Lesson 1 Data Problem:
John has to complete a research project on the ape population in Spain. He is trying to estimate the size and population of apes. He randomly catches 37 apes and marks them with paint. He releases the apes Into jungle. The following year he observes 250 apes and he found that 10 were marked with the paint that he used.
Find out the best estimate for the size of the ape population?

The lengths of the sides of a triangle are in the extended ratio 4:7:10. The perimeter of the triangle is 105 cm. What are the lengths of the sides?
=========================================================
Explanation:
The sides are in the ratio 4:7:10
This scales up to 4x:7x:10x showing that the sides are 4x, 7x and 10x. The variable x is some positive real number.
Add up the sides and set this equal to the given perimeter 105. Solve for x.
4x+7x+10x = 105
21x = 105
x = 105/21
x = 5
This value is then plugged into each side
4x = 4*5 = 207x = 7*5 = 3510x = 10*5 = 50The triangle has sides of 20 cm, 35 cm, and 50 cm.
Note how the ratio 20:35:50 reduces to 4:7:10 after dividing all three parts by the GCF 5. Also, we can see that 20+35+50 = 105 to fully confirm our answer.
I got everything but 10 and 11 this is so confusing

#10.
If the two triangles are similar, then their sides are proportional.
EC we know immediately. If the whole side BC = 12 = BE + EC, and BE is 4, then EC = 8.
Therefore, I can say that BD / (BD + DA) = BE / (BE + EC). To solve the problem for side DA, x will be used in place of DA.
8 / (8 + x) = 4 / (4 + 8)
8 / (8 + x) = 4 / 12 || Cross-multiply
4(8 + x) = 12 * 8
32 + 4x = 96
4x = 64
x = 16
AD = 16
Then, if we know AD, we can easily find AB. AB = AD + DB. AB = 24.
Lastly, we need to find AC. All of the other lengths on the big triangle have been double that of the smaller triangle, so 6 x 2 = 12. AC = 12.
#11.
BC will be parallel to DE if the proportions are equal.
AE / AB = AD / AC
1 / 5 = 2 / 11
These fractions are not equivalent, therefore BC and DE are not parallel.
Hope this helps!! :)

What is the slope of the line with the equation y +2 = -3(x – 7)?
OA.m = -3
O B. m = 3
O C. m = 2
O D. m = -7
Answer:
A.m = -3
Step-by-step explanation:
This equation is written in point slope form
y-y1 = m(x-x1)
y +2 = -3(x – 7)
y - -2 = -3(x – 7)
The slope is -3 and the point is (7, -2)
Given: Right triangle ABC with altitude Line segment C D
Prove: a2 + b2 = c2
Triangle A B C is is shown. Angle A C B is a right angle. Altitude h is drawn from point C to point D on side A B to form a right angle. Line segment A D is labeled e, line segment D B is labeled f, side A B is labeled c, side B C is labeled a, and side A C is labeled b.
Complete the paragraph proof.
You can use the similar triangles formed by the altitude to write ratios for corresponding sides. Using ratios from the large and medium triangles, StartFraction c Over a EndFraction =
. This can be rewritten as
= a2. Using ratios from the large and small triangles,
= StartFraction b Over e EndFraction. This can be rewritten as b2 = ec. By substitution, a2 + b2 =
. You can then factor as a2 + b2 = c(f + e). From the large triangle, you know (f + e) =
. So, a2 + b2 = c2 by using substitution.

3x – 7 y = -27
16x - 5y = 0
(using the linear equation system and solving for x,y)
Answer:
x=5 and y=6
Step-by-step explanation:
Step: Solve 3x−7y=−27 for x:
3x−7y=−27
3x−7y+7y=−27+7y
3x=7y−27
[tex]\frac{3x}{3} =\frac{7y-27}{3}[/tex]
[tex]x=\frac{7}{3} y-9[/tex]
Step: Substitute [tex]\frac{7}{3}y-9[/tex] for x in 6x−5y=0:
6x−5y=0
[tex]6(\frac{7}{3}-9)-5y=0[/tex]
9y−54=0
9y−54+54=0+54
9y=54
[tex]\frac{9y}{9} =\frac{54}{9}[/tex]
Therefore y=6.
Step: Substitute 6 for y in x= [tex]\frac{7}{3} y-9[/tex]:
[tex]x=\frac{7}{3} y-9[/tex]
[tex]x=\frac{7}{3}(6)-9[/tex]
Therefore x= 5.
x= 5 and y= 6

I need help finding y
Answer:
y = 9.8995
Step-by-step explanation:
This question requires the use of basic trigonometry.
In this problem, we know one of the sides and two of the angles.
Since one of the angles is 45 degrees and the sum of all internal angles of a triangle is 180 degrees, the other angle can only be 45 degrees, making this an isosceles triangle - that is, the length of the other leg, x, is also 7.
You could use the soh cah toa mnemonic to figure it out, but here just using the a^2 + b^2 = c^2 should be sufficient since we know both legs of the triangle.
7^2 + 7^2 = 98, and the square root of 98 gives you about 9.8995, which sounds about right for this situation.
Hope this helped!

What is the radius of a sphere with a volume of 7961 cm", to the nearest tenth of a
centimeter?
Answer:
12.4 cm
Step-by-step explanation:
Use the sphere volume formula, V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³
Plug in the volume and solve for r, the radius:
V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³
7961 = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³
1900.55 = r³
