You'd multiply the denominator (6) to both sides to get rid of it, if it was an equation it'd look like
y/6 = 9
*6. *6
y = 54

1) Multiply both sides by 6.

y ≤ 9 × 6

2) Simplify 9 × 6 to 54

So, y ≤ 54, is your answer.

Shelly bought 7 boxes of fish food and 2 packets of cat food. Each box of fish food contained 6 pouches, and each packet of cat

AfilCa [17]

Answer: 34 more pouches

7 boxes - fish food; 1 box contained 6 pouches

Total amount of fish food is 7 × 6 = 42 pouches of fish food

2 packets - cat food; 1 packet contained 4 pouches

Total amount of cat food is 2 × 4 = 8 pouches

How many more pouches of fish food than cat food did Shelly buy?

42 pouches - 8 pouches = 34 pouches

Therefore there was 34 more pouches of fish food than cat food

What is the measure of each interior angle in a regular 30-gon?

Rasek [7]

Exterior angles always add up to 360 degrees so for 30-gon each exterior angles is 12 degrees (360/30)

To get the interior angles you subtract 180 from 12 to get 168 degrees

Dr. Steve is working with a new radioactive substance in his lab. He currently has 64 grams of the substance and knows that it d

4vir4ik [10]

Remember that the general decay equation is:
$y=A(1-r)^{x}$
where
$y$ is the amount after a time $x$
$A$ is the initial amount
$r$ is the the decay percent in decimal form

The first ting we are going to do is find $r$ by dividing our decay rate of 25% by 100%: $r= \frac{25}{100} =0.25$ .
We also know from our problem that $y=64$ . Lets replace $y$ and $r$ in our formula:
$64=A(1-0.25)^{x}$
$64=A(0.75)^{x}$
We know now that our decay rate is 0.75, and since 0.75<1, we can conclude that this situation represents exponential decay.

Now, to find the initial amount, we are going to solve our equation for $A$ :
$64=A(0.75)^{x}$
$A= \frac{64}{0.75 ^{x} }$
Notice that $A$ will depend on the number of ours $x$ .

What is the area of and the perimeter of this triangle?

Veseljchak [2.6K]

Answer:

A = 40 square yards; P = 33 yards.

Step-by-step explanation:

Perimeter of the triangle

= ( 8 + 15 + 10)

= 36 yards.

Area of the right angled triangle

= 1 /2 * 10 * 8

= 40 square yards.

Hope it will help :)
