Answer:
a. y = x/50
b. 7
Step-by-step explanation:
Here, we have a direct proportional relationship
a) y = kx
where k is the proportionality constant
10 = k * 500
500k = 10
k =
10/500 = 1/50
The formula is;
y = x/50
b. when x = 350
y = 350/50
y = 7

Marcy, a 7th grader, decided to be a rebel one day and climb a 20-foot ladder up to the roof of the school in-between classes. When she decided to do this, Mr. Hill’s sixth sense was activated, and he decided to go check the roof area. Marcy climbed at a steady rate and was 14 feet up the ladder after 28 seconds of climbing when Mr. Hill burst into the room, saw her, and yelled for her to stop. Surprised, Marcy slipped and fell down the ladder at a steady rate for 2 seconds before she caught herself 6 feet up the ladder. A few minutes later, she was safe in ISS. Choose an equation for the relationship between Marcy’s distance climbing up the ladder and time.
Answer:
69 feet per second
Step-by-step explanation:
Answer:
wow ok so- thats my name- i'd climb to the roof, yes. aand the answer is gonna be below.
Step-by-step explanation:
14 - 6 = 8
28 - 2 = 26

Willa bought 5 tops that cost $72 after she applied a $20-off coupon. The tops all cost the same amount. Which equation can be used to find the cost in dollars of each top?
A5t + 20 = 72
B5t - 20 = 72
C20t = 5 = 72
D20t - 5 = 72
Answer:
B
Step-by-step explanation
5 tops minus the 20 from coupon, to get the total
Can you help me please
Answer:
Step-by-step explanation:
y ∝ x
y= k*x
As given y =-16, x=4 putt in above formula to get value of K
k = -16/4 = -4
Hence also given that ,
y =20
k = -4
x= ?
x= y/k (using formula)
x =20 / -4
x = -5

Blaise bought a used car for $3,250. He added a turbocharger that cost t dollars and a new air intake manifold that cost $178, bringing the total cost to $3,587. This situation can be represented by the equation $3,250 + $178 + t = $3,587. How much did the turbocharger cost?
Answer:
t = $159
Step-by-step explanation:
3587-3250-178 = t
t = 159
Change to y = mx + b form. 3y - 3x = 9
Answer:
y = x+3
Step-by-step explanation:
3y-3x = 9
3y-3x+3x = 9+3x
3y = 3x+9
3y/3 = 3x/3+9/3
y = x+3
Hey there!
The answer is [tex]y=x+3[/tex]
[tex]3y-3x=9[/tex]
[tex]\frac{3y}{3} -\frac{3x}{3} =\frac{9}{3}[/tex]
[tex]y-x=3[/tex]
[tex]y-x+x=3+x[/tex]
[tex]y=x+3[/tex]

. Toby invested £4500 for 2 years in a savings account. He was paid 4% per annum COMPOUND
interest. How much did Toby have in his savings account after 2 years?
Answer:
£4867.2
Step-by-step explanation:
Given data
P= £4500
T=2 years
R= 4%
The compound interest expression
A=P(1+r)^t
substitute
A= 4500(1+0.04)^2
A=4500(1.04)^2
A=4500*1.0816
A=£4867.2
Hence the balance is £4867.2
Answer:
P(1+r/100)^n - P
4500(1+4/100)^{2}-4500 =367.2

The value of x =
60°
5
x
30°
Answer:
10
Step-by-step explanation:
with reference angle 30°
perpendicular (p) = 5
hypotenuse (h) = x
Now
sin 30° = p / h
1 / 2 = 5 / x
x = 10
Hope it will help :)
Find each of the trigonometric ratios. I am going to give brainliest to whoever gets this right.
Answer:
Step-by-step explanation:
sin(Z) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{YZ}{XZ}[/tex]
= [tex]\frac{9}{15}[/tex]
= [tex]\frac{3}{5}[/tex]
cos(Z) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{XY}{XZ}[/tex]
= [tex]\frac{12}{15}[/tex]
= [tex]\frac{4}{5}[/tex]
tan(Z) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{XY}{YZ}[/tex]
= [tex]\frac{9}{12}[/tex]
= [tex]\frac{3}{4}[/tex]
sin(X) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{YZ}{XZ}[/tex]
= [tex]\frac{12}{15}[/tex]
= [tex]\frac{4}{5}[/tex]
cos(X) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{XY}{XZ}[/tex]
= [tex]\frac{9}{15}[/tex]
= [tex]\frac{3}{5}[/tex]
tan(X) = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
= [tex]\frac{YZ}{XY}[/tex]
= [tex]\frac{12}{9}[/tex]
= [tex]\frac{4}{3}[/tex]

