Step-by-step explanation:

Answer: 30° and 110°

55° and 85°

70° and 70°

The sum of angles in a triangle is 180°. Therefore, since an angle has been given as 40°, the remaining angles will be:

= 180° - 40°

= 140°

Therefore,

30° + 110° = 140°

55° + 85° = 140°

70° + 70° = 140°

Answer:

-8

Step-by-step explanation:

-32^3/5

Fifth root of 32 is 2.

Thus, 2^3 is 8, but -8 instead due to making 32 positive

Hope this helps!

Answer:

8 hours

Step-by-step explanation:

First, you must subtract $32 from $125. You end up with $93.

Usually, you would do 93 divided by 12, but 93 is not a multiple of 12.

96, which is 12 times 8, is the closest to 93, so 8 hours is the correct answer.

W=130

Step-by-step explanation:

the question giving says_W=130and if minus is crossing to the other side it becomes+

12% is the percent decrease

95,920 is 88% of 109,000.
x/100 = 95,920/109,000

95,920 x 100 = 9,592,000

9,592,000 / 109,000 = 88

100 - 88 = 12

Since it is 88% of it, it decreased by 12%

Answer:

12%decrese

Step-by-step explanation:

percentage decrease=13080/109000 ×100

=12% decrease

The two right scalene triangles can be formed from the parallelogram B

A scalene triangle is a type of triangle with three different length sides and three interior angles that add up to 180 degrees. Scalene triangles have no equal of parallel sides , hence there is no line of symmetry. The interior angles of a scalene triangle can be acute , right or obtuse angles.

Given data ,

Let the parallelogram be represented as ABCD

Now , the figure ABCD represents a rectangle

So , the measures of angles ∠ABC = measure of angle ∠DCB = 90°

Let the diagonal of the rectangle be AC

The base of the rectangle = BC

The height of the rectangle = AB

So , the diagonal cuts the rectangle into two triangles each having different lengths and angles

And , the two triangles are ΔABC and ΔADC

Now , the triangles ΔABC and ΔADC are right scalene triangles

Hence , the triangles are scalene triangles

Answer:

Let's set up an equation;

12/100 * x = 16.5

where 12/100 is 12%

x is the number of the 12%

that would equal 16.5

So solve for x;

12/100 * x = 16.5

12/100x = 16.5

0.12x = 16.5

/0.12    /0.12

x = 137.5

Answer:

49 1/8

Step-by-step explanation:

92 8/9 - 43 5/6

Subtract the whole numbers

92 - 43 = 49

Find the LCD of 8/9 and 5/6 and rewrite to solve with the equivalent fractions.

16/18 − 15/18= 1/18

Combining the whole and fraction parts.

49 + 1/18 = 49 1/18

Answer:

49 1/18

Step-by-step explanation:

First, we can start off by rewriting our equation with parts separated.

92 - 43 + 8/9 - 5/6

Solve the whole numbers

92 - 43 = 49

Solve the fractions using LCD

8/9 - 5/6 = 1/18

Combine the whole and fractions

Answer:

x = e^12/100

Step-by-step explanation:

Solve for x over the real numbers:

10 ln(100 x) - 3 = 117

Add 3 to both sides:

10 ln(100 x) = 120

Divide both sides by 10:

ln(100 x) = 12

Cancel logarithms by taking exp of both sides:

100 x = e^12

Divide both sides by 100:

Answer:  x = e^12/100

Answer:

Kayla

Step-by-step explanation:

To find who spend the least amount of time on homework per hour, divide the number of hours by the amount of homework

Kayla: 3.2 ÷ 4 = 0.8

Karen: 5 ÷ 6 = 0.833

Since Kayla's number is lower, that means she spent fewer hours per homework than Karen. This means Karen spent the least amount of time in hours per homework.

Polynomials are expressions. The factorized form of the polynomial is 5x⁴-80 is 5(x⁴-16).

Polynomial is an expression that consists of indeterminates(variable) and coefficient, it involves mathematical operations such as addition, subtraction, multiplication, etc, and non-negative integer exponentials.

In order to factorize the given polynomial, we need to take the common terms out of the polynomial. Therefore, the polynomial can be written as

[tex]5x^4 - 80\\\\[/tex]

If we look at the polynomial the common term 5 can be taken out from both the terms, therefore,

[tex]5x^4 - 80\\\\= 5(x^4-16)[/tex]

Hence, the factorized form of the polynomial is 5x⁴-80 is 5(x⁴-16).
