How many gallons of a 50% antifreeze solution must be mixed with 70 gallons of 10% antifreeze to get a mixture that is 40% antifreeze?
Answer: 180 gallons needed
Step-by-step explanation:
Zykeith,
Assume x gallons of 50% antifreeze is needed
Final mixture is x + 60 gallons
Amount of antifreeze in mixture is 0.4*(x+60)
Amount of antifreeze added is .5x + .1*60 = .5x + 6
so .5x + 6 = .4(x + 60)
.5x -.4x = 24 -6
.1x = 18
x = 180
Let x be the number of gallons of the 50% antifreeze solution needed. We know that the resulting mixture will be 70 + x gallons. To get a 40% antifreeze mixture, we can set up the following equation:
\({\implies 0.5x + 0.1(70) = 0.4(70 + x)}\)
Simplifying the equation:
\(\qquad\implies 0.5x + 7 = 28 + 0.4x\)
\(\qquad\quad\implies 0.1x = 21\)
\(\qquad\qquad\implies \bold{x = 210}\)
\(\therefore\) We need 210 gallons of the 50% antifreeze solution to mix with 70 gallons of 10% antifreeze to get a mixture that is 40% antifreeze.

(b) On-line gaming system. (You are interested in modeling the number of people playing Halo 4 at any time t.) (c) An airport. (You are interested in modeling the percentage of flights that depart late on any given day).
(a) Any number could represent the amount of current flowing through the capacitor in decimal form. So that the electric capacitor is Continuous.
(b) There are exactly that many players. So On-line gaming system is Discrete.
(c) The number of flights or their proportion depend on the aircraft, which are expressed as whole numbers. So an airport is continuous.
In the question, we have to classify the systems as being either discrete or continuous:
Discrete data, often known as discrete values, is information that only accepts specific values. This type of data, which typically takes the form of whole numbers or integers, can be counted and has a finite set of possible values.
Data that can be measured is referred to as continuous data. There are an endless number of alternative possibilities for the values in this data, which are not fixed.
Nevertheless, the main distinction between discrete and continuous data is that the former has a finite value that can be counted while the latter has an infinite range of possible values that can be measured.

The result to the equation is x = 7.
To find the results of the equation √( 2x- 5) 4 = 1, we can break it step by step
Abate 4 from both sides of the equation
√( 2x- 5) = 1- 4
√( 2x- 5) = -3
Square both sides of the equation to exclude the square root
√( 2x- 5))² = (- 3)²
2x- 5 = 9
Add 5 to both sides of the equation
2x = 9 + 5
2x = 14
Divide both sides of the equation by 2
x = 14/2
x = 7
Thus, the result to the equation is x = 7.
Checking the extraneous result
Substituting x = 7 back into the original equation
√(2(7)-5)+4=1
√(14-5)+4=1
√9+4=1
3+4=1
7 = 1
This equation isn't true, which means that x = 7 is an extraneous result.

A square has a side length of 7 cm. A rectangle has a length of y/8-3cm and a width of 4 cm. The square has the same perimeter as the rectangle. Work out the value of y.
if the square has the same perimeter as the rectangle then the value of y is 92.
How to find the value of y?The perimeter of a square is equal to the sum of all four sides, so a square with a side of 7 cm has a perimeter of 4 * 7 cm = 28 cm.
The perimeter of the rectangle is equal to twice the sum of the length and width. So for a rectangle of length y/8-3cm and width 4cm, the perimeter is 2 * (y/8-3+4) cm = (y/4-3+8) cm = y/4 . +5 cm.
Since squares and rectangles have the same perimeter, the two perimeter formulas can be equal.
28cm = y/4+5cm
You can solve for y by isolating it on one side of the equation.

Answer:
sec B = 17 / 15
Step-by-step explanation:
Sec theta = hyp / adj
sec B = 17 / 15
Answer:
17/15
Step-by-step explanation:
The secant of an angle is the ratio of the hypotenuse to the adjacent angle (it is also the reciprocal of cosine).
secθ=hypotenuse/adjacent
sec(∠B)= hypotenuse/adjacent
The hypotenuse in this triangle is 17, because it is opposite the right angle or the little square.
sec(∠B)=17/adjacent
The side adjacent, or next to angle B is 15.
sec(∠B)= 17/15
This fraction cannot be reduced further, therefore the secant of angle B is 17/15.

