A bag contains 22 coins consisting of quarters and nickels. The total value of the coins is $3.90. How many nickels are in the bag? *
Answer:
8 Nickels
Step-by-step explanation:
Since a Nickel is worth 5 cents ($0.05)
And a Quarter is worth 25 ($0.25)
and theres 22 coins
8 of those coins would be nickels which would mean we add 8 nickels up
8 x 0.05 = 0.4
then we add the quarters up
14 x 0.25 = 3.5
3.5 + 0.4 = $3.90
La temperatura mínima en una ciudad el día lunes fue de –2 ºC y la máxima fue de 7 ºC. ¿Cuál fue la variación de temperatura en el día?
Answer:
La variación de temperatura en el día es 9°C.
Step-by-step explanation:
Cuando tenemos dos valores, uno máximo M y uno mínimo m, la variación entre esos valores es la diferencia (la resta) entre el valor máximo M y el valor mínimo m
variación = M - m
En este caso sabemos que la temperatura mínima es -2°C
La temperatura máxima es 7°C
La variación sera entonces:
Variación = 7°C - (-2°C)
Recordar la regla de los signos:
(-)*(-) = (+)
Entonces:
Variación = 7°C - (-2°C) = 7°C + 2°C = 9°C
La variación de temperatura en el día es 9°C.

Which expression is equivalent to the phrase shown below?
The quotient of the sum of 2t and 2, and twice the cube of s
A. 2t +23s2 C. 2t+23s2
B. 2t +22s3 D. 2t+22s3
Answer:
The answer is the letter D
Step-by-step explanation:
The sum of 2t and 2 could be written as:
[tex]a=2t+2[/tex]
Now, the twice of the cube of s will be:
[tex]b=2s^{3}[/tex]
Finally, the quotient between a and b will be:
[tex]\frac{a}{b}=\frac{2t+2}{2s^{3}}[/tex]
Therefore the answer is the letter D

4x^2=27x+40
Solve by factoring
Answer: hewo, there! your answer is below
x= -5/4
or x= 8
Step-by-step explanation:
step 1: Subtract 27x+40 from both sides.
4x2−(27x+40)=27x+40−(27x+40)
4x2−27x−40=0
Step 2: Factor left side of equation.
(4x+5)(x−8)=0
Step 3: Set factors equal to 0.
4x+5=0 or x−8=0
hope this helps you

Point R′ (−2, 8) is the image of point R (−2, 2). Which of the following algebraic representations could be used for that transformation?
Select one:
(x,y)→(−x,y)
(x,y)→(4x,4y)
(x,y)→(x,y+6)
(x,y)→(x+6,y)
Answer:
C) (x,y) → (x,y+6)
Step-by-step explanation:
As the x value stays the same after the transformation, we know that there can be no changes to the value x, automatically limiting the options to answer C.
The mathematical way to find the value y is changed by would be by setting up a small equation as follows:
[tex]8 = 2 + n[/tex], where n is some number that the y value is altered by.
Solving for n gives the value 6, proving that the translation must add 6 to the y value.

8x−2=−11+7x +2
Please help me!!
Answer:
x=-7
Step-by-step explanation:
8x - 2 = -11 + 7x + 2
First, separate the terms: move x to one side
subtract 7x from both sides
8x -7x - 2 = -11 + 7x -7x + 2
x - 2 = -11 + 2
Now get x by itself by adding 2 to both sides
x - 2 +2 = -11 + 2 +2
x = -11 + 4
simplify
x = -7

18. Hoping to lure more shoppers downtown, a city
builds a new public parking garage in the central business
district. The city plans to pay for the structure through
parking fees. During a two-month period (44 weekdays),
daily fees collected averaged $126, with a standard
deviation of $15.
Answer:
The responses to these question can be described as follows:
Step-by-step explanation:
Please find the complete question in the attached file.
For the random condition:
If other regular fees have been chosen at random, I'd claim I'm satisfactory.
State of autonomy:
Truly content, since the 44 daily fees represent less than 10% of the total population of daily payments, the community must have more than 440 daily fees.
In the Normal Condition:
Since the sample size of 44 is 30 or more, the distribution of the sample means is roughly Normal (as per the total probability theorem).

(4 x 104)(2 x 103)
Answer:
85,696
Step-by-step explanation:
4 x 104 = 416
2 x 103 = 203
No sign between parentheses means that you have to multiply the two outcomes of the parentheses.
416 x 203 = 85,696

PLEASE HELP WITH GEOMETRY IM STUCK!?}
Answer:
13.8
Step-by-step explanation:
Recall the trigonometric ratios
Sine = Opposite over Hypotenuse (SOH)
Cosine = Adjacent over Hypotenuse (CAH)
Tangent = Opposite over Adjacent (TOA)
Now lets look back at the question
We are given an angle and its adjacent side length (11) and we need to find the hypotenuse
The hypotenuse and adjacent sides corresponds with the trig function cosine so we will use cosine to solve for x
( remember that cosine = adjacent over hypotenuse )
[tex]cos(37)=\frac{11}{x}[/tex]
step 1 multiply each side by x
[tex]cos(37)*x=xcos(37)\\\frac{11}{x} *x=11[/tex]
now we have [tex]xcos(37)=11[/tex]
step 2 divide each side by cos(37)
[tex]\frac{xcos(37)}{cos(37)} =x\\\frac{11}{cos(37)} =13.77349\\[/tex]
we're left with x = 13.77439
Our last step would be to round to the nearest tenth
We would get that the answer is 13.8
Answer:
G) x = 13.8
Step-by-step explanation:
cos 37° = adj/hyp = 11/x
0.7986x = 11
x = 13.8
