You have two pieces for fabric. One piece is 6 feet wide and the other piece is 7.5 feet wide. You want to cut both pieces into
My name is Ann [436]

Answer:

<em>Strips should be </em><em>1.5 ft wide.</em>

Step-by-step explanation:

Given:

Width of 1st piece = 6 ft

Width of 2nd piece = 7.5 ft

To find:

To find the maximum width possible to make strips of equal size from both the pieces.

Solution:

This problem can be visualized as if we are given two numbers and we have to find the Highest common factor for both of them i.e. HCF of 6 and 7.5 will be our answer.

Let us try to factorize the given factors:

7.5 = 3 \times 2.5 = \underline {3 \times 0.5} \times 5

6 = 3 \times 2 = \underline {3 \times 0.5 }\times 2

The common factors are highlighted above as underlined.

Therefore, the answer is 3 \times 0.5 = <em>1.5 ft </em>

<em></em>

<em>Strips should be </em><em>1.5 ft wide.</em>

The polynomial x^3-kx^2+kx+2 has a factor of (x-2). What is the value of k?
laiz [17]

\text{Let}~ f(x) = x^3-kx^2 +kx +2.\\\\\text{If}~ x-2~ \text{is a factor of}~ f(x)~ \text{then,}\\ \\f(2) =0\\\\\implies 2^3-k\cdot 2^2 +2k+2 =0\\\\\implies -4k+2k+8+2=0\\\\\implies 10-2k=0\\\\\implies 2k =10\\\\\implies k= \dfrac{10}2 = 5\\\\\\\text{Hence, the value of k is 5.}

You have $3.70 in dimes and quarters. You have 5 more
anygoal [31]

Answer:

Step-by-step explanation:

10x + 25y = 370

y = x + 5

10x+25(x+5)=370

10x+25x+125=370

35x=370-125

x=245/35

x=7 which is the number of dimes

x+7= 7+5= 12 which is the number of quarters

So you have 12 quarters. That means you have 7 dimes.
