1/2

Step-by-step explanation:

There are 6 marbles that are either red or green out of 12 total marbles, so you have:

6/12 = 1/2

Answer:

1/2

Step-by-step explanation:

To find the probability, you need to put the number of what you want to know the probability of over the total. In this case, we want to know what the probability of red and green over the total is. So, hence the equation:

[tex]\frac{5+1}{12}[/tex] or [tex]\frac{6}{12}[/tex] which can be simplified to [tex]\frac{1}{2}[/tex].

Answer:

(4ad) - 16/169c -1.

Step-by-step explanation:

Alright. Let's start.

(4ad) - [tex]\frac{1}{13}[/tex]b * [tex]\frac{16a}{13abc}[/tex] -1 is the expression.

So, by PEMDAS, we need to do the multiplication first. We can also say that 1/13b is the same as b/13.

(4ad) - 16ab/169abc -1     Now let's cancel out the b and a on numerator and denominator.

(4ad) - 16/169c -1.

The correct option is (C)

An equation is a mathematical expression that contains an equals symbol.

Given:

Sound travels= 1100 feet per second

Stations are 2 miles apart from each other, i.e., 10560 feet.

Using,

x²/a² + y²/b²=1

So, 2c= 10560

c=5280

and, 2c-2a +3300 = 10560

2a= 3300

a= 1650

So, b²= c² - a²= 25155900

x²/2722500 + y²/25155900=1

Answer:

The X intercepts is 1 and 5

All the equivalent expressions are,

1.35X and (1+0.35)x.

The correct options are a and d.

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

The value of X increased by 35%.

Here, we will use the percentage formula.

The value is increased by 35%.

That means,

100 + 35 = 135%

135% in decimal form is 1.35.

In expression form as subject to X,

X(1.35)

In expressed form,

= X + 0.35X

= 1.35X

Therefore, equivalent expressions are 1.35X and (1+0.35)x.

Answer:

Step-by-step explanation:

to prove that, that is a right triangle you use the theorem that the two shorter sides square added equals the longest side squared

so if its a right triangle then 10^2+12^2 will equal 15^2

10^2+12^2=244

15^2=225

225 does not equal 224 so that is not a right angle

Answer:

If this is talking about 58 - 110 then that would be -52.

The estimated answer 58-110 is -40.

A number system is defined as a system of writing to express numbers.

The given expression is 58-110

Fifty eight minus one hundred ten.

In the given expression the operator used is minus which is subtraction

The result of 58 minus 110 is -52.

58-110=-52

To estimate this, we can round 58 to 60 and 110 to 100,

the estimated answer would be 60 - 100 = -40.

Sixty minus hundred equal to minus forty

Hence, the estimated answer 58-110 is -40.
