Step-by-step explanation:
Phil is riding his bike. He rides 25 miles in 2 hours, 37.5 miles in 3 hours, and 50
miles in 4 hours. Find the constant of proportipnality and write an equation to
describe the situation. Let x represent the number of hours.
The equation that describes the relationship is y =
The constant of proportionality (known as "speed" in this case) is 12.5 miles per hour.
The equation is
d
=
12.5
×
t
Explanation:
To find the constant of proportionality, divide one value in each pair by the other. If this relationship is a true direct proportionality , when you repeat these for every pair, your will come up with the same value:
For example
25
miles
÷
2
hours
=
12.5
miles
hour
A direct proportionality will always result in an equation that resembles this:
y
=
k
x
where
y
and
x
are the related quantities and
k
is the constant of proportionality. If you draw a graph using the values you have, the graph will show a straight line the passes through the origin. The slope of this line will be the constant of proportionality. (And if the values given are real physical quantities, this constant will contain important information about the situation you are studying!)

Find the area of this triangle. Round to the nearest tenth. 9.5 yd 23 yd
Please help!
Answer:
[tex]Area=\frac{ab}{2} \\\\area=\frac{9.5.23}{2} \\\\answer=108.8 yd^{2}[/tex]
Step-by-step explanation:
I hope this helps ^_^
The area of the triangle is 108.7 square yards.
What is the area of the triangle?Let a, b, and c is the sides of the triangle.
The area of the triangle is given as
S = (a + b + c) / 2
[tex]\rm A = \sqrt{s(s - a)(s - b)(s -c )}[/tex]
The third side of the triangle will be
c² = a² + b² - 2ab cos θ
c² = 9.5² + 23² - 2 × 9.5 × 23 × cos 85°
c² = 619.25 - 38.09
c² = 581.16
c = 24.11 yd
Then the area of the triangle will be
S = (9.5 + 23 + 24.11) / 2
S = 56.61 / 2
S = 28.3
Then the area will be
[tex]\rm A = \sqrt{28.3(28.3 - 24.11)(28.3 - 23)(28.3 - 9.5)}[/tex]
Simplify the expression, then the value will be
A = √11815.01
A = 108.7 square yd
The area of the triangle is 108.7 square yards.

Can someone please help me pleaseeee!
Answer:
y=-1.7x+8
Step-by-step explanation:
An equation of a line is y=mx+c
m is the gradient and c is the y intercept, which is where the line intercepts y.
you work out m getting two points and then subtracting y - y ÷ x - x
So in this graph, if we chose points (6,-2) and (3,3) then we would do this equation.
[tex] \frac{3 - - 2}{3 - 6} = \frac{5}{ - 3} = - 1.7[/tex]
So m = -1.7
c = 8 because it goes through 8 in y.
So the equation is y=-1.7x+8
Monica deposits $100 into a savings account that pays a simple interest rate of 3.8%. Paul
deposits $200 into a savings account that pays a simple interest rate of 2.5%. Monica says that
she will earn more interest in 1 year because her interest rate is higher. Is she correct? Justify your
response
Answer:
Paul
Step-by-step explanation:
Paul earn more than monica. Though he is getting less interest but because of his higher initial amount he is getting more return.
Computing the return of both
Monica return is 100*3.4%= $3.4 in a year
Paul return is 200*%2.2= $4.4 in a year.

Answer:
$109.97
Step-by-step explanation:
Each straight piece of wire is the diagonal of a square that is 3" on a side. The Pythagorean theorem tells you the length of that diagonal is ...
d = √(3^2 +3^2) = √18 = 3√2 . . . inches
There are 4 such diagonals on each trivet, so the total length of wire for 12 trivets is ...
(12)(4)(3√2) = 144√2 . . . inches
At a cost of $0.54 per inch, the total cost for 12 trivets will be ...
($0.54)(144√2) = $109.97
The cost of the copper wire for making 12 trivets is $109.97.
