Answer:

118.2

Step-by-step explanation:

1.1m is 100%

2.4m×100=240

240/1.1= 218.(18)

218.(18)%-100%=118.(18)=118.2

Find the value of z.

nataly862011 [7]

Answer:

z = $\frac{50}{3}$

Step-by-step explanation:

The ratio of corresponding sides are equal, that is

$\frac{z}{10}$ = $\frac{20}{12}$ ( cross- multiply )

12z = 200 ( divide both sides by 12 )

z = $\frac{200}{12}$ = $\frac{50}{3}$

A lake has a large population of fish. On average, there are 2,400 fish in the lake, but this number can vary by as much as 155.

AleksAgata [21]

Answer:

Minimum population of fish in lake = 2400 - 155 = 2245

Maximum population of fish in lake = 2400 + 155 = 2555

Step-by-step explanation:

population of fish in lake = 2400

Variation of fish = 155

it means that while current population of fish is 2400, the number can increase or decrease by maximum upto 155.

For example

for increase

population of fish can 2400 + 2, 2400 + 70, 2400 + 130 etc

but it cannot be beyond 2400 + 155.

It cannot be 2400 + 156

similarly for decrease

population of fish can 2400 - 3, 2400 - 95, 2400 - 144 etc

but it cannot be less that 2400 - 155.

It cannot be 2400 - 156

Hence population can fish in lake can be between 2400 - 155 and 2400 + 155

minimum population of fish in lake = 2400 - 155 = 2245

maximum population of fish in lake = 2400 + 155 = 2555

Answer:

An equation of the line that passes through the point(2,−5) and is parallel to the line 6x+y=6 is:

$y=-6x+7$

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where m is the slope and b is the y-intercept

Given the equation

$6x+y=6$

Writing in the slope-intercept form of the line equation

$y = -6x + 6$

comparing with the slope-intercept form of the line equation

y = mx+b

Thus, the slope of line = m = -6

We know that the parallel lines have the same slopes.

Thus, the slope of the parallel line is also -6.

As the line passes through the point (2,−5).

Thus, using the point-slope form of the line equation

$y-y_1=m\left(x-x_1\right)$

where m is the slope and (x₁, x₂) is the point

substituting the values m = -6 and the point (2,−5)

$y-y_1=m\left(x-x_1\right)$

$y - (-5) = -6 (x - 2)$

$y+5=-6\left(x-2\right)$

subtract 5 from both sides

$y+5-5=-6\left(x-2\right)-5$

$y=-6x+7$

Therefore, an equation of the line that passes through the point(2,−5) and is parallel to the line 6x+y=6 is:

$y=-6x+7$

The directions for a homemade glass cleaner call for 1 part vinegar to 4 parts water. Mr. Gilbert mixed 2 cups of vinegar with 5

PolarNik [594]

No.
EXPLANATION:
To tackled this problem we should find an equivalent denominator.

We find that the lcm ( lowest common denominator ) is 20.

1 x 5 = 5
4 x 5 = 20

2 x 4 = 8
5 x 4 = 20.

so the answer is no.
