The cost, y y , for x x pounds of nails can be represented by the equation y=3.20x y = 3.20 x . What is the constant of proportionality of the equation?
Answer:
3.20
Step-by-step explanation:
If y is proportional to x as represented as;
y = 3.20x
This means that the relationship between y and x is a direct proportionality
y = kx
k is the constant of proportionality
Comparing with the given equation we will see that k = 3.20
Hence the constant of proportionality is 3.20
PLEASE HELP!!! ILL GIVE BRAINLIEST!
Answer: Last Option (Red In Colour)
Reason: Since Point Slope Form is y -y1 = m(x-x1), We just plug in the numbers. Four will go into the x1 spot, and Zero will go into the y1 spot, and 1/2 in the m spot since it's the slope. So, after plugging everything in, the equation is y - 0 = 1/2 ( x- 4)
I hope this helps, and Happy Holidays! :)
Ida needs to hire a singer for her wedding. Singer A is offering his services for an initial $95 in addition to $12.95 per hour. Singer B is offering her services for an initial $99 in addition to $11.85 per hour. When will the two singers charge the same amount of money? If necessary, round your answer to the nearest tenth.
Answer:
The answer is 3.6
Step-by-step explanation:
Step one:
Singer A is offering his services for an initial $95 in addition to $12.95 per hour
let the number of hours be x and the total charge be y
the expression for the total for singer A is
y=12.95x+95----------2
Singer B is offering her services for an initial $99 in addition to $11.85 per hour
let the number of hours be x and the total charge be y
the expression for the total for singer A is
y=11.85x+99----------2
Step two:
Equating 1 and 2 we have
12.95x+95=11.85x+99
collect liker terms
12.95x-11.85x=99-95
1.1x=4
divide both sides by 1.1
x= 4/1.1
x=3.63
to the nearest tenth it is 3.6

A supermarket has bags of red grapes for 22.96 for 7 bags
They also had bags of green grapes priced 9.60 for 3 bags
Which type was most expensive?
Answer:
The bag of red grapes costs more.
Step-by-step explanation:
We can do proportions.
A supermarket has bags of red grapes for 22.96 for 7 bags:
[tex] \frac{22.96 \: dollars}{7 \: bags} = \frac{x}{1 \: bag} \\ \frac{7x}{7 } = \frac{22.96}{7} \\ x = 3.28[/tex]
For one bag of red grapes, its costs $3.28.
They also had bags of green grapes priced 9.60 for 3 bags:
[tex] \frac{9.60 \: dollars}{3 \: bags} = \frac{x}{1} \\ \frac{3x}{3} = \frac{9.60}{3} \\ x = 3.2 \: \: \: - > 3.20[/tex]
One bag of green grapes costs $3.20.
The bag of red grapes costs more.

mLABE =
Answer:
m∠ABE = 62°
Step-by-step explanation:
Since, the given quadrilateral is a kite, diagonals will intersect at 90°.
Therefore, m∠AEB = m∠CEB = 90°
m∠BAE = 28° [Given]
m∠BCE = 58° [Given]
From ΔABE,
m∠BAE + m∠BEA + m∠ABE = 180°
28° + 90° + m∠ABE = 180°
m∠ABE = 180° - 118°
= 62°
Therefore, measure of angle ABE = 62°.

In a survey of 3300 people who owned a certain type of car, 1320 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer: The percent of the people surveyed were satisfied with the car = 40% .
Step-by-step explanation:
Given: Total number of people surveyed = 3300
Number of people said that they would buy that type of car again = 1320
i.e. Number of people were satisfied with the car = 1320
The percent of the people surveyed were satisfied with the car =
[tex]=\dfrac{1320}{3300}\times100\\\\=\dfrac{12}{30}\times100\\\\=\dfrac{4}{10}\times100\\\\=0.4\times100=40\%[/tex]
Hence, the percent of the people surveyed were satisfied with the car = 40% .
pls help !!!!!! i need the answer for this pleasee <33
Answer:
slope- intercept form is
y=mx+b
m= slope
b= y-int
looking at the chart we can see that the graph goes up 11 and right 6
so we now have
y= 11/6x+b
we could also do
m=(y2-y1)/(x2-x1) using our points
m=(21-10)/(-3-(-9)
m=11/6
then we can use an x value and its corresponding y value from the equation to find b
I will use the points -9,10
10= 11/6(-9)+b
10=-16.5+b
+16.5 +16.5
26.5=b
so your full equation is:
y=11/6x + 26.5

