80 people were asked which was their favourite animal.

Alex787 [66]

Answer:

(a)Cat

(b)8 animals

Step-by-step explanation:

From the attached diagram:

Let the $\square$ be x.

Half of $\square$ =x/2

From the pictogram, we then have:

$Cat = x+\frac{x}{4} \\Dog=x+\frac{3x}{4}\\Giraffe=2x+\frac{x}{2}\\Monkey =x+\frac{x}{2}\\Dolphin=3x$

Therefore:

$x+\frac{x}{4} +x+\frac{3x}{4}+2x+\frac{x}{2}+x+\frac{x}{2}+3x=80\\8x+\frac{x}{4}+\frac{3x}{4}+\frac{x}{2}+\frac{x}{2}=80\\10x=80\\x=8$

So we have the following numbers

$Cat = x+\frac{x}{4} =8+\frac{8}{4}=10\\Dog=x+\frac{3x}{4}=8+\frac{3*8}{4}=14\\Giraffe=2x+\frac{x}{2}=2*8+\frac{8}{2}=20\\Monkey =x+\frac{x}{2}=8+\frac{8}{2}=12\\Dolphin=3x=3*8=24$

(a)Cat was the least popular

(b) $\square$ represents 8 animals

(c)

Number of People who preferred giraffe=20

Number of People who preferred dogs=14

Difference=20-14=6

Therefore, 6 more people preferred giraffes than dogs.

Simplify give ur answer in index form.

$\frac{( {j}^{4} \: \times \: {j}^{8}) ^{3} }{( {j}^{9} \: \div \: {j}^{2}) ^{2} }$

First we calculate the product of the denominator.

$\frac{( {j}^{12}) ^{3} }{( {j}^{9} \: \div \: {j}^{2}) ^{2} }$

Then we calculate the quotient of the numerator.

$\frac{( {j}^{12}) ^{3} }{( {j}^{7}) ^{2} }$

We multiply the exponents of the expression.

$\frac{ {j}^{36} }{ {j}^{14} }$

We divide.

$\boxed{ \bold{ {j}^{22} }}$

Problem 2

Brilliant_brown [7]

Answer:

Let the 'cart' total is x and total payment is y.

The sales tax is 5.6% added to the 'cart' amount and then shipping and handling fee added.

<u>There are three intervals as below and function added accordingly:</u>

0 < x ≤ 49.99 ⇒ y = x + 5.6% + 3.95 = 1.056x + 3.95
50 ≤ x ≤ 75.99 ⇒ y = x + 5.6% + 11.95 = 1.056x + 11.95
x ≥ 76 ⇒ y = x + 5.6% + 5.95 = 1.056x + 5.95

x = 74.50, this falls in the second interval
y = 74.50*1.056 + 11.95 = $90.62 (rounded )

y = 89.20, this is close to the number we got in part B and we assume it is same - the middle interval.

89.20 = 1.056x + 11.95
1.056x = 89.20 - 11.95
1.056x = 77.25
x = 77.25 / 1.056
x = 73.15 (rounded )

-----------------------------------------

<em>Note. Shipping and Handling charges seems incorrectly ordered. If so the answers above all should change accordingly.</em>
