Joe walked 4/9 of a mile in 4/5 of an hour. What is his unit rate in miles per hour? 4/9 over 4/5 = 5/9 mile per hour 4/5 over 4/9 = 1 and 4/5 miles per hour 4/9 over 4/5 = 1 and 4/5 miles per hour 4/5 over 4/9 = 5/9 mile per hour

Answers

Joe walks at approximately .56 mph.

4/9= .444...
4/5= .8

.444 miles /.8 hours= x miles /1 hour
x= .56 mph

If Joe walked 4/9 of a mile in 4/5 of an hour then the unit rate is  5/9 miles/hour.

What is Division?

A division is a process of splitting a specific amount into equal parts.

The distance walked by Joe is 4/9 of a mile.

The time taken by Joe to walk 4/9 of a mile is 4/5 of an hour.

We need to find the unit rate in miles per hour.

To find this we just need to divide 4/9 by 4/5.

Rate = Distance/Time

Distance = 4/9 miles

Time = 4/5 hour

Rate  = 4/9 ÷ 4/5

Rate = 4/9 × 5/4

Rate = 5/9 miles/hour.

Hence, if Joe walked 4/9 of a mile in 4/5 of an hour then the unit rate is  5/9 miles/hour.

a desert has both fruit and yogurt inside altogether the mass of the desert is 185g the ratio of the mass to fruit to the mass of yoghurt is 2:3 what is the mass of yoghurt?

Answers

fruit : yoghurt : total
2 : 3 : 2 + 3
2 : 3 : 5

5 parts = 185
1 part = 185 ÷ 5 = 37
3 parts = 37 x 3 = 111g

The mass of the yoghurt is 111g

The mass of the fruit is 74 grams and the mass of the yoghurt is 111 grams.

Given :

Total mass of the desert is 185 g.The ratio of the mass to fruit to the mass of yoghurt is 2:3.

Solution :

This question is solved by making a linear equation in one variable. Linear equations are nothing but yet another subset of "equations". Any linear calculations requiring more than one variable can be done with the help of linear equations. The standard form of a linear equation in one variable is of the form ax + b = 0. Here, x is a variable, and a and b are constants.

Now to form a linear equation first let x be the mass in gram. Than total mass of the desert is given by:

[tex]3x+2x=185[/tex]

[tex]5x = 185[/tex]

[tex]x = \dfrac{185}{5}[/tex]

x = 37 grams

Therefore the mass of the fruit = [tex]2 \times 37[/tex] = 74 grams and the mass of the yoghurt = [tex]3\times 37[/tex] = 111 grams.

Using V = lwh , find an expression in factored form for the volume of this prism. Explain the general steps you used to arrive at this answer.

Answers

You are asked to use the volume formula V = lwh which basically means to find the volume by multiplying the length, width and height of the prism. These are all given to you as expression so you are asked to multiply the expressions. That is, find: [tex]( \frac{ x^{2} -x}{4x+1} )( \frac{2x-5}{1} )( \frac{24 x^{2} +6x}{x-1} )[/tex]

First factor each of the expressions in the numerators and then multiply those in the numerators putting them over those in the denominator. It turns out those in the denominators (in this problem) cannot be factored. When you do this you are left with:
[tex]\frac{(x)(x-1)(2x-5)(6x)(4x+1)}{(4x+1)(x-1)} [/tex]

You can divide out (sometimes called cancelling out) those terms expressions that are in both the numerator and the denominator. That leaves you with:
[tex]\frac{(x)(2x-5)(6x)} {1}[/tex] which we can clean up by multiplying x and 6x in the numerator.

Thus, the volume of the prism is: [tex]6 x^{2} (2x-5)[/tex]
We do not multiply this out because it is now written as a product and thus factored (as you were asked).

The volume of the prism with the given dimensions is;

V = 12x³ - 30x²

We are given that the formula for the volume of a cube is;

V = Lwh

where;

L is length

w is width

h is height

We are given;

L = (24x² + 6x)/(x -1)

w = 2x - 5

h = (x² - x)/(4x + 1)

This means that;

V = [(24x² + 6x)/(x - 1)] × (2x - 5) × [(x² - x)/(4x + 1)]

Now, let us factorize the terms that can be factorized;

(24x² + 6x)/(x - 1) can be factorized into; [6x(4x + 1)/(x - 1)]

Similarly;[(x² - x)/(4x + 1)] can be factorized into [x(x - 1)/(4x - 1)]

Using the factorized terms to get the volume now;

V = [tex]\frac{6x(4x + 1)}{x -1} * (2x - 5) * \frac{x(x - 1)}{4x + 1}[/tex]

(x - 1) will cancel out and also 4x + 1 will cancel out to give;

V = 6x * x * (2x - 5)

V = 6x²(2x - 5)

V = 12x³ - 30x²

a women has a ladder that is 13 ft long. if she sets the base of the ladder on level ground 5ft from the side of a house, how many feet above the ground will the top of the ladder be when it rests against the houlad

Answers

It is convenient to remember that 5-12-13 is a Pythagorean triple.

