The weight of a box varies directly as the volume of the box. If a 138-pound box has a volume of 23 gallons, what is the weight

kolezko [41]

Answer:

D. 150 pounds

Step-by-step explanation:

For be directly proportional, it has to be that as one value increases the other does it equally, so

If 138 pound box has a volume of 23 gallons for 25 gallons ?. For being directly proportional tha value must be higest

138 → 23 $x=\frac{25*138}{23} = 150$

x → 25

How to solve 8=3/4w on math

NeTakaya

When you have to divide by a fraction, you have to multiply the other number by the fraction's reciprocal.

8 = 3/4 w Divide by 3/4

w = 8/(3/4)

w = 8/ (3/4) = 8 x 4/3 Multiply by the numerator and divide by the denominator.

w = (8 x 4) / 3

w = 32 / 3

w = 10 2/3

Jane wishes to bake an apple pie for dessert. The baking instructions say that she should bake the pie in an oven at a constant

pychu [463]

Answer:

A=152

K= -Ln(0.5)/14

Step-by-step explanation:

You can obtain two equations with the given information:

T(14 minutes) = 114◦C

T(28 minutes)=152◦C

Therefore, you have to replace t=14, T=114 and t=28, T=152 in the given equation:

$114=190-Ae^{-14k} (I) \\152=190-Ae^{-28k}(II)$

Applying the following property of exponentials numbers in (II):

$e^{a}.e^{b}=e^{a+b}$

Therefore $e^{-28k}$ can be written as $e^{-14k}.e^{-14k}$

$152=190-Ae^{-14k}.e^{14k}$

Replacing (I) in the previous equation:

$152=190-76e^{-14k}$

Solving for k:

Subtracting 190 both sides, dividing by -76:

$0.5=e^{-14k}$

Applying the base e logarithm both sides:

Ln(0.5)= -14k

Dividing by -14:

k= -Ln(0.5)/14

Replacing k in (I) and solving for A:

$Ae^{-14(-Ln(0.5)/14)}=76\\Ae^{Ln(0.5)} =76\\A(0.5)=76$

Dividing by 0.5

A=152
