The correct answer is : 340 cm^2


Explain

Trapezium area
1/2h (a+b)

Base area = 1/2h (a+b)

Base area = 1/2(3)(8+12)


As 20/2 = 10

Base area = 3(10)

Base area = 30 cm^2

Use perimeter: 28

Base Area = 30
Height = 10


Surface area = 2(30)+28(10)

Surface area= 60+ 280

Surface are = 340


Glad this help you

Good luck :-D

Selecting an SUV with a blue exterior
frozen [14]

The answer is straightforward, by the "rule of product":

There are

3×8×2=48

3×8×2=48

different combinations (distinct possible cars) that can be created.

There 33 choices for body style; 88 choices for exterior colors, and 22 choices of interior color schemes:

Since each of these choices are independent (the choice of body style doesn't depend on exterior or interior color, e.g.) we multiply the number of choices for each quality to obtain: 3×8×2=483×8×2=48 distinct ways to create a car

What is the measure of the central angle of a circle with radius 60 cm the intercepts a 15 pi centimeters arc
alekssr [168]

The measure of the central angle of a circle is 45⁰

<h3>What is Angle?</h3>

A figure which is formed by two rays or lines that shares a common endpoint is called an angle.

Here,

Theta (angle) θ = arc length / radius

θ = 15 π / 60 cm

θ =  0.79 radians

Convert to degrees

θ = 0.79 radians = 0.79 X 180/ π

                     = 0.79 X 180/ 3.14

                     = 45⁰

Thus, the measure of the central angle of a circle is 45⁰.

Dori and Malory are tracking their steps taken as a health goal. Dori leaves her house at 12:00 p.m. and walks at 50 steps per m
docker41 [41]

Hi There!


Dori leaves her house at 12pm.

50 steps per minute until 12:20pm.

Dori has a 20 minute advantage over Malory, find the amount of steps she is ahead by,

12 - 12:20pm. steps = 20 minutes = 20 x 50 = 1000 steps


Malory leaves her house at 12:20pm.

Walks 90 steps per minute.

12:20 -  12:30 pm. = 10 minutes = 10 x 90 = 900


Dori 12:20 - 12:30pm. = 10 minutes = 10 x 50 = 500

500 + 1000 = 1500


Mallory 12:30 - 12:40 = 10 minutes = 10 x 90 = 900

900 + 900 = 1800


Dori 12:30 - 12:45pm. = 15 minutes = 15 x 50 = 500

1750 + 500 = 2250


Mallory 12:40 - 12:45pm. = 5 minutes = 10 x 90 = 900

450 + 1800 = 2250


Answer: they have the same number steps at 12:45 p.m.


Hope This Helps :)
