X = 38°

Step-by-step explanation:

The sum of the inner angles of a triangle is 180 degrees

Then.. :

136+ x= 180

180- 136= x

X= 44

88 + 44 + x = 180

142+ x = 180

X= 180-142

X = 38°

Answer:

(b) 10.5 in

Step-by-step explanation:

The formula for the volume of a cone is ...

V = 1/3πr²h . . . . . . for radius r and height h

Then the height is ...

h = 3V/(πr²)

Your cone has a volume V = 199 in³ and radius r = 4.25 in, so the height is ...

h = 3(199 in³)/(π(4.25 in)²) ≈ 10.52 in

The height of the cone is about 10.5 inches.

Tabitha decided to start saving pennies for a stretch of two months and initially started with 2 pennies. A table showing the nu

Answer:

after week 7: 4374 pennies
486 pennies: after week 5

Step-by-step explanation:

The sequence values have a first term of 6 and a common ratio of 3, so can be described by the formula ...

an = 6·3^(n-1)

This can be rearranged to ...

an = 2·3^n

When n=7, the value is ...

a7 = 2·3^7 = 4374 . . . . pennies saved after 7 weeks

To find when there are 486 pennies saved, we can solve the equation ...

486 = 2·3^n

243 = 3^n

log(243) = n·log(3) . . . . . . . take the logarithm

log(243)/log(3) = n = 5 . . . . divide by the coefficient of n

Tabitha will have saved 486 pennies after 5 weeks.
