Answer:

Step-by-step explanation:

the surface area = area of the 4 faces+ area of the 2 bases

4 *(15*8) + 2*( 8*6) = 480+96 = 576 cm²

if the length of the faces tripled, the two bases remain unchanged because the prism just gets taller on the same bases.

San Antonio to Dallas
65mph with 277 mi
277/ 65 = 4.26 hours
4.26 hours < 4.5 hours
so answer is YES

-----------------
Dallas to San Antonio: 277/4.75 = 58.32 mph
Lubbock to El Paso : 344/4.5 = 76.44 mph
San Antonio to Abilene: 261 / 4.25 = 61.41 mph
Dallas to Abilene: 185 / 3 = 61.67 mph

answer
lowest speed is :
Dallas to San Antonio in 4 3/4 hours

For the equation ae^ct=d, solve for the variable t in terms of a,c, and d. Express your answer in terms of the natural logarithm

saveliy_v [14]

We have been given an equation $ae^{ct}=d$ . We are asked to solve the equation for t.

First of all, we will divide both sides of equation by a.

$\frac{ae^{ct}}{a}=\frac{d}{a}$

$e^{ct}=\frac{d}{a}$

Now we will take natural log on both sides.

$\text{ln}(e^{ct})=\text{ln}(\frac{d}{a})$

Using natural log property $\text{ln}(a^b)=b\cdot \text{ln}(a)$ , we will get:

$ct\cdot \text{ln}(e)=\text{ln}(\frac{d}{a})$

We know that $\text{ln}(e)=1$ , so we will get:

$ct\cdot 1=\text{ln}(\frac{d}{a})$

$ct=\text{ln}(\frac{d}{a})$

Now we will divide both sides by c as:

$\frac{ct}{c}=\frac{\text{ln}(\frac{d}{a})}{c}$

$t=\frac{\text{ln}(\frac{d}{a})}{c}$

Therefore, our solution would be $t=\frac{\text{ln}(\frac{d}{a})}{c}$ .

Please explain how to solve this

natka813 [3]

I think it is 1.5×p.
Because for example:
If there were 99 science problems, then...
99÷3=33
99÷2=49.5
49.5÷33=1.5
33=p
The #of science problems=p×1.5
