Answer:

9 fruit tarts.

Step-by-step explanation:

What the question is essentially asking is: "If we split 6 whole cups into thirds of a cup, how many groups of 2 can we make out of those thirds?" Well, we have 3 thirds in every whole, so 6 wholes gives us 6 x 3 = 18 thirds. We can make 9 groups of 2 from 18, so our answer is 9 fruit tarts.

You invest $1000 in an account at 2.5% per year simple interest. How much will you have in the account after 4 years? Round to t

Liula [17]

Your final answer is $1100. (1000*2.5%) = 25, 25*4 = 100, 100+1000 = $1100.

Please help!

Answer:

$4 \sin( \frac{2}{7}x ) + 1$

Step-by-step explanation:

Let use the basic function of sin first.

Since the midline is 1 and the max point is 5, the amplitude is 4.

The midline is 1 since the midline is at 0,1.

Since we know the distance of the max and midline x values

We can multiply that by 4 to find our period.

$\frac{7\pi}{4} \times 4 = 7\pi$

Use the equation 2pi/b to find the b we would use in our equation.

$\frac{2\pi}{b} = 7\pi$

The answer is

$\frac{2}{7}$

so our equation is

$4 \sin( \frac{2}{7}x ) + 1$

What is the surface area of cone below Diameter AB=21 and distance from B to C =36

Vesnalui [34]

Answer:

1533.88261311522

Step-by-step explanation:

Let r be the radius of the (base/circle)

and L be the slant height of the cone

Formula ………………………………………………………………………………………………………

The surface area of a cone = the (curved/lateral) surface area + the base

$=\pi r^{2}\ \ \ +\ \ \ \pi Lr$

=========================================

$r=\frac{21}{2} =10.5$

L = BC = 36

$\text{surface area} =\pi \left( 10.5\right)^{2} +\pi \times 36\times \left( 10.5\right)$

$=346.360590058275 + 1187.52202305694$

$=1533.88261311522$

State 7m to 250cm as a ratio in its lowest terms

madam [21]

First you have to convert the numbers to the same units. Either m to cm or cm to m.
To go from meters to centimeters you multiply the number by 100.
7*100=700cm
Now you have 700cm/250cm. This needs simplified
I divided each number by 50 to get 14 and 5
14cm/5cm or 14cm:5cm