Answer:
Step-by-step explanation:
The vertex is at (-3, -1) and the leading coefficient is negative ( because the curve is inverted)
y = -a(x + 3)^2 - 1
One point on the curve is (-2, -3) so
-3 = -a(-2+3)^2 - 1
-3 = -a - 1
-a = -2
So we have
y = -2(x + 3)^2 - 1
y = -2(x^2 + 6x + 9) - 1
y = -2x^2 - 12x - 19.
Solve the equation for the indicated variable. A=r+rvf, for v
Answera=frv+r

To solve for a variable in an equation means that we change the subject of the formula. The solution to the equation for variable v is:
\(\frac{A - r}{rf} = v\)
Given that:
\(A = r + rvf\)
Subtract r from both sides
\(A - r = rvf\)
Divide both sides by rf
\(\frac{A - r}{rf} = v\)
Rewrite as:
\(v=\frac{A - r}{rf}\)

-1,0,1,2A calf raiser mixes a batch of milk replacer for 15 calves. Each calf gets two
quarts of milk replacer. If the calf raiser uses 960 oz. of replacer and needs to
add 34 as much water as milk replacer, how many ounces of water does she need?
Answer:
The calf raiser uses 960 oz of milk replacer for 15 calves, so each calf gets 960 oz / 15 = 64 oz of milk replacer.
To convert this to quarts, we need to divide by 32 (since there are 32 oz in a quart)
64 oz / 32 oz/quart = 2 quarts
Each calf gets 2 quarts of milk replacer and the calf raiser needs to add 34 as much water as milk replacer
So the total amount of water she needs is 2*34 = 68 quarts
To convert the quarts of water to ounces we need to multiply by 32 (since there are 32 oz in a quart)
68 quarts * 32 oz/quart = 2176 oz of water.
So the calf raiser needs 2176 ounces of water to mix with the milk replacer for 15 calves.

Individual object in a set are called
the shortest side of a right triangle measures 7m. The lengths of the other two sides are Consecutive integers. What is the length of the other two sides?
The lengths of the other two sides of the right triangle are 24m and 25m, respectively.
Let's assume the consecutive integers representing the lengths of the other two sides of the right triangle are x and x + 1, where x is the smaller integer. We are given that the shortest side measures 7m. Now, we can use the Pythagorean theorem to solve for the lengths of the other two sides.
According to the Pythagorean theorem, in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides.
Using this theorem, we have the equation:
\(7^2 + x^2 = (x + 1)^2\)
Expanding and simplifying this equation, we get:
\(49 + x^2 = x^2 + 2x + 1\)
Now, we can cancel out \(x^2\) from both sides of the equation:
49 = 2x + 1
Next, we can isolate 2x:
2x = 49 - 1
2x = 48
Dividing both sides by 2, we find:
x = 24
Therefore, the smaller integer representing the length of one side is 24, and the consecutive integer representing the length of the other side is 24 + 1 = 25.
Hence, the lengths of the other two sides of the right triangle are 24m and 25m, respectively.

In a regression analysis, the actual values of Y may be found above or below the regression line. These deviations are called the _____. slope error term variance standard error of the mean standard deviation
Answer:
Error term
Step-by-step explanation:
Given :
In a regression analysis, the actual values of Y may be found above or below the regression line. These deviations are called the _____. slope error term variance standard error of the mean standard deviation
To find :
Fill in the blanks.
Now, In a regression analysis, the actual values of Y may be found above or below the regression line. These deviations are called the Error term.
Because we use the error term in the regression analysis difference between the actual value of \(Y\) and the approximate value of \(Y\) which is above of actual value or below of actual value.
As \(Y\)is an actual value and \(Y_0\) is an approximate value then,
\(|Y-Y_0|\) is an error.
It is a vertical distance between the actual value and the approximate value of \(Y\).
So, the error term is always positive.
Find the percent error if the estimate is $230 and actual amount is $245. Round to the nearest whole percent.
