There’s this app called Photomath and it helps with math:) have a great day
Answer:
x= 43.89
Step-by-step explanation:
Start off with your ratio. Because we're finding an angle, we'll use -1.
Since it's the opposite and adjacent, TAN is the ratio we're using here.
(tan is opposite/adjacent)
Tan -1x = 101/105
in your calculator, divide 101 and 101
=0.9619
then with this number, hit 2nd and Tan and enter and you will get
x= 43.89.
Area of figure is the total number of 1 square unit in the figure. For a rectangle, it is calculated from the product of its length and its width. For this case, we are given:
Width = x
Length = 7x
Area = x(7x) = 7x^2
The coefficient 7 would mean that the length is 7 times longer than the width, x.
Answer:
Get a calculator
Step-by-step explanation:
Most of the time for simple math like multiplying 2 digits, it is easiest if you just get a calculator. It saves a lot of time.
If you can't get a calculator then i recommend memorizing some common equations.
For example 10*15= 150
so that if you get 12*15=?, you can easily just add two extra 15's to your answer of 150.
15+15 is 30, and 30+150(from 10*15)=180.
Therefore 12*15=180.

Y = -9x - 10
The dolphin is diving 9 feet per second so the rate of change is -9.
It's also 10 feet below sea level which makes the y-intercept -10
Hope this helped!
