Jane is choosing between two exercise routines. In Routine # 1, she burns 22 calories walking. She then runs at a rate that burns 5.75 calories per minute. In Routine #2, she does only running, burning 8.5 calories per minute. For what amounts of time spent running will Routine #1 burn at least as many calories as Routine #2? Use t for the number of minutes spent running, and solve your inequality for t.​

Answer:

$6.85

Step-by-step explanation:

$2.60 x 4 is 10.4 and that is how much Maria spends. Akio spends $3.55 less than Maria. So, 10.4 - 3.55 which is 6.85 and that is the answer.

Both the equations cut at the point (- 3.125, - 6.25).

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The equations are,

1) 2(1/5)x - 5

2) y = 2x

Now, We can draw the equations by using tool,

Hence, We get the graph of function 2(1/5)x - 5 shows by green line and y = 2x shows by red line.

Clearly, Both the function are cut at the point (- 3.125, - 6.25).

Solution in da attachment!! :)

The Exterior Angle Theorem states that the measure of an exterior angle of a triangle is equal to the sum of the measures of the 2 nonadjacent interior angles. That means that the measure of angle DEF is equal to the sum of measure of angle C and measure of angle D. Substituting known values gives you 2y + 9 + 6y + 10 = 115, then you can solve

8y + 19 = 115

8y = 96

y = 12

The measure of angle C is 33 degrees, the measure of angle D is 82 degrees, and because the measure of angle DEF is 115 degrees, its supplement angle (DEC) measures 65 degrees.

The value of angles are,

∠ H = 20°

∠ G  = 100°

∠ I = 60°

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

Two triangles are similar.

Now, We have in triangle XYZ,

∠Y = 20°

∠Z = 100°

Hence, ∠ X = 180 - (100 + 20)

∠ X = 60°

Thus, By definition of similarity;

∠ H = ∠ Y = 20°

∠ G = ∠ Z = 100°

∠ X = ∠ I = 60°

Thus, The value of angles are,

∠ H = 20°

∠ G  = 100°

∠ I = 60°

The following compositions are shown below:

Case 1

f ° g (x) = x, g ° f (x) = x

The two functions are inverses of each other.

Case 2

f ° g (x) = x, g ° f (x) = x

The two functions are inverses of each other.

In this problem we need to determine the composition between two functions and determine if both functions are inverses of each other. A composition is defined below:

f ° g (x) = f [g (x)]

Where the independent variable of the function f(x) is substituted by function g(x). Two functions are inverses if and only if the following condition is fulfilled:

f[g (x)] = g[f (x)]

Now we proceed to determine the compositions and relationships for each case:

Case 1

f(x) = 3 · x

g(x) = x / 3

f ° g (x) = 3 · (x / 3)

f ° g (x) = x

g ° f (x) = (3 · x) / 3

g ° f (x) = x

Functions f(x) and g(x) are inverses of each other.

Case 2

f(x) = (x - 3) / 2

g(x) = 2 · x + 3

f ° g (x) = [(2 · x + 3) - 3] / 2

f ° g (x) = 2 · x / 2

f ° g (x) = x

g ° f (x) = 2 · [(x - 3) / 2] + 3

g ° f (x) = (x - 3) + 3

g ° f (x) = x

76 degrees Fahrenheit was found to be equal to approximately 24.4 degrees Celsius using the formula of conversion.

To convert Fahrenheit to Celsius, you can use the following formula:

Celsius = (Fahrenheit - 32) x 5/9

Plugging in 76 degrees Fahrenheit, we get:

Celsius = (76 - 32) x 5/9

Celsius = 44 x 5/9

Celsius = 220/9

Celsius ≈ 24.4

Therefore, 76 degrees Fahrenheit is approximately 24.4 degrees Celsius.

On the Fahrenheit scale, water freezes at 32 degrees Fahrenheit (°F) and boils at 212 °F, at standard atmospheric pressure.

The height of the tower in Alex's drawing is 20.7 centimeters.

A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.

We need to find the height of the tower in Alex's drawing.

Let us multiply the actual height of the tower by the scale factor.

Scale factor = 1 : 4000

Height of the actual tower = 828 meters

Height of the tower in Alex's drawing = 828 meters x (1/4000) = 0.207 meters or 20.7 centimeters.

The number of students who preferred banana chips are 57.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that sixty per cent of the students preferred raisins to banana chips. If there were 95 students in all, the number of the students will be calculated as:-

Number = 95 x 60%

Number = 95 x 60 / 100

The measure of m∠H in the triangle is 85°.

Similar triangles are two triangles that have the same shape but can have different sizes. More specifically, two triangles are similar if their corresponding angles are congruent and their corresponding sides are proportional.

Since ΔABC and ΔFGH are similar, we can say:

m∠A =  m∠F

m∠B =  m∠G

m∠C =  m∠H

m∠A  +  m∠B +  m∠C = 180° (sum of angles in a triangle)

We have m∠A = 50° and m∠B = 45°

50°  +  45°  +  m∠C = 180°

m∠C = 180° - 50° - 45°

m∠C = 85°

Since m∠C =  m∠H

Thus, m∠H =  85°

Annuities are a financial instrument that generates a regular stream of cash. They have both a present and future value dependent upon the value of the cash payment, the number of payment periods and the interest rate. This question does not specify the cash inflow amount so an answer will be generated that can be scaled on multiples of $1000.

Let C represent the cash inflow at the end of each year. The future value (FV) of this cash inflow is given by:

FV = [tex]C[((1+i)^n-1)/i][/tex]

where i is the annual interest rate and n is the number of years.

(a) For i = 5% and n = 7

FV = [tex]C [((1+0.05)^7-1)/0.05][/tex]

FV= C[(1.047100-1)/0.05]

FV = C [8.142008]

(b) For i = 8% and n = 7

FV = [tex]C [((1+0.08)^7-1)/0.08][/tex]

FV = C[(1.713824 - 1)/0.08]

FV = C[8.922803]

(c) For i = 17% and n = 7

FV = [tex]C [((1+0.17)^7-1)/0.17][/tex]

FV = C[(3.001242 - 1)/ 0.17]

FV = C[11.772012]

Therefore, A $1000 cash inflows at the end of each year would have a future value of $8,142.01, $8,922.80 and $11.772012 at the end of the year 7 for interest rates of 5% , 8% and 17% respectively.

The Hypothesis test of probability of the type I error is True.

The Hypothesis test probability of the type II error is False.

The notion of the significance level of a hypothesis test is best described by the probability of observing a sample statistic more extreme than the one actually obtained, assuming the null hypothesis is true. This is also known as the "p-value." A significance level is often set beforehand, such as alpha (α) = 0.05, and if the p-value is less than alpha, the null hypothesis is rejected.

The probability of a type I error is related to the significance level. A type I error occurs when the null hypothesis is rejected when it is actually true. The probability of a type I error is represented by alpha (α) and is the level of significance that was set for the test.

The probability of a type II error is the probability of failing to reject a false null hypothesis. It is represented by beta (β) and depends on the sample size, the true value of the parameter being tested, and the level of significance set for the test.
