Jordan bikes at a speed of 8 2/3 mph. How many miles will he bike in:


45 minutes?

Answer:

  7:00 pm

Step-by-step explanation:

You want to know Alexandra's arrival time if she started at the same time as Michael (8:00 am) and drove at 45 mph, while Michael drove at 55 mph and arrived at 5:00 pm.

Travel time is inversely proportional to speed, so the time it takes Alexandra to make the trip is 55/45 = 11/9 times what it take for Michael to make the trip.

Michael's travel time from 8 am to 5 pm is 9 hours, so Alexandra's travel time is ...

  (11/9)(9 h) = 11 h

She will arrive 2 hours after Michael does.

Alexandra arrives at 7:00 pm.

Answer:

$48.72

Step-by-step explanation:

5.6 liters x $8.70 per liter= $48.72 total cost

Final answer:

To determine the total cost of the olive oil, multiply the quantity of 5.6 liters by the price per liter, which is $8.70. The total cost for the restaurant owner is $48.72.

Explanation:

The question asks us to calculate the total cost for a restaurant owner who buys 5.6 liters of olive oil at a price of $8.70 per liter. To find the total cost, we multiply the quantity of olive oil by the price per liter.

Calculation: Total cost = Quantity x Price per liter

Total cost = 5.6 liters x $8.70 per liter

Total cost = $48.72

Therefore, the restaurant owner will pay $48.72 for 5.6 liters of olive oil.

Answer: Its actually not. (maybe a typo)? The real bigger one is 5/8

Step-by-step explanation: So your question is "how much more is 1/8 than 5/8?" . The answer is its not. Lets do a example to help clarify. This is the butterfly method. this is by far the simplest way to compare fractions. Lets say your problem is " which is more, 5/8 or 3/4." the first thing you need to do is  line them up like so:

  5       3

  _       _

  8       4

The second thing to do is multiply the opposites.

  5       3

  _       _

  8       4

You would be multiplying 8*3 and 5*4 so like across or whatever.

put the answers on the equation like so,

20         24 <- Which ever in the top is bigger that would be 24. Which is 3/4

 5       3   ______________________________/

 _       _                                                                  

 8       4

3/4 is bigger in this problem.

First find m<HGC.

m<HGC=14 degrees (through vertical angles)

So...

m<HGE=14+78=92 degrees (through adjacent angles)

Now we have two parallel line cut by a transversal. And so... <HGE and <CEG are same side interior angles which means they are supplements (sum to 180 degrees)

m<HGE+m<CEG=180

92+m<CEG=180

m<CEG=88 degrees

<CEG and <CEB make a linear pair and are thus are supplements as well.

So...

m<CEG+m<CEB=180

88+m<CEB=180

m<CEB=92 degrees

m<CEB=4x=92

x=92/4=23 degrees

answer: 23 degrees

Answer:

3.728 cm²

90

Step-by-step explanation:

To built the envelope I am using a rectangular piece of material 28 m long and 12 m wide.  

Out of this material, I have to cut patches that are 1/12 the length and 2/15 the width of the whole material.

So, the length of the patches is [tex]28 \times \frac{1}{12} = 2.33[/tex] m and the width of the patches is [tex]12 \times \frac{2}{15} = 1.6[/tex] m.

Therefore, the area of the patches is (1.6 × 2.33) = 3.728 m² each. (Answer)

Now, the area of the rectangular piece of material is (28 × 12) = 336 m²

Hence, [tex]\frac{336}{3.728} = 90.37[/tex] ≈ 90 such patches can be made out of the whole material. (Answer)

To find how many times more water the bucket can hold than the jar, divide the bucket's capacity by the jar's capacity.

Explanation:

The bucket holds b liters of water, and the jar holds 8 fewer liters than the bucket. To find out how many times more water the bucket can hold than the jar, we need to compare their capacities. \

The bucket's capacity is b liters, and the jar's capacity is b - 8 liters.

To find the ratio of the bucket's capacity to the jar's capacity, we divide the bucket's capacity by the jar's capacity:

This ratio represents how many times more water the bucket can hold than the jar.

