velikii [3]

Answer:

shorter piece: 2 feet

longer piece: 8 feet

Step-by-step explanation:

let the shorter piece be x

then the longer piece will be 3x + 2

<u>if they join together</u>:

  • 3x + 2 + x = 10
  • 4x + 2 = 10
  • 4x = 10 -2
  • 4x = 8
  • x = 2

<u>Longer piece</u>:

  • 3x + 2
  • 3(2)+2
  • 8 feet

The altitude of a triangle is increasing at a rate of 3 centimeters/minute while the area of the triangle is increasing at a rat
sp2606 [1]

The base of the triangle is decreasing at a rate of 3.60 centimeters/minute.

According to the statement

we have to find that the rate at which the base of triangle changing.

So, For this purpose,

Area of triangle: A = (1/2)(b * h)

Related Rates - Derivative with respect to time:

(d/dt)[A = (1/2)(b * h)]

Then

dA/dt = (1/2)[b * dh/dt + h * db/dt]

Given: h = 11 centimeters, A = 91 square centimeters, b = ??

A = (1/2)(b * h)

Then it becomes

b = 2A/h

substitute the value then

b = 2(91)/11

b = 16.54 centimeters

Then

h = 11 centimeters, b = 16.54 centimeters, dA/dt = 5 square centimeters/minute, dh/dt = 3 centimeters/minute, db/dt = ?? centimeters/minute

So,

(d/dt)[A = (1/2)(b * h)]

Then it become

dA/dt = (1/2)[b * dh/dt + h * db/dt]

5= (1/2)[16.54 * 3 + 11 * db/dt]

5= 49.62/2 + 11/2 * db/dt

11/2 * db/dt = 5- 49.62/2

5.5*db/dt = 5 - 24.81

db/dt = -19.81/5.5

db/dt = -3.60 centimeters/minute

So, The base of the triangle is decreasing at a rate of 3.60 centimeters/minute.

The size of the angles of a quadrilateral are in the ratio
Irina-Kira [14]

Answer:

40°, 80°, 120°, 120°

Step-by-step explanation:

sum the parts of the ratio, 1 + 2 + 3 + 3 = 9 parts

The sum of the interior angles of a quadrilateral is 360°

Divide this by 9 to find the value of one part of the ratio.

360° ÷ 9 = 40° ← value of 1 part of the ratio

Then

2 parts = 2 × 40° = 80°

3 parts = 3 × 40° = 120°

The 4 angles are 40°, 80°, 120°, 120°
