How do you know if a whole number is a perfect square

Mathematics
1 answer:
kirill [66]3 years ago
4 0

Answer:

you simply think of a number that when multiplied by itself it will give you that whole number

Step-by-step explanation:

let's take for instance the number 4 it's a whole number and still a perfect square because when you think of a number from 1to 10, which number when you multiply by itself will give you four apart from 2

the greater of two numbers is 1 more than twice smaller. three times greater exceeds 5 times the smaller by 10. find the three n
krek1111 [17]
<h3><u>The value of the greater number is 15.</u></h3><h3><u>The value of the smaller number is 7.</u></h3>

x = 2y + 1

3x = 5y + 10

Because we have a value for x we can plug this value in to find the value of y.

3(2y + 1) = 5y + 10

Distributive property.

6y + 3 = 5y + 10

Subtract 5y from both sides.

y + 3 = 10

Subtract 3 from both sides.

y = 7

We can plug this value back into the original equation to find the value of x.

x = 2(7) + 1

x = 15

The slope of the given line is -1/3. The perpendicular line's slope is the opposite reciprocal of the given line's slope. So, the perpendicular line's slope is 3. Then we have slope intercept form y=mx+b

y=3x+b
We don't know "b" which is the y-intercept for this equation, but we have the coordinates (6, -1). We can use these to find the slope by plugging them into the equation.

-1=3(6)+b
-1=18+b
-1-18=18+b-18
-19=b
So, the resulting y-intercept is -19.

The final perpendicular equation would be y=3x-19

The probability distribution for a game is shown in the table below.
nydimaria [60]

Given:

It is given that

Probability of winning $ 0 = \frac{3}{10}

Probability of winning $ 100 = \frac{1}{5}

Probability of winning $ 200 = \frac{1}{10}

Probability of winning $ 500 = \frac{2}{5}

To find the probability of not winning a cash prize.

Explanation:

Not winning cash prize = winning $ 0

So,

Probability of not winning a cash prize

= Probability of winning $ 0

= \frac{3}{10}

Therefore,

The probability of not winning a cash prize is \frac{3}{10}. Option D.

Seven pounds of grapes cost 10.43. How much would 3 pounds cost?
KiRa [710]
To answer this we will find the unit rate by dividing. Lets do it:-

10.43 ÷ 7 = 1.49
1 pound of grapes = $1.49

CHECK OUR WORK:-

1.49 × 7 =  10.43
we were RIGHT!!!

Now lets multiply to see how much 3 pounds would cost. 

1.49 × 3 = 4.47

CHECK OUR WORK:-

4.47 ÷ 3 = 1.49
We were RIGHT!!

So, 3 pounds of grapes cost $4.47. 

Hope i helped ya!!
