Sweet onions are on sale for $0.79 per pound. If an onion weighs 8 oz, how much does it cost to buy 5 onions?
Answer:
a pound is 16 oz. so 2 onions are a pound. meaning 5 onions equal 2 1/2 pounds.
2.5 × 0.79 = $1.975 (about $1.98)
this is area right???
Answer:
Yes
Step-by-step explanation:
So permiter is two*lengths plus 2*width of a shape.
Area is the length times the width.
For examplel if a square has a length of 2, and a width of 3 the permiteter is:
2*2+3*3=
4+9
=
13
On the other hand, area would be:
2*3
=
6
I hope this helps!
I need help with this and also the explanation plz
Answer:
The correct answer is 0 or A
Step-by-step explanation:
2/0+2 + 1/5 = 6/0+5
2/2 + 1/5 = 6/5
1 + 1/5 = 6/5
5/5 + 1/5 = 6/5
6/5 = 6/5
A tire has a circumference of 69.1 inches. To the nearest inch, which is the diameter
of the tire?
Answer:
22 inches
Step-by-step explanation:
so to find the diameter you divide the circumference by pi(3.14)
69.1÷3.14=22.006
now rounding that you get 22
Complete the square to find the vertex of this parabola. x2-16y-4x-12=0
Answer:
Step-by-step explanation:
x^2-16y-4x-12=0
Transpose and separate x and y
16y = x^2-4x-12
16y = (x^2-4x+4) -16
16y = (x-2)^2 -16
y = (1/16)(x-2)^2 -1
This means that the vertex is at
(x-2)=0 or x=2
y = -1
=> vertex (2,-1)

Answer:
[tex]5\sqrt{3}[/tex]
Step-by-step explanation:
A triangle with angles of 30-60-90 will always have sides that measure in the following proportions:
The side opposite the 30* angle = a
The side opposite the 60* angle = [tex]a\sqrt{3}[/tex]
The side opposite the 90* angle = 2a
(I used "a" here because your question uses "x" and I don't want to confuse things, but usually people use "x" rather than "a")
They gave us that the hypotenuse (the side opposite the 90* angle) is 10, from there we can figure out the other sides:
Since the side opposite 90* is 2a, and 2a = 10, divide 10 by 2 and you get a = 5.
Once we know what "a" is, we can fill in the rest:
30* = 5
60* = [tex]5\sqrt{3}[/tex]
90* = 10
Last week, Ann bought 9 books and 5 movies for a total of $124.
Today, Ann bought 4 books and 21 movies for a total of $318.
Assuming neither item has changed in price, what is the cost of a book in dollars?
Answer:
$6
Step-by-step explanation:
Set up a system of equations where b is the cost of a book and m is the cost of a movie:
9b + 5m = 124
4b + 21m = 318
Solve by elimination by multiplying the top equation by -21 and the bottom equation by 5:
-189b - 105m = -2604
20b + 105m = 1590
Add the equations together, then solve for b:
-169b = -1014
b = 6
So, the cost of a book is $6

write an equation that represents the line.
Answer:
y = 2x+5 or -2x+y =5
Step-by-step explanation:
You can use the graph to help you find the solution. You are given your Y intercept as on of the points which is 5. Because you have that you can then count to were your next point is located or use the slope equation [tex]\frac{y2-y1}{x2-x1}[/tex], to find the slope.

A choir teacher is dividing 12 sopranos and 9 altos into singing groups. He wants each group to have the same combination of sopranos and altos, with no singers left over. What is the greatest number of groups he can make?
Answer:
3 groups
Step-by-step explanation:
Sopranos = 12
Altos = 9
Find the highest common factor of 12 and 9
12 = 1, 2, 3, 4, 6, 12
9 = 1, 3, 9
The highest common factor of 12 and 9 is 3
Therefore, the choir teacher can only have 3 groups
12 sopranos / 3 groups
= 4 sopranos per group
9 Altos / 3 groups
= 3 altos per group
Each of the 3 groups Will have 4 sopranos and 3 altos each
87=x+4 in exponential form
Answer:
87=x + 4 x=83
Step-by-step explanation:
87= x + 4
Switch sides
x + 4 = 87
Subtract 4 from both sides
x + 4-4 = 87-4
Simplify
x = 83

What is the volume of a right circular cone that has a height of 19 feet in a base with a diameter of 18.7 feet round your answer to the nearest 10th of a cubic foot
Answer:
A = 1739.4 cubic feet
Step-by-step explanation:
B = area of base (πr²)
h = height
A = Bh/3
A = [(18.7÷2)²π × 19] / 3
A = (9.35²π×19) / 3
A = 1739.4

Number of black cubes = 5
Number of pink cubes = 3
Number of blue cubes = 2
Total number of cubes = 10
The probability of picking a pink cube and then a black cubes will be:
p(pink,blue) = 3/10 × 5/9
= 1/6
The probability is 1/6
