Answer:
75 degrees
Step-by-step explanation:
sum of all angles in a triangle is=180 degrees
180 degrees -70 degrees- 35 degrees=75 degrees
mark me as brainliest plz
Answer:
Outside temperature at 2 A.M = -33.2°C
Step-by-step explanation:
Given:
Temperature at 12:00 midnight (outside) = -30.9°C
Rate of decreases = - 2.3°C per two hour
Find:
Outside temperature at 2 A.M
Computation:
Outside temperature at 2 A.M = Temperature at 12:00 midnight (outside) + Rate of decreases
Outside temperature at 2 A.M = -30.9°C + (- 2.3°C)
Outside temperature at 2 A.M = -33.2°C
Plot the equation. If you wish to solve a polynomial, let y= polynomial and plot the graph. Best set up a table of values first.
Where the graph crosses the x axis there is a solution for x. There are also solutions for other horizontal lines (y values) by looking at intersections of the graph with these lines. This technique works for linear and non linear equations. You can also use graphs to solve 2-variable systems of equations by examining where the graphs intersect one another. The disadvantage is that you may not be able to have sufficient detail for high degrees of accuracy because of the scale of the graph and drawing inaccuracies.
The dimensions that would result to maximum area will be found as follows:
let the length be x, the width will be 32-x
thus the area will be given by:
P(x)=x(32-x)=32x-x²
At maximum area:
dP'(x)=0
from the expression:
P'(x)=32-2x=0
solving for x
32=2x
x=16 inches
thus the dimensions that will result in maximum are is length=16 inches and width=16 inches
B)7:8 is the answer because:
16 total - 7 green = 8 and so
the ratio of GREEN to RED is
7:8
7 green 8 red
For a) it would be 1:2 as it is 16:8 and simplified would make it 1:2
