Taylor Whitney it's a word problem A payday loan company charges a $25 fee for a $700 payday loan that will be repaid in 12 days

Aleonysh [2.5K]

Answer:

Step-by-step explanation:

Using I = (PRt)/100

Ratio of fee and principal amount = fee/amount

= 25/700

= 1/28

Fee(interest) for 12 days = $25

In 1 day,

= (1/28) * 1/12

= 1/336

For a year, that is 365 days

Fee (interest) = 365 * (1/336)

= 1.08 * 100

= 108 %

Step-by-step explanation:

Determining the length of BC

From the diagram, it is clear that

The point B is located at (-8, 10) and point C is located at (8, 10)

Since points A and C are located on a horizontal straight line. Thus, the length of BC can be determined by counting the x-axis units from reaching x = -8 to x = 8. i.e. 8-(-8) = 8+8 = 16

Thus, the length of BC = 16 units

Determining the length of CD

Given

C (8, 10)

D (2, -2)

The distance between C(8, 10) and D(2, -2)

$\mathrm{Compute\:the\:distance\:between\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}$

$CD=\sqrt{\left(2-8\right)^2+\left(-2-10\right)^2}$

$=\sqrt{6^2+12^2}$

$=\sqrt{36+144}$

$=\sqrt{180}$

$=\sqrt{36\times 5}$

$=6\sqrt{5}$

Thus, the length of CD $=6\sqrt{5}$ units

Determining the length of ED

Given

E (-8, -4)

D (2, -2)

The distance between E(-8, -4) and D(2, -2)

$ED=\sqrt{\left(2-\left(-8\right)\right)^2+\left(-2-\left(-4\right)\right)^2}$

$=\sqrt{10^2+2^2}$

$=\sqrt{100+4}$

$=\sqrt{104}$

$=\sqrt{26\times \:4}$

$=2\sqrt{26}$

Thus, the length of ED $=2\sqrt{26}$ units

Determining the length of EB

From the diagram, it is clear that

The point E is located at (-8, -4) and the point B is located at (-8, 10)

Since points E and B are located on a vertical straight line. Thus, the length of EB can be determined by counting the y-axis units from reaching y = -4 to y = 10. i.e. 10-(-4) = 10+4 = 14

Thus, the length of EB = 14 units

Can anybody help me with 1 and 2

Anit [1.1K]

1) $x \geq 96$
2) $x\ \textless \ 38$

Here, the variable $x$ can assume any value, and usually an inequality presented like this has $x$ as a stand-in for all real numbers. If we really wanted to make that fact clear, we could write the two inequalities like this:

$x \geq 96, x\in\mathbb{R}\\ x\ \textless \ 38, x\in\mathbb{R}$

Formally, you'd read $x\in\mathbb{R}$ as " $x$ is an element of the set of real numbers," which is a fancy way of saying that $x$ can be any real number.
