Answer:

40 ÷ 1

Step-by-step explanation:

Speed = Distance : Time

Speed = 40 ÷ 1

Answer:

(you'll have to read the explanation)

Step-by-step explanation:

There are 8 lines from 1 to 2, so plotting 1 1/2 (or 1.5) is right in between. I'm not sure how to add the picture back into the explanation, but I will try my best to explain. You want to plot your point for 1 1/2 4 lines after the 1. For the 2 1/4, you want to plot your point on the second line from the 2. Let me know if it doesn't make sense!

Answer: See the attached image below

1 1/2 is located at the exact midpoint between 1 and 2.

2 1/4 is located 2 tickmarks to the right of 2.

===================================================

Explanation:

Think of 1/2 as 4/8

The number 1 1/2 is the same as 1 4/8

So we start at 1 and move 4 tickmarks to the right to get at the exact midpoint (note there are 8 tickmarked spaces between any two whole numbers).

This places us exactly at the midpoint between 1 and 2.

-----------------

To plot 2 1/4, we will effectively plot 2 2/8 since 1/4 = 2/8

We start at 2 and then move 2 tickmarks to the right to arrive at 2 2/8

Answer:

-1 < -0.25

Step-by-step explanation:

-1 is less than -0.25

less than symbol = <

greater than symbol = >

Example; -1 > -2 --- negative one is greater than negative two OR -2 < -1 --- negative two is less than negative one

Answer:

-1<-0.25

Answer:

{a , c}

Step-by-step explanation:

first find u intersection p

n(U n P ) = {a , b , c , d} n {b , d , e}

={d , b}

intersection means element or values which lies in both the sets

now to find p complement

note : p( bar at the top ) is read as p complement

p complement = n(U) - n(U n P)

={a , b , c , d} - {d , b}

={a , c}

n(U) -n(U n P) means the elements which is only in n(U ) but not in n(U n P)

Answer:

a,c

Answer:

8 = x

or

x = 8

Step-by-step explanation:

x – 3 = 5

x + -3 + 3 = 5 + 3

x = 5 + 3

(5 + 3 = 8)

x = 8

Answer:

x=8

Step-by-step explanation:

x-3=5

x-3+3=5+3

x=8

Answer:

700 cubic inches

Step-by-step explanation:

The question asks for how much volume the box can hold. We multiply the length (14), width (10), and height (5) to get the volume. 14 · 10 · 5 = 700.

The box can hold 700 cubic inches.

Answer:

16b^4-9

Step-by-step explanation:

Factoring gives us 16b^4+12b^2-12^2-9. Simplifying gives us the answer which is 16b^4-9

Answer:

[tex]16b^4-9[/tex]

Step-by-step explanation:

When multiplying binomials, we can use a method called FOIL (First-Outside-Inside-Last).

For [tex](t_1+t_2)(t_3+t_4)[/tex], let:

[tex]t_1\implies \text{First Term},\\t_2\implies \text{Second Term},\\t_3\implies \text{Third Term},\\t_4\implies \text{Fourth Term}[/tex]

In the FOIL method, the steps go:

[tex]\text{\textbf{F}irst: Multiply the first and third terms (first term of each binomial)},\\\text{\textbf{O}utside: Multiply the first and fourth terms},\\\text{\textbf{I}nside: Multiply the second and third terms},\\\text{\textbf{L}ast: Multiply the second and fourth terms (last term of each binomial) }[/tex]

Given [tex](4b^2+3)(4b^2-3)[/tex], we have:

[tex]\text{First: }4b^2\cdot 4b^2,\\\text{Outside: }4b^2\cdot -3,\\\text{Inside: }3\cdot 4b^2,\\\text{Last: }3\cdot -3,\\\rightarrow 16b^4-12b^2+12b^2-9[/tex]

Combine like terms:

Answer:

90

Step-by-step explanation:

900 in groups of 10 would need 90 groups to equal 900.

Answer:

90

Step-by-step explanation:

We also have 9 tens, which means we can say 9×10=90. And we have 24 ones, which means we can say 24×1=24.

Answer:

x-1

Step-by-step explanation:

Area= x^2+4x-5

Width= x+5

Area= Length*breadth

x^2+4x-5=length*x+5

Length=x^2+4x-5/x+5

Therefore, length= x-1

Answer:

x-1

i got this problem on khan academy

Answer:

25.12

Step-by-step explanation:

the formula of a cone is pi r^2 * h/3

r = radius and h = height

the radius is 2 and the height is 3

and the question says use 3.14 instead of pi so

we have

3.14 * 2^2 * 6/3

2*2 or 2^2 = 4

3.14 * 4 * 6/3

6/3 = 2

3.14 * 4 * 2

4*2 = 8

and 8 * 3.14 is 25.12

8 TEACHERS

4 MALES 4 FEMALES

4 ARE GONE SO 2 MALES LEFT 2 FEMALES LEFT =4 TEACHERS

Answer:

short base: 6 yards

long base: 8 yards

Step-by-step explanation:

Our understanding of your figure is shown below.

The question says the "shortest side" and the "width" have the same dimension. If the "width" is a reference to "height 6 yards", then it seems the "shortest side" is 6 yards. Since the slant sides are longer than the height, the "shortest side" is also the "short base."

The short base is 6 yards.

__

The long base overhangs the short base by 1 yard on either end, so it is a total of 2 yards longer than the short base. It it 6+2 = 8 yards long.

The long base is 8 yards.

Hope this is correct, if not then feel free to let me know. I'm sorry in advance if it is incorrect.

Answer:

6 2/3 = x

Step-by-step explanation:

24 1/14 + 8 3/7  = (x ÷ 1 1/9) * 5 5/12

Add on the left by getting a common denominator

24 1/14 + 8 3/7*2/2  = (x ÷ 1 1/9) * 5 5/12

24 1/14 + 8 6/14  = (x ÷ 1 1/9) * 5 5/12

32 7/14  = (x ÷ 1 1/9) * 5 5/12

32 1/2 =  (x ÷ 1 1/9) * 5 5/12

Changing to improper fractions

(2*32+1)/2 = (x ÷ 10/9) * (12*5+12)/12

65/2 = (x ÷ 10/9) * (65)/12

Multiply each side by 12/65

65/2 * 12/65 = (x ÷ 10/9) * (65)/12*12/65

6 = (x ÷ 10/9)

Copy dot flip

6 = x * 9/10

Multiply by 10 /9

6 * 10/9 = x * 9/10 * 10/9

60/9 =x

20/3 =x

Changing back to a mixed number

3 goes into 20 6 times with 2 left over

6 2/3 = x

Answer:

[tex]\frac{20}{3}[/tex]

Step-by-step explanation:

[tex](24+8)+(\frac{1}{14} +\frac{3}{7})=(x:\frac{10}{9}).\frac{65}{12}\\32+\frac{1}{2}=(x.\frac{9}{10}) .\frac{65}{12} \\32\frac{1}{2}=(\frac{9}{10}x).\frac{65}{12} \\\frac{65}{2}=\frac{9}{10}x.\frac{65}{12} \\\frac{65}{2}=\frac{3}{2} x.\frac{13}{4} \\\frac{65}{2} =\frac{39}{8} \\\frac{20}{3} =x\\x=\frac{20}{3}[/tex]
