Answer: C) 4

The four signs are

<  which is a "less than" sign

> which is a "greater than" sign

[tex]\le[/tex] which is a "less than or equal to" sign

[tex]\ge[/tex] which is a "greater than or equal to" sign

Answer:

C) four

Step-by-step explanation:

to mark an inequality you have

less than (<),

greater than (>)

less than or equal (≤)

greater than or equal (≥)

and the not equal symbol (≠) but I assume your teacher didn't count this one for this question so just go with four :D

Answer:

Mira

Step-by-step explanation:

Rhona runs a measly 6 mph, nd Mira runs about 1.3. You gotta divide 8 by 6.

OR,

u can make common denominators. Make Rhona's 1 hour 6 hours, then multiply 6 by 6. Therefore, in 6 hours, Rhona runs 36 miles.

Answer:

40.

Step-by-step explanation:

Answer:

-20

Step-by-step explanation:

First, you just have to take off the negative sign:

[tex]5 \times 4[/tex]

Then, multiply:

[tex]5 \times 4 = 20[/tex]

Lastly, put the negative sign back on the 20:

[tex]-20[/tex]

That's your answer!

Answer:

Step-by-step explanation:

1) 24+P=56

You then would subtract 24 from the left and move it to the 56 side of the equation.

2)P=56-24

You then take 56-24=32.

3) P=32

Answer:

It would be 12 hours for the plane to go from a city to another/the other city

Step-by-step explanation:

(Distance=speed x time, Speed =distance ÷ time and Time =distance ÷ speed)

If you would apply the formula for time then

7,200m ÷ 600m/h = 12 hours

The plane flying at 600 miles per hour can cover a distance of 7200 miles in 12 hours.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, The distance between 2 cities is 7,200 miles and a plane can fly 600 miles per hour.

∴ The time required to cover the distance of 7200 miles is,

= (7200/600) h.

= 72/6 h.

= 12 h.

Answer:

  x = 20

Step-by-step explanation:

The sum of the given angle expressions is 90°, the measure of the right angle:

  x + (3x +10) = 90

  4x = 80 . . . . . . . . . subtract 10

  x = 20 . . . . . . . . . . divide by 4

Answer:

x = 20

Step-by-step explanation:

Key skills needed: Complementary Angles, Equations

1) We are given this diagram and we want to find out x.

The 2 angles (One with the measure "x degrees" and the other with the measure of "3x+10") are complementary. This means that both their measures add up to equal the measure of a right, or 90 degrees.

2) This means we can make the equation --> [tex]x + 3x + 10 = 90[/tex]

To solve:

Combine like terms (3x + x = 4x) --> [tex]4x + 10 = 90[/tex]

To get "x" by itself, subtract 10 from both sides (90 - 10 = 80)

This means it would be --> [tex]4x = 80[/tex]

Divide by 4 from both sides (80 divided by 4 is 20) and get x = 20

Therefore 20 is your answer.

Answer:

This is like asking x/-x = -1, where x∈N.

No matter what number you choose that is a nonzero number, negative or positive when divided by its negated self will always be -1. Therefore this statement is always true.

Answer:

1 1/4 ft

Step-by-step explanation:

First lets convert the fractions to decimals so it will be easier to divide. We need to divide to know how many leftover pieces of wood are there. 11.25 (11 1/4) divide by 2.5 (2 1/2) is 4 with the reminder of 1.25. So there are 4 (2 1/2 ft) wood pieces and 1 1/4 ft leftover piece of wood.

Answer:

Step-by-step explanation:

Answer:

y = 4 [tex](2)^{x}[/tex]

Step-by-step explanation:

For an exponential function in standard form

y = a [tex](b)^{x}[/tex]

To find the values of a and b, use ordered pairs from the table

Using (0, 4 ), then

4 = a[tex]b^{0}[/tex] ( [tex]b^{0}[/tex] = 1 ), so

a = 4

y = 4[tex]b^{x}[/tex]

Using (1, 8 ), then

8 = 4[tex]b^{1}[/tex] = 4b ( divide both sides by 4 )

2 = b

Thus

y = 4 [tex](2)^{x}[/tex] ← exponential function
