Answer:
The given number in standard form would be 5000.
The given number in unit form would be 5 thousands.
Step-by-step explanation:
Given : Expression
To find : The unit form and standard form of the expression ?
Solution :
First we solve the expression,
5 hundred = 500
So,
Therefore, The given number in standard form would be 5000.
The unit form is writing a number using place value units.
In the number 5000 it has 0 ones, 0 tens, 0 hundreds and 5 thousands.
Therefore, The given number in unit form would be 5 thousands.
Here is Triangle A. Lin created a scaled copy of Triangle A with an area of 72 square
units.
C.What is the length of the bottom side of the scaled copy?
Please hurry
Answer:
The length of bottom side of the scaled copy is 12 u
Step-by-step explanation:
To solve this problem we have to know that to calculate the area of a triangle we use the following formula
a = area
b = base
h = height
a = b * h
In the triangle A the base and the height are equal to 3
b = h
Now that we know that b & h we can calculate the base of the scaled copy
72 u² = b * b
72 u² = (b)²
√(72 u²) = b
12 u = b
The length of bottom side of the scaled copy is 12 u
To find the length of the bottom side of the scaled copy of Triangle A, we need to find the scaling factor which is the square root of the ratio of the areas of the scaled copy and the original triangle. The length of the bottom side of the scaled copy is 8 times the length of the bottom side of the original triangle.
To find the length of the bottom side of the scaled copy of Triangle A, we need to find the scaling factor. The scaling factor is the square root of the ratio of the areas of the scaled copy and the original triangle. Here, the area of the scaled copy is given as 72 square units. Let's assume the scaling factor as 'k'. So the area of the scaled copy is k^2 times the area of the original triangle. Therefore, we have the equation k^2 = 72.
Taking the square root of both sides, we get k = sqrt(72).
So the length of the bottom side of the scaled copy is 8 times the length of the bottom side of the original triangle.
#SPJ2
insurance with her remaining savings?
Answer:
3 full years
Step-by-step explanation:
First figure how much she has left over.
15,000-12700=2300
Each year insurance costs $600.
$2300/600 = 3.8
She almost has 4 years but can't quite pay the 4th year so the answer is 3 years.
Answer:
24 piano lessons
Step-by-step explanation:
$0.18: One time
$4.32: ? times
You have to divide 4.32 by 0.18 which will give you 24. So Jennifer practiced 24 times. :)
I hope that helps! :D
P.S. I don't know how you're supposed to do it (i.e. proportions, ratios, etc.), so that's why I did it the way I learned. I just want to say: there are more ways to do this problem. :)
