Part 1

<span>Using rounding or compatible numbers, we estimate the product

5\times2 \frac{3}{5}
to
5\times3

Therefore, the estimate of the product </span><span>5\times2 \frac{3}{5}, using rounding and compatible numbers is about 15.</span>



Part 2

<span>Using rounding or compatible numbers, we estimate the quotient

25\frac{7}{8}\div2 \frac{8}{9}
to
27\div3

Therefore, the estimate of the quotient </span><span>25\frac{7}{8}\div2 \frac{8}{9}, using rounding and compatible numbers is about 9.</span>



Part 3

Given that Mr. Garcia's class ate 3\frac{2}{3} pizzas, Mrs Rizzoli's class ate <span>4\frac{1}{8} pizzas, and Mrs. Tindal's class ate </span><span>3\frac{1}{4} pizzas.

Using benchmarks, we estimate the total number of pizzas eaten by all three classes as follows: </span>3\frac{3}{4}, 4 and <span>3\frac{1}{4}

Thus, the </span><span>total number of pizzas eaten by all three classes is given by

3\frac{3}{4}+4+3\frac{1}{4}=11

Therefore, </span>the <span>total number of pizzas eaten by all three classes is about 11.</span>

Answer:

≈40.25 Feet

Step-by-step explanation:

The diagnal length of the orchard is the hypotenuse of the triangal with side lengths of 36 and 18.

Therefore, to calculate that, set the hypotenuse as x.

36²+18²=x²

√1620≈ 40.25yards

Given a sphere with a diameter of 6 cm, find its volume to the nearest whole<br> number.
mezya [45]

Answer:

Volume of the sphere is 1.13\times 10^{-4}m^3

Step-by-step explanation:

It is given diameter of the sphere d = 6 cm = 0.06 m

Radius of the sphere

r=\frac{d}{2}=\frac{0.06}{2}=0.03m

We know that volume of the sphere is given by

V=\frac{4}{3}\pi r^3

Therefore ,

V=\frac{4}{3}\times 3.14\times  0.03^3

=1.13\times 10^{-4}m^3

Therefore volume of the sphere is 1.13\times 10^{-4}m^3

The expression 120-15x represents how many invitations Luanne has to address after x days. The expression 120 + 15(7-x) represen
Aloiza [94]

Answer:

not possible.

Step-by-step explanation:

number of invitations luanne  has to address after x days = 120-15x

number of invitations  Darius has to address after x days =  120 + 15(7-x)

so, if the number of invitations should be the same for both of them,

we have to equate their number of invitations

120-15x =  120 + 15(7-x)

subtracting 120 from both the sides,

-15x = 15(7-x) = 105 -15x

adding we 15x on both sides, we wont find any solution for x.

so, this isnt possible or the question must be wrong.
