Answer:

2520°

Step-by-step explanation:

The sum of the angles in any triangle is 180°

shape. sides. triangles. sum int angles.

triangle. 180×1=180°

quad. 180×2=360°

pentagon. 180×3=540°

n-sides. n( n−2) 180(n−2)

16-sides. 180×14=2520°

Jon makes a mix of salad that cost $15 using as much apples that cost $4/kg as oranges that cost $6/kg. How much of each fruit i
marysya [2.9K]
Let
 x = number of apples.
 y = number of oranges.
 we have to write the following equation to represent the problem:
 4x + 6y = 15
 To satisfy the equation, Jon must have used
 x = 2.25
 y = 1
 Substituting
 4 (2.25) +6 (1) = 15
 9 + 6 = 15
 answer
 Jhon used 2.25kg of apple and 1kg of orange to make the salad.
 Note: Since the problem does not have any other restrictions, there may be several apple and orange combinations that cost $ 15 per salad.

Stacy wants to build a patio with a small, circular pond in her backyard.The pond will have a 6-foot radius. She also wants to i
solong [7]
First we are going to find the Area of the pond using the area of a circle formula: A= \pi r^2
where
A is the area of the circle 
r is the radius of the circle 
We know for our problem that the pond will have a 6-foot radius, so r=6. Lets replace that value on our area formula:
A= \pi r^2
A= \pi (6)^2
A=113.1ft^{2}
We know that the <span>cost of installing the pond is $0.62 per square foot, so lets multiply the area we just found by the cost:
Total cost of pund=</span>(0.62)(113.1)=70.12 dollars

Now, let x be the width the rectangle, so its length will be x+13. Remember that the area of a rectangle is width times length, so:
A=x(x+13)
A=(x^2+13x)ft^2
Since the cost of installing ties is $1, the cost of installing ties in our rectangle will be x^2+13x dollars.

<span>Stacy can spend no more than $536 on this project, so we can setup an inequality relating the cost of the pound and the cost of installing ties:
</span>70.12+x^2+13x \leq 536
x^2+13x \leq 465.88

We can conclude that the inequality that can be used to fin the width, x, of the patio is x^2+13x \leq 465.88

Answer:

M1, A1, T1, H1, M5, A5, T5, H5

Step-by-step explanation:

So from each of the first branches, we would consider the sample space of choosing a letter from the word MATH. There would be 4 branched, with M, A, T, and H. From each of those, you would have to split them into 2 branches, one for the 1 and one for the 5, from the digits of 15. So you would end up with 8 total branches at the end.
