Miles and kilometers are twi different scales for measuring distances. A 5-kilometer race is approximately 3.1 miles, and a 10-kilometer race id approximately 6.2 miles. Write an equation that shows the approximate distance in kilometers as a function if the distance in miles
Answer:
[tex]x=\dfrac{y}{0.62}[/tex]
Step-by-step explanation:
[tex]5\ \text{km}=3.1\ \text{miles}\\\Rightarrow 1\ \text{km}=\dfrac{3.1}{5}=0.62\ \text{miles}[/tex]
[tex]10\ \text{km}=6.2\ \text{miles}\\\Rightarrow 1\ \text{km}=\dfrac{6.2}{10}=0.62\ \text{miles}[/tex]
Let [tex]y[/tex] be the distance in miles. So distance in km is given by
[tex]x=\dfrac{y}{0.62}[/tex].
The equation that shows the approximate distance in kilometers as a function if the distance in miles is [tex]x=\dfrac{y}{0.62}[/tex].

A garden patio is covered wit grey slabs and yellow slabs .1/5 of the slabs are grey a)write down the ratio of grey slabs to yellow slabs give your answer in its simplest form b)there are 55 slabs in total work out the number of yellow slabs
Answer:
1:u
Step-by-step explanation:
Grey slabs = 1/5 of total slab
Say total slab = x
Then,
Grey slabs = 1x/5
We can represent
Yellow slabs = u/5
Then ratio of Grey to yellow would be;
Gray slabs / Yellow slabs = (1x/5)/(u/5)
=1/u
= 1:u
Since there are 55 slabs in total, then
Yellow slab would be = 55/5 = 11

Identify the asymptotes, domain, and range
f(x)=-1/x+4
Just do number 2 at the least, if you want to do more ill give brainliest
1.
[tex]f(x)=\dfrac1{x-1}=\dfrac1{x-1}+0[/tex]
x-1 = 0 for x = 1
so:
Vertical asymptote: x = 1
Domain: Dom f = R\{1} {or: Dom f = (-∞, 1)∪(1, ∞)}
Horizontal asymptote: y = 0
Range: Ran f=R\{0} {or: Ran f = (-∞, 0)∪(0, ∞)}
2.
[tex]f(x)=\dfrac{-1}{x}+4=\dfrac{-1}{x-0}+4[/tex]
x-0 = 0 for x = 0
so:
Vertical asymptote: x = 0
Domain: Dom f = R\{0} {or: Dom f = (-∞, 0)∪(0, ∞)}
Horizontal asymptote: y = 4
Range: Ran f=R\{4} {or: Ran f = (-∞, 4)∪(4, ∞)}
3.
[tex]f(x)=\dfrac{1}{x+3}-3[/tex]
x+3 = 0 for x = -3
so:
Vertical asymptote: x = -3
Domain: Dom f = R\{-3} {or: Dom f = (-∞, -3)∪(-3, ∞)}
Horizontal asymptote: y = -3
Range: Ran f=R\{-3} {or: Ran f = (-∞, -3)∪(-3, ∞)}
4.
[tex]f(x)=\dfrac{-1}{x+5}-6[/tex]
x+5 = 0 for x = -5
so:
Vertical asymptote: x = -5
Domain: Dom f = R\{-5} {or: Dom f = (-∞, -5)∪(-5, ∞)}
Horizontal asymptote: y = -6
Range: Ran f=R\{-6} {or: Ran f = (-∞, -6)∪(-6, ∞)}
4.
[tex]f(x)=\dfrac{-1}{x+1}+3[/tex]
x+1 = 0 for x = -1
so:
Vertical asymptote: x = -1
Domain: Dom f = R\{-1} {or: Dom f = (-∞, -1)∪(-1, ∞)}
Horizontal asymptote: y = -6
Range: Ran f=R\{3} {or: Ran f = (-∞, 3)∪(3, ∞)}
5.
[tex]f(x)=\dfrac{1}{x+4}-2[/tex]
x+4 = 0 for x = -4
so:
Vertical asymptote: x = -4
Domain: Dom f = R\{-4} {or: Dom f = (-∞, -4)∪(-4, ∞)}
Horizontal asymptote: y = -2
Range: Ran f=R\{-2} {or: Ran f = (-∞, -2)∪(-2, ∞)}

Your Olympic team wins 48 medals in the spring. The medals are gold, silver, and bronze in a ratio of 2 : 1 : 5. How many of each medal did your team win?
Answer:
12, 6 and 30
Step-by-step explanation:
Step one:
given data
Number of medals = 48 medals
The given ratio is = 2:1:5
The total ratio is = 2+1+5= 8
Step two;
Applying the part to all method
for Gold we have
2/8=x//48
cross multiply
8x= 48*2
divide both sides by 8
x= 96/8
x= 12
gold is 12
for silver we have
1/8=x//48
cross multiply
8x= 48*1
divide both sides by 8
x= 48/8
x= 6
silver is 6
for bronze we have
5/8=x/48
cross multiply
8x= 48*5
divide both sides by 8
x= 240/8
x= 30
Bronze is 30

