A pitcher struck out 11 out of 40 batters. Write an equivalent decimal.

Komok [63]

Answer:

0.275

Step-by-step explanation:

We want to write 11 out of 40 batters as a decimal.

We can write 11 out of 40 as a fraction to get:

$\frac{11}{40}$

Note that:

$\frac{11}{40} = \frac{1}{4} \times \frac{11}{10}$

This implies that:

$\frac{11}{40} = 0.25 \times 1.1$

This gives us

$\frac{11}{40 } = 0.275$

The diameter of a circular tablecloth is 72 inches. Find the area and circumference. Use 3.14 as an approximation for pi.

nalin [4]

Answer:

Part 1) The area is $A=4,069.44\ in^{2}$

Part 2) The circumference is $C=226.08\ in$

Step-by-step explanation:

step 1

Find the area

we know that

The area of a circle (circular tablecloth) is equal to

$A=\pi r^{2}$

we have

$r=72/2=36\ in$ ------> the radius is half the diameter

$\pi =3.14$

substitute

$A=(3.14)(36)^{2}$

$A=4,069.44\ in^{2}$

step 2

Find the circumference

we know that

The circumference of a circle (circular tablecloth) is equal to

$C=\pi D$

we have

$D=72\ in$

$\pi =3.14$

substitute

$C=(3.14)(72)$

$C=226.08\ in$

I don't know how to answer the top two and I don't know if the bottom one is correct, help me please

Tpy6a [65]

1) How many 3/4 does it take to make 9/2?

     Now look at this, 3/4 x 6 = 4 1/2. 4 1/2 is the same as 9/2

   3/4 + 3/4 + 3/4 + 3/4 + 3/4 + 3/4 ---> takes 6, 3/4's to make 9/2

2) How many 3/4's go into 9/2?

    This is the same question as the 1st one so the answer is 6 :)

3) 9/2 divided by 3/4 = ??

         Use the KEEP< CHANGE< FLIP method, so it turns into I
                                                                                                    I
                                                                                                    I
                                                                                                    I
      9/2 x 4/3                       < -------------------------------------          I

This is equal to 36/6 which is 6 :)

The answer is 6 for numbers 1, 2, and 3 :)
