Answer:

The perimeter of the rectangle is 27n + 1 feet

Step-by-step explanation:

The formula of the perimeter of the rectangle is P = 2(L + W), where

  • L is the length of the rectangle
  • W is the width of the rectangle

∵ The width of a rectangle is 7n - 6.5 feet

∴ W = 7n - 6.5 feet

∵ The length of the rectangle is 6.5n + 7 feet

∴ L = 6.5n + 7 feet

→ Substitute W and L in the formula of the perimeter above

∵ P = 2[6.5n + 7 + 7n - 6.5]

→ Add the like terms

∴ P = 2[(6.5n + 7n) + (7 - 6.5)]

∴ P = 2[13.5n + 0.5]

→ Multiply the terms in the bracket by 2

∴ P = 27n + 1

∴ The perimeter of the rectangle is (27n + 1) feet

2/7m-1/7=3/14<br><br> Please solve showing work
lawyer [7]
(2/7)m - (1/7) = 3/14
2m/7 =(3/14) + (1/7)
2m/7 = (3/14) + 2(1/7)
here we are multiplying 2 with 1/7 to make the denominator same for addition.
2m/7 = (3/14) +(2/14)
2m/7 = (3 + 2)/14
2m/7 = 5/14
2m = (5 *7)/14
2m = 35/14
2m = 5/2
m = 5/4
m = 1.25
So the value of "m" is 1.25

12 – 7x ≤-2 <br> solve and show work
vova2212 [387]

Answer:

x≥2

Step-by-step explanation:

Let's solve your inequality step-by-step.

12−7x≤−2

Step 1: Simplify both sides of the inequality.

−7x+12≤−2

Step 2: Subtract 12 from both sides.

−7x+12−12≤−2−12

−7x≤−14

Step 3: Divide both sides by -7.

−7x/−7 ≤ −14/−7

x≥2

An Archer shoots an arrow horizontally at 250 feet per second. The bullseye on the target and the arrow are initially at the sam
Genrish500 [490]

Answer:

<h2>1.84feet</h2>

Step-by-step explanation:

Using the formula for finding range in projectile, Since range is the distance covered in the horizontal direction;

Range R = U\sqrt{\frac{H}{g} }

U is the velocity of the arrow

H is the maximum height reached = distance below the bullseye reached by the arrow.

R is the horizontal distance covered i.e the distance of the target from the archer.

g is the acceleration due to gravity.

Given R = 60ft, U = 250ft/s, g = 32ft/s H = ?

On substitution,

60 = 250\sqrt{\frac{H}{32}} \\\frac{60}{250} = \sqrt{\frac{H}{32}}\\\frac{6}{25} = \sqrt{\frac{H}{32}

Squaring both sides we have;

(\frac{6}{25} )^{2} = (\sqrt{\frac{H}{32} } )^{2} \\\frac{36}{625} =  \frac{H}{32} \\625H = 36*32\\H = \frac{36*32}{625} \\H = 1.84feet

The arrow will hit the target 1.84feet below the bullseye.

Solve -2x + 6 = -20.<br><br> (A) -13<br> (B) 13<br> (C) -7<br> (D) 7
kow [346]
Answer: x=13

explanation:
-2x+6=-20
subtract 6 from both sides
-2x=-26
divide -2 by both sides
two negatives equals a positive
x=13
