2/13 × 26 2/5 = ??

To do this, we have to take the second fraction, and turn it into a mixed number.

To do so, we have to multiply the denominator (bottom number) with the whole number, and then add that with the numerator (top number).

26 2/5= (5 × 26) + 2 = (130) + 2 = 132/5

Now, we do 2/13 × 132/5

Multiply the top numbers together, and then multiply the bottom numbers together.

Now, you have 264/65

You have to make this a mixed number, by seeing how many times (64) goes into (264).

(64) goes into 264 four times, with a remainder of 4, so now, your answer is: 

4 4/65

If angle x=55% and angle y=35, calculate the following 1.cos(x+y) ​
Setler79 [48]

Answer:

cos(X+Y) = cos(55+35) = cos(90) = 0

Step-by-step explanation:

cos(X+Y) = cosXcosY - sinXsinY

cos(55+35) = cos(55)cos(35) - sin(55)sin(35)

cos(55+35) = cos(55)cos(35) - cos(90-55)cos(90-35)

cos(55+35) = cos(55)cos(35) - cos(35)cos(55)

cos(55+35) = 0

cos(90) = 0

The length of a rectangle is 1 inch less than twice the width. the area is 21 inches^2 what is the length?
ale4655 [162]
Hi.

Formula for area: A = 2l + 2w, where l is the length and w is the width.

Given information:
• l = 2w - 1
• A = 21 in^2

We can plug in our values accordingly and solve for w.

A = 2l + 2w
21 = 2(2w - 1) + 2w
21 = 4w - 2 + 2w
23 = 6w - 2
23 = 6w
3.83 = w

Plug 3.83 for w into 2w - 1 to find length.

2(3.83) - 1
7.66 - 1
6.66

Finally, check your work by plugging your values into the original equation.

21 = 2(6.66) + 2(3.83)
21 = 13.32 + 7.66
21 = 20.98

Answer:
The length is approximately 6.66 inches.
