Hey there!:
According to the Pythagorean theorem, the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse (H):
1² + 19² = x²
1 + 361 = x²
x² = 1 + 361
x² = 362
x = √ 362
x = 19.02
Hope this helps!
Answer:
y = 2.25x
Step-By-Step Explanation:
If I divide y by x, in any of the tables, it is always 2.25.
y ÷ x = 2.25
Then, I can multiply x on both sides to make the equation showing the proportional relationship.
y ÷ x × x = 2.25 × x
y = 2.25x

Answer:
19404
Step-by-step explanation:
sum of arithmetic series is
Sn = n/2 (2a + (n-1)d)
or
Sn = n/2 (a + an)
a = 1st unit
an = last unit
d = difference
8-3 or 13-8 so d = 5
then first step is to find the value of n
an = a + (n-1)d
438 = 3 + (n-1)5
438 - 3 = 5n - 5
435 = 5n - 5
435 + 5 = 5n
440 = 5n
n = 440/5
n = 88
then we can find the sum
Sn = 88/2 (3 + 438)
S88 = 19404
Answer:
76 hamburgers were sold
Step-by-step explanation:
total sold: 228
ratio of cheeseburgers to hamburgers sold: 2:1
2+1=3 to find total of ratio
228÷3= 76 to find the value of 1 part in the ratio
because hamburgers sold was only 1 part, the answer is 76
Answer:
