Answer 1

Answer:

Answer:

$a.\ -3\nb.\ 6\nc.\ -5\nd.\ 4$

Step-by-step explanation:

First, it is important to remember which are the Negative numbers and the Positive numbers.

The Positive numbers are defined as all those numbers that are greater than zero and the Negative numbers are defined as all those numbers that are less than zero.

Then:

a. "3 degrees below $0\°F$ " indicates that the temperature is actually $-3\°F$ , which is less than zero. Then, it is a negative number:

$-3$

b. Let be 0 represents the sea level, "6 feet above the see level" indicates that the number is positive:

$6$

c. "Lost 5 pounds" indicates that now the actual weight is 5 pounds less than the original, which indicates that it must be expressed as a negative number:

$-5$

d. "Found $\$4$ " means that now the actual amount of money is greater than it was before. Then, the number that represents this is a positive number:

$4$

Mary bought a paid of jeans and a sweater.The pair of jeans costs $30 and the sweater costs $35 .If sales tax is 6% ,how much did Toby spend in total for the jeans and sweater? Explain please

Answers

$30 + $35 = $65

Assuming tax is on whole sale not each item:
$65 * 0.06 (6%) = $3.90 (6% of $65)

$65 + $3.90 = $68.90 ($65 + 6%)

OR

You could combine both of these steps and just use this working:
$65 * 1.06 (106%) = $68.90 (106% of $65)

A bag contains 5 black marbles and 4 white marbles. A spinner has 3 equal sections labeled 1 through 3. What is the probability of drawing a black marble from the bag and spinning a 1 on the spinner?

Answers

$5+4=9 \leftarrow \text{marbles in total}$

$\text{The probability of drawing a black marble is } (5)/(9)$

$\text{The probability of spinning a 1 is } (1)/(3)$

$\text{The probability of both is } (5)/(9)\cdot(1)/(3)=(5)/(27)$

The ratios a:b and b:c are equivalent to one anotherSelect all the statements that must be true

1. a=c

2. $(b)/(a) = (c)/(b)$

3. b-a=c-b

4. a
5. if a=b, then b=c

I think #2 is correct ,but I don't know about the others

Answers

Options 2 and 5 i.e., $(b)/(a)=(c)/(b)$ and $b=c$ are the correct statements such that $(a)/(b)=(b)/(c)$ .

Ratio

Ratio is the mathematical indication that tells how many times one number contains another.

How to simplify the ratios?

Reciprocate the given proportion both sides-

$(b)/(a)=(c)/(b)$

So, option 2 is correct.

Now, if $a=b$ then, the proportion will become-

$1=(b)/(c)\nb=c$

So, option 5 is correct.

Thus, options 2 and 5 are the correct statements.

#SPJ2

a : b
b : c

Imagine if the ratio is as follows :
3 : 6
6 : 12

Yes, only number 2 is correct.

Your number 4 seems to only consist of a. Hence, I can't make any assumptions based on that.

So yes, only number 2 is correct.
