8y-2d=0 5y+4d=26 1/4
Answer:
y = 1
d = 4
Step-by-step explanation:
8y - 2d = 0 ---------------(I)
5y + 4d = 26 1/4
5y + 4d = 105/4 ------------------(II)
(I)*2 16y - 4d = 0
(II) 5y + 4d = 105/4 {add (I) &(II)}
21y = 105/4
[tex]y = \frac{105}{5*21}\\\\y=\frac{105}{105}\\\\y = 1[/tex]
Substitute y =1 in equation (I)
8*1 - 2d = 0
8 - 2d = 0
-2d = -8
d = -8/-2
d = 4
Answer:
(y, d) = (1.25, 5)
Step-by-step explanation:
We can add twice the first equation to the second.
2(8y -2d) +(5y +4d) = 2(0) +26 1/4
21y = 26 1/4
y = (105/4)/21 = 105/84 = 5/4
8(5/4) -2d = 0
5 = d . . . . . . . . . . add 2d, divide by 2
The solution to this system of equations is ...
y = 5/4, d = 5

How would you define a pair of parallel lines?
Answer:
We say that two lines (on the same plane) are parallel to each other if they never intersect each other, ragardless of how far they are extended on either side. Pictorially, parallel lines run along each other like the tracks of a train.

Answer:
B.
Step-by-step explanation:
The ratio of the lengths of the sides of a 30-60-90 triangle is
1 : sqrt(3) : 2
From the 1 and 2, we see that the hypotenuse must be twice the length of the short leg.
From the 1 and sqrt(3) we see that the long leg is sqrt(3) times the length of the short leg.
Now we check for these two ratios in each choice.
A.
1 is twice 1/2. Check
sqrt(3)/2 is sqrt(3) times 2. Check
B.
10 is twice 5, not twice 5/2. This does not check.
C.
2sqrt(2) is twice sqrt(2). Check
sqrt(6) is 2sqrt(2) time sqrt(3). Check
D.
6 is twice 3. Check
3sqrt(3) is sqrt(3) times 3. Check
Answer: B.
Answer:
B
Step-by-step explanation:
Angle ratio = 30 : 60 : 90
Side ratio = x : x√3 : 2x
[tex]A) x = \frac{1}{2}\\\\ \ x\sqrt{3 } = \frac{1}{2}*\sqrt{3}=\frac{\sqrt{3}}{2} \\\\2x = 2*\frac{1}{2}=1[/tex]
True
[tex]C) x = \sqrt{2} \\\\x\sqrt{3}=\sqrt{2} *\sqrt{3} =\sqrt{2*3}=\sqrt{6}\\\\2x=2\sqrt{2} \\[/tex]
True
[tex]D) \ x = 3\\\\x\sqrt{3}=3\sqrt{3}\\\\2x = 2*3 = 6[/tex]

(b) In a sale the original prices are reduced by 15%.
(i) Calculate the sale price of a book that has an original price of $12.
$
(ii)
Calculate the original price of a jacket that has a sale price of $38.25.
Answer:
(i): $10.20
(ii): $32:51
Step-by-step explanation:
(i) 1. put the percentage of the discount into a decimal: 0.15
2. multiply 0.15 by the sale price to find the amount of the discount: $1.80
3. subtract the discount, $1.80, from the original price, $12: $10.20
(ii) 1. put the percentage of the discount into a decimal: 0.15
2. multiply 0.15 by the sale price to find the amount of the discount: $5.74
3. subtract the discount, $5.74, from the original price, $38.25: $32.51
(i) The sale price of the book of original price $12 is $10.20.
(ii) The original price of the jacket is $38.25.
What is the percentage?The percentage is a calculation method for every 100.
How to calculate the sale price?The original price of a book is $12.
In a sale the original prices are reduced by 15%.
∴ Price reduced = $(12*15%)
=$ 1.80
Hence, the sale price is = $(12-1.80)
=$10.20
What is discounted price?The discounted price is the price a buyer pays after getting a discount of marked price.
How to calculate original price?Here, the sale reduces price by 15%
The discounted price is equivalent to = (100-15)%
=85%
By the condition ,
85% = $38.25
∴100%= $(38.25/85*100)
=$ 45

Phoebe took a survey of her classmates' favorite sport. The results are in the table below:
What is the relative frequency of survey members who prefer tennis?
The choose ( 0.25 )
Relative Frequency = Category Frequency / Total Frequencies
Category Frequency (prefer tennis) = 7
Total Frequencies = 28
Relative Frequency = 7 / 28
Relative Frequency = 0.25
I hope I helped you^_^
The relative relative frequency of survey members who prefer tennis is found to be 0.25.
Relative FrequencyWhat is relative frequency?The ratio of the total number of events that occur in a experiment to the number of times an event occurs is known as relative frequency.
Formula of relative frequency:Relative Frequency = Subgroup frequency/ Total frequency.
Calculation for relative frequency of tennis:Total frequency for the sports is 28.
The frequency for tennis is 7.
The relative frequency of survey members who prefer tennis =
total frequency for tennis/total frequency for all sports
Relative frequency = 7/28
= 0.25

Is 512 is not a perfect square
Answer:
A perfect square is a number that can be expressed as the product of two equal integers.
The only way to accurately calculate if a number is a perfect square is to find the factors. Before we go through the trouble of finding the factors, there is a quick trick you can use to help determine if you need even need to do the extra work.
Try these steps first:
A number that is a perfect square never ends in 2, 3, 7 or 8. If your number ends in any of those numbers, you can stop here because your number is not a perfect square.
Obtain the digital root of the number. The digital root essentially is the sum of all of the digits. If you're lost, don't worry, we'll go over each step in more detail below.
All possible numbers that are a perfect square have a digital root of 1, 4, 7, 9.
Let's try it...
Step 1:
What is the last number of 512? It is this number: 512. The answer is 2. Is 2 in the list of numbers that are never perfect squares (2, 3, 7 or 8)?
Answer: YES, 2 is in the list of numbers that are never perfect squares. The number 512 is NOT a perfect square and we can stop here as there is not need to complete the rest of the steps.
