Answer:

106 sq.meters

Step-by-step explanation:

Hi! Here is your step by step explanation, if you have any questions, feel free to comment back to me and I'll help you out! I hope this helps, please leave a brainly if you can!

You want to break this shape up into 3.

First, multiply the longest side. DO NOT do 10x12, do 10x5, since the side of that rectangle is 5, not 12 (12 is the whole shape). Then, do 4 by 7 twice, since the shorter sides have those dimensions. Then add that up to get...

2(7x4)= 56

10x5=50

50+56=106

Earth rotates on an axis through its poles. The distance from the axis to a location on Earth at 40 degrees north latitude is ab

murzikaleks [220]

Answer: v = 793.77 mph

Step-by-step explanation: Linear speed of a circular movement is calculated by using the formula:

v = ω.r

where

ω is angular velocity

r is radius of the path

Angular velocity is the rate of change of the angular position of an object with respect of time, i.e., is how fast an object changes its angular position with time:

$\omega = \frac{d \theta}{dt}$

$\omega = \frac{2\pi}{time}$

The Earth takes 24 hours to complete a rotation, then angular velocity:

$\omega = \frac{2\pi}{24}$

$\omega =$ 0.262 rad/h

At a location 40° north, radius is 3033.5 miles, so:

v = 0.262*3033.5

v = 793.77

At latitude of 40°north, linear speed is 793.77mph.

MT is a diameter of OE. Calculate the measure of AT.

USPshnik [31]

Answer:

C. 96°

Step-by-step explanation:

m<AME = 48° is an inscribed angle

Arc AT = intercepts arc

Based on the inscribed angles theorem, we have:

m<AME = ½(arc AT)

48° = ½(arc AT)

Multiply both sides by 2

48° × 2 = ½(arc AT) × 2

96° = arc AT

Arc AT = 96°

Write 9.4*10^7 a. in standard notation b. write out the name of this number

Vitek1552 [10]

Answer:

a. 94,000,000

b. Ninety-four million

Step-by-step explanation:

In order to find this number, move the decimal place to the right by the number in the exponent. Since the exponent is 7, we move it to the right of the 4 (that's one move), then we have six more moves. So we add six zeroes to the end of the number.

94,000,000

Find the measure of angle B.

Elza [17]

Answer:

The measure of angle B is 122° ⇒ answer D

Step-by-step explanation:

* Lets explain how to solve the problem

- The sum of interior angles of any polygon can found by using this

rule (n - 2) × 180° , where n is the number of the sides or angles

of the polygon

∵ ABCDEFG is a polygon of 7 sides

∴ The sum of the measures of the interior angles = (7 - 2) × 180°

∴ The sum of the measures of the interior angles = 900°

∵ m∠A = 12x - 9 , m∠B = 9x + 14 , m∠C = 133° , m∠D = 10x + 9

∵ m∠E = 10x , m∠F = 136° , m∠G = 10x + 5

∵ The sum of all angles = 900°

∴ 12x - 9 + 9x + 14 + 133 + 10x + 9 + 10x + 136 + 10x + 5 = 900

∴ 51x + 288 = 900

- Subtract 288 from both sides

∴ 51x = 612

- Divide both sides by 51

∴ x = 12

∵ m∠B = 9x + 14

∵ x = 12

∴ m∠B = 9(12) + 14 = 122°

* The measure of angle B is 122°
