X = 3y
/3 /3
y = 3x
the answer is y = 3x
Answer: 340 in. squared
Step-by-step explanation:
17*7=119
15*7=105
8*7=56
8/2*15=60
119+105+56+60=340 in.^2
Answer:
3x^2y

Answer:
750 rupees is used to make shirt
250 rupees is profit
Step-by-step explanation:
If the retailer sold the shirt for 1000 rupees and got 25% profit then that means 1/4 is profit and 3/4 is how much the retailer spent to make the shirt.
So 1000 times 3/4 is 750 which is how much the shirt really cost and
1000 times 1/4 is 250 and that is the retailers profit.
Area of a triangle = (1/2)*base*height
For both of the triangles, you have the base (8.8 for the triangle on the left, 7.6 for the triangle on the right) and the side lengths, but not the height. But since both are isosceles triangles, you can find the height using the pythagorean theorem.
5.
First divide the triangle vertically into two triangles (see attached picture). Now you have two right triangles, you can apply the pythagorean theorem on either one of them to find the height. The pythagorean theorem says that for a right triangle, , where c is the hypotenuse and a and b are the sides of the triangle.
Substituting the given values and rounding to nearest tenth:
Now that you have the height, you can find the area of the entire triangle.
A = (1/2)*base*height
A = (1/2)*8.8*9.0 = 39.6
6.
Same procedure.
A = (1/2)*base*height
A = (1/2)*7.6*9.2 = 35.0
