Answer 1

Answer:

1) 20 cm

2) 22.4 in

3) 15 ft

Step-by-step explanation:

For this question, you have to use the Pythagorean theorem.

Why?

Well, because it is a right triangle and you have 2 sides given and you want to find the third side.

Now let's solve this problem!

For number 1 we have:

a = 16 cm and B = 12 cm

you need to find the 3rd side which is c (aka the hypothenuse)

so let's write the equation:

a^2 + b^2 = c^2

Then we substitute with what we have given.

16^2 + 12^2 = c^2

Using a calculator solve the equation

400 = c^2

Now we have to find the square root from both sides of the equation.

c = 20 cm (That's the final answer)

For number 2 we have:

a = 10 in and b = 20 in

we follow the same steps as in number 1

a^2 + b^2 = c^2

10^2 + 20^2 = c^2

500 = c^2

c = 22.4 in (That's the final answer)

For number 3 we have:

a = 9 ft and b = 12 ft

a^2 + b^2 = c^2

9^2 + 12^2 = c^2

225 = c^2

c = 15 ft (That's the final answer)

Which number is an irrational number?
A.) 3.5
B.) √36
C.) √48
D.) 37/100

Answers

A because the others are fractions and not a whole number

Answer:

the answer is c

Step-by-step explanation:

square root of 36 = 6 = 6 / 1D. 37 / 100 is already a fraction. Hence, the only number that cannot be written as a fraction is the square root of 48. The answer is C: the square root of 48 is an irrational number.

Sturdy’s paper plates cost $3.12 for 24 plates. Tough’s paper plates cost $4.32 for 32 plates. Which is the better buy?

Answers

Answer:

Sturdy's paper plates

Step-by-step explanation:

Let's see how much 8 plates cost:

Sturdy

24/3=8

$3.12/3= $1.04

Tough

32/4=8

$4.32/4=$1.08

$1.04<$1.08

Because Tough's paper plates costs 4 cents more for 8 plates, Sturdy's paper plates are the better buy.

Witch is better to buy $6.15 for 24 fl oz of dishwashing liquid or $9.60 for 42 fl oz of dishwashing liquid?

Answers

Answer:

$9.60 for 42 fl oz

Step-by-step explanation:

$6.15 x 2=$12.30

$12.30 for 44 fl oz

$12.30-$9.60=$2.70

you would be paying $2.70 for 4 fl oz when 4 fl oz is 93 cent

Answer:  42 fluid ounce unit of dish soap.

Step-by-step explanation: Why? Well, 24 times 2 gives you 48 fluid ounces for $12.30. But for just 4 less fluid ounces of soap, you pay $9.60. This is just over a dollar for every two ounces of soap.  So $12.30- $9.60= $2.70. this shows you`d need to buy two 24 ounce bottles. *So if you ONLY BUY ONE 24 OUNCE SOAP* you are getting a bad deal. In order to make a better deal buy two 24 ounce bottles to get four more ounces and pay $2.70 more. Hence you only ask about buying one, so 42 ounces is your go to choice.
