A human being blinks about 1,500 times in 2 1/2 hours.How many times will he blink in 10 hours?

Answer:

-1

Step-by-step explanation:

number explanation

1. 20 + 4x = 16

  -20           -20

2. 4x = -4

    4       4

3. -4 divided by 4 = -1

word explanation

1.rewrite the problem

2. subtract 20 from 20 and subtract 20 from 16

all of the numbers subtract 20 except the number with the variable

3. 20 - 20 = 0

16 - 20 = -4 because you take the sign of the bigger number

4. you bring down 4x divided by 4 it gets crossed out then you do -4 divided by 4 and your answer is

negative 1

-1

Answer:

X = S-R

Step-by-step explanation:

I don't really know what it means, maybe what makes sense is X = S-R?

Answer:

X = S-R

Step-by-step explanation:

We need to change the equation so that it shows X = .....

Thus, we move R to the opposite side of the equation, and we get...

X = S-R

(Since Positive R becomes negative after swapping sides)

The monthly payment for a one-year loan = $1,081.00

The higher the period of time, the lesser the monthly payment of a loan.

Claire needs to borrow $12,000 from a local bank with an interest of 8.1% which is,

8.1/100 × $12,000 =$972

This means after one year she will pay back;

$12,000 + $972 = $12,972

Therefore, monthly payment for a year loan = 12972/12

= $1,081.00

Answer:

1)An angle bisector is basically the division of an angle into two equal parts, so you should just draw a line in the middle after you found the angles using the compass

2) parallel lines is a pair of lines that never intersect, and are always the same distance apart. you should use the compass to draw a 90-degree angle at the end of the line XY, and use the straightedge to draw a line that is parallel to the line XY.

Answer:

see attached diagram

Step-by-step explanation:

Angle Bisector

The angle bisector bisects the angle into two equal angles.

Measure the angle EDF (I've measured this as 115°)

Divide this by 2:  115 ÷ 2 = 57.5°

Measure an angle of 57.5° from point D on the line DF and draw a line.

Parallel lines

Measure two lines of equal length from points X and Y at an angle of 90° to the line XY.  Join the points for the parallel line.

The angle bisector and parallel line are shown in red on the attached diagram.

Answer:

∠ ACD = 130°

Step-by-step explanation:

∠ ABC = 180° - 120° = 60° ( adjacent angles on a straight line )

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ ACD is an exterior angle of the triangle , then

∠ ACD = 70° + 60° = 130°

Answer:

Step-by-step explanation:

f"(x)=2

integrating

f'(x)=2x+c

f'(1)=2+c=4

c=4-2=2

f'(x)=2x+2

integrating

f(x)=2x^2/2+2x+a

f(x)=x^2+2x+a

f(2)=-2

(2)^2+2(2)+a=-2

4+4+a=-2

a=-2-8=-10

f(x)=x^2+2x-10

Answer:

(32)4 or 32×4=128. the ( ) is just a separation line that kinda means times

»f(x) = 7x² - 3x + 7

»f(2) = 7(2)² - 3(2) + 7

»f(2) = 7(4) - 6 + 7

»f(2) = 28 - 6 + 7

»f(2) = 29

»f(-1) = 7(-1)² - 3(-1) + 7

»f(-1) = 7(1) + 3 + 7

»f(-1) = 7 + 3 + 7

»f(-1) = 17

»f(0) = 7(0)² - 3(0) + 7

»f(0) = 7(0) - 0 + 7

»f(0) = 0 - 0 + 7

»f(0) = 7

so, f(2) + f(-1) + f(0) is

Answer:

3 ( 5a - 2b + 12)

Step-by-step explanation:

15 = 3 * 5

6 = 2 * 3

36 = 2 * 2 * 3 * 3

GCF = 3

15a - 6b + 36 = (3* 5 * a) - (3 *2 * b) + (3 * 12)

                    = 3 ( 5a - 2b + 12)

Step-by-step explanation:

Moving to the left of the number line means that the numbers are getting smaller, so with the example of

x < 3.5, x can be 3.4, 3.3, 3.2 and so on

Moving to the right of the number line means that the numbers are getting bigger, for example x > -1.5, x can be -1.4, -1.3, -1.2, -1.1, 0, 0.1, 0.2 and so on

x < 3.5 means that a number (x) is less than 3.5, so it's a hollow circle at 3.5 with the arrow to the left

x > -1.5 means that a number (x) is greater than -1.5, we cannot go the left of the number line as it will mean x is less than (<) -1.5, so it's a hollow circle at 1.5 with the arrow to the right

x ≥ -9/2 can be written as x ≥ -4.5 which means that a number (x) is greater than or equal to -4.5. It's a filled circle because you include -4.5 with the arrow to the right.

x ≤ 7/4 can be written as x ≤ 1.75 which means that a number (x) is less than or equal to 1.75, so it's a filled circle at 1.75 with the arrow to the left
