Answer:

x = 55

Step-by-step explanation:

In a rhombus, each diagonal bisects a pair of opposite angles.

For this parallelogram t be a rhombus, the angles with measures 2x - 40 and x + 15 must be congruent.

2x - 40 = x + 15

Subtract x from both sides.

x - 40 = 15

Add 40 to both sides.

x = 55

Answer:

R$49.02

R$49.09

Step-by-step explanation:

Por não pagar a conta em dia, o valor de 2% de juros foi adicionado, o novo valor base passa a ser:

$V = 1.02*48\\V=R\$48.96$

O valor a ser pago n dias após o dia 13 de abril é dado por:

$P=48.96*(1+\frac{0.033}{100} )^n$

No dia 17 de abril, n =4 e o valor a ser pago é:

$P=48.96*(1+\frac{0.033}{100} )^4\\P=R\$49.02$

Caso n =8, o valor a ser pago seria:

$P=48.96*(1+\frac{0.033}{100} )^8\\P=R\$49.09$

Please help Cant figure it out

IrinaVladis [17]

Answer:

Step-by-step explanation:

If a number is to the power of a negative number, then it is just that number's reciprocal: e.g. y⁻ˣ = $\frac{1}{y^{x} }$

Therefore, m⁻² will be m² in the denominator, as n⁻³ will be n³ in the numerator.

That will look like $\frac{3n^{3} }{5m^{2} }$ .

So, that is C.
