Answer:
combination
Step-by-step explanation:
We have that permutations are groupings in which the order of the objects matters. Combinations are groupings where content matters but order does not.
In this case we have a list of ingredients for the pizza, therefore the order does not matter as long as the ingredients are indicated, which means that this is an example of a combination.
Answer:
It is 6. The student who got a two did not use order of operations.
Step-by-step explanation:
PEMDAS
You must do division before subtraction. 4/2 = 2.
8 - 2 = 6
Let
x,y, and z the long sides of the triangle
we know that
x+y+z=170 ft------> equation 1
x/y=25/14----> y=14x/25------> equation 2
y/z=14/12-----> equation 3
x/z=25/12----> z=12x/25------> equation 4
substitute equation 2 and equation 4 in equation 1
x+[14x/25]+[12x/25]=170------> multiply by 25 both sides
25x+14x+12x=4250
51x=4250
x=4250/51
x=250/3
y=14x/25------> y=(250/3)*(14/25)----> y=140/3
z=12y/14-----> (140/3)*12/14----> z=40
Using Heron's formula,
Area of the triangle = √s (s-a) (s-b) (s-c)
where s is the semiperimeter
s=170/2-----> s=85 ft
Area=√85*[85-250/3]*[85-140/3]*[85-40]
Area=9.22*[1.67]*[38.33]*[45]------> Area=26558.21 ft²
the answer is
26558.21 ft²
<span>Melinda and Paul shovel driveways and sidewalks in the winter as a way to earn extra money. </span>Melinda can shovel in 1 minute and Paul can shovel in 9 square feet per minute.
First calculate the sum or difference: 8+(8+9)-19 x 5.
Second calculate the product or quotient: 8+17-19 x 5
Third calculate the sum: 8+17-95
Lastly subtract 25 - 95.
Then your answer is -70. Please give brainliest!
