Answer: The answer would be 4 biking outfits o=4

Step-by-step explanation:

First add all the money he spent excluding the outfits. The answer would be 315.72. Then subtract 600 and 315.72 = 284.28. Last multiply 71.07 by 4 which gets you 284.28. The EXACT amount he has left. Answer is he can be 4 new biking outfits within his budget. Hope I could help!

A pharmacist wants to mixture of 40 % saline solution with a 12% saline solution to get 119 ml. of a 32% saline solution. He used 85 ml of 40% saline solution and 34 ml of 12% saline solution.

Mixture word problems require you to combine two or more separate items, and then calculate some quantity of the resulting mixture (such as a percentage, price, or number of liters, for example). There will always be some type of "rate," like miles per hour or price per pound. Mixtures are substances that contain two or more distinct substance categories. To separate them, utilize physical tools. Examples include air, different gases, a mixture of sugar and water, a solution of salt and water, and so on.

Given,

A pharmacist wants to mixture of 40 % saline solution with a 12% saline solution to get 119 ml. of a 32% saline solution.

Equation:

X + y = 119

y = 119 - x

0.40x + 0.12y = 119 of 0.32

0.40x + 0.12y = 38.08

Using y = 119 -x

0.40x + 0.12(119 - x) = 38.08

0.40x + 14.28 - 0.12x = 3808  Eq(2)

0.28x = 23.8

x = 85

y = 119 - 85

y = 119 - 85

y = 34

Equating values in equation (2),

0.40(85) + 0.12(34)

34 + 4.08

38.08

A pharmacist wants to mix a 40 % saline solution with a 12% saline solution to get 119 ml. of a 32% saline solution. He used 85 ml of 40% saline solution and 34 ml of 12% saline solution.

Analyzers should use the Alpha aesthetic.

Using the Alpha aesthetic, specific points on a scatterplot are more transparent than others to highlight specific data points.

What is a scatterplot?

A scatter plot is a set of points plotted along a horizontal and vertical axis. In statistics (also known as variables), scatter plots are crucial to demonstrating whether a correlation exists between observational quantities or phenomena.

A scatter plot  plots data points on a horizontal and vertical axis to demonstrate one variable's influence on another. Each row in the data table is represented by a marker whose position is determined by the values of the columns on the X and Y axes.

Using a scatter plot, this line indicates the prevailing direction of a phenomenon. In a scatter plot, a trend line can be used to highlight the direction and speed of price changes.

The distance between the two cars varies at a speed of 65 m/h after two hours.

Let y represent the car's southward travel distance.

Let x be the distance traveled by the westbound automobile.

Allow a to be the distance between the two vehicles.

A right-angled triangle can be used to symbolize these three distances. So, we can state:

a^2 = x^2 + y ^2

Given that the distances vary with respect to time, let's make a distinction.:__________(1)

2a da/dt = 2x dx/dt +2y dy/dt

Rate of distance change between two cars, da/dt

The car is traveling west (dx/dt) at 25 m/h, while the car traveling south (dy/dt) is traveling at 60 m/h.

Therefore:

dy/dt = 60 m/h and dx/dt  = 25 m/h

The separation between the two cars will be after two hours:

y = 3* 60 = 180 miles

x = 3 * 25 = 75 miles

Therefore:

a^2 = x^2 + y ^2

a^2 = 75 ^2+ 180 ^2

a= [tex]\sqrt{5625 + 32400}[/tex]

a= 195

From (1):

195(da/dt) = 75(25) + 180(60)

195(da/dt) = 1875 + 10800 = 12675

da/dt = 12675 / 195 = 65 m/h

As a result, after two hours, the two automobiles' separation is varying at a speed of 65 m/h.

The value of x in the given isosceles triangle is x = 15

From the question, we are to determine the value of x.

From the given information,

The length of the base of the isosceles triangle is x

Also,

The length of a leg is 4x - 3

Since, the length of the legs of an isosceles triangle are equal,

Then,

The length of the other leg is 4x - 3

Also, form the given information,

The perimeter of the triangle is 129

Thus,

x + 4x - 3 + 4x - 3 = 129

Now, solve for x

x + 4x - 3 + 4x - 3 = 129

Collect like terms

x + 4x + 4x = 129 + 3 + 3

9x = 135

Divide both sides by 9

9x/9 = 135/9

x = 15

Hence, the value of x is 15

The function rule for each are:

f(x) = -2x - 6

g(x) = 5x - 4

f(x) is less than g(x), in terms of slope, while in terms of y-intercept, f(x) is greater than g(x).

