Lyrx [107]
People with kids or babies always want them to eat natural foods with no preservation, even if are a bit more expensive than the other available options.What they care about is the quality and health of the kids.So keeping this point in head,most of the brands uses the technique to compete with the other in-market brands. And that's what the shopkeeper did in this case.
Mike should have read the listed ingredients on the baby food jar.I think both of them would have the same,except a few.

After 2014 the sales of new cell phones without cameras began declining. The number of people y (in thousands) who bought a cell
sukhopar [10]

Answer:

60,000 people

Step-by-step explanation:

Given the number of people y (in thousands) who bought a cell phone without a camera can be estimated by the equation y=-30x+240,

x is the number of years after 2014

<u>We can find the number of people that bought the cell phone in 2020. </u><u>In year 2020, that will be after 6years</u>

Substitute x = 6 into the expression

y=-30x+240

y=-30(6)+240,=

y = -180 + 240

y = 60

Since y is in thousands, hence the the number of people that have bought the cell phone by 2020 is 60,000 people

ABC is similar to ADEF. Find x. GEOMETRY
azamat

The value of x in the given diagram is 10

<h3>Similar triangles </h3>

From the question, we are to determine the value of the side labeled x

First, we will find the value of side |BC|

By the <em>Pythagorean theorem</em>, we can write that

|BC|² = 12² + 16²

|BC|² = 144 + 256

|BC|² = 400

|BC| = √400

|BC| = 20

Now,

Since ΔABC and ΔDEF are similar, we can write that

|BC| / |EF| = P ΔABC / P ΔDEF

But,

P ΔABC = 12 + 16 + 20 = 48

Thus,

|BC| / |EF| = P ΔABC / P ΔDEF becomes

20/ |EF| = 48/24

20/x = 2

x = 20/2

x = 10

Hence, the value of x in the given diagram is 10
