Let x=Don's present age
2x=Chris's present age
next year:
<span>x+1=Don's age
</span><span><span>2x+1=Chris's age
(x+1)+((2x+1)=4(x-1) (next year the sum of their ages will be four times as much as Don's age last year.)
x+1+2x+1=4x-4
x=6
2x=12
Don's present age=6
Chris's present age=12 </span><span>
</span></span>
Answer:
9
Step-by-step explanation:
Answer:
Volume is 48 yards cubed
surface area is 96 yards squared
An algebraic expression that represents the weight of the fruit that Pascal still has after feeding the birds is 26.7 - 1.7w.
The total pounds of fruit that Pascal has after feeding the birds can be determined by subtracting the sum of the pounds of fruits he sold and the pounds of fruits he uses to feed the birds from the total pounds of fruit he had at the beginning of the day.
Pounds of fruit left = pounds of fruit he had at the beginning of the day - (pounds of fruit he sold + pounds of fruits he used to feed the birds)
Pounds of fruit he sold = 5 x w = 5w pounds
Pounds of fruits he used to feed the birds = × = 53.3 - 3.3w
Pounds of fruit left = 80 - (5w + 53.3 - 3.3w)
After combining similar terms, the expression is:
26.7 - 1.7w

Given equation :
We know the formula,
can be written as
In the given problem angle theta is taken by x and fraction a/b is taken by 8.5/7.7.
In order to find the value of tan^-1(8.5/7.7), we need to put arc tan or tan^-1(8.5/7.7) in calculator.
By default, calculator would give angle in radians.
Also if you want answer in degrees, please do not forget to change the radian key(button) into degrees.
On putting tan^-1(8.5/7.7) in calculator, we get 0.834741.. radian approximately.
And in degrees it would be 47.827 degrees approximately.
