Using a model can help you write a fraction with a denominator of 10 or 100 as a decimal can be written as :

255/10 = 25.5

1425/100=14.25

<h3>What is a model?</h3>

Model serves as the representation of a person or thing or of a proposed structure .

Since the the fraction has 10 as its denominator, the decimal point will be put after the first number from the left, if the denominator is 100 , it will be put after the second number from the left, for instance,

255/10 = 25.5

1425/100=14.25

Find the value of x. If your answer is not an integer express it in simplest radical form.

statuscvo [17]

Answer:

Step-by-step explanation:

To find the value of x, using Pythagorean theorem.

7) x² = 12² + 12²

= 144 + 144

= 288

x = √2*12*12

x = 12√2

8) x² + 9² = 18²

x² + 81 = 324

x² = 324 - 81

x² = 243

x = √3*9*9

x = 9√3

If a musician uses his credit card to pay for a new violin that costs $2,900 and does not pay on it until the second month, what

OLEGan [10]

Answer:

$97.15.

Step-by-step explanation:

We have been given that a musician uses his credit card to pay for a new violin that costs $2,900 and does not pay on it until the second month. The interest rate of credit card is 3.35% monthly.

We will use interest formula to solve our given problem.

$I=PrT$ , where,

$I=\text{Interest}$ ,

$P=\text{Principal amount}$ ,

$r=\text{Interest rate in decimal form}$ ,

$T=\text{Time}$

Let us convert our given interest rate in decimal form.

$3.35\%=\frac{3.35}{100}=0.0335$

Upon substituting our given values in interest formula we will get,

$I=2,900*0.0335*1$

$I=2,900*0.0335$

$I=97.15$

Therefore, the monthly interest charge at the end of the 1st month will be $97.15.

A 150 pound woman would receive 24grams of a certain medicine. How many grams should 120 pound woman receive?

shtirl [24]

Answer:

19.2 grams

Step-by-step explanation:

Assuming it is a straight proportion, then the givens are

w1 = 150 pounds

m1 = 24 grams

w2 = 120 pounds

m2 = x

m = medication amount.

w = weight

Equation

m1/w1 = m2/w2

Solution

24/150 = x / 120 Multiply both sides by 120

24 * 120/150 = x 120 /120

2880/150 = x Do the division

19.2 grams = x The amount the 120 pound woman should receive.

write an equation for the line that is perpendicular to the given line and passes through the given point y-3=8/3(x+2);(-2,3)

Stolb23 [73]

Answer:

$y-3=-\frac{3}{8} (x+2)$

Step-by-step explanation:

We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point (8,1) and a slope from the equation. We will chose point-slope since we have a point and slope.

Point slope: $y-y_1=m(x-x_1)$

$m\neq \frac{8}{3}$ in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is $m=-\frac{3}{8}$ .

We will substitute $m=-\frac{3}{8}$ and $x_1=-2\\y_1=3$ .

$y-3=-\frac{3}{8} (x-(-2))$

$y-3=-\frac{3}{8} (x+2)$

This is the equation of the line perpendicular to the equation given that crosses through (-2,3).
