Morgarella [4.7K]

Answer:

The formula for calculating the circumference of a circle is 2*pi*r. Because pi does not have an end, we'll use 3.14, since that is the approximate value of pi.

2*6*3.14 = 37.68

The outer rim of the pool is about 37.68 meters long

Step-by-step explanation:

It’s probably 40 because it says about how long not exactly.

Answer:

height for the building = 551.8 ft

Step-by-step explanation:

The info given describes the shape of a right triangle.

Thus:

Reference angle = Angle of elevation = 23°

Opposite side = height of the building = ?

Adjacent side = 1,300 ft

Apply trigonometric function, TOA:

Tan 23 = Opp/Adj

Tan 23 = Opp/1,300

1,300 × Tan 23 = Opp

551.817261 = Opp

Opp ≈ 551.8 ft

height for the building = 551.8 ft

Find the following when a = -1, b = 2, c = -1/4<br> (4b - 3)/(2a) -1

Katena32 [7]

We substitute the given into the equation
given: a=-1, b=2, c= $\frac{-1}{4}$
=( $\frac{4b-3}{2a}$ -1
= $\frac{4(2)-3}{2(-1)}$ -1
= $\frac{8-3}{-2}$ -1
= $\frac{5}{-2}$ -1
to continue, we can either find a common denominator or change the fraction to decimal.
Fraction to Decimal:
$\frac{5}{-2}$ =-2.5
Equation=-2.5-1=-3.5
OR Common Denominator:
= $\frac{5}{-2}$ $\frac{-1}{1}$ × $\frac{-2}{-2}$ (denominator should be -2=common)
= $\frac{5}{-2}$ + $\frac{2}{-2}$
= $\frac{7}{-2}$
which also = to -3.5

Scrat [10]

Answer:

$10$

Step-by-step explanation:

The lines surrounding 10 are called positive brackets, meaning the no matter what number is in those brackets, it will always come out of positive.

There is nothing to do with just 10 because we don't need to change anything.

|10| simplified is 10
