The decimal point is the dot that separates the whole number from the fractional part of the number.

The decimal to the nearest hundredth exists 1.45.

Integer and non-integer numbers are often expressed using the decimal numeral system.

Decimals are a type of number in algebra that have a whole number and a fractional portion separated by a decimal point. The decimal point is the dot that separates the whole number from the fractional part of the number.

The term "decimal" refers to the base-10 number system, which is arguably the most widely used. The ten single-digit numbers that make up the decimal number system are 0 through 9, or just 1, 2, 3, 4, 5, 6, and 7. 10 is the number that follows 9. 20 comes follows the number 19, and so on.

Any decimal number is rounded to the nearest hundredth by the term "to the nearest hundredth.

Let the given equation be −2.45 − (−3.9)

= -2.45+3.9

simplifying the above equation, we get

= 1.45

Therefore, the decimal to the nearest hundredth exists 1.45.

The complete question is:

Find -2.45-(-3.9). Write your answer as a decimal to the nearest hundredth.

Answer:

The distance is 280 miles

Step-by-step explanation:

Given

When going to the mountain:

Let the speed be x.

[tex]Speed = x[/tex]

[tex]Time = 8[/tex]

When going home:

[tex]Speed = 21 + x[/tex]

[tex]Time = 5[/tex]

Required

Determine the distance of the mountains

Distance is calculated as:

[tex]Distance = Speed * Time[/tex]

When going to the mountains, the distance is:

[tex]Distance = x * 8[/tex]

When going home, the distance is:

[tex]Distance = (21 + x) * 5[/tex]

It should be noted that, the distance is the same.

So, we have:

[tex]x * 8 = (21 + x) * 5[/tex]

Open bracket

[tex]x * 8 = 21* 5 + x * 5[/tex]

[tex]8x = 105 + 5x[/tex]

Collect Like Terms

[tex]8x - 5x= 105[/tex]

[tex]3x= 105[/tex]

Divide both sides by 3

[tex]x= \frac{105}{3}[/tex]

[tex]x= 35[/tex]

Substitute 35 for x in

[tex]Distance = x * 8[/tex]

[tex]Distance = 35 * 8[/tex]

[tex]Distance = 280[/tex]

The distance is 280 miles

Answer:

x = 6

Step-by-step explanation:

AC = 5x - 24

AO = 3

AC and BD bisect each other at point O. This means AC ≅ CO.

So, 2(AO) = AC.

2(3) = 5x - 24

Multiply.

6 = 5x - 24

Combine the constants.

30 = 5x

Divide by 5.

x = 6

Answer:

5 percent is the difference between 10 and 5 because the ramp needs to be 5 percent but most average wheelchair ramps are 10 degrees and there is a 5 degree differance

Step-by-step explanation:

hope this helps

Answer:

5° is the difference

Step-by-step explanation:

One of the ramps is 5° and the other one is 10°. The difference between these 2 ramps is of 5°.

10 - 5 = 5

And as you can see in the image, the mid ray is what divided both of the other rays, and its right in the middle. Both rays combined gives you 10° as it shows, and half of 10 is 5. So the difference will be of 5°

Answer:

x= 33.9

Step-by-step explanation:

use cosine because x is the adjacent and 40 is the hypotenuse

set up your equation:

cos(32)= (x/40)

multiply both sides by 40:

40(cos(32))= (x/40)40

40(cos(32))= x

multiply 40 by the cos(32):

33.9 = x

105x + 35y = 210

  -35x - 35y = -70

70x = 140

x = 2

-10 + 5y = 10

Answer:

57.8º

Step-by-step explanation:

According to the law of sines [tex]\frac{sinA}{a}[/tex] = [tex]\frac{sinb}{b}[/tex] = [tex]\frac{sinc}{c}[/tex].

In this triangle we have two sides with two of their angles.

Let's make 8 cm side a with 38º as its angle, and 11 cm side b with x as its angle.

[tex]\frac{sinx}{11}[/tex] = [tex]\frac{sin38}{8}[/tex]

Now we multiply both sides by 11 to get rid of the denominator on the left.

sinx = [tex]\frac{11sin38}{8}[/tex]

To find x, we use inverse sine.

x = sin⁻¹ (11sin38/8)

Plug this into a calculator, and you will get 57.837.

Round this to 57.8º
