Solve for x. (RIGHT ANSWER WILL GET BRAINLIEST)

Mathematics
1 answer:
puteri [66]3 years ago
7 0

Answer:

67

Step-by-step explanation:

The angle with x in it is a vertical angle to the other one labeled & the right angle put together.

Therefore:

48 + 90 = 2x + 4

Solve for x:

138 = 2x + 4

138 - 4 = 2x + (4-4)

134 = 2x

134/2 = 2x/2

X = 67

Hope this helps! Have a great day!

Hi , 7/16 times 4/3 times 1/2 equals to 28/96 because 7times4 times 1 equals to 28 and 16 times 3 times 2 equals to (28/96).The answer is also equivalent to 7/24.

A cable that weighs 6 lb/ft is used to lift 500 lb of coal up a mine shaft 400 ft deep. Find the work done. Show how to approxim
stealth61 [152]

Answer:

8.2 *10^5 ft lb

Step-by-step explanation:

Wcoal = 800*500  = 400000 = 4*10^5 ft lb

Wrope =\int\limits^{400}_0 {6(400-y)} \, dy

Using a right Riemann sum

The width of the entire region to be estimated = 400 - 0 = 400

Considering 8 equal subdivisions, then the width of each rectangular division is 400/8 = 50

F(x) = 6(400-y)

\left[\begin{array}{cccccccccc}x&0&50&100&150&200&250&300&350 &400\\f(x)&2400&2100&1800&1500&1200&900&600&300&0\end{array}\right]

Wrope = 50(2100) + 50(1800) + 50(1500) + 50(1200) + 50(900) + 50(600)

+ 50(300) + 50(0) = 420000 = 4.2 * 10^5 ft lb

Note: Riemann sum is an approximation, so may not give a accurate value

work done =  Wcoal + Wrope= 4*10^5+ 4.2 * 10^5 = 8.2 *10^5 ft lb
