What is the missing angle of a quadrilateral if the other three angles are: 40º, 100º and 120º?

Answers

Answer 1

Answer:

100

Step-by-step explanation:

Answer 2

Answer:

100°

Step-by-step explanation:

Angles in a quadrilateral add up to equal 360

That being said we can calculate the measure of the missing angle by subtracting the measures of the known angles from 360

So missing angle = 360 - 120 - 100 - 40

360 - 120 - 100 - 40 = 100

Hence, the measure of the missing angle is 100°

46.4 inch

Step-by-step explanation:

Area=l×b

93.6 =5.2×b

93.6/5.2 =b

So b= 18

p=2(18+5.2)

A 200 L tank of water is losing about 120 mL of water a day. If the tank starts off full, how long will it be before it is less than half full?

Answers

Answer: 834 days

Step-by-step explanation:

The tank will be half full when it has lost 100 L.

Convert that to milliliters so that it can be compared with the loss rate:

1 l = 1,000 ml

100 l = 100 * 1,000

= 100,000 ml

The rate of loss is 120 ml per day. To lose 100,000 ml, the leak would have to have been going on for:

= 100,000 / 120

= 833.3

= 834 days (less than half full)

no spam and kindly explain your answer!​

Answers

Answer:

(x + 1)(x + 2)(2x + 1)(x - 3).

Step-by-step explanation:

From the leading and last coefficients, 2 and -6  the values +/- 1, +/-2 , +/- 3 could be roots of this equation ( well, up to 4 of them).

Try x = 1:

f(1) = 2(1)^4 + 1^3 - 14(1)^2 - 19(1) - 6 = -36 so its not 1.

f(-1) = 2 - 1 - 14 + 19 - 6 = 0 do x = -1 is a root.

Therefore (x + 1) is a factor  (By the factor theorem)

Try x = 2:

f(2) =  32 + 8 -56 - 38 - 6 = -6o so x =2 not a root.

f(-2) = 32 - 8 - 56 + 38 - 6 = 0 so x = -2 is a root and (x + 2) is a factor.

(x + 1)(x + 2) = x^2 + 3x + 2.

Long division:

                        2x^2 - 5x - 3   <-----------Quotient

                      --------------------------------------------

x^2 + 3x + 2 )     2x^4  +   x^3   -14x^2 -  19x  -  6

                          2x^4  + 6x^3 +  4x^2  

                                      -5x^3  - 18x^2 - 19x

                                      -5x^3  - 15x^2 - 10x

                                                      -3x^2 - 9x  - 6

                                                      -3x^2  - 9x - 6

                                                       .......................

2x^2 - 5x - 3 = (2x + 1)(x - 3)

So Finally,   the factors are (x + 1)(x + 2)(2x + 1)(x - 3).

Solve the following quadratic function

Simplify your answer completely.
f(x) = 100 – 49x^2

Answers

Answer:

x = 10/7 or x = -10/7

Step-by-step explanation:

By using the completing the squares method, we have to divide the coefficient of the x term by 2, square it and add to both sides

From what we have here, the coefficient of the x term is 0

Thus, we have it that;

0 = 100 - 49x^2

We can proceed to use the difference of two squares here;

Whereby;

a^2 - b^2 = (a-b)(a + b)

0 = (10-7x)(10+7x)

10 - 7x = 0 or 10 + 7x = 0

7x = 10 or 7x = -10

x = 10/7 or x = -10/7

Step-by-step explanation:

[tex]n\ \%\ 25 = 2[/tex]

[tex]n <100[/tex]

Find n

[tex]n\ \%\ 2 = 1[/tex] implies that the number is odd and the possible solutions are:

The possible solutions to [tex]n\ \%\ 25 = 2[/tex] are:

1(-12,4)

2.(2,-12)

3.(7,0)

4.(7.5,2)

Answers

Answer:

Solution (4, -12)

None of the listed choices are a solution

Step-by-step explanation:

y = 4x - 28

y = 1.5x - 18

Set the equations equal since both equal y

4x - 28 = 1.5x - 18

Subtract 1.5x from both sides

2.5x - 28 = -18

Add 28 to both sides

2.5x = 10

Divide both sides by 2.5

x = 4

---------------------

use x= 4 in either equation

y = 4x - 28

y = 4(4) - 28

y = 16 - 28

y = -12

--------------------

Solution (4, -12)

PO.-4). Q15, 1)

Answers

Answer:

y = x-4

Step-by-step explanation:

The standard form is;

y = mx + b

where m is the slope and b is the y-intercept

we have the two points as (0,-4) and (5,1)

so we find the slope using the slope formula;

m = (y2-y1)/(x2-x1)

m = (1 + 4)/(5-0) = 5/5 = 1

The y-intercept value is the value of y when x = 0

We already have a point (0,-4) and the equation would be:

y = 1(x) + (-4)

y = x-4

Classify a triangle whose side lengths are 8, 16, and 18

A. Right Triangle

B. Acute Triangle

C. Obtuse Triangle

D. Isosceles Triangle

Answers

Answer:

Obtuse triangle

Step-by-step explanation:

A triangle is a polygon with three sides and three angles. There are different types of triangles such as right angled, acute, obtuse and isosceles triangle.

In right angle triangle, one angle is 90°. The square of the longest side (hypotenuse) is equal to the sum of the square of the two sides.

An acute triangle is a triangle with acute angles (less than 90°). The square of the longest side is less than the sum of the square of the two sides.

An obtuse triangle is a triangle with one obtuse angle (greater than 90°) and two acute angles (less than 90°). The square of the longest side is larger than the sum of the square of the two sides.

An isosceles triangle is a triangle with two equal sides.

Given a triangle whose side lengths are 8, 16, and 18, the longest side is 18.

Since no two sides are the same hence it is not an isosceles triangle.

Also, 18² > 16² + 8²; therefore this is an obtuse triangle
