Answer:
There are 29 chickens and 19 sheep.
Step-by-step explanation:
Samantha has chickens and sheep on her farm.
Let the number of chickens be c.
Let the number of sheep be s.
Each chicken has one head and each sheep has one head.
She looked out one day and counted 48 animal heads. Each chicken has one head and each sheep has one head.
This means that the number of chickens and sheep add up to 48:
c + s = 48 ____________(1)
She also counted 134 legs. Each chicken has one head and each sheep has one head. This means that:
2c + 4s = 134 ________(2)
From (1),
c = 48 - s ____________ (3)
Put (3) in (2):
2(48 - s) + 4s = 134
96 - 2s + 4s = 134
Collecting like terms:
2s = 134 - 96
2s = 38
s = 38 / 2 = 19
Putting this back in (3):
c = 48 - 19
c = 29
There are 29 chickens and 19 sheep.
Evaluate this expression.

Jada is visiting new york city to see the empire state building she is 100 feet away when sge spots it.To see the top she has to look up at an angle of 86.2 dehrees how tall is the empire state building
Answer:
Height of the empire building = 1505.57 ft
Step-by-step explanation:
Jada is visiting new York city to see the empire state building . She is 100 ft away when the she spots it. To see the top she has to look at an angle of 86.2° . The illustration forms a right angle triangle.
The height of the empire can be gotten below.
the adjacent side of the triangle formed = 100 ft
The side we are looking for is the opposite side which is the height of the empire state building. The angle formed is the angle of elevation from the ground to the top which is 86.2°
Using SOHCAHTOA principle the height can be gotten with the tangential degree.
tan 86.2° = opposite/adjacent
tan 86.2° = a/100
a = 100 tan 86.2
a = 100 × 15.0557227245
a = 1505.57227245
a ≈ 1505.57 ft
Height of the empire building = 1505.57 ft

Step 1) Divide the figure into separate shapes
Long rectangle: 27 x 5
Triangle: 3 x 4
Middle rectangle: 15 x 7
Small rectangle: 6 x 3
Step 2) Find the area of each shape
Long rectangle: A = 27 x 5 = 135
Triangle: A = 1/2 x 3 x 4 = 6
Middle rectangle: A = 15 x 7 = 105
Small rectangle: 6 x 3 = 18
Step 3) Add all of the areas together
A = 135 + 6 + 105 + 18 = 264 square feet

Mr. Green tells you that a right angle has a hypotenuse of 13 and a leg of 5. She asks you to find the other leg of the triangle. Whats is your answer??
Answer:
Length of leg ⇒ 12
Step-by-step explanation:
Knowing this is a right angle triangle, let us apply Pythagorean Theorem to solve for the length of this other leg, which we can assign as x;
x^2 + 5^2 = 13^2 ⇒ square 5 and 13,
x^2 + 25 = 169 ⇒ subtract 25 from either side of equation,
x^2 = 144 ⇒ Take square root on either side,
Solution; Length of leg ⇒ 12
A student got 78 marks out of a possible 120. Express the students mark as a percentage
The student's mark can be expressed as 65%.
To express the student's mark as a percentage, you need to divide the number of marks obtained by the possible marks and multiply by 100.
In this case, the student got 78 marks out of a possible 120.
Percentage = (Marks Obtained / Possible Marks) * 100
Percentage = (78 / 120) x 100
Percentage = 0.65 x 100
Percentage = 65%
Therefore, the student's mark can be expressed as 65%.

John assignments in value of his car overtime the equation for the line of best fit is approximate as Y represents 2.9 X +17.7 where y represents the value in thousands of dollars what values complete the Residual table
Answer:
For the given equation of the line of best fit, the values that complete the table are as follows
An equation for a line of best fit follows the same guidelines as a linear function where 'y' represents the total (value), 'x' represents time (years), -2.9 is the rate, and 17.7 is the starting value. The table indicates that for any year, there is a given value, but what we are solving for is the predicted value. The residual is the different between the given and predicted values. So, for 'a', we need to solve for the 'y' in our equation by replacing 'x' with '1', multiplying by -2.9 and adding 17.7. This gives us 14.8. For 'b', we simply need to subtract the given and predicted values to get a residual of 0.1. For 'c', we again solve for 'y' by replacing 'x' with '3' in our given equation to get 9. And, for 'd' we subtract the given value of 5 and the predicted value of 6.1 to get 1.1.
answer-
a = 14.8
b = 0.1
c = 9
d = -1.1

