Answer:

You write 75% as a decimal

which would be: 0.75

Answer:

.75 is it as a decimal

Step-by-step explanation:

When you have a percentage you always move two places to the left.

For example 67% , the decimal would be .67 ---->    _6_7% the lines are showing the two places you move. Also if you have 157% as a decimal it is 1.57 always move two places to the left no matter how big the percent is!!

Answer: 1:600

Step-by-step explanation:

From the question, we are informed that 12 m object is represented in a picture as being 2 cm.

To find the scale used, we needed to convert 12m to cm. Since 100cm = 1m, then 12m = 12 × 100 = 1200cm.

Therefore, a 1200cm object is represented in a picture as being 2 cm. The scale will be:

= 2/1200

= 1/600

= 1:600

This means that 1 centimeter in the picture represent 600 centimeter or 6 meters.

Answer:

x²+12x+27

Step-by-step explanation:

put the intercepts in intercept form which is a(x-p)(x-q)

That would be (x-3)(x-9)

Foil x²-9x-3x+27

Solve x²-12x+27

The equation would be:

y = 3x + 15

1) Table: It is pretty easy to do so, just plug in 0, 1, 2, 3, etc. for x and solve for y

2) graph (find slope): slope would be 3 shells/day that has a y-intercept of 15

3) you already defined the variables

4) 3(5)+15 = 15+15 = 30 seashells

Answer:

They will hit 180 seconds in 118.6 year

Step-by-step explanation:

Let M be the record for the mile (in seconds)

Let x be the year after 1958

So, x=(year)-19548

We are given that In the​ half-century since​ then, the record has decreased by 0.5 seconds per year

So, slope = m = 0.5

Now we will use point slope form

y = mx+c

So, we can express M as,

[tex]M=239.3-0.5 \times x[/tex]

Now we are supposed to find when they will hit 180 seconds

Substitute M = 180 in equation

180=239.3-0.5x

x=118.6

So, they will hit 180 seconds in 118.6 year

Answer:

Answer:

y=3x+1

Step-by-step explanation:

y=mx+b

y=3x+1

4=(3*1)+b

4=3+b

1=b

y=(3*1)+1

y=3+1

y=4

Answer:

69 3/4

Step-by-step explanation:

The stock market goes down to 50 3/4 at the beginning of the day

At the end of the day it goes up to 120 1/2

Therefore total change in the stock market from the beginning to the end of the day can be calculated as follows

= 120 1/2 - 50 3/4

= 241/2 - 203/4

= 279/4

= 69 3/4

Hence the total change in the stock market from the beginning to the end of the day is

69 3/4

An equation which can be used to model the total cost (y) for renting the cotton candy machine (x) hours is y = 18x.

An equation can be defined as a mathematical expression which shows that two (2) or more thing are equal.

A system of equations can be defined an algebraic equation that only has two (2) variables and can be solved simultaneously.

In order to solve this word problem, we would assign variables to the unknown numbers and then translate the word problem into algebraic equation as follows:

Translating the word problem into an equation, we have;

y = 72/4 × x

y = 18x
