Divide 7 by 8:
7/8
(8 goes into 7 zero times, add decimal point and 0, 8 goes into 70 eight times, add 6 and another zero, 8 goes into 60 seven times, add 4 and another 0, 8 goes into 40 five times)

Bethany wants to estimate the value of (4.296 times 10 Superscript 11) (1.8614 times 10 Superscript negative 14). Which statemen
avanturin [10]

Answer:

D. The number will be less than 1 because when adding the exponents,

11 + (-14) = -3, and a number in scientific notation with a negative exponent is less than 1.

Step-by-step explanation:

The question lacks appropriate option. Find the options below;

A. The value will be greater than 1 because 4.296 x 10^11 is a very large number and multiplication always increases the size of a number.

B. The value will be greater than 1 because 4 x 2 = 8 and 8 is larger than 1.

C. The value will be less than 1 because (4.296 x 10^11) x (1.8614 x 10^-14) will be a negative number. All negative numbers are less than one.

D. The number will be less than 1 because when adding the exponents,

11 + (-14) = 3, and a number in scientific notation with a negative exponent is less than 1.

Given the expression (4.296*10^{11})(1.8614*10^{-14}), to expand the expression we will apply some of the law of indices below. If a, b and m are integers

a^m*a^n = a^{a+m}

= (4.296*10^{11})(1.8614*10^{-14})\\\\= (4.296*1.8614)(10^{11}*10^{-14}) \\\\= 7.9965744 * 10^{11}*10^{-14}\\sum \ up \ the\  power\ of\ the \ exponents\\\\=  7.9965744 *10^{11-14}\\\\= 7.9965744 *10^{-3}\\

= 0.0079965744

<em>Based on the result, it can be seen that the resulting value is less than 1 due to the negative power of its exponent (i.e -3). Any scientific notation having a negative exponent always returns a value that is less than 1.</em>

D. 25 <br> Math question please help
Wewaii [24]
Alright this one is really simple even though it looks like alot. Start by looking at what they give you.

LM=9, LM is congruent to SP so SP=9

Now NR=16 and both NP and PR are congruent to MS.

16÷2=8
NP and PR = 8, So, MS=8

SR=8, MP is congruent to SR so MP=8

Alright so what we've just found out is that SP=9, MS=8, MP=8

We have three the line segments that make up SMP now! Just add them together to get your answer.
9+8+8= 25
Answer = D. 25

The drawing is composed of a rectangle and a semicircle find the area of the figure to the nearest unit.
zimovet [89]
The area equation for a rectangle is length times width.  And the area equation for a half (or semi) circle is (1/2) times pi (or 3.14) times the radius squared.

So, you have to add the area of the rectangle and semi-circle together.

Rectangle: A = 18*10 = 180 cm^2
Semi-circle: A = (1/2)*3.14*(18/2)^2 = 127.17 cm^2

Add those together to get 307.17cm^2 or choice C.
