Answer:

A straight angle changes the direction you are pointing in. A straight angle looks like a straight line. It has an angle measurement of 180 degrees. Straight angles can be composed of several angles, as long as the angles add up to 180 degrees.

Simplify and express the result in power notation with positive exponent
Molodets [167]

Answer:

3²

Step-by-step explanation:

Given expression:

\sf (3^{-3} \div 3^{-10}) \times 3^{-5}

Following the <u>order of operations</u>, carry out the calculations inside the parentheses first.

\textsf{Apply the quotient exponent rule} \quad a^b \div a^c=a^{b-c}:

\implies \sf 3^{-3-(-10)} \times 3^{-5}

\implies \sf 3^{-3+10} \times 3^{-5}

\implies \sf 3^{7} \times 3^{-5}

\textsf{Apply the product exponent rule} \quad a^b \times a^c=a^{b+c}:

\sf \implies 3^{7+(-5)}

\sf \implies 3^{7-5}

\sf \implies 3^2

Calculate the noon sun angles for new orleans, usa and helsinki, finland on september 22. in the answer below, new orleans answe
Otrada [13]
<span>We need to calculate noon sun angle. Noon sun angle is an angle at which sun-rays fall at noon on a given date.
</span>On September 22, the sun’s rays form a 90° angle at noon at the equator.

Formula for calculating noon sun angle is:

Noon_sun_angle = 90° - Zenith angle

We have complementary angles so we need to substract zenith angle from 90°.

The zenith angle is the distance between subsolar point (point where sun is at 90°) and the latitude of an observer. In our case this angle will have same value as latitude because subsolar point is at equator 0°. If our latitude and subsolar point are at same hemisphere we substract values. Otherwise we add values.

New Orleans, USA
Latitude = 30°
Noon_sun_angle = 90° - 30° = 60°

Helsinki, Finland
Latitude = 60°
Noon_sun_angle = 90° - 60° = 30°

Thepotemich [5.8K]
Answer: 46

Explanation: If Mia is paid $55 for every bicycle, she would need to fix up/sell 46 bicycles. This is because 45 x 55 = 2475 and Mia wants over 2500 but 46 x 55 = 2530. Therefore, 46 is the minimum number of bicycles.
