For 40points. Find the volume?

joja [24]

Hey!

------------------------------------------------

We can split this polygon into two rectangular prisms.

Finding the volume is: base * length * height.

~Let's solve for the first prism

5 * 2 * 2 = 20cm³.

~Let's solve for the second prism

8 * 2 * 2 = 32cm³.

~Add both volumes

32 + 20 = 52cm³.

------------------------------------------------

Hence, the volume is 52cm³.

Complete the steps to find the value of x

Anastasy [175]

Answer:

x=7

Step-by-step explanation:

(8x+6)=m∠4

m∠4 + 118 = 180

(8x + 6) +118 = 180

(8x + 6) + 118 - 118 = 180 - 118

8x + 6 = 62

8x = 56

x = 7

Hope this helps!!!

I’m stuck can some one help me

abruzzese [7]

Answer:

3) Midpoint is (-4,0.5)

Option A is correct.

4) Midpoint is (2.5,0)

Option B is correct.

5) The factors are (x+4)(x-7)

Option C is correct.

6) The factors are (x+4)(x+2)

Option A is correct.

Step-by-step explanation:

Question 3

Find midpoint of the following:

(2,-7), (-10,8)

The formula used to find midpoint is: $Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )$

We have $x_1=2, y_1=-7, x_2=-10,y_2=8$

Putting values and finding midpoint

$Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )\\Midpoint=(\frac{2-10}{2},\frac{-7+8}{2} )\\Midpoint=(\frac{-8}{2},\frac{1}{2} )\\Midpoint=(-4,0.5 )$

So, Midpoint is (-4,0.5)

Option A is correct.

Question 4

Find midpoint of the following:

(2,-10), (3,10)

The formula used to find midpoint is: $Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )$

We have $x_1=2, y_1=-10, x_2=3,y_2=10$

Putting values and finding midpoint

$Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2} )\\Midpoint=(\frac{2+3}{2},\frac{-10+10}{2} )\\Midpoint=(\frac{5}{2},\frac{0}{2} )\\Midpoint=(2.5,0 )$

So, Midpoint is (2.5,0)

Option B is correct.

Question 5

Factor each completely

$x^2-3x-28$

We will break the middle term and find factors

$x^2-3x-28\\=x^2-7x+4x-28\\Taking\:common\\=x(x-7)+4(x-7)\\=(x+4)(x-7)$

So, the factors are (x+4)(x-7)

Option C is correct.

Question 6

Factor each completely

$x^2+6x+8$

We will break the middle term and find factors

$x^2+6x+8\\=x^2+4x+2x+8\\=x(x+4)+2(x+4)\\=(x+4)(x+2)$

So, the factors are (x+4)(x+2)

Option A is correct.

Orla and Eduardo each looked at a strand of their hair under a microscope and measured the diameter. Orla's strand was 0.005cm i

bezimeni [28]

Answer: The diameter of Eduardo's hair is greater than Orla's hair by 0.007 cm.

Step-by-step explanation:

Given: The diameter of Orla's hair strand = 0.005 cm

The diameter of Eduardo's hair strand = 0.012 cm

Clearly , $0.012>0.005$

The difference between the diameters= $0.012-0.005=0.007\ cm$

Thus, the diameter of Eduardo's hair is greater than Orla's hair by 0.007 cm.
