Answer:-8/6=y

Step-by-step explanation:

You have to do KCF which means keep the number on the left or right left in this case, change the mark to a multiplication symbol, and then flip the other fraction which means 3/8 will be 8/3 and if you are looking for a mixed fraction asnwer would be -1 1/3 pls mark as brainliest if right

Are the two triangles similar?

Tpy6a [65]

Answer:

Option B Yes by AAA

Step-by-step explanation:

we know that

If the two triangles are similar, then the ratio of its corresponding sides is equal and its corresponding angles are congruent

$\frac{HM}{MK}=\frac{GM}{MJ}$

substitute the values and verify

$\frac{8}{12}=\frac{6}{9}$

simplify

$\frac{2}{3}=\frac{2}{3}$ -------> is true

therefore

The triangles are similar by AAA------> the three angles are congruent

Find the value of r so the line that passes through each pair of points has the given slope.

ZanzabumX [31]

M = (y2 - y1) / (x2 - x1)
1/4 = (5-3) / (r +4)
1/4 = 2/ (r + 4)
Cross multiply
2*4 = r + 4
8 = r + 4
Subtract 4 from both sides
4 = r

CHECK
(-4,3)(4,5)
m = (5-3)/(4--4) = 2/8 = 1/4

Find the total surface area of the net below.

Solnce55 [7]

Total surface area of the triangular prism is 81.6 square m.

Step-by-step explanation:

b = 3 m

h = 2.6 m

p = 3+ 2.6 +2.6= 8.2

H = 9 m

SA = bh + pH

= 3 × 2.6 + 8.2 ×9

= 7.8 + 73.8

= 81.6

Therefore,

SA = 81.6 square m

Total surface area of the triangular prism is 81.6 square m.
