$7293 I think....

What symbol makes the sentence true? -3½ ? -3 5/9

kvasek [131]

$\frac{-63}{18}\geq \frac{-64}{18}$

So, Option A is correct

Step-by-step explanation:

We need to identify the expression, that makes the sentence true:

$-3\frac{1}{2}?-3\frac{5}{9}$

First converting mixed fraction into improper fraction

$-3\frac{1}{2}=\frac{-7}{2}$

$-3\frac{5}{9}=\frac{-32}{9}$

For comparing both terms, their denominator should be same.

Multiplying $\frac{-7}{2}$ by 9 and $\frac{-32}{9}$ by 2 to make denominator same.

$\frac{-7*9}{2*9}=\frac{-63}{18}$

$\frac{-32*2}{9*2}=\frac{-64}{18}$

So, comparing terms $\frac{-63}{18}\,\,and\,\,\frac{-64}{18}$

$\frac{-63}{18}? \frac{-64}{18}\\\frac{-63}{18}\geq \frac{-64}{18}$

So, Option A is correct

Coffee is sold in two different sized canisters. The smaller canister has a diameter of 9 cm and a height of 12 cm. The larger c

Mademuasel [1]

Answer:

Volume of smaller canister = 763.02 $cm^3$

Surface area of smaller canister = 466.29 $cm^2$

Volume of larger canister = 6104.16 $cm^3$

Surface area of larger canister = 1865.16 $cm^2$

Volume becomes 8 times by doubling the size and surface area becomes 4 times by doubling the size.

Step-by-step explanation:

Given that :

Diameter of Smaller canister = 9 cm

Height of Smaller canister = 12 cm

Larger canister is double the size of smaller one i.e. height and diameter are doubled.

To find:

Volume and surface area of each canister and their comparison.

Solution:

First of all, let us have a look at the formula of volume and surface area of a cylinder.

Volume, $V=\pi r^2h$

Surface Area, $A=2\pi r^2+ 2\pi rh$

where r and h are the radius and height of the cylinder respectively.

Radius is half of diameter.

Radius of smaller canister is given by:

$r_1 = \dfrac{9}{2} = 4.5\ cm$

Height, $h_1 =12\ cm$

Volume, $V_1=\pi (4.5)^2 \times 12 = 763.02\ cm^3$

Surface Area, $A_1 = 2 \pi \times 4.5 ^2 + 2\pi\times 4.5 \times 12 = 466.29 \ cm^2$

Now, Diameter / Radius and height of larger canister are doubled of smaller one.

Radius of larger canister is given by:

$r_2 = \dfrac{9}{2} \times 2 = 9 cm$

Height, $h_2 =12\times 2 = 24\ cm$

Volume, $V_2=\pi (9)^2 \times 24 = 6104.16\ cm^3$

Surface Area, $A_2 = 2 \pi \times 9 ^2 + 2\pi\times 9\times 24= 1865.16 \ cm^2$

Comparing the results, we can easily see that:

$V_2 = 8 \times V_1\\A_2 = 4 \times A_1$

i.e. Volume becomes 8 times by doubling the size and surface area becomes 4 times by doubling the size.

PLZZZZZ HELPPPPPPPP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

shtirl [24]

Answer:

y = 3

x = 1

y = 1.5

x = 2

Step-by-step explanation:

For the first x point, look at the graph where x is 0. When x is 0, y is 3. So the first one is 3. For the second one, there is a point on the graph where y is 4. Where y is 4, x is 1, so you the second answer is 1. For the third one, find the y point where x is -1. At the x value, -1, y is 1.5. For the last one, where y is 5, x is 2.
