Hello!

$\frac{2}{3}$ x 12 = 8.

It will take her 8 days to weave 12 baskets.

Enjoy.

One day = 2/3 basket.

Number of days needed to complete 12 baskets:

$12 \div \dfrac{2}{3}$

$= 12 \times \dfrac{3}{2}$

$= 18 \text { days}$

To find an object’s density (D), first measure its mass (m) and volume (V). Then use the following equation:

Mariana [72]

Answer:

C. 20 cm^3

Step-by-step explanation:

Using the equation D=m/v, you would plug in the given mass (227 g) into m and the given density of lead (11.35 g/cm^3). Solving for v=m/D, we find the answer to be 20 cm^3.

Also, you could cancel out all the answers except C because it is the only one in units of volume (1 cm^3 = 1 mL).

Show that the angles of an equalateral triangle are 60°each

topjm [15]

Answer:

For an equilateral triangle, we know that all 3 sides of the triangle are equal. Accordingly, all the 3 sides of the equilateral triangle hold equal angles.

Since, we know, that the sum of all angles of any triangle be 180° .

Let each angle be a.

Thus,

Hence, we can show that all the 3 angles of an equilateral triangle hold equal angles; i.e. 60°.

Answer:

Step-by-step explanation:

<em>hey there,</em>

< Here's how you do subtraction in fractions!

Make sure you find a least common denominator. Here, it's given to you to be 15. Usually, you can just multiply the two denominators but then it would be quite large at times, so you kind of just have to guess.

How did they go from $\frac{4}{5} x-\frac{1}{3} x$ to $\frac{?}{15} x$ ?

Well, they used a least common denominator. 5 was multiplied by 3 to create 15, and 3 was multiplied by 5. But when you multiply the bottoms, you have to multiply the tops of the fraction too (the numerators).

So 4/5x was multiplied by 3. Denominator turned out to be 15, and now the top is 4x3 = 12. So the fraction is 12/15.

1/3x, on the other hand, was multiplied by 5. Denominator was also 15 so they're the same, and top is 1x5 = 5. So the fraction is 5/15.

Now, let's put them together.

$\frac{12}{15}x-\frac{5}{15} x$

When subtracting x, the x just stays there, so if it was 10x-4x, the answer would've been 6x. So now let's subtract!

12-5 = 7, and the denominator stays the same.

The answer is $\frac{7}{15} x$ . So the numerator, or answer to your question, would be 7.

T(h) = - A - B * cos((pi*h)/12) Where T is the temperature in degrees Fahrenheit and h is the number of hours from midnight (0 &

kondor19780726 [428]

The value of A and B is 5 , 10 ;The average temperature for first ten hours is -7.466 degree F ; an expression for the rate that the temperature is changing with respect to h ; dt/dh = +B sin ((pi*h)/12)

<h3>What is a Function ?</h3>

A function is a mathematical statement used to correlate two variables.

The function given is

T(h) = - A - B * cos((pi*h)/12)

T is the temperature in degrees Fahrenheit and

h is the number of hours from midnight (0 <= h <= 24)

a. The initial temperature at midnight was - 15 degrees * F and

at Noon of New Year's Day it was 5 degrees * F

At midnight h = 0

T(h) = -15 degrees F

-15 = -A-B* cos 0

-15 = -A-B

A+B = 15------------------- (1)

At noon , h = 12 , T(h)= 5

- A - B* cos(pi) = 5

-A - B (-1) = 5

B -A = 5 ----------------------- (2)

Solving equation 1 and 2

2B = 20

B = 10

A = 5

The value of A and B is 5 , 10

The average temperature for first ten hours is -7.466 degree F

Find an expression for the rate that the temperature is changing with respect to h

dt/dh = +B sin ((pi*h)/12)
