ABC DEF. Find the length of median CP. please help me out!
Answer:
[tex]CP = 24[/tex]
Step-by-step explanation:
The measured sides are 24 and 32 units long. It means that the larger triangle is [tex]\frac{32}{24} =\frac 43[/tex] times bigger than the smaller one. In particular, all linear measures are scaled of the same ratio: for medians we can write
[tex]FQ= \frac 43 CP \rightarrow 3FQ=4CP[/tex]
At this point we replace both segments with their lengths and solve for x. Once we find x, we can determine the length of CP.
[tex]3(2x+8)=4(3x-12)\\6x+24=12x-48 \rightarrow 6x=72 \rightarrow x=13\\CP = 3(13)-12 =36-12=24[/tex]
The length of the median CP is 24 units if the triangle ABC and triangle DEF are similar, option (C) is correct.
What is the similarity law for triangles?It is defined as the law to prove that the two triangles have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.
The ratio of the sides:
DE/AB = 32/24 = 4/3
Similarly, the ratio of the sides:
QF/CP = 4/3
3QF = 4CP
3(2x + 8) = 4(3x - 12)
6x + 24 = 12x - 48
6x = 72
x = 12
CP = 3(12)—12 = 24 units
Thus, the length of the median CP is 24 units if the triangle ABC and triangle DEF are similar, option (C) is correct.

A field is divided into three senion A, B and C ratio 2:3:5. If section A covers an area 3.5 acres. Calculate the area of field
Answer:
17.5 acres
Step-by-step explanation:
Let the areas of A, B, and C be 2x, 3x, and 5x, respectively,
then 2x = 3.5 acrea, x = 3.5/2 acres
Total area is 2x + 3x + 5x = 10x = 10 * 3.5/2 = 17.5 acres

A line passes through the points (20, 15) and (19, 14) What is its equation in slope-intercept form?
Answer: y = x - 5
Step-by-step explanation:
Slope intercept form is y = mx + b
to find the slope: y2-y1/x2-x1: 15-14/20-19 = 1/1 = 1
so we can write it as y = x + b, (since the slope is 1).
To find b, plug in either point given to the formula:
15 = 20 + b
b = 15 - 20
b = -5
so the completed equation is y = x - 5
Answer:
y = x-5
Step-by-step explanation:
The form of slope intercept is y=mx+b]
To solve :
First you need to find the slope
To find the slope, you the slope equation, which is y2-y1/x2-x1
Since first you put y2-y1 at the top, it would be 14-15 and then 19-20 at the bottom since x2-x1 is put at the bottom.
Your slope equation should be : m=14-15/19-20, which should give you m=-1/-1 with m being 1.
Then you plug in the value in the slope intercept equation
To help us find the y intercepts, lets choose one our points. In this case, we will be using (20,15) since it is the first point.
Slope intercept form is y=mx+b.
we do 15= 1 x 20 +b
15=20+b, gives you b=-5
How you got b=-5:
1)Put the equation into this by switching sides :
1 (20)+b=15
2) Get rid of the parenthases :
1 x 20 + b=15
3) multiply :
1 x 20=20, so
20+b=15
4) On both sides, subtract 20
so it would be
20+b-20=15-20, which gives you b=-5

A notation like - (-6) can be written as +6 ("two times minus is plus").
So your question 10. becomes:
(-19 + 20 + 34) / -6, which is more pleasant to the eye.
Further simplifying gives you 35 / -6 which you should write as -35/6.

Check whether the given ratios are equal
5:7 and 35:49
Step-by-step explanation:
1st ratio=
5:7
[tex] \frac{5}{7} [/tex]
2nd ratio =
35:49
[tex] \frac{35}{49} \\ \frac{7 \times 5}{7 \times 7} \\ \frac{7}{7} \times \frac{5}{7} \\ 1 \times \frac{5}{7} \\ \frac{5}{7} [/tex]
Hence, the ratios are equal
Solution:
Step-1: Convert the ratios into fractions.
5:7 = 35:495/7 = 35/49Step-2: Simplify both sides of the fraction.
~5/7 cannot be simplified because the numerator and denominator are prime number. However, 35/49 can be simplified by dividing 7 to the numerator and the denominator.
35/49 ⇒ 7 x 5/7 x 7 ⇒ 5/7⇒ 5/7 = 35/49
⇒ 5/7 = 5/7 (Yes. They are equal)

don't spam answer only if you know What is the measure of angle x? Enter your answer in the box
Answer:
The angle of x is 83°
Step-by-step explanation:
A straight line has a total of 180°. That means if you can figure out what the third angle on the bottom is (the one in the middle) you can add 41 to it and subtract that from 180. Since all the lines are straight you can say that the middle angle on the bottom is the same as the middle angle on the top. So:
180° - (41° + 56°) = 83°

Answer:
Lori reportedly paid her mother a third of the $39. Now let's see what 1/3 of $39 is.
$13 = 39/1 x 1/3 So she paid $13, but she still owes $23 of the original $39.
So, we need to figure out what 2/3 is, and here's how: 39 - 13 = $26. She owes her mother $26.
As a result, it now indicates that she paid 1/4 of the outstanding debt. Let's see what 1/4 of $26 equals.
6.50 = 26/1 x 1/4 She repaid $6.50 of the $26 she had borrowed. And she still owes 3/4 of what she owes. Let's find out what 3/4 means now. So, remove $6.50 from $26, as follows: 26 - 6.50= $19.50.
Step-by-step explanation: See above.
