Answer:
y= 5/8x
Step-by-step explanation:
When it says y is it typically means y=.
When it says 5/8 of a number or of a variable it means that number times that variable.

Diego is thinking of two positive numbers. He says, "If we triple the first number and double the second number, the sum is 34." a. Write an equation that represents this clue. Then, find two possible pairs of numbers Diego could be thinking of. b. Diego then says, "If we take half of the first number and double the second, the sum is 14." Write an equation that could represent this description. c. What is Diego's two numbers? Explain or show how you know. A coordinate plane is given here, in case helpful.
Answer:
x = 8
y = 5
Step-by-step explanation:
Let
x and y = the two positive numbers
a. 3x + 2y = 34 (1)
b. 1/2x + 2y = 14 (2)
Solve the simultaneous equation
3x + 2y = 34 (1)
1/2x + 2y = 14 (2)
Subtract (2) from (1)
3x - 1/2x = 34 - 14
6x-x/2 = 20
5/2x = 20
x = 20 ÷ 5/2
= 20 × 2/5
= 40/5
= 8
x = 8
Substitute x = 8 into (1)
3x + 2y = 34 (1)
3(8) + 2y = 34
24 + 2y = 34
2y = 34 - 24
2y = 10
y = 10 / 2
= 5
y = 5

Student Council is sponsoring the next school dance. They plan to order 2 cheese pizzas for every 3 pepperoni pizzas they order. How many total pizzas will they order if they plan to order 36 pepperoni pizzas for the dance?
Answer: 60 pizzas
Step-by-step explanation:
From the question, we are informed that the student council plan to order 2 cheese pizzas for every 3 pepperoni pizzas they order.
Since 36 pepperoni pizzas are ordered for the dance, the number of cheese pizzas ordered will be:
= 36 × 2/3
= 24 cheese pizzas
The total pizza ordered will now be:
= Cheese pizzas + Pepperoni pizzas
= 24 + 36
= 60 pizzas
Answer:
60

A store charges 5.5 % sales tax on all items. If an item costs d dollars before tax, which expression represents the total cost of the item, in dollars and cents, after tax?
Answer: d + 0.055d or 1.055d
Step-by-step explanation:
Cost of item = d
Sales tax percent = 5.5%
Total cost = Cost of item + Sales tax
= d + (5.5% × d)
= d + (5.5/100 × d)
= d + (0.055 × d)
= d + 0.055d
= 1.055d
Therefore, the expression that represents the total cost of the item, in dollars and cents, after tax will be:
d + 0.055d or 1.055d.
Mai uses Triangle A and says the slope of this line is `\frac{6}{4}.` Elena uses Triangle B and says no, the slope of this line is `1.5.` Do you agree with either of them? Explain.
Answer:
I agree with both of them because they are both correct
Step-by-step explanation:
See attachment for complete question;
Slope (m) is calculated using the following formula:
[tex]m = \frac{Rise}{Run}[/tex]
Where
[tex]Rise = Vertical\ Distance[/tex]
[tex]Run = Horizontal\ Distance[/tex]
From the attachment, we have the following:
Triangle A
[tex]Rise = 6\ units[/tex]
[tex]Run = 4\ units[/tex]
So:
[tex]m = \frac{Rise}{Run}[/tex]
[tex]m = \frac{6}{4}[/tex]
In this case, Mai is correct:
Triangle B
[tex]Rise = 1.5\ units[/tex]
[tex]Run = 1\ units[/tex]
So:
[tex]m = \frac{Rise}{Run}[/tex]
[tex]m = \frac{1.5}{1}[/tex]
[tex]m = 1.5[/tex]
In this case, Elena is also correct:

