Answer:

7 x 10^{-2}

Step-by-step explanation:

1. Estimate 0.067238149 to the nearest hundredth.

In the decimal 0.067238149, 6 is in the hundredth position. So round decimal to 0.07, since the 7 in the original decimal 0.067238149, which is in the thousandths position, is 5 or more.

2, Express your answer as a single digit times a power of ten.

0.07 becomes 7.

Then, to get the power of ten, in the original decimal 0.067238149, place an imaginary decimal between the 6 and 7. Next, count to the left to find out how many places there are to the original decimal.  There are 2 spaces.

Therefore, the answer is 7 x 10^{-2} .

\angle BAD=100^{\circ} (opposite angles in a parallelogram)

\angle EAD=80^{\circ} (subtraction)

\angle ADE=65^{\circ} (angles in a triangle add to 180 degrees)

\angle CDA=80^{\circ} (adjacent angles in a parallelogram are supplementary)

\boxed{\angle CDE=15^{\circ}} (subtraction)

\angle CED=65^{\circ} (angles in a triangle add to 180 degrees)

Elisondra is eating at a restraurant with three friends. They want to choose at random who will order first. If you model the si
trapecia [35]

An equal-sized spinner is used to model probabilities

The spinner should have 4 equal sections

The number of friends is given as:

\mathbf{Friends = 3}

When Elisondra is included, the total number of people that went to the restaurant is:

\mathbf{n = Friends + 1}

Substitute 3 for Friends

\mathbf{n = 3 + 1}

Add 3 and 1

\mathbf{n = 4}

The number of people that went to the restaurant is the number of equal sections of the spinner.

Hence, the spinner should have 4 equal sections

Identify the equation of the circle that has its center at (16, 30) and passes through the origin
Veronika [31]

To solve this question, we have to find the equation of the circle with given center and where it passes. Doing this, we get that the equation of the circle is:

(x - 16)^2 + (y - 30)^2 = 1156

Equation of a circle:

The equation of a circle with center (x_0, y_0) and radius r is given by:

(x - x_0)^2 + (y - y_0)^2 = r^2

Center at (16, 30)

This means that x_0 = 16, y_0 = 30

Thus

(x - 16)^2 + (y - 30)^2 = r^2

Passes through the origin:

We use this to find the radius squared, as this means that x = 0, y = 0 is part of the circle. Thus

(x - 16)^2 + (y - 30)^2 = r^2

(0 - 16)^2 + (0 - 30)^2 = r^2

r^2 = 16^2 + 30^2 = 1156

Thus, the equation of the circle is:

(x - 16)^2 + (y - 30)^2 = 1156

For another example to find the equation of a circle, you can look at brainly.com/question/23719612
