The ratio of the lengths of corresponding parts in two similar solids is 5:1,

vlabodo [156]

The ratio of the surface areas of two similar solids can be computed by squaring the given ratio of the corresponding sides. For this given,
r = (5:1)^1
r = 25:1

Thus, the ratio of the surface areas of the similar solids is 25:1.

15. JAGUARUNDI A jaguarundi springs from a fence post to swat at a low flying bird.

sukhopar [10]

Answer:

The discriminant, -14.71 < 0, shows that there is no solution of the equation, h = -16·t² + 22.3·t + 2, at the line 'h = 10' feet, therefore, the Jaguarundi height as she springs will not be up to 10 feet and therefore she will not reach the bird

Step-by-step explanation:

From the question, the equation that models the Jaguarundi's height, 'h', ma be written approximately as follows;

h = -16·t² + 22.3·t + 2

Where;

t = The time (duration) in seconds

The discriminant of the equation a·x² + b·x + c = 0 is b² - 4·a·c

When h = 10, we have;

10 = -16·t² + 22.3·t + 2

∴ 0 = -16·t² + 22.3·t + 2 - 10 = -16·t² + 22.3·t - 8

The discriminant of the given quadratic equation is given as follows;

The discriminant = 22.3² - 4 × (-16 × (-8)) = -14.71 < 0

Therefore, the function, h = -16·t² + 22.3·t + 2 has no real root at h = 10

The parabola does not reach or pass through the line h = 10 which is the height at which the bird is flying.

The Jaguarundi will not reach the bird flying at the height of 10 feet.

There are about 30.2 million small businesses in the u.s and about 30,000 other larger businesses. What percent of all businesse

Leni [432]

<h3>Answer:</h3>

99.90%

<h3>Step-by-step explanation:</h3>

STEPS:

Find the total amount
Find out what number of what we want to know the percentage of there are out of the whole amount there is. (Divide the percentage amount we want to find by the total amount)
Turn into a percentage by multiplying by 100

Find the total sum

30.2 mil = 30,200,000 small businesses + 30,000 other = 30,230,000 total

Find the fraction that small businesses make up of the total

$\frac{small~businesses}{total~businesses} = \frac{30,200,000}{30,230,000} = 0.9990$

Convert to percentage

0.9990 → % = 0.9990 × 100 = 99.90%

Hope this helps,
