A plane travels 3400 miles in 8 hours. How far would it travel in 6 hours at this rate? What is the Unit Rate: Write the equation: How far will the plane travel in 6 hours: (disance in miles)
Answer:
Unit rate 425 miles/hr, equation: m = 425h, in 6 hours plane will travel 2550 miles
Step-by-step explanation:
Set up a proportion, so 3400/8 = x/6 so x = 2550
Tell which term you would add or subtract on both sides side of the equation so that the variable is only on one side.

Step-by-step explanation:
Hello There!
First things first, we should find the rate of change / slope
given two points we can find the slope by using the slope formula which is
(let m be slope)
[tex]m = \frac{y_2-y_2}{x_2-x_2}[/tex]
To find the slope all we have to do is plug in the points
(1,5),(2,10)
remember the first numbers in an ordered pair are the x values and the second numbers are the y values
we also plug in the points of the second ordered pair first so
[tex]m=\frac{10-5}{2-1} \\10-5=5\\2-1=1\\m=\frac{5}{1} or5[/tex]
Knowing the slope we can create an equation to find the x value (a)
y=5x
given the y value we plug in y and solve for x
15=5x
divide each side by 5
15/5=3
5x/5=x
we're left with
x=3
so we can conclude when y =15 x = 3 therefore 3 is your answer

In January, a puppy weighed 4kg.
Three months later, the same puppy weighed 5kg.
What was the percentage increase in the puppy's weight?
Answer:
25%
Step-by-step explanation:
5kg=5000g(a)
4kg=4000g(b)
p=percent
a=b+bxp/100
5000=4000+4000xp/100
5000-4000=40xp
1000=40xp
p=1000/40
p=25
R:25%
The percentage increase in the puppy's weight is 25% and this can be determined by using the unitary method.
Given :
In January, a puppy weighed 4kg. Three months later, the same puppy weighed 5kg.The following steps can be used to determine the percentage increase in the puppy's weight:
Step 1 - The unitary method can be used to determine the percentage increase in the puppy's weight.
Step 2 - According to the given data, in January, a puppy weighed 4kg. Puppy's weight is 4kg in January which is 100%.
Step 3 - So, if 4 kg is 100% then 5kg is equal to:
[tex]=\dfrac{100}{4}\times 5[/tex]
Multiply 100 by 5 in the above expression.
[tex]=\dfrac{500}{4}[/tex]
Divide 500 by 4 in the above expression.
= 125%
Step 4 - So, the percentage increase in the puppy's weight is:
= 125 - 100
= 25%

Answer:
Step-by-step explanation:
The sin(30) = 1/2
The sin(30) = 1/2 = opposite / hypotenuse
Opposite = 7
hypotenuse = opposite / sin(30)
hypotenuse = 7 / (1/2) = 7 *2 / 1 = 14
The long side can be found using the Pythagorian Theorem.
a^2 + b^2 = c^2
a = 7
b = ?
c = 14
14^2 = 7^2 + b^2
196 - 49 = b^2
147 = c^2
147 = 3*7 *7
sqrt(b^2) = sqrt(3*7*7)
b = 7 sqrt(3)

Answer:
Slope.
Step-by-step explanation:
mx+b
Answer:
Slope
Step-by-step explanation:
The equation of lines are normally formatted in "slope-intercept form"
(y = mx + b)
The b in the equation would be the y-intercept of the line.
The m represents the slope.
The x and y can be replaced with any x and y value from the line (if necessary)

In a maths class the girl to boy is 7:5 If there are 20 boys how many girls are in the class
Answer:
Let the total no of girls be x
the number of boys=7:5
total no of students =20
now,
no of girls =7/5=x/20
or, 20*7=5x
or 140=5x
or,x=140/5=28
therefore the number of girls =28

Find the value of x.
please help
Answer:
123 degrees
Step-by-step explanation:
Well, since we have a 4 sided figure, we know that the sum of the interior angles is 360 degrees.
(n-2)*180=(4-2)8180=360
Okay we are given 3 angles
120+43+74= 237
that means that x= 360-237
x=123 degrees

What is the missing polynomial ?-(20-4x5x^2)=20-7x^2
Answer: [tex]-2x^2-4x+40[/tex]
Step-by-step explanation:
Suppose the missing polynomial be f(x)
So, we can write
[tex]\Rightarrow f(x)-(20-4x+5x^2)=20-7x^2\\\Rightarrow f(x)=20-7x^2+(20-4x+5x^2)\\\Rightarrow f(x)=-2x^2-4x+40[/tex]
