find four consecutive even integers such that 2 times the sum of the first and second is 14 more than 3 times the fourth.
motikmotik
Let the first integer  be x, then:-

2 (x + x+ 2) = 3(x + 6) + 14

4x + 4 = 3x + 18 + 14
x = 18 + 14 - 4 = 28 

the four  integers are 28,30,32 and 34.

A photo of a beetle in a science book is increased to 735​% as large as the actual size. If the beetle is 16 ​millimeters, what
wariber [46]

Answer: 117.6 millimeters

Step-by-step explanation:

Given , The actual size of beetle = 16 millimeters

Since , the photo of a beetle in a science book is increased to 735​% as large as the actual size.

Scale factor to increase the size = 735% = 7.35 [To convert percentage to decimal or fraction we divide it by 100]

Then , the size of the beetle in the photo would be :

(Actual size of the beetle) x (Scale factor)

= (16 millimeters) x (7.35)

= (16 x 7.35) millimeters

= 117.6 millimeters

Hence, the size of the beetle in the​ photo = 117.6 millimeters

Propane is stored in a cylindrical tank with a diameter of 15 inches and a height of 48 inches. Which equation could be used to
Virty [35]

Step-by-step explanation:

remember. the radius is always half the diameter.

volume of a cylinder

pi × r² × height

pi×7.5²×48 = pi×56.25×48 = 8,482.300165... in³

volume of a sphere

4/3 × pi × r³

and that volume should be the same as the cylinder. so,

4/3 × pi × r³ = pi×56.25×48

4/3 × r³ = 56.25 × 48

1/3 × r³ = 56.25 × 12

r³ = 56.25 × 36 = 7.5² × 6² = (7.5×6)² = 45² = 2025

r =  \sqrt[3]{2025}

which would be 12.65148998... in.
