Find the inequality represented by the graph
Answer:
[tex]y<\frac{1}{4}x+3[/tex]
Step-by-step explanation:
we know that
The solution of the inequality in the graph is the shaded area below the dashed line
The slope of the dashed line is positive
The y-intercept of the dashed line is (0,3)
The dashed line pass through the points (0,3) and (4,4)
The slope of the dashed line is
[tex]m=(4-3)/(4-0)=1/4[/tex]
The equation of the dashed line in slope intercept form is
[tex]y=\frac{1}{4}x+3[/tex]
therefore
The inequality represented by the graph is
[tex]y<\frac{1}{4}x+3[/tex]
Solve for z in the problem below:
4/5 = z/20
A.z = 16
B. z = 80
C. z = 13
D. z = 5
Answer:
A
Step-by-step explanation:
Given
[tex]\frac{4}{5}[/tex] = [tex]\frac{z}{20}[/tex]
Multiply both sides by 20 to clear the fractions
16 = z → A
Answer:
A. z = 16
Step-by-step explanation:
Multiply both sides by 20 isolate the variable z.
[tex]\frac{4}{5} *\frac{z}{20}[/tex]
[tex]\frac{4}{5} *20 = \frac{z}{20} *20[/tex]
[tex]z = \frac{4}{5} *20[/tex]
Multiplying [tex]\frac{4}{5}[/tex] by 20 will give us 16.
[tex]\frac{4}{5} *\frac{20}{1} = \frac{80}{5}[/tex][tex]= 16[/tex]
Therefore, z is equal to 16.
Damian has a spinner. He spun the arrow 60 times and it landed on green 12 times.
Based on the data, how many times would the arrow land on green if Damian only spun it 10 times?
Answer:
it would be 2
Step-by-step explanation:
what you do to find the probability is to divide so you divide 60 from 12 which automatically = 5 so then you divide 10 from 5 which gives you 2
The Correct Answer is 2 times
On spinning 60 times domain landed arrow 12 times.
On 1 time spinning, he will land an arrow [tex]\frac{60}{12}[/tex]=5
∴ number of times arrow landed on green = [tex]\frac{10}{5}[/tex]=2
How do you calculate probability?Divide the number of events by the number of possible outcomes. This will give us the probability of a single event occurring. In the case of rolling a 3 on a die, the number of events is 1 (there's only a single 3 on each die), and the number of outcomes is 6.

Rosalie is training for a marathon. She jogs for 30 minutes at a rate of 5 miles per hour, then she decreases her speed over a period of time and walks for 60 minutes at a rate of 3 miles per hour.
What is the range of this relation?
A.
0 ≤ y ≤ 5
B.
y ≤ 5
C.
y ≥ 0
D.
3 ≤ y ≤ 5
Answer:
3 ≤ y ≤ 5
Step-by-step explanation:
Rosalie is training for a marathon. She jogs for 30 minutes at a rate of 5 miles per hour, then she decreases her speed over a period of time and walks for 60 minutes at a rate of 3 miles per hour.
Therefore, the speed (y) of Rosalie ranges from 5 mph to 3 mph including the values.
So, the range of this relation is 3 ≤ y ≤ 5. (Answer)
We can see here that the range of this relation is: D. 3 ≤ y ≤ 5
How we arrived at the solution?To determine the range of this relation, let's first calculate the distances Rosalie covers during each phase of her training:
Jogging phase:
Time = 30 minutes = 0.5 hours
Speed = 5 miles per hour
Distance = Speed × Time = 5 × 0.5 = 2.5 miles
Walking phase:
Time = 60 minutes = 1 hour
Speed = 3 miles per hour
Distance = Speed × Time = 3 × 1 = 3 miles
Now, let's consider the range of distances Rosalie covered during her training:
The minimum distance she covered is 2.5 miles (jogging phase), and the maximum distance is 2.5 + 3 = 5.5 miles (jogging + walking phases).
The given options are:
A. 0 ≤ y ≤ 5
B. y ≤ 5
C. y ≥ 0
D. 3 ≤ y ≤ 5
Since the minimum distance covered is 2.5 miles and the maximum distance covered is 5.5 miles, the correct option that represents the range of this relation is:
D. 3 ≤ y ≤ 5

