Last month, Cho opened a checking account. Since then, he withdrew 21 dollars, which was 84% of the balance. How much did
Cho have in the account last month?

At the given point, Chad has used 176 feet of light

From the question, we have the following parameters that can be used in our computation:

Length = 55 feet

Width = 48 feet

We start by calculating the distance from the end of the width till the beginning of the length

This is represented by the following Pythagoras theorem

Distance = √(Length² + Width²)

So, we have

Distance = √(55² + 48²)

Evaluate

Distance = 73

The number of feet is then calculated as

Feet = Length + width + distance

So, we have

Feet = 55 + 48 + 73

Evaluate

Feet = 176

Hence, the total distance is 176 feet

The inequality that represents the condition will be b + 10.7 ≥ −3.2. Then the correct option is C.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

Let the number be 'b'. Then the statement "the sum of a number and 10.7 is at most −3.2" is written in mathematical form. Then we have

b + 10.7 ≥ −3.2

Thus, the inequality that represents the condition will be b + 10.7 ≥ −3.2. Then the correct option is C.

Answer:

it is 24 and 24x1/2 but you can count 1/2 as 2 which will get you to 48 division 12

Answer:

B. 50

Step-by-step explanation:

Let x be the number of coupons sent to existing members.

The number of coupons sent to potential members is 4 times the number of coupons sent to existing members, or 4x.

The total number of coupons sent is the sum of the number of coupons sent to existing members and the number of coupons sent to potential members, or x + 4x = 5x.

The club sent out 250 coupons, so 5x = 250.

Dividing both sides of the equation by 5, you get x = 250 / 5 = 50.

Therefore, the club sent 50 coupons to existing members.

What is probability ?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

The probability that it will rain tomorrow is 0.2

i.e.

P(it will rain tomorrow )=0.2

Now probability that it won't rain tomorrow is,

P(it won't rain tomorrow )=1- P(it will rain tomorrow)=1-0.2=0.8

Here, we have

Given inequalities

x - y < 5

y ≥ 2x - 4

We have to describe the graph of the system of inequalities.

For, x < 5+y

x = 5-y

We put y = 0, we get

x = 5

We put x =0, and we get

y = 5

Hence, the x = 5-y line passes through (0,5) and (5,0).

For, y ≥ 2x - 4

y = 2x -4

We put x = 0, and we get

There are 7776 different outcomes possible when 5 dice of different colors are rolled.

The ratio of favorable outcomes to the total number of outcomes of an event is said to be the probability of that event.

P(E) = n(E)/n(S)

It is given that, there are 5 dice with different colors.

There are 6 outcomes for each die rolling. That is the number coming up on each die when it is rolled (1, 2, 3, 4, 5, 6).

So, for five dice when rolled, the number of possible outcomes is

n = 6 × 6 × 6 × 6 × 6

⇒ n = 7776

Therefore, 7776 different outcomes are possible.

However, a correlation between two variables does not always imply that a change in one variable is the reason for a change in the values of the other. There is a causal link between the two occurrences, which means that causation shows that one event is the outcome of the occurrence of the other event.

Causal relationships between variables may consist of direct and indirect effects. Direct causal effects are effects that go directly from one variable to another. Indirect effects occur when the relationship between two variables is mediated by one or more variables.

Direct and indirect effects may make up causal connections between variables. Effects that flow directly from one variable to another are referred to as direct causal effects. When one or more factors mediate the link between two variables, indirect effects result.

The amount of time Jim spent on the bicycle is 6.5 hours.

The complete movement of an object, regardless of direction, is referred to as distance. The amount of ground a thing travels from its starting point to its destination is also referred to as distance.

Given:

Total distance, d = 255 miles,

Total time, t = 7 hours,

The speed of walking, s = 3 miles / hour,

The speed of riding bicycle, S = 39 miles/hour,

Calculate the time spent on the bicycle as shown below,

Total time = Time on bicycle + Time walking

7 = Distance on bicycle/speed + Distance of walking / speed

7 = b / 39 + w / 3

Here w is the distance by walking and b is the distance covered by bicycle,

b + w = 255 (As given)

Solve both equations,

w = 1.5 miles and b = 255 - 1.5 = 253.5 miles

We have,

From the figure given we see that,

88 and y + 10 are corresponding angles.

88 = y + 10

y = 88 - 10

y = 78

Now,

3x - 7 and 2x + 18 are oposite angles.

In  a right angled triangle, the opposite and adjacent sides are the sides proportional to the two acute angles of the triangle.

In every triangle, the sum of angles is 180⁰.  In a right angled triangle, one of the angles is = 90⁰.

The side facing the right angle is called the hypothenuse side.

The sum of the other two angles is 90⁰. That each of the angles is acute angle.

The sides proportional to the acute angles are the opposite and adjacent.  

If an angle is given in one of the angle, the side proportional to the given angle is called the opposite while the other one is called the adjacent.
