It's A. P, Because you add all the sides of the rectangle to get 6+4+6+4= 20. Hope this helps!

In Satoru's hometown, the highest temperature ever recorded is 111°F.

finlep [7]

Answer:

Step-by-step explanation:

F=9/5C+32 should be F = (9/5)C + 32

We are given 111 degrees F and want the same temperature in degrees Celcius.

In F = (9/5)C + 32 multiply all three terms by 5:

5F = 9C + 160, which can be solved for C:

5F - 160 = 9C

Let F = 111. Then 555 - 160 = 9C, or

395 = 9C

Dividing both sides by 9, we get C = 395/9 = 43 8/9 degrees C

Find the surface area of this rectangular prism.

Alexeev081 [22]

Answer:

Surface area of the rectangular prism= $168 yards^2$

Step-by-step explanation:

Given Dimensions of the rectangular prism are:

$Length(L)= 9 yards\\\\Width(w)=2 yards \\\\Height(H)= 6 yards$

Surface Area of a rectangular prism=

$2(L*W+W*H+H*L)\\\\ =2(9*2+2*6+6*9)\\\\ =2(18+12+54)\\\\ = 2(84)\\\\$

= $168 yards^2$

The surface area of the rectangular prism is $168 yards^2$

The hikers plan to visit a scenic lookout. They will rest after they hike 2 miles. Then they will hike the remaining 1 3/4 miles

castortr0y [4]

Answer:

7 miles
1 3/4 gallons

Step-by-step explanation:

The distance to the lookout is the sum of distances before and after the rest stop:

... "to" distance = 2 mi + 1 3/4 mi = 3 3/4 mi

The distance from the lookout is 1/2 mile shorter, so is ...

... "from" distance = 3 3/4 mi - 2/4 mi = 3 1/4 mi

Then the total hike is ...

... total distance = "to" distance + "from" distance

... = 3 3/4 mi + 3 1/4 mi = 6 4/4 mi

... total distance = 7 mi

The water each hiker will bring is ...

... (7 mi) × (1/4 gal/mi) = 7/4 gal = 1 3/4 gal

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