Solve x: -7y=2x+xy+10y

Step-by-step explanation:

the law of sine

a/sin(A) = b/sin(B) = c/sin(C)

where the sides and associated angles are always opposite to each other.

and the sum of all angles in a triangle are always 180°.

sin(90) = 1.

4.

there are multiple solutions, as the direction they are going has no relevance to their position to each other right now.

and the angles of depression can be forward or backwards of the plane.

the larger the angle of depression, the closer the ship is.

for the closer ship we get

height/sin(35) = ground distance / sin(180-90-35)

265/sin(35) = ground distance / sin(55)

ground distance (plane to closer ship) =

= 265×sin(55)/sin(35) = 378.4592218... m

for the farther ship we get

height/sin(25) = ground distance / sin(180-90-25)

265/sin(25) = ground distance / sin(65)

ground distance (plane to closer ship) =

= 265×sin(65)/sin(25) = 568.2943339... m

the distance of both ships is

568.2943339... - 378.4592218... = 189.8351121... m

now, this distance applies to the case, where both ships are on the same side of the plane.

if they are on different sides of the plane, then we need to add their individual distances from the plane to get the distance of both ships from each other :

568.2943339... + 378.4592218... = 946.7535557... m

5.

another right-angled triangle.

the string is the Hypotenuse (baseline).

the height and the ground distance are the legs.

so, we get

100/sin(90) = height/sin(52) = 100

= ground distance / sin(180-90-52)

height = 100×sin(52) = 78.80107536... m

ground distance = 100×sin(38) = 61.56614753... m

The true statement about the distribution of any variable model around the mean is (D) The distribution of the variable is the same shape as the distribution of its residual

From the question, we understand that the distribution of the model is based on its mean or average value.

The above means that the upper and the lower deviations are balanced.

Hence, the true statement about the distribution of any variable model around the mean is (D)

Answer:

833

Step-by-step explanation:

First find the 15% of 56,105;

[tex]\frac{15}{100}[/tex] * 56,105 = x

0.15 * 56,105 = x

882 = x

Now subtract 15% of 56,105 from 56,105;

15% of 56,105 = 882

now;

56,105 - 882 = 833

Step-by-step explanation:

the area of a square is simple its just a=length time width, so you just plug in youre length which is 14 and a square side are all the same size so the width is also 14, so your equation is a=14 times 14= 196. ;) hope that helped.

Answer:

Option A, [tex]385.0\ ft^2[/tex]

Step-by-step explanation:

Step 1:  Determine the area of the base

[tex]A = l * w[/tex]

[tex]A = 11\ ft * 11\ ft[/tex]

[tex]A = 121\ ft^2[/tex]

Step 2:  Determine the area of the triangles

[tex]A = \frac{h * b}{2}[/tex]

[tex]A = \frac{12\ ft * (11\ ft / 2)}{2}[/tex]

[tex]A = \frac{12\ ft * 5.5\ ft}{2}[/tex]

[tex]A = \frac{66\ ft^2}{2}[/tex]

[tex]A = 33\ ft^2[/tex]

There are two of these triangles per side which means that there are 8 of these triangles in total.  

[tex]33\ ft^2 * 8[/tex]

[tex]264\ ft^2[/tex]

Step 3:  Determine the surface area

[tex]SA = 121\ ft^2 + 264\ ft^2[/tex]

[tex]SA = 385\ ft^2[/tex]

Answer: Option A, [tex]385.0\ ft^2[/tex]

Answer:

Area = 144 ft^2

Step-by-step explanation:

Remark

Use the Pythagorean theorem to find the length of the legs. Then multiply them together and divide by 2.

Equations

a^2 + a^2 = c^2

Area = (1/2) * a^2

Givens

c = 24

Solution

Remember that an isosceles triangle has 2 equal sides. Both legs of the triangle are equal to a.

a^2 + a^2 = c^2              Combine

2a^2 = 24^2                   Expand

2a^2 = 576                    Divide by 2

2a^2/2= 576/2              

a^2 = 288                      You might just as well leave this. go to area

Area = 1/2 (288)

Answer:

The answer is 4cm.

Step-by-step explanation:

Given:

Height= 15cm

The volume of the Cylindrical bottle= 753.6

They have said to use π= 3.14

We are supposed to find r.

-------------------------------------------------------------

Volume of cylinder= πr²h

now substitute teh values given in the formula..we will get:

753.6 = 3.14× r²× 15

After u solve it , you will get

r²= 16

∴r = √16= 4cm

So,  the radius of the bottle is 4cm

Answer:

Milk Glass A can hold more milk.

Step-by-step explanation:

This problem mostly relies on the diameter of the milk glass.

To solve the problem, we'll find the volume of each glass as though it were a cylinder.

First, we start with the area of the base of each cylinder.

Using the formula [tex]\pi r^{2}[/tex], we can find the area of each base.

Note that r represents radius, which is half of the diameter, d.

The area of the base on Milk Glass A can be found with: [tex]\pi 1.75^2[/tex] which equals 9.62 inches squared.

The area of the base on Milk Glass B can be found with: [tex]\pi 0.75^2[/tex] which equals 1.77 inches squared.

Now that we have the area of each base, we just multiple the area by the height to get the full volume.

The volume of Milk Glass A can be found by multiplying [tex]9.62*4[/tex] which equals 38.48 cubic inches.

The volume of Milk Glass B can be found by multiplying [tex]1.77 *5[/tex] which equals 8.85 cubic inches.

Therefore, the larger answer of 38.48 cubic inches means Milk Glass A can hold more milk.