Now, we see line NO. The angles that include line NO would be angle MNO and angle MON.
For question number 4:
We can see that there is a tick mark on side AC and side DF, meaning those two sides are congruent.
We then see that angle A is congruent to angle D, since there is that little curve mark, showing they are congruent.
Last, we see that they both triangles have 90 degree angles, shown with the square on the corner of the triangle..
Using the AAS Postulate (Angle Angle Side), we can say that triangle ABC is congruent to triangle DEF.

Step-by-step explanation:
(a) Since values 5 or up go up and 4.9 and under go down, Naomi could have gone 4555 to 4564.9, as 4555 rounds up to 4560 (and is the largest number that does so) and vice versa for 4564.9
Similarly, Peta could have went from 4550 to 4649.9.
(b)
Peta could have walked 4550 and Naomi 4564.9, so this could be true
Peta could have walked 4649.9 and Naomi 4555, so this could be true
Peta could have walked 4555 and Naomi 4555, so this could be true.
All values here are in the ranges of (a)

Find the values of w, x and y.
Answer:
w= 27.47 degree
x=9.99 cm
y=12.02 cm
Step-by-step explanation:
The value of w:
In a right-angled triangle [tex]\tan \theta = \frac {\text{Perpendicular}}{\text{Base}}[/tex]
[tex]\tan w = \frac {\text{Perpendicular}}{25+9}\;and \; \tan 63 = \frac {\text{Perpendicular}}{9}[/tex]
So, [tex]34 \tan w = 9\tan (63)[/tex]
[tex]\tan w = (9/34)\tan(63)=0.52 \\\\w=\tan^{-1}(0.52) \\\\[/tex]
w= 27.47 degree
The value of x:
In a right-angled triangle [tex]\sin \theta = \frac {\text{Perpendicular}}{\text{Hypotaneous}}[/tex]
sin (27) =x/22
x= 22sin(27)
x=9.99 cm
The value of y:
By using Pythagoras theorem,
[tex]y^2+y^2=17^2 \\\\2y^2 = 289 \\\\y^2 =289/2= 144.5 \\\\y=\sqrt {144.5} \\\\[/tex]
y=12.02 cm
An employee at a fast food restaurant noticed that 3 out of every 5 customers ordered onion rings and 2 out of every 5 customers ordered fries. By the end of the employee's shift, she had taken 585 orders. Out of 585 orders, how many were onion rings? Out of 585 orders, how many were fries?
Answer:
Onion rings ⇒ 351 ordersFries ⇒ 234 ordersStep-by-step explanation:
Onion Rings.
3 out of every 5 ordered onion rings and she took 585 orders.
Onion ring orders = 3/5 * 585
= 351 orders
Fries
2 out of every 5 ordered fries
Fries orders = 2/5 * 585
= 234 orders
Fiona has a rectangular garden where the length to width ratio is 3:2.She has 54ft^2 of plants in her garden.Fencing is in sale for $2.50 per foot .How much will she spend to put a fence around her garden
Answer: $75.0
Step-by-step explanation:
Based on the above figures given in the question, the length of the rectangular garden will be 9feet and the width will be 6feet
Length = 9feet.
Width = 6feet
Perimeter = 2 (length + breadth).
= 2(9feet + 6feet)
= 2 (15feet)
= 30 feet
Since fencing is in sale for $2.50 per foot, the amount that she will spend to put a fence around her garden will be:
= $2.50 × 30
= $75.0

are the lines y=4x+4 and y=-4x-2 parallel
Answer:
No they are not, they intersect at some point.
Step-by-step explanation:
Answer:
No these are not parallel
Step-by-step explanation:
Parallel lines have the same slope. 4 and -4 are not the same slope, which means they will intersect. A tool to check your answers such as this is Desmos. It really helps. Search Desmos graphing calculator. Hope this helps.
