a triangular flower bed needs a thin metal border all the way around it. The sides are 7 feet, 6 feet, and 9 feet long.

Excuse my awful triangle drawing skills, haha..
So essentially you need to find the perimeter which is done by adding the lengths of the sides.. this gives you 22ft.
Then for part b you need to convert 22ft to yards which gives you 7.3 yards.
Since you can only buy a whole number of yards, you'll actually need 8 yards.
So if the boarder is $8.75 per yard, and you need 8 yards, how much would it cost?
Hope this was helpful.

Write the exponential function.
sertanlavr [38]

Answer:

f(x) = 10*(b)^x

Step-by-step explanation:

exponential function : y=a*(b)^x

where a = y intercept and b = factor ( what you multiply by )

looking at the table the y intercept is at (0,10) so a = 10

so we now have y = 10 * (b)^x

to find the factor we simply plug in one of the ordered pairs.

note that the ordered pair chosen does not effect the outcome

i chose (2,250)

we have y = 10 * (b)^x

(x,y) = (2,250)

250 = 10 * (b)^2

divide both sides by 10

25 = b^2

take the square root of both sides

5 = b

the final equation would be f(x) = 10 * (b)^x

What is angle DCE?<br><br> A. 34<br> B. 85<br> C. 102<br> D. 98
s2008m [1.1K]
The red line is 180 degrees. So the arcs on top of the circle all equal up to 180 degrees. the number 72 doesn't really matter cause you're trying to find out the angle of DCE which is on the other side of the circle. So you gotta find the arc length of DE which is 68 because 180-112=68. So to find the angle, you have to divide the opposite arc length by two, which is 34. 

ANSWER: A. 34. you're welcomee!!

There are 4 red marbles, 5 green marbles, 6 yellow marbles and 3 blue marbles in a bag. You select one marble at random. What is
steposvetlana [31]

Answer:

The probability can be written as;

6/18

0.333

33.3%

Step-by-step explanation:

First we find the total number of marbles.

4 + 5 + 6 + 3 = 18

Now write the probability in the form of (favourable outcomes / possible outcomes), or 6/18.

Now let's divide.

6 ÷ 18 = 0.33333333... repeating decimal

0.333 × 100 = 33.33333.....%

We can also round this to 33%

I JUST NEED 4 PLS!!!!!!
Alchen [17]

Answer:

C

Step-by-step explanation:

When doing 4 divided by 2 you get 2. Looking at the sign it is saying 3 is greater than the number we solve for. Since we solved and got 2 we can double check and ask is 3 greater than 2? Yes it is so that would make the statement correct.

Hope this Helps :)
