What is the answer to 7=100z

1 answer:

6 0

Divide both sides of the equation by the same term
7/100=100z/100
Simplify
Cancel the terms that are in both The numerator and the denominator
Move the variable to the left
Z=7/100

6p + 1m = $9<br><br> 4p + 2m = $8

Monica [59]

You can multiply 6p + m = 9 by -2 so you gonna have -12p - 2m = -18 then you can say : -12p - 2m = -18 ⇒ -8p = -10 ⇒ p = 10/8 ⇒ p = 1.25
4p + 2m = 8
so now you can find the m : 6 * 1.25 + m = 9 ⇒ 7.5 + m = 9 ⇒ m = 9 - 7.5 ⇒ m= 1.5 :)))
i hope this is helpful

Step-by-step explanation:

<h3>understanding the question</h3>

The question is asking you to express the temperature at 5 pm as a pair of graph coordinates.

Doing this requires that you ...

read from the graph the temperature at 2 pm
read from the graph the temperature at 8 pm
figure the temperature halfway between those values
express the 5 pm temperature as an ordered pair (hours, °C)

<h3>reading the graph</h3>

The description of the graph tells you the horizontal scale is hours after noon, so the temperature at 2 pm will be a point on the graph with an x-coordinate of 2. That point is (2, 7), indicating the temperature at 2 pm is 7 °C.

Likewise, the temperature at 8 pm is shown as the point on the graph with x-coordinate 8. That point is (8, -3), indicating a temperature of -3°C at 8 pm.

<h3>halfway temperature</h3>

The temperature halfway between those values (7 °C and -3 °C) can be found several ways. Perhaps the easiest is to average the values:

(7 +(-3))/2 = 4/2 = 2

The temperature at 5 pm is 2 °C.

<h3>coordinates</h3>

Coordinates on the graph are ordered pairs of the form (x, y) = (hours, °C). The time 5 pm is 5 hours after noon, so the x-coordinate is 5. The temperature at 5 pm is halfway between the temperatures at 2 and 8 pm, which we have computed to be 2 °C, so the y-coordinate is 2.

The coordinates that represent the temperature at 5 pm are ...

Evaluate the expression.

gizmo_the_mogwai [7]

Answer:

Step-by-step explanation:

To solve this question you will need to use BEDMAS which is the order of which numbers you have to solve first. In this case you need to solve the brackets first, then the exponent, and then lastly the addition.

3^3 + 3(4 + 1/3)

= 3^3 + 3(13/3)

= 27 + 3 x 13/3

= 27 + 13

= 40

What is the relationship between the sine of an angle and cosine of the other acute angle in the same triangle? Will this be tru

elixir [45]

Consider in triangle as given below:

sin(A) = opposite/hypotenuse = BC/AC
cos(B) = adjacent/hypotenuse = BC/AC

<span>Now, both of them have the same hypotenuse and both will be equal. As you have seen already both the values are same.
</span>Thus, the <span>relationship between the sine of an angle and cosine of the other acute angle in the same triangle is shown below. And this ill this be true every time.</span>
