Points J and Kare midpoints of the sides of triangle

What is the value of y
Answer:
7
Step-by-step explanation:
As we can see, the sides of the bigger triangle is twice that or the smaller
Thus, we have it that for similar sides, we simply have to multiply the smaller side length by 2 to give the larger
We have this as:
2(2y + 5) = 5y + 3
4y + 10 = 5y+ 3
5y-4y = 10-3
y = 7

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.
What is the volume of the cone in terms of pie
Answer:
The formula is the area of the base times the one third of the height. You need to find one third of the height. Then multiply it by 8. "In terms of pi" just means you leave the pi symbol beside your number instead of actually multiplying it.
Step-by-step explanation:
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
12.39 = r
So, the radius of the sphere is approximately 12.4 cm
Convert 6 (whole number) 8/11 to a decimal 
Answer:
6.73
Step-by-step explanation:
6 (whole number) 8/11 is 6.7272 approximately 6.73 (3 s.f)
the 6 whole number gives the 6.
8/11 is 0 and using the whole long division method gives 0.7272...
cause when you add zero to 8 it becomes 80 and 11 goes into 80, 7 times giving 77.
subtracting 77 from 80 gives 3 adding 0 becomes 30 and 11 into 30 is 2 giving 22
I hope this helps

In order for the data in the table to represent a linear
function with a rate of change
of -8, what must be the
value of a?
O a= 2
O a = 3
A
O a = 19
O a = 35
Answer:
a = 19
If the rate of change is -8, everytime you do up for x you will minus 8. For example, x = 10 so y = 27 ; x=11 so y = 27-8 = 19 ; x = 12 so y = 19-8 = 11.
Therefore, when x is 11; y is 19
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
Hope this helped! :)
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.

A car had a value of $10,000 and depreciates at a rate of 7% a year. What is the cars value after 3 years.
Answer:
Step-by-step explanation:
The exponential decay function is
[tex]v(t)=a(b)^t[/tex] where a is the initial value of the car, b is the rate of decay, and t is the time in years. Our rate of decay can also be written as (1 - r) where r is the depreciation in decimal form. Our equation looks like this:
[tex]v(t)=10000(1-.07)^t[/tex] which simplifies to
[tex]v(t)=10000(.93)^t[/tex] Now we can solve our problem for any number of years you'd like. We've been tasked to find the value of the car after 3 years, so:
[tex]v(t)=10000(.93)^3[/tex] which simplifies a bit to:
[tex]v(t)=10000(.804357)[/tex] so
v(t) = 8043.57

The table below shows the amount of money Trista earns working different numbers of
hours. Which expression shows how much money Trista earns for working 8 hours?
Answer:
8*8
Step-by-step explanation:
Hre we can divide the time worked (hrs) by the amount made!
Generally I wouldn't do this for the whole table, but considering its not very big we will!
$16/2hrs =8
$24/3hrs = 8
$40/5hrs = 8
From this we can deduce that every hour, 8 dollars are earned.
The equation would be x=8h
but for this 8dollars * 8 hrs is right!
