Answer:

150 miles

Step-by-step explanation:

let m represent miles

$70 + .70m = $40 + .90m

subtract 40 from each side

$30 + .70m = .90m

subtract .70m from each side

$30 = .20m

divide both sides by .20

150 = m

Find x.
Vadim26 [7]

The value of x is 28 millimeters in the composite figure of two right-angled triangles lying next to each other

<h3>What is a composite figure?</h3>

A composite figure is a figure that is produced from the combination of two geometric shapes together.

The diagrammatic expression of a composite figure consists of two right-angled triangles lying next to each other can be seen in the image attached below.

For the left-side right-angled triangle, we have:

13² = h² + 5²

h² = 13² - 5²

h = √(169-25)

h = 12

Recall from the diagram that:

h² = pq

  • If p = 5 and q = x

∴

12² = 5x

x = 144/5

x ≅ 28 millimeters

Write the equation of a circle with center (-2, 0) and area = 64 pi
kozerog [31]

Answer:

The required equation in standard form is (x+2)^2+y^2=64

Step-by-step explanation:

The equation of a circle with center (h,k) an radius, r units is given by the formula;

(x-h)^2+(y-k)^2=r^2

The given circle has center (-2,0) and radius squared can be calculated from the given area, which is 64\pi

\pi r^2=64\pi

\implies r^2=64

We substitute these values into the formula to obtain;

(x--2)^2+(y-0)^2=64

We simplify to get;

(x+2)^2+y^2=64
