ikadub [295]

For ever input, there is one ouput

it means we can't repeat the same x with a different y
but repeats of y's are allowed

pick any numbers that haven't been used as an input

-5 isn't taken
0 is taken
11 is taken
-1 is taken
2 is not taken
17 is taken

so -5 and -1 or A and D are the answers

boyakko [2]

Step-by-step explanation:

Amelia got 56% of 75 so

(56/100)*75=(56*75)/100=4200/100=42

Hayden got 8/15 of 75 so

(8/15)*75=(8*75)/15=600/15=40

and Sophie that got 43 out of 75

so we see that Sophie got the highest points.

The circle graph shows how a family spends its annual income. If $37,800 is used for Housing and Clothing combined, what is the

astraxan [27]

Answer:

$90000

Step-by-step explanation:

From the pie chart,

Let the total annual income = $y

The percentage of housing = 28 %

The percentage of clothing = 14 %

The combined percentage of housing and clothing = 28+14 = 42 %

If the amount spent on both housing and clothing combined = $ 37800

Therefore,

y(42/100) = 37800

Solve for y

42y = 37800×100

42y = 3780000

y = 3780000/42

y = $90000

Hence, the total annual income is $90000

Find the Volume of the cylinder

JulsSmile [24]

$\huge{\underline{\underline{\sf{\red{Required\:Solution:-}}}}}$

<h3>Volume of cylinder B is greater.</h3>

<h2>For Cylinder A :-</h2>

$\displaystyle{\sf{\:\:\:\:\:\:\:\:r(radius)\:=\: \dfrac{7}{2}cm}}$

$\displaystyle{\sf{\:\:\:\:\:\:\:\:h(height)\:=\: 14cm}}$

$\displaystyle{\boxed{\sf{ Volume\:=\: \pi r^{2}h}}}$

Substitute the values and simplify it

$\displaystyle{\sf{\:\:\:\:\:\:\:\:\:\:= \dfrac{22}{7} \times \bigg(\frac{7}{2}^{2} \bigg)\times14}}$

$\large{\boxed{\sf{\orange{= 539 cm^{3}}}}}$

<h2>For Cylinder B:-</h2>

$\displaystyle{\sf{\:\:\:\:\:\:\:\:r(radius)\:=\: \dfrac{14}{2}cm=7cm}}$

$\displaystyle{\sf{\:\:\:\:\:\:\:\:h(height)\:=\: 7cm}}$

$\displaystyle{\boxed{\sf{ Volume\:=\: \pi r^{2}h}}}$

Substitute the values and simplify it.

$\displaystyle{\sf{\:\:\:\:\:\:\:\:\:\:= \dfrac{22}{7} \times (7^{2})\times7}}$

$\large{\boxed{\sf{\green{= 1078 cm^{3}}}}}$

<h3>By actual calculation of volumes of both the cylinders, it is verified that the volumes of cylinder B is greater.</h3>
