You are choosing between two plans at a discount warehouse. Plan A offers an annual membership fee of $120 and you pay 80% of th

iogann1982 [59]

Let $A be the cost of $q of merchandise under plan A and similarly $B under plan B.
A=120+0.80q, B=40+0.90q
When A=B, 120+0.80q=40+0.90q, 80=0.10q, q=80/0.10=$800.
So you would need to buy $800 of merchandise.
A=B=120+640=40+720=$760 for each plan.

What fraction makes the equation true? Enter the answer in the boxes. 5/6x =20/24

Darina [25.2K]

Answer:

x=1

Answer:

Thus both answers are: Positive infinity

Step-by-step explanation:

The Absolute Value

It's the positive magnitude of a number, regardless of its sign, or zero if the number is zero.

Some examples of absolute values are:

$\mid 4 \mid =4$

$\mid -4 \mid =4$

$\mid 0 \mid =0$

$\mid -107.5 \mid =107.5$

We have the function:

$g(x)=4\mid x-2\mid -3$

As x approaches negative infinity, the absolute value approaches positive infinity, and the whole expression approaches positive infinity.

As x approaches positive infinity, the absolute value approaches positive infinity, and the whole expression approaches positive infinity.

Thus both answers are: Positive infinity

Evaluate each of the following to three significant figures, and express each answer in SI units using an appropriate prefix: (a

Softa [21]

Answer:

a). $4.86\times 10^{-15}$ m

b). $4.21\times 10^{-2}$ m³

c). $7.00\times 10^{3}$ N²

Step-by-step explanation:

In this question we have to convert each option into SI units.

a). $4.86(10^{-6})^{2}$ mm

= $4.86\times (10^{-12})\times (10^{-3} )$ m

= $4.86\times 10^{-15}$ m

b). (348 mm)³

= $(348)^{3}\times (10^{-3})^{3}$ m³

= $42144192\times 10^{-9}$ m³

= $4.21\times 10^{-2}$ m³

c). $(83700)^{2}\times (10^{-3})^{2}$ N²

= $700569\times 10^{4}\times 10^{-6}$ N²

= $7.00\times 10^{9}\times 10^{-6}N^{2}$

= $7.00\times 10^{3}$ N²
