Answer:

Explained below.

Step-by-step explanation:

Consider the addition below:

+ 29

Since the sum in the one's column is 18, a two-digit number, we separate the number as 1 ten and 8 ones.

We now, keep the unit digit 8 and carry over the 1 ten to the tenth column.

Hope this makes sense.

Serenity picked 75% of the apples of a tree in her backyard. If she picked 30 apples, how many apples were on the tree to begin

Stells [14]

Given:

Serenity picked 75% of the apples of a tree in her backyard.

She picked 30 apples.

To find:

The number of apples on the tree in the beginning.

Solution:

Let x be the number of apples on the tree in the beginning.

Serenity picked 75% of the apples of a tree in her backyard.

Number of apples picked = 75% of x

= $\dfrac{75}{100}x$

= $\dfrac{3}{4}x$

She picked 30 apples.

$\dfrac{3}{4}x=30$

Multiply both sides by 4.

$3x=4\times 30$

$3x=120$

Divide both sides by 3.

$x=\dfrac{120}{3}$

$x=40$

Therefore, the number of apples on the tree in the beginning is 40.

A skydiver parachutes to the ground. The height y (in feet) of the skydiver after x seconds is y = −10x + 3000. a) Graph the equ

Anna007 [38]

The graph of the equation is:

The x intercept of 300 means the skydiver lands on the ground after 300 seconds. The slope of -10 means that the skydiver falls to the ground at a rate of 10 feets per second.
