solve 0.5 cos 30=3x​

Answer:

50

Step-by-step explanation:

The triangle is an isosceles triangle as shown with the lines on the sides of the triangles. That means the unknown angle is 35 degrees since angle Q cannot be 35 degrees. Solve the equation:

2x + 80 = 180

2x = 100

x = 50

Answer:

The cyclist can travel 0.9 miles in 2 minutes.

Step-by-step explanation:

1 hour = 60 minutes

Set up a conversion equation:

27 mi/1 hr × 1hr/60 mins

It is easier to see when writing it on paper, but the fractions are set up in a way to cancel the units out until the only units left are miles and minutes

After multiplying the numerators together and then multiplying the denominators together, you should reach the answer:

27 mi/60 mins

The cyclist can travel 27 miles in 60 minutes, but how many miles can he travel in 2 minutes?

Set up an equation:

Variable x = number of miles

27 mi/60 mins = x/2 mins

Cross multiply

27 × 2 = 60 × x

54 = 60x

Divide both sides by 60

0.9 = x

Answer:

3x²/(3x - 9y)

This should be the simplest form.

Step-by-step explanation:

Combine the fractions:

(5x² - 2x²)/((6x - 6y) - (3y - 3x))

Combine like terms:

3x²/(6x - 3x - 6y - 3y)

Solve.

3x²/(3x - 9y)

Answer:

9x^2      

======

6(x - y)

Step-by-step explanation:

Begin by switching the - to a plus. Switch the x and y in the second denominator.

5x^2              2x^2

=====      +    ======

6x - 6y          3x - 3y

Pull out the common factors in both denominators. Use the distributive property.

5x^2              2x^2

=====      +    ======

6(x - y)          3(x - y)

Multiply both the numerator and denominator by 2 on the left had fraction.

5x^2              2*2x^2

=====      +    ======

6(x - y)          2*3(x - y)

5x^2                4x^2

=====      +    ======

6(x - y)          6(x - y)

Put both numerators over a common denominator. Notice that the + sign shifts up.  It shifts up because both fractions have been changed to a common denominator.

5x^2        +        4x^2

===================

          6(x - y)

Combine the two numerators since they are of the same power.

9x^2

6(x - y)

Answer: 0.70h

Step-by-step explanation:

The hat is being sold at a 30% discount. The expression that shows this will be:

Price = h - 0.3h

When the 0.3h is subtracted from h, we have:

= 0.7h

Another way to get to that expression:

Hat is being sold at 30% discount which means that 30% has been removed from the value leaving:

= 100% - 30%

= 70%

Price is now 70% * Normal price which is denoted as h.

= 70% * h = 0.7h

Answer:

[tex]3174cm^{2}[/tex]

Step-by-step explanation:

Each square has an area of [tex]529cm^{2}[/tex]

So we multiply that by the number of squares which is 6.

Answer:

87

Step-by-step explanation:

first find x

all triangles = 180°

180=32+2x+x+15

combine like terms

180=47+3x

180-47=133

133=3x

133/3=44.334 or 44 1/3

2(44.334)= 88.66 ooor 87 if you round it

Answer:

The markup was 143.75%.

Step-by-step explanation:

In order to find the markup, you have to find the difference between the price the store paid for the pair of shoes and the price they sold them for, then divide that by the price they paid for the shoes and the result has to be multiplied for 100:

((78-32)/32)*100=(46/32)*100=1.4375*100=143.75%

According to this, the answer is that the markup was 143.75%.

Answer:

c = 0.15m + 45

Step-by-step explanation:

Generally, we have the equation of a straight line as;

y = mx + b

where m is the slope and b is the y-intercept

To get the value of m, we can use the slope equation

m = (y2-y1)/(x2-x1)

Let us select two points to use from the table

we have;

(40,51) and (20,48)

So substituting these values;

m = (48-51)/(20-40) = 0.15

So we have the partially completed equation as;

y = 0.15x + b

To get the value of b, we use any of the points

Using the last, we have

51 = 0.15(40) + b

b = 45

So we have the complete equation as;

y = 0.15x + 45

using the terms in the question, we have;

c = 0.15m + 45

Answer:

56

Step-by-step explanation:

If there are 70 total magazines, and 80% are womens, then you just multiply 70 * .80 = .56

Answer:

a)

Tom

Tax = (11/100) × 13

Tax = $1.43

Tom paid 13 +1.43 = $14.43

Lyn

Tax = (9/100)× 21

Tax = $1.89

Lyn paid 21 + 1.89 = $22.89

b) Lyn paid more for taxes.

Answer:

Each customer bought 45 boxes which is equivalent to mangoes 3240 in total.

Step-by-step explanation:

1. Subtract 3 boxes from the total of 138 imported boxes. ( 3 boxes are the 72 mangoes for his friends )

2. Divide 135 by 3 ( The amount of customers ) = 45 boxes per customer.

3. 45 x 24 ( The amount of mangoes in each box ) = 1080

4. 45 boxes/1080 mangoes per customer.

To recheck:

1080 x 3 ( The amount of customers again ) = 3240.

135 x 24 ( The amount of mangoes per box ) = 3240.

I Hope this helped! :)

Answer:

4 (2a+3b)^2

Step-by-step explanation:

take 4 common factor

4 (4a^2 + 12ab + 9b^2) =  4 (2a+3b)^2

Answer:

r = 2.7%

Step-by-step explanation:

Interest rate compounded continuously

r = ln(A/P) / t

Where,

r = interest rate

A = future value

P = principal

t = time

r = ln(A/P) / t

r = ln(13,006.40/8,000) / 18

= ln(1.6258) / 18

= 0.4860000023303 / 18

= 0.0270000001294

Approximately

r = 0.027

Convert value of r to percentage

r = 0.27 × 100

r = 2.7%
