Use the distance formula in order to find the length of each side of the triangle. 

<span>>(7, 7) & (10, 3)
</span>√[(7-10)² + (7-3)²] = 5
<span>
></span><span>(10, 3) & (7, 3)
</span>√[(10-7)² + (3-3)²] = 3

>(7, 7) & (7, 3)
√[(7-7)² + (7-3)²] = 4

Adding all lengths (or solving for perimeter), we have: 5 + 3 + 4 = 12 

The seamstress will need 12 inches of lace.

An inequality that represents Denise's goal in terms of the number of hours spent running 'h'

550h\leq 5000

Given :

Denise wants to burn at least 5000 calories a week through running.

she can burn 550 calories per hour

Let 'h' be the number of hours spent

In 1 hour  she can burn  550 calories

In 'h' hours she can burn 550h calories

Given that she want to burn atleast 5000 calories in a week

Burn atleast 5000 calories means <=5000 calories

So , the inequality that represents Denise's goal is

calories burn in h hours  <= 5000 calories

550h\leq 5000

sammy [17]

The standard compound interest formula is

Future value after x years with an annual interest of i

=Present Value (1+i)^x [which is an exponential function]

for given present value of $360. interest=0.03 (3%) and a total of x years, above equation reduces to

Future value after x years

=360(1.03^x)

If a die is rolled one time, find probability of getting a number greater than 3 and an odd number.
Nadya [2.5K]

Answer:

\dfrac{1}{6}.

Step-by-step explanation:

It is given that a die is rolled one time. So,

Sample space : S=\{1,2,3,4,5,6\}

Number is greater than 3 : A=\{4,5,6\}

Number is odd : A=\{1,3,5\}

Number greater than 3 and an odd number : A\cap B=\{5\}

It is conclude that,

n(S)=6, n(A)=3,n(B)=3,n(A\cap B)=1

The probability of getting a number greater than 3 and an odd number is

P=\dfrac{n(A\cap B)}{n(S)}

P=\dfrac{1}{6}

Therefore, the required probability is \dfrac{1}{6}.
