Answer:

A system of two linear equations can have one solution, an infinite number of solutions, or no solution. Systems of equations can be classified by the number of solutions. If a system has at least one solution, it is said to be consistent . If a consistent system has exactly one solution, it is independent .

According to the Americans with Disabilities Act, a ramp can rise no more than 1 ft for every 12 ft of horizontal distance. What

taurus [48]

Answer:

A. 4.8°

Step-by-step explanation:

We have that,

The horizontal distance for the ramp = 12 feet.

Maximum height of the ramp = 1 feet.

So, we get that the value of the angle 'x' made by the ramp with the ground is given by,

$\tan x=\frac{perpendicular}{base}$

i.e. $\tan x=\frac{1}{12}$

i.e. $\tan x=0.0833$

i.e. $x=\arctan 0.0833$

i.e. x = 4.8°

Thus, the maximum angle made by the ramp with the ground is 4.8°.

Find the surface area of a cylinder with a base radius of 2 cm and a height of 8 cm

gtnhenbr [62]

Answer:

82.6cm2

Step-by-step explanation:

$\pi {r}^{2} + \pi {r}^{2} + 2 \pi \: r h$

$\pi = \frac{22}{7}$

radius =2cm

height=8cm

$( \frac{22}{7} \times 2 \times 2 )+ ( \frac{22}{7} \times 2 \times 2) + (2 \times \frac{22}{7} \times 2 \times 8)$

Multiplying the numerators and The whole numbers, we have

$\frac{88}{7} + \frac{88}{7} + \frac{402}{7}$

Since the denominators of the fractions are the same, we add the numerators.

$\frac{88 + 88 + 402}{7} = \frac{578}{7} \\ which \: becomes \\$

$82.57{cm}^{2} = 82.6 {cm}^{2}$

<h3>Solution(s):</h3>

<u>1)</u><u> What distance did a car travel that went 70 mph for 6 hours?</u>

Given:

70 miles = 1 hour

<u>Multiply the RHS by 6 to see what distance was covered by the car in 6 hours.</u>

70 miles = 1 hour
=> 70 x 6 miles = 6 hours
=> 420 miles = 6 hours

The car traveled 420 miles in 6 hours.

<u>2)</u><u> What is the perimeter of a rectangle with a length of 7 cm and a width of 4 cm?</u>

Given:

Length: 7 cm
Breadth: 4 cm

Formula to find perimeter: 2(L) + 2(B)

<u>Substitute the values into the formula to find the perimeter.</u>

2(L) + 2(B)
=> 2(7) + 2(4)
=> 14 + 8
=> 22 cm

The perimeter of the rectangle is 22 cm.
