The E indicates scientific notation. The first number is the coefficient of the number in scientific notation. This number is multiplied by a power of 10. The number following the E, which is –8, is the exponent, and the base is 10.

the E-8 at the end means the number is multiplied by 10^-8

so 5.779E-8=

5.779 x 10^-8 =

a negative power means move the decimal place that many places to the left

so 5.779 x 10^-8 =

0.00000005779

Why should we wear rubber gloves on our hands while working with electricity?

natita [175]

Answer:

a simple answer would be that rubber doesnt conduct electricity, so by wearing it you are at a substantially lower risk of being insured by electricity. This is also why people who work with electricity wear rubber soled boots.. to prevent grounding and ultimately, to prevent getting electrocuted. hope this helps :)

The circumference of a circle is 7π m. What is the area of the circle? 3. 5π m² 12. 25π m² 14π m² 49π m².

Juliette [100K]

Area of the circle is the area covered by that circle. The area of the circle whose circumference is 7π m is 12.25π m².

<h3>What is the area of a circle?</h3>

The area of the circle is the area covered by that circle. It is given by the formula,

$\text{Area of the circle}=\pi r^2$

where r is the radius of the circle.

As it is given that the circumference of a circle is 7π m. Therefore, the radius of the circle can be written as,

$\text{Circumference of the circle} = 2\pi r$

$7 \pi = 2 \pi r\\\\r = 3.5\rm\ m$

Now, we know the formula of the area of a circle, therefore, the area of the circle can be written as,

$\text{Area of the circle}=\pi r^2$

$= \pi \times (3.5)^2\\\\= 12.25\pi\rm \ m$

Hence, the area of the circle whose circumference is 7π m is 12.25π m².

Polygon C and polygon D are similar. The perimeter of polygon C is 192 inches, and the perimeter of polygon D is 48 inches. If o

Marianna [84]

Answer:

B. 2 in.

Step-by-step explanation:

First, put the two perimeters together to form a fraction.

192/48, which can simplify to 4/1

Now, following the order in which you put the perimeters (I used C/D,) set it equal to the sides.

$\frac{4}{1} = \frac{8}{x}$

Now, cross multiply. (multiply 1 and 8, 4 and x.)

$4x = 8$

Now, solve.

x=2 inches.

Kylie owes $1,700 on her credit card. The bank charges a monthly interest rate of 0.925%. If Kylie wants to pay off her credit c

aksik [14]

Answer:

$221.44

Step-by-step explanation:

As the bank charges a <em>monthly </em>interest, we cannot calculate a simple or compound interest over the 8 month period. As the balance will decrease each month as Kylie makes payments, the interest applied each month will also decrease. Therefore, we have to use:

<u>Monthly Payment Formula</u>

$\sf PMT=\dfrac{Pi(1+i)^n}{(1+i)^n-1}$

where:

PMT = monthly payment
P = loan amount
i = interest rate per month (in decimal form)
n = term of the loan (in months)

Given:

P = $1,700
i = 0.925% = 0.00925
n = 8 months

Substituting the given values into the formula and solving:

$\implies \sf PMT=\dfrac{1700(0.00925)(1+0.00925)^8}{(1+0.00925)^8-1}=221.4403207$

Therefore, the monthly payment to the nearest dollar will be $221.44
