What is the solution for 6.50*21+f=201.50

Natasha2012 [34]

Answer:

f = 65

Step-by-step explanation:

6.50*21+f=201.50

We need to isolate f

1. multiply 6.50 by 21. 6.50 * 21 = 136.5

136.5+f= 201.50

2. Since 136.5 is positive and not being subtracted we will...

Subtract 136.5 from both sides

136.5-136.5=0+f

201.50-136.50 = 65

thus leaving f = 65

The diameter of a circle is 10 millimeters. The circumference of the circle is 62.8 millimeters.

Vilka [71]

Well, to find a circles circumference, C=D* pi. if d =10, 10 * pi (or 3.14 for now), C= 31.4. so the answer is false. It is measuring distance as a radius instead of diameter.

balu736 [363]

Answer: 629 ft

Step-by-step explanation:

$\sin 11^{\circ}=\frac{120}{x} \\ \\ x(\sin 11^{\circ})=120 \\ \\ x=\frac{120}{\sin 11^{\circ}}\approx \boxed{629}$

Melinda paints 7/8 of a wall in 1 1/6 hours. What part of a wall does Melinda paint in 1 minute

Ivanshal [37]

1 1/6 hrs.....1 hr = 60 minutes......1/6 hr = 1/6(60) = 60/6 = 10 minutes....therefore, 1 1/6 hrs = 70 minutes

(7/8) / 70 = x / 1....7/8 of the wall to 70 minutes = x wall in 1 minute
cross multiply
(70)(x) = (7/8)(1)
70x = 7/8
x = (7/8) / 70
x = 7/8 * 1/70
x = 7 / 560 reduces to 1/80 <== she paints 1/80 of the wall in 1 minute