Step-by-step explanation:
Tom bought his fiancée Marie a 3800 diamond engagement ring Marie discovers that the value of the ring appreciates 4% each year what is the value of the ring after 4 years
Value of ring after four years with appreciation of 4 % each year is 4445.46
Solution:Given that
Tom bought his fiancée Marie a 3800 diamond engagement ring
Marie discovers that the value of the ring appreciates 4% each year
Need to determine value of ring after four years
Initial value of the ring = 3800
Appreciation of 4% in value means 4% increase
After 1 years , value increases by 4% which means
Value after 1 year = Initial value of the ring + 4% of Initial value of the ring
[tex]\begin{array}{l}{=3800+4 \% \text { of } 3800} \\\\ {=3800+\frac{4}{100} \times 3800=3952}\end{array}[/tex]
After 2 years, value increases by 4% of Value after 1 year which means
Value after 2 years = Value after 1 year + 4% of Value after 1 year
[tex]\begin{array}{l}{=3952+4 \% \text { of } 3952} \\\\ {=3952+\frac{4}{100} \times 3952=4110.08}\end{array}[/tex]
After 3 years, value increases by 4% of Value after 2 years which means
Value after 3 years = Value after 2 years + 4% of Value after 2 years
[tex]\begin{array}{l}{=4110.08+4 \% \text { of } 410.08} \\\\ {=4110.08+\frac{4}{100} \times 4110.08=4274.4832}\end{array}[/tex]
After 4 years , value increases by 4% of Value after 1 year which means
Value after 4 years = Value after 3 years + 4% of Value after 3 years
[tex]\begin{array}{l}{=4274.4832+4 \% \text { of } 4274.4832} \\\\ {=4274.4832+\frac{4}{100} \times 4274.4832=4,445.46}\end{array}[/tex]
Value of ring after four years with appreciation of 4 % each year is 4445.46
To calculate the future value of a ring appreciating at 4% each year for 4 years, compound interest formula is used. The ring's value after 4 years is approximately $4,445.46.
Explanation:The question refers to the calculation of the future value of an investment, which is a common problem in mathematics dealing with compound interest. Tom bought an engagement ring for $3,800, and its value appreciates at a rate of 4% each year. To find the value of the ring after 4 years, we use the formula for compound interest:
Future Value = Present Value x (1 + Rate of Interest)Number of Years
Step-By-Step Calculation
After applying the compound interest formula, the value of the ring after 4 years would be approximately $4,445.46.

What is -2-(-3)? Show your work.
When subtracting with a negative number anywhere in the expression you will do something called "Same-Add-Opposite."
This means that you will keep the first number in the expression (in this case that is -2) the same:
-2 - (-3)
Then turn the subtraction sign into an addition sign.
-2 + (-3)
Finally you will take the "opposite" sign of the second number (in this case you will take the opposite of -3). When I say "opposite sign" I mean that if this number is positive it will become negative. If it was negative it will become positive.
-2 + 3
Now you must solve. When adding a positive number with a negative number you will act as if you are subtracting the two numbers, then the answer will take the sign of the largest number (disregarding the signs).
In this case the largest number is 3 (disregarding the signs) and its sign is positive. Your answer will have a negative sign.
-2 + 3

-2 - (-3) = 1

The perimeter of a rectangle is twice the sum
of its length and its width. The perimeter is
40 meters and its length is 2 meters more
than twice its width.
The question is incomplete, here is the complete question:
The perimeter of a rectangle is twice the sum of its length and its width, the perimeter is 40 meters and the length is 2 meters more than twice its width. What is the length?
The length of the rectangle is 14 meters
Step-by-step explanation:
The formula of the perimeter of a rectangle is P = 2(L + W), where
L is its lengthW is its widthAssume that the width of the rectangle is x meters
∵ The width of the rectangle = x meters
∵ Its length is 2 meters more than twice its width
- Multiply x by 2 and then add to the product 2
∴ The length of the rectangle = 2 x + 2 meters
∵ The formula of the perimeter is P = 2(L + W)
- Substitute L by 2 x + 2 and W by x
∴ P = 2(2 x + 2 + x)
- Add like terms in the bracket
∴ P = 2(3 x + 2)
- Simplify the right hand side
∴ P = 6 x + 4
∵ The perimeter of the rectangle = 40 meters
- Equate P by 40
∴ 6 x + 4 = 40
- Subtract 4 from both sides
∴ 6 x = 36
- Divide both sides by 6
∴ x = 6
∴ The width of the rectangle is 6 meters
∵ The length = 2 x + 2
- Substitute x by 6
∴ The length = 2(6) + 2 = 12 + 2 = 14 meters
The length of the rectangle is 14 meters