The rule of a function can be written in slope intercept form as, f(x) = mx + b, where the slope is m and the y-intercept is the value of b.

To write the function rule for f(x), substitute m = -2 and b = -6 into f(x) = mx + b:

f(x) = -2x - 6

Find the slope of the function g(x) whose graph is given:

Slope of g(x) = rise/run = 5/1 = 5

m = 5

The y-intercept is at y = -4, therefore b = -4.

To write the function rule for g(x), substitute m = 5 and b = -4 into g(x) = mx + b:

g(x) = 5x - 4

In terms of slope, f(x) is less than g(x)

In terms of y-intercept, f(x) is greater than g(x).

for an ordered pair (x comma y )in a relation, the x element represents the horizontal axis.

The solution to the linear system of equation is x = 3, y = 5, and z = -0.5

A system of linear equations is a set of linear equations that involve the same variable and which work or are operated (simultaneously) together

The system of linear equation is presented as follows;

2·x - 3·y + 6·z = -12...(1)

5·x + 2·y - 8·z = 29...(2)

7·x + 6·y + 4·z = 49...(3)

Multiplying equation (1) by 5 and equation (2) by 2, we get;

5 × Equation (1) ⇒ 10·x - 15·y + 30·z = -60...(4)

2 × Equation (2) ⇒ 10·x + 4·y - 16·z = 58...(5)

Subtract equation (4) from equation (5), to get;

10·x - 10·x + 4·y - (-15·y) - 16·y - 30·z = 58 - (-60) = 118

19·y - 46·z = 118...(6)

Multiplying equation (1) by 7 and equation (3) by 2, we get;

7 × Equation (1) ⇒ 14·x - 21·y + 42·z = -84...(7)

2 × Equation (3) ⇒ 14·x + 12·y + 8·z = 98...(8)

Subtracting equation (7) from equation (8), we get;

14·x - 14·x + 12·y - (-21·y) + 8·z - 42·z = 98 - (-84) = 182

33·y - 34·z = 182...(9)

Multiplying equation (6) by 33 and equation (9) by 19, we get;

627·y - 1,518·z = 3,894...(10)

627·y - 646·z = 3,458...(11)

Subtracting equation (10) from equation (11), we get;

627·y - 627·y -646·z - (-1,518·z) = 3,458 - 3,894 = -436

872·z = -436

z = -436 ÷ 872 = -0.5

z = -0.5

From equation (6), we have;

19·y - 46·z = 118

19·y - 46 × (-0.5) = 118

19·y - 46 × (-0.5) = 118

19·y = 118  + 46 × (-0.5) = 95

y = 95 ÷ 19 = 5

y = 5

From equation (1), we get;

2·x - 3·y + 6·z = -12

2·x - 3 × 5 + 6 × (-0.5) = -12

2·x = -12 + 3 × 5 - 6 × (-0.5) = 6

What is the conditional statement?

'If p, then q's statements are examples of conditional statements. In this case, "p" stands for "hypothesis" and "q" for "conclusion."

A converse statement is one that is produced by flipping a conditional statement's hypothesis and conclusion.

So, Converse: If I get sick, I ate too much candy.

An inverse assertion presupposes that each of the original claims is true.

So, Inverse: If I don't eat too much candy, then I will not get sick.

When you reverse the hypothesis and the conclusion in a statement, you have a contrapositive statement that refutes both propositions.

Answer:

A.

Step-by-step explanation:

The area of the figure is 1875 sq.in.

In this question, we need to find the area of the given figure.

the area of the figure = area of rectangle + area of two triangles.

For rectangle,

length =  50 inch and width = 30 in.

Using the formula for the area of rectangle,

A1 = length * width

A1 = 50 * 30

A1 = 1500 sq.in.

For triangle,

base = 1/2 * length of rectangle

so, base = 25 in and height = 15 inch

Using the formula for the area of triangle,

A2 = 1/2 * base * height

A2 = 1/2 * 25 * 15

A2 = 187.5 sq.in.

so, the area of the figure would be,

A = A1 + (2 * A2)

A = 1500 + (2 * 187.5)

A = 1875  sq.in.

Therefore, the area of the figure is 1875 sq.in.
