Write a congruence statement for the pair of triangles. Name the postulate or theorem that justifies your statement.

1 answer:

7 0

From the triangles, I think the congruence statement would be that of the ASA theorem. Triangle AWC is congruent to triangle RWC by virtue of the Angle-Side-Angle theorem. Hope this answers the question. Have a nice day.

Jin needs 0.8 gram of carbon for an experiment. She needs 4.15 times as much water. Jins says that she needs less than 4.15 gram

natima [27]

Answer:

That is a correct statement.

Step-by-step explanation:

This is because to find the appropriate amount, we would multiply the two numbers together. Since we are multiplying 4.15 by a number less than 1 (0.8), the number can only be lower. The number would only be higher if the number was greater than 1.

Solve these equation<br><br>4(3-x)=(1-2x)

serg [7]

To attempt this algebraic equation we will be multiplying 4 to (3 - x) bracket so as to form the term on L.H.S.

$:\implies\tt{4(3 - x) = (1 - 2x)}$

$:\implies\tt{(12 - 4x) = (1 - 2x)}$

$:\implies\tt{12 - 4x = 1 - 2x}$

Combining like terms, we get,

$:\implies\tt{12 - 1 = - 2x + 4x}$

$:\implies\tt{11 = 2x}$

$:\implies\tt{2x = 11}$

$:\implies\tt{x = \frac{11}{2} }$

$:\implies\tt{x = 5.5}$

The value of x is 5.5

Is the equation x=-5-y and 2+y=-x+3 coincident, intersecting, or parallel

Paha777 [63]

Well first, you have to get both equations to the y= form
y=mx+b

X=-5-y add y to x

y+x=-5 then subtract x

y=-x-5 is your equation
_____________________

for the second one:

2+y=-x+3 subtract 2

y=-x+1 is your equation
__________________________
Take both equations and compare:

Both the slopes are the same of -x, so that means the will lines never touch (also because of different y intercept)

So, the answer is parallel.

A-What fraction is shaded <br> B-what percentage is shaded

valkas [14]

Answer: A) 2/3 is shaded. B) 66.67% is shaded.

Step-by-step explanation:

The whole big triangle holds 9 total triangles in it.

Out of the 9 triangles 6 of them are shaded so the fraction will be 6/9 which reduces to 2/3.

Now convert 2/3 to a decimal to find what percentage is shaded.

2/3 = 0.6666...

0.6666 * 100 = 66.666..

66.666 as a percent is 66.67%
