Answer:

Step-by-step explanation:

total money = $2.25 = 225 cents

types of denomination in coins or cents are dimes and nickels

dime = 10 cents , nickel = 5 cents

twice of dimes to nickels

let no of dimes = x and no of nickels = y

our equation

10x + 5y = 225

x = 2y

10(2y) + 5y = 225

20y +5y = 225

25 y = 225

y=9

x =2y 2x9 = 18

so the number of dimes = 18 and nickels = 9

cross verification:

10x18 + 5x9 = 180 +45 = 225

If p(x) = x2 – 1 and q (x) = 5 (x minus 1), which expression is equivalent to (p – q)(x)?

svetlana [45]

Answer:

Step-by-step explanation:

P(x) = x² - 1 and Q(x) = 5(x - 1)

(P - Q)(x) = x² - 1 - 5(x - 1)

= x² - 1 - 5x + 5

= x² - 5x + 4

If the volume of each case is 1,000 cubic inches, could she use a table with a top that measures 212 feet long and 112 feet wide

skad [1K]

Answer:

You could not use a table with a top that is 2 1/2 feet long and 1 1/2 feet wide

Step-by-step explanation:

<u><em>The complete question is</em></u>

Elena needs to find a table that will fit three cube-shaped cases, each containing a frog.If the volume of each case is 1,000 cubic inches, could she use a table with a top that measures 2 1/2 feet long and 1 1/2 feet wide?Explain

step 1

Find the length side of the cube-shaped case

we know that

The volume of the cube is equal to

$V=b^3$

where

b is the length side of the cube

we have

$V=1,000\ in^3$

substitute

$1,000=b^3$

solve for b

$b=10\ in$

step 2

Convert feet to inches

$1\ ft=12\ in$

we have

$2\frac{1}{2}\ ft=2.5 (12)=30\ in$

$1\frac{1}{2}\ ft=1.5 (12)=18\ in$

step 3

Compare the dimensions of the table with the dimensions of the cube-shaped case

30 > 10

The length of the table is greater than the length side of the cube

18> 10

The width of the table is greater than the length side of the cube

therefore

You could not use a table with a top that is 2 1/2 feet long and 1 1/2 feet wide
