Answer:

x = 15°

Step-by-step explanation:

Complementary angles are two angles whose sum = 90°

∠A + ∠B = 90°

3x + 45 = 90

3x = 45

x = 45/3

x = 15°

Answer:

#13. line QR is 26.

#14. a) x = 2 b) m = 6

Step-by-step explanation:

13. We can use the Pythagorean therom: a^2 + b^2 = c^2

We will substitue PQ for a and PR for b

10^2 + 24^2  = c^2

100 + 576 = c^2

100 + 576 = 676

Then, we find the square root of 676, which is 26.

14. a) 3(2x -1) = 9

we first use distributive property:

6x - 3 = 9

then we add 3 to both sides to counteract the -3:

6x = 12

we divide both sides by 6 to get x alone:

x = 2

b) 3m - 12 = 6

we add 12 to both sides to counteract the -12:

3m = 18

we divide both sides by 3:

m = 6

Answer:

Carros = 20

Motos = 30

Step-by-step explanation:

Carros = x

Motos = y

x + y = 50

4x + 2y = 140

x = 50 - y

4 (50-y) + 2y = 140 (substitución)

200 - 4y + 2y = 140

- 2y = 140 - 200

y = -60/-2

y = 30

x + 30 = 50

x = 50-30

x = 20

The two corresponding angles of the Triangles are equal and the the side between them is common between them (so equal).

So, the stated triangles are congruent by :

Answer:

y = 4x

Step-by-step explanation:

Since there are going to be four quizzes a month (x), we know that we will multiply the number of months (x) by the number of quizzes (4). However, because we don't know how many months there are, we can define the months as (x), and instead put the total (y) is equal to the number of quizzes per month (4), multiplied by the number of months (x). Out final result is

(y = 4x)

Answer:

y = 13 × [tex]4^{x}[/tex]

Step-by-step explanation:

Substitute the given values into the exponential

Using (0, 13 ) , then

13 = a[tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ) , so

a = 13

y = 13 [tex]b^{x}[/tex]

Using (3, 832 )

832 = 13 b³ ( divide both sides by 13 )

64 = b³ ( take cube root of both sides )

b = [tex]\sqrt[3]{64}[/tex] = 4

The exponential function is

y = 13 [tex](4)^{x}[/tex]

The surface area of the ship is 1500000 cm²

Scaling is used to either increase or decrease the size of a figure so as to create an image.

Given a scale of 1:200, this means that it is a scaling down (decrease in size) of the ship to create a model.

The surface area of the model is 7500 cm², hence that of the ship is:

Surface area of ship * (1 : 200) = surface area of model

Surface area of ship = surface area of model * 200 = 7500 * 200 = 1500000 cm²

The surface area of the ship is 1500000 cm²

Answer:19

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

The whole angle is 180 degrees.

90 degrees is already taken by the angle dividing the two vertical angles.

So you have 90 degrees left. then you have to subtract 49 from 90 to get the angle of '5t+6'.

So 5t+6 = 41, 41-6 is 35. 35/5 is 5, so t is 5.

I didn't go too far into explaining since you asked to not explain it.

The total price of the racket is $192.60 (first option).

A tax is a compulsory amount of money that is levied by the government or an agency of the government on goods and services. A sales tax is levied on the sales of goods and services.

The total price of the racket would include the amount of tax that would be paid.

Total price = (1 + tax/100) x initial price

Total price = (1 + 7%/100) x $180

Total price = (1 + 0.07) x $180

Total price = (1,07 x $180)  

Total price = $192.60
