Answer:
0.5, 80%
Step-by-step explanation:
The length of CA is opposite of angle B and since the hypotenuse is known, you can write an equation like this: sin 40 = x/7 which simplifies to sin40 * 7 = x. The answer is A

❖ 7.255 to the nearest whole number is 7.
The numbers to the right of the decimal point are less than 500 so we round down. If the numbers were above 500, we would round up.

Answer:3x^2-5x+2=0
Step-by-step explanation:
Format of a quadratic equation= ax^2 +bx+c
Let x=1 and 2/3
When x=1
x-1=0.......(1)
When x=2/3
x-2/3=0.........(2)
Compare the equations
(x-1)(x-2/3)=0
x^2-2/3x-x+2/3=0
x^2-5/3x+2/3=0
Multiply all terms by 3
3x^2-5x+2=0
First, make the fractions both have common denominators, so 3/8= 9/24 and 5/12= 10/24. Then add them up and you get 19/24
