PLZ HURRY! Jenny mixed 4 kg of mixed nuts containing 16% peanuts with 12 kg of mixed nuts containing 40% peanuts. What percent of the new mixture if peanuts?

Answers

Answer:

34%

n = new % = Answer

(4kg x 16%) + (12kg x 40%) = (New Percentage(Total kg))
(.16 x 4) + (.4 x 12) = n(4 + 12)

Simplify above to get:

.64 + 4.8 = 16n
.64 + 4.8 = 5.44
5.44 = 16n
Divide both sides by 16
.34 = n
34%
Convert .34 to Percentage by moving decimal to the right 2 times.

Find the missing angle.

Answers

Answer:

total angle of a triangle = 180°

other two angles = 85° , 65°

∴ the missing angle = 180 - ( 85 + 65 )

= 180 - 150

= 30

hope this answer helps you..

please mark as brainliest... thank you!

the missing angle is 30°. you add the other two and subtract it from 180° since a triangle is always 180°. hope this helps? can i please get brainliest?

Step-by-step explanation: it would be josh has 2 jars of jelly

The number of coins in the red jar is 83 and the number of coins in the red jar is 110.

How to find the equation of the words problem?

The blue jar has 27 more coins than the red jar. There are total of 193 coins.

The number of coins in each jar can be calculated as follows:

Using equation,

let

x = coins in the red jar

Therefore,

coins in the blue jar = 27 + x

Therefore,

total coins in the jars = x + 27 + x

193 = x + x + 27

193 - 27 = 2x

166 = 2x

divide both sides by 2

x = 166 / 2

x = 83

Therefore,

number of coins in the red jar = 83

number of coins in the blue jar = 83 + 27 = 110

PHOTOGRAPHY Joseph subscribes to a website for processing his digital pictures. The subscription is $8 and 5-by-7-inch prints are $0.15 each. How many prints does Joseph purchase if the charge for January is $11?
help now i beg i will give brainlist plz

Answers

The answer is 20 prints.

Explanation:
The total cost is $11. Joseph paid $8 for the SUBSCRIPTION (NOT PRINTS) already, so we take away the 8 from 11, equaling in $3 left.
The question is asking for the amount of prints. Now that we only have 3 dollars left, we just divide that by the cost of each print (0.15) to see how many prints can go into that cost.
3 divided by 0.15 is 20. So, Joseph purchased 20 prints.

theoretical does not always mean that it will happen, such as flipping a coin.

it will say there is a 1/2 chance to get heads or tail.

experimental is what actually happens when you test it out. say you flip a coin 10 times and only get heads 3 times. if it was the theoretical possibility then it would say 5 heads and 5 tails.
