Answer:
yes it's on a 1.5 scale factor.....I think. The question you put at the top threw me off at first but the picture makes sense. I'm not entirely sure if this is right but if you adjust the triangle to be the same way as the other one then you will see which sides correspond to each other. Each number can be multiplied by 1.5 to get the number that is on the side of the other triangle that corresponds with it....if that makes any sense

Lesson 15 Homework 5.2
3. String A is 35 centimeters long. String B is 5 times as long as String A. Both are necessary to create a
decorative bottle. Find the total length of string needed for 17 identical decorative bottles. Express your
answer in meters.

Answer:
The total length of string needed for 17 identical decorative bottles is 35.70 meters
Step-by-step explanation:
Let us solve the question
∵ String A is 35 centimeters long
∵ String B is 5 times as long as String A
→ Multiply the length of A by 5 to get the length of B
∴ The length of string B = 35 × 5 = 175 cm
∵ Both are necessary to create a decorative bottle
∴ The length needed for 1 bottle = 35 + 175 = 210 cm
∴ Each bottle needs 210 cm to be decorated
∵ There are 17 identical bottles
→ Multiply the length needed for 1 bottle by 17
∴ The total length needed = 17 × 210 = 3570 cm
∴ The total length needed to decorate 17 bottles is 3570 cm
∵ 1 meter = 100 centimeter
→ Divide the total length by 100 to express it in meters
∴ 3570 cm ÷ 100 = 35.70 m
The total length of string needed for 17 identical decorative bottles is 35.70 meters

must be an odd number?
a. 5,000
b. 4,500
c. 3,600
d. 500
Answer:
BStep-by-step explanation:
How many four-digit personal identification numbers (PIN) are possible if the PIN cannot begin with a 0 and the PIN must be an odd number?
ANSWER B: 4,500
The number of 4 digit personal identification numbers (PIN) is 4500
What is a PIN?A PIN is a security code that is used for verifying identities
There are 10 numerical digits i.e. 0 - 9
Since the 4 digit personal identification numbers (PIN) cannot begin with 0, then the first character can take any of 9 digits
The other three characters can take any of the 10 digits.
So, the number of PIN is:
PIN = 9 * 10 * 10 * 10/2
Expand
PIN = 4500
Hence, the number of 4 digit personal identification numbers (PIN) is 4500

Answer:
5
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
We will use the KFC method to figure out the answer:
3/5 ÷ 2/1
We keep the first fraction
3/5 ÷ 2/1
Flip the last fraction (swap the numbers)
3/5 ÷ 1/2
Change the sign (to a multiplication symbol)
3/5 x 1/2
Then, finally, to solve for the answer, we multiply across (3 x 1 and 5 x 2).
3 x 1 = 3
5 x 2 = 10
The answer is 3/10 because it cannot be simplified any further.