So far this month Aaron calculated that he will earn $40 in commission for his $500 in product sales. If Aaron would like for his commission to be $320, how much will his product sales need to be?
Answer:
$4000 in product sales
Step-by-step explanation:
[tex]\frac{40}{500} =\frac{320}{x} = 4000[/tex]
Answer:
$4000
Step-by-step explanation:
i) Calculate if $1 = ? commission
500/40 = $12.5
$1 = $12.5 commission
ii) If the commission $320,
320×12.5=4000
His product sales need to be $4000
Bella is working on the world record for longest beaded necklace. She has 10,000 glass beads that have a diameter of 0.4 cm. If she strings these beads end to end, how long will her necklace be.
Answer:
The necklace will be 4,000 cm long
Step-by-step explanation:
Here we want to calculate the length of the necklace
Mathematically, that would just be the product of the beads and the diameter of each bead
Hence, we have
10,000 * 0.4 = 4,000 cm
The birth weights of newborn babies in the United States follow a normal distribution with a mean of 3.4 kg and a standard deviation of 0.6 kg. Researchers interested in studying how children gain weight decide to take random samples of 100 newborn babies and calculate the sample mean birth weight for each sample. Calculate the mean and standard deviation of the sampling distribution
Answer:
3.4 kg
0.06 kg
Step-by-step explanation:
Given that:
Birthweight follows a normal distribution :
Mean weighf (m) = 3.4 kg
Standard deviation (σ) = 0.6 kg
Sample size (n) = 100 new born babies
calculate the sample mean birth weight for each sample. Calculate the mean and standard deviation of the sampling distribution
The sample mean birth weight = population mean birth weight for a normal distribution according to the central Limit theorem.
Hence, sample mean birth weight = 3.4kg
Standard deviation of sampling distribution = standard error = σ/√n
0.6 / √100
= 0.6 / 10
= 0.06 kg
Using the Central Limit Theorem, it is found that:
The mean is of 3.4 kg.The standard deviation is of 0.06 kg.Central Limit Theorem The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex]. For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.In this problem:
Mean of 3.4 kg, hence [tex]\mu = 3.4[/tex].Standard deviation of 0.6 kg, hence [tex]\sigma = 0.6[/tex].Samples of 100, hence [tex]n = 100, s = \frac{0.6}{\sqrt{100}} = 0.06[/tex]Hence, the mean of the sampling distribution is of 3.4 kg and the standard deviation is of 0.06 kg.

Is there enough information to prove the two triangles congruent? If yes, write the congruence statement and name the postulate you would use. If no, write not possible and tell what other information you would need.
Answer:
Step-by-step explanation:
yes, both are congruent by SAS Postulate
<SQP=<SQR (common in both (construction))
QS=QS (common side in both angle)
QP=QR ( as given)
hence, QPS=QRS
by SAS postulate
By SAS postulate Δ QSP ≅ Δ QSR.
What is Congruence Rule?The triangles are said to be congruent when two angles and a non-included side of one triangle match the corresponding angles and sides of another triangle.
When two angles and the included side of one triangle are equal to two angles and the included side of another triangle, two triangles are said to be congruent.
Given:
In Δ QSP and Δ QSR
<SQP=<SQR (common in both (construction))
QS=QS (common side in both angle)
QP=QR ( as given)
So, by SAS postulate Δ QSP ≅ Δ QSR.

Terry increased the size of his rectangular garden this summer. He increased to length by 50% and the width by 20% by what percentage has his garden changed with these changes?
Given :
Terry increased the size of his rectangular garden this summer. He increased to length by 50% and the width by 20%.
To Find :
By what percentage has his garden changed with these changes.
Solution :
Let, initial length and breadth is x and y.
So, initial area = xy .
Size after increasing them :
y' = y + 0.50y
y' = 1.5y
x' = x + 0.2x
x' = 1.2x
Final area = (1.5y)(1.2x) = 1.8xy
So, percentage increase is :
[tex]= \dfrac{new-original}{original }\times 100\%\\\\= \dfrac{1.8xy -xy}{xy }\times 100\\\\=80 \%[/tex]
Therefore, percentage increase in are is 80%.
Hence, this is the required solution.
