Answer:
We use ratio and proportion
If EC$ 2.50 = US$ 1.00
Then EC$ 20.00 = US$ 20 × 1 / 2.50
= US$ 8.00

Answer:
5/9
Step-by-step explanation:
The area of one triangle is ...
A = 1/2(x)(2x) = x²
Then the area of the four triangles is ...
unshaded area = 4(x²)
The length of DC is 2x+x = 3x, so the area of ABCD is ...
total area = (3x)² = 9x²
Then the fraction that is shaded is ...
(9x² -4x²)/(9x²) = 5/9
5/9 of the area of ABCD is shaded.
Answer:
0.9 × 81 is greater
Step-by-step explanation:
Since one of the factors is the same in both problems, and all numbers are positive, the greatest result will obtain from the problem with the largest factor that is different.
0.90 > 0.75 ... so the product 0.90 × 81 is greater than 0.75 × 81
The answer would be A. The triangle with the 70 seems to be isosceles and that means that two of the angles equal 70. 70+70=140. Subtract 140 from 180 to find the third angle because every triangle has a total of 180 degrees. Due to the fact that x and the 40 degrees are on the same line, they will equal 180 degrees. So, 180-40=140. X=140. I hope this helps
Half of the numbers on the cube are even, so there's a 1/2 chance that that number is even. 3/5 of the numbers on the cards, however, are odd. The chance that both of these occur is 3/5*1/2=3/10.
