Answer:

m = 38.44

Step-by-step explanation:

Let's consider the following proportion.

$18.45/m gal = $3.60/7.5gal

According to the cross products property of proportions, the product of the means is equal to the product of the extremes.

$18.45 × 7.5gal = m gal × $3.60

m gal = $18.45 × 7.5gal/ $3.60

m gal = 38.44gal

m = 38.44

\dfrac{\$18.45}{n \text { gallon}}  =  \dfrac{\$3.60}{7.5 \text { gallon}}

Cross multiply
n \times \  3.60 = 7.5 \times \  18.45

Combine like terms
3.60n = 138.375

Find n
n = 138.375\div 360

Answer
n = 0.38 \text { (nearest hundredth)}

3. 'a' and 'b' are the intercepts made
Julli [10]

Given:

'a' and 'b' are the intercepts made  by a straight-line with the co- ordinate axes.

3a = b and the line  pass through the point (1, 3).

To find:

The equation of the line.

Solution:

The intercept form of a line is

\dfrac{x}{a}+\dfrac{y}{b}=1         ...(i)

where, a is x-intercept and b is y-intercept.

We have, 3a=b.

\dfrac{x}{a}+\dfrac{y}{3a}=1           ...(ii)

The line  pass through the point (1, 3). So, putting x=1 and y=3, we get

\dfrac{1}{a}+\dfrac{3}{3a}=1

\dfrac{1}{a}+\dfrac{1}{a}=1

\dfrac{2}{a}=1

Multiply both sides by a.

2=a

The value of a is 2. So, x-intercept is 2.

Putting a=2 in b=3a, we get

b=3(2)

b=6

The value of b is 6. So, y-intercept is 6.

Putting a=2 and b=6 in (i), we get

\dfrac{x}{2}+\dfrac{y}{6}=1

Therefore, the equation of the required line in intercept form is \dfrac{x}{2}+\dfrac{y}{6}=1.

How does doubling the base effect the perimeter of the triangle
Contact [7]

i think it will make it smaller due to the base being longer which stretches out the two sides and makes less space inside of the triangle
