What is the product of 6 1/2 and
9 1/4​

Answer:  tan(14x)

Step-by-step explanation:

Consider the Sum Formula for tan:

[tex]tan(A + B)=\dfrac{tan(A)+tan(B)}{1-tan(A)(tan(B)}\\\\\\tan(9x+5x)=\dfrac{tan(9x)+tan(5x)}{1-tan(9x)(tan(5x)}\\\\\\\large\boxed{tan(14x)}=\dfrac{tan(9x)+tan(5x)}{1-tan(9x)(tan(5x)}[/tex]

Answer:

[tex]\tan(4x)[/tex]

Step-by-Step Explanation:

Notice that this resembles the difference identity for tangent. Specifically:

[tex]\displaystyle \tan(\alpha-\beta)=\frac{\tan(\alpha)-\tan(\beta)}{1+\tan(\alpha)\tan(\beta)}[/tex]

So, given our equation, we can pretend that α=9x and β=5x. Therefore:

[tex]\displaystyle \frac{\tan(9x)-\tan(5x)}{1+\tan(9x)\tan(5x)}=\tan(9x-5x)=\tan(4x)[/tex]

Step-by-step explanation:

(a)

Since there are 360° in the complete pie chart the 40° represents

360° ÷ 40° = 9 parts of the chart

Since 40° represents 7 cars then there are a total of

9 × 7 = 63 cars in the car park

(b)

The circumference (C) of a circle is calculated as

C = πd ( d is the diameter )

Given C = 28 , then

Question:

Davis wants to pour 5 gallons of punch into ½ gallon jugs How many jugs will he need?

A. 2½

B. 5½

C. 10

D. 15

Answer:

Number of jugs = 10

Davis will need 10 jugs to pour 5 gallons of punch into ½ gallon jugs.

Step-by-step explanation:

David has 5 gallons of punch that he wants to pour into jugs.

The capacity of 1 jug is ½ gallon.

The required number of jugs may be found as

Number of jugs = gallons of punch/capacity of jug

For the given case, we have

Gallons of punch = 5

capacity of jug (in gallons) = ½ = 0.5

So, the required number of jugs is,

Number of jugs = 5/½

Number of jugs = 5/0.5

Number of jugs = 10

Therefore, Davis will need 10 jugs to pour 5 gallons of punch into ½ gallon jugs.

Answer:

y = - 4x + 17

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (4, 1) and (x₂, y₂ ) = (2, 9)

m = [tex]\frac{9-1}{2-4}[/tex] = [tex]\frac{8}{-2}[/tex] = - 4, thus

y = - 4x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (4, 1) , then

1 = - 16 + c ⇒ c = 1 + 16 = 17

y = - 4x + 17 ← equation of line

The reference angle of [tex]\frac{2\pi}{3}[/tex] is [tex]\frac{\pi}{3}[/tex]

Step-by-step explanation:

Given

[tex]\frac{2\pi}{3}[/tex]

Required

Which represent its reference angle

The very first step is to determine the quadrant of the given angle

For better understanding;

Convert [tex]\frac{2\pi}{3}[/tex] to degrees

[tex]\frac{2\pi}{3}[/tex] = [tex]\frac{2}{3} * 180[/tex]

[tex]\frac{2\pi}{3}[/tex] = [tex]\frac{2 * 180}{3}[/tex]

[tex]\frac{2\pi}{3}[/tex] = [tex]\frac{360}{3}[/tex]

[tex]\frac{2\pi}{3}[/tex] = [tex]120[/tex]

120 degrees in in the second quadrant; Hence, [tex]\frac{2\pi}{3}[/tex] is in the second quadrant

The reference angle of [tex]\frac{2\pi}{3}[/tex] is calculated using the following formula;

[tex]\pi - \frac{2\pi}{3}[/tex]

Rewrite [tex]\pi[/tex]

[tex]\pi - \frac{2\pi}{3} = \frac{3\pi}{3} - \frac{2\pi}{3}[/tex]

Take LCM

[tex]\pi - \frac{2\pi}{3} = \frac{3\pi - 2\pi}{3}[/tex]

[tex]\pi - \frac{2\pi}{3} = \frac{\pi}{3}[/tex]

Hence, the reference angle of [tex]\frac{2\pi}{3}[/tex] is [tex]\frac{\pi}{3}[/tex]

The reference angle for the angle 2π/3 is, π/3

Given that,

An angle is,

⇒ 2π/3

To determine the reference angle we need to find the quadrant of the given angle.

