Solve for z. 7z+ 4 – 9z = 8 z = [?]​

Answers

Answer 1

Answer:

z = -2

Step-by-step explanation:

7z + 4 - 9z = 8 (The first step is to combine like terms, so 7z -9z = -2z)

-2z + 4 = 8 (Subtract 4 on each side)

-2z = 4 (Divide each side by -2)

z = -2

You can plug -2 back in to check, and you get:

7(-2) + 4 -9(-2) = 8

-14 + 4 + 18 = 8

8 = 8

Hopefully, this helped. Good luck!

Answer 2

Answer:

z=-2

Step-by-step explanation:

7z+4-9z=8

7z-9z=8-4

-2z=4 divide by-2

z=-2

un campo de futbol tiene 100m de largo y 60m de ancho¿ Cuales son la longitud y la anchura del campo?

Answers

Answer:

328 pies de largo

196.8 pies de ancho

Step-by-step explanation:

Ya que las medidas dadas estan en metros, podemos usar esas medidas para calcular la longitud y anchura en pies.

100 metros de largo.

60 metros de ancho.

Si sabemos que 1m es igual a 3,28 pies, simplemente tenemos que multiplicar las medidas en metros por 3.28 y nos va dar la medida del campo en pies.

100 * 3.28 = 328 pies de largo

60 * 3.28 = 196.8 pies de ancho

A person places $73700 in an investment account earning an annual rate of 5.5%, compounded continuously . Using the formula V = P * e ^ (rt) , where V is the value of the account in t years, P is the principal initially invested , e is the base of a natural logarithm, and r is the rate of interest, determine amount of money, to the nearest cent , in the account after 11 years .

Answers

Answer:

The amount in the account after 11 years is $134,963.29

Step-by-step explanation:

Here, we want to determine the amount in the account after 11 years

What we have to do here is to substitute P for the amount invested which is $73,700

r is the rate given as 5.5% = 5.5/100 = 0.055

t is the time given as 12 years

substituting these values, we have;

V = 73,700 * e^(12* 0.055)

V = $134,963.29

a football team gains 9 1/2 yards on their first play then lose 10 yards for a penalty they lose 5 yards and then gain 7 yards on the next two plays what is the teams overall gain or loss and did rhey make a first down (10+ yards)?

Answers

Answer: No

Step-by-step explanation: Because if the team lost 10 yards from 9 1/2 then they would be negative yards if they lose 5 yards they will have 5 1/2 and if they gain 7 yards their total will be 1.5 so they never made it to 10+ yards.

The equation that matches the function shown is option;

C. [tex]y = sin\left (\dfrac{1}{2} \cdot x\right)[/tex]

Step-by-step explanation:

The given graph of the function is a sinusoidal graph

The values of 'x' and 'y' coordinates at the maximum, x-intercept and minimum points are given as follows;

x, [tex]{}[/tex]      y

0    [tex]{}[/tex]   0

π [tex]{}[/tex]       1

2·π   [tex]{}[/tex] 0

3·π [tex]{}[/tex]    -1

4·π [tex]{}[/tex]    0

We note that sin(π/2) = 1, sin(π) = 0 sin(3·π/2) = -1, and sin(4·π/2) = sin(2·π) = 0

Therefore;

y = the sine of half the x-value

A farmer planted corn in a square field. One side of the field measures 37 yards. What is the area of the cornfield

Answers

37 times 37 which is 1369

Answer:

1,369 cm^2

Step-by-step explanation:

A square is a two-dimensional shape with four right angles and four equal sides.

This means each and every side is equal.

In this case, every side is 37 yards.

To find the area of a square, simply multiply a length of a side by itself.

Like this,

37⋅37 = 1,369.

Therefore, the area of the cornfield is 1,369 yards cm^2.
