a rectangle has a width of 4 cm and a length of 8cm is scaled by a factor of 6.what are the side lengths of the scaled copy
vichka [17]

Answer:

\huge\boxed{\text{Width: } 24 \ \ \ \text{Length: } 32}

Step-by-step explanation:

When we scale an object by a scale factor, the side lengths become the scale factor times bigger than the previous sides. Therefore, with a scale factor of 6, the side lengths would be multiplied by 6.

4 \cdot 6 = 24\\\\4 \cdot 8 = 32

Hope this helped!

Consider the sequence: 3, 8, 13, 18, 23, ...The recursive formula for this sequence is:an = an-1 + 5In a COMPLETE sentence, expl
Akimi4 [234]

Answer:

a_8=38

Step-by-step explanation:

<u>Recursive sequence </u>

In a recursive sequence formula, each term a_n is computed as a function of one or more previous terms. In the formula

a_n=a_{n-1}+5

n is the number of the term we want to calculate. If n=8, then the formula becomes

a_8=a_{7}+5

We can see a_{n-1} is the previous term. It means we need a_7 to be able to compute a_8. But we also need a_6 to compute a_7 and so on until some known data is reached. The question provides five terms, a_5=23.

a_6=a_5+5=28

a_7=a_6+5=33

a_8=a_7+5=38

a_8=38

How many pints are in 720 milliliters?
Rom4ik [11]

Answer: There are 1.52 pints in 720 mililiters.

Step-by-step explanation:

You need to remember that there are 473.176 mililiters in 1 pint.

Therefore, having 720 mililiters, you need to make the corresponding conversion from mililiters to pints.

Then, you get that 720 mililiters to pints is:

=(720mililiters)(\frac{1pint}{473.176mililiters})\\\\=1.52pints

Therefore, the answers is: There are 1.52 pints in 720 mililiters.

What is the value of x is in the solution set of 8x-6&gt;12+2x?​
fiasKO [112]

Answer:

see explanation

Step-by-step explanation:

Given

8x - 6 > 12 + 2x ( subtract 2x from both sides )

6x - 6 > 12 ( add 6 to both sides )

6x > 18 ( divide both sides by 6 )

x > 3

Any value of x greater than 3 will be in the solution set
