Answer:

7.8

Step-by-step explanation:

Sine 50=6/x

x= 6/Sine 50

x=7.8

Answer:

h ≈ 7.8 cm

Step-by-step explanation:

Use sines to determine the length of the hypotenuse. You know that there is a 50 degree angle, and that the ratio for sine is opposite/hypotenuse. You know that the opposite side from that angle is 6 cm, so you can set up the following equation:

sin50 = 6/h

sin50h = 6

h ≈ 7.8 cm

Answer: Angle B

Step-by-step explanation:

Since the two shapes are similar. The angles stay with the shape. This means that angle M should correspond to angle B.

Answer: angle b .

Answer:

92 ft  

Step-by-step explanation:

Assume the garden has the shape shown below.

The length of fencing equals the distance around three sides of the rectangle plus that around the semicircle.

1. Around the rectangle

Distance = 28 ft + 14 ft + 28 ft = 70 ft

2. Around the semicircle

For a circle.

C = 2πr

For the semicircle,

½C =½(2πr) = πr  

D = 14 ft, so

r =    7 ft

[tex]\text{Distance} = \dfrac{22}{7} \times \text{7 ft} = \text{22 ft}[/tex]

3. Total distance

Distance = 70 ft + 22 ft = 92 ft

Jordan will need 92 ft of fencing.

Answer:

y = 4/3 x - 3.

Step-by-step explanation:

III

y - 5 = 4/3(x - 6)

y = 4/3(x - 6) + 5

y = 4/3 x - 8 + 5

y = 4/3 x - 3.

Answer:

3.5°/hour

Step-by-step explanation:

Rate of change of temperature=change in temperature/Change in time

Change in temperature

=82° - 54°

=28°

Change in time=3:00pm - 7:00am

=8:00 hours

Rate of change of temperature=28°/8 hours

=3.5°/hour

Answer:

The rate of temperature change is 3.5 degree celcius per hour

Step-by-step explanation:

Here, we want to calculate the rate of change of temperature

Firstly, we calculate the number of hours it took the temperature to change

that mathematically = 15:00(3pm) - 7:00(7 am) = 8 hours

now let’s calculate the temperature rise = 82-54 = 28

The rate of temperature change is thus = change in temperature/ number of hours taken

= 28/8 = 3.5 degree celcius per hour

Answer:

She should choose the Simply Savings Bank, since she'll earn around 2 dollars more in comparison to the other bank.

Step-by-step explanation:

A simple interest rate account yields a return that follows the formula below:

[tex]return = C + C*r*t[/tex]

Where C is the invested money, r is the interest rate and t is the elapsed time in years.

While a compound interest rate account yields a return that follows the formula below:

[tex]return = C*e^{r*t}[/tex]

Therefore for the Simply Saving Bank she'll earn:

[tex]return_{1} = 200 + 200*0.1*5\\return_{1} = 200 + 100\\retrun_{1} = 300[/tex]

While the Capital Bank she'll earn:

[tex]return_2 = 200*e^{0.08*5}\\return_2 = 200*e^{0.4}\\return_2 = 200*1.49182\\return_2 = 298.364[/tex]

She should choose the Simply Savings Bank, since she'll earn around 2 dollars more in comparison to the other bank.

Answer:

AE = 43.2 units

Step-by-step explanation:

As per the given question image, it can be seen that in the [tex]\triangle ADC \text { and }\triangle AEB :[/tex]

1. [tex]\angle B = \angle C = 90^\circ[/tex]

2. [tex]\angle A[/tex] is common to both the triangles.

3. Two angles are common, so the third angle [tex]\angle E[/tex] is also equal to [tex]\angle D[/tex].

All the three angles in the [tex]\triangle ADC \text { and }\triangle AEB[/tex] are equal to each other, hence the triangles are similar.

As per the property of similar triangles, the ratio of their sides will be equal.

