Answer:

The answer is option C

Step-by-step explanation:

Since the triangle is a right angled triangle we can use trigonometric ratios to find x and y

In order to find x we use tan

tan∅ = opposite/ adjacent

From the question

The opposite is 4

The adjacent is x

Substitute the values into the above formula

That's

We have the answer as

In order to find y we use sine

sin ∅ = opposite / hypotenuse

From the question

The opposite is 4

The hypotenuse is y

So we have

We have the answer as

Answer:

160 m

Step-by-step explanation:

you can approach this question with the thinking of simple math. First, you have the value of -85 rose by 30 means +30 and descending 105 means -105.

So, the calculation you will get is -85+30-105=-160. The negative means going down as the direction.

Answer:

2a). Height = 2 cm

2b). Surface area = 395.84 cm²

Step-by-step explanation:

2a). Volume of the cylinder = 308 cm³

      Radius of the base of the cylinder = 7 cm

      Formula to get the volume of a cylinder = πr²h

     308 = π(7)²h

     h = [tex]\frac{308}{49\pi }[/tex]

     h = 2 cm

     Therefore, height of the cylinder will be 2 cm.

2b). Formula to calculate the surface area of the cylinder = [tex]2\pi r(r + h)[/tex]

      By substituting the values in the given formula,

      S.A. = 2π(7)(7 + 2)

              = 395.84 cm²

     Therefore, Surface area of the cylinder is 395.84 cm².

Answer:

The correct option is;

W

Step-by-step explanation:

The number of points that defines a plane in a Euclidean space in all dimensions is either three points which are not on the same line, or two colinear points and a third point not on the line

The given points of the plane are UVX, which gives the plane as being diagonal to the cube and perpendicular to the side face of the cube.

The fourth point in plane UVX is therefore W.

Answer:

correct answer is x = 2.75

Step-by-step explanation:

Given;

AB = 2x-5

BC = 6x

AC = 27

Hence,

=> AC = AB + BC

=> 27 = 2x-5 + 6x

=> 27 = 8x-5

=> 27-5 = 8x

=> 22 = 8x

=> 22/8 = x

=> 11/4 = x

or

2.75 = x

Answer:

It will take 19 days from Sunday.

Step-by-step explanation:

You can use the equation 172 + 6d = 1 + 15d for this equation. 172 and 1 are how many items Jose and Biruk started with. 6d and 15d represent how many items they get a day. Here's how you can solve the equation:

172 + 6d = 1 + 15d

       -6d         -6d

        172 = 1 + 9d

           -1   -1

         171 = 9d

          ÷9    ÷9

          19 = d   (write it as d = 19)

11x - 55 - 5a + ax

11 (x - 5) - a ( 5 + x )

Answer:

11 (x - 5) - a ( 5 + x )

Answer:

The Break Even point is the point at which the cost=revenue   14,980+20x=30x 14,980=10x 1,498=x   a. 1,498 units must be sold to break even. At $20 per unit, the dollar amount will be $29,960   b. The profit function is P(x)=R(x)-C(x) So P(x)=30x-(14,980+20x) If you want to solve for this equation just enter the value of x we found for the break even point to get the answer.

The profit for 90 downloads will be;

⇒ P = $223

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Your revenue for x downloads is given by,

⇒ f(x) = 3x

And, Your profit is $20 less than 90% of the revenue for x downloads create a function p to model the profit.

Now,

Since, Your revenue for x downloads is given by,

⇒ f(x) = 3x

And, Your profit is $20 less than 90% of the revenue for x downloads create a function p to model the profit.

Hence, We can formulate;

⇒ P = 90% of f (x) - 20

⇒ P = 90/100 × 3x - 20

⇒ P = 270x/100 - 20

⇒ P = 2.7x - 20

So, The profit for 90 downloads​ will be;

⇒ P = 2.7 × 90 - 20

⇒ P = $223

Thus, The profit for 90 downloads = $223

Answer:     a) $481.62      b) $16,569.76

Step-by-step explanation:

The formula for compound interest is:    [tex]A = P(1 + r)^t[/tex]     where

Given: P = 3000, r = 1.15% (0.015), t = 10

[tex]A = 3000(1 + 0.015)^{10}\\\\\\A = 3000(1.015)^{10}\\\\\\A = 3,481.62[/tex]

Interest Earned = accrued amount - principle

                          = 3,481.62 - 3,000

Answer:

360

Step-by-step explanation:

First, we need to solve the numbers in the parentheses.

(14-2)^2 = (14 - 2)(14 - 2) = 196 -56 +4 = 144 (Use FOIL)

Then, we multiply that by 5.

144 * 5 = 720

Finally, we divide by two to get our answer.

720 ÷ 2 = 360

Answer:

360.

Step-by-step explanation:

Step 1:

Combine and Determine sums of certain numbers: 12 = 22•3

(12)2 = (22•3)2 = 24 • 32 =

--5 • (24•32) /2

Step 2:

Simplify: 24•32) /2 =

--5 • 72

Step-by-step explanation:

We know that the area of a circle in terms of π will be πr². However the area with respect to the diameter will be a different story. The first step here is to find a function relating the area and diameter of any circle --- ( 1 )

For any circle the diameter is 2 times the radius,

d = 2r

Therefore r = d / 2, which gives us the following formula through substitution.

A = π(d / 2)² = πd² / 4

Hence the area of a circle as the function of it's diameter is A = πd² / 4. You can also say f(d) = πd² / 4.

Now we can substitute " d " as 4, solving for the area ( A ) or f(4) --- ( 2 )

f(4) = π(4)² / 4 = 16π / 4 = 4π - This makes the area of circle present with a diameter of 4 inches, 4π.

Answer:

£13

Step-by-step explanation:

Set up a system of equations where s represents the cost of one shirt and j represents the cost of one jumper:

2s + j = 29

s + j = 21

Multiply the bottom equation by -2 to solve by elimination by cancelling out the s variables:

2s + j = 29

-2s - 2j = -42

-j = -13

j = 13

One jumper will cost £13

Ratio of triangle = 3 : 4

Step-by-step explanation:

Given:

Parallel sides = 9 cm , 12 cm

Find:

Ratio of triangle

Computation:

Assume height = h

Area of triangle = [1/2]bh

Area of triangle (1) = [1/2](9)h

Area of triangle (1) = 4.5 h

Area of triangle (2) = [1/2](12)h

Area of triangle (2) = 6 h

Ratio of triangle = 4.5 h / 6 h

Ratio of triangle = 3 : 4
