The car is travelling at 90 kilometers per hour (90 kmph)
What is the car's speed in kilometers per minute?)
We know 1 hour = 60 minutes,
90 km / 60 minutes = 1.5 kilometers per minute
<em>The speed of the car is 1.5 kilometers per minute
</em>
How many kilometers will the car travel in 15 minutes?)
We know that the car travels 1.5 kilometers in 1 minute. So in 15 minutes:
1.5 kilometers * 15 minutes = 22.5 kilometers
The car will travel 22.5 kilometers in 15 minutes.
Answer:
m1 = 62.5
m2 = 62.5
m3 = 55°
m4 = 75°
m5 = 50°
Step-by-step explanation:
m1: Sides 1 and 2 are congruent so angle will be the exact same as m2:
180° - 55° = 125 | 125 / 2 = <u>62.5°</u>
m2: same as m1; <u>62.5°</u>
m3: equivalent to <u>55°</u> due to its location
m4: angle of a line is 180° so 180° - 105° = <u>75°</u>
m5: angles of triangle add to 180° so 180° - (75° + 55°) = <u>50°</u>
Answer:
(0,3) and (1,4) are solution sets of given system
Step-by-step explanation:
Given that:
y= 3x^2−2x+3 ------------- eqA
y = x + 3 ------------------ eqB
Putting value of y from eqB to eqA
x + 3 = 3x^2−2x+3
Taking all variables to left side:
Signs pf transferred terms will be changed
3x^2−2x+3 - x - 3 = 0
Adding like terms we get:
3x^2−3x = 0
Dividing both sides by 3 we get:
x^2 - x = 0
Now take x common:
x(x-1)= 0
So
x = 0 and x = 1
Now put value in eqB
y = 0 + 3 and y= 1 + 3
we get:
y = 3 and y = 4
So solution sets are:
(0,3) and (1,4)