AB : AC = AE : AD

AC = 88 units

BC = 55 units

AB = AC - AB = 33 units

Let side AE = [tex]x[/tex] units

Side AD = AE + ED

So, AD = [tex]x + 72[/tex]

Using the ratio:

[tex]\dfrac{AB}{AC} = \dfrac{AE}{AD}\\\Rightarrow \dfrac{33}{55} = \dfrac{x}{x+72}\\\Rightarrow 55x = 33 \times 72\\\Rightarrow x = \dfrac{3\times 72}{5}\\\Rightarrow x = 43.2\ units[/tex]

So, AE = 43.2 units

Answer: 9

Step-by-step explanation:

The reason for this answer, is because when you decide 18 by 6 it gives you 3. Which means that when you devide 27 by 3 it will give you your answer. 9. You can make sure it’s correct when you do the math. 27/9=3. 18/6=3.

This way, your answers are equivalent to each other.

If you found this answer helpful, give it a five-star rating and a thanks! It would really mean a lot!

Answer:

a=9

Step-by-step explanation:cross multiply

Answer:

(16)^3 = (7 + 9)^3 = 7^3 + 9^3 + 3 x 7^2 x 9 + 3 x 9^2 x 7

=>(16)^3 + (-7)^3 + (-9)^3 = (-7)^3 + (-9)^3 + 7^3 + 9^3 + 3 x 7^2 x 9 + 3 x 9^2 x 7

                                    =  [(-7)^3 + 7^3] + [9^3 + (-9)^3] + 3 x 7^2 x 9 + 3x9^2x7

                                    =  0 + 0 + 3 x 7^2 x 9 + 3 x 9^2 x 7

                                    = 3 x 7^2 x 9 + 3 x 9^2 x 7

                                    = 3 x 9 x 7 x (7 + 9)

                                    = 3 x 7 x 9 x 16

                                    = 3 x 7 x 9 x 8 x 2

                                    = 6 x 7 x 8 x 9

                                    = 3024

Hope this helps!

Answer:

We know by given that OC bisects the angle, which means it divides the angle AOB in two equal parts. So,

[tex]m \angle AOB = 3x +5 + 3x +5 =6x+10[/tex]

If [tex]x=9[/tex], then we use this value to find each angle.

[tex]m \angle BOC = 3x+5 =3(9)+5=27+5=32[/tex]

Therefore, angles BOC and AOC measure 32°.

You can compute the slope of a line by using the slope formula. This is given by:

slope,m=(change in y-axis)/(change in x-axis)

           =(Δ y-axis)/(Δ x-axis)

Given the points (x1,y1) and (x,y) from a linear graph, then:

slope m will be:

          m=(y-y1)/(x-x1)

You can compute the slope of a line by using the slope formula.

Answer:

not sure if that is the Answers

The equation of a line is y = mx where m is the slope. That line passes through the origin. If you want it to pass through some point (a, b) you subtract the coordinates like this: y - b = m (x - a). That is the point-slope form, and you can rewrite it in other forms if it is convenient. You may do this with any point on the line.

Answer:

0

Step-by-step explanation:

Given a polynomial p(x) divided by (x + h), then the remainder is

p(- h)

Here divisor is (x + 1), so evaluate p(- 1) for remainder

p(- 1) = [tex](-1)^{5}[/tex] + [tex](-1)^{4}[/tex] + (- 1)³ + (- 1)² + 2(- 1) + 2

        = - 1 + 1 - 1 + 1 - 2 + 2

        = 0

This means that (x + 1) is a factor of p(x)

[tex]2x - z - 5 + {2z}^{2} [/tex]

Step-by-step explanation:

The coefficient of x is 2= 2x

the coefficient of z is -1 which is = (-1)z= -z

the constant term is less than zero which means that the constant term is a negative number.

so the answer becomes

[tex]2x - z - 5 + {2} { (- 1)}^{2} [/tex]

which is =2x-z-3

Answer:

2 x minus z minus 5 + 2 z squared
