Answer:
m/_A=112°, m/_B=68°, m/_C=112°
Step-by-step explanation:
m/_A is 112° since consecutive /_s in a parallelogram are supplementary therefore 180°(<- supplementary sum)-68°(<- m/_D)=112°(<- m/_A, and m/_C), and in a parallelogram, one main property is opposite /_s are congruent therefore m/_B is congruent to m/_D so m/_B=68°.

Answer:
0.7 is the decimal expansion okok
Step-by-step explanation:
To calculate this you’ll have to subtract and then divide
1500= 500+50t
1.) subtract 500 from 1500 to break down the equation
1500-500 =500+50t -500
1000= 50t
2.) now you want to get t alone... so since t is multiplied by 50, you will do the opposite and divide 50 from 1000 in order to get rid of it- which will again break down the equation
1000 /50= 50t /50
20= t
The answer is 20 minutes

Answer:
The diameter of the floor is 6 yards
Step-by-step explanation:
Here, we are to calculate the diameter of a circular floor that has a circumference of 18.84 yards
Mathematically,
C = π * D
where C is the circumference
Plugging the values of the circumference , we have ;
18.84 = 22/7 * D
7 * 18.84 = 22D
D = (7* 18.84)/22 = 5.99 which is approximately 6 yards
1.5= 1 lap+ 0.5 lap = [2(85)+pi*(d)] + [85+pi*d/2]= 3[(85)+pi*d(1/2)]
just substitute d=74
