Answer: C
Step-by-step explanation:
This is a 45-45-90 triangle. In a 45-45-90 triangle, the hypotenuse is x√2 in length. The legs are equal to each other. They have the length of x. X is consistent throughout all 3 sides of the triangle. Since we have the hypotenuse, we can set it equal to x√2 to find x that will let us know the length of the legs.
7√2=x√2 [divide both sides by √2]
x=7
Now that we know the length is x=7, the legs are 7 in length each.
Answer:
B
Step-by-step explanation:
We can subtract the fixed 12 of 40 to see how much she can spend on messages alone. So we are left with $28.
At 10 cents apiece for every dollar she can send 10. So we would get 280 messages.
I dont understand the options given, I think there are equation signs missing
So it would be B I assume since x=280
Answer:
-8/6 is equivalent to the -8.(1/6).
Answer:
David gets £34, Egil gets £119 and Frances gets £153.
Step-by-step explanation:
Let the amount of money David gets be 2x, Egil be 7x and Frances be 9x.
7x = 2x + 85
7x - 2x = 85
5x = 85
x = 85 ÷ 5
x = 17
David (2x) = 2 × £17
= £34
Egil (7x) = 7 × £17
= £119
Frances (9x) = 9 × £17
= £153
