I need help solving for x i have no clue what to do arcsin(7x-pi)=1/10

1 answer:

5 0

I will assume this is in radians as pi is in the equation...

sin(arcsin(7x-p)=sin(1/10)

7x-p=sin(1/10)

x=(sin(1/10)+p)/7

x≈0.463

See picture for problem!

Answer: Length = 36m

Step-by-step explanation:

P = w * 2 + l * 2

Width = w

Length = w + 5

P = w + w + (w + 5) + (w + 5)

P = 4w + 10

134 = 4w + 10

-10

124 = 4w

31 = w

So, the width is 31m.

Length = 31 + 5

31 + 5 = 36

Therefore, the length is 36m

You can also check this: P = w * 2 + l * 2

31 * 2 = 62

36 * 2 = 72

72 + 62 = 134

When Jean was asked to say what the 3 in the fraction 2

JulijaS [17]

Fractions are quotients of two integers

A better way to say what the 3 in 2/3 represents is that, 3 is the denominator

<h3>How to determine what 3 represents</h3>

The fraction is given as: 2/3

A fraction is represented as: Numerator/ Denominator

By comparison;

Numerator = 2
Denominator = 3

Hence, a better way to say what the 3 in 2/3 represents is that, 3 is the denominator

chef ollie has a community garden.she uses 2/6 of the farmland to grow beets and 1/6 of the farmland to grow kale. how much of t

Lorico [155]

Answer:

1/2 of farm land left.

Step-by-step explanation:

Ok so we know that Chef Ollie has a community garden. And that she uses $\frac{2}{6}$ of the farmland to grow beets. The denominator 6 lets you know immediately that the land is divided into equal 6 pieces. We also know that Chef Ollie uses another $\frac{1}{6}$ of the farmland to grow kale.

Because the we need to find out how much land Chef Ollie has left, we need to subtract the amount she used from the whole. Before we can do that we must add up the total amount of used land, and since the denominators are the same we can directly add and subtract with having to change the denominator.

Step 1: Write down important numbers.

$\frac{2}{6}$ , $\frac{1}{6}$ ,

Step 2: Add those numbers together.

$\frac{2}{6} + \frac{1}{6} = \frac{3}{6}$ or $\frac{1}{2}$

Step 3: Write an expression/equation.

$\frac{6}{6} - \frac{3}{6} \\or\\1 - \frac{1}{2}$

Step 4: Solve

= $\frac{3}{6}\\or\\\frac{1}{2}$

(can be written both ways)

And you get your answer: After Chef Ollie has used $\frac{2}{6}$ to grow beets and $\frac{1}{6}$ to grow kale, she has $\frac{1}{2}$ of her farmland left untouched.

To represent this you could draw a circle divided in 6 pieces and shade 3 of them, or simply draw a circle and shade half. As well as drawing a rectangle and dividing it into 6 pieces, shading 3, or draw a rectangle, and shade half.

You are welcome ;) .