Answer:

Scale : 1 mm = [tex]\frac{1}{3}\ m[/tex]

Or

Scale : 3 mm = 1 m

Step-by-step explanation:

Let the scale used be 1 mm = 'x' m

Given:

Actual width of kitchen is 12 m.

Length used by Kate in drawing is 36 mm.

So, 36 mm in drawing is equivalent to 12 m in actual.

Therefore, 1 mm in drawing is equivalent to 'x' m in actual.

Taking proportions and solving by cross multiplication, we get

[tex]\frac{36}{12}=\frac{1}{x}\\36x=12\\x=\frac{12}{36}\\x=\frac{1}{3}\ m[/tex]

Therefore, 1 mm in drawing is equal to [tex]\frac{1}{3}\ m[/tex] in actual.

Scale : 1 mm = [tex]\frac{1}{3}\ m[/tex]

Or

Scale : 3 mm = 1 m

y - 3 = 4/6 * 3 = 2

y = 5

Answer:

Step-by-step explanation:

2x=(360÷4)

2x = 90

Dividing by 2

x = 90/2

x = 45

By following the steps of simplifying, isolating, and solving for x, we find that x = 45 is the value that satisfies the given equation.

To solve the equation 2x = (360 ÷ 4) for x, we need to isolate x on one side of the equation. Follow these steps to find the value of x:

Step 1: Simplify the expression on the right side of the equation.

360 ÷ 4 = 90

Step 2: Replace the right side of the equation with its simplified value.

2x = 90

Step 3: To isolate x, divide both sides of the equation by 2.

(2x) ÷ 2 = 90 ÷ 2

This simplifies to:

x = 45

The solution to the equation is x = 45. To verify, you can substitute x = 45 back into the original equation:

2(45) = 90

90 = 90

Since both sides of the equation are equal, x = 45 is indeed the correct solution.

Final answer:

To find how many text messages, x, Tim sent last month, use the equation: Total cost = fixed cost + variable cost. Given that Tim's phone bill was $30.58, the equation is $30.58 = $25.08 + $0.22x. Solving the equation gives x ≈ 25, so Tim sent approximately 25 text messages last month.

Explanation:

To find the number of text messages, x, Tim sent last month, we can use the equation:
Total cost = fixed cost + variable cost

Given that Tim's phone bill was $30.58, the fixed cost is $25.08. The variable cost is $0.22 per text message sent. Let's represent the number of text messages sent by x.

So, the equation becomes:
$30.58 = $25.08 + $0.22x

To solve for x, we need to isolate x. Subtract $25.08 from both sides of the equation:

$30.58 - $25.08 = $0.22x

Simplify:

$5.50 = $0.22x

Divide both sides of the equation by $0.22:

x = $5.50 / $0.22

x ≈ 25

Therefore, Tim sent approximately 25 text messages last month.

Solution:

[tex]f(x)+g(x)=(5x^{3} +3x^{2} -3)+(x^{2} +x-5)[/tex]

[tex]f(x)+g(x)=5x^{3} +3x^{2} -3+x^{2} +x-5[/tex]

[tex]f(x)+g(x)=5x^{3} +(3x^{2} +x^{2})+x-3-5[/tex]

[tex]f(x)+g(x)=5x^{3} +4x^{2}+x-8[/tex]

The equation of line T is 2x - y = 7 ⇒ (6x - 3y = 21)

Step-by-step explanation:

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size

Line L is mapped onto the line T by a dilation centered at the origin and  a scale factor of 3.

That means lint T is the image of line L after dilation

∵ The equation of line L is 2x - y = 7

∵ Line L is dilated by scale factor 3 and centered at origin

- That means multiply the equation of line L by 3 to find the

   equation of line t

∵ Line T is the image of line L after dilation

∴ The equation of line T is (3)(2x) - (3)(y) = (3)(7)

∴ The equation of line T is 6x - 3y = 21

Very important note:

The equation of line T is the same with equation of line L but multiplied by the scale factor 3 ⇒ L and T are coincide lines (same line)

That means the equation of lines T and L is 2x - y = 7

The equation of line T is 2x - y = 7 ⇒ (6x - 3y = 21)
