Step-by-step explanation:
It will take a time 0f 5.5 hours to pick 40 bushels of apple if they worked together.
What is Proportion?Proportions are defined as the concept where two or more ratios are set to be equal to each other.
Suppose we have two ratio p : q and r : s.
If both these ratios are proportional, then we can write it as p: q : : r : s.
This is same as p : q = r : s or p/q = r/s
Given that,
Amount of bushels picked by Maria in 10 hours = 40
Amount of bushels picked by Maria in 1 hour = 40/10 = 4
Amount of bushels picked by Kayla in 12 hours = 40
Amount of bushels picked by Maria in 1 hour = 40/12 = 3.333
Amount of apple picked by both Maria and Kayla in 1 hour if they worked together = 4 + 3.333 = 7.333
Let x be the time taken to pick 40 bushels of apple by both.
Using proportional concept,
x / 40 = 1 / 7.333
x = 40 / 7.333
x = 5.4548 ≈ 5.5 hours
Time taken if they both worked together is 5.5 hours.

When a force of 30 N acts on a certain object the acceleration of the object is 5 m/s^2 if the acceleration becomes is 8m/s ^2 what is the force
Answer:
48 N
Step-by-step explanation:
The equation for force is
F = m * a
where F is force, m is mass, and a is acceleration
30N = m * 5m/s²
m = 6 kg
F = 6kg * 8m/s² = 48 N

Find the missing angle B
Answer:
The missing angle B:
m∠B = 25⁰Step-by-step explanation:
Given the angles
A = 100⁰
C = 55⁰
B = ?
We know that the sum of the angles of triangles is 180⁰.
so
A + B + C = 180⁰
100⁰ + B + 55⁰ = 180⁰
B = 180⁰ - 55⁰ - 100⁰
B = 25⁰
Therefore, the missing angle B:
m∠B = 25⁰

Violet owns a food truck that sells tacos and burritos. She only has enough supplies to make 120 tacos or burritos. She sells each taco for $3.25 and each burrito for $7.50. Violet must sell no less than $570 worth of tacos and burritos each day. Also, she must sell a minimum of 30 tacos. If x represents the number of tacos sold and y represents the number of burritos sold, write and solve a system of inequalities graphically and determine one possible solution.
Answer: y>~ 570-3.25x/ 7.50
y>~ -13/30x
x>~30
Step-by-step explanation:
The solution to the inequality in the graph has been shown.
What is inequality?Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Here,
According to the question,
x + y ≤ 120
x = 120 - y,
x ≥ 30
Or
3.25x+ 7.50 ≥570
Thus, the solution to the inequality in the graph has been shown.

hope this helps :)
please mark branliest
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
To find the scale factor of a dilation, we first have to find two corresponding sides. For example, the top edge of the black shape corresponds with the top edge of the green shape. The length on the black shape measures 7 units and the length on the green shape measures 14 units.
Now, we divide the length taken from the figure by the length taken from the original shape.
14/7=2
Therefore, the scale factor of the dilation is 2.

What’s the domain and range of this graph?
Given:
The graph of a downward parabola.
To find:
The domain and range of the graph.
Solution:
Domain is the set of x-values or input values and range is the set of y-values or output values.
The graph represents a downward parabola and domain of a downward parabola is always the set of real numbers because they are defined for all real values of x.
Domain = R
Domain = (-∞,∞)
The maximum point of a downward parabola is the vertex. The range of the downward parabola is always the set of all real number which are less than or equal to the y-coordinate of the vertex.
From the graph it is clear that the vertex of the parabola is at point (5,-4). So, value of function cannot be greater than -4.
Range = All real numbers less than or equal to -4.
Range = (-∞,-4]
Therefore, the domain of the graph is (-∞,∞) and the range of the graph is (-∞,-4].

Find the perimeter of a rectangle whose length is 4 cm greater than its height, and whose area is 60 cm².
Answer:
Perimeter of the rectangle = 32 cm
Step-by-step explanation:
Explanation:-
Let the height of the rectangle = 'x' cm
Thus the length of the rectangle = x + 4 cm
Perimeter of the rectangle = 2 ( length + height )
Area of the rectangle = length X height
Given area of the rectangle = 60 cm²
( length X height ) = 60
( x + 4) x =60
x² + 4 x - 60 =0
x² + 10 x- 6 x - 60 =0
x ( x+10) - 6 ( x + 10 ) =0
(x+10) ( x -6 ) = 0
x = -10 and x =6
we can choose x =6
The height of the rectangle(H) = 'x' = 6 cm
The length of the rectangle (L)= 6 + 4 = 10cm
Perimeter of the rectangle = 2 ( length + height )
= 2 ( 10 + 6 )
= 32 cm
∴ Perimeter of the rectangle = 32 cm
Answer:
32 cm
Step-by-step explanation:
height = x
length = x+4
x(x+4)=60
x^2 +4x=60
make it into quadratic formula
x^2 + 4x - 60 =0
a=1
b=-4
c=-60
4^2-4*1*(-66)
discriminant equals to 256
square root of 256 equals to 16
x=-4+16/2 = 6
x=-4-16/2 = -10
we will use 6
length is x+4 so 6+4 = 10
width is x = 6
10 plus 10 = 20
6 plus 6= 12
20+12=32 cm

Dr. Bethea has 11 pieces of fruit to give out to his 3 children. He wants to give each child the same number of pieces of fruit. How many pieces of fruit will be left over after he gives them out?
Answer:
2
Step-by-step explanation:
Since in this case they aren't going to cut up the fruit, you find how many times 3 will go into 11 evenly. 3x3=9 which is the largest multiple of 3 that will fit into 11. 11 pieces subtract 9 pieces given to children = 2 pieces left. Hopefully this helps.
