Answer:

$481.25

Step-by-step explanation:

The formula for simple interest is i = p*r*t, in which p is the principal, r is the interest rate as a decimal fraction, and t is the time in years.

Here p = $3500, r = 0.055 and t =2.5 yrs, and so the simple interest is

i = ($3500.00)(0.055)(2.5 yr), or

i = $481.25

WRITE AN ALGEBRAIC EXPRESSION TO MODEL THE GIVEN CONTEXT. GIVE YOUR ANSWER IN SIMPLEST FORM. The original price of an item le

quester [9]

Answer:

The original price of an item less a discount of 20% is 0.8p where p is the original price

Step-by-step explanation:

Here, we want to write an algebraic expression that represents the original price of an item less a discount of 20%

Let the original price of the item be p

The meaning of the ‘less’ is that we are subtracting 20% of the price from the original price ;

So 20% of the price will be 20/100 * p = 20p/100 = p/5 = 0.2p

So let’s take this away from the original price p

That will be;

p - 0.2p = p(1-0.2) = 0.8p

Can someone help me on this

Sidana [21]

Answer:

Area = 702.9 or 703

Step-by-step explanation:

By Pythagoras the. first, we need to find the base!

(H)2 = (P)2 + (B)2

(82)2 = (18)2 + b2

6724 = 324 + b2

b2 = 6724-324

b2 = 6100

b = √6100

b = 78.1

note - they all are in square

Now, area of the triangle:-

1/2 * b * h

1/2 * 78.1 * 18

= 702.9

Hope it helps!

In the Cash Now lottery game there are 8 finalists who submitted entry tickets on time. From these 8 tickets, three grand prize

alexgriva [62]

Answer:

The number of ways is $\left n} \atop {}} \right. P_r = 336$

Step-by-step explanation:

From the question we are told that

The number of tickets are $n = 8$

The number of finalist are $r =3$

Generally the number of way by which this winners can be drawn and arrange in the order of $1^{st} , \ 2nd , \ 3rd$ is mathematically represented as

$\left n} \atop {}} \right. P_r = \frac{n\ !}{(n-r) !}$

substituting values

$\left n} \atop {}} \right. P_r = \frac{ 8!}{(8-3) !}$

$\left n} \atop {}} \right. P_r = \frac{ 8* 7*6*5*4*3*2*1}{ 5*4*3*2*1}$

$\left n} \atop {}} \right. P_r = 336$

Find at least 3 numbers that are palindromes and have square roots that are palindromes

Artemon [7]

Hey there!

Palindromes are numbers that can be written the same way backwards, such as 101 and 12321. You're looking for some numbers which are palindromes, and so are their square numbers.

Alright, I'll give you four of those:

121 is a palindrome, and its square root is 11, both palindromes. 11 x 11 = 121
484 is a palindrome, and its square root is 22, both palindromes. 22 x 22 = 484
10201 is a palindrome, and its square root is 101, both palindromes. 101 x 101 = 10201
12321 is a palindrome, and its square root is 111, both palinromes. 111 x 111 = 12321

Hope this helps!

Cube A has a volume of 9 in3. Cube B has a volume of 5 in3. Which of the following expresses the ratio of the side length of Cub

Troyanec [42]

Using the formula for the volume of a cube, it is found that the expression which gives the ratio of the side length of Cube A to the side length of Cube B is:

$r = \frac{3^{\frac{2}{3}}}{5^{\frac{1}{3}}}$
