(it says 8.5 at the left edge of orange) Find the total area of the prisms

Mathematics

Answer:

273.295 m^3

Step-by-step explanation:

Well I'm going to assume your talking about the volume first. :> So, let's find the orange one first cuz yes.

The rectangular prism has the volume of 8.5 x 5.7 x 4.3 and I think you should just use a calculator but I'll just tell you that the volume of this one is 208.335

Now we need to find the volume of the triangular prism which has side lengths of 3.5 6.4 and 5.8 . Now we must remember the strategy for finding the volume of a triangular prism is different because the formula is
V =(1/2)× b × h × l so lets plug in our values. Well, first 3.5 x 6.4 x 5.8 is 129.92 and then we multiply that by 1/2 and I'll tell you that it's 64.96

Finally, let us add the two values to find the total area. 208.335 + 64.96 is... 273.295 now remember the units it meters cubed!

Find the slope and write an equation with these to points (0,-2) (3,1)<br><br> plz explain
tatiyna

Hello There!

Slope: 1

Equation: y = x - 2

Let's start by finding the slope. To find the slope of a given equation, subtract the y values over the x values.

y1 - y2 / x1 - x2 ⇒ 3 - 0 / 1 - - 2 ⇒ 3 / 3 ⇒ 1

This means we have a slope value of 1.

Now, to find an equation. We will find the equation in slope intercept form, or y = mx + b. (In this case, m = the slope and b = the y-intercept, and x and y equal your x and y values fro a given point.)

To get the equation, we need to find the value of b, or the y intercept. To do this, we need to plug in the values we know into the equation.

we know m is the slope, and we know the slope is one so we can place that into the equation. We also know the points (0,-2) (3,1). We can place one of them into the equation for the values x and y.

1 = 1(3) + b

Now, simplify.

1 = 1(3) + b

1 = 3 + b

-2 = b

So, our y intercept is -2, we can plug that into the equation, making our final equation y = x - 2. We don't need to put y = 1x for the slope since multiplying something by 1 is doesn't change the number.

I hope this helps! I know my explanation might have been kind of confusing so if you need more help let me know in the comments !

PLEASE HELP WILL MARK BRAINLIEST THANK YOU
Alina [70]

Answer:

\huge\boxed{\sf 46}

Step-by-step explanation:

<u>Formula for area of rectangle:</u>

= length × width

<u>Area of the smaller rectangle:</u>

length = 7

width = 6

= 7 × 6

= 42

<u>Area of the larger rectangle:</u>

length = 7 + 4 = 11

width = 6 + 2 = 8

= 11 × 8

= 88

<u>Area of the shaded region:</u>

= Area of the larger rectangle - Area of the smaller rectangle

= 88 - 42

= 46

\rule[225]{225}{2}

Hope this helped!

Richard and Georgia both wrote essays.
LenaWriter [7]

Answer: a) Georgia, b) 120 words

Step-by-step explanation:

We can calculate how many words they each wrote by multiplying their time and the rate at which they write words.

Richard: 45*16 = 720 words total

Georgia: 70*12 = 840 words total.

Therefore, Georgia wrote 120 more words.