Her ladder is 12 ft above the ground where it rests on the house.

_____
Using the Pythagorean theorem, you are given the hypotenuse as 13 ft and one leg as 5 ft. Then the other leg is
.. √(13^2 -5^2) = √(169 -25) = √144 = 12

Final answer:

Using the Pythagorean theorem, it is determined that the ladder reaches 12 feet up the side of the house when the base is placed 5 feet away.

Explanation:

To solve for the height at which the ladder reaches the house, we can use the Pythagorean theorem, which relates the lengths of the sides of a right triangle.

In this scenario, the ladder represents the hypotenuse (c), the distance from the base of the ladder to the house gives one leg of the triangle (a), and the height the ladder reaches up the side of the house is the other leg (b).

Let a = 5 ft (distance from the ladder's base to the house).Let c = 13 ft (length of the ladder).We need to find b (the height the ladder reaches the house).

According to the Pythagorean theorem, a² + b² = c². Plugging in our known values allows us to solve for b²:

a² = 5² = 25.c² = 13² = 169.Subtract a² from c² to get b²: 169 - 25 = 144.Take the square root of b² to find b: √144 = 12.

Therefore, the top of the ladder will be 12 feet above the ground.

To solve this equation, simply plug in the value of h = 0 feet, as this would be the height the object will be on the ground. It would be 0.

Chantelle is going on an 8 day hike of 82.5 miles. she plans to hike 8.25 hours everyday for each of those 8 days. how many miles will she covet each hour of her trip?

Answers

Final answer:

Chantelle will cover 1.25 miles each hour of her hike.

Explanation:

To find out how many miles Chantelle will cover each hour of her trip, we need to divide the total distance of 82.5 miles by the total time of 8.25 hours per day for 8 days.

First, we calculate the total time of the trip by multiplying the hours per day (8.25) by the number of days (8): 8.25 hours/day x 8 days = 66 hours.

Next, we divide the total distance by the total time: 82.5 miles / 66 hours = 1.25 miles/hour.

Therefore, Chantelle will cover 1.25 miles each hour of her hike.

If 2(x + 3) = x + 10, then x equals what

Answers

Final answer:

To solve the equation, we first distribute the 2 on the left, then collect like terms and finally isolate x. The solution to the equation 2(x + 3) = x + 10 is x = 4.

Explanation:Solution for the Equation

To solve the equation 2(x + 3) = x + 10, we will first distribute the 2 on the left-hand side of the equation to get 2x + 6. Therefore, the equation becomes: 2x + 6 = x + 10.

The next step is to collect like terms. To do this, we subtract x from both sides, which gives us: x + 6 = 10.

Finally, to solve for x, we subtract 6 from both sides of the equation: x = 4. Hence, the solution to the equation 2(x + 3) = x + 10 is x = 4.

Final answer:

x = 4

Explanation:

To solve the equation 2(x + 3) = x + 10, we first expand the left side of the equation:

2 × x + 2 × 3 = x + 10

2x + 6 = x + 10

Now subtract x from both sides to move all x terms to one side:

2x - x + 6 = 10

1x + 6 = 10

Subtract 6 from both sides to solve for x:

x = 10 - 6

x = 4

Thus, the solution to the equation is x = 4. Checking the solution, we substitute x back into the original equation:

2(4 + 3) = 4 + 10

Milo's pancake recipe makes 9 servings. It calls for 3/4 cup milk. Milo wants to make 6 servings. How much milk will he need?

Answers

1/2 cup of milk for 6 servings

It says that the recipe for 9 servings would require 3/4 cup milk.

He wants to prepare recipe for 6 servings. Let's assume it requires X cups milk.

Now we can use concept of proportions to solve this problem.

The proportion of X cups for 6 servings would be same as 3/4 cup milk for 9 servings. Mathematically, we can write it as follows :-

[tex] \frac{X \;cups \;milk}{6 \;servings} = \frac{\frac{3}{4} \;cups \;milk}{9 \;servings} \\\\
Or\; \frac{X \;cups \;milk}{\frac{3}{4} \;cups \;milk} = \frac{6 \;servings}{9 \;servings} \\\\
\frac{X }{\frac{3}{4} } = \frac{6 }{9 } \\\\
X = \frac{6}{9}*\frac{3}{4} \\\\
X = \frac{6*3}{9*4} \\\\
X = \frac{18}{36} \\\\
X = \frac{1}{2} \;cup \;milk [/tex]

Hence, we require [tex] \frac{1}{2} [/tex] cup milk for 6 servings.
