Tom sells baseball cards at 10 for 35 cents. Is that better deal than 12 for 40 cents? Prove your thinking
Answer:
12 for 40 cents is a better deal.
Step-by-step explanation: 35divided by 10 is 3.5 and 12 divided by 40 is 3.333... therefore for just one card it is cheaper but you are getting more cards anyways.
Determine whether 33 divides the product of 2⋅3⋅7⋅11. If it does divide the product, find the quotient. If it does not divide the product, indicate the smallest factor that should be included in the product to make it divisible by 33. Please explain
Answer:
The answer would be 30
Step-by-step explanation
For positive integers: 2 ⋅ 3 ⋅ 5 ⋅ 7 ⋅ 11 = 2310 For all integers: ± ( 2 ⋅ 3 ⋅ 5 ) = ± 30 For Gaussian integers: ± 1 ± 3 i and ± 3 ± i (all combinations of signs) Explanation: A prime number is a number whose only factors are itself, units and unit multiples of itself. So in the positive integers, the first few primes are: 2 , 3 , 5 , 7 , 11 , ... So the smallest composite positive integer with the five smallest prime positive integers as factors is: 2 ⋅ 3 ⋅ 5 ⋅ 7 ⋅ 11 = 2310 If we extend our interest to include negative integers, then the smallest primes are: 2 , − 2 , 3 , − 3 , 5 , − 5 , ... So the smallest composite integers with the five smallest prime integers as factors are: ± ( 2 ⋅ 3 ⋅ 5 ) = ± 30 If we consider Gaussian integers, then the smallest primes are: 1 + i , 1 − i , − 1 + i , − 1 − i , 1 + 2 i , 1 − 2 i , − 1 + 2 i , − 1 − 2 i , 2 + i , 2 − i , − 2 + i , − 2 − i , 3 , − 3 ,... So the smallest composite Gaussian integers with the five smallest prime Gaussian integers as factor are: ( 1 + i ) ( 1 + 2 i ) = − 1 + 3 i , 1 + 3 i , − 1 − 3 i , − 1 + 3 i , 3 + i , 3 − i , − 3 + i , − 3 − i

A circle has its center at (-4,8), and just touches the y-axis
Answer:i'm a bit confused
Step-by-step explanation:
are you asking a question or not?
Answer:
r = 4 units
Step-by-step explanation:
From the question it is not clear that what you want to ask. But as per me you are interested in finding the radius of the circle.
Since, circle is touching y-axis at has a center (-4, 8) so it's radius will be equal to the x-coordinate.
Here, x - coordinate is - 4
Since radius is a non negative number.
So, r = 4 units
What is the domain of the square root function graphed below?
Answer:
[tex]x \geqslant - 4[/tex]
Step-by-step explanation:
Domain is the set of x-values. We look at the graph and look for the start of x-value.
The start of domain begins at x = -4 and has no ending (positive infinity.)
Thus, our answer is x >= -4

In a certain breed of cattle, the length of gestation has a mean of 284 days and a standard deviation of 5.5 days. Thirty-four percent of gestation periods are longer than how many days, rounded to the nearest whole number?
Answer:
286
Step-by-step explanation:
Given :
Mean (m) = 284
Standard deviation (s) = 5.5
P(Z > x) = 0.34
According to the standardized formula :
Zscore = (x - m) / s
Uaing the Z probability calculator ; The Z value at P(Z > x) = 0.34 is 0.412
Hence, Zscore = 0.412
Zscore = (x - m) / s
0.412 = (x - 284) / 5.5
5.5 * 0.412 = x - 284
2.266 = x - 284
x = 2.266 + 284
x = 286.266
x = 286 (nearest whole number)
I WILL GIVE BRAINLIEST Justin is trying to find a new cell phone plan and was deciding between Verizon and AT&T. The following graph shows the rates of the phones over a period of time:
If Justin is only looking for a plan for 2 years, which is a better plan?
If Justin is looking for a plan for 7 years, which is a better plan?
What happens at point A?
Answer:
1. AT&T would be best for 2 year plan
2. Verizon would be best for 7 year plan
3. Point A is where both intersects showing the the time where both are at the same price. It also shows that after that point, is where verizon would be a better pick
Step-by-step explanation:
At&T is best for 2 year plan because for 2 years, it is less then $160 which is how much the Verizon plan costs for 2 year looking at the graph.
Verizon is best for 7 year as at the 6th year, AT&T is much more higher than Verizon meaning that if both lines keeps going on, Verizon will be cheaper for the long term
Even though Verizon may be expensive at first, after the point A, it shows that Verizon would be a better choice if you are going to use it for 3+ years.

