A rain barrel is full of water and used to water the garden. The rain barrel loses water at the rate 2.5 gallons of water per mi

soldier1979 [14.2K]

Answer: <span>y - 37.5 = 2.5 ( x - 7)

Explanation:

1) The point-slope form is has this form:

y - y1 = m (x - x1)

Where m is the slope or rate of change and x1, y1 are the coordinates of the point.

2) you are told that the the rate of change of water (m) is 2.5

m = 2.5

3) The point is given by that after 7 min the rain barrel contains 37.5 gallons. This is:

x1 = 7
y1 = 37.5

</span>4) Replace those value in the point-slope model:

y - 37.5 = 2.5 ( x - 7)

That is the point-slope model or equation.

The chef at a steakhouse has 350 pounds of sirloin steak on hand for Saturday night. If each portion is 10 ounces, how many sirl

GenaCL600 [577]

Answer:

560 dinners

Step-by-step explanation:

First, find the amount of ounces by multiplying 350 pounds by 16 since every one pound is 16 ounces. 350×16=5600. That means there are 5600 ounces of meat. Therefore, to find the amount of steaks that can be served, divide 5600 divided by 10. 5600÷10=560.

Can some one please help me with these five questions

valina [46]

Answer:

1)PT = 21 units

2)Option D

3)Option A

4)∠EFG = 2(24) +15 = 63 degrees

∠GFH= 4(24) +21 = 117 degrees

5) circumference = 21.98 cm

Step-by-step explanation:

1) As the T is midpoint, PT is equal to TQ in magnitude.

Thus, $4x+1=6x-9$

$2x = 10$

x=5.

Thus, PT = 4(5) + 1 = 21

2) The planes XTS and VRS intersect in the line SW, and the intersection is perpendicular.

3)For a line to be defined, it must have 2 points, start and end.

The option A) is not defined properly, so incorrect

4)As the angles are linear pair, their sum is 180 degrees.

Thus, $2n+15+4n+21 = 180$

$6n = 144$

n = $\frac{144}{6} = 24$

∠EFG = 2(24) +15 = 63 degrees

∠GFH= 4(24) +21 = 117 degrees

5) diameter = 7 cm

radius = 3.5 cm

circumference = $2\pi R = 2\pi (3.5) = 2(3.14)(3.5) = 21.98 cm$
