Ok, so if the angle is 120 degrees, its one third of the full cake (which is 360 degrees). So the area of the whole circle (worked out with area = pi * r^2 where r is 30) gives 900*pi, and so one third of that (because her slice is one third)  is 300pi.

Jace’s basketball team scored 38 points in the first game of the season. In the next two games they scored a total of 77 points.
tia_tia [17]

Answer:

Jace is wrong

This how you do it: (19 + 77 x (0.5) )

Step-by-step explanation:

Here, for each point scored, $0.5 is put in the jar.

Now, the point scored in the first game  = 38 points

So, the amount put in the jar for 38 points = 38 x ( amount for 1 point)

=  38 x ( $0.5)   = $19

So, after first game, jar has $19.

Now, the point scored in the(2 +3) game  = 77 points

So, the amount put in the jar for 77 points = 77 x ( amount for 1 point)=  77 x ( $0.5)   = 77 x (0.5)

So, after second and third  game, jar has $ (77 x (0.5)).

Now, total amount in jar  

= Amount after first game  + Amount after second and third game

= 19 + 77 x (0.5)

But , here THE TOTAL AMOUNT given by Jace  = 38+(77  x 0.5)

And 19 + 77 x (0.5)  ≠ 38+(77  x 0.5)

$57.5

A can of paint will cover 400 square feet. What is the length of the edge of the largest square that can be painted with this ca
Masteriza [31]
One gallon can of paint will cover up to 400 square feet, which is enough to cover a small room like a bathroom. Two gallon cans of paint cover up to 800 square feet, which is enough to cover an average size room. This is the most common amount needed, especially when considering second coat coverage.

What is the value of x
Crank

Answer:

Step-by-step explanation:

Looking at the diagram,

Line DT is parallel to line line BM, therefore, triangle DHT is similar to triangle BHM. This means that

DH/DB = TH/MH

DH = 15 + 6 = 21

TH = 9 + x

Therefore

(9 + x)/21 = 9/6

Cross multiplying, it becomes

6(9 + x) = 21 × 9 = 189

54 + 6x = 189

Subtracting 54 from the left hand side and the right hand side of the equation, it becomes

6x + 54 - 54 = 189 - 54

6x = 135

Dividing the left hand side and the right hand side of the equation by 6, it becomes

6x/6 = 135/6

x = 22.5