For this, we can convert angle into degree,

2π / 3 = 2 × 180 / 3

          = 120°

Since, 120 degrees is lies in the second quadrant.

Hence, 2π/3 is in the second quadrant.

So, The reference angle is,

⇒ π - 2π/3

⇒ π/3

Therefore, The reference angle for the angle 2π/3 is, π/3

Answer:

The cost of 12 gallons of gas and a quart of oil is 14·x - 30

Step-by-step explanation:

When adding variables, the coefficient of the variables are added followed by multiplication of the sum of the coefficients with variable as follows;

The cost of 12 gallons of gas = 12·x

The cost of a quart of oil is represented by 2·x - 30

Therefore, the cost of 12 gallons of gas and a quart of oil can be represented as follows;

12 gallons of gas and a quart of oil = 12·x + 2·x - 30

Which gives;

The cost of 12 gallons of gas and a quart of oil = 14·x - 30.

Answer:

The total time taken to reach C = 10 s

The total distance traveled by the body = 29 m

Step-by-step explanation:

Whereby the points are vertically oriented, we have;

v = u + at

Where;

a = Acceleration of the body = -1 m/s²

u = Initial velocity = 3 m/s

v = Final velocity, = 0 m/s at maximum height

t = Time taken

0 = 3 + (-1)× t

t = 3 s

The maximum height S is given as follows;

S = u·t  + 1/2·a·t² = 3×3 + 1/2×(-1)×3² = 4.5 m

Therefore, the total distance, [tex]S_t[/tex], from maximum height to C = 45 + 20 = 24.5 m

The total time is given from the total distance as follows;

[tex]S_t[/tex]  = u[tex]_m[/tex]·t[tex]_t[/tex]  + 1/2·a[tex]_d[/tex]·t[tex]_t[/tex]²

Where;

u[tex]_m[/tex] = Initial velocity from the maximum height = 0 m/s

a[tex]_d[/tex] = Downward acceleration = Opposite sign to upward acceleration = 1 m/s²

24.5  = 0·t[tex]_t[/tex]  + 1/2·(1)·t[tex]_t[/tex]²

49 = t[tex]_t[/tex]²

t[tex]_t[/tex] = √ 49 = 7 s

The total time taken to reach C = Initial time to reach maximum height + Time from maximum height = 3 s + 7 s = 10 s

The total time taken to reach C = 10 s

The total distance traveled by the body = Distance from B to maximum height + Distance from maximum height to C

The total distance traveled by the body = 4.5 m + 24.5 = 29 m.

The total distance traveled by the body = 29 m.

Answer:

166cm^2

Step-by-step explanation:

To calculate the area of the composite shape, find the area of rectangle and subtract the area of the triangle from it:

Area of rectangle =  16 x 11 = 176cm^2

Area of triangle = 1/2 x 4 x 5 = 10cm^2.

Since the shape is a rectangle, which the supposed shape of a triangle removed, subtract the area of triangle from that of rectangle:

176-10 = 166cm^2

Answer:

los pala de depotistas ingrese banca para tomar la decision

Step-by-step explanation:

Answer:

25 quarters, 5 half dollars

Step-by-step explanation:

let a = the number of half dollars in the jar

and b = the number of quarters

a + b = 30

0.5a + 0.25b = 8.75

multiply the second equation by -2 to get

-a - 0.5b = -17.5

Now add the new equation and the first to eliminate h

a + b = 30

-a - 0.5b = -17.5

----------------------------

0.5b = 12.5

b = 25

There are 25 quarters, so there must be 5 half dollars

Answer:

Step-by-step explanation:

Let half dollars be d and quarters be q

d + q = 30 thus, q = 30 - d

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

0.5d + 0.25q = 8.75 substitute for q:

0.5d + 0.25(30 - d) = 8.75

0.5d + 7.5 - 0.25d = 8.75

0.25d = 1.25

d = 5 so there are 5 half dollars in the jar

Therefore, there are 30 - 5 = 25 quarters in the jar

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Check:

25 x 0.25 = 6.25

5 x 0.5 = 2.5
