one half of the birds at the pet store are yellow. Tara buys one of the birds. Then one third of the birds at the pet store are yellow. How many yellow birds were at the pet store before Tara bought one? explain how u know

f(39)=65-100(39)

65-3900

= -3835

Answer:

-3

Step-by-step explanation:

subtract 10 to the 25 so that cancels out the 10, you are left with -5m=15, then you divide the -5m by -5 to cancel it out on both sides. that leaves you with m by itself and once you do the division of 15 by -5 the result is -3

Answer:

220.5 ft²

Step-by-step explanation:

Hello There!

To find the area of the figure we want to split the figure into two shapes that a formula can easily be used to calculate their area

We split it into a rectangle with a length of 12 and a height of 14

and we split it into a trapezoid with base lengths that are equal to 7 and 14 and a height of 5

Now we can easily solve for the area

for the rectangle we use the formula

[tex]A=lw[/tex]

where l = length and w = width

[tex]a=12*14\\12*14=168\\a=168[/tex] so the rectangles area is 168 ft²

Now let's solve for the trapezoid's area

To calculate the area of the trapezoid we use the formula

[tex]A=\frac{a+b}{2} h[/tex]

where a and b = the bases and h = height

all we have to do is plug in the values

[tex]a=\frac{7+14}{2} 5\\7+14=21\\\frac{21}{2} =10.5\\10.5*5=52.5[/tex]

so the area of the trapezoid is 52.5 ft²

Now we just add the two areas together

52.5+168=220.5

so the total area of the figure is 220.5 ft²

Answer:

a) 77    b)B

Step-by-step explanation:

letterF is the same as 77 meaning that X will be the same as letterF cause the are vertically opposite angles.

I just did the question on math watch.

The measure of the angle ∠BFH that is 'x' will be 77 degrees. Then the correct option is B.

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 °.

Alternate angle - If two lines are parallel then the third line will make z -an angle and z-angles equal angles with the parallel lines.

Line AD is parallel to line EH. And the line CG is the transversal line to line AD and EH.

The angle ∠FAB is congruent with the angle ∠BFH. Because they are alternate angles. Then we have

∠BFH = ∠FAB

x = 77°

The measure of the angle ∠BFH that is 'x' will be 77 degrees. Then the correct option is B.

Answer:

t = 35.13

Step-by-step explanation:

Simplifying

62.52 = 27.39 + t

Solving

62.52 = 27.39 + t

Solving for variable 't'.

Move all terms containing t to the left, all other terms to the right.

Add '-1t' to each side of the equation.

62.52 + -1t = 27.39 + t + -1t

Combine like terms: t + -1t = 0

62.52 + -1t = 27.39 + 0

62.52 + -1t = 27.39

Add '-62.52' to each side of the equation.

62.52 + -62.52 + -1t = 27.39 + -62.52

Combine like terms: 62.52 + -62.52 = 0.00

0.00 + -1t = 27.39 + -62.52

-1t = 27.39 + -62.52

Combine like terms: 27.39 + -62.52 = -35.13

-1t = -35.13

Divide each side by '-1'.

t = 35.13

Simplifying

t = 35.13

4       -1

Step-by-step explanation:

5 + 1 = 6

7 + 1 = 8

1 + 1 = 2

-2 + 1 = -1

simply divide the numerator and denominator by 9 (the GCF). So, 927 = 9÷927÷9 = 13. Thus, 927 is equivalent to 13 in the reduced form.

Answer:

It's simplified form is 1:3

Step-by-step explanation:

1st step: Convert them into fraction i.e.

[tex] \frac{9}{27} [/tex]

2nd step: Now check for their HCF i.e 9 so,

[tex] \frac{9 \div 9}{27 \div 9} [/tex]

And divide it with both the numerator and denominator and the result is,

[tex] \frac{1}{3} [/tex]

3rd step: Now convert them into ratio i.e

1:3

Hence, 9:27 simplified format is 1:3 (Ans)

Answer:4

Step-by-step explanation:

Answer:

Los números decimales son una combinación de números enteros y números que se encuentran entre los números enteros. A veces es importante poder comparar decimales para saber cuál es mayor. Por ejemplo, si alguien corrió los 100 metros planos en 10.57 segundos, y alguien más los corrió en 10.67 segundos, puedes comparar los decimales para determinar qué tiempo es más rápido. Saber cómo comparar decimales requiere el entendimiento del valor de posición decimal, y es similar a comprar números enteros.

Cuando trabajamos con decimales, hay veces que no se necesita un número preciso. En tal caso, es útil redondear números decimales. Por ejemplo, si la bomba de una gasolinera muestra que llenaste el tanque del carro de un amigo con 16.478 galones de gasolina, podrías querer redondear el número y decirle a tu amigo que le pusiste 16.5 galones.

Step-by-step explanation:

Otra forma de comparar decimales es comparar los dígitos en cada número, empezando con el lugar de posición mayor, que es el de la izquierda. Cuando un dígito en un número decimal es mayor que el dígito correspondiente en el otro número, entonces ése número decimal es mayor.

Por ejemplo, primero compara los dígitos de las décimas. Si son iguales, continúa con el lugar de las centésimas. Si esos dígitos no son iguales, el decimal con el dígito mayor es el número decimal mayor. Observa cómo se hace esto en los ejemplos siguientes.

Answer:

6 years old

Step-by-step explanation:

Given

[tex]f(t) = 200(1 -0.956e^{-0.18t})[/tex]

Required

Find t when f(t) = 140cm

Substitute f(t) = 140cm

[tex]140 = 200(1 -0.956e^{-0.18t})[/tex]

Divide both sides by 200

[tex]0.7 = 1 -0.956e^{-0.18t}[/tex]

Collect like terms

[tex]0.956e^{-0.18t} = 1 -0.7[/tex]

[tex]0.956e^{-0.18t} = 0.3[/tex]

Solve for t

[tex]e^{-0.18t} = 0.3/0.956[/tex]

[tex]e^{-0.18t} = 0.31381[/tex]

Take natural logarithm of both sides

[tex]ln(e^{-0.18t}) = ln(0.31381)[/tex]

[tex]-0.18tln(e) = ln(0.31381)[/tex]

[tex]-0.18t*1 = ln(0.31381)[/tex]

[tex]-0.18t = -1.159[/tex]

Solve for t

[tex]t = (-1.159)/(-0.18)[/tex]

[tex]t = 6.43[/tex]

[tex]t \approx 6[/tex]

Answer:

Yes (2,3) is a solution to this system of equations

Step-by-step explanation:

(x,y) (2,3) so x=2 y=3

3=3

3=2+1

Equations are true so it's a solution

Answer:

(b) and (c) are true

Step-by-step explanation:

Given

Function A and B

First, calculate the slope of A

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{24 - -21}{8- -7}[/tex]

[tex]m = \frac{45}{15}[/tex]

[tex]m =3[/tex]

The equation of function A is:

[tex]y = m(x - x_1) + y_1[/tex]

[tex]y = 3(x - 8) + 24[/tex]

[tex]y = 3x - 24 + 24[/tex]

[tex]y = 3x[/tex]

The general form of a function is:

[tex]y = mx + b[/tex]

Where [tex]m = slope[/tex] and [tex]b = y\ intercept.[/tex]

This implies that:

[tex]Slope = 3[/tex]

[tex]Y\ intercept = 0[/tex]

For function B:

[tex]y = 4x - 3[/tex]

[tex]Slope = 4[/tex]

[tex]Y\ intercept = -3[/tex]

By comparison:

(b) and (c) are true
