.9> 9.2
9.2+2.1= 11.3 > 7.8
Since, sum of any two sides is greater than the third side, a triangle can have these lengths

12 + x = 0.80(x + 20)
Solve the linear equation
Answer:
20
Step-by-step explanation:
12+x=0.8(x+20)
Divide both sides by 0.8:
15+1.25x=x+20
Subtract x from both sides:
0.25x+15=20
Subtract 15 from both sides:
0.25x=5
Multiply both sides by 4:
x=20. Hope this helps!
Answer:
x = 20
Step-by-step explanation:
12 + x = 0.80(x + 20)
Distribute the 0.80 on the right side.
12 + x = 0.8x + 16
Subtract 0.8x from both sides.
12 + 0.2x = 16
Subtract 12 from both sides.
0.2x = 4
Divide both sides by 0.2.
x = 20

The reciprocal parent function is translated 5 units right and 3 units up. Write an equation to represent the new function.
Transformations:
y=ax-h+k
Answer:
The new function is [tex]y=\frac{1}{x-5}+3[/tex] , where x ≠ 5
Step-by-step explanation:
The reciprocal parent function is [tex]f(x)=\frac{1}{x}[/tex] , where x ≠ 0
The translation of f(x) to the right h units is f(x - h)
The translation of f(x) up k units is f(x) + k
The translation of f(x) to the right h units and up k units is f(x - h) + k
∵ The equation of the reciprocal parent function is [tex]y=\frac{1}{x}[/tex]
∵ The function is translated 5 units right
∴ h = 5
- That means 5 is subtracted from x ⇒ (x - 5)
∵ The function is translated 3 units up
∴ k = 3
- That means y added by 3
∴ [tex]y=\frac{1}{x-5}+3[/tex]
The new function is [tex]y=\frac{1}{x-5}+3[/tex] , where x ≠ 5
Randy went to the store and brought a shirt that cost $42.00 before taxes and discount. The shirt was on sale for a discount of 20% before tax. The sales taxes was 3%. What did randy pay for the shirt after discount and tax
Answer:
Step-by-step explanation:
The 20% discount amounted to ...
0.20 × $42.00 = $8.40
so the price before tax was ...
$42.00 -8.40 = $33.60
The tax amount is 3% of this value, so is ...
0.03 × $33.60 = $1.008 ≈ $1.01
So the total price paid for the shirt was ...
$33.60 +1.01 = $34.61
Randy paid $34.61 for the shirt after discount and tax.
___
Alternate solution
You can realize that the 20% discount means that Randy will pay 80% of the original price of the shirt. Similarly, the 3% added tax means Randy will finally pay 103% of the discounted price. Then the total price Randy pays is ...
$42.00×0.80×1.03 = $34.608 ≈ $34.61

Each student receives one of 4 calculator models and one of 3 types of ruler. How many possible outcomes are there if a student gets one ruler and one calculator?
Answer:
24 possible outcomes
Step-by-step explanation:
Combination has to do with selection. For example, if r object is selected from a pool of n objects, the number if possible ways can be expressed according to the combination formula:
nCr = n!/(n-r)!r!
Applying this in question, if each student receives one of 4 calculator models and one of 3 types of ruler, the number of ways this can be done is:
4C1 × 3C1
4C1 = 4!/(4-1)!1! {If a student gets one calculator)
4C1 = 4×3×2/3×2
4C1 = 4ways
3C1 = 3!/(3-2)!1! {If a student gets a ruler}
3C1 = 3×2/1
3C1 = 6ways
Total number of possible outcomes if a student gets one ruler and one calculator will be 4×6 = 24ways

