Answer:

39.99

.................

Answer:

39 99

Step-by-step explanation:

39 99/ 100 = (39 x 100 + 99) / 100

= 3999/100

= 39.99

Answer:

The first transit on one side of the trench is 18 ft higher than the other side of the trench. The transit is set at 4.5 above ground, therefore the transit lens is 18' + 4.5' = 22.5' above the location on the other side of the trench. The angle of depression is the angle formed by the horizontal and the line of sight to the other side and it is given as 31°. This forms a right angle triangle with height of 22.5' and an interior angle of 31°, Then

tan( 31°) = Height / base, with the base representing the width of the trench

base = Height / tan(31°) = 22.5' / tan(31°) = 37.45' is the width of the trench

Answer:

So the trench is 37.5 feet wide

Step-by-step explanation:

The trench with telescope is 18 feet higher than the other.

The height of telescope is 4.5 feet.

Total height = 18 + 4.5 = 22.5

Now, we can see in the figure that the distances between telescope and the opposite trench, the height and width makes a right angled triangle.

So, perpendicular = total height = 22.5

base = wideness of the trench

We know,

Tan 31 = p/b

tan 31 = 22.5/b

b = 22.5 / 0.6

b = 37.5

Answer:

Step-by-step explanation:

The foci are horizontally aligned.

horizontal ellipse:

(x-h)²/a² + (y-k)²/b² = 1

center (h,k)

vertices (h±a,k)

length of minor axis = 2b

foci (h±c,k), c² = a²-b²

Apply your data and solve for h, k, a, and b.

foci (±3√19, 6)

h = 0

k = 6

Length of minor axis = 2b = 10

b = 5

foci (h±3√19, 6)

c = 3√19

c³ = a² - b²

171 = a² - 25

a²  = 196

x²/196 + (y-6)²/25 = 1

The measure of angle A from the given right angle triangle ABC is 55.15°.

Heights and Distances is a study about the applications of Trigonometry. It has many real-life applications, such as measuring the object’s height, depth of the object, the distance between two celestial objects etc. The formulas and the ratios of trigonometry are helpful in the study of heights and distances.

From the given right angle triangle ABC, we have

AB=7 units and AC=4 units

Now, cosA=AC/AB

cosA=4/7

Solve the trigonometric equation by isolating the function and then taking the inverse. Use the period to find the full set of all solutions.

A= 55.15°

Therefore, the measure of angle A is 55.15°.

Answer:

Blue balloons : 63, 7, 14

Red balloons : 45, 5, 10

14 balloons in a group that has 10 red balloons

Step-by-step explanation:

First, 63/9 = 7, so 45/9 = 5.

Second,  5 x 2 = 10, so 7 x 2 = 14

Answer:

x=85

y=45

Step-by-step explanation:

using the sum of a straight angle:

x+95=180

x=85

then we can use the sum of the inner angles of a triangle:

50+85+y=180

y=45

Answer:

Speed = 1.0625 km / sec

Step-by-step explanation:

Distance = 34 kilometers

Time = 32 seconds

Speed = ?

The relationship between these quantities is given as;

Speed =  Distance / Time

Inserting the values;

Speed = 34 km / 32 sec

Speed = 1.0625 km / sec

Answer:

a squared + b squared = c squared

option 1 is the right answered. pythagoras theorum basically helps you find the third side/line of the triangle a^2 + b^2 = c^2.

Step-by-step explanation:

Answer:(c)

Step-by-step explanation:

Given

Inequality is [tex]10x+18\leq 238[/tex]

Subtract [tex]18[/tex] from both side of the inequality

[tex]\Rightarrow 10x+18-18\leq 238-18\\\Rightarrow 10x\leq 220[/tex]

divide both sides by 10

[tex]\Rightarrow \frac{10x}{10}\leq \frac{220}{10}\\\Rightarrow x\leq 22[/tex]

Therefore, maximum value of x can be 22 i.e. at most 22 days

The Answer is 1,000

Answer:

The point is not a solution of the two equations

Step-by-step explanation:

2x+y=4

y=-2x+4

Subsitute it into the other equation

2x+7(-2x+4)=14

2x-14x+28=14

-12x+28=14

-12x=-14

x= 7/6 or 1.17

Plug this back into the original equation

y=-2x+4

y=-2(1.17)+4

y=1.66

The solution of these two equations is (1.17, 1.66) which doesn't match the given point of (4,-4), so the point is not a solution of the two equations.

Step-by-step explanation:

The formula of probability is = no of possible cases upon number of total cases

Answer:

The perimeter of this figure can be found by counting the number of 0.5 lines it takes to go one full circle around the figure.

In this case, there are 42 of these 0.5 lines.

So, if there  are 42 of these 0.5 lines, the  perimeter of the  figure would just be: 42 times 0.5, which is equal to 21 cm.

Answer:

18 cm

Step-by-step explanation:

From the question above,

Area of a rhombus

A = d₁d₂/2.................. Equation 1

Where A = area of the rhombus, d₁ = length of one diagonal, d₂ = length of the other diagonal

make d₂ the subject of the equation

d₂ = 2A/d₁...............  equation 2

Given: A = 72 cm², d₁ = 8 cm

Substitute these values into equation 2

d₂ = (2×72)/8

d₂ = 144/8

d₂ = 18 cm.

Answer:

11[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using the rule of radicals

[tex]\sqrt{a}[/tex] × [tex]\sqrt{b}[/tex] ⇔ [tex]\sqrt{ab}[/tex]

Simplify [tex]\sqrt{27}[/tex]

[tex]\sqrt{27}[/tex]

= [tex]\sqrt{9(3)}[/tex]

= [tex]\sqrt{9}[/tex] × [tex]\sqrt{3}[/tex]

= 3[tex]\sqrt{3}[/tex]

Then

5[tex]\sqrt{3}[/tex] + 2(3[tex]\sqrt{3}[/tex] )

= 5[tex]\sqrt{3}[/tex] + 6[tex]\sqrt{3}[/tex]

= 11[tex]\sqrt{3}[/tex]
