What is the answer to this in cm
jasenka [17]
The hardest part is finding the length of the curve at the top. To find arc length, multiply the circumference by the arc angle divided by full angle (360°) in a circle. Or:
s = (2\pi  r)( \frac{x}{360})
x, the arc angle in a semicircle, is 180°.
r, the radius is 7/2 = 3.5.
Now just plug the numbers in and solve for arc length, s.

s = 2π(3.5)(1/2) ≈ 11.00

Now just add up all the sides. 11cm + 10cm + 10cm + 7cm = 38 cm.

5. Find the total cost to the nearest hundredth. $12.99 T-shirt, 6% tax
Vlada [557]

Answer:

$13.80

If p is the midpoint of line xy, xp=11-6b and py=6-b, find xp
MariettaO [177]
Since p is the midpoint then xp and pay must equal each other
So, 11-6b=6-b
Solve for b
11-6b=6-b
-6 -6
5-6b=-b
+6b +6b
5=5b
b=1

xp=11-6(1)
xp=5

3/5 of gallon of juice is poured equally into 6 glasses . How much juice is in each glass?
Setler [38]
Hi there! For this question, we will have to divide. When it comes to dividing fractions, we keep, change, flip. In other words, keep the first fraction the same, change division into multiplication, and flip the second fraction over by its reciprocal. In this case, 3/5 stays the same and 6/1 becomes 1/6. 3/5 * 1/6 is 3/10 or 1/10 in simplest form. There. There are 1/10 gallon of juice in each glass.

A plumber charges 130 to start job plus 56 per hour . How many hours did she work if the total bill is 214
iragen [17]

Answer:

The plumber worked for 1.5 hours

Step-by-step explanation:

y = 130 + 56x

Substitute 214 for y in the equation

214 = 130 + 56x

-130   -130                      Subtract 130 from both sides

84 = 56x                         Divide both sides by 56

1.5 = x
