64% = $389
___ ____
100% X$ = Cross multiplication. (64x = 38900 = $607.81)
I rounded it.
Hope I become the brainliest answer.
as tiers increases, sales increases
since there seems to be no assemtote (horizontal or vertical), As the number of cake tiers increases without bound, the total monthly sales increase without bound.
answer is 3rd option
Answer:
3(x + 9)(x + 9)
Step-by-step explanation:
- 3x^2 + 54x + 243
- 3(x^2 + 18x + 81)
a + b = 18
a + b = 81
a= = 9, b = 9
3. 3(x + 9)(x + 9)
Answer:
Part 1) The measure of angle d is 65°
Part 2) The measure of angle c is 89°
Part 3) The measure of arc a is 131°
Part 4) The measure of arc b is 47°
Step-by-step explanation:
we know that
In an inscribed quadrilateral, opposite angles are supplementary
step 1
Find the measure of angle d
∠d+115°=180°
∠d=180°-115°=65°
step 2
Find the measure of angle c
∠c+91°=180°
∠c=180°-91°=89°
step 3
Find the measure of arc a
we know that
The inscribed angle measures half that of the arc comprising
115°=(1/2)[99°+arc a]
230°=[99°+arc a]
arc a=230°-99°=131°
step 4
Find the measure of arc b
we know that
The inscribed angle measures half that of the arc comprising
∠c=(1/2)[arc a+arc b]
substitute the values
89°=(1/2)[131°+arc b]
178°=[131°+arc b]
arc b=178°-131°=47°
