Step-by-step explanation:

Answer:

The angle F = 47.25°

Step-by-step explanation:

Step(i):-

Given that f =42inches  and  e = 39 inches

Given that ∠E = 43°

By using sine rule

                 [tex]\frac{a}{sinA} = \frac{b}{sinB} = \frac{C}{sinC} = 2R[/tex]

                [tex]\frac{e}{sinE} = \frac{f}{sinF}[/tex]

 ⇒          [tex]\frac{39}{sin43} = \frac{42}{sinF}[/tex]

  Cross multiplication , we get

⇒       39 sin F = 42 × sin 43°

             [tex]sin F = \frac{42 X 0.68199}{39}[/tex]

⇒           sin F = 0.734459

Step(ii):-

⇒       sin⁻¹ (sin F)= sin ⁻¹ ( 0.734459)

⇒            F = 47.25

The angle F = 47.25°

Answer:

[tex]10\ \text{sq. units}[/tex]

Step-by-step explanation:

The parabola's are

[tex]y=-x^2+9[/tex]

[tex]y=2x^2-3[/tex]

So

[tex]-x^2+9=2x^2-3\\\Rightarrow 12=3x^2\\\Rightarrow \\\Rightarrow x=\sqrt{\dfrac{12}{3}}\\\Rightarrow x=\pm 2[/tex]

[tex]y=-x^2+9=-(2)^2+9\\\Rightarrow y=5[/tex]

[tex]y=-(-2)^2+9=5[/tex]

So, the points at which the parabola's intersect each other is [tex](2,5)[/tex] and [tex](-2,5)[/tex]

The three points of the triangle are [tex](2,5)[/tex], [tex](-2,5)[/tex] and [tex](0,0)[/tex]

Area of a triangle is given by

[tex]A=\dfrac{1}{2}[x_1(y_2-y_3) + x_2(y_3-y_1) + x_3(y_1-y_2)]\\\Rightarrow A=\dfrac{1}{2}[2(5-0)+(-2)(0-5)+0(5-5)]\\\Rightarrow A=10\ \text{sq. units}[/tex]

Area of the triangle formed is [tex]10\ \text{sq. units}[/tex].

Answer:

(1,1)

Step-by-step explanation:

With the midpoint formula, we're basically finding the average of the two variables, x and y.

Formula: [tex](\frac{x_{1} + {x_2} }{2}, \frac{_{1} + {y_2} }{2} )[/tex]

[tex](\frac{{-1} + {3}}{2} , \frac{{-2} + {4}}{2} )[/tex]

[tex](\frac{2}{2}, \frac{2}{2})[/tex]

(1,1)

Answer:

no

Step-by-step explanation:

the area of the whole box is 17,280 cubic units because 24x24x30=17,280. If each cubic unit is .004 lbs then multiply 17,280 by .004. And it equals 69.12 lbs. And 69 is bigger than 30, so no he cant lift it.

Answer:

since the rate is the same for both trains, and we know that the distance train A travels plus the distance train B travels equals 562.5 miles, we can use the D(istance) = R(ate) * T(ime) formula to solve this.

Train A:

da = R * 4

Train B:

db = R * 3.5 (using 3.5 instead of 3 and 1/2)

Solve for R:

R * 4 + R * 3.5 = 562.5

7.5 * R = 562.5

R = 75

The trains are traveling at 75 miles per hour.

Step-by-step explanation:

Answer:

speed = distance / time

since they are moving in opposite direction, the time is the sum of the two times = 2 1/2 + 4 = 6 1/2 = 13/2

speed = 585/(13/2) = 90 miles per hour.

Answer:

Not bad

Step-by-step explanation:

According to the internet, there are a number of factors to consider before estimating your waste percentage when buying carpets.

You may have to check the shape of your room, if it has multiple walls or if it is just complicated. For this kind you can estimate a 20% waste factor.

But for uncomplicated rooms having the same width as the carpet, the rule of thumb is to add a 10% waste factor to the square footage area.

Answer: B. 59°F

Step-by-step explanation:

Range = Maximum - MInimum.

From the given temperatures, Maximum temperature = 99 degrees Fahrenheit

Minimum temperature = 40 degrees Fahrenheit

Range = Maximum temperature  - Minimum temperature

i.e. Range =99-40 = 59 degrees Fahrenheit

Hence, the range of the temperatures = 59°F i.e. B is the correct option.
