The given values lie on a line with slope
... m = (975 -725)/(30 -20) = 250/10 = 25
The initial value shown gives the y-intercept, so the length can be calculated using the equation
... y = 25x +225
_____
The length after 86 days will be
... y = 25·86 +225 = 2375 . . . feet
Answer:
m∠A = 90°
Step-by-step explanation:
In isosceles triangle base angles are congruent. That means we can equate measurments of angle B and angle C and solve for x!
m∠B = m∠C
11x - 10 = 7x + 10
4x - 10 = 10
4x = 20
x = 5
Now let's insert x back in the expressions for angles.
m∠B = (11x − 10)° = (11(5) − 10)° = 45°
m∠C = (7x + 10)° = (7(5) + 10)° = 45°
<u>Sum of all angles in the triangle is 180°.</u> Let's make an equation.
m∠A + m∠B + m∠C = 180°
m∠A + 45°+ 45° = 180°
m∠A = 90°
Assume that the tiles can be cut
remember that teh formula for a trapezoid is (base1+base2) times (1/2 height)
height=24
base1=48
base2=60
subsitute
(48+60) times (1/2 24)
108 times 12=1296
now wee find out how many tiles
16 is 1 tile
find how many 16's in 1296
1296/16=81
ans: 81 tiles
1 ) f ( x ) = 3 x
He can write { 9, 12, 18, 21, 27 } comic strips.
2 ) f ( x ) = 5 x - 3
- 13 = 5 x - 3
5 x = - 10
x = -2, etc.
The domain is: { - 2 , - 1 , 0, 3, 4 }
3 ) f ( x ) = 2 x
It will take { 8, 20, 28, 32, 36 } hours.
You add them because the key word is mix aka add 27 my dude