[tex]n(B) = \{3,4,5,6\}\\n(B) = 4[/tex]
To find:
the probability of complement of B that is
p(~B) = ?
Solution"
First we need to solve probability for number getting greater than two
[tex]p(B) = \frac{n(B)}{n(S)}[/tex]
Now substituting the values we get
[tex]p(B) = \frac{4}{6}[/tex]
[tex]p(B) = \frac{2}{3}[/tex]
but we need complement of B so
[tex]p(\textrm{complement of B)} = 1 - p(B)\\p(\~B) = 1 - p(B)\\p(\~B) = 1 - \frac{2}{3}\\ =\frac{1}{3} \\[/tex]
P(complement of rolling a number greater than two) = [tex]\frac{1}{3}[/tex]
Amelia sells exquisite, hand-crafted jewelry. She makes a total of 12%
commission off of her sales. How much commission will Amelia make if
she sells $22,540 worth of jewelry?
Answer:
$2704.80
Step-by-step explanation:
If she makes 12% commission off of it, she makes [tex]\frac{22540}{1} *\frac{12}{100}=$2704.80\\[/tex]
Final answer:
To calculate Amelia's commission, convert the 12% commission rate to a decimal (0.12) and multiply it by her sales of $22,540. Amelia will earn a commission of $2,704.80.
Explanation:
The question asks us to calculate how much commission Amelia makes on her sales of hand-crafted jewelry, given a commission rate of 12% and sales amounting to $22,540. To find the commission, we need to multiply the total sales by the commission rate expressed as a decimal.
Steps to Calculate Commission
Convert the commission rate from a percentage to a decimal by dividing by 100: 12% / 100 = 0.12.
Multiply the sales amount by the decimal commission rate: $22,540 × 0.12 = $2,704.80.
Amelia's commission for selling $22,540 worth of jewelry is $2,704.80.
Jasmine has 84 flowers available to make bouquets for the farmer's market. To make the bouquets more appealing to the
she would like to have an odd number of flowers in each. She wants to use all of the available flowers. To meet lasmines
requirements, how many flowers could she put in each bouquet?
HELP PLZZ
Answer:
Jasmine could have 84 bouquets with 1 flower in each,28 bouquets with 3 flower in each,12 bouquets with 7 flower in each or 4 bouquets with 21 flower in each.Step-by-step explanation:
The total number of flowers that jasmine has to make bouquets is 84.
We need to note that she want to use all the flowers.
Now let us write down all factors of 84.
84= 1 * 84 ....(1)
= 2 * 42 ....(2)
= 3 * 28 ....(3)
= 4 * 21 ....(4)
= 6 * 14 .....(5)
= 7 * 12 ....(6)
Now all we need is odd number of flowers in each bouquet,i.e,
All the numbers written in the right hand side of the above 1 to 6
numbered equations are factors of 84.
Since Jasmine wanted no flowers to be wasted so we can assume that number of flowers in each bouquet must be an odd factor of 84.
Therefore, odd factors of 84 are 1,3,7,21.
So Jasmine could have 84 bouquets with 1 flower in each,28 bouquets with 3 flower in each,12 bouquets with 7 flower in each or 4 bouquets with 21 flower in each.

Graph each inequality given on the same xy coordinate system. You should get what you see in the attached image below. The red shaded region represents all points that make every inequality mentioned to be a true statement. Points A, B, C are vertex points of the boundary region.
A = (2,6)
B = (5,3)
C = (2,3)
For each point A,B,C, plug in the (x,y) coordinates into the C(x,y) function given
------
For point A, (x,y) = (2,6) so x = 2 and y = 6
C(x,y) = (1/2)*x - y
C(2, 6) = (1/2)*2 - 6
C(2, 6) = -5 we'll use this value later
-----
Repeat for point B = (5,3)
C(x,y) = (1/2)*x - y
C(5,3) = (1/2)*5 - 3
C(5,3) = -0.5 we'll use this value later
----
Repeat for point C = (2,3)
C(x,y) = (1/2)*x - y
C(2,3) = (1/2)*2 - 3
C(2,3) = -2 we'll use this value later
-----
In the previous three sections above, we got the following outputs: -5, -0.5, -2
We see that -5 is the smallest and -0.5 is the largest
Therefore, -5 is the min and -0.5 is the max

m∠JKL = 87°
m∠KJL = 58°
m∠KLJ = 35°
m∠KLM = 145°
Step-by-step explanation:
The exterior angle theorem says that the sum of two interior angles is equal to the exterior angle
In the given triangle, the interior angles are:
m∠K = (7x-32)°
m∠J = (5x-27)°
The interior angle is:
m∠L = (9x-8)°
So writing mathematically
m∠J+m∠K = m∠L
[tex]7x-32+5x-27 = 9x-8\\12x -59 = 9x - 8\\12x-9x = 59-8\\3x = 51[/tex]
Dividing both sides by 3
[tex]\frac{3x}{3} =\frac{51}{3}\\x = 17[/tex]
Now m∠JKL
= [tex]7x-32\\=7(17) - 32\\=119-32\\=87[/tex]
m∠KJL
[tex]= 5x-27\\=5(17)-27\\=85-27\\=58[/tex]
m∠KLJ
[tex]=188-9x\\=188-153\\=35[/tex]
m∠KLM
[tex]=9x-8\\=9(17) -8\\=153-8\\=145[/tex]
Hence,
x = 17
m∠JKL = 87°
m∠KJL = 58°
m∠KLJ = 35°
m∠KLM = 145°
