How many pounds of mixed nuts that contain 70% peanuts must Shannon add to 15 pounds of mixed peanuts that contain 20% peanuts t

o make a mixture with 40% peanuts
Mathematics
1 answer:
Degger [83]3 years ago

Answer:

10 pounds.

Step-by-step explanation:

Let x pounds be the amount of mixed nuts we require.

Amount of peanuts in this mix = 0.70x pounds. Amount of peanuts in the 20% mix = 0.20*15 = 3 pounds.

So we have the equation:-

0.70 x + 3 = 0.40(x + 15)

0.70 x + 3 = 0.40(x + 15)

0.70x + 3 = 0.40x + 6

0.70x - 0.40x = 6 - 3

0.30x = 3

x = 10.

How much work is done by a man who uses a force of 7 Newtons to push a box 3 meters across the room?
ElenaW [278]

The formula to calculate work done is -

Work done ( in joule, J) = Force (in Newton) X Distance (in meters)

So, we will use the formula to calculate work done,

Here, force is given as = 7 newtons

Distance is given as = 3 meters

So, work done will be -

Work done ( in joule, J) = 7 Newtons X 3 Meters

<u>Work done ( in joule, J) = 21 J (in joule)</u>

Write down how you skip-count by ten from 350 to 240
Mamont248 [21]

Answer: 350,340,330,320,310,300,290,280,270,260,250,240.


Step-by-step explanation:

To solve this exercise you must keep on mind the following information:

1. By definition skip counting is about counting by a number which is not the number 1.

2. Skip counting by ten from 350 to 240 means that you need to subtract 10 to a number to find the other one.

3. Therefore, you must subtract 10 to 350 and then you need to do this over and over again until you get 240.

A rectangle and a triangle with the same base and height have the same area.
OverLord2011 [107]
The answer is false because if you attach to triangles together in a way so that the figure would have 4 straight lines, you will get a rectangle. that means half of a rectangle is a triangle, so the area of both cannot be the same even if they have the same base and height.


for example the base and height of both is 3cm and 5cm.

area of the rectangle then would be,
area= base× height
=3cm×5cm=15cmsquared

then the area of the triangle would be,
area= base×height divided by 2
=3cm×5cm÷2= 7.5cm

so your answer is false
hope this helps....
