She spent 5.4 on tip so her overall total is $41.40
2*4=8
8/5=1.6
1.6miles:12minutes
60/12=5
5*1.6=8
Blake's avg. speed is 8mph
Answer:
B
Step-by-step explanation:
Hey There!
they are asking for the equation in slope intercept form
Slope intercept form is y=mx+b
where m equals slope and b equals y intercept
to find the slope we do change in y over chang in x
as y goes up 2 x goes down 5 so the slope would be -2/5
the y intercept is at (0,4) so the y intercept is 4
now we add everything together and get that the equation in slope intercept form is
y=-2/5x+4
so we can conclude that the answer is B
Answer:
Therefore,
The surface area is
Step-by-step explanation:
Shape is triangular prism,
Base = b = 9
Height = h = 7
The length of each side of the triangular prism ,
s₁ = s₂ = s₃ = 9
Width of the entire prism
Width = W = 7
To Find:
The surface area = ?
Solution:
Total Surface Area of Prism is given by,
Where,
b = Base
h = Height
s₁ , s₂ , and s₃ = length of each side of the triangular prism
W = width of the prism
Substituting the values we get
Therefore,
The surface area is
Answer:
The volume of cyclinder is 60 in³
Step-by-step explanation:
Using the formula of the volume of cyclinder, V = π×r²×h, where r is the radius and h is the height. Then you are able to find it by substituing the following value into the formula :
π = 3.14
r = 1.8 in
h = 5.9 in
V = 3.14×1.8²×5.9
= 60.0 in³ (3s.f)
