Answer:

300 degrees

Step-by-step explanation:

After converting the given equation 5π/3 into degree, the value obtained will be equal to 300°.

If a mathematical operation includes at least two words that are connected by an operator and either comprise numbers, variables, or both, it is referred to as an expression.

The operations with reflection coefficients include adding, subtracting, multiplying, and dividing. In order to include terms into an expression, a mathematical operation like reduction, addition, multiplication, or division is used.

As per the given information in the question,

5π/3 radians to degree.

To convert radians to degree multiply it with 180/π

So,

5π/3 × 180/π

= 60 × 5

= 300°

Answer:

17.5m

Step-by-step explanation:

We solve using the formula

Height /Shadow

Height of flag staff = 7m

Shadow of flag staff = 8.2 m

Height of the building = x

Shadow of the building = 20.5

= 7/8.2 = x/20.5

Cross Multiply

8.2x = 7 × 20.5

x = 7 × 20.5/8.2

x = 143.5 / 8.2

x = 17.5m

The height of the building is 17.5 m

Answer:

Step-by-step explanation:

y=2x because

hello

so these angles you can apply the "vertically opposite angles are equal" rule

angle "A" is vertically opposite to 138º so therefore angle "A" is 138º

angle "B" is verticall opposite to 42º so therefore angle "B" is 42º

Answer:

5 miles

Step-by-step explanation:

2.3 miles south

then 4.5 miles east

a^2 + b^2 = c^2

a = 2.3 miles

b = 4.5 miles

(2.3)^2 + (4.5)^2 = c^2

c^2 = 25.54

[tex]\sqrt{c^2}[/tex] = [tex]\sqrt{25.54}[/tex]

c = 5.0

Answer:

138,000

Step-by-step explanation:

Add up expenses per SEMESTER

5650+3500+1250+1100=11,500

2 semesters in one year so double Semester amount

11,500x2=23,000

Multiply annual expense by 6 years

23,000x6=138,000

Answer: 37.5%

Step-by-step explanation:

Percentage = Given Quantity/Total Quantity*100

So here, it will be like: 45/120*100

                                    =0.375*100

                                    =37.5%

Answer:

A= -17

Step-by-step explanation:

A +-21 = -38

    +21     +21

-38+21= -17

A= -17

Answer:

a = -17

Step-by-step explanation:

To solve this, we need to get A alone:

A + -21 = -38

—- +21- +21

Remember, when you do something to one side, you need to do the same thing to the other side.

Now:

A = -17!

To check:

-17 + -21 = -38

Therefore, A = -17

Answer: 4

Step-by-step explanation:

We can expect that 4 of the next 20 pies sold will be blackberry pies, based on the proportion of blackberry pies in the recent sample of 15 pies.

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

If Tracy's Pie Shop recently sold 15 pies and 3 of them were blackberry pies.

Proportion of blackberry pies = 3/15

Proportion of blackberry pies = 0.2

So, in the recent sample of 15 pies, 20% were blackberry pies.

To estimate how many of the next 20 pies sold should be blackberry pies

Let us assume that the proportion of blackberry pies in the next sample of 20 pies will be similar to the proportion in the recent sample of 15 pies.

Therefore, we can use this proportion to estimate the number of blackberry pies in the next sample of 20 pies:

Number of blackberry pies = 0.2 x 20

Number of blackberry pies = 4

Therefore, we can expect that 4 of the next 20 pies sold will be blackberry pies, based on the proportion of blackberry pies in the recent sample of 15 pies.

Answer:

The statements that can be made about the parabola are;

The parabola opens towards the right

The equation of the parabola is (y - 1)² = 16 × (x + 1)

The parabola has a vertex at (-1, 1)

Step-by-step explanation:

The given focus of the parabola is (3, 1)

The directrix of the parabola, x = -5

Therefore, from the location of the directrix (on the x-axis) and the location of the focus relative to the directrix towards the positive direction of the x-axis relative to the directrix, the parabola opens towards the left of the coordinate chart

The general equation of the focus = (h + p, k)

The general equation of the directrix, x = h - p

Comparing with the values of the focus and the directrix of the given parabola, we have;

(3, 1) = (h + p, k)

-5 = h - p

Therefore, we get;

k = 1

h + p = 3...(1)

h - p = -5...(2)

Adding equation (1) to equation (2) gives;

h + h + p - p = 3 + (-5)

2·h = -2

h = -2/2 = -1

h = -1

From equation (1), we get;

h + p = -1 + p = 3

∴ p = 3 + 1 = 4

p = 4

The vertex of the parabola, (h, k) = (-1, 1)

The equation of the parabola in the form (y - k)² = 4·p·(x - h) is therefore, presented as follows;

The equation of the parabola = (y - 1)² = 4 × 4 × (x - (-1))

(y - 1)² = 16 × (x - (-1))

The equation of the parabola is (y - 1)² = 16 × (x + 1).
