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.
Answers
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.
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
Answers
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)

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
Which equation is a linear function?
y=2^x -1
y=x/2-5
y=2/x +3
y=x^2 +7
Answers
Answer:
Second Choice.
Step-by-step explanation:
[tex]y = mx + b[/tex]
That is the linear function. Any coefficients with higher degrees won't be considered as a linear function.
So we can cut out the first and last choice.
Then we have only two choices which are
[tex]y = \frac{x}{2} - 5 \\ y = \frac{2}{x} + 3[/tex]
The second equation is called Rational Function where a variable is a denominator.
Therefore, the correct answer is second choice.

Multiple Choice The perimeter of a square
is 68 m. If one side is represented by 3x + 2,
what is the value of x?
A 3
B 5
C 4
D 6
E 10
Answers
Answer:
The answer is B, 5.
Step-by-step explanation:
3x+2 is per side. A square has 4 sides. 3x+2 times 4 is 12x+8 (using the distributive property).
12x+8 = 68
12x = 60
divide both sides by 12...
60/12 = 5.
Therefore x =5
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?
Answers
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)

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?
Answers
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 .

Solve for x. -4(-2x - 2) + x - 2 = -48
Answers
Answer:
x = -5.7778
Step-by-step explanation:
1) 8x + 8 + x -2 = 48 (You multiply the -4 into both -2x and -2, thus getting rid of the brackets)
2) 9x + 6 = -48 (Add the two values of x (8x + x) and then subtract the 2 from 8 = 6)
3) 9x =-46 - 6 (Move the 6 mover, which will change its sign from a (+) to a (-6))
4) 9x = -52 (Do the expression, and you get -52)
5) x = -52 / 9 (Isolate the x, by dividing both sides by it)
6) x = -5.7778 (Round the answer)
