What is The difference of 3 and a number X

Answers

Answer:

"the difference of" means to subtract

Therefore, "the difference of 3 and a number" would be:

3-x

Step-by-step explanation:

The required number is 63 and its 20% will be 12.6.

What is the number system?

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9.

The difference between 3 and the number x of that number is -60.

According to the question, the algebraic form will be as:

⇒ 3 - x = -60

⇒ x = 60 + 3

Apply the addition operation,

⇒ x = 63

So the required number is 63

20% of the number = (20/100) × 63

20% of the number = (0.20) × 63

20% of the number is 12.6.

Therefore, the required number is 63 and its 20% will be 12.6.

Answer:

Triangle STU is not similar to Triangle VWU

Step-by-step explanation:

For two triangles to be similar, they both should have the same angle measures. To find out if they have the same angle measures, we have to solve for the unknown angles. Remember, a triangle is worth 180°.

Triangle STU:

x + 90 + 42 = 180x + 132 = 180x = 48

Triangle VWU:

x + 58 + 90 = 180x + 148 = 180x = 32

As you can see, the angles don't have the same angle measures. Thus, they are not similar.

What is the probability of selection?

We are told that;

There are 6 dessert options menu.

Now, Akira and Paula like all of the choices equally. Thus, probability of selecting any of the 6 menus will be; P(select 1 menu) = 1/6

Thus, probability that they select the preferred menu written in the question is; P(both select 1 menu) = 1/6 * 1/6 = 0.028

Answer:

Step-by-step explanation:

Because supplementary angles are either 2 angles where the sum equals 180, if we take 60 for [tex]\angle {1}[/tex], and then add it to [tex]\angle {2}[/tex], we get 2(60) = 120 for [tex]\angle 2[/tex] and 60 for [tex]\angle 1[/tex], meaning that if we add the values of both angles together, it will be 120 + 60 = 180.

At a particular school 20% of children travel by bus.
If this represents 280 children, how many children attend the school?

Answers

Answer:

1,400 children attend the school

Step-by-step explanation:

If 20% is 280, we can set up a proportion to solve for how many attend the school. I will put the percentages on top and the number of children on the bottom:

-> Please note that a percentage divided by 100 becomes a decimial

[tex]\frac{20}{280}=\frac{100}{x}[/tex]

Cross multiply:

.2 * x = 280 * 1

.2x = 280

Divide both sides of the equation by .2:

1,400 children attend the school

We can check our work by multiplying 1,400 by 0.2:

1,400 * 0.2 = 280 ✓

During his leg of the run, Shannon developed hypothermia, a dangerous condition caused by extreme cold. Normal body temperature is 98.5ºF. During hypothermia, it falls by at least 3.5º. If his temperature dropped by that amount, what was Shannon’s body temperature with hypothermia?

Answers

Normal body temperature
= 98.5 °F
Temperature falls by 3.5 °F during hypothermia
Hence there is a decrease in the normal temperature

Therefore the temperature during hypothermia
= 98.5 -3.5
= 95 °F
