Answer 1

Answer:

? = 130°

Step-by-step explanation:

The sum of all angles inside a triangle is always 180°.

180 - 20 - 30 = 130°

130° is vertical to the ?, therefore, the ? = 130°

Jack bought a new boat for $36,000. The value of the boat continuously

depreciates at a rate of 15%. Find the value of the boat after 5 years.

a. $17,005

b. $7,621

c. $7,240

d. $4,140

Answers

Answer:

$15973.4

Step-by-step explanation:

The formula for depreciation is:

a(1 - r)^t

a = Initial value =$36,000

r = depreciation rate = 15% = 0.15

t = time in years = 5 years

The depreciation value = $36000 × (1 - 0.15)⁵

= 36000(0.85)⁵

= $15973.39125

Approximately = $15973.4

The value of the boat is $15,973 after 5 years.

Given that,

New boat cost is (A)  $36,000.Depreciation rate is (r) 15%.We need to find the value of boat after (t) 5 years.

According to the scenario, computation of the given data are as follows,

Value of boat = [tex]A (1 - r )^{t}[/tex]

By putting the value, we get

Value = [tex]36,000(1 - 0.15)^{5}[/tex]

= [tex]36,000(0.85)^{5}[/tex]

= 36,000 [tex]\times[/tex] 0.4437053125

= $15,973.4  or $15,973

You are given an expression for the volume of the rectangular prism. Determine an expression for the missing dimension.
V equal 4 x to the power of 3 plus 5 x to the power of 2 minus 32 x minus 33 and the dimensions are ( x + 1 ) and ( x + 3 ) .

Answers

Given:

The volume of the rectangular prism is

[tex]V=4x^3+5x^2-32x-33[/tex]

Two dimensions are (x+1) and (x+3).

To find:

The missing dimension.

Solution:

We know that, volume of a rectangular prism is

[tex]V=length\times breadth\times height[/tex]

It means, volume of a rectangular prism is the product of all dimensions.

We have,

[tex]V=4x^3+5x^2-32x-33[/tex]

Splitting the middle terms, we get

[tex]V=4x^3+4x^2+x^2+x-33x-33[/tex]

[tex]V=4x^2(x+1)+x(x+1)-33(x+1)[/tex]

[tex]V=(x+1)(4x^2+x-33)[/tex]

Splitting the middle term, we get

[tex]V=(x+1)(4x^2+12x-11x-33)[/tex]

[tex]V=(x+1)(4x(x+3)-11(x+3))[/tex]

[tex]V=(x+1)(x+3)(4x-11)[/tex]

So, the three dimensions of the rectangular prism are (x+1), (x+3) and (4x-11).

Therefore, the missing dimension is (4x-11).

Answer:

the missing dimension is (4x-11).

=> x² = 21² + 20²

=> x² = 441 + 400

=> x = √841

=> x = 29

Thus, the length of the unknown side is 29 units.

Answer:

3.112 because 56+56=112

Answer:

The answer is 4. 68

Step-by-step explanation:

since equal sides of triangle,it has equal angle at the base of triangle.So, the two angles of triangle at base is 56. The sum of angles in a triangle is 180.Therefore,56+56+x=180

x=180-112

Which is the best estimate of
11 1/5 and 2 3/4

Answers

I think your question lacks a little bit of information. After a little research, I am able to find that you probably wanted to say '11 1/5 divided by 2 3/4'.

Therefore, I am solving the question assuming that you want to say:

''What is the best estimate of 11 1/5 divided by 2 3/4''.

Answer:

The best estimate of  11 1/5 divided by 2 3/4 will be: 4

Step-by-step explanation:

Given the information

11 1/5 divided by 2 3/4

solving the expression

[tex]11\frac{1}{5}\div 2\frac{3}{4}[/tex]

[tex]\mathrm{Convert\:mixed\:numbers\:to\:improper\:fraction:}\:a\frac{b}{c}=\frac{a\cdot \:c+b}{c}[/tex]

so

[tex]11\frac{1}{5}=\frac{11\cdot 5+1}{5}=\frac{56}{5}[/tex][tex]2\frac{3}{4}=\frac{2\cdot 4+3}{4}=\frac{11}{4}[/tex]

so the expression becomes

[tex]11\frac{1}{5}\div 2\frac{3}{4}\:=\frac{56}{5}\div \:\frac{11}{4}[/tex]

                [tex]=\frac{56}{5}\times \frac{4}{11}[/tex]

                [tex]=\frac{56\times \:4}{5\times \:11}[/tex]

               [tex]=\frac{224}{5\times \:11}[/tex]

               [tex]=\frac{224}{55}[/tex]

                [tex]=4.07[/tex]

                [tex]= 4[/tex]       (Rounded to the nearest 1 or the Ones Place)

Therefore, the best estimate of  11 1/5 divided by 2 3/4 will be: 4

find the x-intercept and y -intercept 4x-7y=8​

Answers

Answer


X=2+7/4y

Y=-8/7+4/7x

Answer:

x- intercept = 2, y- intercept = - [tex]\frac{8}{7}[/tex]

Step-by-step explanation:

To find the x- intercept, let y = 0 in the equation and solve for x

4x - 7(0) = 8 , that is

4x = 8 ( divide both sides by 2 )

x = 2 ← x- intercept

To find the y- intercept , let x = 0 in the equation and solve for y

4(0) - 7y = 8, that is

- 7y = 8 ( divide both sides by - 7 )

y = - [tex]\frac{8}{7}[/tex] ← y- intercept

What is an equation in slope-intercept form of the line that passes through (6, 10) and is parallel to the graph of y=1/3x−1?
Here are the answer choices:
A: y−10=1/3(x−6)
B: y=1/3x+8
C: y−10=−3(x−6)
D: y=−3x+28

Answers

Answer:

B

Step-by-step explanation:

sope intercept form: (y=mx+b)

m = slope

m = 1/3 (slope of parallel lines are the same)

10 = 1/3(6)+b

10 = 2+b

b = 8

write with slope and b

y = 1/3x+8

A plane flies at 350 mph in the direction N 40° E with a wind blowing at 40 mph in the direction S 70° E. What is the plane’s drift angle?

5.89°
6.38°
45.89°
46.38°

Answers

Answer:

The correct option is;

5.89°

Step-by-step explanation:

The speed with which the plane flies = 350 mph

The direction of flight of the plane = N 40° E

The speed with which the wind blows = 40 mph

The direction in which the wind blows = S 70° E

Therefore, we have;

The resolution of the components of the motion of the plane, given as follows;

[tex]S_{Plane}[/tex] = 350 × sin(40°)·i + 350 × cos(40°)·j

The resolution of the components of the motion of the wind, given as follows;

[tex]S_{Wind}[/tex] = 40 × sin(70°)·i - 40 × cos(70°)·j

The resultant motion of the plane is given as follows;

[tex]R_{Plane}[/tex] = 262.563·i + 254.435·j

The direction of motion of the plane = tan⁻¹(262.563/254.435) ≈ N 45.9° E

Therefore, the plane's drift = Plane's Track - Plane's Heading  = N 45.9° E - N 40° E ≈ 5.9° ≈ 5.89°

Therefore, the correct option is 5.89°.

Answer:

5.89
