Katie invested a total of ​$4000​, part at 2​% simple interest and part at 3​% simple interest. At the end of 1​ year, the inves
Fiesta28 [93]

Answer:

$3000

$1000

Step-by-step explanation:

the formula for simple interest = principal x time x interest rate

let the amount invested in the 2% investment be a

let the amount invested in the 3% investment be (4000 - a)

(a x 0.02 x 1) + ([4000 - a] x 0.03 x 1) = $90

0.02a + 120 - 0.03a = 90

Collect like terms and solve for a

0.01a = 30

a = $3000

The amount invested in the 3% investment be (4000 - a)  = $4000 - $3000 = $1000

what property is illustrated by the statement 1×y=y? A. MULTIPLICATIVE IDENTY B. COMMUTATIVE C. ASSOCIATIVE PROPERTY OF MULTIPIL
vesna_86 [32]

This has nothing to do with zero. It is not mentioned at all. If y = 0 then D would apply, but no such restriction is present. The answer is not D

There has to be 3 numbers multiplied together to use the associative properties of multiplication as in (2 * 3) * 5 = 2 * (3 * 5) . The order that we multiply does not matter.

The commutative property could be true, and it is you second best answer (believe it or not) but, 1 * y = y * 1 is kind of trivial. So don't pick B until we find out about A

This often shows up 1 * x is the same thing as x. This is called the multiplicative identity.

A. <<<< Answer.

Which expression is equivalent to (32−−√5)13 ?
Nimfa-mama [501]

Answer:

the given expression is equivalent to the 3 \frac{2}{15}

Step-by-step explanation:

The computation is shown below:

3^2 \frac{1}{5} : 3 \frac{2}{5} \\\\(3\frac{2}{5})^\frac{1}{3}  \\

Now applied the exponent rule i.e. presented below:

(a^b)^c = a^{bc}

= 3 \frac{2}{5} \times \frac{1}{3} \\\\\frac{2}{5} \times \frac{1}{3} \\\\= \frac{2}{15}

3 \frac{2}{15}

Hence, the given expression is equivalent to the 3 \frac{2}{15}
