You could not make a triangle with these measurements, because a triangle equals 180°, how ever if you add 45 + 90 + 10 you would get 145°. So you could not make a triangle with these measurements.

A company that offers tubing trips down a river rents tubes for a person to use for $20 and “cooler” tubes to carry food and wat
aivan3 [116]

The group rent 11 river rent tubes and 4 cooler tubes.

Step-by-step explanation:

Rent for river rent tube = $20

Rent for cooler tubes = $12.50

Total spent = $270

Total tubes rented = 15

Let,

x be the number of river rent tube.

y be the number of cooler tubes.

According to given statement;

x+y=15    Eqn 1

20x+12.50y=270    Eqn 2

Multiplying Eqn 1 by 20

20(x+y=15)\\20x+20y=300\ \ \ Eqn\ 3

Subtracting Eqn 2 from Eqn 3

(20x+20y)-(20x+12.50y)=300-270\\20x+20y-20x-12.50y=30\\7.50y=30

Dividing both sides by 7.5

\frac{7.5y}{7.5}=\frac{30}{7.5}\\y=4

Putting y=4 in Eqn 1

x+4=15\\x=15-4\\x=11

The group rent 11 river rent tubes and 4 cooler tubes.

A circular bicycle reflector has a diameter of 5 cm. What is the approximate area of the reflector? Use 3.14 to approximate pi a
grandymaker [24]

Answer:

Step-by-step explanation:

Area=pi×radius^2 so if diameter is 5 then radius is half that which is 2.5. So it should be a=3.14 × 2.5^2. I hope that's right.

How do we multiply numbers
zavuch27 [327]

To multiply a number, simply take a number (Let's say 4) and another number (Let's say 3). If you multiply 4 by 3, you are simply taking the number 4, and adding it to itself 3 times (4 + 4 + 4).

I hope this makes sense, please tell me if you need some more information.

Hope this helps!

The equation
a/4 = 2/3
do cross multiplication
8 = 3a
a = 8/3

Performing the expression.
= (a - 4) / 4
= (8/3 - 4) / 4
= (8-12 / 3)/4
= -4/3 / 4
= -1 / 3

So the answer is letter b.
