Answer:

Step-by-step explanation:

To solve this you have to figure out how many pints are needed to get a gallon so you have pints which there should be 4 pints but you need more than 4 pints to make a gallon so multiply that by 2 then divide how much a gallon is to get the number of pints they drank in a week

Answer:

it would be the second one

Step-by-step explanation:

the only way that you could have a gallon is 8 pints, so if you divide the gallon by 8, you get a pint! hope this helps! have a nice day :)

Akimi4 [234]

Answer:

Step-by-step explanation:

4x - 12 ≤ 16 + 8x

4x - 8x ≤ 16 + 12

- 4x ≤ 28

x ≥ - 7 or [ - 7, ∞ )

Write an equation of the line that passes through (−1,3) and is parallel to the line y=2x+2.

MA_775_DIABLO [31]

The equation of the line that passes through (−1,3) and is parallel to the line y = 2x + 2 in slope intercept form is y = 2x + 5

<h3>Solution:</h3>

Given that line passes through (-1, 3) and parallel to line y = 2x + 2

We have to find the equation of the line

Let us first find the slope of the line

The slope intercept form of line is given as:

y = mx + c ---- eqn 1

where "m" is the slope of the line and "c" is the y-intercept

Comparing the given line equation y = 2x + 2 with y = mx + c,

We get slope "m" = 2

The slope of parallel lines are equal

Hence slope of the line which is parallel to y = 2x + 2 is also 2

Now let us find the equation of line with slope "m" = 2 and passes through point (-1, 3)

Substitute (x, y) = (-1, 3) in eqn 1 to find value of "c"

3 = 2(-1) + c

3 = -2 + c

c = 5

Now substitute "c" = 5 and m = 2 in eqn 1 to get equation of required line

y = 2x + 5

Thus the equation of line in slope intercept form is y = 2x + 5

(image) The figure below is an isosceles triangle surmounted by a semi-circle. Find the area of the entire region.

S_A_V [24]

Answer:

12.53

Step-by-step explanation:

∠BCA = (180°-40°)/2 = 70°

Laws of Sines: CA/sin 40° = AB/sin 70° = 5/sin 70°

CA = 5/sin 70° * sin 40° = 3.40

area of semicircle CA = (3.1416 * 1.70²) / 2 = 4.54

By Heron's Formula, area of triangle ABC:

1/4 √(a+b+c) (a+b-c) (b+c-a) (c+a-b) = 1/4 * √13.4*3.4*3.4*6.6

= 7.99

Entire region area = 4.54 + 7.99 = 12.53
