Solving linear equations, mixture problem pls help
61.67 oz of the 55% acid solution and 33.33 oz of the 30% acid solution must be mixed to produce 100 ounces of a 43% acid solution.
This is a mixture problem that can be solved using algebra. We can set up a system of equations to represent the amount of each solution being used and the final acid concentration.
Let x be the amount of 55% acid solution and y be the amount of 30% acid solution used.
We can set up the following system of equations:
(55/100)x + (30/100)y = (43/100)(x + y) (Equation 1) represents the final acid concentration.
x + y = 100 (Equation 2) represents the total amount of solution mixed
We can solve for one variable in equation (1) by isolating it and substituting it into equation (2).
Solving for x in equation (1) we get: x = (100*43/100 - y30/100)/55/100
Substituting this value into equation (2) we get: (10043/100 - y30/100)/55/100 + y = 100
Solving for y we get: y = (100*100 - 100*43)/30 = 33.33 oz
And then substituting this value back into the equation x = (100*43/100 - y30/100)/55/100 we get x = 61.67 oz
So, 61.67 oz of the 55% acid solution and 33.33 oz of the 30% acid solution must be mixed to produce 100 ounces of a 43% acid solution.

Therefore , the solution of the given problem of surface area comes out to be 0.2083 yard square.
Exactly what is surface area?A surface is a measurement of how much overall space an object's surface takes up. Surface area of a three-dimensional shape is determined by the total area of its surroundings. Surface area is the term used to describe a triangular shape's entire surface area. The particular area of each face on a cube with six square faces can be added up to determine the cube's surface area. Alternately, you can get the box's dimensions by using the following formula: Surface (SA) equals twice twice twice twice. A three-dimensional shape's surface area is calculated as the sum of all the space it occupies.
Here,
Given : width : 5/6 yard

An equation for a tangent to the graph of y = arcsin(x/2) at the origin is: O y=2 O x=2y O y = 4x Ο πx = 2y
The equation for a tangent to the graph of y = arcsin(x/2) at the origin is y = x.
To find the equation for a tangent to a graph at a certain point, we need to find the slope of the tangent at that point. To do this, we can use the derivative of the function. In this case, the function is y = arcsin(x/2). Using the chain rule, we can find the derivative of this function:
y' = d/dx(arcsin(x/2))
= d/dx(sin^-1(x/2))
= 1/√(1 - (x/2)^2)
Now, to find the slope of the tangent at the origin (0,0), we can plug x = 0 into this derivative:
y'(0) = 1/√(1 - (0/2)^2) = 1
So the slope of the tangent at the origin is 1. To find the equation of the tangent, we can use the point-slope form of a line:
y - y1 = m(x - x1) where,
(x1, y1) is the point at which the tangent touches the graph (in this case, the origin) m is the slope of the tangent.Plugging in the values for the origin and the slope we found above:
y - 0 = 1(x - 0)
or, y = x
So the equation for the tangent is y = x. But the options are incorrect.

When packed with toys and ready for shipment, both kinds of containers have the same number of toys and the same weight. What is the number of toys?
The number of toys is 5 in each container.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Let x be the number of toys in each container.
Weight of one toy car = 6 pounds
Weight of the container in which toy cars shipped = 5 pounds
Weight of x toy cars = 6x
Total weight of the container when toy cars are placed = 6x + 5
Weight of one toy truck = 3 pounds
Container weight = 20 pounds
Weight of x toy trucks = 3x
Total weight of the container when toy trucks are place = 3x + 20
Given that both containers have same weight.
6x + 5 = 3x + 20
6x - 3x = 20 - 5
