The vertex where the two triangles touch forms a pair of vertical angles, so that the angles on opposites sides of the vertex are congruent. You're shown that two legs of both triangles are congruent. All this tells you that the two triangles are isosceles, and furthermore that they are similar because of the congruence of their "base" angles.
This means
Answer:
8 and 10
Step-by-step explanation:
First, let's look at the factors of 80.
1 • 80 = 80
2 • 40 = 80
4 • 20 = 80
5 • 16 = 80
8 • 10 = 80
Look at each pair and evaluate their sum.
1 • 80 = 80
2 • 40 = 80
4 • 20 = 80
5 • 16 = 80
8 • 10 = 80
Our last pairing multiplies to 80 and adds up to 18. Therefore, your answer is 8 & 10.
Hope this helps!
Answer:
so 14 can go into 28, 2 times and 19 can go into 38 2 times so the techaer can make 2 group with 14 girls and 19 boys in each group.
Step-by-step explanation:
ANSWER
EXPLANATION
The given function is
When we plug in x=3 into this function, we obtain,
This means that the function is discontinuous at x=3.
We need to simplify the function to obtain,
This implies that,
The graph this function is a straight line that is continuous everywhere.
To graph
we draw the graph of
and leave a hole at x=3.
See diagram in attachment.
Hence the coordinates of hole is
Firstly, $3.99 × 5 = $19.95
Second, $2.75 × 5 = $13.75
Third, $2.70 × 3 = $8.1 (Since it is just $8.1 that won't make sense so we'd add a 0 so It's $8.10.)
Then we do the last one which is 13 × $0.89 = $11.57.
So now since we are done multiplying we can add it all up.
The answer is $53.37 when we finish adding it up.
and I don't know what A number sentence is sorry :(
I took a long time typing this :< I hope this helps though! :D
