what is the inequality statement 4/13 6/13
Answer:
4/13 < 6/13
Step-by-step explanation:
I will assume you want to see which one is greater.
We don't need to find common denominators since they already have one which is 13.
We know that 4 < 6 so this means that 4/13 < 6/13

Cary is having a party and can only afford to spend no more than $40 on food. She wants to order at least 3 pizzas which cost $6 a pie, and at least 2 orders of wings that cost $8 per order. Select all the inequalities she would have to graph to determine how many pizzas and wings she could order. Let x stand for the number of pizzas and y stand for the number of wings.
Answer:
y ≥ 2
x ≥ 3
6x + 8y ≤ 40

What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
From the graph, the line is passing through two points (0, 10) and (5, 0)
m=0-10/5-0=-2
From the graph, the x intercept is at 5 on x axis.
Sam spending 5 hours on the internet and no time watching the television.
Hence, Sam spending 5 hours on the internet and no time watching the television.

At which value will the graph of y = cotx have a zero?
Answer:
ℼ/2.
Step-by-step explanation:
y = cot x have zero for value of x = nπ + π/2
What are trigonometric ratio ?In trigonometry, there are six trigonometric ratios, namely, sine, cosine, tangent, secant, cosecant, and cotangent. These ratios are written as sin, cos, tan, sec, cosec(or csc), and cot in short.
Given equation,
y = cot x
It is given that cot x = 0
cot is zero in the first and the third quadrants.
cot π/2 = 0.
In the first quadrant, x = π/2
In the third quadrant, x = π + π/2 as cot 3π/2 = 0
Thus, the principle solutions are: x = π/2, and 3π/2.
Now,
cot x = cot π/2
Therefore, x = nπ + π/2, where n ∈ Z is the general solution.
Hence, for value of x = nπ + π/2, graph of y = cot x have a zero.

N a toy store, the ratio of the number of dolls to the number of teddy bears is . If the store has 240 dolls, how many teddy bears are in the store? Use pencil and paper. Describe the mental math steps you use to solve this problem.
Answer:
There are 80 teddy bears in the store.
Step-by-step explanation:
Let the ratio of the number of dolls to the number of teddy bears is 9:3.
Total no of dolls = 240
We need to find the no of teddy bears in the store.
Let D and T are the no of dolls to the no of teddy bears.
So,
[tex]\dfrac{D}{T}=\dfrac{9}{3}\\\\T=\dfrac{3D}{9}\\\\\text{Put D= 240}\\\\T=\dfrac{3\times 240}{9}\\\\T=80[/tex]
So, there are 80 teddy bears in the store.
Leon packs thirty business envelopes in each of twenty-five boxes and thirty regular envelopes in each of twenty boxes. How many envelopes does he pack?
Answer: 1350 envelopes
Step-by-step explanation:
From the question, Leon packs thirty business envelopes in each of twenty-five boxes. The total business envelopes here will be:
= 30 × 25
= 750
Leon picked thirty regular envelopes in each of twenty boxes. The total regular envelopes will be:
= 30 × 20
= 600
Total envelopes will now be:
= 750 + 600
= 1350 envelopes
Point L is on line segment \overline{KM}
KM
. Given LM=3x+3,LM=3x+3, KM=5x+4,KM=5x+4, and KL=5x+1,KL=5x+1, determine the numerical length of \overline{KM}.
KM
.
Answer:
KM = 4 units
Step-by-step explanation:
Here, we are to determine the numerical length of KM
since point L is on the line segment;
Then;
KM = KL + LM
Thus;
5x + 4 = 5x + 1 + 3x + 3
5x + 4 = 8x + 4
8x - 5x = 4-4
3x = 0
x = 0/3 = 0
From the question;
KM = 5x + 4
Substitute x = 0
Thus we have;
5(0) + 4 = 4
KM = 4 units

Darlene purchases 20,000 worth of stock on her brokers advice and pays her broker a 1.5% broker fee darlene purchases 20,000 worth of stock on your brokers advice and pays her broker a 1.5% broker freeshe sells her stock when it increases to $28,600.02 years later and uses a discount broker who charges $21 per trade compute Darlenes net proceeds after the broker fees are taken out
Answer:
Darlene's net proceeds after the broker fees are taken out is $8,279.
Step-by-step explanation:
From the question, the following can be obtained:
Basic cost of purchase of the stock = $20,000
Broker fee related to purchase = Basic cost of purchase of the stock * 1.5% = $20,000 * 1.5% = 300
Total cost of purchase of the stock = Basic cost of purchase of the stock + Broker fee related to purchase = $20,000 + 300 = $20,300
Selling price = $28,600
Broker fees related sales = 21
The net proceed can therefore be calculated as follows:
Net proceeds = Selling price - Broker fees related sales - Total cost of purchase of the stock = $28,600 - $21 - $20,300 = $8,279
Therefore, Darlene's net proceeds after the broker fees are taken out is $8,279.
