A round crafts table has a diameter of 36in how much plastic laminate is needed to cover the top of the table?

Perform the indicated computation. Write the answer in scientific notation. 12x10^4\3x10^−2

Paul [167]

Let us consider the given expression:

$\frac{12 \times 10^{4}}{3 \times 10^{-2}}$ in the scientific notation.

= $\frac{12 \times 10^{4} \times 10^{2}}{3 }$

[Using the law of exponents, which states

$a^{m} \times a^{n} = a^{m+n}$ ]

= $\frac{12 \times 10^{6}}{3}$

On dividing, we get

= $4 \times 10^{6}$

Hence, it is the required scientific notation of the given expression.

Write an equation for each question, please! (t = years after 1960)

VashaNatasha [74]

Answer:

1) y = - 0.54(25)

2) 0.4 = 98 - 0.54t

3) 0.6 = 2 + 0.54t

4) 98 - 0.54t = 2(2 + 0.54t)

(you asked for equations, so I think these are the equations you are looking for!)

Step-by-step explanation:

1)

(given) y = 98 - 0.54t

(plugging in years after 1960) y = - 0.54(25)

2)

(given) y = 98 - 0.54t

(changing percent to decimal) 40% = 0.4

(plugging in percentage) 0.4 = 98 - 0.54t

3)

(given) y = 2 + 0.54t

(changing percent to decimal) 60% = 0.6

(plugging in percentage) 0.6 = 2 + 0.54t

4)

(given)

(male) y = 98 - 0.54t

(female) y = 2 + 0.54t

(setting up the equation so male is 2 times the percent of female)

98 - 0.54t = 2(2 + 0.54t)

A navel distress signal flag is in the shape of a triangle. Two of the three angles measure 55 degrees each. What is the measure

Alekssandra [29.7K]

The measure of third angle is 70 degree

<h3>Solution:</h3>

Given that, a navel distress signal flag is in the shape of a triangle

Two of the three angles measure 55 degrees each

We know that there are three angles in triangle

The angle sum property of a triangle states that the angles of a triangle always add up to 180°

Every triangle has three angles and whether it is an acute, obtuse, or right triangle, the angles sum to 180°

Let three angles be "A", "B", "C"

Given that two angles measure 55 degrees each. Let say angle A = angle B = 55

By angle sum property of triangle,

Angle A + angle B + angle C = 180 degree

55 + 55 + angle C = 180

110 + angle C = 180

angle C = 180 - 110 = 70 degree

Thus the measure of third angle is 70 degree
