Answer:

x = 11

Step-by-step explanation:

35 + 5x = 90    {Complementary angles}

Subtract 35 from both sides

   5x = 90 - 35

  5x = 55            {Divide both sides by 5}

    x = 55/5

    x = 11

Answer:

n-4(32.5) > 300;n > 430

Step-by-step explanation:

Simplify: 300 = 4n - 130

Add 130 to each side. 430 = 4n

Divide by 4 on each side: 107.50= n

300 = 4(107.50) - 130? True

This tells us he must be paid $107.50 to make $300 exactly. Anything larger than $107.51 and up will make more than $300.

Answer:

arcsin0= 0 degrees

arccos0= 90degrees

arctan1= 45 degrees

Step-by-step explanation:

To get arcsin0, let the unknown value be x

sin x = 0

Take arcsin of both sides

arcsin(sinx) = arcsin 0

x = arcsin0

x = 0 degrees

Hence arcsin0 = 0degrees

For cos x = 0

Take arccos of both sides

arccos(cosx) = arccos 0

x = arcscos0

x = 90 degrees

Hence arccos0 = 90degrees

For tan x = 1

Take arctan of both sides

arctan(tanx) = arctan 1

x = arctan1

x = 45 degrees

Hence arctan1 = 45degrees

Answer:

B

Step-by-step explanation:

Combine like term.

Hers 7x and (-5x) are like terms

7x + 4x² - 5x = 7x - 5x + 4x²

                    = 2x + 4x²

Answer:24

Step-by-step explanation:Let the number we seek be X.

We are Given:

1). (5X+3 ) x (2) = 30

Expand and Rearrange.

(10X +6 ) = 30.

10X = 24.

2). X equals 2.4 . This is the answer for the number we seek.

Always check the answer.

This is Good Working Practice ALWAYS.

For Exams or similar remember:

Presentation (Neat & Tidy), Method & Layout (Show you understand), Accuracy.

All these count in most exams.

The first two points help greatly if your Answer is in error, but your METHOD Is CLEAR & CORECT.

Similarly, if the Check is wrong, mention this, but also, if the case, mention e.g. time ran out .. You may be credited as AWARE if your presentation and Method show you understood what to do and why.

CHECK: Substitute the answer for X into the original equation 1).

Equn. 1). (5X +3)*2 = 30.

Put in the value for X. Expand & Re-arrange.

(( 5 ).( 2.4 ) + ( 3 ).( 2 ) = 30.

( 12 + 6 ) = 30.

24 = 24. Checked & Agreed.

That’s about it.

Answer:

The ninth term? That would be 98.

Step-by-step explanation:

Notice how the numbers add 10 every time. If we keep doing that pattern until we get the ninth number, then we get this:

8, 18, 28, 38, 48, 58, 68, 78, 88, 98

Therefore, the answer is 98.

Step-by-step explanation:

Given the equation

[tex]12\left(x\:+\:8\right)\:=\:11x\:-\:5[/tex]

Expand 12(x + 8):  12x + 96

[tex]12x+96=11x-5[/tex]

Subtract 96 from both sides

[tex]12x+96-96=11x-5-96[/tex]

Simplify

[tex]12x=11x-101[/tex]

Subtract 11x from both sides

[tex]12x-11x=11x-101-11x[/tex]

Simplify

[tex]x=-101[/tex]

Therefore, we conclude that the solution is:

Remark

The diameter is 28 cm

Formula

Area = pi * r^2

Givens

pi = 22/7

r = d/2

r = 28/2

r = 14

Area = 22/7 * 14 * 14

Area = 22 * 2 * 14

Area = 44 * 14

Area = 616

Answer: 15

Step-by-step explanation:

For this question you have to use pythagoras' theorem.

Pythagoras' theorem is c²=a²+b²

So c is the hypotenuse and the hypotenuse is always opposite the right angle.

So the equation would be c²=9²+12²

Then 9²=81 and 12²=144

So the equation would then be c²=81+144

So c²=225

Then you just want to find c on it's own so you have to square root it which is 15.

Answer:

-6y+27

Step-by-step explanation:

-3*2y=-6y

-3*-9=27

because multiplying 2 negatives make a positive.

so,

-3(2y-9) = -6y+27

Answer:

m∠1 = 94°

m∠2 = 43°

m∠3 = 50°

m∠4 = 50°

m∠5 = 130°

m∠6 = 130°

Step-by-step explanation:

Answer:

m<1 = 80 degrees

m<2 = 57 degrees

m<3 = 57 degrees

m<4 = 43 degrees

m<5 = 137 degrees

m<5 = 123 degrees

Step-by-step explanation:

Angle 1: Vertical angles

Angle 2:

43+80 = 123, 180-123 = 57

Angle 3: Corresponding to m<2

Angle 4: Corresponding to the 43 degree angle

Angle 5: m<1 + m<2 = 137 degrees (Corresponding)

Angle 6: m<3+m<6 = 180 degrees. 180-57=123

Answer:

x = 135

Step-by-step explanation:

Cross multiply (Multiplicacao cruzada)

[tex]\frac{30}{x}=\frac{2}{9}[/tex]

2x = 270

(Now just divide both sides by X) So dividir os 2 lados por 2x

x = 135
