Answer:

12 years

Step-by-step explanation:

Let x be the present age ( in years ) of Max and y be the present age ( in years ) of Zeke,

Max's age 3 years ago = x - 3

According to the question,

2 ( x - 3 ) + y = 26 -----(1)

Also, if Zeke's present age is 8 years,

That is y = 8,

From equation (1),

2x - 6 + 8 = 26

2x + 2 = 26

2x = 24

x = 12

Hence, Max is 12 years old currently.

The first step of solving this problem is to find your x, which is the unknown number. The unknown number is the age of Max. Once you find the x you can write out your equation.

The equation for this problem is:

2x+8=26

the first step is to subtract 8 from both sides so that all you have on the left side is 2x and your equation will look like ths:

2x=18

after subtracting the 8; divide everything by the coefficient of x which is 2, your result is:

x=9

Max is 9 years old.

Freida earns $5.25 per hour and time-and-a-half for overtime for all hours over 40 hours. How much did she earn the week she wor
nikdorinn [45]

Answer:

Total earned= $273

Step-by-step explanation:

Giving the following information:

Regular labor hours= $5.25

Overtime labor hours= $5.25*1.5= $7.875

<u>To calculate the total earned, we need to use the following formula:</u>

Regular labor hours= 40*5.25= 210

Overtime labor hours= 8*7.875= 63

Total earned= 210 + 63

Total earned= $273

A metal hollow bar whose cross section and dimension are shown below weighs 8x10^3 kg/m^3 and measure 2m in length ..determine t
devlian [24]
1) We calculate the volume of a metal bar (without the hole).

volume=area of hexagon x length
area of hexagon=(3√3 Side²)/2=(3√3(60 cm)²) / 2=9353.07 cm²
9353.07 cm²=9353.07 cm²(1 m² / 10000 cm²)=0.935 m²

Volume=(0.935 m²)(2 m)=1.871 m³

2) we calculate the volume of the parallelepiped

Volume of a parallelepiped= area of the section  x length
area of the section=side²=(40 cm)²=1600 cm²
1600 cm²=(1600 cm²)(1 m² / 10000 cm²=0.16 m²
Volume of a parallelepiped=(0.16 m²)(2 m)=0.32 m³

3) we calculate the volume of a metal hollow bar:
volume of a metal hollow bar=volume of a metal bar -  volume of a parallelepiped

Volume of a metal hollow bar=1.871 m³ - 0.32 m³=1.551 m³

4) we calculate the mass of the metal bar

density=mass/ volume  ⇒ mass=density *volume

Data:
density=8.10³ kg/m³
volume=1.551 m³

mass=(8x10³ Kg/m³ )12. * (1.551 m³)=12.408x10³ Kg

answer: The mas of the metal bar is 12.408x10³ kg  or   12408 kg

Answer:

XV = 4.75

Step-by-step explanation:

TV/WV = UV/XV (similarity theorem)

TW = 9

WV = 3

UV = 19

TV = 9 + 3 = 12

XV = ?

Plug in the values

12/3 = 19/XV

4 = 19/XV

XV × 4 = 19

XV = 19/4

XV = 4.75
