Answer:

8.6

Step-by-step explanation:

This uses the Pythagorean Theorem

a^2 + b^2 = c^2

a = 5

b = 7

c = ?

5^2 + 7^2 = c^2

25 + 49 = c^2

74 = c^2

sqrt(c^2) = sqrt(74)

c = 8.60 which when rounded = 8.6

What is 4.3(v+2.5)=8.11+4v

True [87]

Answer:

-8.8

Step-by-step explanation:

We begin by simplifying the parenthesis through multiplication. Parenthesis is a structure which signals multiplication happening.

$4.3(v+2.5)=8.11+4v\\4.3v+10.75=8.11+4v$

We now begin combining like terms across the equal sign by performing the inverse or doing the opposite. Move first the 8.11 by subtracting it from both sides.

$4.3v+10.75-8.11=8.11-8.11+4v\\4.3v+2.64=4v$

Now, move 4.3v across by subtracting it from both sides.

$4.3v-4.3v+2.64=4v-4.3v$

$2.64=-0.3v$

Finally, we divide both sides by the coefficient of v.

$\frac{2.64}{-0.3} =\frac{-0.3v}{-0.3} \\-8.8=v$

Naily [24]

Given: The information provided in the table shown

To Determine: From the options provided, the correct option that best describe the information given in the table

Solution

Given that 28% of the children used toothpaste. From the table

$Children(toothpaste)=\frac{0.07}{0.25}=\frac{7}{25}\times100=28\%$

Let us calculate the percentage of adult that used toothpaste

$Adult(toothpaste)=\frac{0.08}{0.75}=\frac{8}{75}\times100=10.667\%\approx11\%$

Hence, a smaller percentage of adults (about 11%) use the toothpaste.

The correct option is OPTION C
