Shelter A has 500 beds and is 90% occupied. Shelter B is 60% occupied, the ratio of beds in Shelter A to Shelter B is 15:16
Answer:
800 bedsStep-by-step explanation:
Shelter A has 500 beds and is 90% occupied.
Number of occupied beds:
500*0.9 = 450The ratio of beds occupied in Shelter A to Shelter B is 15:16
450/x = 15/16x = 450*16/15x = 480Number of occupied beds in Shelter B is 480 which is 60% of total. Total number of beds is:
480/0.6 = 800Answer:
Answer:there are 900 beds in shelter B
Step-by-step explanation:
Shelter A has a capacity of 300 beds and is 80% occupied. This means that the number of beds in Shelter A that would be
80/100 × 300 = 0.8 × 300 = 240 beds.
Let x represent the capacity of Shelter B. Shelter B is 45% occupied. It means that number of beds in Shelter B that would be occupied is
45/100 × x = 0.45 × x = 0.45x beds.
Total occupancy of shelter A and shelter B would be
240 + 0.45x
The ratio of the occupancy of shelter A to shelter B is 16:27
Total ratio of occupancy = 16 + 27 = 43
Therefore
27/43 × (240 + 0.45x) = 0.45x
27(240 + 0.45x) = 0.45x × 43 = 19.35x
6480 + 12.15x = 19.35x
6480 = 19.35x - 12.15x = 7.2x
x = 6480/7.2 = 900

A national park has two types of bears: Grizzly bears and black bears. A sciantist has reported 9 out of 12 bears she tagged are black bears. Show a model that compares the number of black bears tagged to the number of grizzly bear?
Answer:
Z = 0.75x + 0.25y
Step-by-step explanation:
Two bear types are identified :
Black bears and Grizzly bears
9 out of 12 = black bears ; Hence, 3 are grizzled
For the model:
For a bear population of Number x
Total bear population = black bear, x + grizzled bear, y
Proportion of black bear = 9/ 12 = 0.75
Grizzled bear = 1 - 0.75 = 0.25
Total bear population , Z= 0.75x + 0.25y
Hence,
Z = 0.75x + 0.25y
Carmella simplified the following rational expression. (2x ^ 2 + 7x + 3)/(4x + 12) = ((2x + 1)(x + 3))/(4(x + 3)) = ((2x + 1)(x + 3))/(4(x + 3)) = (2x + 1)/4 After simplifying the expression , she stated that there are no restrictions on x since the denominator of her answer is a constant and cannot possibly equal Did Carmella make any mistakes in her problem ?

De 40 estudiantes de undécimo grado, 14 toman clase de piano y 29 clases se violín.
a. Si cinco estudiantes toman ambas clases,¿ cuántos estudiantes no asisten a ninguna de las dos?
b. ¿cuántos estudiantes toman clase de piano o de violín?
c. cuántos estudiantes toman únicamente clases de violín?
Puedes separar los grupos en:
los que solo toman clases de piano; p
los que solo toman clases de violin: v
los que toman clases de piano y violin; 5
A) para determinar cuántos estudiantes no toman ni piano ni violin, podemos hallar el número total de estudiantes que toman clases solo de piano y los que toman solo de violín y los que toman ambas clases, de la siguiente forma:
Estudian solo piano, p = 14 - 5= 9
Estudian solo violín, v = 29 - 5 = 24
Estudian ambos: 5
Total de estudiantes que toman clases de esos instrumentos : 9 + 24 + 5 = 38
Por tanto, hay 40 - 38 = 2 estudiantes que no toman clases de piano ni violín.
B) ¿cuántos estudiantes toman clases de piano o violín?
Son los que tocan solo piano, o solo violín o ambos y los hallamos arriba: 9 + 24 + 5 = 38.
Respuesta: 38
C) ¿Cuántos estudiantes tocan solo violín?
También lo encontramos arriba: son 29 - 5 = 24
Respuesta: 24
A box is filled with 9 brown cards, 2 yellow cards, and 3 blue cards. A card is chosen at random from the box. What is the probability that it is a brown or a blue
card?
Answer:
9 / 14 for a brown , 3 / 14 for a blue
Step-by-step explanation:
1) summarize all cards 9 (brown) + 2 (yellow) + 3 (blue)= 14 cards.
2) probability depends on how many cards of a particular color, how more cards, then more probability.
3) 9 brown cards, so probability = 9 brown cards to divide all cards 14.

