Step-by-step explanation: you have to make the Denominator equal for all of them In order to be able to compare. So if you make the denominator equal to 36 you then have to multiply the numerator by the same number you did for the denominator. Once doing that you will find that 24/36 < 27/36 < 28/36

Imagine looking for a certain angle whose cosine is positive and whose sine is negative.

Part 1: Name the two quadrants in which cosine is positive.

Part 2: Name the quadrants in which sine is negative.

Part 3: Use the information in parts a and b to identify the quadrant in which cosine is positive and sine is negative.

Part 4: Write down one angle, in degrees, that has a negative sine and a positive cosine.

Part 5: Using your calculator, confirm your choice by writing the cosine of your angle and the sine of your angle below.

Answers

The two quadrants in which cosine is positive are the first quadrant (Q1) and the fourth quadrant (Q4).

How to explain the information

Part 2: The quadrants in which sine is negative are the third quadrant (Q3) and the fourth quadrant (Q4).

Part 3: Based on the information from parts 1 and 2, the quadrant in which cosine is positive and sine is negative is the fourth quadrant (Q4).

Part 4: One angle that has a negative sine and a positive cosine in the fourth quadrant is 135 degrees (or 3π/4 radians).

Part 5: Using a calculator, we can confirm the values of cosine and sine for 135 degrees:

Cosine of 135 degrees: cos(135°) ≈ -0.7071 (rounded to four decimal places)

Sine of 135 degrees: sin(135°) ≈ -0.7071 (rounded to four decimal places)

Answer:

m∠A = 130

Step-by-step explanation:

Here, In a given figure

m∠A = 2x - 30°

Now, we know that the sum of all angle is 180° on a straight line

So,

2x - 30° + 50° = 180°

2x + 20° = 180°

2x = 180° - 20°

2x = 160°

x = 160° ÷ 2

x = 80°

Here, we get the value of x is 80°

Now,

m∠A = 2x - 30°

m∠A = 2(80°) - 30°

m∠A = 160° - 30°

m∠A = 130

Thus, m∠A = 130

Answer:

A) By using the Pythagorean Theorem, we will see that [tex]8^2 + 15^2 = 17^2[/tex]. If we simplify it, we will find that the hypotenuse of Δ[tex]ABC = 17[/tex]

B) approximately [tex]18.79[/tex]

Step-by-step explanation:

A) In all honesty, you don't really need to look at ΔACD at all for this one. Just use the Pythagorean Theorem (like previously stated) and solve!

***Pythagorean Theorem is [tex]leg^2 + leg^2 = hypotenuse^2[/tex]

B) Here, you can also use the Pythagorean Theorem! However this time, the equation will be, [tex]8^2 + 17^2 = AD[/tex].

[tex]8^2 + 17^2 = 64 +289[/tex][tex]64 + 289 = 385[/tex][tex]\sqrt{385} \\[/tex] ≈ [tex]18.79[/tex]

In the formulae below, make x the subject:
1. a) P = 2mx

Answers

Answer:

x = P/2m

Step-by-step explanation:

x is the subject of the formula, and we can express it as: x = P / (2m)

How make x the subject

To make x the subject in the formula P = 2mx, we can rearrange the equation to isolate x on one side.

Starting with the equation:

P = 2mx

To solve for x, divide both sides of the equation by 2m:

P / (2m) = (2mx) / (2m)

This simplifies to:

P / (2m) = x

Therefore, x is the subject of the formula, and we can express it as:

x = P / (2m)

You are cutting pieces of fabric for a craft project. You need three pieces that measure 6 2/3 inches, 4 1/2inches, and 3 5/8inches.
What is the total length of fabric that you need ?

Answers

Answer:

You need 14 19/24 inches of fabric

Step-by-step explanation:

We'll need a common denominator between 2/3, 1/2, and 5/8. 24 is the least (lowest) common denominator.

3 x 8 = 24, so we multiply the numerator and denominator by 8 and 6 2/3 becomes 6 16/24ths

2 x 12 = 24, so we multiply the numerator and denominator by 12, and 4 1/2 becomes 4 12/24

8 x 3 = 24, so we multiply the numerator and denominator by 3, and 3 5/8 becomes 3 15/24.

Now we are adding 6 16/24 + 4 12/24 + 3 15/24

6 16/24 + 4 12/24 + 3 15/24 = 6 + 4 + 3 + 16/24 + 12/24 + 15/24

= 13 + 43/24 = 14 19/24

3b/7 -1 = 5

Answers

Answer:

b = 14

Step-by-step explanation:

The required solution to the equation 3b/7 - 1 = 5 is b = 14.

What is simplification?

Simplification involves directions of arithmetic and algebra to remove disproportionate terms, factors, or operations from an expression. The goal is to obtain an expression that is easier to work with, manipulate, or solve. For example, simplifying an algebraic expression might involve combining like terms, factoring, or using the distributive property

Here,
To solve for b, we need to isolate b on one side of the equation.

First, we add 1 to both sides of the equation to get:

3b/7 = 5 + 1

Simplifying the right-hand side:

3b/7 = 6

Next, we multiply both sides by 7/3:

(7/3) * (3b/7) = (7/3) * 6

Simplifying:

b = 14

Therefore, the solution to the equation 3b/7 - 1 = 5 is b = 14.
