Answer : 52 boys : 26 girls
Step - by - step explanation :
Now we can guess, whatever number we put HAS to be 26 more boys than girls and it has to follow the 2 boys : 1 girl ratio . . .
26 boys : 13 girls <-- this follows the 2:1 ratio but is NOT 26 more boys than girls
52 boys : 26 girls <-- this follows the 2:1 ratio and has 26 more boys than girls ! :D
A Hospital telephone operator has observed that calls arrive at a rate of 300 calls per hour. What is the probability that there are exactly 5 calls in 10 minutes?
Answer:
It can be done using poisson distribution.
λ = 30 calls/hr = 1.5 calls/3min
Now P(X=x)=e−λ.λxx!
So P(X=0)=e−1.5

The proportional relationship between the number of songs Stella downloads,
s, and the total cost in dollars and cents, c, can be represented by the equation
c=1.17s. How much does it cost to download a single song?
Answer:
1.17 dollars!
Step-by-step explanation:
We are given the equation c=1.17s
To break it down, it means that the cost in dollars=1.17 times amount of songs.
Lets plug in 1 for s.
1.17*1=1.17!
For one song, it will cost 1.17 dollars !

Answer: 55% of 180, 12% of 700, and 30% of 260.
Step-by-step explanation:
55% of 180 = 99…
30% of 260 = 78…
and 12% 700 = 84…
Answer:
55% of 180 > 12% of 700 > 30% of 260
Step-by-step explanation:
55% of 180 = 99
30% of 260 = 78
12% of 700 = 84

Answer:
-s-6>-7
Step-by-step explanation:
Just ask!
Hope this helps. :)
Answer:
-s-6>-7 (top right)
Step-by-step explanation:
s = -18 > means what is on the left is bigger than what is on the right
top right one = - s - 6 > - 7
top right one = - ( - 18) - 6 > -7
top right one = 18 - 6 > -7
top right one = 12 is bigger than -7

Question 47 of 55
Expression A: 3(x + 1)
Expression B: 3x+3
Which statement does not show that these expressions are equivalent?
A. Both expressions involve addition
B. The expressions name the same number regardless of the value
of x
C. 3(x+ 1) can be rewritten as 3x+ 3 using the distributive property.
D. Substituting any value of x makes the expressions equivalent.
SUBMIT
Answer:
D
Step-by-step explanation:
Substituting any value of x does not make the expressions equivalent. Replacing x for any two different values would equate to different unequal values.
Answer the questions below to find the total surface area of the can. (55 points, help fast)
Answer:
Hope this helps
Step-by-step explanation:
first question --> area of circle ---> [tex]\pi r^{2}[/tex] ---> [tex]1.5^{2} \pi[/tex] ---> [tex]2.25\pi[/tex]
second question --> unclear quetion but I assume 4?
third question --> area of cylinder --> [tex]r^{2} \pi h[/tex] --> [tex]2.25\pi h[/tex] --> [tex]2.25\pi 4[/tex] --> [tex]9\pi[/tex]
h --> height
r --> Radius
[tex]\pi[/tex] --> pi
The total surface area of the can is 61.23 square inches
How to calculate the total surface area of a canThe formula for calculating the total surface area of a can is expressed as:
S = 2πr(r+h)
where:
h is the height
r is the radius
Given the following parameters
h = 5in
r = 1.5in
S = 2(3.14)(1.5)(1.5 + 5)
S = 6.28(1.5)(6.5)
S = 61.23 square inches
Hence the total surface area of the can is 61.23 square inches

A zookeeper is monitoring the population of gazelles. The herd needs to have exactly three times more males than females to thrive. The zoo only has room for a maximum of 12 female gazelles. Let x represent the number of female gazelles and y represent the number of male gazelles. Write the constraints that represent the possible number of male and female gazelles that can live in a thriving population at the zoo. X > 0 and y > 0 0 < x ≤ 12 and 0 < y ≤ 36 0 < x ≤ 12 and y > 36 x > 0 and y < 23.
Option C is correct.
Given to us:
female gazelles[tex](x)[/tex] can be maximum of 12 only. therefore,
Condition 1 is [tex]12\geq x>0[/tex].
while,
male gazelles[tex](y)[/tex] should be exactly 3 times more than females to thrive. therefore,
Condition 2 is [tex]36\geq y>0[/tex].
There is only one option among all the options available which is satisfying both the conditions. therefore, option C is the correct option.

John solved the inequality 3x – 5 ≥ 28 and determined that x could equal 12. Is John correct? Explain why or why not.
Answer:
John is correct
Step-by-step explanation:
Let's solve the inequality:
[tex]3x-5\geq28[/tex]
[tex]3x\geq33[/tex]
[tex]x\geq11[/tex]
As we can see, the value of x can be either 11 or anything greater than 11. Since 12 is included in that solution set, John is correct.

15.) Vincent pays $202 in advance on his account at the health spa. Each
time he uses the spa, $6 is deducted from the account. Write an equation
that represents the value remaining in his account after x visits to the spa.
Find the value remaining in the account after 18 visits. *
O V = 6 - 202x; $94
O V = 6 - 202x; $1,216
O V = 202 - 6x; $94
O V = 202 - 6x; $1,230
Answer:
O V=202-6x; $94
Step-by-step explanation:
202 needs to be placed before the 6, eliminating options 1 and 2. It can't be option 4 because thats more than 202, leaving us with option 3. Check you answer by replacing x with 18. O V=202-6(18) ->O V=202-108 -> 202-108=$94.

24 inches of red ribbon. The ribbon costs
$2.00 per foot. What is the total cost of
the ribbon?
Answer:
It would've costed $8 to buy these ribbons.
Step-by-step explanation:
Given:
3 feet of blue ribbon = 36 inches of blue ribbons2 feet of red ribbon = 24 inches of red ribbons\1 foot of ribbon = $2(3 + 2) x 2 = Total cost
=> (5) x 2
= $10
Therefore, it would've costed $10 to buy these ribbons.
