A circular sign is precisely designed to have an area of 50.24 square inches. What is the sign's circumference?
choli [55]

Step-by-step explanation:

First of all we need to know the formula for the circumference which is: c=2\pi r

We don't have the radius. What we only have is the area; therefore, we must use the area formula and extract the radius from it.

The formula for the area is: A=\pi r^2 Solve for r;

r^2=\frac{A}{\pi}\\ r=\sqrt[]{\frac{A}{\pi} }

r=\sqrt[]{\frac{50.24inch^2}{3.14} }

r=\sqrt[]{16inch^2}\\ r=4inch

Now that we've found the radius, we simply plug it into the circumference formula.

C=2\pi r\\C=2(3.14)(4)\\C=25.12inch

The growth rate of the sunflower from day 14 to day
nata0808 [166]

Option B) h = 4.5t – 27 is the equation of the straight line that best models the height h, in centimeters, of the sunflower t days after it begins to grow.

                     

From the above graph we can see that from day 14 to day 35 , it is a straight line.

And equation of a straight line is   y = mx + c  or   y – y1 = m(x – x1)

                               Where, m =slope of the line

                                             c = intercept

the equation can be rewritten as  h – h1  = m(t – t1)                    (1)

So, to find the equation of line , first we will calculate the slope of the line.

To find the slope : m = (h2 – h1 ) / (t2 – t1)                     (2)

From the graph and the table given, the coordinates (t1 , h1 ) and ( t2 , h2 ) are (14 , 36.6) and (35, 131) respectively.

Putting these values in equation (2), we get

                 m = (131 – 36.6)/(35 – 14)

                 m =  94.4/21

                 m  = 4.5

now to find the equation of line we put the values in equation (1), we get

h – 36.6 = 4.5(t – 14)

h – 36.6 = 4.5t – 63

h = 4.5t -63 + 36.6

h = 4.5t -27

Hence the equation of the line is ,   option B) h = 4.5t -27

*IGNORE THE ANSWERS*<br> This is 2nd grade math. I forgot how to solve these equations. Help:)
Mazyrski [523]

Answer:

a. 14

b. 7

Step-by-step explanation:

a. First we must add all the animals together,

Total Animals:

Birds: 6

Fish: 5

Mammals: 11

Reptiles: 3

Therefore our equation is:

6 + 5 + 11 +3 = 25.

Now, we must subtract by the number of mammals:

25 - 11 = 14

So our answer for a. is 14!

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

b. So for this problem we must compute mammals + fish and than birds + reptiles. After we figure that out we must subtract them!

Mammals + Fish =

11 + 5 =

16

Next,

Birds + Reptiles =

6 + 3 =

9

Now, let us subtract them,

16 - 9 =

7

So our answer for b. is 7 more animals!

Answer:

∠MNP is your answer

Step-by-step explanation:

Note the angle and the order it is said. It is ∠ABC, which means the double line side, one curve line angle, and then triple line side.

Now look at the second triangle, the same double line side (NM), one curve line angle (∠N), and triple line side (NP)

Put them together: ∠MNP is your answer
