Answer:
x = -4
Step-by-step explanation:
6 -x = 5x + 30
6 - 30 = 5x + x
-24 = 6x
divide both sides by 6 to get x = -4
Answer:

Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
m(x) = 2(x + 4)² - 8 ← is in vertex form
with vertex = (- 4, - 8 ) → A
if I'm 2 lessons into a class and my progress bar says that I am 1/3 of the way complete. How many lessons are in the class?
Answer:
Well you have 6 lessons in total.
Step-by-step explanation:
if you finished 2 lessons you are 1/3
It is basically the same as 2/6 lessons
so
2/6 = 1/3
You have 6 lessons

A rectangle has sides of 4 and 6 units. Which expression could you use to find the volume (in
cubic units) of the three-dimensional object formed by continuously rotating the rectangle about
the shorter side?
Answer:
144π
Step-by-step explanation:
If the rectangle below is continuously rotated about side, the solid figure formed is a cylinder.
A rectangle with sides of 4 and 6 unit continuously rotated about the shorter side gives a cylinder with a radius (r) of 6 units and a height (h) of 4 units. The volume of a cylinder is given by:
Volume = πr²h
Volume = π × 6² × 4 = 144π
The volume of the cylinder formed is 144π
a car travels at 54 km/h for first 20seconds , 36km/h for next 30seconds and finally 18km/h for next 10 seconds find the averade velocity
Answer:
39 km/h
Step-by-step explanation:
Velocity is the rate of change of distance in a given direction with time. Mathematically,
Velocity = Displacement/time
Like speed, velocity is measured in Km/h or m/s.
Given that the car travels at 54 km/h for first 20seconds,
since 60 seconds = 1 minute and
60 minutes = 1 h,
20 seconds
= 20/(60 ×60) h
= 1/180 h
In the same vein,
30 seconds
= 30 / (60 ×60) h
= 1/120 h
10 seconds
= 10/(60 ×60) h
= 1/360 h
Hence if the car travels 54 km/h for 10 seconds, the distance covered
= 54 × 1/180
= 3/10 Km
If the car travels 36km/h for next 30seconds, the distance covered
= 36 × 1/120
= 3/10 Km
If the car travels 18km/h for next 10 seconds, the distance covered
= 18 × 1/360
= 1/20 km
Total distance = 3/10 Km + 3/10 Km + 1/20 Km
= 13/20 Km
Total time spent = 20 + 30 + 10
= 60 seconds
= 1/60 h
Average velocity = 13/20 km/ 1/60 h
= 39 Km/h

Mia throws two fair dice together. What is the probability of scoring exactly one 6? The table below shows the 36 mutually exclusive outcomes when two fair dice are thrown.
i'll give brainliest if you answer correctly ;))
1.5/18
2.5/36
3.11/36
Answer:
5/18
Step-by-step explanation:
If we count all of the outcomes in the table with exactly one 6 in it, we will see that there are 10 outcomes that do so, and this is out of 36, so the probability will be 10/36 or 5/18.

Answer:
A = 5/6
Step-by-step explanation:
The line is given by
Ax - 4y = 1
We have a point on the line
(6,1)
Replace x with 6 and y with 1
A(6) - 4(1) = 1
6A -4 = 1
Add 4 to each side
6A -4+4 = 1+4
6A = 5
Divide each side by 6
6A /6 = 5/6
A = 5/6

Answer:
a) 125 ml of milk
b) 7.5 g of butter
Step-by-step explanation:
Answer: A. Simon needs 125 ml of milk to make 4 pancake. B. He needs 7 and a half grams of butter to make 12 pancakes
Step-by-step explanation:
A) If we know that 250 ml milk can help make 8 pancakes then we could set up a proportion as to how many milk we need to make 4 pancakes.
[tex]\frac{250}{8} = \frac{x}{4}[/tex] Solve by cross product,
8x = 1000
x = 125
B) The same with this we could also set up a proportion. We know you need 5 grams of butter when making 8 pancakes.
[tex]\frac{5}{8} = \frac{x}{12}[/tex] solve by cross product
60 = 8x
x = 7.5
