During summer, when the snow melts, the water level of the Yukon River increases. If the water level of the river increased by 84 centimeters in 6 days, what is the water level increase rate in centimeters per day?
Answer:
14 cm per day
Step-by-step explanation:
To find the water level increase rate in cm per day, divide 84 by 6, since it increased by 84 cm in 6 days:
84/6
= 14
So, the water level increase rate in 14 cm per day
A rectangular field measures 400m by 900m, what is the perimeter of the field:
(A) in meters
(B)kilometers
Answer:
a) 1790 b) 1.79
Step-by-step explanation:
a) you just add to get the perimiter 2(900) + 2(400) to get 1790
b) 1000 meters makes a kilometer so we divide by 1000 and get 1.79 for the kilometers
Write the following equation in standard form.
y=-3/7x-3
[tex]y = - \frac{3}{7}x - 3 \\ [/tex]
Multiply sides by 7

Plus sides 3x
[tex]3x + 7y = 3x - 3x - 21[/tex]
[tex]3x + 7y = - 21[/tex]

Lesson Summary - Rate problems, including constant rate problems, always count or measure something happening per unit of time. The time is always in the denominator. - Sometimes the units of time in the denominators of the rates being compared are not the same. One must be converted to the other before calculating the unit rate of each. -------------------------------------------------------------------------------------- Who walks at a faster rate: someone who walks 60 feet in 10 seconds or someone who takes 5 seconds to walk 25 feet?

Example The double number line shows the amount of clay Jamal uses to make different numbers of identical bowls. Is there a proportional relationship between the amount of clay and the number of bowls? If so, what is the constant of proportionality for pounds of clay per bowl? Clay (pounds) 0 H 2 233 + + + 5 Bowls 0 1 2 3 4 6 All of the ratios for clay: bowls are equivalent. So, there is a proportional relationship. All of the ratios have the same rate, į pound of clay per bowl. The constant of proportionality is 3 1 a. Write an equation representing the pounds of clay, c, that Jamal from the Example needs to make b bowls. V b. Explain how to find the amount of clay Jamal needs to make 8 bowls.
Answer:C: 2/3 B
Step-by-step explanation:
The answers will be ;
a) The required equation will be c = [tex]\frac{2}{3}[/tex] b
b) The amount of clay for 8 bowls will be [tex]5\frac{1}{3}[/tex] pounds.
It is given that the double number line shows the amount of clay Jamal uses to make different numbers of identical bowls.
We have to solve the subparts of the question to get the values.
What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , division , etc.
As per the question ;
The clay needed per bowl = [tex]\frac{2}{3}[/tex] pounds
a)
The equation for clay (c) to make b number of bowls will be ;
c = [tex]\frac{2}{3}[/tex] × b
or
c = [tex]\frac{2}{3}[/tex] b
b)
If there are 8 number of bowls
i.e., b = 8
Then ; amount of clay Jamal needs will be ;
c = [tex]\frac{2}{3}[/tex] × 8
c = [tex]\frac{16}{3}[/tex] pounds
or
c = [tex]5\frac{1}{3}[/tex] pounds
Thus , the answers will be ;
a) The required equation will be c = [tex]\frac{2}{3}[/tex] b
b) The amount of clay for 8 bowls will be [tex]5\frac{1}{3}[/tex] pounds.

What is the equation of the line that passes through the point (-4,-2) and has a slope of -1/2
Answer: y=-1/2x-4
Step-by-step explanation:
If you use point slope formula you get
y+2=-1/2(x+4)
simplify that in y=mx+b and you get
y=-1/2x-4
Find the distance (8,-7) (-4,-2)
Distance = 13 units
Point A: (8, -7)
Point B: (-4, -2)
[tex]\sqrt{(8 + 4)^{2} + (-7 + 2)^{2} }[/tex]
[tex]\sqrt{(12)^{2} + (-5)^{2} }[/tex]
[tex]\sqrt{144 + 25 }[/tex]
[tex]\sqrt{169}[/tex]
[tex]13[/tex]
Answer:
[tex]\boxed {d = 13}[/tex]
Step-by-step explanation:
Use the Distance Formula to help you find the distance between the two following points:
[tex]d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2}}[/tex]
(where [tex](x_{1}, y_{1})[/tex] represents the first point and [tex](x_{2}, y_{2})[/tex] represents the second point)
-Apply the two following onto the formula:
[tex](x_{1}, y_{1}) = (8, -7)[/tex]
[tex](x_{2}, y_{2}) = (-4, -2)[/tex]
[tex]d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}[/tex]
-Solve for the distance:
[tex]d = \sqrt{(-4 - 8)^{2} + (-2 + 7)^{2}}[/tex]
[tex]d = \sqrt{(-12)^{2} + 5^{2}}[/tex]
[tex]d = \sqrt{144 + 25}[/tex]
[tex]d = \sqrt{169}[/tex]
[tex]\boxed {d = 13}[/tex]
Therefore, the distance is [tex]13[/tex].

M Is the midpoint of AB. If AB = 3x +14, and AM = 2x-1, find x and MB.
Answers:
x = 16
MB = 31
==================================================
Work Shown:
M is the midpoint of AB
This means AM is half as long as AB and AM = MB
Put another way, AB is twice as long as AM
AB = 2*AM
3x+14 = 2*(2x-1)
3x+14 = 4x-2
14+2 = 4x-3x
16 = x
x = 16
AM = MB
MB = AM
MB = 2x-1
MB = 2*16-1
MB = 32-1
MB = 31

fb + 3b = d solve for b
Answer: the answer is d/f+3
sorry i couldnt find my work for this problem but i hope it helps !
An equation is formed of two equal expressions. When in the given equation the value fo b is d/(f+3).
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
fb + 3b = d
Take b as a common term from both the terms on the left side of the equation,
b(f + 3) = d
Divide both the sides of the equation by (f+3),
b(f + 3)/(f+3) = d/(f+3)
Simplify,
b = d/(f+3)
Hence, when in the given equation the value fo b is d/(f+3).

There are 4 quarters in 1 dollar the total number of dollars is a function of the number of quarters does this situation represent a linear or nonlinear function? Explain why
Answer:
sample answer: If you make a table of values, you can see that 4 quarters equal 1 dollar and 8 quarters equal 2 dollars. If you graph the data, you will see a straight line. Therefore, this situation represents a linear function with a constant rate of change of 1/4
Step-by-step explanation:
The situation is a representation of the linear function.
What is meant by linear function?A linear function is one that, when graphed, produces a straight line. Thus, non-linear functions are any non-linear functions. Although graphing is the quickest way to determine whether a function is linear or non-linear, we can also determine linearity from its input/output table or equation. A straight line on the coordinate plane is represented by a linear function. For example, y = 3x - 2 denotes a straight line on a coordinate plane and, as such, a linear function.Given that,
One dollar is divided into four quarters.
The total number of dollars is a function of the number of quarters.
Based on the information presented above, we can conclude that when the dollar represents y value and the quarter represents x value
As a result, the slope should be 1/4.
y = 1/4x should be the linear function.
Hence, As a result, we can conclude that the situation is a linear function.
