Answer:
150°
Step-by-step explanation:
The sum of the angles in a quadrilateral = 360°
Divide by the sum of the parts of the ratios to find the value of one part of the ratio.
sum of parts , 3 + 2 + 2 + 5 = 12 parts
360° ÷ 12 = 30° ← value of 1 part of the ratio , then
3 parts = 3 × 30° = 90°
2 parts = 2 × 30° = 60°
5 parts = 5 × 30° = 150°
The largest angle in the quadrilateral is 150°
F(x)=X-11
F(-3)= -3-11
F(-3)=-14
F(x)=X-11
F(-2)=-2-11
f(-2)=-13
F(x)=X-11
F(4)= 4-11
f(4)=-7
F(x)=-7x+1
F(-3)=-7(-3)+1
F(-3)=-21+1
F(-3)=22,
F(x)=-7x+1
F(-2)=-7(-2)+1
F(-2)= 14+1
f(-2)=15,
F(x)=-7x+1
F(4)=-7(4)+1
f(4)=-28+1 =-27
F(x)=X+8
F(-3)=5, f(-2)= 6 , f(4)=12
(3/7) and (7/15) are oak.
(2/3)(7/15)(3/7)T are new oaks
(1/3)(7/15)(3/7)T are old oaks
------
(1/3)(7/15)(3/7)T = 160
(1/15)T = 160
I believe 160 x 15 - 2,400.
My best guess is there are 2,400 trees in the forest.
Answer:
12 years old
Step-by-step explanation:
7 + 5 = 12
T + 5
There are 40 students in the class.
15 % + 25 % = 40%
So 24 must be equal to the remaining 60% and 24 is 60% of 40.
Hope it helps!
