amm1812

Answer:

-2343 is a negative integer.

Step-by-step explanation:

There are different types of numbers:

a. Natural number or counting number

These number are greater than zero and begin with one and goes to infinity

(1, 2, 3, 4,.............., ∞)

b. Whole number

These number are almost like natural number, however, it also include zero in it´s number.

(0, 1, 2, 3,.........., ∞)

c. Integer number

These number include all positive, negative number and Zero except fraction component.

( -∞,.....,-2343,-2342,.........,-3,-2,-1,0,1,2,3,......,∞)

∴ -2343 is a negative integer.

14. Divide and write the fraction or mixed number in its simplest form:1/4÷3/8

sasho [114]

Answer:

1/4 ÷ 3/8 = 2/3

Step-by-step explanation:

When dividing fractions, you have to take the reciprocal of the second fraction, then multiply from there. The reciprocal of a fraction is basically flipped. So then, 1/4 ÷ 3/8 becomes 1/4 x 3/8. Multiplying fractions should be pretty straight forward as you just need to multiply numerator (top number of a fraction) with numerator and vice versa for the denominators (bottom number of a fraction).

So then you get: (1 x 8)/(3 x 4) = 8/12. Then you just simplify it by dividing the numerator and denominator by their greatest possible factor, which in this case is 4. So then, (8 ÷ 4)/(12 ÷ 4) = 2/3.

The time t required to do a job varies inversely as the number of people working. It takes 4 hr for 7 cooks to prepare the food

allochka39001 [22]

9514 1404 393

Answer:

3 1/2 hours

Step-by-step explanation:

If there are 8/7 times as many cooks, it will take 7/8 the amount of time. (That's what "inversely proportional" means.)

(7/8)(4 h) = 28/8 h = 3 1/2 h

It will take 8 cooks 3 1/2 hours to prepare the dinner.

Help!!!

Alinara [238K]

Answer:

5) B. (−2, 0), (−3, 0), (5, 0)

6) B. 15.87%

7) C. (5x − 4)(x + 2)

17) B. This is an example of causation but not correlation best describes the situation.

Step-by-step explanation:

5) See the first picture

7) ax²+bx+c → 5x²+6x-8

a · c = 5 · -8 = -40

? · ? = -40 → -4 ·10 =-40

5x² + 10x - 4x - 8

roup → (5x² + 10x) + (-4x - 8)

factor → (5x - 4)(x + 2)

17) Causation is the capability of one variable to produce an effect on another. This is also known as cause and effect. There is a causal relationship between the two variables. The effect of the fertilizer (variable) on the plant which brings about a noticeable difference in the color of the leaves of the plants is causation. Correlation only describes the extent to which two variables is likely to decrease or increase in parallel.