Step-by-step explanation:
Corey spent $17.00, inculding sales tax, on 2 sanwiches cost $5.25 each and the total sales tax was $0.92. What was the cost of each drink.
Answer:
Well to start you already know the sandwich cost 5.25 and the total sales tax .92.
To find the cost of each drink
5.25 x 2= 10.50
10.50+.92=11.42
17.00-11.42= 5.58
5.58/3= 1.86
So the cost per Drink is $1.86

So, she needed a foil of double the dimensions of the rectangular piece of paper to wrap the gift. Let's say the dimensions of the piece of paper were 12 by 10. Double both those and you get 24*20. Which is 480, and that makes sense since you have two dimensions you are doubling, which is essentially the area times 4.
please help me put these in order if u can
Answer:
5x+8y=480
5(16)+8y=480
80+8y=480
8y=40
y=50
Step-by-step explanation:
x= kids ticket sold
y= adult tickets sold
5x+8y = sales
Plug in 16 for x and 480 for sales
5(16)+8y= 480
Solve for y
80+8y=480
400=8y
y=50

What is the measure of angle n?
Answer:
45 degrees
Step-by-step explanation:
The exterior angles of any polygon is 360 degrees. There are 8 exterior angles, so you have:
8n = 360
divide both sides by 8
n = 45 degrees
Answer: 45
Step-by-step explanation:
Octagon 8 angles
All exterior angles add up to 360 degrees
Meaning we divide
360/8 = 45
If the nurse to patient ratio in a long term care unit is 3:15, how many nurses would you expect to see in a unit with 72
Which angle has the same measurement as angle DEA, and how do you know that the measurement is the same? Will mark Brainly or how ever you call it.
Answer:
∠DEA=∠BAC
Step-by-step explanation:
∠DAE=∠BCA (corresponding angles)
Angles in a triangle add up to 180:
Angles in ΔDAE=Angles in ΔABC
∠DAE+∠EDA+∠DEA=∠BCA+∠ABC+∠BAC
∠EDA+∠DEA=∠ABC+∠BAC (since ∠DAE=∠BCA, we can cancel them out)
∠DEA=∠BAC (∠EDA=∠ABC=90)

What is the measure of arc ADC?
Answer: The answer would be 315 if you are looking for the remaining angle if you're looking for the actual measure of the remaining section of the circumference, then the answer would be approximately 49.481
Step-by-step explanation:
Because the remainder of the circle is the answer you're looking for, you can subtract 45 from 360 and get your answer, whenever you know the measure of one angle, and you are looking for the remaining angle, you can use this strategy.
You already know the angel of the remainder, and you can use this to find the section of the circumference shown. First you need to find the circumfrence, to do this you must use the equation C equals pi radius squared. You put 9 in for the radius and you get approximately 56.55, you then divide this by 360 and get 0.15708333, you then multiply it by the angle you found early, 315. You then should get approximately 49.48125.
Answer:
315
Step-by-step explanation:
The other answer is correct, a minor clarification
measure of an arc is an angle, if the text had wanted the physical length of the arc ADC it would have asked for arc length of ADC
Trigonometric functions
Answer:
in mathematics,the trigonometric functions are real function which relate an angle of a right angle triangle to ratios of two side lengths.They are widely used in all sciences that are related to geometry,such as navigation,solid mechanics,celestial mechanics,geodesy,and many others.
Every two years, there is a local election in a small town. In 2015, a total of 29,000 voters turned out in the election. In 2017, the number of voters decreased by 16%. In 2019, the number of voters increased by 22%. How many voters turned out in the election for 2019?
Answer:
29730 voters
Step-by-step explanation:
so:
in 2017- 16/100=0.16 x 29,000=4640 so 29,000-4640=24360 voters
in 2019-22/100=0.22 x 24369=5361.18 so 24369+5361.18=29730.18 voters
