explain ehy the square root of 64 has a positive and a negative value.

Answers

Answer 1
The square root of 64 is 8, or -8

This is because 8 times 8 is 64

And -8 times -8 is 64 (because a negative times a negative is a positive)
Answer 2
The square root of 64 has both a negative and positive value because as we know it's 8 and -8. To square, you simply multiply the number by its self twice, since a negative number time a negative number is a positive number and a positive number times a positive number is also positive so -8x-8=64 and 8x8=64.

What are some rules of exponents?

Some common rules of exponents are

a^b/a^c = a^(b - c),

a^b.a^c = a^(b + c).

We can only add and subtract exponents only when we have the same base.

Given, (6.47×10⁻¹⁵)/(3.36×10⁻²⁹).

Here we have base 10 raised to some power.

So,  (6.47×10⁻¹⁵)/(3.36×10⁻²⁹).

=  (6.47×10⁻¹⁵⁻⁽⁻²⁹⁾)/(3.36).

=  (6.47×10⁻¹⁵⁺²⁹⁾)/(3.36).

= (6.47×10¹⁴)/(3.36).

So, the last calculator correctly shows (6.47×10⁻¹⁵)/(3.36×10⁻²⁹).

Letters a, b, c, and d are angle measures. Which should equal 105° to prove that f ∥ g?

Answers

The Answer is Option D, which is d.

If f is parallel to g, then c should equal 75 degrees because c and 75 degrees are vertical angles. If C is 75 degrees then D must equal 105 degrees because c and d are both on the left side of line f which means they must add up to 180 degrees, which should get you to this equation: c + d = 180. We can replace c for 75 because we already known that, which should get you: 75 + d = 180. So you should then subtract 75 against 180 to get your answer: d = 105.


Hope this helps, Have a good day!


A Brainliest would be nice.

Final answer:

The question likely pertains to the geometry principle of parallel lines and transversals. To determine which angle would need to measure 105° for line f to be parallel to line g, we'd need more context or a diagram. Typically, congruent corresponding or alternate angles would indicate parallel lines.

Explanation:

This question appears to be related to parallel lines and transversals in geometry. However, without a clear diagram or proper context, it's hard to definitively state which angle should be 105° to prove that f is parallel to g. Typically, corresponding angles, alternate interior angles, or alternate exterior angles are congruent (equal) when two lines are parallel and cut by a transversal. For instance, if 'a' and 'b' form corresponding angles with the transversal, and angle 'a' is given as 105°, then angle 'b' would also be 105° for the lines to be parallel. This corresponds to the angle properties of parallel lines.

twenty-five is the quotient of a number y and 3.5 (write as algebraic expression)

Answers

The algebraic expression that represents the statement 'twenty-five is the quotient of a number y and 3.5' is written as (y / 3.5) = 25.

An explanation of an algebraic expression representing the quotient of a number y and 3.5.

The student is asking to express the statement "twenty-five is the quotient of a number y and 3.5" as an algebraic expression. In algebraic terms, the quotient of y divided by 3.5 is represented by[tex](\frac{y}{3.5})[/tex]or (y / 3.5).

Therefore, the complete algebraic expression that represents this statement is (y / 3.5) = 25.

The algebraic expression for 'twenty-five is the quotient of a number y and 3.5' is 25 = y / 3.5. To find y, you multiply 25 by 3.5.

The algebraic expression that represents the statement 'twenty-five is the quotient of a number y and 3.5' is written as 25 = y / 3.5.

To solve for y, you would multiply both sides of the equation by 3.5 to isolate y. This would give you: y = 25 x 3.5.

a package of 5 pairs of insulated socks costs $41.45. What is the unit price..... how would I do the math

Answers

You would divide 41.45 by 5 and the answer would be 8.29

Final answer:

The unit price for the insulated socks is found by dividing the total cost of the package, $41.45, by the number of pairs, which is 5. The unit price per pair of insulated socks is $8.29.

Explanation:

To calculate the unit price of the insulated socks, you would divide the total cost of the package by the total number of pairs in the package. Since the package contains 5 pairs and costs $41.45, you would perform the following calculation:

Identify the total cost of the package: $41.45.

Identify the number of pairs in the package: 5 pairs.

Divide the total cost by the number of pairs to find the unit price: $41.45 ÷ 5 = $8.29 per pair.

Therefore, the unit price per pair of insulated socks is $8.29.

General Product Inc. distributed 100 million coupons in 2016. The coupons are redeemable for 30 cents each. General anticipates that 70% of the coupons will be redeemed. The coupons expire on December 31, 2017. There were 45 million coupons redeemed in 2016 and 30 million redeemed in 2017. What was General's coupon promotional expense in 2017?

Answers

Hello,

We want to find out the value of all the coupons redeemed in 2017. If there were 30 million coupons redeemed in 2017 and each coupon is worth 30 cents, we multiply 30 million coupons and 0.30 dollars to get the value of coupons. (We use 0.30 dollars as multiplying by 30 will give us the amount in cents, not dollars)

So, we have:
30,000,000 * 0.30 = 9,000,000

General's coupon promotional expense in 2017 is 9 million dollars.

savannah is painting a striped background for a mural on a wall that is 15 yards long. she wants a total of 96 stripes that’s are all the same width. which calculation should savannah use to decide how wide to make each stripe?

Answers

Answer: D

Final answer:

To determine the width of each stripe, Savannah needs to divide the total length of the wall by the number of stripes she wants.

Explanation:

To determine the width of each stripe, Savannah needs to divide the total length of the wall by the number of stripes she wants. In this case, the wall is 15 yards long and she wants 96 stripes. So, she should use the calculation 15 yards / 96 stripes = 0.15625 yards. Therefore, each stripe should be approximately 0.15625 yards wide.

Factor x2 + 4x + 4! Please help!

Answers

This is a whole squared equation. So, it is (x+2)^2.
If you check it, you get x2 + 4x + 4

Hope this helps!
The answer should be (x + 2)^2 because when factoring using grouping, you can rid of two x's from the first two terms, and you can factor 4 into 2 * 2. Factoring the first two terms rids of the first and leaves two x's in the second. You can check if i'm right by multiplying (x + 2) (x + 2). This should give x^2 + 2x + 2x + 4. Simplyify this into x^2 + 4x + 4 by combining like terms. Hope this helps.

A trick coin is made such that when it is tossed there is a 20% chance of heads landing face up and an 80% chance of tails landing face up. If the coin is tossed twice, what is the probability that the coin will land with heads facing up both times?

Answers

P( heads on one toss) = 0.20

P  ( 2 heads)  = 0.20 * 0.20  = 0.04   or 4%

Answer:  4 %

Step-by-step explanation:

According to the question,

20% chance of heads landing face up

Therefore, probability of getting a head, [tex]P(H) = \frac{20}{100} = \frac{1}{5}[/tex]

The probability of getting tail, [tex]P(T) = \frac{80}{100} = \frac{4}{5}[/tex]

Thus, the  probability that the coin will land with heads facing up both times

= [tex]\frac{1}{5}\times \frac{1}{5}[/tex]

=   [tex]\frac{1}{25}[/tex]

=   0.04 or 4 %

Thus the required probability is 4 %.
