)A scanner scanned 63 photos in 9 minutes. If it scans photos at a constant rate, it can scan _____ photos in 21 minutes.

Answer:

B: 24ft^2

Step-by-step explanation:

Area of triangle = (base x height)/2

Step 1: form an equation

a = (12ft x 4ft)/2

Step 2: solve equation

a = 48ft^2 / 2

a = 24ft^2

*the base is the measurement for the bottom of a triangle while height is the measurement of the length from the bottom to the top of a triangle*

Answer: 5-lb bag for $12.99

Answer:

9,027.83

100 times smaller

Step-by-step explanation:

Given 184.36, the place value of 8 in the number is 8 tens i.e 8* 10 = 80

The place value of 8 in 9,027.83 is 8 tenth i.e 8* 1/10

8* 1/10 = 8/10

8/10 = 0.8

Hence the number that has the smaller value of 8 is 9,027.83.

To get how many times smaller the number is, we will take the ratio of 80 to 0.8 as shown:

[tex]= \frac{80}{0.8}\\ \\= 80 \div 0.8\\\\= 80 \div \frac{8}{10} \\\\[/tex]

[tex]= 80 * \frac{10}{8}\\ \\= \frac{800}{8}\\ \\= 100[/tex]

This means that the number 0.8 is 100 times smaller than 80

Answer:

Step-by-step explanation:

Let A and B represent the angles that PA and PB make with the horizontal, respectively. Let Ta and Tb represent the tensions in PA and PB, respectively. Then for equilibrium, we have ...

  Ta·cos(A) - Tb·cos(B) = 0 . . . . . horizontal equilibrium

  Ta·sin(A) +Tb·sin(B) = T . . . . . . where T is the downward force exerted by P

__

The general solution of this pair of equations is ...

  Ta = T·cos(B)/(sin(B)cos(A) +sin(A)cos(B)) . . . by Cramer's rule

which simplifies to

  Ta = T·cos(B)/sin(A+B)

  Tb = T·cos(A)/sin(A+B) . . . . by symmetry or Cramer's rule

If we call the position of the right angle point X, then the Pythagorean theorem tells us AX = 30 (3-4-5 triangle) and BX = 96 (5-12-13 triangle). Then the cable tensions are ...

  Ta = T·(12/13)/(12/13·4/5 +3/5·5/13) = T·(20/21)

  Ta = (2.1 kg)(9.8 m/s²)(20/21) = 19.6 N

  Tb = T·(3/5)/(63/65) = T·(13/21)

  Tb = (2.1 kg)(9.8 m/s²)(13/21) = 12.74 N

These tension values can be rounded to Ta = 20 N, Tb = 13 N.

_____

The weight of P is ...

  F = Ma = (2.1 kg)(9.8 m/s²) = 20.58 N

Answer: $171.31

Step-by-step explanation:

A = P(1 - r)ⁿ

Given: P = 200, r = 1.1% (.011), n = 14

A = 200(1 - .011)¹⁴

  = 200(.989)¹⁴

  = 171.308

Since we are talking about money, round to two decimal places.

Answer:

Should be the 2nd choice.

Answer:

a

 [tex]P(r n L) =  0.12[/tex]  

b

 [tex]P(L) = 0.225[/tex]

c

  [tex]P(\= r | L) = 0.4667 [/tex]

Step-by-step explanation:

The chance that it will rain is  [tex]P(r ) = 0.30 [/tex]

 The chance that it does not rain is [tex]P(\= r ) = 1 - P(r )  [/tex]

                                                             [tex]P(\= r ) = 1 -0.30  [/tex]

                                                              [tex]P(\= r ) = 0.70  [/tex]

The probability that the bus run late if it rains is  [tex]P(L | r) = 0.4[/tex]

 The probability that the bus run late if it does not rain is   [tex]P(L | \= r) = 0.15[/tex]

  Generally the probability that it will rain and the bus will be late is mathematically represented as

     [tex]P(r n L) = P(L | r) * P(r)[/tex]

=>  [tex]P(r n L) = 0.4 * 0.30[/tex]

=>  [tex]P(r n L) = 0.12[/tex]  

Generally the probability that the bus will be late is mathematically represented as

     [tex]P(L) = P(r) * P(L|r) + P(L | \= r) * P(\= r)[/tex]

=>  [tex]P(L) = 0.30 * 0.4 +0.15*0.70[/tex]

 =>  [tex]P(L) = 0.225[/tex]

Generally given that the bus ran late,  the probability that the bus it was not raining is mathematically represented as

      [tex]P(\= r | L) = 1- P(r | L )[/tex]

Here  [tex]P(r | L ) = \frac{P(r n L)}{P(L)}[/tex]

=>   [tex]P(r | L ) = \frac{0.12}{0.225}[/tex]

=>   [tex]P(r | L ) = 0.533 [/tex]

So

      [tex]P(\= r | L) =  1- 0.533[/tex]

   =>   [tex]P(\= r | L) =  0.467 [/tex]

No, the estimate of 11 × 2 = 22 tells us that 2.6509 is too small and the decimal point is placed incorrectly. The product has four decimal places and should have been 26.5090, but a missing zero on the end caused the decimal to end up in the wrong position.

Step-by-step explanation:

Answer:

40 units

Step-by-step explanation:

Given:

Perimeter of ∆ABC = 85 units

AC = 4z

AB = 3z + 3

BC = z + 2

Required:

Numerical value of AC

SOLUTION:

Perimeter of ∆ = sum of all its sides

Perimeter of ∆ABC = AC + AB + BC

85 = 4z + (3z + 3) + (z + 2)

Use this equation to find the value of the variable, z

[tex] 85 = 4z + 3z + 3 + z + 2 [/tex]

Collect like terms

[tex] 85 = 8z + 5 [/tex]

Subtract 5 from both sides

[tex] 85 - 5 = 8z [/tex]

[tex] 80 = 8z [/tex]

Divide both sides by 8

[tex] 10 = z [/tex]

[tex] z = 10 [/tex]

AC = 4z

Plug in the value of x

AC = 4(10)

AC = 40 units
