Answer:

To be able to determine the unknown range of the number with tolerance given, first we need to determine the 4% of 500. This can be done by multiplying 500 by the decimal equivalent of 4% which is equal to 0.04.

tolerance = (500) x (0.04) = 20

Lower limit: The lower limit is determined by subtracting 20 from 500.

Lower limit = 500 - 20 = 480

Upper limit: The upper limit is determined by adding 20 to the base value 500.

Upper limit = 500 + 20 = 520

The values, therefore, rang from 480 to 500.

<em>ANSWER: 480 - 520</em>

A pyramid shaped building is 311 feet tall and has a square base with sides of 619 ft. The sides of the building are made from r

zmey [24]

Answer:

Surface area of the reflective glass is 543234.4 square feet.

Step-by-step explanation:

Given that: height = 311 feet, sides of square base = 619 feet.

To determine the slant height, we have;

$l^{2}$ = $311^{2}$ + $309.5^{2}$

= 96721 + 95790.25

= 192511.25

⇒ l = $\sqrt{192511.25}$

= 438.761

The slant height, l is 438.8 feet.

Considering one reflecting surface of the pyramid, its area = $\frac{1}{2}$ × base × height

area = $\frac{1}{2}$ × 619 × 438.8

= 135808.6

= 135808.6 square feet

Since the pyramid has four reflective surfaces,

surface area of the reflective glass = 4 × 135808.6

= 543234.4 square feet

Select the correct answer.

vagabundo [1.1K]

Answer

D. `(y+4) = (5)/(3)(x+ 1)`

Step by step explanation

The given points are (-1, -4) and (2, 1)

Slope = (y2 - y1)/(x2 - x1)

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

= (1 + 4) / (2 +1)

m = 5/3

When two points are given, the equation of the line is

(y - y1) = m (x - x1)

y -(-4) = 5/3 (x - (-1))

y + 4 = 5/3 (x + 1)

The answer is (y+4) = (5)/(3)(x+ 1)

Thank you.

9) A heptagon has 6 exterior angles with measures of 47, 55, 62, 64, 54, and 49. What is the measure of the interior angle adjac

svetlana [45]

Answer:

seventh interior angle=∠x=29°

Step-by-step explanation:

sum of interior angle of polygon is equal to 360°

let seventh angle of heptagon is x

∠x+47°+55°+62°+64°+54°+49°=360°

∠x=360°-(47°+55°+62°+64°+54°+49°)

∠x=360°-331°=29°

∠x=29°

seventh interior angle=∠x=29° answer
