Your mother gave you $13.32 with which to buy a present. This covered 3/5 of the cost. How much did the present cost?

A. Find the answer.

B. Write a formula for the problem.

Answers

Answer:

a. $22.2

b= 13.32/x=3/5

Step-by-step explanation:

13.32/x=3/5

13.32×5=66.6

66.6/3=22.2

x(present cost)=$22.2

Answer:

22.20$

3/5 * cost = 13.32

Step-by-step explanation:

3/5 * cost (total price) = 13.32 (we know that 3/5 of the price is 13.32)

to solve

5/3 to cancel out 3/5 and isolate the cost

5/3 * 13.32 = 22.20

​A rocket ship travels at 2.0×104 miles per hour. If a satellite is 2.5×105 miles from​ Earth, how long will it take the rocket to make the trip from Earth to the​ satellite? (Hint: Divide the distance to the satellite by the​ speed.) Write your answer in scientific notation.

Answers

Answer: Time taken =1.25 x 10^1 hours 0r  4.5 x 10^4s

Step-by-step explanation:

Step 1

how long will it take the rocket to make the trip from Earth to the​ satellite = Time taken for the rocket to make the trip from Earth to the​ satellite

Speed = Distance / Time ,

Time = Distance / speed

Step 2-- solving

Time = Distance / speed

Time=2.5×10^5 miles/2.0×10^4 miles per hour

=12.5 hours  = 1.25 x 10^1 hours

or 1.25 x 10^1 hours  x 3600 = 45,000 seconds = 4.5 x 10^4s

Answers

Answer:

x= 14/9 = 1 5/9

Step-by-step explanation:

Use the distributive property to multiply 2 by 5x−3.

2(5x−3)−4=x+4

Subtract 4 from −6 to get −10.

10x−6−4=x+4

Subtract x from both sides

10x−10=x+4

Combine 10x and −x to get 9x.

10x−10−x=4

Add 10 to both sides.

9x−10=4

Divide both sides by 9.

x=  14/9

Please mark brainliest.

​  

 

1. distribute --> 10x-6-4=x+4
2. do -6-4 --> 10x-10=x+4
3. add 10 on both sides --> 10x=x+4+10
4. subtract x on both sides and simplify equation --> 9x=14
5. divide both sides by 9 --> x=14/9

Answer:

  3x -4y = 12

Step-by-step explanation:

There are a number of different forms of the equation of a line. A few are ...

  y = mx + b . . . . slope-intercept form

  y -k = m(x -h) . . . . point-slope form

  x/a +y/b = 1 . . . . intercept form

  ax +by +c = 0 . . . . general form

  ax +by = c . . . . standard form

In "standard form", the coefficients a, b, c are mutually prime integers (have no common factors) and the leading coefficient (usually, 'a') is positive.

__

Given this graph, there are several ways to get to a standard form equation. Perhaps the quickest is to start with intercept form. We can see from the graph that the x-intercept is 4 and the y-intercept is -3. So, we can write the equation of the line in intercept form as ...

  x/4 +y/(-3) = 1

Multiplying this by 12 clears the fractions and gives us standard form:

  3x -4y = 12

Answers

Answer:

The distance between Supermarket A and Supermarket B is 35 units.

What is distance formula?

The distance formula which is used to find the distance between two points in a two-dimensional plane is also known as the Euclidean distance formula. On 2D plane the distance between two points (x₁, y₁) and (x₂, y₂) is Distance = √[(x₂-x₁)²+(y₂-y₁)²].

From the given coordinate plane, Supermarket A is at (12, 9), House is at (0, 0) and Supermarket B at (-16, -12).

1) Distance between Supermarket A and your house is

Substitute (x₁, y₁)=(12, 9) and (x₂, y₂)=(0, 0) in distance formula, we get

Distance = √[(0-12)²+(0-9)²]

= √144+81

= √225=15 units

2) Distance between Supermarket B and your house is

Substitute (x₁, y₁)=(-16, -12) and (x₂, y₂)=(0, 0) in distance formula, we get

Distance = √[(0+16)²+(0+12)²]

= √256+144

= √400=20 units

3) Distance between Supermarket A and Supermarket B is

Substitute (x₁, y₁)=(-16, -12) and (x₂, y₂)=(12, 9) in distance formula, we get

Distance = √[(12+16)²+(9+12)²]

= √28²+21²

= √1225=35 units

Therefore, the distance between Supermarket A and Supermarket B is 35 units.

3.3 in 2014. During this time period, the land area of Iceland was 100,250 square kilometers. By how many
people did Iceland's population increase from 1990 to 2014?
A 330,825
B 132,330
C 125,312
D 80,200

Answers

Given:

The population density of Iceland, in people per square kilometer of land area, increased from 2.5 in 1990 to  3.3 in 2014.

Land area of Iceland = 100,250 square kilometers.

To find:

The Iceland's population increase from 1990 to 2014.

Solution:

Land area of Iceland is constant, i.e., 100,250 square kilometers.

The population density of Iceland, in people per square kilometer of land area in 1990 is 2.5.  So, the population in 1990 is

[tex]2.5\times 100,250=250,625[/tex]

population density of Iceland, in people per square kilometer of land area in 2014 is 3.3.  So, the population in 2014 is

[tex]3.3\times 100,250=330,825[/tex]

The Iceland's population increase from 1990 to 2014 is

[tex]330,825-250,625=80,200[/tex]

Therefore, the correct option is D.

A producer received rupees 10000 when the price of a commodity was rupees 100 per unit. The receipts increased to rupees 15000 when price increased by rupees 20.Calculate the elasticity of supply?

Answers

Answer:

Price Elasticity of Supply = 1.25

Step-by-step explanation:

Price      Quantity        Total Revenue ( P x Q)

100     10000/100 = 100       10000

120      15000/120 = 125        15000

Price Elasticity of supply is change in quantity supplied, due to change in price. Formula : (dQ / dP) x (P / Q)

(125 - 100) / (120 - 100)   x (100/100)

= 25/20 = 1.25

An emperor penguin travels a distance of 70 miles each year back to the place of its birth. If that same penguin moves at a speed of 2.4 miles per hour, the function d = 70 – 2.4t represents its distance d from its birthplace t hours after it has started its journey home. Find the zero of this function.

Answers

Answer:

29.17 hours

Step-by-step explanation:

to find the zero of the function, set d to equal zero, so

0 = 70 - 2.4t

-70 = -2.4t

-70/-2.4 = t

29.17 = t
