Answer:

[tex]\mathrm{D.\:}\sqrt{126}[/tex]

Step-by-step explanation:

All three triangles in the figure are similar. Therefore, we can set up the following proportion:

[tex]\frac{18}{m}=\frac{m}{7}[/tex]

Cross-multiply to solve:

[tex]m^2=18\cdot 7 = 126, \\\\m=\fbox{$\sqrt{126}$}[/tex].

Answer:

The answer is D because, John is gonna keep running the multiples of 8.

Step-by-step explanation:

8X2= 16

First, find the slope using the equation, y2 - y1 / x2 - x1

1-5 / 4 - - 4 = -4/8 =  -1/2

plug this into slope intercept form

y = -1/2x + b

Next use one of the points to find b using point-slope form. I will use (4,1)

y - y1 = m ( x - x1)

y - 1 = -1/2 (x - 4)

y -1 = -1/2x + 2

+1                  +1

y = -1/2x + 3 is your equation

Answer:

The coordinates of the cross on the scale drawing which locates where Kim can plant the tree is (3.45 cm, 0.58 cm)

Step-by-step explanation:

The question relates to coordinates geometry and the solution can be obtained graphically by construction as shown in the attached drawing

The given parameters of the scale drawing are;

The scale of the drawing is 1 cm = 2 m

The dimensions of the rectangle representing the garden in the scale drawing is given as follows;

The width of the rectangle = 2.5 cm

The length of the rectangle = 4 cm

The required location where the tree is to be planted = 7 m from A and 4 m from point C

Therefore, the location where Kim can plant the tree on the scale drawing is 3.5 cm from point A and 2 cm from point C

Taking the coordinate of point A as the origin, we have;

The coordinates of point A = (0, 0)

∴ The coordinates of point C = (4, 2.5)

The general equation of a circle is (x - h)² + (y - k)² = r²

Where, (h, k) is the coordinate of the center of the circle

The location of the point is on a radius 3.5 cm from point A and a radius 2 cm from point C

Therefore, for point A, we have;

(x - 0)² + (y - 0)² = 3.5²

x² + y² = 12.25...(1)

For point C, we have;

(x - 4)² + (y - 2.5)² = 2² = 4

Which gives;

x² - 8·x + 16 + y² - 5·y + 6.25 = 4

x² + y² - 8·x - 5·y + 22.25 = 4

We have x² + y² = 12.25 from equation (1), therefore, we have;

12.25 - 8·x - 5·y + 22.25 = 4

- 8·x - 5·y = 4 - 22.25 - 12.25 = -30.5

∴ 8·x + 5·y = 30.5

y = (30.5 - 8·x)/5

Therefore, we have;

x² + y² = 12.25 = x² + ((30.5 - 8·x)/5)² = 12.25

Using a graphing calculator we get;

356·x² - 1952·x + 2496 = 0

Which gives;

x = (1952 ± √((-1952)² - 4×356×2496))/(2 × 356)

x = 3.452197227 or 2.03094884081

To two decimal places, we have the coordinates of the points where the tree can be planted given as follows;

Therefore, y = (30.5 - 8×3.452197227)/5 = 0.5764844368

or y = (30.5 - 8×2.03094884081)/5 = 2.8504818547

y = 0.5764844368 or 2.8504818547

To two decimal places, we have the coordinates of the places where Kim can plant the tree are given as follows;

(3.45, 0.58) or (2.03, 2.85)

We note that the point (2.03, 2.85) is at the outside the drawing the area as 2.85 cm is more than 2.5 cm which is the width (height) of the rectangle as shown in the attached drawing created with Microsoft Word.

Therefore, the coordinates of the cross where Kim can plant the tree is (3.45, 0.58)

Answer: a) 1800g b) 300g c) 1200g

Step-by-step explanation:

a) 1.8 x 1000 = 1800g

b) 1800g / 6 toys= 300g > the weight of one toy

c) 300g x 4 toys = 1200g / 1000 = 1.2 kg

Answer:

a. 1.8kg to grams

1000g =1kg

x =1.8kg

cross multiply

x = 1.8 x 1000

x= 1800g

b. weight of one toy

6 toys = 1800g

1 toy = 1800÷6

1 toy = 300g

c. 1kg = 300g

4toys = x

x = 4 x 300

x = 1200g

1200g to kilogram

1000g = 1kg

1200g = x

cross multiply

1000x = 1200

x = 1200÷1000

x = 1.2kg

Answer:

x = 24

Step-by-step explanation:

3x - 2y = 18

y = 27

3x - 2(27) = 18

3x - 54 = 18

3x = 72

x = 24

Answer:

x=24

Step-by-step explanation:

3x-2y=18

Put the y value where it belongs...

3x-2(27)=18

3x-54=18        Separate the x

    +54  +54

3x=72         Divide

Answer: The independent variable = x which represent the the number of hours taken to complete the job.

Step-by-step explanation:

In the given function: y = 50 + 65x, x = Number of hours, y = Total cost of the job.

Here, total  cost of the job depends on the number of hours.

So the independent variable = x which represent the the number of hours taken to complete the job.

Answer:

[tex]r=9.0\:\mathrm{cm}[/tex]

Step-by-step explanation:

The volume of a sphere is given as [tex]\frac{4}{3}r^3\pi[/tex]. Therefore we have the following equation:

[tex]\frac{4}{3}r^3\pi=3026,\\r^3=\frac{3}{4}\cdot\frac{3026}{\pi},\\r^3=722.40428,\\r=\sqrt[3]{722.40428},\\r\approx \fbox{$9.0\:\mathrm{cm}$}[/tex].

Rounding this to the nearest tenth of a centimeter, the radius of the sphere is approximately 14.0 cm.

Volume refers to the amount of space occupied by an object or substance. In mathematics, it is usually measured in cubic units (e.g. cubic meters, cubic centimeters).

The volume of an object can be calculated using its dimensions and specific formulas that depend on the shape of the object.

For example, the volume of a cube is calculated by multiplying its length, width, and height, while the volume of a sphere is calculated using the formula [tex](4/3)\pi r^3[/tex], where r is the radius of the sphere.

The formula for the volume of a sphere is V = (4/3)πr³, where r is the radius of the sphere and π (pi) is a mathematical constant approximately equal to 3.14159.

We can rearrange this formula to solve for r:

r = [tex](3V/4\pi)^{(1/3)[/tex]

Substituting the given volume V = 3026 [tex]cm^3[/tex], we get:

r = [tex](3(3026)/(4\pi))^{(1/3)[/tex] ≈ 14.0 cm

Thus, the radius of the sphere is approximately 14.0 cm, rounded to the nearest tenth of a centimetre.

Step-by-step explanation:

we know he has 3000 miles to travel so if he travels 600 mph than you would have to divide.

another way you could solve it is to take two zeros from each point so that you have 30 and 6, then you divide then.

30/6 = 5
