What is the solution for r in the following system of equations?
2x + 3y = 16
2 + 2y = 10
Answer:
(2,4)
*View attached graph*
Step-by-step explanation:
2x + 3y = 16
2 + 2y = 10
2 + 2y = 10
-2 - 2
2y = 8
/2 /2
y = 4
2x + 3y = 16
2x + 3(4) = 16
2x + 12 = 16
- 12 - 12
2x = 4
/2 /2
x = 2
(x,y) -> (2,4)

Anna sells candy apples at her yard sale. She wants to earn more than $40. She sells the apples for $2 each and has earned $26. How many apples, a, does she need to sell to reach her goal?
Write an inequality to determine the number of apples anna needs to sell to meet her goal.
Solve the inequality.
Graph the solution set on the number line.
Explain the solution set.
please
Answer:
7
Step-by-step explanation:
Because if 1 apple=2$ then she need to sell 20 apples she now has 26$ meaning she has sold 13 of them so 26$
She needs 14 more$ remember the rule 1 apple=2$ so if she needs 14 more $ then that means 7 more apples=14$ And there's your answer 7 more apples.

A 2-column table with 9 rows. The first column is labeled year with entries 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013. The second column is labeled precipitation with entries 5. 98, 6. 05, 07. 59, 5. 27, 3. 11, 7. 18, 2. 95, 7. 22, 2. 61. The table shows the precipitation in December, in inches, for Washington state from 2005 to 2013. What was the mean amount of precipitation during this time? Round to the nearest hundredth. 1. 97 inches 2. 61 inches 5. 33 inches 5. 98 inches.
The mean amount of precipitation from 2005 to 2013 is 5.33 inches.
It is given that
precipitation in 2005 = 5.98 inch
precipitation in 2006 = 6.05 inch
precipitation in 2007 = 7.59 inch
precipitation in 2008 = 5.27 inch
precipitation in 2009 = 3.11 inch
precipitation in 2010 = 7.18 inch
precipitation in 2011 = 2.95 inch
precipitation in 2012 = 7.22 inch
precipitation in 2013 = 2.61 inch
What is the mean value?The mean value is the ratio of the sum of all observations to the number of observations.
Sum of observation = 47.96
Number of observations = 9
Mean = 47.96/9 = 5.33 inches
Therefore mean amount of precipitation from 2005 to 2013 is 5.33 inches.

Make x the subject of the formula Tx/q = y
Answer:
Step-by-step explanation:
To make 'x' as the subject isolate 'x'.
To isolate 'x',
Step 1: Multiply the entire equation by q
Step 2: Then Divide by T
[tex]q*\dfrac{Tx}{q}=q*y\\\\\\Tx=qy\\\\\dfrac{Tx}{T}=\dfrac{qy}{T}\\\\\\x=\dfrac{qy}{T}[/tex]
Answer:
x = qy/T
Step-by-step explanation:
We want to isolate the x term. To do that, first multiply by q to end up with Tx = qy.
Then divide by T to get x = qy/T.
x is by itself, and we have our answer.

Answer:
1920
Step-by-step explanation:
What we can do is split this into two sections: the volume of the rectangle and the volume of the square.
Rectangle: We can follow the equation V = lbh, so we have 14x8x10, giving us 1120.
Square: We can use the same equation, V = lbh, giving us 10x10x8 which is 800.
Final Answer: To get the full volume, we have to add these together, so, 1120 + 800 = 1920.
The function f(x) = 2x2 3 represents the rate of a boat traveling with the current in miles per hour. The function g(x) = x 2 represents the time the boat traveled in hours. Solve (f • g)(2), and interpret the answer. (f • g)(2) = 15, the distance in miles the boat traveled (f • g)(2) = 15, the number of boats (f • g)(2) = 44, the distance in miles the boat traveled (f • g)(2) = 44, the number of boats.
The distance in miles the boat traveled for the modeled function of speed and time is,
[tex](f .g)(2) = 44[/tex]
What is the rate of speed?The rate of speed is the rate at which the total distance is travelled in the time taken.
The function which represents the rate of a boat traveling with the current in miles per hour is,
[tex]f(x) = 2x^2+ 3[/tex]
The function which represents the time the boat traveled in hours is,
[tex]g(x) = x+ 2[/tex]
The distance traveled by boat is the product of rate of speed of the boat and time taken by the boat. Thus, the multiplication function for the above two function can be given as,
[tex](f.g)(x)=(2x^2+3)(x+2)[/tex]
Solve the above function for (f • g)(2) as,
[tex](f.g)(2)=(2(2)^2+3)(2+2)\\(f.g)(2)=(8+3)(4)\\(f.g)(2)=44[/tex]
Interpret the above answer with the given option we get, (f • g)(2) = 44, the distance in miles the boat traveled
Hence, the distance in miles the boat traveled for the modeled function of speed and time is,
[tex](f .g)(2) = 44[/tex]

The scale on a map shows that 1 inch = 30 miles. If there are 4.5 inches between your present location and the place you want to go, how many miles do you have to ?
Scale : 1 inch = 30 miles
So, the ratio between the distance on the map and the real distance is 1:30
When a quantity increase/decrease in a ratio, the other one increase/decrease respectively.
Call the miles we have to go : x
1:30 = 4.5:x
(1x4.5):(30x4.5) = 4.5 : x
4.5 : 135 = 4.5 : x
So, x = 135 => We have to go 135 miles to get to the place we want to go.
Joan made a graph modeling her income and costs for selling x loaves of zucchini bread at the farmers' market.
After examining the graph, Joan determines that she will need to sell 19 loaves of bread in order to break even. Her coworker says that she is not correct, and that Joan actually only needs to sell 18.824 loaves of bread
Is Joan's answer practical in this situation, and why or why not?
A.
Joan's answer is not practical in this situation since the graph intersects below the x-value of 19.
B.
Joan's answer is not practical in this situation since income and costs can be measured in decimal increments.
C.
Joan's answer is practical in this situation since, based on the graph, there is no reason to report a value other than 19 loaves of bread.
D.
Joan's answer is practical in this situation since her costs are more than her income until she sells more than 19 loaves of bread.
The number of bread loves to sell to break even is 19, thus, Joan is practical in this situation, so option D is correct.
What is a graph?A graph is a structure made up of a collection of things, where some object pairs are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.
Given:
Joan determines that she will need to sell 19 loaves of bread in order to break even,
As you see from the graph,
The coordinate of the cost line can be determined by (0, 80) and (11, 110) and the coordinates of the income line can be determined as (0, 0) and (10, 70)
Write the equation of the line as shown below,
y - 80 = 110 - 80 / 11 - 0 (x - 0)
y - 80 = 30 / 11 x
And y = 70 / 10 x
Solve the above equation, you will get the value of x and y,
x = 18.72 and y = 7 × 18.72 = 131.06
Joan can break even when she sold 18.72 of bread, but the bread loaves can't be divided into further pieces, thus she has to sell 19 to break even.

Which angle is a reflex angle? A. An angle measuring 105 . An angle measuring 185 degrees . An angle measuring 65 D. An angle measuring 90 degrees
Answer:
an angle greater than 180° and less than 360°.
Step-by-step explanation:
The correct value of reflex angle is,
⇒ An angle measuring 185 degrees.
What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
To find reflex angle.
Now, We know that;
Reflex angle is greater than 180 degree and less than 360 degree.
Thus, By options;
⇒ 185° > 180°
Hence, The correct value of reflex angle is,
⇒ An angle measuring 185 degrees.
