Is 0.30 greater than, less than,
or equal to 0.3?

9514 1404 393

Answer:

Step-by-step explanation:

In order for the total displacement to be zero, the amount of forward displacement must be equal and opposite to the amount of backward displacement. Since the steps are the same length, they must be equal in number.

Half of the 10 steps were forward, and the other half were backward.

  5 steps forward; 5 steps backward.

Additional comment

Math develops from an effort to model the real world. It would probably give you some insight into this problem if you were to physically take some steps to see how many forward and backward you would need to end where you start.

What is the probability of drawing a red card or a queen from a standard deck of 52 cards?

7 over 13

15 over 26

1 half

1 over 26

The probability for red card or queen is given as 15/26. The correct option is (B).

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lie in the close interval of 0 and 1 [0,1].

The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.

The total number of red cards in the deck is 26.

And, the number of queens in the deck is 4.

Now, the probability of getting red card is given as,

P(red cards) = Number of red cards ÷ Total number of cards

⇒ P(red cards) = 26/52 = 1/2.

Similarly, the probability of queen is,

P(queen) = 4/52 = 1/13

Thus, the probability of drawing a queen or red card is given as,

P(red card or queen) = P(red card) + P(queen)

⇒ P(red card or queen) = 1/2 + 1/13 = 15/26.

Hence, the probability of drawing a red card or a queen from a standard deck of 52 cards is 15/26.

Answer:

6 1/4 cups of flour

Step-by-step explanation:

24/2 = 12

2.5/2 = 1.25

12 x 5 = 60

1.25 x 5 = 6.25 cups

For every 24 cookies Markes needs 2.5 cups of flour. So, for 12 cookies he needs half of that which is 1.25 cups. 12 is a fifth of 60, so we multiply 1.25 by 5 which gives us 6.25 cups of flour. :D

Answer:

The water level would rise by [tex]5\; \rm cm[/tex].

Step-by-step explanation:

Assume that the initial water level is [tex]h\; \rm cm[/tex].

Before the cube was placed in the tank, the volume of the water was the same as the volume of a rectangular prism with a length of [tex]160\; \rm cm[/tex], a height of [tex]80\; \rm cm[/tex], and a height of [tex]h\; \rm cm[/tex]:

[tex]\begin{aligned} & 160\; {\rm cm} \times 80\; {\rm cm} \times h\; {\rm cm} \\ =\; & (80 \times 160) \, h \; \rm cm^{3} \end{aligned}[/tex].

Let the rise in the water level in the tank be [tex]x\; \rm cm[/tex]. The new water level would be [tex](x + h)\; \rm cm[/tex].

The volume of the water and the submerged cube, combined, would be the same as that of a rectangular prism with a length of [tex]160\; \rm cm[/tex], a width of [tex]\rm 80\; \rm cm[/tex], and a height of [tex](x + h)\; \rm cm[/tex]:

[tex]\begin{aligned} & 160\; {\rm cm} \times 80\; {\rm cm} \times (x + h)\; {\rm cm} \\ =\; & (80 \times 160) \, (x + h) \; \rm cm^{3} \end{aligned}[/tex].

In other words:

Therefore, the volume of the submerged cube could be expressed as:

[tex]\begin{aligned} & (80 \times 160) \, (x + h) \; {\rm cm^{3}} - (80 \times 160) \, h \; \rm cm^{3} \\ =\; &(80 \times 160)\, x\; {\rm cm^{3}}\end{aligned}[/tex].

On the other hand, the volume of the cube could be expressed as:

[tex](40\; \rm cm)^{3} = 64000\; \rm cm^{3}[/tex].

Equate these two expressions for the volume of the cube and solve for [tex]x[/tex], the rise in the water level in the tank:

[tex](80 \times 160)\, x = 64000[/tex].

[tex]x = 5[/tex].

In other words, the rise in the water level in this tank would be [tex]5\; \rm cm[/tex].

d

Answer:

2 by 25 feet.

Step-by-step explanation:

Let L and W be the length and the widht of the field

we want W = L + 23 and W x L = 50

So

(L + 23) x L = 50

[tex]L^2 + 23L = 50\\L^2+23L-50 =0\\(L+25)(L-2)=0\\L=-25 \text{ or } L = 2[/tex]

Since L must be positive then L =2 and W = 2 + 23 = 25.

Answer:

D

Step-by-step explanation:

First off, lets simplify (3-2^2)+5 = -1+5 = 4

We will need to  find an expression that will equal to 4

lets try 1, 5-2^2 = 1, 1 =\ 4

Alright, lets try 2, 2^2 -5 = -1, -1=\5

Now lets try 3, 5 - 3^2 = -4, -4=\4

So by process of elimination we can say that D is correct by I will show you why it is correct. 3^2 -5 = 4, 4=4

Answer:

3.25

Step-by-step explanation:

1 hong kong dollar = 0.13 cents in us dollars

0.13x25=3.25

The value of 25 Hong Kong dollars in U.S dollar is $3.1969

Given that :

$1 = 7.82 Hong Kong dollars

Let the equivalent Number of U.S dollars = p

This means that :

$1 = 7.82 Hong Kong dollars

$1 = 7.82 Hong Kong dollars $p = 25

Cross multiply :

25 × 1 = 7.82 × p

25 = 7.82p

Divide both sides by 7.82

25 / 7.82 = p

p = $3.1969

Hence, 25 Hong Kong dollars is 3.1969 U.S dollars.
