Answer:
steps below
Step-by-step explanation:
1. y=-3x + 4 (6,-2)
y' slope: 1/3 (perpendicular)
y' = mx + b
b = y' - mx = -2 - (1/3) x 6 = -4
equation: y' = 1/3 x - 4
2. -2x -8y = 16 (4,5)
8y = -2x - 16 y = -1/4 x - 2
perpendicular line slope: 4
b = y - mx = 5 - 4 x 4 = - 11
equation: y = 4x - 11
3. x+y= 2 (8,5)
y = -x + 2 slope: -1
perpendicular slope: 1
b = y - mx = 5 - 1 x 8 = -3
equation: y = x -3
If J M = 9 and K M = 4 , what is the approximate perimeter of Δ J K L ? 26.2 26.2 29.8 29.8 31.0 31.0 31.7
Answer:
Correct option is (a)
Step-by-step explanation:
According to question in the triangle ΔJKL
JK = 9 and KL =4
according to the condition of triangle sum of two sides must be greater than the third side
Here sum of its two sides is 9 + 4 = 13
⇒ third side must be greater than 13 say 13.2 = JL
therefore, perimeter of triangle ΔJKL is
JK + KL + JL = 9 + 4 + 13.2 = 26.2
Therefore correct option is (a)

4. Christina made a graph to describe the distance she walked on her back packing trip. She plotted miles on the y-axis and the number of days on the x-axis. She graphed a point at (0,0) and another point to show she walked 14 miles in 8 days and drew a line that passes through the points. What is the slope of the line?
Step-by-step explanation:
We have the points (0, 0) and (8, 14).
Rise between the points = 14 - 0 = 14.
Run between the points = 8 - 0 = 8.
Slope of Line
= Rise/Run = 14/8 = 1.75.
The corners of a triangle garden are marked with trees at coordinates (0,3),(3,0), and (4,3). Let a denote the area of the garden, in square units. Which of the following is true?
Given:
Three corner points of a triangular garden are (0,3),(3,0), and (4,3).
To find:
The area of the garden.
Solution:
We know that, area of a triangle is
[tex]A=\dfrac{1}{2}|x_1(y_2-y_3)+x_2(y_3-y_1)+x_3(y_1-y_2)|[/tex]
Let a denote the area of the garden, in square units.
Three vertices of the triangular garden are (0,3),(3,0), and (4,3). So, area of the triangular garden is
[tex]a=\dfrac{1}{2}|0(0-3)+3(3-3)+4(3-0)|[/tex]
[tex]a=\dfrac{1}{2}|0(-3)+3(0)+4(3)|[/tex]
[tex]a=\dfrac{1}{2}|0+0+12|[/tex]
[tex]a=\dfrac{1}{2}\times 12[/tex]
[tex]a=6[/tex]
Therefore, the area of the garden is a=6 square units.

Find the value of x in each diagram
Answer:
A. x = 8.
B. x = 31.
C. x = 32.
Step-by-step explanation:
Here. the sum of the 2 parallel sides of the trapezoid = 2 * length of the middle line segment.
MN + RS = 2PQ
32+ x = 2*20
x = 40 - 32
x = 8.
MN + RS = 2PQ
20 + 42 = 2PQ
2x = 62
x = 31
MN + RS = 2PQ
22 + 42 = 2PQ
2x = 64
x = 32.
The equation of line t is y= -8/7x + 5. line u is perpendicular to t. what is the slope of line u?
Answer:
slope = 7/8
Step-by-step explanation:
perpendicular means line with opposite reciprocal slope ( flip and change signs)
thus
slope of line t = -8/7
flip and change signs
7/8

