Answer:

≈ 125.3

Step-by-step explanation:

If we're using the Pythagorean Theorem to solve this, then the formula is:

[tex]a^{2}+ b^{2} =c^{2}[/tex]

So basically, by using this formula, you're finding the length that the soccer players will run diagonally. Plug in the numbers:

[tex]110^2 + 60^2 = c^2[/tex]

12100 + 3600 = [tex]c^2[/tex]

15700 = [tex]c^2[/tex]

Take the square root:

15700 = [tex]c^2[/tex]

[tex]\sqrt{15700} = \sqrt{c^2}[/tex]

125.3 ≈ c

Answer:

event A and B are independent because  P(A and B)  = P(A) x P(B) = 0.15

Step-by-step explanation:

When two events are independent, the probability of both occurring is the product of their separate probabilities, as expressed below;

P(A and B)  = P(A) x P(B)

Given;

P(A) =  0.25

P(B) = 0.60

P(A and B) = 0.15

Now, let's check if  P(A and B) will be equal to P(A) x P(B)

P(A) x P(B) =  0.25 x 0.60 = 0.15

P(A and B)  = P(A) x P(B), thus event A and B are independent.

Answer:

the answer to the question is D

Answer:

Option A,$320.98  is correct

Step-by-step explanation:

The new balance on Elijah's credit is the sum of the last balance plus new charges minus payments made.

last balance as shown by the statement was $152.58

new charges were $213.40

payment made by Elijah was  $45

new balance=$152.58+$213.40-$45=$320.98

The rationale for this is that the new charges on the card account add to previous balance owed by Elijah while the payment of $45 made reduces overall balance.

Answer:

Other answer is incorrect. Elijah's new balance would be $322.59

The terms that are interchangeable are axioms and postulates.

"In mathematics or logic, an axiom is an unprovable rule or first principle accepted as true because it is self-evident or particularly useful. “Nothing can both be and not be at the same time and in the same respect” is an example of an axiom"

"The term is often used interchangeably with postulate, though the latter term is sometimes reserved for mathematical applications (such as the postulates of Euclidean geometry). It should be contrasted with a theorem, which requires a rigorous proof."

By the definition of Axiom and postulates,

It is clear that Axiom and postulates are interchangeable, since they both used as a unprovable rule.

Hence A is the correct option.

Answer: One large pizza with a radius of 12 inches

Step-by-step explanation:

Hi, to answer this question we have to calculate the area of each option.

Area of a circle: π r^2  

A = π r^2 = π 6^2 = 113.1 in2

Since there are 2 small pizzas we have to multiply the area by 2:

113.2 x 2 = 226.2 in2

A = π r^2 = π 12^2 = 452.38 in2

Since 452.38 in2 > 113.1 in2

Option 2 (one large pizza) will give her more square inches of pizza

Step-by-step explanation:

Any smooth curve connecting two points is called an arc. The length of arc s to the nearest tenth is 10.5 in.

Any smooth curve connecting two points is called an arc. The arc length is the measurement of how long an arc is. The length of an arc is given by the formula,

[tex]\rm{ Length\ of\ an\ Arc = 2\times \pi \times(radius)\times\dfrac{\theta}{360} = 2\pi r \times \dfrac{\theta}{2\pi}[/tex]

where θ is the angle, which arc creates at the center of the circle in degree.

The length of the given arc s, with an angle made at the center equal to (2/3)π and radius of 5 inches can be represented as,

[tex]\text{Length of Arc} = 2\pi r \times \dfrac{\theta}{2\pi}[/tex]

[tex]\text{Length of Arc s} = 2\pi \times (5)\times \dfrac{\frac23\pi}{2\pi}[/tex]

                        [tex]=10.472\approx 10.5\rm\ in[/tex]

Thus, the length of arc s to the nearest tenth is 10.5 in.

Answer:

x=20 and y=128.Option 2

Step-by-step explanation:

Since,the angles are vertically opposite,they are equal(property)

Therefore,

(3x-8)=(2x+12)

3x-8=2x+12

3x-2x=12+8

x=20,

Now,

Since,the angles are formed in a straight line,their sum is equal to 180(property)

Therefore,

y+(2x+12)=180

y+2×20=180-12

y=168-40

y=128

Therefore,x=20 and y=128

option 2 would be your answer because it explains the missing part where y is.

Answer:

B.) 7

Step-by-step explanation:

7 x 4 = 28

28 + 12 = 40

:)

Using multiplication, the original number is 7.

Multiplication is "the process multiplying that the integer is multiplied by number of time".

According to the question,

A number is multiplied by 4. The results is added to 12. The final number is 40. In order to find original number.

4x + 12 = 40

        4x = 40 -12

        4x = 28

          x = 28/4

          x = 7.  

Hence, using multiplication, the original number is 7.
