sin∅ = opposite over hypotenuseStep-by-step explanation:
Step 1: Define variables
∅ = 39°
opposite leg = 9
hypotenuse = x
Step 2: Solve for x
Substitute: sin39° = 9/xMultiply x on both sides: xsin39° = 9Isolate x: x = 9/sin39°Evaluate: x = 14.3011Round: x ≈ 14.30Related Questions

In the expression, what does the first term represent?
1 Jack's earnings at the end of the week
2 The number of bags of apples Jillian sold
3Jillian's earnings at the end of the week
4 The number of bags of apples Jack sold
Answers
We are given that Jack and Jillian sell apples at a produce stand .
We are given that an expression which shows Jack's earning=2x-8
We have to find that first term what represent in the given expression
Jillian earns for each bag of apples she sells=$2
Let Jillian sold number of bags of apples =x
Then ,Jillian earn total at the end of the week =
Jack has earned $ 8 less than Jillian earn
Therefore, total earning of jack=
In the given expression the first term 2x represent the earning of Jillian.

A tanker truck fills the gas station's reservoir at the rate of 1212 gallons per minute. If the reservoir was empty and it is now 35 gallons full, how long has the tanker been filling the reservoir? Round your answer to the nearest tenth.
Answers
Answer: 2.9 minutes.
Step-by-step explanation:
Given: Rate of filing the tank = 12 gallons per minute
Total volume of reservoir = 35 gallons
Time taken to fill the reservoir = [tex]\dfrac{\text{Total volume of reservoir }}{\text{Rate of filing the tank}}[/tex]
[tex]=\dfrac{35}{12}\approx2.9[/tex]
hence, time taken to fill the reservoir = 2.9 minutes.

Answers
Answer:
∠b = 88 - 5x
Step-by-step explanation:
If a and b are complementary, then sum of two angles is 90
∠a + ∠b = 90
5x + 2 + ∠b = 90
∠b = 90 - 5x - 2
∠b = 88 - 5x
What are the values of the domain in the following graph?
A.the domain is represented by cm/ year
b. The domain is represented by the height of the horse
c. The domain is represented by the age
d. The domain is represented by the average growth of the horse
Answers
Answer:
We conclude that The domain is represented by age.
Thus, the option 'c' is true.
Step-by-step explanation:
We know that the domain of a function is the entire set of input values of the independent variable 'x' for which the function remains real and defined.
Given the attached graph, we can observe that height is dependent on age (years). In other words, the age (years) is basically an independent variable.
Therefore, we conclude that The domain is represented by age.
Thus, the option 'c' is true.
Answer:
C. The domain is represented by the age

A cereal box manufacturer changes the size of the box to increase the amount of cereal it contains. The expressions 16+6.2n and 10+6.5n, where n is the number of smaller boxes, are both representative of the amount of cereal that the new larger box contains. How many smaller boxes equal the same amount of cereal in the larger box?
Answers
Answer:
20 smaller boxes
Step-by-step explanation:
Given
Smaller Box = 10 + 6.5n
Larger Box = 16 + 6.2n
Required
Determine the number of small box in each box
To do this, we simply equate both expressions:
[tex]Smaller\ Box = Larger\ Box[/tex]
[tex]10 + 6.5n = 16 + 6.2n[/tex]
Collect Like Terms
[tex]6.5n - 6.2n = 16 - 10[/tex]
[tex]6.5n - 6.2n = 6[/tex]
[tex]0.3n = 6[/tex]
Make n the subject
[tex]n = 6/0.3[/tex]
[tex]n = 20[/tex]
Hence, there are 20 smaller boxes

Number 3.
In the diagram, AB is the tangent to the circle at P and PX is the diameter.
Given that BPQ = 42°, find PQX, PXQ and XPQ.
Answers
Answer:
see explanation
Step-by-step explanation:
∠ PQX = 90° ( angle in a semicircle )
∠ PXQ = 42° ( alternate angle theorem )
Angle between tangent and diameter is right, thus
∠ XPQ = 90° - 42° = 48°
