Find the result when 68 is decreased by 50%.
Answer:
34
Explanation:
When 68 is decreased by 50%, that would mean that it is decreasing by half of that number. Half of that number would be 34 and that would be your answer.

Answer:
<R=56 degrees; <Q=62 degrees; <S=62 degrees
Step-by-step explanation:
5x+12=4x+22 (This is because the two angles are congruent to each other.)
x+12=22
x=10
Now, plug it in.
5(10)+12=50+12=62 degrees
62(2)=124 degrees (This is because the two angles are congruent and equal)
180-124=56 degrees

Answer:
y = x - 4
Step-by-step explanation:
The equation is just y = x shifted down 4 units, so it's y = x - 4. If you have to use all of the symbols, you can write "y = x * 1 - 4 + 0". Otherwise, use the one under "Answer" as it is shorter
Answer:
Step-by-step explanation:
you find slope (y1-y2)/(x1-x2) = (0-1)/(4-5) = -1/-1= 1
then you take a point (4,0)
y-0 = 1(x-4)

Goran drove 660 miles in 12 hours.At the same rate, how long would it take him to drive 385 miles?
Answer:
7 Hour
Step-by-step explanation:
Divide 660 by 12 to get the unit rate.
660 divided by 12 equals 55.
Hence, in 1 hour, Goran drives 55 miles. Next, divide 385 by 55 to get 7.
Therefore,Goran 7 hours to drive 385 miles.
Answer:
Hello, There!
First we have to find Out How fast Goran can go in one hour and If we dived by 660 ÷ 12 = 55
Now We know that Goran Drove [tex]55[/tex] Miles in 1 hour
Since We figured out How fast Goran can go in one miles we can add/multiply to get your final Answer
We can add like this 55, 110, 165, 220, 275, 330, 385
Now we Can Stop because the Question says "Goran drove 660 miles in 12 hours.At the same rate, how long would it take him to drive 385 miles"
And Counting the times we Added we Have the Answer 7
Therefore, It took Goran 7 hours Drive 385 Miles
A jumping spider's movement is modeled by a parabola. The spider makes a single jump from the origin and reaches a maximum height of 10 mm halfway across a horizontal
distance of 80 mm.
Part A: Write the equation of the parabola in standard form that models the spider's jump. Show your work. (4 points)
Part B: Identify the focus, directrix, and axis of symmetry of the parabola. (6 points)
A parabola is a mirror-symmetrical U-shape.
The equation of the parabola is [tex]\mathbf{y = -\frac{1}{640}(x - 80)^2 + 10}[/tex]The focus is [tex]\mathbf{Focus = (80, -1760)}[/tex]The directrix is [tex]\mathbf{y = \frac{1}{640}}[/tex]The axis of the symmetry of parabola is: [tex]\mathbf{x = 80}[/tex]From the question, we have:
[tex]\mathbf{Vertex: (h,k) = (80,10)}[/tex]
[tex]\mathbf{Origin: (x,y) = (0,0)}[/tex]
The equation of a parabola is:
[tex]\mathbf{y = a(x - h)^2 + k}[/tex]
Substitute the values of origin and vertex in [tex]\mathbf{y = a(x - h)^2 + k}[/tex]
[tex]\mathbf{0 = a(0 - 80)^2 + 10}[/tex]
[tex]\mathbf{0 = a(- 80)^2 + 10}[/tex]
[tex]\mathbf{0 = 6400a + 10}[/tex]
Collect like terms
[tex]\mathbf{6400a =- 10}[/tex]
Solve for a
[tex]\mathbf{a =- \frac{1}{640}}[/tex]
Substitute the values of a and the vertex in [tex]\mathbf{y = a(x - h)^2 + k}[/tex]
[tex]\mathbf{y = -\frac{1}{640}(x - 80)^2 + 10}[/tex]
The focus of a parabola is:
[tex]\mathbf{Focus = (h, \frac{k+1}{4a})}[/tex]
Substitute the values of a and the vertex in [tex]\mathbf{Focus = (h, \frac{k+1}{4a})}[/tex]
[tex]\mathbf{Focus = (80, \frac{10+1}{4 \times -\frac{1}{640}})}[/tex]
[tex]\mathbf{Focus = (80, -\frac{11}{\frac{1}{160}})}[/tex]
[tex]\mathbf{Focus = (80, -11\times 160)}[/tex]
[tex]\mathbf{Focus = (80, -1760)}[/tex]
The equation of the directrix is:
[tex]\mathbf{y = -a}[/tex]
So, we have:
[tex]\mathbf{y = \frac{1}{640}}[/tex] ----- the directrix
The axis of symmetry is:
[tex]\mathbf{x = -\frac{b}{2a}}[/tex]
We have:
[tex]\mathbf{y = -\frac{1}{640}(x - 80)^2 + 10}[/tex]
Expand
[tex]\mathbf{y = -\frac{1}{640}(x^2 -160x + 6400) +10}[/tex]
Expand
[tex]\mathbf{y = -\frac{1}{640}x^2 +\frac{1}{4}x - 10 +10}[/tex]
[tex]\mathbf{y = -\frac{1}{640}x^2 +\frac{1}{4}x }[/tex]
A quadratic function is represented as:
[tex]\mathbf{y = ax^2 + bx + c}[/tex]
So, we have:
[tex]\mathbf{a = -\frac{1}{640}}[/tex]
[tex]\mathbf{b = \frac{1}{4}}[/tex]
Recall that:
[tex]\mathbf{x = -\frac{b}{2a}}[/tex]
So, we have:
[tex]\mathbf{x = -\frac{1/4}{2 \times -1/640}}[/tex]
[tex]\mathbf{x = \frac{1/4}{1/320}}[/tex]
This gives
[tex]\mathbf{x = \frac{320}{4}}[/tex]
[tex]\mathbf{x = 80}[/tex]
Hence, the axis of the symmetry of parabola is: [tex]\mathbf{x = 80}[/tex]

Solve for p
3(2p−1)−2(3p+4)=11p
Answer:
p = -1
Step-by-step explanation:
3(2p - 1) - 2*(3p+ 4) = 11p
Use distributive property: a(b +c) =a*b +a*c
3*2p -3*1 -2*3p + (-2)*4 = 11p
6p - 3 - 6p - 8 = 11p
6p - 6p - 3 - 8 = 11p
- 11 = 11 p
Divide both sides by 11
-11/11 = p
p = -1
