So, this is a rate problem, so the forumla we would get is
2.5g=30
(Note this is not one of the choices), so if we look, there is an equivelent equation.
If we divide both sides by g we get
2.5=30/g
B is the correct answer
Answer:
9+9
Step-by-step explanation:
9+9=18
23-5=18
Answer:
Yes
Step-by-step explanation:
The formula for area of a triangle is A = (1/2)bh,
For the first triangle we can leave it in general terms, so it's area is
A = (1/2)bh, depending on what b and h are, but it doesn't matter here...
The second triangle has base that is twice the other triangles base. Bases being multiples of each other is the definition of being proportional so the bases are proportional, an the area of the second triangle is
A = (1/2)(2b)h, which simplifies to
A = bh
Comparing the 2 areas, you can see that one has a multiplier of (1/2), so their areas are proportional
Answer:
No
Step-by-step explanation:
<u>Given </u><u>:</u><u>-</u><u> </u>
- A triangle with some side measure .
- The sides are 4 ,6,7.
And we need to tell whether it is a right angled triangle or not . It will be a right angled triangle if it follows the Pythagoras Theorem.
<u>Pythagoras</u><u> Theorem</u><u> </u><u>:</u><u>-</u><u> </u>
- In right angle triangle the sum of squares of the two smallest sides is equal to the square of the largest side .
Here the two smallest sides are 4 & 6 .
<u>Sum </u><u>of </u><u>Squares </u><u>of </u><u>4</u><u> </u><u>and </u><u>6</u><u> </u><u>:</u><u>-</u><u> </u>
4² + 6²
24 + 36
60
<u>Square</u><u> </u><u>of </u><u>7</u><u> </u><u>:</u><u>-</u><u> </u>
7²
49
<u>And </u><u>:</u><u>-</u><u> </u>
- They aren't equal. So the triangle is not a right angled triangle .
<u>Hence </u><u>the triangle is not a right angle triangle</u><u>.</u>
Remark
Just to make 2 answers possible, I will add how I think this problem should be done. Start with the lone tile on the right. There is only 1 tile in that group. Make a table
Table
Number in 1 group Name Groups Total
1 units 1 1 * 1 = 1
10 tens 3 3 * 10 = 30
10*10 = 100 hundreds 4 4 *100 = <u>400</u>
Total 431
The answer is 431
