Help please:
Rewrite the problem in terms of some using the double-angle formula.

Answer:

x = 26

angle QOR = 31

angle ROS = 59

Step-by-step explanation:

[tex](x + 5) + (2x + 7) = 90\\ 2x + x + 5 + 7 = 90 \\ 3x + 12 = 90 \\ 3x = 90 - 12 \\ 3x = 78 \\ x = 78 \div 3 \\ x = 26[/tex]

Sub x in

[tex](x + 5) \\ 26 + 5 = 31[/tex]

and

[tex](2 \times 26 + 7) \\ = 52 + 7 \\ = 59[/tex]

Answer:

6n-3

Step-by-step explanation:

You can see the sequence is ascending by 6 each time so the nth term is 6n.

The 'zero term' would be -3 so the equation would be 6n-3.

Answer:

3. The amount of wallpaper for a wall in a bedroom

Step-by-step explanation:

1. The number of towels I can fit in a bathroom cabinet

No, sounds more like volume, since a cabinet has space inside.

2. The amount of ribbon used to decorate from one end of a room to the another

No, sounds like perimeter, since a ribbon would need to cover space in one direction.
3. The amount of wallpaper for a wall in a bedroom

Yes, wallpaper is applied in 2 directions and lays flat on a surface to cover a certain area.

Answer:y = 2/3x + 4

So

The equation becomes

Where m is miles driven

The no. of miles not including any tip the taxi traveled is 22 miles.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, The taxi company charged a pick-up fee of $3.20 plus $2 per mile.

Let, 'm' be the no. of miles and the total fare was $47.20.

Therefore, The numerical form of these statements is,

2m + 3.20 = 47.20.

2m = 47.20 - 3.20.

2m = 44.

m = 44/2.

m = 22.

So, The taxi traveled 22 miles.

Answer:

10 times

Step-by-step explanation:

We have two separate equations that represent this situation:

0.75x   ----> which represents recycling center #1

0.25x + 5.00   -----> which represents recycling center #2

To find the amount of times you would need to visit the recycling centers for the total cost to be the same, put both of these equations equal to each other:

0.75x = 0.25x + 5.00

Now, solve:

0.75x = 0.25x + 5.00                Subtract 0.25x from 0.75x

0.50x = 5.00                              Divide 5.00 by 0.50

x = 10

Thus, you would need to visit the recycling centers 10 times for the total cost to be the same.

Let's check this answer by plugging 10 into both equations:

0.75(10) = 7.5

0.25(10) + 5.00 = 7.5

Since both of the answers are the same, then 10 is the correct answer!

I hope this helps! Good luck!

Answer:  0.7

This is because the 7 is in the tenths place

0.7 = 7 tenths = 7/10

You could also use long division or a calculator to get this decimal value.

Answer:

0.7

Step-by-step explanation:

To convert a decimal to a fraction, didvide the numerator by the denominator.

7 ÷ 10 = 0.7

note: This fraction is over 10. Any fraction over 10 will have a decimal value in the tenths place.

Answer:

Atotal=60cm2

Step-by-step explanation:

A1=BH

=6cm*5cm

=30cm2

A2=1/2 BH

=1/2(12cm)(5cm)

=6cm*5cm

=30cm2

A1+A2=Atotal

30cm2+30cm2=Atotal

60cm2=Atotal

Step-by-step explanation:

the area of such a regular shape with n sides is the sum of n isoceles triangles (meaning each triangle has equally long legs) from the center to 2 neighboring corners.

the area of a triangle is

baseline × height / 2

so, for these triangles that means

shape side length × apothem / 2

in our case, n = 6, the side length = 5 cm, the apothem is 4.3 cm. and we get as total area

6 × 5×4.3 / 2 = 3 × 5 × 4.3 = 15 × 4.3 = 64.5 cm²

Answer:

y=30 and x =25.98

Step-by-step explanation:

Solving For Y value:

Sin30 = 15/y

0.5 = 15/y

y0.5 = 15

y = 15 / 0.5

y=30

Solving For X value:

Tan30 = 15 / x

0.58 = 15 / x

x0.58 = 15

x= 15/0.58

x =25.98

The probability that the next chew Liam removes from the bag will be a cherry chew is 0.03.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

We have:

Liam performs the experiment 62 times

Total number of outcomes = 62

A pineapple chew was selected 58 times.

A cherry chew was selected 2 times.

A lime chew was selected 2 times.

Now, the probability that the next chew Liam removes from the bag will be cherry chew:

P = 2/62

P = 1/31

P = 0.0322  or 0.03

Thus, the probability that the next chew Liam removes from the bag will be a cherry chew is 0.03.
