Answer:

215.4

Step-by-step explanation:

first u do 223.4 - 221.8 to find how much we losses a week which is 1.6 then u do 218.6 - 1.6 = 217 (week 5) then 217 - 1.6 = 215.4 (week 6)

Answer:

y = -x - 2

Step-by-step explanation:

y = x +  2        {Compare with y = mx + c}

Slope = m1 = 1

Slope of the line S = m2 = -1/m1 = -1/1 = -1

(-6 , 4)

y -y1 = m (x -x1)

y - 4 = (-1)(x - [-6] )

y -4 = (-1)(x + 6)

y -4 = (-1)*x + (-1) *6

y - 4 = -x - 6

     y = -x - 6 + 4

    y = -x - 2

the correct answers are 3, 4 and 5

Answer:

[tex] x = - \frac{2}{9} [/tex]

Step-by-step explanation:

Since, the geometric mean of x+3 and 4x+1 is 2x+1.

Therefore, by geometric mean theorem:

[tex] {(2x + 1)}^{2} = (x + 3)(4x + 1) \\ \\ \cancel{4 {x}^{2}} + 4x + 1 = \cancel{4 {x}^{2}} + x + 12x + 3 \\ \\ 4x + 1 = 13x + 3 \\ \\ 4x - 13x = 3 - 1 \\ \\ - 9x = 2 \\ \\ x = - \frac{2}{9} [/tex]

Hello There!

So first things first

we need to find the measure of ∠ABD

If you didn´t know the sum of the triangle angles is 180

so to find ∠ABD we subtract the given angles ( 30 and 25) from 180

180-25-30=125

so angle ∠125

Now lets find ∠DBC

∠ABD and ∠ DBC are supplementary angles so the sum of the two angles is 180

So to find ∠DBC we subtract 125 from 180

180-125=55

so ∠DBC = 55

Now we can find the measure of ∠BDC

remember like stated before the sum of all of the angles in a triangle is 180

So to find the measure of ∠BDC we subtract the given angles from 180

180-90-55=35

so we could conclude that ∠BDC = 35

Other ways to solve for ∠DBC:

angle DBC is an exterior angle of ΔABD

the measure of an exterior angle is equal to the sum of the opposite interior angles

so basically ∠DBC = ∠ADB + ∠BAD

30+25=55 so ∠DBC = 55

Other ways to find angle BDC:

Having found the measure of ∠DBA and the other opposite angle we could find ∠BDC

Like stated before the measure of an exterior angle is equal to the sum of the opposite interior angles

basically ∠DBA = ∠BDC + ∠BCA

we have the measures of ∠BCA and ∠DBA so we plug in the values

125=∠BDC+90

isolate the variable by subtracting each side by 90

125-90=35

we´re left with

∠BDC=35

I hope this helps and if you have anymore questions, feel free to ask! :)

ANSWER:

(x,y) = (5,-1)

Answer:

(5, -1)

Step-by-step explanation:

Solve the system of equations by elimination.

4x + 3y = 17

3x + 2y = 13

Multiply the top equation by -3 and the bottom equation by 4:

-12x - 9y = -51

12x + 8y = 52

Add these together:

-y = 1

y = -1

Plug in -1 as y into one of the equations, and solve for x:

4x + 3y = 17

4x + 3(-1) = 17

4x - 3 = 17

4x = 20

x = 5

So, the solution is (5, -1)

Answer:

-13

Step-by-step explanation:

Well, they do most of the work for you all you have to figure out is what is "1/5(-65)". To do this you have to turn 1/5 into a decimal so 1 divided by 5 which equals 0.2 then multiply that by -65. That will give you your simplified answer of -13.

Answer:

Step-by-step explanation:

each of the 6 number has a 1/6 chance of being rolled

 1       2       3      4      5       6

1/6     1/6    1/6    1/6    1/6    1/6

Every time the cube is rolled  there is a 6/6 chance of any number comes up

1/6  +   1/6  +  1/6 +   1/6 +   1/6  +  1/6   = 6/6     or  1  

What is the probability of NOT rolling a 2? Any other number

 1        2       3        4        5         6

1/6  +   0  +  1/6 +   1/6  +  1/6 +   1/6   =   5/6    or    0.8333

0.03 x 0.6

= (3 x 6) / 1000

= 18 / 1000

0.018

Answer:

[tex]x=\frac{\sqrt{2}}{2}[/tex]

Step-by-step explanation:

The given triangle is an isosceles right triangle, meaning that the 45-45-90 triangle side rule applies. The 45-45-90 triangle side rule states that the two legs (sides that are adjacent to the right angle) are congruent, and the hypotenuse (the side opposite the rights angle) is equal to the leg times the square root of two. Using this property, one knows that the leg is equal to the hypotenuse divided by the square root of two. In this problem, the hypotenuse is equal to (1), and the leg is equal to (x). Therefore, one can say,

[tex]x = \frac{1}{\sqrt{2}}[/tex]

Rationalize the denominator,

[tex]\frac{1}{\sqrt{2}}*\frac{\sqrt{2}}{\sqrt{2}}\\\\\frac{\sqrt{2}}{2}[/tex]

Answer:

Step-by-step explanation:

a² + b²  = c²     look familiar?  it is the Pythagorean theorem

both side are the same length since both angles are the same some sort of Isosceles triangle rule I think    so side 1 = x   side 2 = x and  hypotenuse = 1

x² + x²  = 1²

   2x²   = 1

     x²   = 1/2

     x     =     √(1/2)      the denominator is  NOT rational in this FORM

     x    =    √1 / √2       multiple the numerator and the denominator by √2

     x    =    1 (√2) / (√2)(√2)

     x    =   √2 / √2²

     x    =   √2 / 2        finding a rational denominators means nothing

                                  just do more work and more typing for me,

                                  a silly MATH rule

  x = √2/2   =  0.7071        x = √(1/2)  = √(0.5)   =  0.7071   the SAME Number

 sorry, my rant of the day

Step-by-step explanation:

You know because:

The common factor between 3 and 6 is 3.

You can factor 2 x's from both parts and 2 y's.

Therefore, it would be

3x^2y^2.

Answer:

1). No, symbol won't be reversed

2.) No, symbol won't be reversed

3.) yes, symbol will be reversed

4.) No, symbol won't be reversed

Step-by-step explanation:

1.)

-10.5 < 3a

-10.5 /3 < 3a /3

-3.5 < 3 (No)

2.)

b/6 ≤ 7

Multiply both sides by 6

b/6 * 6 ≤ 7 * 6

b ≤ 42 (No)

3.)

-4.5c > 9

Dibide both sides by - 4.5

-4.5c / - 4.5 > 9/-4.5

c < 2 (yes)

4.)

–21/5 ≤ –5/2d

Multiply both sides by 2/5

-21/5 * 2/5 ≤ - 5/2d * 2/5

-21/2 ≤ - d

21/2 ≤ d (No)

Answer:

8cm

Step-by-step explanation:

Using the properties of a square, we know that a square has 4 sides, which are all of the same lengths.

Perimeter simply means the sum of all the outer lengths, so all we need to do is 32 ÷ 4, which = 8.
