Answer:

question 7 would be option 4 because its saying he has AT LEAST $5, which would mean he DOES have $5 or more. Which is why you would use the "more than or equal to" sign that was used in option 4.

question 8 would be option 1 because its a closed circle that includes the $5 and its going to the right.

3,524 a que numero decimal corresponde?

denpristay [2]

Answer:

3,524 corresponde al fraccionario $\frac{3524}{1000}$ .

Step-by-step explanation:

La coma está desplazada tres espacios (3 dìgitos) hacia la izquierda del observador, el número decimal tiene su equivalente forma fraccionaria, en donde el numerador son todos los dìgitos en series y el denominado tiene la forma 10ⁿ, donde n es la cantidad de espacios que ha sido desplazada la coma. Entonces, 3,524 tiene la siguiente expresión:

$3,524 = \frac{3524}{10^{3}}$

$3,524 = \frac{3524}{1000}$

3,524 corresponde al fraccionario $\frac{3524}{1000}$ .

Part A: If (7^2)^x=1, what is the value of x?<br> Part B: If (7^0)^x=1, what is the value of x?

Fantom [35]

A.
(7^2)^x = 1
(49)^x = 1
thus x = 0

B.
<span>(7^0)^x=1
(1)^x = 1
thus x can be any real number.

Determine the scale factor for the following points: (4, 2) to (16, 8)

hammer [34]

Answer:

The rule of dilation by a scale factor 4 is:

(x, y) → (4x, 4y)

P(4, 2) → (4x, 4y) = (4(4), 4(2)) = P'(16, 8)

Therefore, 4 will be the scale factor.

Step-by-step explanation:

Given the point

(4, 2)

As the image coordinates of (4, 2) are (16, 8) after the scale factor, we need to determine what could be the scale factor.

Let P(4, 2) is the original point, and P'(16, 8) is the image of the point P(4, 2).

It is clear that the coordinates of the image P'(16, 8) are 4 times the coordinates of the original point P(4, 2), which means the point P(4, 2) is dilated by a scale factor of 4.

Thus, the rule of dilation by a scale factor 4 is:

(x, y) → (4x, 4y)

P(4, 2) → (4x, 4y) = (4(4), 4(2)) = P'(16, 8)

Therefore, 4 will be the scale factor.

Answer:

Step-by-step explanation:

4 1/2 minutes = 4.5 minutes

2 / 4.5 = 0.44 laps per minute

4.5 / 2 = 2.25 minutes per lap

not sure which one ur looking for...but both are unit rates

Can I have some help with this question please?

inna [77]

Answer:

Step-by-step explanation:

the shape can be divided into two semi-circles of radius 5 cm and (11x10) cm rectangle

so,

area = (2 x 0.5x pi x 5x 5) + (11x10) = 188.5 cm sq
