225
45
75

Answers

Answer 1

Answer:

75

Step-by-step explanation:

3 × 5²

= 3 × 5 × 5

= 15 × 5

= 75

Answer 2

Answer:

75

Step-by-step explanation:

This is testing Order of Operations

PEMDAS

In this equation we see E (exponents) and M (Multiplication)

The E comes first so doing the exponent of 5^2 we get 25, because that's the same as 5 * 5

After the E is the M, so we multiple the 25 by the 3, giving you 75.

Choose ALL the angles with a measure less that 90 degrees.

Answers

Answer:

Top left    Top middle     Bottom Left       Bottom right

Step-by-step explanation        

If the angle makes an "L" it is a 90 degrees angle or a right angle

If the angle makes a "V" it is less than 90 degrees or an acute angle

If the angle makes a "Stretched out  V" it is more than 90 degrees or an obtuse angle

The option that represents the acute angle will be option A, option B, option D, and option F.

What is an angle?

The inclination is the separation seen between planes or vectors that meet. Degrees are another way to indicate the slope. For a full rotation, the angle is 360°.

The types of angles are as follows:

If the angle is less than 90° then the angle is known as an acute angle.If the angle is equal to 90° then the angle is known as a right angle.If the angle is more than 90° then the angle is known as an obtuse angle.

Then the option that represents the acute angle will be option A, option B, option D, and option F.

Tyrone went to a basketball game and brought a jersey that was on sale at a 30% discount. He also bought a hat that cost $37.89. Tyrone spent a total of $83.39.

Answers

Guessing we need to find the original cost of the jersey?

83.39 - 37.89 = 45.50 is the sale price of the jersey

x - 0.3x = 45.50 (full price minus 30% of the full price)
0.7x = 45.50, divide by 0.7
x = $65

A population numbers 15,500 and grows at 3.75% per year. Write an exponential model for the growth of this population.

Answers

Answer: [tex]f(x)=15500(1.0375)^x[/tex]

Step-by-step explanation:

The exponential model for growth is given by :-

[tex]f(x)=A(1+r)^x[/tex], where A = initial value , r = growth rate (in decimal), x = time  (in years).

Given: A= 15,500      r= 3.75% = 0.0375

The exponential model for the growth of this population will be :

[tex]f(x)=15500(1+0.0375)^x\\\\\Rightarrow\ f(x)=15500(1.0375)^x[/tex]

hence, the required model: [tex]f(x)=15500(1.0375)^x[/tex]

Describe what the graph and equation look like for each of the parent functions.

Answers

Answer:

there you go there's your answers

Step-by-step explanation:

→A parent function is the simplest function of a family of functions. of this form is y = x2. The simplest parabola is y = x2, whose graph is shown at the right. The graph passes through the origin (0,0), and is contained in Quadrants I and II.

€xample→

For example, you can simplify "y=2*sin(x+2)" to "y=sin(x)" or "y=|3x+2|" to "y=|x|." Graph the result. This is the parent function. For example, the parent function for "y=x^+x+1" is just "y=x^2," also known as the quadratic function.

Mike's car holds 14 2/5 g of gas, averages 20mpg. About how far can Mike's travel if his tank is 1/4 full?

Answers

Solution :

It is given that :

The car of Mike's can hold = [tex]$14 \frac{2}{5}$[/tex] g of gas.

                                            [tex]$=\frac{72}{5}$[/tex] g of gas

∴ [tex]$=\frac{1}{4} $[/tex] th of [tex]$\frac{72}{5}$[/tex] g of gas is  [tex]$=\frac{1}{4} \times \frac{72}{5}$[/tex]

                                          [tex]$=\frac{18}{5}$[/tex] g of gas

                                         

The average distance that the car can travel when the tank is full is = 20 mpg

∴ In  [tex]$\frac{72}{5}$[/tex] g of gas, the car travels = 20 mpg

   In 1 g of gas, the car travels = [tex]$20 \times \frac{5}{72} $[/tex] mpg

   So in  [tex]$\frac{18}{5}$[/tex] g of gas, the car travels = [tex]$20 \times \frac{5}{72} \times \frac{18}{5} $[/tex] mpg

                                                          = 5 mpg

Select all that are equivalent to sin∠GFH

Answers

Answer:

I think sin<GEJ IS equivalent to sin∠GFH

All that are equivalent to sin∠GFH is

D) cos(&lt;EGJ)

"Corresponding angles"

sin(&lt;GEJ)cos(&lt;FGH)cos(&lt;EGJ)

From the image JE and HF are parallel.

So angle GFH and angle GEJ are corresponding angles.

So they are equal.

so, sin(&lt;GFH) = sin(&lt;GEJ).

From triangle GFH, &lt;GFH+&lt;FGH = 90.

So, sin(&lt;GFH) =cos(&lt;FGH).

Again &lt;FGH = &lt;EGJ.

So, sin(&lt;GFH) =cos(&lt;EGJ)

All that are equivalent to sin∠GFH is cos(&lt;EGJ).

Thus, the correct answer is D.

Por un tubo de 2.5 cm de diámetro fluye agua con una repidez de 20 cm/s ¿Cuál es el valor del flujo y el gasto del agua?

Answers

Answer:

El flujo y gasto de agua es aproximadamente 98.175 centímetros cúbicos por segundo.

Step-by-step explanation:

El gasto del agua ([tex]Q[/tex]), medido en centímetros cúbicos por segundo, es el flujo que pasa a través del tubo. La ecuación para determinar el gasto es:

[tex]Q = \frac{\pi}{4}\cdot D^{2}\cdot v[/tex] (1)

Donde:

[tex]D[/tex] - Diámetro del tubo, medido en centímetros.

[tex]v[/tex] - Velocidad del flujo, medida en centímetros por segundo.

Si sabemos que [tex]D = 2.5\,cm[/tex] y [tex]v = 20\,\frac{cm}{s}[/tex], entonces el flujo y gasto del agua es:

[tex]Q = \frac{\pi}{4}\cdot (2.5\,cm)^{2}\cdot \left(20\,\frac{cm}{s} \right)[/tex]

[tex]Q \approx 98.175\,\frac{cm^{3}}{s}[/tex]

El flujo y gasto de agua es aproximadamente 98.175 centímetros cúbicos por segundo.

We need to find the value of  [tex]\theta[/tex] for the given expression. So,

[tex]\tan\theta=\dfrac{5\sqrt{20}}{11}[/tex]

or

[tex]\theta=\tan^{-1}\tan\left(\frac{5\sqrt{20}}{11}\right)\\\\=-2.0083\ radian[/tex]
