Answer:

$\displaystyle m\angle JKM = 50$

Step-by-step explanation:

remember that,

if a side of a triangle expanded exterior so formed is equal to the sum of the two interior angles

so,

$\displaystyle m\angle JKM = 25 + 25$

simplify addition:

$\displaystyle m\angle JKM = 50$

Need help with 73, 74, 75, & 76. Find the value of X.

bija089 [108]

Answer:

see explanation

Step-by-step explanation:

73.

18 = 3x $\sqrt{3}$ (divide both sides by 3 )

6 = x $\sqrt{3}$ ( multiply both sides by $\sqrt{3}$ )

6 $\sqrt{3}$ = 3x [ $\sqrt{3}$ × $\sqrt{3}$ = 3 ]

divide both sides by 3

x = 2 $\sqrt{3}$

74.

24 = 2x $\sqrt{2}$ ( divide both sides by 2 )

12 = x $\sqrt{2}$ ( multiply both sides by $\sqrt{2}$ )

12 $\sqrt{2}$ = 2x ( divide both sides by 2 )

x = 6 $\sqrt{2}$

75.

9 $\sqrt{2}$ × x = 18 $\sqrt{2}$ ( divide both sides by 9 $\sqrt{2}$ )

x = 2

76.

2 = x × $\frac{4}{\sqrt{3} }$ ( multiply both sides by $\sqrt{3}$ )

2 $\sqrt{3}$ = 4x ( divide both sides by 4 )

x = $\frac{\sqrt{3} }{2}$

daser333 [38]

Answer: The answer is A

Step-by-step explanation: When you add 1/2+1/5+1/3 it equals 31/30 which when converted is equal to 1.033 which is less than 1 1/2.

Answer:

A)2

Step-by-step explanation:

we would like to integrate the following definite Integral:

$\displaystyle \int_{0} ^{1} 5x \sqrt{x} dx$

use constant integration rule which yields:

$\displaystyle 5\int_{0} ^{1} x \sqrt{x} dx$

notice that we can rewrite √x using Law of exponent therefore we obtain:

$\displaystyle 5\int_{0} ^{1} x \cdot {x}^{1/2} dx$

once again use law of exponent which yields:

$\displaystyle 5\int_{0} ^{1} {x}^{ \frac{3}{2} } dx$

use exponent integration rule which yields;

$\displaystyle 5 \left( \frac{{x}^{ \frac{3}{2} + 1 } }{ \frac{3}{2} + 1} \right) \bigg| _{0} ^{1}$

simplify which yields:

$\displaystyle 2 {x}^{2} \sqrt{x} \bigg| _{0} ^{1}$

recall fundamental theorem:

$\displaystyle 2 ( {1}^{2}) (\sqrt{1} ) - 2( {0}^{2} )( \sqrt{0)}$

simplify:

$\displaystyle 2$

hence

our answer is A

the width of a rectangle is 12 cm less than the length the perimeter is 156 cm. Find the with and length

mamaluj [8]

We know that the perimeter of a rectangle is twice the length, plus twice the width.

P = 2L + 2W

We also know that the perimeter is 156.

P = 156

Finally, we know that the width is 12 less than the length.

W = L - 12.

The next thing that we do is substitute the information that we have into the original equation:

P = 2L + 2W

156 = 2L + 2(L - 12)

From this point we start to solve

156 = 2L + 2L - 24 <---we multiplied the '2' through the parenthesis

156 + 24 = 2L + 2L - 24 + 24

180 = 2L + 2L <--- getting like terms on same sides

180 = 4L <---combining like terms

180/4 = 4L/4 <--- getting like terms on same sides

45 = L <---now we have a value for L

Now we take the known value for L and substitute it in to our equation for W

W = L - 12

W = 45 - 12

W = 33

So now we have Length = 45 and Width = 33.
