Step-by-step explanation:
Answer:
The cost for 1 necklace is $3.
Step-by-step explanation:
With the information provided, you can say that the amount spent in bracelets and necklaces is equal to the price per bracelet for the number of bracelets plus the price per necklace for the number of necklaces, which is:
c=3x+2y, where:
c is the total cost
x is the price per bracelet
y is the price per necklace
Now, you can say that c=21 and x=5 and solve for y to find the price per necklace:
21=(3*5)+2y
21=15+2y
21-15=2y
6=2y
y=6/2
y=3
According to this, the answer is that the cost for 1 necklace is $3.
Answer:
a = 8
b = 4√5
Step-by-step explanation:
Corresponding sides of similar triangles are proportional.
short side/long side = a/16 = 4/a
a² = 64 . . . . . . multiply by 16a
a = 8 . . . . . . take the square root
__
hypotenuse/short side = b/4 = 20/b
b² = 80 . . . . . . . multiply by 4b
b = 4√5 . . . . . take the square root
_____
<em>Additional comment</em>
These relations for the right triangle can be summarized by the rule "the length of a segment that touches the hypotenuse is the geometric mean of the two hypotenuse segments it touches." In the case of b, that means ...
b = √((4)(4+16)) = 4√5
The same sort of relation applies to the unmarked vertical segment on the left:
c = √((16)(16+4)) = 8√5
And, we saw ...
a = √((4)(16)) = 8
Of course, if this rule is to make sense, you need to know that the geometric mean of two numbers is the square root of their product. (In general, the geometric mean of n numbers is the n-th root of their product.)
The combination can be
- 20 Blueberry, 24 chocolate, 16 strawberry
- 10 Blueberry, 12 chocolate, 8 strawberry
- 5 Blueberry, 6 chocolate, 4 strawberry
<h3>What is factor?</h3>
A factor is a number that is multiplied by another number to produce the desired result. The answer to a multiplication puzzle is a product. Imagine multiplying the factors in a multiplication problem to get the answer. For instance, the factors 2 and 4 add up to 8: Just two factors or a great many factors can affect a number.
Total Number of Factors for N = (a+1) (b+1) (c+1) is the formula for the total number of factors for a given number.
given:
Type Number of muffins
blueberry 40
Chocolate 48
Strawberry 32
So, muffins need to be divided equally into separate gift baskets with the same number of each type of muffins in each basket.
The possible condition can be
2 gift basket
20 Blueberry, 24 chocolate, 16 strawberry
4 gift basket
10 Blueberry, 12 chocolate, 8 strawberry
6 gift basket
5 Blueberry, 6 chocolate, 4 strawberry
