Two cars A and B 250 km apart are traveling towards each other on the same road. Car A travels at 55 km/h
while car B travels at 70 km/h.
(a) When will they meet on the road?
(b) Find the distance each car travels before they meet.
Answer:
At 2 hours they will meet on the road
Car A: 110 km; Car B: 140 km
Step-by-step explanation:
Since the total distance is 250 km, we know that when the sum of the miles driven by each car adds to 250, they will meet.
Let x be the time, in hours.
Miles Travelled
Car A (55km/h)x
Car B (70 km/h)x
(55km/h)x + (70 km/h)x = 250
55x + 70x = 250
125x = 250
x = 2 hours At 2 hours they will meet on the road
Distance Travelled
Car A (55km/h)2 = 110 km
Car B (70 km/h)2 = 140 km

List all congruent angles and write a proportion that relates the corresponding side
Proportion of corresponding side is FH/JH = HG/HK = FG/JK.
What are congruent triangles?Congruent triangles are triangles that are the same size and shape in every way. The sign for congruent is ≅ . Two triangles are considered to be congruent if the measurements of one triangle's three sides and three angles are the same as those of another triangle's sides and three angles.
Given triangles are similar ΔFGH ∼ ΔJKH
We can make the angles of this statement that correspond to each other congruent. We can then write a proportion that relates the corresponding sides to one another because the sides of similar triangles are proportional to one another.
so angles ∠GFH ≅ KJH; ∠GHF ≅ ∠KHJ; ∠HFG ≅ ∠HJK
and proportion of corresponding side is FH/JH = HG/HK = FG/JK.
Hence the proportion that relates the corresponding side are FH/JH = HG/HK = FG/JK.

A horse's mane grows at the rate of 6 over 5 centimeters per month.
How many months will it take the horse's mane to grow 24 over 10 centimeters?
Explain your answer using words, and show your work using division of fractions.
Answer:
It will take 2 months for the' mane to grow 24/10 centimeters, because 24/10 divided by 6/5 = 24/10 x 5/6 would be 2 months.
Step-by-step explanation:
Hope this helps, have a good day/night :)
It will take 4/2 months or 2 months for the horse's mane to grow 24/10 centimeters.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
A horse's mane grows at the rate of 6 over 5 centimeters per month.
Let x be a number of months.
(6/5)x = 24/10
6x = 12
x = 12/6 = 4/2 or
x = 2 months
Thus, it will take 4/2 months or 2 months for the horse's mane to grow 24/10 centimeters.

given f (x) = 2x - 10 forwhichvalueofxthat f (x) = -12
Answer:
=-240..................
Answer:
x = - 1
Step-by-step explanation:
f(x) = 2x - 10 and f(x) = - 12, then equating gives
2x - 10 = - 12 ( add 10 to both sides )
2x = - 2 ( divide both sides by 2 )
x = - 1

Answer:
An Ojibwe event in which women of all ages run, bike and canoe.
Step-by-step explanation:
A and B are complementary angles. If A = (x – 23)° and m
B = (2x + 29)°, then find the measure of B.
Answer:
∠ B = 85°
Step-by-step explanation:
Complementary angles sum to 90° , then
x - 23 + 2x + 29 = 90 , that is
3x + 6 = 90 ( subtract 6 from both sides )
3x = 84 ( divide both sides by 3 )
x = 28
Then
∠ B = 2x + 29 = 2(28) + 29 = 56 + 29 = 85°
