Answer:

Step-by-step explanation:

PEMDAS

1) Solve what is in the parenthesis going from left to right. (4-9= -5)

2) Then, multiply that value by what's in the second parenthesis (-5)(-6)=30

3) Lastly, consider anything not in parenthesis. Subtract the 1 since there is a minus sign in front

(4-9)(-6)-1=

(-5)(-6)-1=

30-1=

What the perimeter of 2m 10cm and 45cm of a rectangle

telo118 [61]

You only told us the length of 3 sides, and from those 3,
we can already see that it's not a rectangle. (If you take
any 3 sides of a rectangle, two of them must be the same
length.)

So we have no way to tell the length of the 4th side, or to
add up the lengths of all 4 sides to get the perimeter.
It could be many different things.

The only thing we know for sure is that the perimeter must be
more than 2.55 meters. (That's the sum of the 3 sides you gave us.)

QUICK PLEASE !!!!!

Leni [432]

Answer:

Step-by-step explanation:

The slope-intercept form of an equation of a line:

$y=mx+b$

m - slope

b - y-intercept

The formula of a slope:

$m=\dfrac{y_2-y_1}{x_2-x_1}$

==============================================

From the table we have :

x = 1 → y = 6

x = 2 → y = 9

x = 3 → y = 12

x = 4 → y = 15

Calculate the slope (choice any two pairs, and calculate the slope):

(1, 6), (2, 9)

$m=\dfrac{9-6}{2-1}=\dfrac{3}{1}=3$

We have the equation:

$y=3x+b$

Put the coordinates of the point (1, 6) to the equation, and solve it for b:

$6=3(1)+b$

$6=3+b$ <em>subtract 3 from both sides</em>

$3=b\to b=3$

Finally:

$y=3x+3$

serious [3.7K]

Answer:

Sara expect the better grade for Math class.

Step-by-step explanation:

Consider the provided information.

On the Math exam, the mean was µ = 30 with s = 5, and Sarah had a score of X = 45.

Z score for Math: $Z=\frac{x-\mu}{s}$

$Z=\frac{45-30}{5}$

$Z=\frac{15}{5}$

$Z=3$

On the Spanish exam, the mean was µ = 60 with s = 8 and Sarah had a score of X = 68.

Z score for Spanish: $Z=\frac{x-\mu}{s}$

$Z=\frac{68-60}{8}$

$Z=\frac{8}{8}$

$Z=1$

On the English exam, the mean was µ = 70 with s = 8 and Sarah had a score of X = 70.

Z score for English: $Z=\frac{x-\mu}{s}$

$Z=\frac{70-70}{8}$

$Z=0$

We can observe that Z score of Math is greater than Spanish and English.

Which means that Sarah did the best in her Math exam.

Hence, Sara expect the better grade for Math class.

which of the following is the most appropriate unit to describe the time you can drive a car based on the amount of gas

Sunny_sXe [5.5K]

If you're describing a time, then it has to have a unit of time. We have no idea how much gas you're talking about, so second, minute, and hour are all possibilities.
