Answer:

30%. Based on the given conditions, formulate: 12/40 Cross out the common factor: 3/10 Multiply a number.

Step-by-step explanation:

Answer:

a) m∠6 = 55 and m∠8= 55 - 20 --> m∠8= 35     x = 55

b) m∠7 = 40 and m∠9 = 140                                x = 40

c) m∠8 = 46 and m∠7 = 46                                  x = 18

d) m∠6 = 63 and m∠7 = 27                                  x = 9

Answer:

9:41

Step-by-step explanation:

Let's solve this in the most simplified version.

⇒ 4: 54

⇒ 13 Minutes Before

( 54 - 13)

= 4:41

Subtract 13 from 4

= -9

Eliminate the negative sign.

⇒ 9:00 .

Add the "41" to the time:

⇒ Final result: 9:41

To Find:

Area of the shaded region

Solution:

Area of shaded region:

[tex] \rm= Area \: of \: trapezium \: ABCD - Area \: of \: Trapezium \: EHGF[/tex]

We know that,

[tex] \rm \: Trapezium = 1/2 × (a+b)×h \: \: \: sq. units [/tex]

So,

[tex] \rm = 1/2 × (a+b)×h \: \: \: - 1/2 × (a+b)×h [/tex]

Trapezium ABCD:

According to the formula,

Trapezium EHGF:

Substitute:

[tex] \tt= \cfrac{1}{2} (40 + 24) \times 25 - \cfrac{1}{2} (30 + 16) \times \: 20[/tex]

[tex]\tt= \cfrac{1}{2} (64) \times 25 - \cfrac{1}{2} (46) \times \: 20[/tex]

[tex]\tt = \cfrac{1}{2} \times 1600 - \cfrac{1}{2} \times 920[/tex]

[tex] \tt \: = 800 - 460[/tex]

[tex] \rm = 340 \: cm {}^{2} \: or \: sq. \: cm[/tex]

Thus, the area of the shaded region will be 340 cm^2 .

$3062

Step by Step Explanation:

Arturo's rent can also be written as an expression

2t + 50

This is basically showing that two of Tom's rent plus $50 gives you his brother's rent.

So 2(1506) + 50

3012 + 50

Answer:

=0.291

Step-by-step explanation:

number of residents who have completed some college =5372

number of residents who has completed college and age group 20-29years=1563

1563/5372

=0.29095

Let's take this fun problem step-by-step:

Let's first analyze the triangle:  ΔBRE

  ∠B + ∠E + ∠R = 180

  45 + 35 + ∠R = 180

    ∠R = 100   ⇒ ∠BRE = 100 degrees

Now let's analyze ΔAQD

 ∠A + ∠Q + ∠D = 180

 30 + ∠Q + 50 = 180

    ∠Q = 100 degrees ⇒ ∠AQD = 180 degrees

Now let's consider another fact:

           ⇒ meaning that ∠AQD + ∠RQC = 180 degrees

              ⇒ ∠RQC = 180 degrees - ∠AQD = 180 - 100 = 80 degrees

            ⇒ meaning that ∠BRE + ∠BRC = 180 degrees

                ⇔ ∠BRC = 180 degrees - ∠BRE = 180 - 100 = 80 degrees

Now let's consider ΔQRC:

  ∠BRC + ∠RQC + ∠QCR = 180 degrees

   80 + 80 + x = 180

         x = 20 degrees

Answer: 20 degrees

Answer:

C = 8.45 m

Step-by-step explanation:

The equation to find the circumference of a circle is:

[tex]C=2\pi r[/tex]

r = radius

To find the radius, divide the diameter by 2:

r = 2.69 m/2 = 1.345 m

Now, plug the radius into the equation:

[tex]C = 2\pi (1.345)[/tex]

Use a calculator to get the final answer:

C = 8.45 m

a)The high and low tides occur at when the value of cos function is an odd and even multiple of the π respectively.

b)The respective depths of the ocean at high tides and low tides will be 8 ft and 2 ft.

A function is a statement, rule, or law that specifies the connection between two variables. Functions are common in mathematics and are required for the formulation of physical connections.

Modeling the depth of the Atlantic Ocean at a channel buoy off the coast of Maine is;

[tex]\rm y = 5-3 cos (\frac{\pi}{6} t)[/tex]

a) High tide's value of 'y' when the value of y is maximum. value of cosine is minimum.

The minimum value of cosθ  = 1.

The standard form to write the cos function is as;

θ=(2n+1)π

Whenever. high tides occur when it equals odd multiples of π. Similarly, at a Value of even multiples of even function, low tides are at their peak.

Hence,the high and low tides occur at when the value of cos function is an odd and even multiple of the π respectively.

At high tide;

соsӨ = - 1 (min value)

y= 5-3(-1)

y = 5+3

y=8 ft

At low tide,соsӨ = + 1 (max value)

y =5-3(1)

y= 5-3

y= 2

Hence,the respective depths of the ocean at high tides and low tides will be 8 ft and 2 ft.

Answer:

2 .3   and  5  

Step-by-step explanation:

Answer:

see below

Step-by-step explanation:

distance / rate = time

x = walking distance        20 -x = biking distance

x / 4 m/hr   +   (20-x) / 12 m/hr    =   3 hours

x/4   + ( 20-x) /12 = 3     multiply both sides of the equation by 12  

3x  + 20 -x  = 36

2x = 16

x = 8      8 miles walking    then   12 miles biking
