clint has 6 apple muffins, 2 corn muffins, and 4 bran muffins what fraction of muffins are bran weite the fraction in simplest f

Feliz [49]

Answer:

$\frac{1}{3}$

Step-by-step explanation:

The fraction of bran muffins is expressed as bran muffins over total muffins.

Total muffins = 6 + 2 + 4 = 12 and bran muffins = 4, thus

fraction = $\frac{4}{12}$ ← divide ( cancel ) each value by 4 )

fraction = $\frac{1}{3}$ ← in simplest form

Jodi's car used 12 gallons of gas to travel 456 miles. How many miles did her car travel per gallon of gas? Show your work. Answ

Sloan [31]

Answer:

The number of miles her car travel per gallon of gas is 38 miles per 1 gallon of gas

Step-by-step explanation:

Given

Size of Gas = 12 gallon of gas

Distance = 456 miles

Calculating the number of miles her car travel per gallon of gas.

This in calculated by distance/size of gas

By substituton, it becomes

Number of miles = 456 miles/12 gallons ------ divide

Number of miles = 38 miles / gallon.

Hence, the number of miles her car travel per gallon of gas is 38 miles per 1 gallon of gas

Find the line's slope and a point on the line.<br>y+4=3/2(x-3)

madreJ [45]

Answer:

slope = $\frac{3}{2}$ , point on line = (3, - 4)

Step-by-step explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) is a point on the line

y + 4 = $\frac{3}{2}$ (x - 3) ← is in point- slope form

with slope m = $\frac{3}{2}$ and (a, b) = (3, - 4)

If the price of a product is p (dollars), the number of units demanded is given by the equation q-pe-3p

Nat2105 [25]

Answer:

$\mathbf{E(p) = 1 - 3p}$

the estimate the percent change in q when the price is raised from $2.00 to $2.10 decreases by 25%

Step-by-step explanation:

Given that:

the number of units demanded $q = pe^{-3p}$

Taking differentiations ; we have,

$\dfrac{dq}{dp}=e^{-3p}+p(-3e^{-3p})$

$\dfrac{dq}{dp}=(1-3)e^{-3p}$

Now; the price elasticity of demand using the differentials definition of elasticity is:

$E(p) = \dfrac{dq}{dp}*\dfrac{p}{q}$

$E(p) =[(1-3)e^{-3p}]*[\dfrac{p}{pe^{-3p}}]$

$\mathbf{E(p) = 1 - 3p}$

(b) Use your answer from part (a) to estimate the percent change in q when the price is raised from $2.00 to $2.10.

The estimate of the percentage change in price is :

$=\dfrac{2.10-2.00}{2.00}*100 \%$

= 5%

From (a)

$\mathbf{E(p) = 1 - 3p}$

Now at p = $2.00

E(2) = 1 - 3 (2.00)

E(2) = 1 - 6

E(2) = -5

The percentage change in q = -5 × 5%

The percentage change in q = -25%

Thus; we can conclude that the estimate the percent change in q when the price is raised from $2.00 to $2.10 decreases by 25%