The radius r of the base of a cone is given by the equation r=(3V/piH)
, where V is the volume of the cone and h is the height of the cone. Find the radius of the paper cup to the nearest inch. Use 3.14 for pi .
Answer:
1 inStep-by-step explanation:
Given the expression to calculate the radius r of the base of a cone is given by the equation
r=(3V/piH)
v is the volume = 5in^3
H = 4in
pi = 3.14
Substitute
r = 3(5)/3.14(4)
r = 15/12.56
r = 1.19
r = 1in to the nearest inch
Felipe planted some seeds for a science project. One of his plants grew 6 2/7 inches in the first week, and then it grew 5 11/14 inches during the second week. How much did the plant grow during these two weeks? The answer should be written as a proper mixed number and should be simplified, if possible.
Answer:
The plant grew [tex]12\frac{1}{14}[/tex] inches
Step-by-step explanation:
Operations with Fractions
Felipe planted seeds for a science project. One of the plants grew 6 2/7 inches in the first week and 5 11/14 inches in the second week.
We are required to find the total growth during the two weeks. We have to find the sum of:
[tex]6\frac{2}{7}+5\frac{11}{14}[/tex]
Let's convert both fractions to improper form:
[tex]6\frac{2}{7}+5\frac{11}{14}=6+\frac{2}{7}+5+\frac{11}{14}[/tex]
Adding the integers:
[tex]6\frac{2}{7}+5\frac{11}{14}=11+\frac{2}{7}+\frac{11}{14}[/tex]
Now we find the LCM of 7 and 14 is 14, thus:
[tex]6\frac{2}{7}+5\frac{11}{14}=11+\frac{4}{14}+\frac{11}{14}[/tex]
[tex]6\frac{2}{7}+5\frac{11}{14}=11+\frac{15}{14}=11+\frac{14+1}{14}[/tex]
[tex]6\frac{2}{7}+5\frac{11}{14}=11+1+\frac{1}{14}[/tex]
[tex]6\frac{2}{7}+5\frac{11}{14}=12+\frac{1}{14}[/tex]
Rewriting as a mixed number:
The plant grew [tex]12\frac{1}{14}[/tex] inches

0.4(3.21x+5.6)
Answer:
1.284x + 2.24 is the answer.
Step-by-step explanation:
Simply, all we have to do is distribute the 0.4 to the 3.21x and the 5.6.
(0.4 × 3.21x) + (0.4 × 5.6)
= 1.284x + 2.24
#teamtrees #WAP (Water And Plant)
Answer: = 1.284x + 2.24
explanation: This question is easily solved through the process of distribution.
(0.4 × 3.21x) + (0.4 × 5.6) = 1.284x + 2.24

Answer:
0.30 of a book / hour or 3/10 of a book per hour.
Step-by-step explanation:
Usually I tell people to put the numbers into decimals. Unfortunately for this question, it won't work. So we have any choice but to do it with fractions.
r = amount / time
amount = 1/4
time = 5/6
r = [tex]\frac{\frac{1}{4} }{\frac{5}{6} }[/tex]
Invert the denominator and multiply
r = [tex]\frac{1}{4} * \frac{6}{5}[/tex]
r = 6 * 1 / (5*4) = 6/20 = 3/10
The answer is 3/10 of a book per hour
5/6 of an hour is almost an hour.
1/4 of a book is 0.25 of a book.
3/10 of a book is 0.30 of a book. So it looks like it is just about right.
Under her cell phone plan, Sofia pays a flat cost of $58.50 per month and $4 per gigabyte. She wants to keep her bill at $76.50 per month. Write and solve an equation that can be used to determine gg, the number of gigabytes of data Sofia can use while staying within her budget.
Answer:
To stay within budget, she must use 4.5 gigabytes.
Step-by-step explanation:
Giving the following information:
Under her cell phone plan, Sofia pays a flat cost of $58.50 per month and $4 per gigabyte. She wants to keep her bill at $76.50 per month.
First, we need to establish the total cost formula:
Total cost= 58.5 + 4*x
x= number of gigabytes
Now, we isolate x:
76.5= 58.5 + 4x
18/4= x
4.5= x
To stay within budget, she must use 4.5 gigabytes.
Find the first five terms of the recursive sequence.
Answer:
The first five terms of the recursive sequence are;
5, 12, 19, 26, 33
Step-by-step explanation:
The given sequence is presented as follows;
aₓ = a₍ₓ ₋ ₁₎ + 7
The first term of the sequence, a₁ = 5
Therefore, we have;
a₂ = a₍₂ ₋ ₁₎ + 7 = a₁ + 7 = 5 + 7 = 12
a₃ = a₍₃ ₋ ₁₎ + 7 = a₂ + 7 = 12 + 7 = 19
a₄ = a₍₄ ₋ ₁₎ + 7 = a₃ + 7 = 19 + 7 = 26
a₅ = a₍₅ ₋ ₁₎ + 7 = a₄ + 7 = 26 + 7 = 33
The first five terms of the recursive sequence are therefore;
5, 12, 19, 26, 33.

Answer:
2199.11 (with pi)
2198 (with 3.14)
Step-by-step explanation:
A=2πrh+2πr²
A=2π(14)(11)+2π(14)²
A=2π(154)+2π(196)
A=2(483.56)+2(615.44)

Each figure is composed of large squares and small squares. The side length of the
large square is x. Write an expression for the area of the shaded part of each figure.
Figure A
Figure B
** Please help!!
Hey, did you get the expressions for both figure A and B? If so could you pls write them down below.
9514 1404 393
Answer:
A. x² -4
B. 2x² +8
Step-by-step explanation:
The area of the larger square is the square of its side length, so is x².
A. The area of each of the smaller squares is 1² = 1. There are 4 of them, so their total area is 4×1 = 4. The shaded area is that much less than the area of the larger square, so is ...
x² - 4
__
B. The smaller squares have side length 2, so their area is 2² = 4. There are two of them, so the total area of the smaller squares is 2×4 = 8.
The two large squares have a total area of ...
2 · x² = 2x²
So, the total shaded area is ...
2x² + 8