Answer:
The second option is correct
Step-by-step explanation:
Here, we want to check which of the options is true of the plot
Now, let us take a look at the first option
When we talk of the slope in this case, we are simply talking of the amount he needs to save for each of the months
As we can see, for the initially, he had 900 to save, so what this mean is that at the very beginning, the amount of money he had to save is 900
Hence, the total money he had to save is $900 and this makes the second option correct
Estimate the sum of 945 + 573 + 617 by rounding each number to the nearest hundred.
The estimated sum of 945 + 573 + 617 by rounding each number to the nearest hundred is 2100.
What is rounding off of numbers?We round off numbers to make them easier to remember and it also keeps their value approximately to the place it has been rounded off.
To round off any number to any place we'll look for the digit next to that place and if it is equal to or greater than 5 we'll add one to the previous digit and make all the digits after it zeroes and if the digit is less than 5 we do not add one to the preceding digit and simply make all the digit after it to zeroes.
Given, Are the sum of three integers 945, 573, and 617.
Now, 945 rounded to the nearest hundred is 900, 573 rounded to the nearest hundred is 600 and 617 rounded to the nearest hundred is 600.
Therefore, the sum of 945 + 573 + 617 by rounding each number to the nearest hundred is 900 + 600 + 600.
= 2100.

Answer:
DJ = 48
Step-by-step explanation:
The centroid (J) divides the median into parts that have the ratio 2:1.
DJ : JH = 2 : 1
DJ : (DJ +JH) = 2 : (2+1)
DJ : DH = 2 : 3
DJ = (2/3)DH = (2/3)(72)
DJ = 48
Jenna competes in the high jump. Her best jump in the first meet is 414 feet. Her best jump in the second meet is 456 feet. Enter an expression, using equivalent fractions with a common denominator, to model how much the height of her jump increased.
Answer: [tex]\dfrac{7}{69}[/tex] of height has been increased in second jump from the first jump.
Step-by-step explanation:
In first meet, height of best jump = 414 feet
In second meet, height of best jump = 456 feet
Increase in height = 456 feet - 414 feet
= 42 feet
The fraction of increased in height = [tex]\dfrac{\text{Change in height}}{\text{previous height}}[/tex]
[tex]=\dfrac{42}{414}\\\\=\dfrac{7}{69}[/tex]
Hence, [tex]\dfrac{7}{69}[/tex] of height has been increased in second jump from the first jump.
On a highway, you take 3 seconds to increase your speed from 32 to 35 miles per hour. Your speed increases the same amount each second. The speed limit is 65 miles per hour. What is the domain of the function?
Answer:
1 to 30 seconds
Step-by-step explanation:
3 seconds increases your speed from 32 to 35 miles per hour
Hence 3 seconds = 3 miles per hour(35-32 miles)
1 second = 1 mile
The function for the increase per mile is therefore:
f(x)= 1x
Where x is number of seconds travelled on the highway
The domain of a function are the possible input values for x. Since the speed limit on the highway is 65 miles, the input values for x cannot be more than 30 seconds(current speed is 35 miles per hour, 65-35=30)

Marissa wants to sort 80 beads into 2 cases. The red case has 6 compartments, and the blue case has 8 compartments. How can she sort the beads so the compartments in each case hold the same number of beads and none are left over?
Answer:
5.7 beads
Step-by-step explanation:
Marissa wants to sort 80 beads into 2 cases. The red case has 6 compartments, and the blue case has 8 compartments.
We are told in the Question that:
the compartments in each case hold the same number of beads and none are left over
Hence, let the number of beads in each compartments = x
Therefore:
8x + 6x = 80 beads
14x= 80 beads
x = 80 beads/14
x = 5.7142857143 beads
x ≈ 5.7 beads
Hence, she can sort the beads into 5.7 beads per compartments

The elementary Robotics Club is going on a field trip to the Kennedy Space Center. They will need to rent minivans to get to their destination. There are 35 fourth graders and 40fifth graders in the Robotics Club. Each minivan can only hold 8 people. How many minivans does the school need to rent?
Answer: 10 minivans .
Step-by-step explanation:
Given: There are 35 fourth graders and 40fifth graders in the Robotics Club.
Total people = 35+40 = 75
Since each minivan can only hold 8 people.
Number of minivan required = (Total people) ÷ 8
= 75 ÷ 8
= 9.375≈ 10
Hence, the school needs to rent approx. 10 minivans .