1. ABCD is an isosceles trapezoid. m < A = 6x + 12 and m < d = 2x + 20. Angles B&C are congruent. What is the measure of angles B&C?
2. QRST is a rectangle. RS = 12k +5 and QT = 145. what is the value of 'k'?
Answer:
∠ B = 123°, ∠ D = 57°
Step-by-step explanation:
Each lower base angle is supplementary to the upper base angle on the same side.
∠ A and ∠ D are on the same side, then
6x + 12 + 2x + 20 = 180
8x + 32 = 180 ( subtract 32 from both sides )
8x = 148 ( divide both sides by 8 )
x = 18.5
Thus
∠ A = 6x + 12 = 6(18.5) + 12 = 111 + 12 = 123°
∠ D = 2x + 20 = 2(18.5) + 20 = 37 + 20 = 57°
The lower base angles and the upper base angles are congruent, so
∠ B = ∠ A = 123°
∠ C = ∠ D = 57°
Answer:
Step-by-step explanation:
#1). It could be good to provide us with the picture, because the answer depends from the angle we choose for letter A.
--- If angle A is acute, then m∠A = m∠D
and
6x + 12 = 2x + 20 ⇒ x = 2
m∠A = m∠D = 24°
m∠B = m∠C = 180° - 24° = 156°
--- If angle A is obtuse, then m∠A + m∠D = 180°
and
6x + 12 + 2x + 20 = 180 ⇒ x = 18.5
m∠A = m∠B = 6(18.5) + 12 = 123°
m∠D = m∠C = 2(18.5) + 20 = 57°
#2). 12k + 5 = 145
12k = 140
k = [tex]\frac{35}{3}[/tex] = [tex]11\frac{2}{3}[/tex]
Find the quotient.

write the equation of the graphed in NO SPACES ALL LOWERCASE
Help !!
Answer:
The equation of the graphed line is:
y = 2Step-by-step explanation:
From the graph, it is clear that the line is a horizontal line at y = 2.
We know that a horizontal line has a slope of 0 because the value of y does not change no matter what the value of x we put in.
In other words, the equation of the horizontal line would always get the form:
y = k
where k is the y-intercept of the line.
Determining the y-intercept of the line:
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 2
Thus, the y-intercept k = 2
Thus, if we substitute the y-intercept k = 2 in the equation y = k, we get the equation
y = 2
Therefore, the equation of the graphed line is:
y = 2PLEASE HELP me!!! can give brainliest!
Joyce would like to invest her money in a savings account. The function A (t) = 900(1.03)^t represents the amount of money joyce will have in her savings account after t years. How long will it take Joyce to have $1200 in her account? Around your answer to the nearest tenth of a year. ( use desmos )
Answer:
9 years ( approximately)
Step-by-step explanation:
900(1.03)^t = 1200
(1.03)^t= 1.33
( 1.03)^t= ( 1.03)^9
So, t= 9

200 ÷ 70 ONLY THE ANSWER AND REMAINDER IF THERE IS.
Answer:
2 remainder 60!
Step-by-step explanation:
is 4 a factor of 72
Answer:
Yes
Step-by-step explanation:
Yes. 72 divided by 4 would be 18, so it is a factor
Answer:
Yes
Step-by-step explanation:
Yes because 4 x 18 = 72
72 divided by 18 = 4
I know this because if you multiply 4 x 18 you will get 72. To check you can do the inverse operation, which is division, so with that being said, 72 divided by 18 = 4.
I explained to so you can have a better understanding. Have a great day!
PLEASE HELP ANYONE!!!Write the exponential regression representing the population of Lazy Town as a function of time in years
Given:
[tex]R^2=0.92,a=8000,b=0.9[/tex].
Exponential regression model is
[tex]y_1\sim a(b)^{x_1}[/tex]
To find:
The exponential regression representing the population of Lazy Town as a function of time in years.
Solution:
We have, [tex]a=8000,b=0.9[/tex].
Exponential regression model is
[tex]y_1\sim a(b)^{x_1}[/tex] ...(i)
Putting [tex]a=8000[/tex] and [tex]b=0.9[/tex] in (i), we get.
[tex]y_1\sim 8000(0.9)^{x_1}[/tex]
Thus, [tex]y_1\sim 8000(0.9)^{x_1}[/tex] is the required exponential regression representing the population of Lazy Town as a function of time in years.

Answer:
c= 7 p=4
Step-by-step explanation:
3p + 4c = $40
therefore
15p + 20c = 200
5p + 2c = 34
therefore
15p + 6c = 102
14c = 98
98/14=7
c = 7
5p + 2(7) = 34
5p + 14 = 34
- 14 - 14
5p = 2020/5= 4
p = 4
