Answer:1407.4 rounded to nearest tenth
Step-by-step explanation:
Farmer Brown has 42 animals, which are cows and chickens. They have a total of 120 legs. Write a system of equations, show your work, and solve for the number of chickens Farmer Brown has.
Answer:
The system of equations is:
x + y = 42
4x + 2y = 120
And there are 24 chickens.
Step-by-step explanation:
We know that the total number of cows (x) plus the total number of chickens (y) is 42, because Farmer Brown has 42 animals.
We also know that cows (x) have 4 legs and so 4 times the number of cows is the number of cow legs. And chickens (y) have 2 legs, so the number of chickens times two represents the total chicken legs. The sum of 4x + 2y is 120 because there are 120 legs in total.
To solve the system of equations, first solve each equation for y.
In the first equation:
x + y = 42
Subtract x from both sides to isolate y.
y = 42 - x
Second equation:
4x + 2y = 120
Subtract 4x from both sides
2y = 120 - 4x
Divide both sides by 2
y = 60 - 2x
Now that the y's are isolated in both equation, you can put them into 1 equation. Where y = y:
y = 42 - x
y = 60 - 2x
42 - x = 60 - 2x
Add 2x to both sides
42 + x = 60
Subtract 42 from both sides
x = 18
Since x is the number of cows, we know that Farmer Brown has 18 cows.
Now we can substitute the x value into one of the equations:
y = 42 - x
y = 42 - (18)
y = 24
The number of chickens is represented by y, so there are 24 chickens.

Write a slope-intercept equation for a line passing through the point (4, -2) that is parallel to the line 4x + 5y = 9. Then write a second
equation for a line passing through the point (4, - 2) that is perpendicular to the line 4x + 5y = 9
Answer:
7y = -4 x + 8
y = -(4/7) x + /7
so m = -4/7
y = -(4/7)x + b
-2 = -(4/7)(4) + b
-14/7 + 16/7 = b
b = 2/7
so
y = -(4/7)x + 2/7
7y = -4x + 2
for the second one
m = -(-7/4) = 7/4
so
y = (7/4) x + b
now put x = 4 and y = 2 in again to find b

x=360-111-53-84=112
A box measures 18 inches wide by 9 inches deep. The height of the box is 1 1/2 feet. What is the volume of the box? Remember if ft is equivalent to 12 in.
Answer: 2,916 inches³
Step-by-step explanation:
The volume of a box is:
= Length * Width * Height
But all of these have to have the same units for it to work. This means that the height of the box will have to be converted to inches :
1 ft is 12 inches so:
= 1¹/₂ * 12
= 3/2 * 12
= 18 inches
Volume is therefore:
= 18 * 9 * 18
= 2,916 inches³

Which conclusion is best supported by the data in the table ? QUICK
Answer:
:An object floats in water if its mass is less than
its volume.
as density =mass/volume
Answer:
Option D
Step-by-step explanation:
The table is meaningless for you if you know the basics of density
density =Mass/VolumeWater has density 1g/cm³
The density should be less than 1 in order to float
Hence mass must be less than volume- 3/5 - 1/5
in simpliest form
Answer:
−4/5
Step-by-step explanation:
3/5+1/5 Combine, 3+1/5 Simplify, 4/5
A circle has a center at A (-3,4) and radius of 4 units. What is the equation of the circle? Show work!
Answer:
The equation of the circle is (x+3)^2 + (y-4)^2 = 16.
Step-by-step explanation:
The equation of a circle can be calculated if the center and the radius are known. The equation of a circle is given by (x-h)² + (y-k)² = r²
Where (h, k) = center coordinates and r = radius.

A community center rents thier hall for special events. They charge a fixed fee of $200 plus an hourly fee of $22.50. Lin has $300 to spend on renting the hall for a fundraiser white and solve an inequality that represents this situation
Answer
[tex]300 \geqslant 22.5x + 200[/tex]
Step-by-step explanation:
300 is less than or equal to 22.5x + 200
the budget is 300 so you can't go past that number. the appropriate inequality sign for this would be less than or equal to the following equation: $22.5 x (where x= number of hours) + the fixed fee of $200
don't include $ (or other units of measurements) in equations!!

Find the area of each circle. Round to the nearest tenth.
Answer:
A≈50.27
Step-by-step explanation:
Using the formulas
A=πr2
d=2r
Solving forA
A=1/ 4πd^2=1/ 4·π·82≈50.26548
Answer:
Area= 50.3cm^2
Step-by-step explanation:
Use the area of a circle formula A= πr²
Then plug in your radius which is half of your diameter.
A=π(4)² = 50.3 cm²
