Help!!!
Answer:
84 cm^2
Step-by-step explanation:
Area of triangle + area of rectangle
Area of triangle = 1/2*l*b
= 1/2*8*3= 12 cm^2
Area of rectangle = l*b
= 12*6 = 72 cm^2
Total area= 72+12
= 84 cm^2

The approximate total surface area of Earth is 5.1 × 10^8 km2. All the salt water on Earth has an approximate surface area of 352,000,000 km2, and all the freshwater on Earth has an approximate surface area of 9 × 10^6 km2. How much of Earth's surface is covered by water, including both salt and fresh water? Write your answer in scientific notation.Single line text.
Answer:
3.61x10^8km^2Step-by-step explanation:
In this problem, we are expected to solve for the total area covered by water, by addition of scientific notation
Given data
Area covered by salt water= 352,000,000 km2
Area covered by fresh water= 9 × 10^6 km2=9,000,000
Earth's surface is covered by water= 352,000,000 +9,000,000
Earth's surface is covered by water= 361000000
In scientific notation it is 3.61x10^8km^2

d + 3n = 1 can someone help?
Answer: n = (1 - d) / 3
Step-by-step explanation: We are given with the equation d + 3n = 1 and asked to solve for n in the problem. the first step is to apply subtraction property by subtracting d to each side of the equation. Hence 3 n = 1 - d. next, we use division property by dividing the whole equation by 3.

What is the value of g(3) ?
Answer:3
Step-by-step explanation:
A function from a set X to a set Y assigns to each element of X exactly one element of Y. The value of g(3) is 3
What is a function?A function from a set X to a set Y assigns to each element of X exactly one element of Y.
We need to find the value of g(3).
From the question, we have
g(x)= x-1, -2≤x<-1
g(x)= 2x+3, -1≤x<3
g(x)= 6-x, x≥3
The value 3 is in the function g(x)=6-x
When x is 3
g(3)=6-3
Subtract 3 from 6.
g(3)=3
Therefore value of function g(3) is 3.

someone helpp, I don’t know how to solve it nor do I know the answer.
========================================================
Explanation:
For any parallelogram, the diagonals cut each other in half. Formally this is known as bisection.
What this means is that the pieces AE and CE are the same length.
AE = CE
6x-8 = 2x+24
6x-2x = 24+8
4x = 32
x = 32/4
x = 8
Then we can calculate the length of each piece mention
AE = 6x-8 = 6*8-8 = 48-8 = 40CE = 2x+24 = 2*8+24 = 16+24 = 40Both pieces are 40 units long to confirm we have the correct x value.
Therefore,
AC = AE + CE = 40+40 = 80

rows=x=11Suppose y varies directly with x. Write a direct variation equation that relates x and y.
y=-10 when x=2
Answer: Suppose y varies directly with x. Write a direct variation equation that relates x and y.
Step-by-step explanation:
Answer is y = -5x
The equation for y varies directly with x is, y = - 5x.
What are ratio and proportion?A ratio is a comparison between two similar quantities in simplest form.
Proportions are of two types one is the direct proportion in which if one quantity is increased by a constant k the other quantity will also be increased by the same constant k and vice versa.
In the case of inverse proportion if one quantity is increased by a constant k the quantity will decrease by the same constant k and vice versa.
Given, y varies directly with x.
Therefore,
y ∝ x.
y = kx, where k is the proportionality constant.
At y = - 10 when x = 2.
- 10 = 2k.
k = - 5.
So, y = - 5x.
