How many faces have an area of 6 cm2?

How Many Faces Have An Area Of 6 Cm2?

Answers

Answer 1

Answer:

2

Step-by-step explanation:

There are 6 sides:

3 by 4 = 3*4 = 12, no

3 by 3  = 3*3 = 9, no

5 by 3 = 5*3 = 15, no

Triangles:

Half of 3 by 4 = 1/2 * 3* 4 = 1/2 * 12 = 6, yes

The other triangle is the same, so 2

Answer 2

Answer:

two

Step-by-step explanation:

Area of the rectangle on the left = 4 * 3 = 12 cm^2

area of the square = 3^2 = 9 cm^2

Area of the rectangle on the right = 5 * 3 = 15 cm^2

Area of the two triangles = (4 * 3)/2 = 6 cm^2

The quadratic function h(t) = −4.9t^2 + 50t + 2 represents the height, in meters, of a toy rocket t seconds after launch. How many seconds will it take the toy to reach the ground? State your answer to the nearest whole second.

Answers

Answer:

The toy reaches the ground in 10 sec

Step-by-step explanation:

When the rocket hits the ground, h becomes zero (0).  Thus, our problem here is to solve the equation h(t) = −4.9t^2 + 50t + 2 = 0,

Because of the fractional coefficient -4.9, it's best to use the quadratic equation here.  The coefficients of the t terms are {-4.9, 50, 2}.  Thus,

the discriminant is b^2 - 4ac  = 50² - 4(-4.9)(2) = 2539.2, and the square root of this is 50.39.

The quadratic formula is as follows:

      -b ± √discriminant

t = -------------------------------

                 2a

which here is:

      -50 ± 50.39

t = ------------------------      Since t represents time, only the positive result

               -9.8                 is relevant here; it is 10.24 sec,

which rounds off to 10 sec

The toy reaches the ground in 10 sec

it reaches the ground in 10 sec

Answers

Answer:

1) x= -1/27

2) x=-4

3) x=13

Step-by-step explanation:

1) 7+7/9x= = -42

   14/9x= = -42

  14/9x X 9x= -42 X 9x

    14= -378x

    -378x= 14

   -378x/-378= 14/-378

      x= -1/27

2) 4x+1=−15

 4x+1-1=-15-1

    4x=-16

   4x/4= -16/4

      x=-4

3) −4(x−3)=−40

 -4(x-3)/-4= -40/4

Find the Area of the shape
(Area of Composite Shapes)

Answers

Answer:

223.5 Km

Step-by-step explanation:

Area = Length x Width

Solving for Square Shape

8 · 6 = 48 km

Area = Length x Width

Solving for Rectangle Shape

9 · 14 = 126 km

Area = Length x Width ÷ 2

Solving for Triangle Shape

11 · 9 = 99 ÷ 2 = 49.5 Km

48 + 126 + 49.5 = 223.5 Km

V represents the vacation hours and H is the hours worked

If they both work 2080 hours

V1 = (0.04)*(2080) = 83.2 vacation hours (Company P)

V2 = (0.06)*(2080) = 124.8 vacation hours (Company S)

the image below, what is true about angles 1, 2, and 3?

A. 3 = 37
B. 1 = 37
C. 2 = 37

Answers

Answer:

C. 2 = 37

Step-by-step explanation:

<2 and 37 are vertical angles and vertical angles are equal

Angle 1 and 37 form a straight line so they add to 180

<1 + 37 = 180

<1 = 180-37 = 143

Angle 3 and 37 form a straight line so they add to 180

<3 + 37 = 180

<3= 180-37 = 143

answer is C 2= 37 because the angle properties says that if it is an opposite angle it has the same angles..

Answers

Answer:

it depends on the work place to play it safe i would choose 12

Step-by-step explanation:

The sample mean is equal to 24 and population mean is equal to 25

What is sample mean?

Sample mean represents the measure of the center of the data. The sample mean formula is used to calculate the average value of the given sample data.

Sample mean= sum of the terms/number of the terms

What is population?

The population in static is used for a collection of data. The population mean can be calculated by the sum of all values in the given population divided by a total number of values in the given population.

Population mean= sum of the population/ number of the population

From the given question average of entire year is 25.

According to the population mean formula the sum of the population by number of the population is nothing but the average of the entire year. Thus the population mean is 25.

According to the sample mean formula,

sample mean= sum of the terms / number of the terms

⇒(25+10+16+39+27+25+32+25+25+22+28+14)/12 = 24

Thus the sample mean is equal to 24 and population mean is equal to 25

As surface water in a lake cools from 4 C to 0 C, the water expands and becomes less dense. Why is this change in the water beneficial to the organisms living in the lake? As the water cools to freezing, spaces form between water molecules, providing microhabitats for small organisms. Frozen surface water insulates the water below it, maintaining a habitat where organisms can overwinter. Cooler water is less viscous than warmer water, making it easier for organisms to move through the water. Less dense water holds more dissolved compounds, keeping water from freezing so organisms survive winter.
