Answer:

c. 1

Step-by-step explanation:

Remember PEMDAS.

Parenthesis. Exponents. Multiplication. Division. Adition and Substraction. As a guide to help you remember the order.

But keep in mind one thing, the MD looks as if multiplication has a priority over division, yet it is not, the M and the D have the same weight to them, so depending on where they are in the operation, you have to do them simultaneously, also, you always read the equation from left to right, so we have as a result:

[27-32]/9*2

-5/9*2 Now, from left to right: -0.56*2=-1.11

None of the answers are -1.11, but the closest one is C. 1

Melinda walked 9/10 of a mile for 5 days. What was the total distance in miles, she walked 5 days?
Charra [1.4K]
Multiply how far she walked each day by the number of days.

= 9/10 mile * 5 days
multiply numerator (top) by 5

= (9*5)/10
= 45/10

reduce by 5
= 9/2

convert to mixed number (2 goes into 9 four times with a remainder of one)
= 4 1/2 miles


ANSWER: She walked 4 1/2 miles in 5 days.

Hope this helps! :) If you found it helpful, please mark me brainliest.

Write an equation of the line in slope-intercept form.
Tasya [4]

Answer:

y = x + 4

Step-by-step explanation:

From point (-1, 3) to point (0, 4), go up 1 (rise = 1) and go right 1 (run = 1).

slope = m = rise/run = 1/1 = 1

The y-intercept is b = 4

y = mx + b

y = x + 4

babunello [35]

To find the slope, you use the slope formula (m):

m=\frac{y_2-y_1}{x_2-x_1}    and plug in the two points

(-3, 4) = (x₁, y₁)

(2, -1) = (x₂, y₂)

m=\frac{y_2-y_1}{x_2-x_1}

m=\frac{-1-4}{2-(-3)}       [two negatives cancel each other out and become positive]

m=\frac{-1-4}{2+3}

m=\frac{-5}{5}

m = -1        The slope is -1

Simplify the trigonometric expression. Is this the correct answer?
horrorfan [7]

Answer:

\boxed{\tan \theta}

Step-by-step explanation:

\dfrac{\tan \theta }{\sin^{2} \theta + \cos^{2} \theta}

Use the trigonometric identity

\sin^{2}\theta + \cos^{2}\theta = 1

Then,

\dfrac{\tan \theta }{\sin^{2} \theta + \cos^{2} \theta} = \dfrac{\tan \theta }{1} = \boxed{\tan \theta}
