Step-by-step explanation:

Actual length of the Bridge = 8983.33 feet.

The scale is 1 unit = 19,600.

Height of the postcard is 3.5 inches.

So, original height of the bridge = 3.5 × 19,600 = 68,600 inches

= 5716.67 feet

Width of the postcard is 5.5 inches.

So, original width of the bridge = 5.5 × 19,600 = 107,800 inches

= 8983.33 feet

hope it helps

The correct option is (c) 8980 feet.

               length of the Bridge = 8983.33 feet.

                The scale is 1 unit = 19,600.

                Height of the postcard is = 3.5 inches.

So,

     Original height of the bridge = 3.5 × 19,600 = 68,600 inches

                                                       = 5716.67 feet

Width of the postcard is 5.5 inches.

So, original width of the bridge = 5.5 × 19,600 = 107,800 inches

                                                     = 8983.33 feet

Therefore, the original width of the bridge is 8983.33 feet .

You have to multiply to get a simple equation so it would be 15x+45=15x-2x+10 and that’s where my knowledge stops with that

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

Let's solve your equation step-by-step.

5 ( 3x + 9 ) − 2x = 15x − 2 ( x − 5 )

Step 1: Simplify both sides of the equation.

5 ( 3x + 9 ) − 2x = 15x − 2 ( x − 5 )

( 5 ) ( 3x ) + ( 5 ) ( 9 ) + −2x = 15x + ( −2 ) ( x ) + ( −2 ) ( −5 ) ( Distribute )

15x + 45 + −2x = 15x + −2x + 10

( 15x + −2x ) + ( 45 ) = ( 15x + −2x ) + ( 10 ) ( Combine Like Terms )

13x + 45 = 13x + 10

13x + 45 = 13x + 10

Step 2: Subtract 13x from both sides.

13x + 45 − 1 3x = 13x + 10 − 13x

45 = 10

Step 3: Subtract 45 from both sides.

45 − 45 = 10 − 45

0 = −35

Step-by-step explanation:

(((2•3x2) • y2) -  9xy) -  42

6x2y2 - 9xy - 42  =   3 • (2x2y2 - 3xy - 14)

The complete factorization of 6x^2y^2-9xy-42 is 3 (2x^2y^2 - 3xy - 14).

factorization is the method of breaking a number into smaller numbers that multiplied together will give that original form.

The given expression is

[tex]6x^2y^2-9xy-42[/tex]

= [tex](((2\times3x^ 2) \times y^2) - 9xy) - 42[/tex]

The factorized form will be

Answer:

3,21 is

2,21 is not a proper ordered pair.

Step-by-step explanation:

Remark

It's not a solution

You can either use the x value to find out the proper y value

or

You can use the y value to find out the proper x value

Proper y value

Let x = 2

y = 7*2

y = 14

So the proper y value given that x = 2 is 14.

Proper x value

Let y = 21

21 = 7x                    Divide both sides by 7

21/7 = 7x/7

3 = x

But (2,21) is not a solution. (3,21) is.

Answer:

rotation of 90° counterclockwise, then translation 3 down

The given figure has a rotation of 90° counterclockwise, then translation 3 down.

A translation moves a shape left, right, up, or down without turning it. The translated (or picture) shapes appear to be the same size as the original shape, showing that they are congruent. They've just moved in one or more directions.

The two figures given in the image are plotted on the coordinate plane having axis x and y.

From the figure it is observed that the given figure has a rotation of 90° counterclockwise, then translation 3 down.

Therefore, the given figure has a rotation of 90° counterclockwise, then translation 3 down.

Step-by-step explanation:

Since there are 4 donuts in each box, and 76 boxes total, then you know that you need to divide the number of donuts by the amount of donuts in each box. b= 19 if u needed that. Cheers

Answer:

The answer is 19 boxes

Since there were 4 donuts in each box all you have to do is divide 76 by 4 since there is 76 donuts in all 76 ÷ 4 = 19 boxes (79 equally distributed into 19 boxes)

Answer:

CI= [4.324 , 5.6758]

Step-by-step explanation:

The 90 % confidence interval for the normal distribution is given by

(x`1- x2` ) ± t ∝/2 (υ) .Sp √1/n1 + 1/n2

where Sp = √[n1-1 (s1)² + n2-1 (s2)²]/n1+n2-2

and n1= 12 n2=10

x1`= 16 km x`2 = 11km

s1= 1km s2= 0.8km

and degrees of freedom υ= n1+n2-2= 20

Here ∝/2 = 0.05

From the table we get the value of t∝/2 (υ) to be 1.725

Putting the values

Sp = √[n1-1 (s1)² + n2-1 (s2)²]/n1+n2-2

Sp= √11(1) + 9(0.8)²/20

Sp= √0.838=0.915

CI = (x`1- x2` ) ± t ∝/2 (υ) .Sp √1/n1 + 1/n2

CI = (16-11)± 1.725 * 0.915√1/12+ 1/10

CI = (5) ± 0.675819

CI=[ 4.324 , 5.6758]

Answer:

Step-by-step explanation:

You have to use the arithmetic sequence

f(n)=f(n-1)+d

You can plug in (40,10) and (50,20)

(10)=f(1)+39d

(20)=f(1)+19d

subtract

-10=20d divide

d=-1/2

plug into one of the equations above

(10)=f(1)+39(-1/2)

10=f(1)-39/2

59/2=f(1)

f(1)=29.5

plug into formula

f(n)=29.5-1/2(n-1)

f(n)= -1/2n +30 final equation (Plug in the table values into "n") to solve

Answer:

i think 20%

Step-by-step explanation:

The percent increase of the salary is 25%.

We have,

the salary increases from $12,000 to $15,000

So, Change in Amount= (15,000 - 12,000)

= 3, 000

Now, Percent increase = change in amount/ original amount x 100

= 3000/ 12000 x 100

= 1/4 x 100

= 100/4

= 25%

Thus, the percent increase is 25%.

Answer: 6 meters

Step-by-step explanation:

I had this question and got the answer right.

The distance from the base of the tree will be 6 meters.

The Pythagorean theorem says that the sum of the square of the perpendicular and the base will be equal to the square of the hypotenuse of the right-angle triangle.

Given that a bird is perched eight meters up in a tree. The bird is 10 meters away from you where you are standing.

From the Pythagorean theorem, the base will be calculated as:-

H² = P² + B²

B = √ ( H² - P² )

B = √ ( 10² - 8² )

B = √36

B = 6 meters

Hence, the 6 meters will separate you from the tree's base.
