Answer:

  a) the distributive property

  b) Yes

Step-by-step explanation:

a) The distributive property of multiplication over addition tells you ...

  a(b+c) = ab +ac

James has a=3, b=8, c=7, so he can fill in the values to get ...

  3(8+7) = 3·8 +3·7

Taking this one step into the evaluation, James gets ...

  3(3+7) = 3·8 +3·7 = 24 +21 . . . . . . the result James reports

___

b) Our result agrees with James' result, so we agree with James.

Help me please. I'm very confused

To solve this problem we must find 5% of 1418 and 4% of 1418
which is
5 \div 100 \times 1418 \\  \ \\ 4 \div 100 \times 1418

so that would be 70.9 house extra in the first year and 56.72 extra in the second year respectively.
so to find the total number of houses we must add 70.9 + 56.72 + 1418 which gives us 1545.62
at the last it is mentioned for us to round our answer to the nearest

they are asking us for the total number whole number
which is 1546
so there would be 1546 houses in the second year.

The lengths of two organisms, P and Q. were recorded. Organism Pis
Andrews [41]

Answer:

  P

Step-by-step explanation:

The SI prefixes nano- and pico- stand for ...

  nano- = 10^-9

  pico- = 10^-12

2500 picometers is 2500·10^-12 = 2.5·10^-9 = 2.5 nanometers.

25 nanometers is greater than 2.5 nanometers, so is the greater length. Organism P has the greater length.

The location of four game stops are on a coordinate grid are as follows: Stop 1 at (−2,1) Stop 2 at (−2, −7) ​​ Stop 3 at (5,−7)
Anuta_ua [19.1K]

Answer:

3750 ft

Step-by-step explanation:

Denote Stops as points A(-2,1), B(-2,-7), C(5,-7) and D(5,1) and find all distances between two consecutive points:

  • AB=\sqrt{(-2-(-2))^2+(1-(-7))^2}=8\ units;
  • BC=\sqrt{(-2-5)^2+(-7-(-7))^2}=7\ units;
  • CD=\sqrt{(5-5)^2+(1-(-7))^2}=8\ units;
  • DA=\sqrt{(5-(-2))^2+(1-1)^2}=7\ units.

The total distance Paolo walked is

8+7+8+7=30\ units.

Since 1 unit on the coordinate grid equals 125 feet, then the total distance Paolo walked is

30\cdot 125=3750\ ft.
