Angle 2: 39.1°
⊝

Equation: 180 = 127.50 + 3.5x
Angle 1: 135.45°
Angle 2: 44.55°


Equation: 180 =

Answer:

No, because water temperature is confounded with brand of detergent.

Step-by-step explanation:

There is a very possible chance of allowing a third or confounding variable to have creepwd into the research. The aim was to investigate which of two detergents prevents color from fading. Hence, the test for both detergents should be carried out under the same research condition. However, with adoption of different water temperature for each of detergent A and B, there may be a relationship between fading and water temperature which is not what are trying to investigate. This difference in temperature will thus cause a spurious relationship in our research. Hence, water temperature has been confounded with detergent brand, making this experimental design a bad one.

From what I have learnt:

The number has an ending so it is rational

Irrational numbers don't end, e.g. π (3.1415926...)

Answer:

r = 105

Step-by-step explanation:

Given quadratic equation:

x² − 9x − 6

Quadratic formula is given by:

(-b ± √b² - 4ac) ÷ 2a

For the equation: x² - 9x - 6

a = 1, b = -9 and c = -6

Substitute in the quadratic formula:

(-b ± √b² - 4ac) ÷ 2a

(-(-9) ± √(-9)² - 4(1*-6)) ÷ 2*1

= 9 ± √105 / 2

The solution of x² − 9x − 6 is expressed as 9 plus or minus the square root of r, all over 2

Therefore, the value of r is 105

Answer:

1 Let x=1x=1.

2\times 1\times 4=8

2×1×4=8

2 Simplify  2\times 12×1  to  22.

2\times 4=8

2×4=8

3 Simplify  2\times 42×4  to  88.

8=8

8=8

Step-by-step explanation:

What is the Value of the expression 3 (2x - 4) when x = -3?​

2 Divide both sides by 88.

Given:

The graph of an inequality.

To find:

The inequality in slope intercept form.

Solution:

The slope intercept form is:

[tex]y=mx+b[/tex]

Where, m is slope and b is y-intercept.

From the given graph it is clear that the boundary line passes through the points (-3,0) and (0,-3).

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-0=\dfrac{-3-0}{0-(-3)}(x-(-3))[/tex]

[tex]y=\dfrac{-3}{3}(x+3)[/tex]

[tex]y=-1(x+3)[/tex]

[tex]y=-x-3[/tex]

From the given graph it is clear that the boundary line is a solid line and the shaded region lies above the line, so the sign of inequality must be "≥".

[tex]y\geq -x-3[/tex]

Therefore, the required inequality is [tex]y\geq -x-3[/tex].

Answer:

11:

since diagonal are equal of rectangle

QS=RT

4x+6=6x-4

6+4=6x-4x

2x=10

x=10/2

x=5

now

diagonal :4x+6=4*5+6=26

12.

again

QS=RT

9x+12=11x-10

12+10=11x-9x

2x=22

x=11

now

diagonal=9*11+12=99+12=111

Answer:

exact: V = 45pi in.^3

approximate: V = 141.4 in.^3

Step-by-step explanation:

V = (pi)r^2h

r = d/2 = 6 in./2 = 3 in.

V = (pi) * (3 in.)^2 * 5 in.

V = 45pi in.^3

V = 141.4 in.^3

Answer:

Solid A

Step-by-step explanation:

3 feet is 3 x 12 = 36 inches, which is less than 48 inches, so solid A has a larger surface area than solid B.

Answer:

Option A: {-2, 3, 1, 5}

Step-by-step explanation:

A function is a relationship that maps elements from one set (the domain, set of the inputs, the independent variables) into elements from another set (the range, set of the outputs, the dependent variables ).

Such that the standard notation is (x, y)

This says that the function/relation maps the element x into the element y.

So here the independent variable is x.

Now, in a relation:

{ (x₁, y₁), (x₂, y₂), ..., (xₙ, yₙ)}

The independent variable is represented with the set:

{x₁, x₂, ..., xₙ}

then, in the relation:

(–2, 4), (3, –2), (1, 0), (5, 5)

The set that represents the independent variable is a set with the first elements from each one of these four points:

{-2, 3, 1, 5}

The correct option is A.

Answer:

A= 306,87°

B= 196,26°

C= 112,62

Step-by-step explanation:

sinA =-4/5

A = -53,24°

A = 306,87°

tan B = 7/24

B = 16,26°

B = 196,26°

cos C = -5/13

C = 112,62°

Answer:

Assume that the two digits are x and y (x is at ones position and y is at tens position)

if we subtract the digit of a two digit number, we get 4.

this means,

x-y=4    ..................... (1)

if we interchange the digits of the number and subtract the new number from the original number we get 44.

this means,

old no. 10y+x

new no. 10x+y

10y+x-(10x+y)=44

10y+x-10x-y=44

9y-9x=44    ........................... (2)

solve the two equations:

id these two equations are solved, we get no solution.

meaning, such a number with these given conditions do not exist
