Answer:

Triangular prism 1:    132

Triangular prism 2:   828

Step-by-step explanation:

1) triangle+triangle+rectangle+rectangle+rectangle

A of triangle=3*4 divided by 2

12/2= 6

since there are 2 triangles we do 6*2= 12

A of rectangle 1= 10*5= 50

A of rectangle 2= 10*4= 40

A of rectangle 3= 10*3= 30

so SA of whole figure is 12+50+40+30= 132

2) triangle+triangle+rectangle+rectangle+rectangle

A of triangle=9*12 divided by 2

108/2=54

since there are 2 triangles we do 54*2=108

A of rectangle 1= 9*20=180

A of rectangle 2= 15*20=300

A of rectangle 3= 12*20= 240

so SA of whole figure is 108+180+300+240=828

Answer:

multiplication

same thing as 2.5 * y

Step-by-step explanation:

Okay, so first off, if you need to graph anything, I suggest Desmos, it's a website with an online graphing calculator. It saved my life for highschool geometry.

Now, to answer your question, your y-intercept is going to be at point (0,2). Your x-intercepts are going to be at points (-2,0) and (-4,0). Your point is at (-3,-1). And then your lines simply extend from there.

Hope this isn't too late to be helpful, good luck with your assignments.

Answer:

Here’s the answer Volume of a sphere with diameter 6 cm =?

Step-by-step explanation:

Diameter of sphere => 6 cm therefor, Radius =3 cm volum of the spher = 4/3 and the pie sign r to the 3 power = 4/3 x 3.14 x 3 with the power of 3 = 4/3 x 3.14 x x 3x3 x 3 = 4 x 3.14 x 3.14 x 3 x 3 = 113.04cm cubed Thus, volume of the sphere = 113.04 cu. cm

Step-by-step explanation:

and also you are diviing the numbers then subtracting 9

Answer:

-3 ∛3 - 4 ∛6 + 4 ∛3

Step-by-step explanation:

∛81 = ∛3x27 = 3 ∛3

2 ∛48 = 2 ∛6x8 = 2x2 ∛6 = 4 ∛6

2 ∛24 = 2 ∛8x3 = 2x2 ∛3 = 4 ∛3

-3 ∛3 - 4 ∛6 + 4 ∛3

plug 88 into h and solve for t

Answer:

∠ABC= 40°  ∠CBD=60°  ∠EBD=80°

Step-by-step explanation:

Step 1: 2x+3x+4x=180

          A straight line is 180 degree's, and to get the value of the different angles, you have to add the three angle measures.

Step 2: 9x=180

            Combine like terms

Step 3: x=20

            Divide/ Isolate the variable

Step 4: 2(20)=40   3(20)=60    4(20)=80

           Plug the answer back in

Answer:

-138

Step-by-step explanation:

Distance between midpoint and point (-100) = -100 - (-119)

                                                      = 19

Since the [distance between the midpoint and point (-100)] and the [distance between the midpoint and point A] is the same, the distance between the midpoint and point A is also 19. You already know the midpoint is at -119. Since the midpoint is lower than point (-100), point A should be lower than point (-100).

Point A = -119 - 19

Point A = -138

[tex]\frac{1}{3}[/tex]×[tex]\frac{1}{4}[/tex]=[tex]\frac{1}{12}[/tex][tex]ft^2[/tex]

Answer:

y = -8x

Step-by-step explanation:

First let's look at what slope-intercept form is.

y = mx + b

m is the slope, which in this case is -8.

b is the y-intercept, which we will find later.

Now that we have identified the parts of the equation, let's plug in what we know. Use the point given for your x and y values.

y = mx + b

16 = -8(-2) + b

Let's simplify this to find b.

[multiply] 16 = 16 + b

[subtract 16] 0 = b

We now have our b-value, which is also our y-intercept. Plug in this value into the standard slope-intercept equation.

y = -8x

This is your equation.

Check this by plugging in the point again.

16 = -8(-2)

[multiply] 16 = 16

This expression is true; therefore, your answer is correct.

Hope this helps!

Answer:

Hi i'd love to help! but what is this comprehension about?

Answer:

The third one.

Step-by-step explanation:

On a number line, the circle would be on 5 with an open circle (because 5 is not included in the inequality) and the arrow would go to the right. The right arrow includes all values greater than 5.

Hope this helps.

Answer:

it is the one you picked

Step-by-step explanation:

When it is a greater or less than sign, it will be a opened circle whereas when it is a closed circle, it is a greater than/ less than or equal to.

I hope this helps!

Answer:

Algebraic Expression

Answer:

The spinner would land three times

Step-by-step explanation:

This is because 3, 15, and 9 are multiples of three

Answer:

B

Step-by-step explanation:

2a+45=180

subtract 45 from both sides which equals 2a=135

divide both sides by 2 which would solve for a.

Answer: 7
