The Vanderbloom family already traveled 200 miles on their vacation. The total distance that they will travel (d) is a function of their rate of travel (r) and their upcoming travel time (t).
Answer:
See explanation
Step-by-step explanation:
The question is incomplete. However, I'll ask and answer possible questions that emanate from the given parameter.
A possible question is: Write the given information as a function of distance.
We have that;
[tex]Base\ Distance = 200[/tex]
[tex]Time = t[/tex]
[tex]Rate = r[/tex]
The function would be calculated as:
Base Distance + Rate * Time
Substitute values for Base Distance, Rate and Time
This gives:
[tex]200 + r * t[/tex]
[tex]200 + rt[/tex]
Hence;
[tex]Distance = 200 + rt[/tex]
Another possible question is to determine the current distance travelled by the family at a rate of 80 miles per hour for 3 hours.
Here, we have:
[tex]r = 80[/tex]
[tex]t = 3[/tex]
Substitute these values in [tex]Function = 200 + rt[/tex]
[tex]Distance = 200 + 80 * 3[/tex]
[tex]Distance = 200 + 240[/tex]
[tex]Distance = 440[/tex]

Quadrilateral JKLM is a kite as such KM is a perpendicular bisector of J L at point P given that KP =4" JL equals 12" and AML equals 20" was the length of the permenter of the quad JKlM?
Answer:
40 + 4√13
Step-by-step explanation:
A kite is a quadrilateral (has four sides) with two pairs of equal adjacent sides. The longer diagonal of a kite bisects the shorter diagonal.
Since in kite JKLM, diagonal KM bisects JL, hence KM is the longer diagonal.
JP = LP
JL = 12
JL = JP + LP
12 = JP + LP
2JP = 12 (LP = JP)
JP = 6
We can find JK using Pythagoras theorem, hence:
JK² = JP² + KP²
JK² = 4² + 6²
JK² = 16 + 36
JK² = 52
JK = √52 = 2√13
JK = KL = 2√13
ML = JM = 20
Perimeter of kite = JK + KL + ML + JM = 20 + 20 + 2√13 + 2√13
Perimeter of kite = 40 + 4√13

Mei earn $2 less than three times as much as Olivia. Shane earns twice as much as mei. Together they earn $594 per week. How much does each person earn per week?
***
Step-by-step explanation:
let x=amt Olivia earns
3x-2=amt Mei earns ($2 less than three times as much as Olivia).
2(3x-2)=amt Shane earns (twice as much as mei)
..
x+3x-2+2(3x-2)=594
x+3x-2+6x-4=594
10x=600
x=60

the expression.
What is the slope of the line represented by 9x - 14y = 28?
Answer:
The slope of the line is [tex]\displaystyle \frac{9}{14}[/tex].
Step-by-step explanation:
We are given the line in standard form:
[tex]9x - 14y = 28[/tex]
We need to get this into slope-intercept form in order to determine the slope of the line.
Slope-intercept form is [tex]y = mx + b[/tex], where m is our slope and b is the y-intercept.
Therefore, we need to get:
[tex]9x - 14y = 28[/tex]converted to:
[tex]y = mx +b[/tex].[tex]\displaystyle 9x - 14y = 28\\\\-14y = -9x + 28\\\\\frac{-14y}{-14}=\frac{-9x+28}{-14}\\\\y = \frac{9}{14}x-2[/tex]
Therefore, by solving the equation in slope-intercept form, we see that m equals 9/14, so our slope is [tex]\displaystyle \frac{9}{14}[/tex].

Eloise bought 3 boxes of crackers to share with her friends over the weekend. They ate 1/2 box of crackers on Saturday and 2/3 box of crackers on Sunday.
How many boxes of crackers were left over?
1 3/5 boxes
1 5/6 boxes
2 3/5 boxes
2 5/6 boxes
Answer:
C.) 1 5/b boxes
Number of boxes left over
= 3 - 1/2 - 2/3
Convert each fraction to one in terms of the LCM:
= 18/6 - 3/6 - 4/6
= 11/6
= 1 5/6 boxes.
The solution is Option B.
The number of boxes of crackers left with Eloise is 1 5/6 boxes of crackers
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of boxes of crackers left with Eloise be = A
Now , the total number of boxes of crackers be = 3 boxes
The number of boxes of crackers ate on Saturday = 1/2
The number of boxes of crackers ate on Sunday = 2/3
So , the equation will be
Number of boxes of crackers left with Eloise A = total number of boxes of crackers - number of boxes of crackers ate on Saturday - number of boxes of crackers ate on Sunday
Substituting the values in the equation , we get
Number of boxes of crackers left with Eloise A = 3 - 1/2 - 1/3
On simplifying the equation , we get
Number of boxes of crackers left with Eloise A = 5/2 - 2/3
Number of boxes of crackers left with Eloise A = ( 15 - 4 ) / 6
Number of boxes of crackers left with Eloise A = 11/6
Number of boxes of crackers left with Eloise A = 1 5/6 boxes
Therefore , the value of A is 1 5/6 boxes
Hence , the number of boxes left is 1 5/6 boxes of crackers

A model car is 12 inches
long. Using a scale of
3inches : 4 feet, how long
is the actual car?
A. 1 foot
B. 9 feet
C. 16 feet
Answer: C
Step-by-step explanation: If a car is 12 inches a room could possibly be 16 feet and a room and a car might or if not might have the same width
I hoped i helped :)
Answer: C) 16 feet
=======================================================
Work Shown:
3 inches on paper = 4 feet in real life
Multiply both sides by 4 so that the "3 inches on paper" turns into "12 inches on paper"
We get
4*(3 inches on paper) = 4*(4 feet in real life)
12 inches inches on paper = 16 feet in real life
This leads to the answer C) 16 feet.
--------------------------
Alternative Method:
(3 in on paper)/(4 ft in real life) = (12 in on paper)/(x ft in real life)
3/4 = 12/x
3*x = 4*12 ... cross multiply
3x = 48
x = 48/3 .... dividing both sides by 16
x = 16
The car's length is 16 feet in real life.

Step-by-step explanation:
The line is negative, so you will have a negative slope
The line is crossing the y- axis at 2 so the y- intercept is 2.
Now do rise over run or rise/run
The lines rise is 2 and the run is 4
2/4 = 1/2 and since the line is negative the slope is negative -1/2

What’s the solution of x+y=29 and y=4x-11
Answer:
x = 8
y = 21
Step-by-step explanation:
y = 4x − 11
x + y = 29
Solve for x:
x + y = 29
x + 4x − 11 = 29
5x − 11 = 29
5x = 40
x = 8
Solve for y:
y = 4x − 11
y = 4 × 8 − 11
y = 21
