Three sisters are saving for a special trip . The ratio of Nora​'s savings to Helga​'s savings is 8:3 and the ratio of Helga​'s savings to ​Maurice's savings is 3:4. Together all 3 have saved ​$60. How much has each ​saved?

Answers

Answer:

X = 10.588

Y = 28.2

Z = 21.176

Step-by-step explanation:

Consider Nova savings as X

Helga is Y

Maurice is Z

As per first ratio we conclude 8X=3Y

Second ratio we conclude 3Y = 4Z

We deduce 8X = 4Z

Last sentence => X+Y+Z=60 multiple it by 3

=> 3X + 3Y + 3Z= 180 but 8X = 4Y

=> 3X + 8X + 3Z =180 => 11X + 3Z=180 multiple the equation by 4/3

44/3 X + 4Z = 240 but 4Z = 8X

=> 44/3 X + 8 X = 240

=> 68/3 X = 240

=> 68X = 720

=> X =10.588

And Y=8/3 X =28.2

And Z=3/4 Y = 21.176

the area of a certain desert is nine times the area of another desert. if the sum of their areas is 30,000,000 sq miles. find the area of each. ​

Answers

So the sum of both deserts is 30000000 and one is 9 times more than the other, it’s a 1:9 ratio. 9+1 is ten and 30000000/10 is 3,000,000. That’s the area of the smaller desert. You multiply 3 million by 9 and get 27,000,000 sq miles for the larger desert. Hope that makes some sense! :)

Step-by-step explanation:

g = 25 - 3r

Its telling you the r is 4 since its the input.

g = 25 - 3 ( 4 )   see!! just plug in the number

Now Solve

g = 25 - 12

g = 13

Answer:

g = 13

Step-by-step explanation:

since r = 4, you make the equation :

g=25-3(4)

first you multiply 3 and 4 and you get 12

g=25-12

and 25 - 12 is 13 which equals :

The measures of two complementary angles are described by the expression(13y+12) and (20y+12). Find the measures of angles​

Answers

Step-by-step explanation:

complementary angles means that both of them together = 90

13y +12 + 20y + 12 = 90

add all y together and numbers together

33y + 24 = 90

solve for y

33y= 66. y= 2

now let's get the measurements of the angles

Two forces with magnitudes 300 pounds and 450 pounds, with an angle of 60° between them, act upon an object. What is the approximate magnitude of the resultant force?

Answers

The resultant force in the example presented is approximately 774 pounds.

What is magnitude?

The magnitude or size of a mathematical item defines whether it is larger or smaller than other objects of the same kind in mathematics.

Formally speaking, the size of an object is the visible outcome of an ordering—of the class of objects to which it belongs.

Consider the following scenario: the force is 10 N in the east.

The direction is indicated by "towards the east," while the force is indicated by "10."

Magnitude can be thought of as simply the "value" or "amount" of any physical quantity.

So, an object is under the influence of two forces with respective magnitudes of 300 pounds and 450 pounds and an angle of 60 degrees between them.

F₁=300 pounds, F₂=450 pounds and θ=60°

Fr=√300²+450²+2×300×450×cos60°

= √90000+502500+13500×0.5

= √90000+502500+6750

= √599250

= 774 pounds

Therefore, the resultant force in the example presented is approximately 774 pounds.

solve this system using elimination. 3x - 4y = -5, -10x + 4 = 12

Answers

Answer:

x = -4/5, y = 13/20

Step-by-step explanation:

-10x + 4 = 12

-10x = 8

x = -4/5

3x - 4y = -5

3(-4/5) - 4y = -5

-12/5 - 4y = -5

-4y = -13/5

y = 13/20

Double check:

3x - 4y = -5

3(-4/5) - 4(13/20) = -5

-12/5 - 13 = -5 (true)
