Step-by-step explanation:

\(\frac{4 \times 10^{-3}}{10^{-11}} \\=4 \times 10^{-3} \times 10^{11}\\=4 \times 10^{-3+11}\\=4 \times 10^8\)

Answer:

Step-by-step explanation:

Here the coefficients of the x terms in this quadratic are a = 15, b = 13 and c = 0.  The discriminant is b^2 - 4ac, or 13^2 - 4(15)(0) = 169 - 60, or 109.

The solutions are:

      -13 ± √109

x = -----------------

             30

Hence, the roots of the quadratic equation is

\(x=0,x=-\frac{13}{15}\)

What is the quadratic equation?

A quadratic equation is any equation that can be rearranged in standard form as + or offer insight into other areas of mathematics.

Here given equation is \(15x^2+13x=0\).

As the general formula is

\(x=\frac{-b+-\sqrt{b^2-4ac}}{2a}\\\\\)

Here, \(a=15,b=13\)

Substituting these values in general formula

\(x=\frac{-13+-\sqrt{(13)^2-4(15)(0)}}{2(15)}\\\\x=\frac{-13+-\sqrt{169-0}}{30}\\\\x=\frac{-13+-\sqrt{169}}{30}\\\\x=\frac{-13+-13}{30}\\\\\\x=\frac{-13-13}{30},x=\frac{-13+13}{30}\\\\x=\frac{-26}{30},x=0\\\\x=\frac{-13}{15},x=0\)

Hence, the roots of the quadratic equation is

\(x=0,x=-\frac{13}{15}\)

Answer:

Step-by-step explanation:

1) 4 1/2 x 2/3 (change the 4 1/2 to an improper fraction so it becomes 9/2)

Then it is 9/2 x 2/3 and you multiply across. The answer is 18/6 which is simplified to 3 cups.

2) 2/5 x 2 1/3 -> 2/5 x 7/3 = 14/15

3) 3 1/2 x 1 1/3 -> 7/2 x 4/3 = 28/6 = 4 4/6 = 4 2/3 ft tall

1) 5 / 1/3 When dividing with a fraction, you have to multiply by the reciprocal of the second fraction. So the 1/3 becomes 3/1 and now it is  5 x 3/1 which is 15/1. 15 muffins

2) 1/2 / 4 -> 1/2 x 1/4 = 1/8 of the original package

3) 8 / 1/4 -> 8 x 4/1 = 32/1 = 32 apple pieces

Answer:

60.8π square inches.

Step-by-step explanation:

The label is a rectangle that will be wrapped around a cylinder. So, the area of the label can be found by multiplying the height of the rectangle by the circumference of the cylinder. The circumference of the cylinder can be found by multiplying the diameter by π. Since the two circles in the figure represent the top and bottom faces of the cylinder, the diameter is 2 × 4 = 8 inches. Therefore, the circumference of the cylinder is 8π inches. Thus, the area of the label is:

7.6 × 8π = 60.8π square inches

Therefore, the label is 60.8π square inches.

Answer:

60.8π square inches

Step-by-step explanation:

Chain of thought reasoning: 1. The label is represented by the rectangle in the figure.

2. The area of a rectangle is equal to the width multiplied by the height or A = w x h.

3. The width of the rectangle is equal to the circumference of the circles.

4. The circumference of a circle is equal to 2πr, where r is the radius of the circle.

5. Therefore, the width of the rectangle is equal to 2π x 4 = 8π inches.

6. The height of the rectangle is 7.6 inches.

7. Therefore, the area of the rectangle is equal to 8π x 7.6 = 60.8π square inches.

Answer:

Step-by-step explanation:Situation A: The hang glider descended 33.57 feet and again ascended 14.98. So 33.57 - 14.98 = 18.58. So now the hang glider is at 18.58 feet

Situation B: Initially they gained 7 2/5 yards and then lost 3/5 yards.

7 2/5 yards can be written as 37/5. As they lost 3/5 yards, 37/5 - 3/5 = 34/5. So the remaining yards are 34/5 yards.

Situation C: Hiker walked 3 1/6 miles and then 2 1/2 miles. So the total distance is 3 1/6 + 2 1/2 = 5 4/6 miles.

Situation D: Total amount earned is $23.66 + $15.84 = $39.5.

Answer:

0.32 km

Step-by-step explanation:

Using the formula r = c / (2 * π), where c = 2 kilometers and π = 3.14, we can calculate the radius as:

r = 2 km / (2 * 3.14)

r = 2 km / 6.28

r = 0.31847133758 km

Rounding this to the nearest hundredth gives:r ≈ 0.32 km

Therefore, the approximate radius of the circle is 0.32 kilometers.

Answer:

192 hours per day / 8 hours per person per day = 24 people

Step-by-step explanation:

Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:

720 person-days x 8 hours = 5,760 hours

To complete the project in 30 days, the total number of hours needed per day is:

5,760 hours / 30 days = 192 hours per day

Answer:

2.  200.52    4. 212.67       5. 148.48

Step-by-step explanation:

for (2) you find the area of each shape first the square

12*12=144

then you find the area of the semicircle

the formula is A= (3.14)r^2/2

the (r) is 6 because that is half of the whole side of the semicircle

so... (3.14) 6^2/2

6*6= 36

(3.14)36/2

113.04/2

56.52

then add the 144 from the square to it

56.52+144

200.52

-85.5 (area of the triangle)

-127.17 (area of the semicircle)
