Answer:
The answer is below
Step-by-step explanation:
Let x represent the amount of iron, y represent the amount of potassium and z represent the amount of mulch.
Since the supplement weighs 16 lb, hence:
x + y + z = 16 (1)
Also supplement contains thirteen times as much mulch as iron. Therefore:
x = 13z
x - 13z = 0 (2)
The supplement also has twice as much potassium as iron, hence:
x = 2y
x - 2y = 0 (3)
solving equations 1, 2 and 3 simultaneously gives:
x = 10.1 lb, y = 5.1 lb, z = 0.8 lb
This means that the soil supplement contains 0.8 lb of mulch

Answer:
Slope: -3
Equation: [tex]y=-3x-5[/tex]
Step-by-step explanation:
As x increases by 1, your y decreases by 3, making the rise over run [tex]-3/1=-3[/tex]. That becomes the m in your y=mx+b equation, and since you have the y intercept, you can just plug and chug.
If I helped, a brainliest answer would be greatly appreciated!

A sphere is rolled between two sharp, parallel blades that are 77 centimeters apart. Both blades cut off a piece of the sphere cleanly, leaving two parallel circular faces with radii of 39 and 60 cm. What is the radius of the sphere?
Answer:
The radius of the sphere is approximately 62.71 cm
Step-by-step explanation:
The question relates to the definition of a sphere
The given parameters are;
The distance between the sharp parallel blades through which the sphere is rolled = 77 centimeters
The radii of the circular faces left by cutting the sphere with the blade = 39 cm and 60 cm
From the triangles formed by the cross-section of the sphere, we have;
AB ║ DE Given
∠A ≅ ∠E, ∠D ≅ ∠B Alternate angles
∠C ≅ ∠C by reflective property
∴ ΔABC ~ ΔDCE by Angle-Angle similarity theorem
CF/CG = AB/DE = 78/120 = 13/20
CF = CG × 13/20
CF + CG = 77
∴ CG × 13/20 + CG = 77
33·CG/20 = 77
∴ CG = 140/3
CF = 13/20 × CG = 13/20 × 140/3 = 91/3
CF = 91/3
The diameter of the sphere AE = AC + EC
By Pythagoras's theorem
AC = √(FA² + CF²) = √(39² + (91/3)²) = 13·√(130)/3
EC = √(CG² + GD²) = √((140/3)² + 60²) = 20·√(130)/3
∴ AE = AC + EC = 13·√(130)/3 + 20·√(130)/3 = 11·√(130)
The diameter, 'D', of the sphere, AE = 11·√(130)
The radius of the sphere = D/2 = 11·√(130)/2 ≈ 62.71 cm

what is the value of 2^-3 as a fraction
Answer:
1/8
Step-by-step explanation:
2⁻³ = 1 / 2³ = 1 / (2*2*2) = 1/8
so the minus sign in the exponent means you can put that factor in the denominator without the minus sign.

Draw fraction strips to add 1/4 and 1/6 Write an equation.
Answer:
fraction strips would just be;
1 box split into 12 parts because 12 is the common denominator, and 1/4 is equal to 3/12, so you would shade in 3 of the parts, and then 1/6 = 2/12, so you would shade in 2 parts. In the end, you should have a box (or rectangle) with 12 parts, and only 5 of those parts should be shaded in.
The equation would be as follows:
1/4+1/6 = 3/12+2/12 = 5/12

Answer:
Slope: 2/3
Step-by-step explanation:
A slope is rise over run. You first have to get two perfect points, which I got (1,2) and (4,4). The rise is how much does it goes up and the run it's how much it goes to the side. Since the line it's going up, it is positive. The rise is 2 and the run is 3.
Solve the system of linear equations using elimination.
10x + 7y = 12
8x + 7y = 18
A) (3, 6)
B) (3, −6)
C) (−3, 6)
D) (−3, −6)
Answer:
C. (-3,6)
Step-by-step explanation:
Take 10x + 7y = 12 as first equation and 8x + 7y = 18 as second equation.
Subtracting both equations, you will get
10x + 7y - 8x - 7y = 12 - 18
2x = -6
x = -3
Substitute value of 'x' in any of the given equation :-
10x + 7y = 12
10 * -3 + 7y = 12
7y = 12 + 30
y = 42/7
y = 6
Answer:
C) (−3, 6)
Step-by-step explanation:
10x + 7y = 12 ___ (−3, 6)
10×(-3) + 7×6 = -30 + 42 = 42 - 30 = 12
8x + 7y = 18 ___ (−3, 6)
8×(-3) + 7×6 = -24 + 42 = 42 - 24 = 18

Answer:
Jerry's weight is 36kg and tom's weight is 66kg
Step-by-step explanation:
According to the given condition:
Let,tom's weight =x
Jerry's weight=y
So,
X=2y-6 ---(1)
X+y=102-----(2)
Put value of x from eq 1 in 2
2y-6+y=102
3y-6=102
3y=102+6
3y=108
Y=108/3=36
Jerry's weight is 36.
Put value of y in eq 1
X= 2(36) -6
X=72-6
X=66
So, Tom's weight is 66kg

This week at the farmers market the price of oranges per pound decreased by 20% compared to last week if the price of oranges this week is $3.89 which equation would represent the sales price of oranges?
Answer:
Orange per pound= $4.86
Step-by-step explanation:
Giving the following information:
Decrease rate= 20%
Price this week= $3.89 per pound
To calculate the price of oranges last week, we need to use the following formula:
Orange per pound= price this week / (1 - decrease rate)
Orange per pound= 3.89 / (1 - 0.8)
Orange per pound= $4.86

Answer:
Total=110 in²
Step-by-step explanation:
Basically just do all of the shapes individually so the triangles would equal 7 each b/c 4x3.5 divided by 2 so those would be 14 and the rectangles eahc equal 32 so multiply that times 3 and u get 96 then add the two triangles (7 each) which gets u 110 in²
