What is 3/4 = w + 2/5

shusha [124]

Convert all fractions to have the same denominator.

To convert, we must find the least common multiple of the two denominators of the fractions:

Multiples of 4: {4,8,12,16,20}
Multiples of 5: {5,10,15,20}

The least common multiple of 4 and 5 is 20.

Multiply the fractions by a number that will result in the denominator being 20:

$\frac{3}{4} * \frac{5}{5} = \frac{15}{20}$

$\frac{2}{5} * \frac{4}{4} = \frac{8}{20}$

The equation should now look like this:

$\frac{15}{20} = w + \frac{8}{20}$

Subtract both sides by 8/20 to get w by itself:

$\frac{15}{20} - \frac{8}{20} = \frac{7}{20}$

$w = \frac{7}{20}$

The value of w is 7/20.

Solve for x. Round to the nearest tenth, if necessary.

Sphinxa [80]

Answer:

2.8

Step-by-step explanation:

tan = opposite / adjacent

( opposite = side opposite of the angle and adjacent = side length that is not the opposite nor the hypotenuse ( longest side ) )

we are given an angle, ∠E = 26°

tanE = x / 5.7

tan26 = x / 5.7

==> multiply both sides by 5.7

5.7tan26 = x

==> simplify

x = 2.8 ( rounded )

For a snack, sander ate a plum with 32 calories and several strawberries with 4 calories each. If the total number of calories i

muminat

Answer:

6 strawberries

You subtract 32 from 56, which gives you 24. Then, if one strawberry is 4 calories, you can eat 6 of them to gain 24 calories.

32 + 24 = 56 ... So one plum (32) and six strawberries (4+4+4+4+4+4) gives you 56 calories, which is the total. That's how you can check your work.

If the farmer has 250 feet of fencing to create a rectangular pen, define a function f that expresses the area of the field (mea

hoa [83]

Answer:

Maximum area possible

f(max) = 3906,25 ft²

Dimensions:

a = 62,5 ft

w = 62,5 ft

Step-by-step explanation:

Perimeter of the rectangular fencing P = 250 feet

And sides of the rectangle a and w (width of rectangle)

Then

A = a*w

2a + 2w = 250 ⇒ a = (250 -2w)/ 2 ⇒ a = 125 - w

f(w) = (125 - w ) *w f(w) = 125w - w²

Taking derivatives both sides of the equation

f´(w) = 125 - 2w f´(w) = 0 125 - 2w = 0

w = 125/2

w = 62,5 ft ⇒ a = 125 - 62,5

a = 62,5 ft

f(max) = ( 62,5)²

f(max) = 3906,25 ft²
