1. Bank teller Darrin Wentworth counted a deposit with 72 five-, ten- and one-hundred-dollar bills. After counting, Darrin found that the value of the bills was $3,500. He noticed that there was an equal number of five- and ten-dollar bills. How many of each bill was in the deposit?​

Answer: No, it is not proportional.

Explanation:

We can see that Diego opened an account with $20, meaning that there is going to be a y-intercept of 20 in a graph. Therefore, with a y-intercept of 20 and not zero, we can say that there is not a proportional relationship between and time and amount saved for Diego.

The solution to the given inequality that is x+4y<4 is (-8,-2) as it only gives the correct result for the equation.

In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. The equation-like form of the formula 5x 4 > 2x + 3 has an arrowhead in place of the equals sign. It is an illustration of inequity. This shows that the left part, 5x 4, is bigger than the right part, 2x + 3. An inequality in mathematics is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.

Here,

x+4y<4

(-8,-2)

-8+4*-2=-16<4

The provided inequality, x+4y4, has a solution of (-8,-2) because it alone provides the solution to the equation.

The simplest form of the ratio r:h:u is 5 : 8 : 14.

What is the ratio?

A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8.

We have,

r : h  = 5 : 8   .........(i)

h : u =  4:7    ........(ii)

Multiplying the (i) and (ii) by numbers that will make 'h' have the same value in the ratios

Multiplying (i) by 1

(r : h)*1  = (5 : 8)*1

= r : h  = 5 : 8  

Multiplying (ii) by 2

(h : u)*2 =  (4:7) *2

= 8 : 14

the ratio r : h : u in the simplest form = 5 : 8 : 14.

Hence, the simplest form of the ratio r:h:u is 5 : 8 : 14.

So, the answer is A

The inverse of y = √x - 10 + 4 is y = x^2 + 26 + 8x

What in mathematics is inverse?

A function that "undoes" another function is known as an inverse in mathematics. To put it another way, if f(x) produces y, then y will produce x when y is fed into f's inverse function. Invertible refers to a function that has an inverse, which is represented by the symbol f1.

Given that:

J(x) = √x - 10 + 4

y = √x - 10 + 4

now replace x with y

x = √y - 10 + 4

now solve for y , x = √y - 10 + 4

x + 4= √y - 10

Squaring both the side

x^2 + 16 + 8x = y - 10

y = x^2 + 26 + 8x

Hence the inverse of y = √x - 10 + 4 is y = x^2 + 26 + 8x

Converting 7π/21 to degrees will be 60°.

Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both.

A plane angle is measured in degrees, with the letter ° typically used to indicate that one full rotation is equal to 360 degrees. Although it is not a SI unit—the radian is the SI unit of angular measure—it is mentioned as an accepted unit in the SI brochure.

Angles are measured in terms of radians. Angles are measured using the degree and radian units. In calculus and the majority of other branches of mathematics, angles are typically or generally measured in radians.

It should be noted that in order to convert radians yo degrees, you've to multiply by 180/π since a full circle is 360°.

This will be illustrated as:

= 7π / 21 × 180 / π

= 7/21 × 180

y = mx + c.

In the graph given, the function is a straight line with slope and y-intercept.

Taking two points from the graph.

The slope of the equation can be calculated using the points

slope (m) = y₂ - y₁ / x₂ - x₁

m = 1 - 0 / -2 - 5

m = 1 / -7

The slope is -1/7

From the graph, we can see the point in which the line passes through the y - axis and it is known as the y - intercept.

The point on the segment connecting A and B that is 4 times as far from B as it is from A is (-8, 8).

Answer:

or the distance to be 4 times the distance from B as A   the segment must be divided into (4+1) = 5 segments

  so we want the point that is 1/5 of the way from A to B

x    from A   to B   is     2   to   - 6   =   -8 units       1/5 * -8    +  2  =    0.4

y    from A   to B   is     7 to    -3    =   -10 units      1/5 * -10  +  7    = 5    

If a car is traveling at 50 mph due south at a point 1 mile north of an intersection. the radar gun register at -62.6 mph.

Distance can be defined as how far an object is from another object.

Distance of the first car north of the intersection point =y

Distance of the police car west of the intersection  =x

Distance between the cars =s

s² =x² +y²

x=1.4 miles or 0.25 miles

y =1/2 miles or 0.50 miles

Pythagoreans theorem

Distance between cars

s =√x²+y²

s=√(0.25 miles)² +(0.50 miles)²

s =0.559 miles

Hence,

ds/dt = [0.25 miles/ 0.559 miles (-40 mph)] + [0.50 miles/0.559 miles (-50 mph)

ds/dt = -17.89 + -44.7
