Step-by-step explanation:
it takes 30 kids 6 hours to build a man sized Sand Castle. how many kids were there if the same game took only two-and-a-half hours
Answer:
There were 72 kids there.
Step-by-step explanation:
This question can be solved using proportions, by a rule of three.
The number of kids and time are inversely proportional, that is, if we increase the number of kids to build the castle, the time it takes will decrease. This means that to solve the rule of three, instead of applying cross multiplication, we apply line multiplication.
We have that:
30 kids - 6 hours
x kids - 2.5 hours.
Applying line multiplication
[tex]2.5x = 30*6[/tex]
[tex]x = \frac{180}{2.5}[/tex]
[tex]x = 72[/tex]
There were 72 kids there.

Answer:
Prime number: A prime number has factor of only 1 and itself.
Ex: 3: 1 and 3 are the only ways to compose 3.
A whole number that has factors other than 1 and itself is called a composite number.
Ex: 8: the factors of 8 include 1,2,4,8
Circle 5,7,2,19,3,11
Box 18,20,22,16,15,30,26,38,45,10,21,6,14

Researchers interviewed street prostitutes in Canada and the United States. The mean age of the 100 Canadian prostitutes upon entering prostitution was 19 with a standard deviation of seven. The mean age of the 130 United States prostitutes upon entering prostitution was 21 with a standard deviation of nine. Is the mean age of entering prostitution in Canada lower than the mean age in the United States
Answer:
Step-by-step explanation:
The null and the alternative hypothesis is:
[tex]H_o: \mu_c \ge \mu_{us}[/tex]
[tex]H_a : \mu_c < \mu_{us}[/tex]
The t- student test statistics can be computed as:
[tex]t = \dfrac{x_c- x_{us}}{\sqrt{\dfrac{\sigma_c^2}{n_c} + \dfrac{\sigma_{us}^2}{n_{us}} }}[/tex]
[tex]t = \dfrac{19- 21}{\sqrt{\dfrac{7^2}{100} + \dfrac{8^2}{130} }}[/tex]
t = -2.017
degree of freedom = (n₁ - 1) + (n₂ - 1)
= (100 - 1) + (130 - 1)
= 228
Using the data of t-value and degree of freedom;
The P-value = -0.224
Decision rule: Do not reject the null hypothesis if the p-value is greater than ∝(0.01)
Conclusion: We reject the null hypothesis since the p-value is less than ∝.
Therefore, there is enough evidence to conclude that the mean age of entering prostitution in Canada is lower than that of the United States.

h(t)=(49+4.9t)(10-t) solve for t
Answer:
t = ±10
Step-by-step explanation:
after using the FOIL method you have the following:
490 + 49t - 49t - 4.9t²
middle two terms zero out
h(t)= -4.9t² + 490
if you multiply by -10 you can get perfect squares
h(t) = 49t² - 4900 which has two factors: (7t + 70)(7t - 70)
now set each factor equal to zero and solve:
7t + 70 = 0
7t = -70
t = -10
7t - 70 = 0
7t = 70
t = 10
HELP ME PLZ!!!! A bakery sold 48 chocolate cupcakes in a day, which was 12% of the total number of cupcakes sold that day. How many total cupcakes did the bakery sell that day?
400 cupcakes will be sold by the bakery on that day if the percentage of total sales is 12%.
What is the percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
A set of financial statements with a budgeted amount are created using the percentage-of-sales approach. The predicted sales level for the budget period is calculated by converting each historical cost into a percentage of net sales.
It is given that,
Total number of chocolate cupcakes sold = 48
Let the x be the cupcakes that will be sold by the bakery on that day
According to the given condition, 12% of the total number of cupcakes is 48.
⇒12% of x = 48
⇒(12/100) × x =48
⇒x=(48×100)/12
⇒x=400
Thus, 400 cupcakes will be sold by the bakery on that day if the percentage of total sales is 12%.

How were some European Jews able to come to Georgia in the 1930s? Check all that apply.
The US government loosened its restrictions on Jewish immigration.
Officials in the Georgia state government sponsored most immigrants.
Jewish immigrants tried to help family members back in Europe escape.
Private organizations helped Jewish children and teenagers find homes.
American citizens legally agreed to be responsible for Jewish immigrants.
Jewish American activists worked to bring immigrants to the United States.
Answer:
Georgian Jews (Georgian: ქართველი ებრაელები, romanized: kartveli ebraelebi) are a community of Jews who migrated to Georgia during the Babylonian captivity in 6th century BC.[2] It is one of the oldest communities in that land.
Prior to Georgia's annexation by Russia in 1801, the 2,600-year history of the Georgian Jews was marked by an almost total absence of antisemitism and a visible assimilation in the Georgian language and culture.[3] The Georgian Jews were considered ethnically and culturally distinct from neighboring Mountain Jews.[4] They were also traditionally a highly separate group from the Ashkenazi Jews in Georgia, who arrived following the Russian annexation of Georgia.
As a result of a major emigration wave in the 1990s, the vast majority of Georgian Jews now live in Israel, with the world's largest community living in the city of Ashdod.The Georgian Jews traditionally lived separately, not only from the surrounding Georgian people, but also from the Ashkenazi Jews in Tbilisi, who had different practices and language.
The community, which numbered about 80,000 as recently as the 1970s, has largely emigrated to Israel, the United States, the Russian Federation and Belgium (in Antwerp). As of 2004, only about 13,000 Georgian Jews remained in Georgia. According to the 2002 First General National Census of Georgia, there are 3,541 Jewish believers in the country.[5] For example, the Lezgishvili branch of Georgian Jews have families in Israel, Moscow, Baku, Düsseldorf, and Cleveland, Ohio (US). Several hundred Georgian Jewish families live in the New York tri-state area, particularly in New York City and Long Island.

Answer:
x = 8 or x = -24
Step-by-step explanation:
Hello!
An absolute value expression has two cases, a positive and a negative.
Therefore, we have to solve two equations here:
x + 8 = 16x + 8 = -161) x + 8 = 16x = 82)x + 8 = -16x = -24The two solutions are x = 8 and x = -24.

Estelle has 6 liters of juice. If she pours 0.25 liters into each glass, how many glasses of juice will she make?
Answer:
24 glasses
Step-by-step explanation:
We are given that
Estelle has juice=6 liters
She pours juice in one glass=0.25 L
We have to find the number of glasses of juice made by her.
Using unitary method
0.25 L juice pour in 1 glass
1 L juice pour in 1/0.25 glasses
6 liters juice pour in glasses=[tex]\frac{1}{0.25}\times 6[/tex]
6 liters juice pour in 24 glasses
Hence, she will make 24 glasses of juice.
