Varvara68 [4.7K]

Step-by-step explanation:

Amount (A) = ?

Principal (P) = $85,000

Rate (r) = 6%

Time (t) = 8 years

Simple interest formula;

A = P(1 + rt)

A = $85,000(1 + 0.48)

A = $125,800

geniusboy [140]

Answer:

6 liters

Step-by-step explanation:

Given:

Renata's recipe for her famous Kale 'n' Clam Quencher calls for kale juice and clam juice in a 3:1 ratio.

If Renata pours 18 liters of fresh kale juice, how many liters of clam juice should she add to maintain this ratio?

Solution:

Ratio to be maintain by using kale juice and clam juice = 3 : 1 ( given)

Renata pours fresh kale juice = 18 liters

We have to calculate quantity of clam juice should be added to maintain this ratio:-

Let quantity of clam juice should be added = x

<u>Ratio to be maintain : : quantity of kale juice : quantity of clam juice</u>

3 : 1=18:x\\ \\ \frac{3}{1} =\frac{18}{x} \\ \\

By cross multiplication:

3x=18

By dividing both sides by 3

x=6\ liters

Thus, 6 liters of clam juice should she add.

What is the exact volume of a cylinder with a base height of 30, and a radius of 13
Tcecarenko [31]
Volume of a cylinder is \pir^{2}h. This is basically the area of a circle multiplied by the height. You can think of it as congruent circles being stacked on top of each other to create a cylinder. With the given information, all we have to do is substitute the values into the variables

V = \pir^{2}h.
V = \pi(13)^{2}x30
V = \pi x 169 x 30 = \pi 5070

Hope this helps! 
(btw if it asks for "exact" anything, leave the pi. Pi is the ratio of the circumference to its diameter, so not every circle will have a pi of 3.14.)

Find each percent of change. Round to the nearest whole percent if necessary. State whether the percent of change is an increase
Alex787 [66]
So first we see if increase or decrease
180<210
it is increase

then we assume that
percent change
find how much change took place
210-180=30
30/180=x% change
percent means parts out ofo 100s so x%=x/100
30/180=x/100
multiply both sides by 100
3000/180=x
16.66666=x
answe ris 16.6%
