What grade level is this?
Answer:
slope = - 4
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = - 1, 22) and (x₂, y₂ ) = (1, 14) ← 2 ordered pairs from the table
m = 
= 
= - 4
The answer is the thousand number which in this case would be 2,000
To solve this problem you must apply the proccedure shown below:
1. You have that t<span>he largest doll is 12 inches tall. The height of each of the other dolls is 7/10 the height of the next larger doll. Therefore, you have:
We don't know the number of dolls, so:
x=12(7/10)^(n-1)
Where x is the height of the doll and n is the number of the doll
The answer is: </span>x=12(7/10)^(n-1)
Answer:
Find the perimeter of the quadrilateral with sides 5 cm, 7 cm, 9 cm and 11 cm.
Solution:
The formula to find the perimeter of the quadrilateral = sum of the length of all the four sides.
Here the lengths of all the four sides are 5 cm, 7 cm, 9 cm and 11 cm.
Therefore, perimeter of quadrilateral = 5 cm + 7 cm + 9 cm + 11 cm
= 32 cm
2. The perimeter of the quadrilateral is 50 cm and the lengths of three sides are 9 cm, 13 cm and 17 cm. Find the missing side of the quadrilateral.
Solution:
Let the missing side of the quadrilateral = x
Perimeter of the quadrilateral = 50 cm
