The weight of an object on Mars varies directly with its weight on Earth. An object that weighs 50 pounds on Mars weighs 150 pounds on Earth. Determine a direct variation equation to represent this situation. If an object weighs 120 pounds on Earth, determine how much an object would weigh on Mars. Enter this amount, in pounds, into the space provided (enter numerical number only, not the units).

Answers

Answer 1

The weight of the object on Mars would be 40 pounds.

What are ratio and proportion?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

An object that weighs 50 pounds on mars weighs 150 pounds on earth.

Let the object weighing 120 pounds on Earth, weighs x pounds on Mars.

We can solve this equation as :

                50/150 = x/120

                 x = 40 pounds

Hence, the weight of the object on Mars would be 40 pounds.

0.14 cm = ______ m




Conversions

Answers

Answer:

0.14 cm = 0.0014m

Step-by-step explanation:

So the phrase is:

“King Henry Died Belly Up Drinking Chocolate Milk”

The c is centimeters and meters is in between "died" and "drinking".

So 0.14 cm = 0.0014m

Because you are moving 2 to the left on the phrase so you move the decimal point 2 to the left.

***Belly up is bolded because it stands for base unit (meters, liters, gram, etc.)

Answers

Answer:

It is 2.

Step-by-step explanation:

The equation becomes -2y=-4x=5

But you divide by -2 to get y solo. So -4/-2=2.

Answer:

slope = 2

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

4x - 2y = 5 ( subtract 4x from both sides )

- 2y = - 4x + 5 ( divide all terms by - 2 )

y = 2x + [tex]\frac{5}{2}[/tex] ← in slope- intercept form

with slope m = 2

What is X?
Thanks so much xx

Answers

Answer:

X= 7

Step-by-step explanation:

Well first combine like terms

27x-9=180

Isolate from the variable

27x=189

x=7

The final answer is 7

Answer:

x =7

Step-by-step explanation:

( 10x -1) +(17x -8 ) =180

step 1 : since you have a plus sign in between it make it easy

so take care of the parentheses first

10x -1 + 17x - 8 = 180

step 2 : put together thw variable x

10x + 17x -1 -8 = 180

27x -9 =180

step 3 : take out -9 to the right and the sign will change

27x = 180 +9

27x = 189

x = 189 ÷ 27

x = 7

You are testing two food scales for accuracy by weighing two different types of foods. Use the drop-down menus to complete the statements about the scales' accuracy. Scale 1 Measured Weight Actual Weight 85 oz 100 oz Scale 2 Measured Weight Actual Weight 47 oz 50 oz CLEAR CHECK Because the object on Scale 1 weighs more than the object on Scale 2, each ounce of error results in a lesser percent error. Scale 1 was 15 ounces off and Scale 2 was 3 ounces off, so Scale 1 was % off and Scale 2 was % off.

Answers

Answer:

scale 1 was 15% off and SCALE 2 was 6% off

Step-by-step explanation:

Scale __ Measured Weight ____Actual Weight

1_________85 oz _______________100 oz

2 ________ 47 oz _______________ 50 oz

Percentage error :

[(|measured - actual |) ÷ actual] * 100%

Scale 1 :

|85 - 100| = 15 oz

15 / 100 * 100% = 15%

Scale 2 :

|47 - 50| = 3 oz

3 / 50 * 100% = 0.06 * 100% = 6%

Hence, scale 1 was 15% off while SCALE 2 was 6%

The volume of the rectangular prism is ________ cm3

Answers

Answer:

volume of rectangular prism =l×w×h

volume of rectangular prism =4cm×2cm×7cm

volume of rectangular prism =56cm³

Answer:

The volume of the rectangular prism is [tex]56cm^3[/tex]

Step-by-step explanation:

To find the volume of a rectangular prism, you need to multiply the length, width, and height of the rectangular prism altogether. In this case, the length is 4cm, the width is 2cm, and the height is 7cm. So the volume of the rectangular prism would be [tex]7*2*4[/tex] = [tex]7 * 8[/tex] = [tex]56cm^3[/tex].

Answer: Annalise says that Philip will earn $320 more at First Bank than at GrandBank.

Step-by-step explanation:

Formula for Simple interest = Principal × Rate × Time

At GrandBank, the simple Interest will be:

= $2000 × 6% × 8

= $2000 × 0.06 × 8

= $960

At First Bank, the Simple interest will be:

= $2000 × 8% × 8

= $2000 × 0.08 × 8

= $1280

Based on the above, Philip will earn ($1280 - $960) = $320 more at First Bank.
