Answer:
18 km/h
Step-by-step explanation:
1. Convert 175 metres into km
1000 m = 1 km (divide by 1000)
175 ÷ 1000 = 0.175 km
so 175 m = 0.175 km
2. Convert 35 seconds into hours
60 seconds = 1 min
60 mins = 1 hour
3600 (60 × 60) seconds = 1 hour (divide by 3600)
35 ÷ 3600 = 0.00972...
3. Calculate the speed
speed = distance ÷ time
= 0.175 ÷ 0.00972...
= 18 km/h

There are only red beads and green beads in a bag.
The ratio of the number of red beads to the number of green beads is 5:9
(a) What fraction of the beads are red?
Answer:
Assume there are 5x red beads and 9x green beads
Total no. of beads = 5x+9x = 14x
Fraction of beads that are red = 5x out of 14x
or 5/14

Kareem wanted to write an equation for his friend that has many solutions. Help him write an equation.
Answer: (x+2)*(x-4)*(x+21) = 0 has "many" solutions
Step-by-step explanation: (x+2) = 0 only has one solution.
(x+2)*(x-4) = 0 has two solutions, -2 and 4
(x+2)*(x-4)*(x+21) = 0 has three solutions, -2, 4, and -21, etc
If "many" means more than three, then add another (x+XX) term. A quadratic equation generally has two solutions.

Given the points (0, -1) and (6, 1), we need the following information to solve for the equation of the line:
We need the slope and the y-intercept.
Let (x1, y1) = (0, -1)
(x2, y2) = (6, 1)
Substitute these values into the following slope formula:
[tex]m = \frac{y2 - y1}{x2 - x1} = \frac{1 - (-1)}{6 - 0} = \frac{1 + 1}{6} = \frac{2}{6} = \frac{1}{3}[/tex]
Therefore, the slope (m) = 1/3.
Next, we need the y-intercept, (b), which is the point on the graph where it crosses the y-axis. It is also the value of the y-coordinate when its corresponding x-coordinate = 0.
Looking at one of the given points, (0, -1), this represents the y-intercept. Therefore, the y-intercept (b) = -1.
Now that we have our slope, m = 1/3, and y-intercept, b = -1, we can write our linear equation in slope-intercept form as:
y = 1/3x - 1

Original: $99.99
New: _________
Tax: 8.75
%Discount: 40%
Answer:
$68.74
Step-by-step explanation:
Original: $99.99
New: x
Tax: $8.75
Discount : 40%
Discounts are applied before tax.
40% of 99.99 = 0.40(99.99) = 39.996
99.99 - 39.996 = 59.994
Apply tax:
59.994 + 8.75 = 68.744 ≈ 68.74

I've done the work but I need to know what my new coordinates will be
Here's the question
Use the mapping (x+3, y-5), for the transformation of triangle ABC with vertices A(-2, -4), B(0, 0), and C(1, -3), find the coordinates of the new triangle A’B’C’ . You must show all your work.
And then here is the answer
You’re going to go left side three points and down five for every point on the graph (ABC) and once you do that label the ABC marks with an apostrophe like so; A’B’C’ for every time you change places

Rewrite the following equation in slope-intercept form. Y + 4=1/3(x-6)
Answer:
[tex]y=\dfrac{1}{3}x-6[/tex]
Step-by-step explanation:
Slope intercept form: y = mx + b
[tex]y + 4 = \dfrac{1}{3}(x -6)\\\\y + 4 = \dfrac{1}{3}x - \dfrac{1}{3}*6\\\\y + 4 =\dfrac{1}{3}x - 2\\\\y = \dfrac{1}{3}x - 2 - 4\\\\y =\dfrac{1}{3}x - 6[/tex]
p/q=r/s (solve for q)
Answer:
q=pr/s
Step-by-step explanation:
p/q=r/s multiplication is the inverse of division so they cancel out. and you have to do the same thing to both sides so multiply both sides by "q" it cancels out on the left and stays on the right leaving you with
q=pr/s

q = 4p + 14
q = 4p - 2
q = 4p + 2
Answer:
q=4p-14
Step-by-step explanation:
> 5q-4q+6=4q-8
> 5q-4q+6+8=4p
> q+14=4p