The observations X1, . . . , Xn have a mean of 52, a median of 52.1, and a standard deviation of 7. Eight percent of the observations are greater than 66; 7.9% of the observations are below 38. Based on this information, which of the following statements best describes the data?
a. The distribution has positive skew.
b. The distribution has negative skew.
c. The distribution has high kurtosis.
d. The distribution conforms to a normal distribution.
Answer:
d. The distribution conforms to a normal distribution.
Step-by-step explanation:
A normal distribution is when data has equal symmetry such that the distribution is not positive skewed nor negative skewed. A normal distribution has zero skewness as mean, median and mode are all equal.
In the above example, the data has a normal distribution because most values lie close to the mean(7.9 percent are less than 38 and 8 percent are more than 66)

What is greater 6ft or 300cm
I think it; 300cm is greater.
Why; 300 cm make 9 ft.
9 ft > 6 ft
300cm is greater than 6 ft.
What is unit conversion?Unit conversion is a multi-step procedure that includes rounding, selecting the appropriate number of significant digits, and multiplying or dividing by a numerical factor.
For this problem, we need to do a unit conversion between ft and cm. since,
1 ft = 30.48 cm
6 ft = 182.88 cm.
Therefore 300cm is greater than 6 ft.

¿Cuánto pagaré por una falda que costaba 25 euros si me cargan un IVA del 21%?
porfa es para un trabajo de mate que tengo que entregar mañana
Answer:
Pagarás 30.25 euros por la falda
Step-by-step explanation:
Porcentajes
Si necesitamos agregar un porcentaje a una cantidad conocida podemos hacerlos de dos formas: Calculamos el monto del aumento y se lo sumamos a la cantidad original, o también calculamos el porcentaje aumentado y lo aplicamos a la cantidad original. Lo haremos de las dos formas:
La falda costaba 25 euros y se le cargará un 21% de IVA.
El aumento sería:
25*21/100=5.25 euros
El precio final es
25+5.25=30.25 euros
De la segunda forma. El costo original era el 100%, con el 21% de aumento sería 121%. Aplicamos el 121% al precio original para obtener:
25*121/100=30.25 euros
Se obtiene el mismo resultado: Pagarás 30.25 euros por la falda
find value of x supplementary pair
Answer:
x=70
Step-by-step explanation:
Because the pair is a supplement, it should add up to 180°, so that means that (2x+6)+34=180
Answer:
[tex]x=70[/tex]°
Step-by-step explanation:
Supplementary angles are a pair of angles that form a linear pair, or a straight angle/line, and their measure sum to [tex]180[/tex]°. We are given a pair of supplementary angles with measures of [tex](2x+6)[/tex]° and [tex]34[/tex]°. Therefore, all we have to do to find the value of [tex]x[/tex] is set the sum of the given angles' measures to [tex]180[/tex]°. In an equation, that would be:
[tex]2x+6+34=180[/tex]
Solving for [tex]x[/tex], we get:
[tex]2x+6+34=180[/tex]
[tex]2x+40=180[/tex] (Simplify LHS by combining like terms)
[tex]2x+40-40=180-40[/tex] (Subtract [tex]40[/tex] from both sides of the equation to isolate [tex]x[/tex])
[tex]2x=140[/tex] (Simplify)
[tex]\frac{2x}{2} =\frac{140}{2}[/tex] (Divide both sides of the equation by [tex]2[/tex] to get rid of [tex]x[/tex]'s coefficient)
[tex]x=70[/tex]° (Simplify)

Answer:
y = ½x
_____
k = ½
Step-by-step explanation:
[# of donuts] 2 → [total price] $1
[# of donuts] 12 → [total price] $6
[# of donuts] 3 → [total price] $1.50
[# of donuts] 7 → [total price] $3.50
Because price is the dependent variable, it is the y value. And since the price is the y variable, the donuts must be the x value.
Because the price is ½ the # of donuts, y is ½ x which means y = ½x and k = ½.

Buffalo Bill currently weighs 202 lb. He wants to weigh 180 lbs for his reunion which is 35 days from today. How many pounds per week must he lose?
Answer:
He must lose 4.4 pounds per week.
Step-by-step explanation:
Buffalo Bill currently weighs 202 lb. He wants to weigh 180 lbs for his reunion.
This means that he needs to lose 202 - 180 = 22 lb.
35 days from today.
Each week has 7 days. So this is 35/7 = 5 weeks from now.
How many pounds per week must he lose?
22 pounds in 5 weeks, that is 22/5 = 4.4 pounds per week.
