Work Out The Value Of XThe Diagram Is Not Drawn To Scale.

Answers

Answer 1

The shape is a pentagon.

The interior angles of a pentagon always add up to 540°.

When you add up all the labeled angles in the picture, you get (16x + 12).

16x + 12 = 540

16x = 528

X = 33

Answer 2

Step-by-step explanation:

4x-25+3x+25+3x+15+4×+2x-3=360

4x+3x+3x+4x+2x-25+25+15-2=360

16x +12=360

16x=360-12

16×÷16=348÷16

×=21.75

Answers

Answer:

x + 2y = -2

Step-by-step explanation:

Well let's examine the relation between x and y in a perpendicular line.

We can use the fact that for a line Ax + By = C, any line with equation Bx + (-A)y = D is perpendicular (swapping A and B gives a mirror image with respect to the line x=y and changing one of the signs gives a mirror image with respect to axis x or y. Those two together give a perpendicular line).

So we're looking for a line with equation x + 2y = D

We know what it passes through the point (6, -4), so let's input it into the equation x + 2y = D

6 + 2*(-4) = D

6 - 8 = D

D = -2

So the equation is x + 2y = -2

note that 2x + 4y = -4

or any other multiple also works.

The price of a visit to the dentist is $50. If the dentist fills any cavities, an additional charge of $100 per cavity
gets added to the bill.
If the dentist finds n cavities, what will the cost of the visit be?

Answers

Answer:

I believe the answer will be 50+100n dollars

Step-by-step explanation:

n is the number of cavities so however many cavities there is, it gets multiplied by 100, in this case, it is 100*n which is 100n. So your final cost would be 50+100n dollars.

Step-by-step explanation:

the equation is 6a² where a is the length of the edge

Answer:

150cm²

The difference between two numbers is 10 and their sum is 20. Find the biggest number.

Answers

Answer:

15

Step-by-step explanation:

x - y = 10, then x = 10 + y

x + y = 20

substitute for x:

10 + y + y = 20

2y = 10

y = 5

x = 10 + 5 = 15

300$ at 6% for 2 yrs what is the simple interest​

Answers

Answer:

Simple interest after 2 year = $36

Step-by-step explanation:

Given:

Amount invested = $300

Number of year amount invested = 2 year

Rate of interest per year = 6% = 6/100 = 0.06

Find:

Simple interest after 2 year

Computation:

Simple interest formula;

Simple interest = [Amount invested][Rate of interest][Number of year]

Simple interest after 2 year = [300][0.06][2]

Simple interest after 2 year = [18][2]

Simple interest after 2 year = $36

Given that sin θ= 1 / √2, we want to find the value of tan θ.
First, find the value of θ.

Answers

Answer:

value of tan θ = 1

Step-by-step explanation:

To find θ do the asin of 1/√2

θ = asin (1/√2)

θ = asin (0.707106781)

θ = 45

and then to find tan θ, do tan 45

tan 45 = 1

Step-by-step explanation:

you do 13x90 then divide by 5x

Answer: x=12

Step-by-step explanation:

We will use the Pythagorean Theorem since we know two sides and it is a right triangle

Pythagorean Theorem is a^2+b^2=c^2

a=5,b=x, c=13

(5)^2+(x)^2=(13)^2

25+(x)^2=169

Subtract 25 from both sides to start solving for x

(x)^2=144

Take the square root of both sides and get x=12

x=12
