Answer:
∠ PTQ = 70°
Step-by-step explanation:
The angles subtended by the radii and tangents to the circle , sum to 180°
∠ PTQ + 110° = 180° ( subtract 110° from both sides )
∠ PTQ = 70°
Answer:
y=3/4m
Step-by-step explanation:
All proportional relationships have the form y=mx where m is the rate of change from the families donations x to the business donations y. We can find the rate of change m by substituting values we already know. We know when x=$12 then y=$9.
9=m*12
We solve for m by dividing by 12 on both sides.
m=9/12
This simplifies to 3/4 so
m=9/12=3/4.
The equation is y=3/4m
Step-by-step explanation:
y |X(the sign for protionality) 1/√x
y = 7 when x = 36
y = k/√x
7 = k/√36
7 = k / 6 cross multiply
k = 7×6
k = 42
find y when x is 4
y = 42/√x
y = 42/√4
y = 42/2
y = 21
I dont know if i did this right but here
x1 = 9.5 y1 = 0
These are similar triangles so proportions hold. the short side to the bottom side proportion must be the same in both triangles. to solve it
25/30 = 35/x. (25+10=35 is the side of the bigger triangle
cross multiply and solve for x
25x=1050
x=1050/25=42
