Answer:
15x² - 3x - 7
Step-by-step explanation:
(12x² + 2x) - (-3x²+ 5x + 7)
First open the parentheses by applying the distributive property.
To do this, multiply each term you have inside (-3x⅔ + 5x + 7) by -1.
Thus, you would have the following:
12x² + 2x + 3x² - 5x - 7
Add like terms
12x² + 3x² + 2x - 5x - 7
15x² - 3x - 7
the number of squirrels in a park at the end of the month
Using the given recursive function, we have that:
a) There will be 132 squirrels in the park at the end of August.
b) As time goes by, the number of squirrels in the park will increase.
What is the recursive function for this problem?
The recursive function for this problem models the number of squirrels in the park at the end of month n+1, considering the amount present at the end of month n, as follows:
[tex]S_{n+1} = 1.6S_n - 30[/tex]
For this problem, we have that at the amount at the end of May is of 70, hence:
[tex]S_{5} = 70[/tex]
Hence, we find the amounts at the end of June, July and August, as follows:
[tex]S_6 = 1.6(70) - 30 = 82[/tex].[tex]S_7 = 1.6(82) - 30 = 101[/tex].[tex]S_8 = 1.6(101) - 30 = 132[/tex].Hence:
a) There will be 132 squirrels in the park at the end of August.
b) As time goes by, the number of squirrels in the park will increase.

The set for a school play needs a replica of a historic building painted on a backdrop that is 20 feet long and 16 feet high. The actual building measures 320 feet long by 256 feet high. A stage crewmember writes (x, y) arrow right ( 1/20 x, 1/20y) to represent the dilation. Is the crewmember's calculation correct if the painted replica is to cover the entire backdrop? Complete the explanation.
Answer:
Stage crewmember's calculation is incorrect
Correct = 1/16x 1/16y
Step-by-step explanation:
Given that:
Dimension of backdrop : 20 feets long ; 16 feets high
Actual dimension of building : 320 feets long ; 256 feets high
The correct scale factor can be obtained thus :
Ratio of backdrop dimension to the actual dimension of building
Length : 20 / 320 = 1 /16
Height : 16 / 256 = 1/16
Hence, stage crewmember's calculation of (1/20x ; 1/20y) is incorrect.

Step-by-step explanation:
5x+5y = 10 and 2x+2y=4
0 = 0
3x-6y = 4 and - 4x+8y=7
0 = 37 / 3
6x+2y = 6 and 7x+3y=9

The ratio of sixth-grade students to fifth-grade students in the Kirkpatrick Elementary school band is 5:4. If there are 20 fifth-grade students in the band how many sixth-grade students are in the band?
Answer: 25 sixth graders
Step-by-step explanation:
Sixth-graders are in a ratio with fifth graders in the band at 5:4 and there are 20 fifth-grade students in the band.
To find the number of 6th graders, use direct proportion and assume the sixth grader number is x:
5 : 4
x : 20
4x = 100
x = 100 / 4
x = 25 sixth graders
Luis is 0.25 meters shorter than Harry, if Luis is 1.7 meters tall determine Harry’s height.

In ABC, b = 68 inches, B=65° and C=93º. Find the length of a, to the nearest
inches
Answer:
28inches
Step-by-step explanation:
∠A + ∠B + ∠C = 180°
∠A + 65° +93° = 180°
∠A + 158° = 180°
∠A= 180°-158° = 22°
Using Law of Sines
a/sinA= b/sinB
a/sin22= 68 inches/sin65
a/sin22 = 68/0.9063 = 75.03
a = 75.03 x sin 22
a = 75.03 x 0.3746 = 28.106238≈28 inches

Number of times 3 or 4 will occur
First, we complete the table as follows:
[tex]P(1) + P(2) +......+P(6) =1[/tex]
[tex]0.13 + 0.05 + P(3) + 0.21 + 0.19 + 0.3 = 1[/tex]
Collect Like Terms
[tex]P(3)= 1 -(0.13 + 0.05 + 0.21 + 0.19 + 0.3 )[/tex]
[tex]P(3)= 0.12[/tex]
The expected number of times is:
[tex]E(x)= n * P(x)[/tex]
So, we have:
[tex]E(x) = 300 * (0.12 + 0.21)[/tex]
[tex]E(x) = 300 * (0.33)[/tex]
[tex]E(x) = 99[/tex]
You have 84 feet of streamers. You cut 24 pieces that are each 1/2 yard long. How many feet of streamers do you have left?
Answer:
48
Step-by-step explanation:
If we have 84 feet of streamers. You cut 24 pieces that are each 1/2 yard long then 48 feet of streamers we left.
What is Unit of Measurement ?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
Given that we have a 84 feet of streamers.
You cut 24 pieces that are each 1/2 yard long.
Need to find the feet of streamers we left.
We know that 1 yard is equal to 3 feet.
Therefore, 1/2 yard is equal to 1.5 feet.
The total length of the streamers that were cut is:
24 pieces x 1.5 feet/piece = 36 feet
To find out how much streamer is left, we can subtract the length of the cut streamers from the total length we started with:
84 feet - 36 feet = 48 feet
Therefore, you have 48 feet of streamers left.
