Arya needs to add 2 gallon of 70% antifreeze must be added to a  3-gallon mixture containing 20% antifreeze to obtain the mixture they need.

What is antifreeze?

Antifreeze is an additive that lowers a liquid's freezing point that is made of water. For cold environments, freezing-point depression is accomplished using an antifreeze mixture. Additionally, common antifreezes raise the liquid's boiling point, enabling higher coolant temperatures.

Let x be the amount of 70% antifreeze to be added, in gallons.

In terms of percentage of antifreeze, we write:

20% of 3 gallons + 70% of x gallons = 50% of (3 + x) gallons

0.2(3) + 0.7x = 0.5(3 + x)

0.6 + 0.7x = 1.5 + 0.5x

0.7x - 0.5x = 1.5 - 0.6

0.2x = 0.4

x = 2

Hence, Arya needs to add 2 gallon of 70% antifreeze must be added to a  3-gallon mixture containing 20% antifreeze to obtain the mixture they need.

Divide both sides by -3.

Step-by-step explanation:

This question is asking you how to get from step 1: [tex]-3(p-7) = -15[/tex] to step 2: [tex]p - 7 = 5[/tex].

We can see that the expression inside of the parentheses (p - 7) didn't go away from step 1 to step 2, and the term that was being multiplied by (p-7) had gone away. The only way you can "get rid" of a multiplied term is by doing the inverse of multiplication, which is division. Thus, you have to divide both sides by -3 to get to step 2.

Median of the data 78 , 56 , 22 , 34 is 45.

The middle value of the observations in a data set , arranged in the order of size is known as the median.

It is calculated differently for odd and even number of observations.

1. For odd no. of observations, it is the middle value .

2. For even number of observations, it is calculated as the average of the middle two values.

In this problem , first we arrange the observations in the order of size i.e. 22 , 34, 56, 78.

Since, here the no. of observations is even , 4. So, the median is the average of middle two values.

Answer:

$0.55/ounce

Step-by-step explanation:

The problem gives us the ratio of cost to ounce. We need to create a proportion (when you set two ratios equal to each other) to solve for one variable of the second ratio.

⭐ The first ratio is [tex]$4.95/9 ounces[/tex], which means that it costs $4.95 for 9 ounces.

⭐ The second ratio is [tex]x/1 ounce[/tex], where x is the cost for 1 ounce of frozen yogurt.

. . . . . . . "per ounce" means "for every 1 ounce"

⭐ We need to set these two ratios equal to each other and solve for x.

. . . . . . . In proportions, keep the units of the numerators and denominators the same. In this case, we'll keep the cost as the numerators and the ounces as the denominators.

Step-by-step explanation:

The surface area of the triangular prism box Makayla decorates is 454.8 square centimeters

The surface area of a solid is obtained by adding together the surface areas of the faces or boundaries that encloses the solid.

The dimensions of the triangular prism are;

Rear rectangle;

Length = 12 cm

Width = 7 cm

Dimensions of side triangles;

Base length = 9 cm

Height = 7 cm

Area of each side triangle = 9 cm × 7 cm = 63 cm²

The dimensions of the rectangle at the bottom of the rectangular prism

Length = 12 cm

Width = 9 cm

Dimensions of the slant surface rectangle at the top of the triangular prism are;

Length = 12 cm

Width = 11.4 cm

The surface area of the box, A, is the sum of the individual surface areas, which can be found as follows;

Step-by-step explanation:

-3x^a  y^f+b z^g+c

Because both have the same base is y, so we add both f and b

Same with z, both have the same base is z, so we have z^g+c

The larger the base of a log function, the closer the graph approaches the asymptote of x = 0.

We know that for a exponential function b^x = y, b is the base, y is the exponent to which the base b is raised and x is the result obtained.

We can write this in logarithmic form as:

log_b(x) = y

A logarithm base is the subscript of the logarithm that carries or raises the exponent.

For example in case of log_(3) 9 = 2, the base here is 3.

The change of base formula is:

log_b(x) = log_c(x) / log_c(b)

Also as we know the bigger the logarithm base, the smaller the curve on the graph. This means, the larger the base of a log function, the closer the graph approaches the asymptote of x = 0.

The log function may increase at a slower rate if the base increases.

Therefore, if the base of a log function is large, the graph approaches the asymptote of x = 0.

The sum of two or more numbers that results in a third number is called a factor.

The factor of [tex]$x^2+\frac{x}{6}-\frac{1}{6}$[/tex] exists 2x + 1.

The definition of a factor is a number that divides another number by itself with no remainder. In other words, if multiplying two whole numbers results in a product, the numbers we are multiplying are factors of the product since the product is divisible by them.

What can split a number exactly are factors. So there is no residual after division. Factors are the sums of two or more numbers that produce a third number. Consequently, a factor is a number that divides another.

The use of more variable factors—those whose values do fluctuate with output—occurs as production rises and falls. Workforce, energy, and directly used raw materials are examples of typical variable components.

Let the given equation be [tex]$& x^2+\frac{x}{6}-\frac{1}{6} \\[/tex]

[tex]$& =\frac{6 x^2+x-1}{6} \\[/tex]

simplifying the above equation, we get

[tex]$& =\frac{1}{6}\left(6 x^2+x-1\right)[/tex]

We will factorize the polynomial by splitting its middle term.

[tex]$& \frac{1}{6}\left(6 x^2+x-1\right) \\[/tex]

[tex]$& =\frac{1}{6}\left(6 x^2+3 x-2 x-1\right) \\[/tex]

simplifying the above equation, we get

[tex]$& =\frac{1}{6}(3 x(2 x+1)-1(2 x+1)) \\[/tex]

[tex]$& =\frac{1}{6}(3 x-1)(2 x+1)[/tex]

[tex]$\frac{1}{6^{}}(3 x-1)$[/tex] and (2x + 1) are factors of [tex]$x^2+\frac{x}{6}-\frac{1}{6}$[/tex]

Answer:

The boats cross paths at the points (1,8) and (4,11)

Step-by-step explanation:

First, we want to find the points of intersection between the two paths. We are given two equations, both in the form y=(equation). Since we want to find the intersection points, we set the two equations equal to each other (since both equal y we can plug one of the equations in for y into the other equation) to get

-x^2+6x+3=x+7

From here, we solve this like a normal quadratic equation, move all variables to one side first

-x^2+5x-4=0

This factors to -(x-1)(x-4)=0, giving us x=1 and x=4

Now we plug these back into one of the original equations (in this case the linear equation is much more simple) to give us the points (1,8) and (4,11)

Here's an example:

x y

-2 -11

-1 -6

0 3

1 -2

To plot these points, start by graphing the point (0,3). This is the y-intercept, where the line crosses the y-axis.

Then, use the slope of the line (-5) to find the next point. For example, if you go one unit to the right on the x-axis (from 0 to 1), the y-value decreases by 5 (from 3 to -2).

Continue graphing points in this way until you have plotted enough points to see the shape of the line. You should see that the line has a negative slope, meaning it goes down from left to right.
