Answer:

168 feet

Step-by-step explanation:

area of trapezoid = length (a)+ breadth(b) / 2 height

Step-by-step explanation:

Since 64 = 32 * 2 and 32 = 32 * 1,

64 + 32 = 32(2 + 1).

16(4 + 2) is wrong as 4 and 2 have a GCF of 2.

8(8 + 4) is wrong as 8 and 4 have a GCF of 4.

32(2) + 1 is the wrong application of the distributive property.

Answer:

64+32=32(2+1) is greatest common factor

C. Protractor

Answer:

A

Step-by-step explanation:

A compass is for directions.

Answer:

The answer could be anything, but if it's an arithmetical sequence, then it's 14.

Step-by-step explanation:

I'm assuming that the added numbers always stay the same, meaning it's linear. If you add 5 to 9, you get 14. If you add 5 again, you get 19. Another way of doing this is (19-9)/2 = 5, then 9+5=14.

Answer:

yes the ordered pair is a solution

Step-by-step explanation:

(x, y) = (0,0)

y < -x + 3

0 < - (0) + 3  

0 < 3

true, ordered pair is a solution

Answer:

La situación está representada por el siguiente sistema:

[tex]y = 20+2\cdot x[/tex]

[tex]y \ge 50[/tex]

Donde:

[tex]x[/tex] - Cantidad de rosas vendidas semanalmente.

[tex]y[/tex] - Ganancia semanal, medida en dólares.

Step-by-step explanation:

De acuerdo con el enunciado, Nita gana una cantidad fija cada semana por pasear al perro de su vecino, con un monto de $ 20, mientras que gana en función de la cantidad de rosas a vender, con un valor unitario de $ 2. Si ella desea ganar al menos $ 50, por tanto, se requiere construir el siguiente sistema, conformado por una ecuación y una inecuación:

[tex]y = 20+2\cdot x[/tex] (1)

[tex]y \ge 50[/tex] (2)

Donde:

[tex]x[/tex] - Cantidad de rosas vendidas semanalmente.

[tex]y[/tex] - Ganancia semanal, medida en dólares.

Answer:

about $26.00

Step-by-step explanation:

$25/100 = 0.25 for 1%

1% times 4.1 = 1.025 in sales tax

plus 25 equals 26.025

round to the nearest cent = $26.00

Answer:

The scale factor of the dilation is 3 ⇒ A

Step-by-step explanation:

In the given figure

∵ EFGH is a polygon

∵ E = (-2, 1), H = (-2, -1)

∵ EH is a vertical side

→ By using the 2nd rule above

∴ The length of EH = 1 - (-1) = 1 + 1

∴ The length of EH = 2

∵ E'F'G'H' is its image after dilation by scale factor k

∵ E' = (-2, 5), and H' = (-2, -1)

∵ E'H' is a vertical side

∴ The length of E'H' = 5 - (-1) = 5 + 1

∴ The length of E'H' = 6

→ By using the 1st rule above

∴  [tex]\frac{E'H'}{EH}[/tex] =  [tex]\frac{E'F'}{EF}[/tex] =  [tex]\frac{H'G'}{HG}[/tex] =  [tex]\frac{F'G'}{FG}[/tex] = k

∵  [tex]\frac{E'H'}{EH}[/tex] = k

∵ [tex]\frac{E'H'}{EH}[/tex] = [tex]\frac{6}{2}[/tex]

∴  [tex]\frac{E'H'}{EH}[/tex] = 3

∴ k = 3

∴ The scale factor of the dilation is 3

[tex]125a^{3}b^{2}[/tex]

Step-by-step explanation:

Answer:

The equation of a line that passes through the point (-1,5) and has a slope of -7 will be:

Step-by-step explanation:

The slope-intercept form of the line equation

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

where

Given

substituting m = -7 and the point (-1, 5) in the slope-intercept form of the line equation

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

5 = -7(-1) + b

5 = 7+b

b = 5-7

b = -2

Thus, the y-intercept is: b = -2

now substituting b = -2 and m = -7 in the slope-intercept form of the line equation

y = mx+b

y = -7x+(-2)

y = -7x-2

Therefore, the equation of a line that passes through the point (-1,5) and has a slope of -7 will be:

9514 1404 393
