Which has the greatest value -10, -3, 6, 9

Peter decided that the total cost for a $24.55 pair of jeans and a $12.25 shirt was $26.80 was Peter answer reasonable? Explain

zhuklara [117]

No because

24.55
+ 12.25

1
24.50
+ 12.20

24.00
+ 12.00
.80

20.00
+ 10.00
6.80

The answer is 36.80 so he was 10.00 off.

Lily has $2. 75 in her pocket, consisting of dimes and quarters. If there are 17 coins in all, how many of each does she have?.

Nikitich [7]

Answer:

Lily has 7 Quarters and 10 Dimes

Step-by-step explanation:

Let's use pennies instead of $.

Let D and Q stand for the numbers of Dimes and Quarters, respectively.

We are told that there are 17 coins total:

D + Q = 17

We also learn that they amount to 275 (pennies). We can write that as:

10D + 25Q = 275 [Each D is worth 10 pennies, etc.]

We have two equations and two unknowns. We can rearrange one equation to find the value of either of the unknowns, and then use that it the second equation.

I'll rearrange the first:

D + Q = 17

D = 17 - Q

Now use this value of D in the second equation:

10D + 25Q = 275

10(17-Q) + 25Q = 275

170 - 10Q + 25 Q = 275

15Q = 105

Q = 7 : 7 Quarters.

Since D + Q = 17:

D + 7 = 17

D = 10 Dimes

==========================================

Let's check these results:

Q = 7 Quarters

D = 10 Dimes

1. Is this 17 coins in total? (7+10 = 17) YES

2. Does this add to $2.75? (10*10) + (7*25) = 275 cents?

(100 + 176) = 275 (cents) YES

============================

Lily has 7 Quarters and 10 Dimes

Answer: =6b *The answer should be positive sign.*

Step-by-step explanation:

distributive property: a(b+c)=ab+ac

add numbers.

4+2=6

don't forget to leave with variable.

=6b

Which statement holds true for a skewed histogram showing a distribution of the weights of students in a class?

Vanyuwa [196]

Among the choices, the statement which describes a skewed histogram showing a distribution of the weights of students in a class is:

"The nature of the skew can be verified by the position of the mean with respect to the mode."

The histogram is skewed to the right if the mean is less than the mode and the histogram is skewed to the left if the mean is more than the mode.

Which equation can be used to find B in the triangle below?

WINSTONCH [101]

9514 1404 393

Answer:

(b) tan B = 8/6

Step-by-step explanation:

The mnemonic SOH CAH TOA is intended to remind you of the relevant relationships:

Cos = Adjacent/Hypotenuse

Tan = Opposite/Adjacent

Then angle B is involved in tangent and cosine relationships this way:

tan B = 8/6 . . . . . . matches 2nd choice

cos B = 6/10 . . . . . matches no choices

_____

Additional comment

Both of the offered cosine choices give a cosine value that is greater than 1. The cosine of a real angle is never greater than 1, so those can be rejected immediately.
