Answer:

Slope = 24.000/2.000 = 12.000

When y = 0 the value of x is 5/-12 the line therefore crosses the x axis at x=-0.41667

x-intercept = 5/-12  = -0.41667

7. This year, the water in a reservoir dropped by 60%. For the original water level to be restored next year, by what percent mu
ale4655 [162]

Answer:

Given: Water in a reservoir dropped by 60%

Step-by-step explanation:

let the total water level of reservoir be 100.

then, in first year

the water reservoir dropped = 60% of 100

                                               =\frac{60}{100} * 100

                                               = 60

therefore, total water level needed to be restored till next year= 100

remaining water level to restore till next year= 100-60

                                                                           =40

                                                       percentage= \frac{40}{100} * 100

                                                                         =40%

3.1÷10.261 how to show my work
marissa [1.9K]
First, convert the decimals into improper fractions. The fractions are:
31/10 and 10261/1000. To divide the fractions, change division into multiplication after flipping the numerator and the denominator of the second fraction. This comes out to be 31/10 *(times) 1000/10261.
31*1000 is 31,000 and 10*10261 is 102,610. This equals the fraction: 31,000/102,610. Simplify this.
