Answer:

True

Step-by-step explanation:

Its true since it passes the vertical line test. How does the vertical line test work? You put a vertical line through a point and if it has only one point on that specific line it is a function. Note:hope this helps

There are 50 kcal per cup

Amount of kcal per bottle = ?

1 bottle = 4 cups

1 cup = 50 kcal

1 bottle = 4 cups = 4 x 50 kcal

1 bottle = 4 cups = 200 kcal

Therefore, there are 200 kcal in the whole bottle

LiRa [457]

Answer: 3000 stamps

Step-by-step explanation:

Given

Chris and Josh have 1800 stamps

Josh and Jessica have 2200 stamps

Jessica and Chris have 2000 stamps

Suppose Chris, Josh, and Jessica have $x,y, \text{and}\ z$ stamps

$\therefore x+y=1800\quad \ldots(i)\\\Rightarrow y+z=2200\quad \ldots(ii)\\\Rightarrow z+x=2000\quad \ldots(iii)\\\text{Add (i), (ii), and (iii)}\\\Rightarrow 2(x+y+z)=1800+2200+2000\\\Rightarrow x+y+z=3000$

Thus, all three have 3000 stamps

From his eye, which stands 1.59 meters above the ground, Francisco measures the

viva [34]

The height of the skyscraper to the nearest tenth is 234. 95 meters.

<h3>How to determine the height</h3>

From the information given, we have:

angle of elevation = 32°
length of the base, adjacent side = 376 meters
height of the skyscraper, opposite side = x meters

To determine the height of the elevator, let's use the tangent identity

We have that;

tan θ = opposite/ adjacent

The value of the opposite side is 'x' which is the height of the skyscraper and the value of the adjacent side is 376 meters which is the length of the base of the skyscraper

Now, substitute the values, we have;

tan 32 = x/ 376

cross multiply

x = tan 32 × 376

x = 0. 6249 × 376

x = 234. 95 meters

We know that the 'x' represents the opposite side and thus the height of the skyscraper

Thus, the height of the skyscraper to the nearest tenth is 234. 95 meters.

4x+3=3(x+3)

4x+3=3x+9

4x-3x=9-3

x=6

So The Father is 24 and the Son is 6
