Janice has 15 pets. Each of her pets is either a dog or a bird. If her pets have a total of 38 legs, how
many dogs and how many birds does Janice own?
Hi!
These can be set up as systems of equations.
Let b = the number of birds, and let d = the number of dogs.
b + d = 21
2b + 4d = 76 (this is because birds have 2 legs and dogs have 4 legs.)
You can solve this using either elimination or substitution.

Answer:
11/6
Step-by-step explanation:
2x/3 = 1/2
Cross multiply, get 4x = 3, x = 3/4
3y/4 = 3/2
Cross multiply, get 6y = 12, y = 2
x + y = 3/4 + 2 = 11/4
xy = 3/4 * 2 = 3/2
(x + y)/(xy) = (11/4)/(3/2) = 11/4 * 2/3 = 22/12 = 11/6

What number is one-fourth of three hundred and sixty?
A.180
B.45
C.60
D.90
E.360
Hey there!
To find the number that's one-fourth of 360, we should just divide 360 by 4 and get 90.
There's also another way - multiplying fractions.
[tex]\bold{\displaystyle\frac{1}{4} *\frac{360}{1}}[/tex]
In order to multiply fractions, we just multiply the numerator of one fraction times the numerator of the other one; same with the denominator.
Look what happens when I multiply:
[tex]\bold{\displaystyle\frac{360}{4}}[/tex]
We can use mental maths to solve it.
Hence, the answer's 90.
Hope everything is clear.
Let me know if you have any questions!

what is the square root of √ 3⁶/²⁵
Answer:
5
Step-by-step explanation:
The square root of 29.16 is approximately 5.4. Therefore, the square root of √ 3⁶/²⁵ is approximately 5.4.
The square root of a number is a value that, when multiplied by itself, gives the original number.
To find the square root of √ 3⁶/²⁵, we can break it down into simpler steps.
Step 1: Simplify the expression inside the square root. √ 3⁶/²⁵ can be simplified as follows: √(3⁶ / 5²)
Step 2: Simplify the numerator and the denominator separately.
The numerator is 3 raised to the power of 6, which means multiplying 3 by itself six times:
[tex]3^6[/tex] = 3 × 3 × 3 × 3 × 3 × 3 = 729
The denominator is 5 raised to the power of 2, which means multiplying 5 by itself two times: [tex]5^2[/tex] = 5 × 5 = 25
So, the expression becomes: √(729 / 25)
Step 3: Simplify the expression inside the square root.
√(729 / 25) = √(29.16)
Step 4: Find the square root.
The square root of 29.16 is approximately 5.4. Therefore, the square root of √ 3⁶/²⁵ is approximately 5.4.

Find the distance between the following pairs of points. Round the answer to two decimal places (-5,0) and (-5,3)
Answer:
3
Step-by-step explanation:
Use the distance formula to determine the distance between two points.
It is known that 5% of flashlight bulbs manufactured by a certain company are defective. a. Use the normal approximation to estimate the probability that, out of a random sample of 600 lightbulbs, at least 25 are defective. (5 points) b. Use the normal approximation to estimate the probability that, out of a random sample of 600 lightbulbs, fewer than 20 are defective. (5 points)
Using the normal approximation to the binomial, the probabilities are given by:
a) 0.8485 = 84.85%.
b) 0.0244 = 2.44%.
Normal Probability DistributionIn a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.The binomial distribution is the probability of x successes on n trials, with p probability of a success on each trial. It can be approximated to the normal distribution with [tex]\mu = np, \sigma = \sqrt{np(1-p)}[/tex].In this problem, we have that:
There are 600 bulbs, hence n = 600.5% are defective, hence p = 0.05.The mean and the standard deviation of the approximation are given, respectively, by:
[tex]\mu = np = 600(0.05) = 30[/tex]
[tex]\sigma = \sqrt{np(1-p)} = \sqrt{600(0.05)(0.95)} = 5.3385[/tex]
Item a:
Using continuity correction, the probability is P(X > 24.5), which is one subtracted by the p-value of Z when X = 24.5, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{24.5 - 30}{5.3385}[/tex]
[tex]Z = -1.03[/tex]
[tex]Z = -1.03[/tex] has a p-value of 0.1515.
1 - 0.1515 = 0.8485.
0.8485 = 84.85% probability.
Item b:
This probability is P(X < 19.5), which is the p-value of Z when X = 19.5, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{19.5 - 30}{5.3385}[/tex]
[tex]Z = -1.97[/tex]
[tex]Z = -1.97[/tex] has a p-value of 0.0244.
The probability is of 0.0244 = 2.44%.

Find the value of xxx, yyy, and zzz in the parallelogram below.
Answer:
x = 67; y = 121; z = 65
Step-by-step explanation:
x + 1 + 112 = 180
x + 113 = 180
x = 67
y - 9 = 112
y = 121
z + 3 + 112 = 180
z + 115 = 180

Mark is building two separate pig-pens. The width of pig-pen A is w. The length of pig-pen A is 4 feet longer than its width. The width of pig-pen B is 5 feet less than the width of pig-pen A. The length of pig-pen B is 2 times its own width. If the both pig-pens have the same perimeter, then find the dimensions of each pig-pen.
Answer:
The width of pen A is 7 feet,
The Length of Pen A is 11 feet,
The width of Pen B is 6 feet,
The Length of Pen B is 12 feet
Step-by-step explanation:
The width of pen A is 7 feet,
The Length of Pen A is 7 + 4 = 11 feet,
The width of Pen B is 7+4-5 = 6 feet,
The Length of Pen B is 2*(7+4-5) = 12 feet

What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
Vertical shifting of a graph is done by adding any arbitrary constant to the function in shifting.
For example, If shift up by 1 unit, add 1 to the function
If shift down by 4 units, subtract 4 from the function
Given that Δ RTS has a vertices R (10,0) S (3,4) And T(4,2)
The original coordinate of S is (3,4).
To determine the image of S' after a vertical transition two units down and a horizontal transition of four units to the right
The y-coordinate will increase by 4 if we move it to the right.
This will then become 4+4 =8.
If we shift it downward, it will become negative and read as -2.
This will then become 3-2 = 1.
So, the coordinate of S' will be located at (1, 8)
Hence, the new coordinates of S' will be located at (1, 8) after translating 4 units right and 2 units down.

What is the range of the graph?
a. 1 ≤ y ≤ 8
b. 100 ≤ x ≤ 400
c. 100 ≤ y ≤ 400
d. 1 ≤ x ≤ 8
Answer:
C
Step-by-step explanation:
The term range is used when looking for y.
This automatically eliminates the possibility of B and D.
Since y applies only to the vertical aspect of the graph, we can ignore all of the horizontal information (time minutes)
Looking at distance, the bug's lowest point was at 100cm and at its highest point at 400cm
This means the minimum is 100 and maximum is 400
In other words:
100 <= y <= 400
Answer:
C) 100 ≤ y ≤ 400
When we are talking about range, we are talking about y values, so B is disqualified.
When determining range you want the lowest & highest y values.
On this graph the lowest value of y is 100 (seen between 5 and 6 seconds).
The highest value of y is 400 (seen at 8 seconds).
Therefore, 100 ≤ y ≤ 400.
