Answer:
Area =100 in^2
Step-by-step explanation:
scale factor of the triangles is :15/21=5/7
if two similar shape has a scale factor a/b then the area is a^2:b^2
area of first shape/area of second shape=5/7
x/196=(5)²/(7)²
49x=4900
x=4900/49=100
area=100
check: 100/196=25/49=a^2/b^2
i hope it is right
Answer:
The maximum value of N-M will be 792
Step-by-step explanation:
For N - M to be maximum
N must be very large and M must be very small
largest 3 numbers occur in 900's and smallest 3 digit numbers occur in 100's
so we need such an N which starts with 9 and ends with 1 so that on reversing it produces a number starting with 1.
If N = 901 , M will be 109
N - M = 792
This is the largest possible value of N - M
All other values of N-M will give a smaller value than 792.
Option a. option a has an answer of x=13, while the other problems have solutions of x=5.
Answer:
(a) The monthly budget for housing would range from $2,291.50-$2,749.80.
the good estimate would be $2,566.48.
(b) The monthly budget for housing would range from $1,250-$1,500.
the good estimate would be $1,400.

Answer:
Width=5 Length=10
Step-by-step explanation:
Because we find perimeter by Length + Width x 2, in order to find out the width and the length, we need to remove x2. After that, we get fifteen because we divided thirty by 2. We then need to divide 15 by 3 because we need 1/3 of 15 (whatever that may be) for the width and the we need double of the width for the length which would be 2/3. 1/3 of 15 =5. When you double that, you get 10 for length. So width=5 and Length=10.
