Which equation represents the lower unit rate of these two relationships?
A. y=2/9x
B. y=1/4x
C. y=1/5x
D. y=2/11
Answer:
the answer is d y=2
_ x
11
Step-by-step explanation:
I got it right on the test
2/11 is lower than 2/9, therefore the equation that will represent a lower unit rate (k) of both relationships given is: D. y=2/11
A proportional relationship between variable y and x can be expressed as:
y = kx
Where,k is the unit rate/constant of proportionality.
Therefore,k = y/x
Thus, find the equation for the table and the graph respectively in order to determine which equation represents the lower unit rate.
Equation for the table using a pair of coordinates, say (11, 2):
Find, unit rate (k) by substituting x = 11, and y = 2 into k = y/x
Thus:k = 2/11
Plug in the value of k = 2/11 into y = kx
The equation for the table is:
y = 2/11x
Equation for the graph using a point on the line, say (9, 2):
Find, unit rate (k) by substituting x = 9, and y = 2 into k = y/x
Thus:k = 2/9
Plug in the value of k = 2/9 into y = kx
The equation for the table is:y = 2/9x
In conclusion, 2/11 is lower than 2/9, therefore the equation that will represent a lower unit rate (k) of both relationships given is: D. y=2/11

c. 9/5
d. 515
b
Ο Ο Ο Ο
d
Answer:
The simplest radical form is [tex]9\sqrt{5}[/tex] ⇒ (c)
Step-by-step explanation:
To simplify any square root;
Factorize the number under the root using prime numbersTake out the root any number repeated twice as one numberExamples:
1. Simplify [tex]\sqrt{8}[/tex]
factorize 8 using prime numbers
8 = 2 × 2 × 2, then [tex]\sqrt{8}=\sqrt{(2)(2)(2)}[/tex]
Take two of 2 out the root, then [tex]\sqrt{8}=2\sqrt{2}[/tex]
2. Simplify [tex]\sqrt{18}[/tex]
factorize 18 using prime numbers
18 = 2 × 3 × 3, then [tex]\sqrt{18}=\sqrt{(2)(3)(3)}[/tex]
Take the two 3 out the root, then [tex]\sqrt{18}=3\sqrt{2}[/tex]
Let us simplify [tex]3\sqrt{45}[/tex]
∵ 45 = 3 × 3 × 5
∴ [tex]3\sqrt{45}=3\sqrt{(3)(3)(5)}[/tex]
→ Take the two 3 out by one 3
∴ [tex]3\sqrt{45}=3(3)\sqrt{5}[/tex]
→ Multiply the numbers out the root
∴ [tex]3\sqrt{45}=9\sqrt{5}[/tex]
∴ The simplest radical form is [tex]9\sqrt{5}[/tex]

Seema bought a new pair of jeans that were on sale. The original price of the jeans was $56. The store had marked them down by 25 percent, and Seema had a 20 percent off coupon as well. Original price: $56 25% 25% 25% 25% $42 20% 20% 20% 20% 20% $8.40 $8.40 $8.40 $8.40 What was the price of the jeans before tax?
Given :
The original price of the jeans was $56.
The store had marked them down by 25 percent and Seema had a 20 percent off coupon as well.
To Find :
The price of the jeans before tax.
Solution :
Discount offered by store :
Discount = 0.25×56 = $14 .
Selling price = $( 56 - 14 ) = $42 .
Discount offered through coupon on selling price :
Discount = 0.20×42 = $8.4 .
Final price = $( 42 - 8.4 ) = 4= $33.6 .
Therefore, the price of the jeans before tax is $33.6 .
Hence, this is the required solution.

33.60

(62 points) Jim makes $5 an hour at the surf shop. His boss gives him a one time bonus of $50. Sarah makes $8 an hour at the clothes store. Her boss gives her a one time bonus of $14. After how many hours will their paychecks be the same?
Answer:
12 hours
Step-by-step explanation:
So we know that Jim makes $5 an hour and was given a one time bonus of $50. Using the information given, we can make the expression:
5h + 50
to represent how much Jim makes in h hours.
Now we also know that Sarah makes $8 an hour and was given a one time bonus of $14. Using this information, we can make the expression:
8h + 14
to represent how much Sarah makes in h hours.
Now to find how many hours it will take for their paychecks to be the same, we have to set the two expressions equal to each other and solve for h:
8h + 14 = 5h + 50
Now solve for h. Subtract 5h from both sides.
3h + 14 = 50
Subtract 14 from both sides.
3h = 36
Divide both sides by 3.
h = 12
So it will take 12 hours for their paychecks to be the same.

Write an equation in point-slope form of the line that passes through the given point and with the given slope m.
(-8,7), m = 4
Step-by-step explanation:
y-y1=m(x-x1)
y-7=4(x+8)
y-7=4x+32
4x-y=-39
Answer:
y = 4x + 39
Step-by-step explanation:
The line passes through point (-8,7) and;Has a slope (m) = 4Let's take another point (x,y) on the line.
Slope (m) = change in y ÷ change in x
∴ m = [tex]\frac{y - 7}{x - -8} = 4[/tex]
y = 4x + 32 + 7
y = 4x + 39

5. Average (missing value). The temperature at the top of Mt. Hood in Oregon was recorded for 5 straight days. For the first four days, the temperatures were 32°, 30°, 22°, and 10°, but a researcher lost the value of day #5. If the average temperature over the 5 days was 19.8°F, what is the missing temperature of day #5?
Answer:
5°F
Step-by-step explanation:
Given that the average is obtained from;
Average = sum of scores / number of scores
Average temperature = 19.8°F
Let the temperature of the fifth day be x
Hence;
19.8 = 32 + 30 + 22 + 10 + x/5
19.8 = 94 + x/5
x= (5×19.8) -94
x= 5°F

A circular pool has an area of approximately 154 square feet. To the nearest foot, how much fencing is needed to completely surround the pool?
Given parameters:
Area of pool = 154ft²
Unknown:
The circumference or perimeter of the pool = ?
Solution:
The amount of fencing needed for the pool is the same as the circumference of the pool or the perimeter of the pool.
To solve this problem, we need to find the radius from the given area.
Area of a circle = π r²
154 = π r²
r² = [tex]\frac{154}{3.142}[/tex] = 49
r = 7ft
Now the circumference of a circle = 2 π r
= 2 x π x 7
= 44ft
The circumference of the circle is 44ft
