Answer:

Daniel = 207 | Brandon = 196.2

Step-by-step explanation:

Brandon will reach the taco truck first.

• Daniel's time can be found by using the expression 327.6/3 + 489/5, which is 207 seconds.

• Brandon's time can be found by using the expression

327.6^+489^2/3 [Sqaured]

The time taken by Brandon will be 196.2 seconds while Daniel will be 207 seconds.

A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.

In a triangle, the sum of all three angles is 180°.

⊕ Time is taken by Brandon ;

      01) Time taken in sand

             Time = 327.6/3 = 109.2 seconds.

     02) Time is taken on the boardwalk

             Time = 489/5 = 97.8 seconds.

Total time taken by Brandon = 109.2 + 97.8 = 207 seconds.

⊕ Time is taken by Daniel;

         By Pythagoras theorem

         Distance by Daniel = √(327.6² + 489² ) = 588.60 feets.

        Time = 588.60/3  = 196.2 seconds.

So the time taken by Brandon will be 207 seconds and Daniel will be 196.2 seconds.

Answer:

1)1920 in2  (2)120 in3

Step-by-step explanation:

Answer:

The answer is "Option A and Option B".

Step-by-step explanation:

In question 1:

In all cases, the entire population is measured so that the actual medium discrepancy could be measured as well as an interval of trust cannot be used.

This issue would be that she calculated the ages with all representatives of both classes, such that she measured a whole population. It's not necessary.

In question 2:

When the p-value is 0.042. At 90% trust and 92% trust level 11 (p-value below 0.10 and 0.08) are not included. however the biggest confidence level of 92%. Consequently, the largest trust level where the 11 is Not included in the trust interval is 92% trust.

Answer: x=12dm

Step-by-step explanation:

c=13     means hypotenous

a=5     means altitude

b=x=?   means   base

By pythagorean theorem

c^2=a^2+b^2

(13)^2=(5)^2+(x)^2

169=25+x^2

x^2=169-25

x^2=144

Taking sqrt  on both sides

Answer:

  C. 3√2 units

Step-by-step explanation:

The diagonal of a square is √2 times the side length. For a square with side length 3, the diagonal is 3√2.

__

If you like, you can see this using the Pythagorean theorem.

  d² = s² + s² . . . . . where d is the diagonal, and s is the side

  d² = 2s²

  d = √(2s²) = s√2

For s=3, ...

  d = 3√2

Answer:

Step-by-step explanation:

The outside diameter minus the inside diameter would leave a difference of TWICE the thickness of the pipe, so divide the difference by 2

Pipe Thickness =  (OD -  ID) / 2  

                           =  (1.275 - 0.975) / 2

                           =   0.3 / 2

Answer:

thhhhhhheeeeeeeee p.m.f of x

Answer:

Step-by-step explanation:

4(3x-5)^2+5=13

4(3x-5)^2+5-13=0

As  (a-b)^2=a^2-2ab+b^2

4((3x)^2-2(3x)(5)+(5)^2)-8=0

4(9x^2-30x+25)-8=0

36x^2-120x+100-8=0

36x^2-120x+92=0

using the Quadratic Formula where

a = 36, b = -120, and c = 92

x=(−bc± sqrt(b^2-4ac))/2a

x=(-(-120)±sqrt((−120)^2−4(36)(92))/2(36)

=120±sqrt(14400−13248−)/72

=120±sqrt(1152)/72

The discriminant b2−4ac>0

so, there are two real roots.

x=(120±24sqrt(2))/72

x=(120/72)±24sqrt(2)/72

implify fractions and/or signs:

x=5/3±sqrt(2)/3

Answer:

No, the diagonals of a rectangle are not parallel.

In fact, they intersect at a point, so that means it is impossible for them to be parallel.

Answer:

This depends on the situation. For context, you use less than when your inequality CANNOT exceed more than.

You would use less than or equal to if your inequality can be equal to a number. Here's an example.

John needs to buy X oranges and Y apples. He can AT MOST buy 10 total fruits.

x + y (equal to or less than) 45

John needs to buy X oranges and Y apples. He CANNOT buy more than 10 total fruits.

Answer:

The two lines are not parallel.

Step-by-step explanation:

Every linear equation follows this structure:

y = mx + b

y is the y value

x is the x value

m is the gradient/slope of the line

b (or sometimes c) is the y-intercept of the line

Firstly, we have to get the y term on one side by itself.

6x + y = -1

-6x        -6x

y = -6x - 1

-2x -5y = 1

+2x         +2x

-5y = 2x + 1

Secondly, we make it so the y term is just the y value.

The first equation is already like this, so we don't need to do anything to that.

-5y = 2x + 1

÷ -5  ÷ -5

y = (2x + 1) / -5

This can be expanded and simplified to:

y = -2/5x - 1/5

Thirdly, we have to compare the slopes and y-intercepts.

y = -6x - 1

y = 2/5x - 1/5

If the slopes are the same and the y-intercepts are different, they are parallel. However, the slopes are different, therefore they are not parallel.
