For equations like this u definitely need a graphing calculator, if u dont have one, u can download the all called wabbit and plug in the numbers, but rn ill do it for u. so its either A. or B. which i would go for A.
Answer:
1 = 130° , 2 =50° , 3 = 85°, 4=45°
Step-by-step explanation:
1 =45 + 85 = 130 { sum of opposite interior angle equals exterior angle}
2 = 180 - 1 { angles on a straight line equals 180}
= 180 -130 = 50°
4 = 180 - 135 = 45° { angles on a straight line equals 180}
3 = 135 -2 { sum of opposite interior angles equals exterior angle; 3 + 2 = 135}
3 = 135-50 = 85°
Note : sum of opposite interior angles equals external exterior angle, let's prove it:
If we look at the triangle at the bottom left, we have :
85, 45 and r { let's denote r as the missing angle}
So 85 + 45 + r = 180° { sum of angles of a triangle}
By simple arithmetic
r = 180 - ( 85+45) = 180 - 130 = 50°
but r + 4 = 180° { sum of angles in a straight line equals 180°}
4 = 180 - 50 = 130°
So you see 4 is the exterior angle of the triangle opposite to 85° and 45° interior angles}
Answer:
X ≥ 10,000
Step-by-step explanation:
The ‘x’ represents the money they raised and the inequality would be ≥ because you would want to raise at least $10,000 or more.
Answer:
Step-by-step explanation:
340/25 = 13.6 = 13 hours and 10 min
30 x 13.6 = 408 hours
25x+30y= 340 and y=2x can be used to determine the number of hours cooper worked and the number of hours isaiah worked. Where x Isaiah 's working hours and y is cooper's working hours.
Step-by-step explanation:
Isaiah ironing rate per hour = 25 shirts
Cooper ironing rate per hour = 30 shirts
Total shirts pressed = 340
Let,
Isaiah´s number of hours = x
Cooper's number of hours = y
According to given statement;
25x+30y=340 Eqn 1
Hudson worked twice many hours as grace.
y = 2x Eqn 2

Take any number but 0 and raise it to the 0th power, and you'll get 1.
So in terms of an equation, I mean x^0 = 1 is true for any x value as long as x is nonzero.
So this means 2^0 = 1 if we replace x with 2.
