Answer:
Option A - 
Step-by-step explanation:
Given : Aricela is trying to estimate the distance between her house and the park. On a map with a scale of 0.5 in. = 2 miles, the distance between her house and the park is 2.75 in.
To find : Which proportion can Aricela use to determine the distance, d, between her house and the park?
Solution :
The distance between her house and the park is 'd' miles.
A scale of 0.5 in. = 2 miles
The distance between her house and the park is 2.75 in.
i.e. the scale is 2.75 in. = d miles
The proportion form is
Therefore, proportion can Aricela use to determine is .
So, option A is correct.
0<x<1 and 0<y<1
x>0 so x is positive and y>0 so y is also positive.
When you multiply two positive numbers you always get a positive number, so the product of x and y must be positive, or greater than 0.
xy>0 - it must be true
xy<0 - it can't be true
Also when you divide a positive number by a positive number you always get a positive number, so the quotient of x and y must be positive.
x/y<0 - it can't be true
D and E can be true, but don't have to. It depends on the values of x and y. If x>y, then x-y>0 is true and x-y<0 isn't true; if x<y, then x-y>0 isn't true and x-y<0 is true.
Therefore, only A <u>must</u> be true.
The value of the median is going to be 6
Answer:
A = 4 in²
Step-by-step explanation:
Given 2 similar figures with sides in ratio a : b , then
ratio of areas = a² : b²
here ratio of sides = 3.5 : 14 = 1 : 4 , then
ratio of areas = 1² : 4² = 1 : 16
That is the area of the larger pentagon is 16 times the area of smaller , so
area of smaller A = 64 ÷ 16 = 4 in²
If you would like to know what is 25 percent of 225, you can calculate this using the following steps:
25 percent of 225 = 25% * 225 = 25/100 * 225 = 56.25
Result: 25 percent of 225 is 56.25.
