Answer: 21 states
Step-by-step explanation:
Since, The total number of states in the continental United States is 48 in which some are in the border of ocean and some are not in the border of ocean.
According to the question,
The ratio of the states having the border to the ocean and not having the border to the the ocean = 7 : 9
Let the states having the border to the ocean = 7x
The the states do not having the border to the ocean = 9x
Thus, 7x + 9x = 48
⇒ 16 x = 48
⇒ x = 3
Thus, the states having the border to the ocean = 7 × 3 = 21
In the continental United States, the number of states that border an ocean is 7/16 of the total number of states.
To find the number of states that border an ocean, we need to determine the specific values that correspond to the ratio. Let's denote the number of states that border an ocean as 7x and the number of states that do not border an ocean as 9x, where x is a common factor.
According to the given ratio, the equation is:
7x : 9x
To simplify the ratio, we can divide both sides by x:
7 : 9
Now, we can analyze the ratio. Since it is stated that the ratio applies to the continental United States, the total number of states is irrelevant. We are only concerned with the proportion of states that border an ocean to those that do not.
Based on the simplified ratio of 7:9, we can conclude that out of every 16 states, 7 of them border an ocean while the remaining 9 do not.
Therefore, in the continental United States, the number of states that border an ocean is (7/16) of the total number of states.

Step-by-step explanation:
because it has two zeros
The cost , in dollars, for 3 pounds of oranges is 1.8
Solution:
Given that Monica paid 3.20 for 2 pounds of apples and 2 pounds of oranges
Sarah paid 4.40 for 2 pounds of apples and 4 pounds of oranges.
Let the cost of orange per pound = x
Let the cost of apple per pound = y
Therefore, we can frame an equation as follows for Monica and Sarah:
In Monica’s case:
2x + 2y = 3.20
Hence x + y = 1.6 ---- eqn 1
In Sarah’s case:
4x + 2y = 4.40
Hence 2x + y = 2.2
y = 2.2 -2x – eqn 2
Substitute eqn 2 in eqn 1 we get,
x + 2.2 -2x = 1.6
-x = 1.6-2.2 = -0.6
x = 0.6
Substituting the value of “x” in eqn 2 we get the value of “y” as 1
Thus the cost of orange per pound is 0.6
Therefore, cost of 3 pounds of oranges = 3 × 0.6 = 1.8
Answer:
Trapezoid.
Step-by-step explanation:
Given that Mason drew a quadrilateral with only one pair of opposite sides that are parallel
We know that a quadrilateral is a closed region bounded by four lines called sides with four angles totalling 360 degrees.
Some special types of quadrilaterals are squares, rectangles, parallelograms, trapezoids, etc.
When all four sides and four angles are equal square. When only angles are equal, rectangle. When all four sides are only equal, rhombus. A trapezium is a quadrilateral with only one pair of sides parallel
Hence here what Mason drew is a quadrilateral.
