Leroi and Sylvia both put $100 in a savings account. Leroi decides he will put in an additional $10 each week. Sylvia decides to
kati45 [8]
Leroi’s account

$100
After first deposit = $100+$10=$110
After second deposit= $110 + $10 = $120


Sylvia’s account

$100
10% of $100 is $10
After first deposit = $100+ $10 = $110
10% of $110 = $11
After second deposit = $110 + $11 = $121

Therefore after their first deposit, both will have the same value in their accounts.
But after the second deposit, Sylvia will have 1$ more in her account than Leroi.

Find the value of x. Show work if you can
vova2212 [387]

Answer:

Step-by-step explanation:

number of side = n =7

Sum of all the angles of  given polygon = (n -2)*180 = 5 *180 = 900

x + 140 +133 +145 + 117 + 119 + 125 = 900

                                             x +  779 = 900

                                                    x     = 900 - 779

x = 121

There are 180 degrees in a triangle

4. 38+38= 76 degrees

180-76=104

Isosceles, Obtuse

5. 65+ x+x=65

Well we know one of the x

It is 90 degrees because it is a right angle

65+90=155

180-155=25

Scalene, Right triangle

6. 71+45= 116

180-116=64

7.  Scalene, acute

8. 126+22=148

180-148=32

Scalene, Obtuse

9. 50+90=140

180-140=40

Right angle,  Scalene

Please let me know if i got anything wrong

Classify the triangle as acute, right, or obtuse based on the side lengths of 8, 11, and 14.
ratelena [41]

Answer:

Obtuse

Step-by-step explanation:

8^2+11^2=14^2\\64+121=196\\185=196

Since the hypotenuse is bigger, the triangle is obtuse
