1. If 3X + Y =P and X+Y=Q, what is X in terms of P and Q?

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s).

sergiy2304 [10]

Answer:

The measure of angle θ is 7π/6. The measure of its reference angle is 210°

and sin θ is -1/2.

Step-by-step explanation:

The correct question is:

The measure of angle θ is 7π/6. The measure of its reference angle is ___

and sin θ is ___

180° is equivalent to π radians. To transform 7π/6 radians to degrees, we have to use the following proportion:

180° / π radians = x° / (7π/6 radians)

x = (180/π) * (7π/6 radians)

x = 210°

And sin(210°) = -1/2

Use the commutative property of multiplication to identify which expression is equivalent to 6(2)(x).

11Alexandr11 [23.1K]

The commutative property is when you change the order but not the answer. To better understand what they are asking you, let's let x=1- 6 * 2 * 1=12; Answer A wouldn't be right because there are no 6,2, or x's. Remember you just change the ORDER not the GROUPING so Answer B is wrong too. Now Answer C and Answer D are left. Now you just need to look at the signs. 6(2) just means 6 TIMES 2 so pick the option with multiplication. So your answer is C. Hope I helped!

a crowbar of 2cm is used to lift an object if 800N. if the effort arm is 260cm. calculate the effort applied.

Gelneren [198K]

Answer:

solution:Here

Given,

Load=800 N

Load distance=2cm

Effort distance=260cm

Effort applied=?

We know that,

Load × Load distance = Effort × Effort distance

or, 800×2 = e × 260

or,1600 = 260e

or,e = 1600/260

Thus, e = 6.15 N

Hence, The effort applied = 6.15 N

Hope this answer helped you..

A cake has circumference of 25 1/7 inches. What is the area of the cake? Use 22/7 to approximate π. Round to the nearest hundred

choli [55]

Answer:

50.29 in^2

Step-by-step explanation:

From the circumference we need to find the radius.

Since C = 2*pi*r, r = C / (2*pi).

Here, with C = 25 1/7 in, r = (25 1/7 in) / [ 2(22/7) ], or r = 4 in

The area of the cake is A = pi*r^2, or (here) A = (22/7)(4 in)^2 = 50.29 in^2

Find the slope of the line passing through the points given below or state that the slope is undefined. Then indicate whether th

Alex17521 [72]

Answer:

The slope is 3 and the line is rising.

Step-by-step explanation:

To find the slope m of a line given two points (x₁, y₁) and (x₂,y₂) we can use the formula:

m = (y₂-y₁) / (x₂ - x₁)

In this problem we have the points (6,2) and (7,5), substituting these values in the formula we get:

m = (5 - 2) / (7 - 6) = 3/1 = 3

Therefore, the slope is 3.

Given that the slope is positive we can conclude that the line through the points rises.