Kyleigh put a large rectangular sticker on her notebook. The height of the sticker measures 16 centimeters. The base is half as long as the height.The area of the notebook that the sticker covers is ____________ square centimeters.
Answer: The area of the notebook that the sticker covers is 128 cm^2
Step-by-step explanation:
The equation for the area of a rectangle should be:
[tex]A=bh[/tex]
-The height of the stickers measures 16 cm:
[tex]height = 16cm[/tex]
-So, if the base is half as long as the height, you divide it by 2:
[tex]base=\frac{16}{2}=8cm[/tex]
-Then, you substitute it:
[tex]A=16[/tex] · [tex]8[/tex]
-Result:
[tex]128cm^2[/tex]
A bag contains 52 balls lettered from a to z and A to Z (i.e. uppercase or lowercase letters). One ball is withdrawn. What is the probability that the ball will have a letter that is lower case or earlier in the alphabet than d (or D)?
the probability that the ball will have a letter that is lower case or earlier in the alphabet than d (or D) is 0.557
Step-by-step explanation:
Here we have ,A bag contains 52 balls lettered from a to z and A to Z (i.e. uppercase or lowercase letters). One ball is withdrawn. We need to find What is the probability that the ball will have a letter that is lower case or earlier in the alphabet than d (or D)? Let's find out:
There are 26 lowercase letters and 26 uppercase letters ! According to question we need to choose a ball which is either a lowercase ( i.e. from 26 letters ) or earlier in the alphabet than d ( or D ) which is A or B or , C .
Probability = (Favorable outcome)/(Total outcome)
Favorable outcome = 26+3=29
Total Outcome = 52
So ,
⇒ [tex]Probability = \frac{29}{52}[/tex]
⇒ [tex]Probability = 0.557[/tex]
Therefore , the probability that the ball will have a letter that is lower case or earlier in the alphabet than d (or D) is 0.557
Final answer:
To calculate the probability of drawing a ball that is lower case or earlier in the alphabet than 'd', we count the number of qualifying balls (29) and divide by the total number (52), resulting in a probability of 29/52.
Explanation:
The student's question is about calculating the probability of drawing a ball from a bag that either contains a lower case letter or a letter that comes earlier in the alphabet than the letter 'd'. Given that the bag contains 52 balls, with each letter of the alphabet represented in both upper and lower case, we can calculate the probability by counting the number of balls that satisfy the condition and dividing by the total number of balls.
There are 3 letters in the alphabet before 'd' (‘a’, ‘b’, and ‘c’) and each comes in two forms (upper and lower case), so there are 3 * 2 = 6 balls that meet the 'earlier in the alphabet than d' criterion. Since there are 26 letters in the alphabet and each has a lower case form, there are 26 balls that are lower case.
To avoid double-counting the lower case balls ‘a’, ‘b’, and ‘c’, we subtract those 3 balls from the 26 lower case balls, resulting in 23. Adding these 23 to the 6 balls already counted, we have a total of 29 balls that satisfy either condition. The probability is therefore 29/52.

What is the only unknown (variable) needed to find the volume of a sphere?
Sphere
The radius of the sphere is the only unknown variable need to find the volume of a sphere.
Step-by-step explanation:
Sphere is a geometrical three dimensional round figure with every point on its surface equidistant from its center. It is a three dimensional representation of a circle. A line which connects from the center to the surface is called radius of the sphere.The diameter of the sphere is the longest straight line which passes through the center of the sphere.
The volume of sphere is given by:
Volume of sphere(V) = [tex]\frac{4}{3}\pi r^{3} \\[/tex]
where V is the volume of the sphere
r is the radius of the sphere
[tex]\pi = \frac{22}{7}[/tex] = 3.14
Hence the only unknown variable to find the volume of a sphere is the radius.
Let f= {(-5,1).( - 4,0).(0,6)}
Find f(0)
f(0)=
Given:
It is given that the coordinates of the function are [tex]f=\{(-5,1),(-4,0),(0,6)\}[/tex]
We need to determine the value of f(0)
Value of f(0):
The value of f(0) is the value of the function when the input is 0.
We need to determine the value of f(0) when the input is x = 0
Thus, from the coordinates of the function [tex]f=\{(-5,1),(-4,0),(0,6)\}[/tex], it is obvious that the input value of the function is x = 0 , then the value of the function f(0) = 6.
Thus, when the input value x = 0, the output is f(0) = 6.
Therefore, the value of f(0) = 6.

You have learned some new ways in this module to prove that triangles are similar Please describe some of these new postulates and include a diagram on the whiteboard to help explain how they are applied.
Answer:
TA = 6 units
GT = 10 units
Step-by-step explanation:
Angle G is common to both triangles, so that's a congruent angle.
Since RT is parallel to EA,
Angle R = Angle E
And
Angle T = Angle A
When two triangles have the same distribution of angles, they are similar (by AAA).
Therefore GRT and GEA are similar
GE/GR = GA/GT
8/5 = 16/(16-x)
16-x = 16 × 5/8
16 - x = 10
x = 16 - 10
x = 6
GT = 16 - x = 16 - 6 = 10
