Answer:
$0.75
Step-by-step explanation:
Given that
Number of bags of popcorn bought = 4
Total money spent = $3.00
To find:
Unit rate per bag of popcorn = ?
i.e. price of one bag of popcorn is to be find out.
Solution:
We can use ratio here to find the rate of one bag of popcorn.
4 bags bought at $3
4 bags : $3
Let us divide both the sides with 4.
bags : $
OR
1 bag bought at $ 0.75
We can alternatively use unitary method.
4 bags are bought at $ 3
1 bag is bought at $
1 bag is bought at <em>$0.75.</em>
<em></em>
So, unit rate per bag of popcorn is <em>$0.75.</em>
Answer:
A(10,-2).
Step-by-step explanation:
It is given that, on a coordinate plane, a triangle has points A'(-2, 10), B'(-6, 4), and C'(-10, 8).
We need to find the pre-image of vertex A' if the image shown on the graph was created by a reflection across the line y = x.
If a figure reflected across the line y=x, then
It is given that A'(-2,10).
On comparing both sides, we get
Therefore, the coordinates of preimage of A' are (10,-2).
Answer:
Therefore the value of tangent of ∠ is
°.
Step-by-step explanation:
Given that,
In Δ, ∠
°,
and
and we have to find the value of tangent of ∠
Diagram of the given triangle is shown below:
Now,
Δ is a right angle triangle, so we can use all the trigonometric ratio.
=
tangent of ∠ =
=
=
=
∴∠ =
= ° ≅
°
Therefore the value of tangent of ∠ is
°.
Let the price of 1 shirt be represented by = s
A pair of pants costs twice as much as a shirt, then the cost of pants is = 2s
The total cost of 1 pair of pants and 1 shirt is $18 , means :
Solving this we get,
So, the price of 1 shirt is $6 and price of 1 pair of pants is = 2s = 2*6 = $12.
