Answer:
Step-by-step explanation:
The marked angles form a linear pair, so have a sum of 180°.
(4a +10) +(6a) = 180
10a = 170 . . . . . . . . . . subtract 10
a = 17 . . . . . . . . . . . . . divide by 10
__
Then the measure of angle ABC is ...
∠ABC = 4a +10 = 4(17) +10 = 68 +10 . . . . . substitute 17 for 'a'
∠ABC = 78°
The air plane is rising so the change in elevation is +1000 feet. The temp dropped and is -20 degrees fahrenheit.
1 degree per 50 ft
For every 1,000 feet that it climbs, the outside temperature drops 20 ... What is the rate of temperature change in degrees Fahrenheit per foot.
Answer:
80cm^3
Step-by-step explanation:
To find the volume of the figure, we can see the shape comprises of both cube and cuboid
Volume of cuboid = length x breadth x height = 6x4x3= 72cm^3
Volume of cube = length xlength x length = 2×2×2 = 8cm^3
The volume of the figure = volume if cuboid and cube = 72+8 = 80cm^3

Answer:
The equation of the line with a y-intercept of 4 and a point (8,8) is 
Step-by-step explanation:
A linear equation can be expressed in the form
y = m * x + b
where x and y are coordinates of a point, m is the slope and b is the y-intercept. Since this equation describes a line in terms of its slope and its y-intercept, this equation is said to be in its slope-intercept form.
Graphically this equation represents a line.
In this case, you know:
- The point (x,y)=(8,8)
- Y-intercept= 4
Replacing:
8=m*8 +4
Solving:
8-4=m*8
4=m*8
4÷8= m
Then, <u><em>the equation of the line with a y-intercept of 4 and a point (8,8) is </em></u><u><em></em></u>
