Answer:
Step-by-step explanation:
Area of rectangle=width times height
Perimeter of rectangle=width plus width plus height plus height
If you have a rectangle that is 10 units wide and 5 units tall. The area would be 10X5=50units squared and the perimeter would be 10+10+5+5=30 units.
If you multiply the width by 14, everything changes. 10X14 is 140 units. So the width of the rectangle is now 140 units while the height is 5. The area would now be 140X5=700 Units squared and the perimeter would be 140+140+5+5=290 units.
Area of triangle= base time height divided by 2
Perimeter of triangle= side plus side plus side
If its a triangle, let's say a right triangle 10 units at the base and 5 units in height. The area will be 25 Units squared. 10X5=50 divide by 2=25 units squared. If you multiply the base by 14....140X5=700 divide by 2=350.
I didn't figure out the perimeter of the triangle, because I'm being too lazy to figure out the length of the third side.
It has to be the last one, D. I did it over 3 times to make sure.
Answer:
m - n = 501
Step-by-step explanation:
Remark
The first thing you have to do is find the number of odd and even numbers. This is where you have to be careful because there is a danger of being out by one.
equation
l = a + (n - 1)*d
Solution even
l = 1000
a = 2
d = 2
1000 = 2 + (n - 1)*2
998/2 = (n - 1) * 2 / 2
499 = n - 1
n = 500
Solution odd
l = 1001
a = 1
d = 2
1001 = 1 + (n - 1)*2
1000 = (n - 1)*2
1000/2 = (n - 1)2/2
500 = n - 1
501 = n
Sum Even of even numbers from 1 to 1001
Givens
a = 2
n = 500
l = 1000
Equation
Sum = (a + l ) * n / 2
Solution
Sum = (2 + 1000)*500/2
Sum = 1002 * 250
Sum = 250500
Sum of Odd numbers from 1 to 1001
a = 1
l = 1001
n = 501
Equation
sum = (a + l)*n/2
sum = (1 + 1001) * 501
sum = (1002)*501 / 2
Sum = 251001
Answer
m - n = 251001 - 250500 = 501
Answer: about 45
first since there’s 30 miles per gallon multiply 5.3 by 30 and then subtract 120 and there’s the answer
