Answer: 975

Step-by-step explanation:

PEMPAS (solve in this order):
1st solve what's in the parenthesis

2nd solve exponents

3rd solve Multiplication or Division from left to right

4th Add or Subtract from left to right

So:

(7.8)^1 * (5)^3 = 7.8 * 125

(because exponents means how many times a number multiplies by itself, in this case 5^3 is equal to 5*5*5 = 25*5 = 125)

7.8 * 125 =

975

Answer:

Part A:

8 x 7 = 56; 56 x 10 = 560

Part B:

504

Part A & B explanation:

If you notice, there are no decimals in the answers so it's clear they round them. 8.4 rounded is 8 & 6.9 rounded is 7. To find the area of a singular rectangle is length x width. 8 x 7 = 56. In part A the directions say "best estimate" signaling that it isn't the exact answer you're looking for. 8 x 7 = 56; 56 x 9 = 504 would be the exact answer. (Answer for part b).Therefore, the answer for part A is 8 x 7 = 56; 56 x 10 = 560. Because 560 is the closest to 504 on the board.

Answer:

10) c = 87.92

15) c = 272806.34

Step-by-step explanation:

10) radius = 14 in                 15) diameter = 86881 mi

c = ℼ × 2 × r                          c = ℼ × d

c = 3.14 × 2 × 14                   c = 3.14 × 86881

c = 87.92                              c = 272806.34

Answer:  13.65

Step-by-step explanation:

Answer:it’s 4 units to the left

Step-by-step explanation: The point (4,3) reflected the x-axis,

=> The x remains the same, the y flips over the x-axis to be negative

     (4,3) ==>> (4,-3)

The point (-3,-8) is reflected in the y-axis.

=> The y remains the same, the x flips over the y axis to be negative

     (-3,-8)==>>(3,-8)

The point (2,4) is reflected in the line x = -3.

=> The x remains the same, the y flips over the x= -3 line.

     Instead of reflecting over the x-axis (or the x = 0) line

     and just being +4 or 4 above the x-axis to -4 or 4 below the x-axis-axis-axis

     you have +4 being 7 above the x= -3 line so you need

     7 below the x= -3 line or -10  SO

      (2,4)==>>(2,-10)

The point (a, b) is reflected in the line y = x

     Consider that the line x=y is a 45-degree diagonal.

     Imagine a point on the 45-degree at +3  i.e. (3,0)

     Imagine a line perpendicular to x=y from the point (3,0)

           (sorry there is no way to draw on here - try drawing it)

    The line would hit the x-axis-axis at (0,3)

    So you can see the x becomes y and y become x.

     (a,b)==>>(b,a)

For

ΔXYZ is defined by its vertices X(1,3), Y(-3,5), and Z(0, -5).

       ΔXYZ is reflected in the y-axis.

So for each of the 3 points X, Y, and Z reflect about

       the y-axis the same way in the second example above

       and you will have the 3 new points X’,  Y', and Z’

The translation T: (x, y) → (x -2, y + 4) maps the point (2, -3) to

The translation T: (x, y) → (x + 3, y - 2) maps the point (-4, -3) to

     What you need to do here is just plug the values for X and Y into the translation.

     e.g. for T: (x, y) → (x -2, y + 4)  plug (2,-3) of x=2 y=-3 into (x -2, y + 4) and get the new values.

Answer:

2. 14 and 42

i hope it's right :)

Step-by-step explanation:

Let the number be x

So, the larger number = 3x

So the # is 14

The ages of John and Sam are 47.34 and 17.66 years respectively.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, John’s age is 12 more than 2 times Sam’s age. The sum of their ages is 65.

Let, The age of Sam be 'x'.

Therefore, 2x + 12 + x = 65.

3x = 53.

x = 17.66.

So, Sam is 17.66 years old and john is (65 - 17.66) = 47.34 years old.

Answer:

y = 3x - 6

Step-by-step explanation:

We have to write it in slope-intercept form, y = mx + b

m = slope, which is 3

y = 3x + b

b = y-intercept, which is (-6)

y = 3x + (-6), BUT that's not the proper way to write it.

The proper way to write it would be y = 3x - 6

Answer: 37

Step-by-step explanation:

4 x 9 = 36
