Answer:
m∠Y = 40°
Step-by-step explanation:
The sum of complementary angles is 90°. If we let s and y represent m∠S and m∠Y, respectively, the angle measures in degrees satisfy ...
s + y = 90
(4y -110) +y = 90 . . . . . . . . substitute for s
5y = 200 . . . . . . . . . add 110
y = 40 . . . . . . . divide by 5
The measure of angle Y is 40°.
Answer:
volume is 3 1/2 units³
Step-by-step explanation:
The question asks for <em>area</em>, but the answers have dimensions of <em>volume</em>.
__
The volume is the product of the length, height, and width dimensions:
V = LWH = (2)(1)(1 3/4) = 2 6/4 = 3 1/2 . . . . units³
The volume is 3 1/2 cubic units.
Answer:
a=−3
Step-by-step explanation:
Let's solve your equation step-by-step.
3(4a+4)=3a+8a+1+8
Step 1: Simplify both sides of the equation.
3(4a+4)=3a+8a+1+8
(3)(4a)+(3)(4)=3a+8a+1+8(Distribute)
12a+12=3a+8a+1+8
12a+12=(3a+8a)+(1+8)(Combine Like Terms)
12a+12=11a+9
12a+12=11a+9
Step 2: Subtract 11a from both sides.
12a+12−11a=11a+9−11a
a+12=9
Step 3: Subtract 12 from both sides.
a+12−12=9−12
a=−3
Answer:
a=−3
Answer:
A. 
Step-by-step explanation:
We have been given a table that represents the altitude of an airplane with passing minutes.
Since we know that equation of a line in slope-intercept form is: 
, where, m = Slope of the line and b = y-intercept.
To find the equation of line we will have to the slope of our given line using values from table.
, where,
= Change in two y-coordinates.
= Change in the corresponding x-coordinates.
Upon substituting the coordinates of point (1, 35000) and (2, 31000) we will get our slope as:
Now let us find y-intercept of our given line by substituting m=-4000 and the coordinates of point (1, 35000) in slope intercept form of equation.
Upon substituting the value of slope and y-intercept the equation of line will be:
Therefore, the equation representing the change in altitude a after m minutes is and option A is the correct choice.
