Answer:
En total hay 36 gallinas en el gallinero.
Step-by-step explanation:
Dado que si en un gallinero contamos los picos, las crestas y las patas obtenemos 144, para determinar cuántas gallinas hay sabiendo que cada gallina tiene un pico, una cresta y dos patas, se debe realizar el siguiente cálculo:
X + X + 2X = 144
4X = 144
X = 144 / 4
X = 36
Por lo tanto, en total hay 36 gallinas en el gallinero.

Draw the figures with the following dimensions. Then, solve for the missing terms.
9514 1404 393
Answer:
V = 125 m³l = 7.5 cmStep-by-step explanation:
You have not told us the sort of figure you're supposed to draw. If these are cuboids, then their drawings are substantially similar to the one shown in the attachment. Your figures may need to show the units on each of the dimensions.
1. A cube with edge lengths of 5 m has a volume of ...
V = s³
V = (5 m)³ = 125 m³
__
2. A cuboid with the given volume and other dimensions has a length of ...
V = lwh
675 cm³ = l(9 cm)(10 cm)
675 cm³/(90 cm²) = l = 7.5 cm . . . . . . . . divide by the coefficient of l

Write a linear equation in standard form for the line that goes through (2, -3)
and (4, -2).
A. X + 2y = -4
B. y - 3 = {(x - 2
C. x - 2y = 8
D. X+ 4y = 12
9514 1404 393
Answer:
C. x -2y = 8
Step-by-step explanation:
One way you can do this is to use the form ...
(Δy)(x -x1) -(Δx)(y -y1) = 0
where Δx = x2 -x1 = 4 -2 = 2, and Δy = y2 -y1 = -2 -(-3) = 1
This gives ...

You can use any of several other strategies, including finding the slope and y-intercept, then rearranging the equation.
Another strategy that works is to try the answer choices. You might notice that the first given point works in the first equation, so it may make sense to try the second given point in each equation.
The above version of the equation of a line is a variation on one that says the slope of a line is the same everywhere:
[tex]\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{y-y_1}{x-x_1}\ \Rightarrow\ (y_2-y_1)(x-x_1)=(x_2-x_1)(y-y_1)\\\\(y_2-y_1)(x-x_1)-(x_2-x_1)(y-y_1)=0[/tex]
Suppose a normal distribution has a mean or 70 and a standard deviation of 7. What is P(x>=94)? O A. 0.075 O 8. 0.025 c. 0.84 OD 0,16
Answer:
0.025
Step-by-step explanation:
Mean = 79 ; Standard deviation = 7
P(x ≥ 93)
We obtain the ZSCORE :
Zscore = (x - mean) / standard deviation
x = 93
Zscore = (93 - 79) / 7 = 2
P(Z ≥ 2) = 0.02275
The delivery truck drove 5 miles from store A to store B. Then the truck drove 13 miles from store B to the warehouse. If store A is directly south of store B and directly east of the warehouse, how far is store A from the warehouse!
Answer:
The distance from the store A to the warehouse is of 13.93 miles.
Step-by-step explanation:
The delivery truck drove 5 miles from store A to store B
5 miles south.
13 miles from store B to the warehouse.
13 miles east.
The situation can be represented by:
A
B Warehouse
In which the distance of A to B is of 5 miles, and the distance of B to the warehouse is of 13 miles. Thus, the distance of store A to the warehouse is the hypothenuse of a right triangle, with sides 5 and 13.
Using the Pytagorean Theorem:
[tex]h^2 = 5^2 + 13^2[/tex]
[tex]h^2 = 25 + 169[/tex]
[tex]h^2 = 194[/tex]
[tex]h = \sqrt{194}[/tex]
[tex]h = 13.93[/tex]
The distance from the store A to the warehouse is of 13.93 miles.

Answer:
He can have 40 guinea pigs in the store.
Step-by-step explanation:
Since Jonas runs a pet store that sells guinea pigs, and he wants to ensure he has more than 1 pound of dry food for every five guinea pigs he has in the store, and he currently has 8 pounds of dry food, to know how many guinea pigs can he have in the store, the following equation must be performed:
1 = 5
8 = X
8 x 5 = X
40 = X
Therefore, he can have 40 guinea pigs in the store.

A density graph is used to find the probability of a discrete random variable
taking on a range of values.
A. True
B. False
Answer:
False
Step-by-step explanation:
This is false because A density graph is not used to find the probability of a discrete random variable taking on a range of values. This is because you have to use a calculations instead of a graph. The correct how to calculate is: Determine a single event with a single outcome. Identify the total number of outcomes that can occur. Divide the number of events by the number of possible outcomes.
Therefore, it's B ( false).
Based on historical data, your manager believes that 33% of the company's orders come from first-time customers. A random sample of 163 orders will be used to estimate the proportion of first-time-customers. What is the probability that the sample proportion is greater than 0.28
Answer:
[tex]P(x > 0.28) = 1[/tex]
Step-by-step explanation:
Given
[tex]p = 33\%[/tex] --- orders from first time customer
[tex]n =163[/tex] --- samples
Required
[tex]P(x >0.28)[/tex]
First, calculate the mean
[tex]\bar x = np[/tex]
[tex]\bar x = 163 * 33\%[/tex]
[tex]\bar x = 53.79[/tex]
Next, the standard deviation
[tex]\sigma = \sqrt{\bar x * (1 - p)[/tex]
[tex]\sigma = \sqrt{53.79* (1 - 33\%)[/tex]
[tex]\sigma = \sqrt{53.79* (1 - 0.33)[/tex]
[tex]\sigma = \sqrt{53.79* 0.67[/tex]
[tex]\sigma = 6.00[/tex]
For [tex]P(x >0.28)[/tex],
The z score is:
[tex]z = \frac{x - \bar x}{\sigma}[/tex]
[tex]z = \frac{0.28 - 53.79}{6}[/tex]
[tex]z = \frac{-53.51}{6}[/tex]
[tex]z = -8.92[/tex]
So:
[tex]P(x > 0.28) = P(z > -8.92)[/tex]
From z probability:
[tex]P(z > -8.92) =1[/tex]
Hence:
[tex]P(x > 0.28) = 1[/tex]
a water main is to be constructed with a 10% grade in the north direction and a 20% grade in the east direction. determine the angle theta required in the water main for the turn from north to east
Answer:
26.6degrees
Step-by-step explanation:
Given
percent grade through north = 10% (opposite)
percent grade through east = 20% (adjacent)
Get the direction
Using the SOH CAH TOA identity
tan theta = opp/adj
tan theta = 10/20
tan theta = 0.5
theta = arctan (0.5)
theta = 26.6degrees
Hence the required angle is 26.6degrees
A circular sinkhole has a radius of 12 meters. A week later, it has a diameter of 48 meters. How much greater is the circumference of the sinkhole compared to the previous week?
Answer:
B
Step-by-step explanation:
1) initial circumference
radius * 2 * pi = 24 * pi = 75,398224
2) final circumference
diameter * pi = 48 * pi = 150,796447
150,796447 - 75,398224 = 75.36 m

What is the measure of angle y in the figure?
Answer:
y = 27
Step-by-step explanation:
The sum of the two angles is a right angle, which is 90 degrees
y+63 = 90
y = 90-63
y =27
Answer:
The measures of angle y is 30 °.
Step-by-step explanation:
We know that, the sum of two side of right angle is 90 °.
60 ° + y = 90 °
subtract 60 ° from each side
y = 90 ° - 60
y = 30 °
Therefore, the measures of angle y is 30°.
