The perimeter of triangle def similar to triangle abc is 22 cm.
What is Perimeter?Perimeter is the total distance around a object.
Note: The ratio of the perimeters of two similar figures is equal to the ratio of their corresponding side lengths.
To calculate the perimeter of triangle def, we use the formula below.
Formula:
B/B' = P/P'.................. Equation 1Where:
B = Base of triangle abcB' = Base of triangle defP = Perimeter of triangle abcP' = Perimeter of triangle defFrom the question,
Given:
B = 3 cmB' = 6 cmP = 11 cmSubstitute these values into equation 1 and solve for P'
3/6 = 11/P'P' = 6×11/3P' = 22 cmHence, the perimeter of triangle def is 22 cm.

20) If the area of a rectangular playground is
p^2 -6p - 7 square feet, what is the perimeter of the
playground?
Answer:
Explanation:
Write an equation to solve the problem.
Area of rectangle = L(w)
Assuming that the width measures x meters, the length measures x + 5 meters.
500 = x(x + 5)
500 =
x
2
+ 5x
0 =
x
2
+ 5x - 500
As you may already know, a trinomial of the form
a
x
2
+ bx + c, a = 1, you must find 2 numbers that multiply to c and that add to b. Two numbers that multiply to -500 and add to +5 are +25 and -20
0 = (x + 25)(x - 20)
x = -25 and 20
Since a negative length is impossible, the width mesures 20 meters and the length measures 25 meters.

Express the slope as a fraction in lowest terms.
If the slope is undefined, enter undefined into the text box.
m =
Answer:
m = undefined
Step-by-step explanation:
(-9, -17) and (-9, 12)
Slope:
m=(y2-y1)/(x2-x1)
m=(12+17)/(-9+9)
m=29/0
Since 0 is the denominator, the slope is undefined
The triangles shown are similar. Which side of triangle PQR corresponds to side LN in triangle MNL? Triangle L N P. Side L N is 12, N M is 10, M L is 14. Triangle P R Q. Side P R is 28, R Q is 24, Q P is 20. RQ PQ PR LM
Answer:
LN corresponds to RQ
Step-by-step explanation:
If we look at the diagram we find that LN corresponds to RQ, MN corresponds to QP and ML corresponds to PR .
The both triangles are similar as PQR is 2 times of MNL .
Therefore
PQR= 2MNL
PR= 2ML
28= 2(14)
QP= 2MN
20 = 2(10)
RQ =2 LN
24= 2(12)
Answer:
RQ

15 chocolate were distributed between raju and sanju in the ratio 2:3 . How many chocolates did raju receive?
Answer:
6chocolates
Step-by-step explanation:
Given
The total number of chocolate = 15chocolates
If it is divide into ratio 2:3
total ratio = 2+3
Total ratio = 5
Number of chocolate raju receives = 2/5 * 15
Number of chocolate raju receives = 2 * 3
Number of chocolate raju receives = 6chocolates
The number of chocolates that Raju received are; 6 chocolates
ProportionWe are told that;
Number of chocolates distributed = 15
Ratio of sharing between Raju and sanju = 2:3
Thus, fraction to be received by both of them are;
For Raju = 2/(2 + 3) = 2/5For Sanju = 3/(2 + 3) = 3/5Thus;
Amount of chocolates for Rajus = 2/5 × 15 = 6
In conclusion, Raju received 6 chocolates.

Karolyn puts 4,500 into a life insurance policy that pays 7.5% annual interest. If no additional investment is made into the policy how much accumulated interest should Karolyn expect at the end of 10 years?
Answer: $4,774.64
Step-by-step explanation:
The amount after 10 years assuming 7.5% compound interest is:
= Amount * ( 1 + rate) ^ no. of years
= 4,500 * ( 1 + 7.5%)¹⁰
= $9,274.64
The accumulated interest is:
= Amount after 10 years - Present amount
= 9,274.64 - 4,500
= $4,774.64

A triangle has one side that is 5 inches long and another that is 7 inches long. How many different lengths, in inches,are possible for the last side of the triangle?
Answer:
2 < c < 12
Step-by-step explanation:
Let the last side of the triangle = c
The sum of any two sides must be greater than the third side. Let's say we have triangle ABC, where a = 5 inches and b = 7 inches
a + b > c (1)
a + c > b (2)
b + c > a (3)
From (1);
a + b > c
7 + 5 > c
c < 12
From (2):
a + c > b
7 + c > 5
7 - 5 < c
c > 2
From (3):
b + c > a
5 + c > 7
c > 7 - 5
c > 2
So the possible lengths of c are: 2 < c < 12
