For the first one it’s 1hour and 15 minutes, for the second one it’s x=3(2 1/4), x= 6 3/4, then 10- 6 3/4 = 3 1/4 not sure if that’s how you learned it but
Answer:
54 i think not sure
Step-by-step explanation:
I do not understand the second half of the question but 2671 in base 3 is 10122221
Answer:
see the explanation
Step-by-step explanation:
we know that
In a Rhombus opposite angles are congruent and consecutive angles are supplementary
The diagonals are perpendicular and bisect the angles
so
step 1
Find the measure of angle 4
we know that
--->by the diagonals bisect the angles
step 2
Find the measure of angle 1
we know that
----> by opposite angles are congruent
step 3
Find the measure of angle 2
we know that
----> by the diagonals bisect the angles
so
![m\angle 2=27^o](https://tex.z-dn.net/?f=m%5Cangle%202%3D27%5Eo)
step 4
Find the measure of angle 3
we know that
----> by the diagonals are perpendicular
step 5
Find the measure of angle 5
we know that
----> by complementary angles
![m\angle 5=90^o-27^o=63^o](https://tex.z-dn.net/?f=m%5Cangle%205%3D90%5Eo-27%5Eo%3D63%5Eo)
step 6
Find the measure of angle 6
we know that
----> by the diagonals bisect the angles
![m\angle 6=63^o](https://tex.z-dn.net/?f=m%5Cangle%206%3D63%5Eo)
Answer:
y = 2/7 x - 51/7
Step-by-step explanation:
Equation of the line
(y-y1)/(y2-y1) = (x-x1)/(x2-x1)
(y-(-7)/(-9-(-7) = (x-1)/(-6-1)
(y+7)/-2 = (x-1)/-7
(-y-7)/2 = (-x+1)/7
-y-7 = -2/7 x + 2/7
-y = -2/7x +2/7 + 7
y = 2/7 x - 2/7 - 7
y = 2/7 x + (-2-49)/7
y = 2/7 x - 51/7
