How do the 5s in 50.8 and 18.35 compare?
telo118 [61]

The value of the 5 in 50.8 is 1,000 times the value of the 5 in 18.35 ⇒ 1st answer

Step-by-step explanation:

Let us revise some important notes in a number:

  • Every digit in a number has a place value
  • Place value is the value represented by a digit in a number
  • Ex: the place value of 2 in the number 2,345 is 1,000 because 2 is in the thousands place, the place value of 9 in 12.29 is 0.01 because 9 is in the hundredths place

∵ The number is 50.8

∵ 5 is in the tens place

∴ The place value of 5 is 10

∵ The number is 18.35

∵ 5 is in the hundredths place

∴ The place value of 5 is 0.01

Let us compare between the places value of 5 in the two numbers

Let x the number which multiplying by the hundredth digit to give the ten digit

∵ 10 = x × 0.01

∴ 10 = 0.01 x

- Divide both sides by 0.01

∴ 1,000 = x

∵ 5 × 10 = 0.05 × 1000

∴ 50 = 50

∴ The value of 5 in 50.8 = 1,000 × the value of 5 in 18.35

The value of the 5 in 50.8 is 1,000 times the value of the 5 in 18.35

Solve one of the two problems for x. The answers for both are the same. You are more than welcome to do both to check your answe
Fed [463]

Answer:

x = 49

Step-by-step explanation:

Let's solve for x in the first triangle by applying the leg rule.

Leg rule is given as: hypotenuse/leg = leg/part

Hypotenuse = x

Leg = 28

Part = 16

Plug in the values into the equation

x/28 = 28/16

Cross multiply

x*16 = 28*28

16x = 784

x = 784/16

x = 49

✔️Let's check our answer to see if we would get the same value of x for the other triangle. Apply the same leg rule.

Hypotenuse = x

Leg = 21

Part = 9

Thus:

x/21 = 21/9

Cross multiply

x*9 = 21*21

9x = 441

x = 441/9

x = 49

✔️We have the same value. Therefore, x = 49 is the correct answer.

BaLLatris [955]

Answer:

250 square feet

Step-by-step explanation:

This problem can be easily solved using ratios.

It says that  1\frac{1}{2} pound covers 375 sq. ft.

So, how much would 1 pound cover?

Let 1 pound cover "x" pounds. We can setup up two ratios and equate them. Then cross multiply and solve for x.

Note:  Pounds on numerator and Square Feet on denominator

\frac{1\frac{1}{2}}{375}=\frac{1}{x}\\1\frac{1}{2}*x=375*1\\1\frac{1}{2}x=375\\\frac{3}{2}x=375\\x=\frac{375}{\frac{3}{2}}\\x=375*\frac{2}{3}\\x=250

Hence, 1 pound of wildflower seeds will cover an area of 250 square feet
