Answer:
R$ 27,00
Step-by-step explanation:
R $ 72,00 = Um bolo de morango + dois quilos de bolo de chocalate
Um bolo de morango = R$ 18,00
R $ 72,00 = R$ 18,00 + Dois quilos de bolo de chocalate
Dois quilos de bolo de chocalate = R$72,00 - R$18,00
= R$54,00
Dois (2) quilos de bolo de chocalate = R$54,00
Um (1) quilo de bolo de chocalate = x
2x = R$ 54,00
x = R$ 54,00/2
x = R$ 27,00
Um quilo do bolo de chocolate = R$27,00
Volume is equal to the area of the base times the height in regular 3D shapes.
volume = πr²h = π(6²)10 = 360π = 1131.0 m³ approx.
P = A(1+i)ⁿ, where:
A= initial value
I = interest in %
n= period of compound investment.
However, if the interest is paid twice a year, that means you have to divide the interest by 2 and the period becomes twice n
P = 875(1+9.5%/2)⁵ˣ²
P = 875(1+4.75%)¹⁰
P =875( 1.0475)¹⁰
P = $1,391.7
(mx + 7)(5x + n) = 5mx^2 + mnx + 35x + 7n
= 5mx^2 + (35 + mn)x + 7n
= px^2 + 15x + 14
7n = 14
n = 2
35+mn = 15
35+ m(2) = 15
35+ 2m = 15
2m = 15-35
2m = -20
m = -10
p = 5m
= 5(-10)
=-50
m(n + p) = -10(2 -50)
= 480
No, he got an 80% on the test. 24 divided by 30=0.80