An online clothing store is offering free shipping on orders over $75 you want to purchase t shirt for $9.85 and a pair of pants for$56.00 the shipping on this order will be 20% of the total should you purchase a second t shirt? Explain your answer
Answer:
Buy Two tshirts and a pair of pants....
Step-by-step explanation:
Total purchase -
$9.85 + $56.00 = $65.85
Shipping charges is 20% -
65.85 * 0.2 = 13.17
Total (including shipping) = $79.02
If you purchace two t shirts and a pair of pants then you dont have to pay for the shipping therefore,
Total purchase will be -
$9.85 + $56.00 + $9.85 = $75.70
Puchasing 2 tshirts will be $3.32 cheaper....
Answer:
You should buy a second t-shirt.
Step-by-step explanation:
The total without shipping comes out to $65.85. Add the 20% shipping by multiplying .20 by the total, $65.85, and you get $65.85 plus $13.17, the total being $79.02. Now, if you added another shirt for $9.85, your total comes out to $75.70, which barely qualifies for free shipping. In other words, yes, you should purchase a second shirt because you would actually save money, almost $4.

Write the equation of the hyperbola centered at the origin with focus (74, 0) and asymptote y=-7/5x
The equation of the hyperbola is =x^2/a^2-y^2/b^2=1
The equation of the given hyperbola is; x²/25 - y²/49 = 1
What is the equation of the hyperbola?
We are given;
Focus = (74, 0)
Asymptote; y = -⁷/₅x
Centered at origin
We are given that the general form of equation of a hyperbola is;
x²/a² - y²/b² = 1
Now, we know that the equations of the asymptotes are;
y = ±(b/a)x

Answer:
The answer is 5 and 7
Step-by-step explanation:
write an equation of the line that passes through the point (4,7) that is parallel to the line y = 3x+1
Explanation:
The given line y = 3x+1 has a slope of 3 as it is in the form y = mx+b
Any line parallel to this given line will also have a slope of 3. Parallel lines have equal slopes but different y intercepts.
Using m = 3 and (x,y) = (4,7), find the value of b
y = mx+b
7 = 3*4+b
7 = 12+b
12+b = 7
b = 7-12
b = -5
We have y = mx+b update to y = 3x+(-5) or y = 3x-5
Plug in x = 4 and you'll have y = 3x-5 turn into y = 7.

what is the relationship between the base of an exponential function and its rate of growth?
Answer:
growth rate is the number of times the base repeats
Step-by-step explanation:
We have that the general form of the exponential function is of the type:
f (x) = a ^ x
where "a" is the base and "x" is the exponent.
Therefore, the relation they keep to this exponent would be the growth rate since it is the number of times that the base is repeated, which means that the higher "x" is, the more times "a" is repeated.
The base of the function "a" is the point where the exponential curve cuts the y-axis while the value of "b" determines the rate of a growth rate pf decline rate.
Exponential functionThe standard exponential function is expressed as y = ab^x
where:
a is the y-interceptb is the ratex is the time taken.The base of the function "a" is the point where the exponential curve cuts the y-axis while the value of "b" determines the rate of a growth rate pf decline rate.

Simplify cos[arccsc((2√3)/3)].
Answer:
1/2Step-by-step explanation:
Given the expression cos[arccsc((2√3)/3)]
let y = arccsc((2√3)/3)
Taking cosec of both sides we have;
cosecy = cosec[arccsc((2√3)/3)]
cosecy = (2√3)/3
1/siny = (2√3)/3
sin y = 3/2√3
Rationalizing 3/2√3
= 3/2√3 *√3/√3
= 3√3/2*3
= 3√3/6
= √3/2
siny = √3/2
y = arcsin(√3/2)
y = 60°
Since y = arccsc((2√3)/3) = 60°
cos[ arccsc((2√3)/3)] = cos60°
cos60° = 1/2

You pick a card at random, put it back, and then pick another card at random.
What is the probability of picking a number less than 3 and then picking a number greater than 1?
Write your answer as a percentage.
__%
Your answer would be 37.5%
For the first card you picked, the probability of picking a number less than 3 is 2/4 = 1/2, because there are 2 cards that are less than 3 and a total of 4 cards.
When picking the second card, it is still out of 4 because you replaced the first one, so the probability of picking a card greater than 1 is 3/4 because there are 3 cards that are greater than 1 out of a total of 4.
Therefore the total probability would be 1/2 × 3/4 = 3/8. To find this as a percentage we just multiply by 100, and this gives us 37.5%.
I hope this helps!
Answer:
You have three card : 1, 2, 3 and 4.
You first pick one card randomly, the probability of picking a number less than 3 is:
P = 2/4
You then pick a second card after putting the first card back, the probability of picking a number greater than 1 is:
P = 3/4
=> The probability of picking a number less than 3 and then picking a number greater than 1:
P = (2/4) x (3/4) = 3/8
