Harold walks 3/4 mile in each 5/6 hour. Calculate Harold's unit rate. Explain how you found your answer.

Answers

Answer 1
Answer: To solve this problem, you must apply the proccedure shown below:

 1. The problem gives the following information: Harold walks 3/4 miles in each 5/6 hours. Therefore, you have to divide  3/4 miles by 5/6 hours, as below:

 unit rate=(3/4)(5/6)
 unit rate=(3x6)(4x5)
 unit rate=18/20 

 3. When you simplify, you obtain:

 unit rate=9/10

 4. Therefore, as you can see, the answer is: Harold's unit rate is 9/10.

Marissa researched the cost to have custom T-shirts printed by several local and online vendors. She found that each store’s charge for the job could be modeled by a linear function that combined a flat charge for artwork with a per T-shirt rate. Marissa plotted the functions on a coordinate grid and found that two of the functions produced lines that had the same y-intercept. How should Marissa interpret this result?A.Those two vendors charge the same rate per shirt.B.Those two vendors charge the same flat rate for artwork.C.Those two vendors will have the same total cost to produce one shirt.D.Those two vendors will charge the same total cost for any size job.

2x+4y=12 -2x+3y=26 elimination

Answers

2x + 4y = 12
-2x + 3y = 26

Add the two equations, and you get:

2x + (-2x) + 4y + 3y = 12 + 26

4y + 3y = 12 + 26

7y = 38

y = 38/7

Plug y = 38/7 and solve for x.

2x + 4(38/7) = 12

2x + 152/7 = 12

2x = 12 - 152/7

2x = 84/7 - 152/7

2x = (84 - 152)/7

2x = -68/7

x = -68/7 * 1/2

x = -34/7

x = -34/7
y =  38/7

x = -4 6/7
y = 5 3/7

The solution is (-4 6/7, 5 3/7) OR (-34/7, 38/7).

Both the answers are correct. It's just that in one answer, the fraction is in mixed form, and the other answer has it as an improper fraction.

ΔABC ~ ΔBDC ~ ΔADB

Step-by-step explanation:

ΔABC, ΔBDC, and ΔADB are all similar triangles to each other.

By definition of similar triangles, the corresponding sides have the same ratios.

CD from ΔBDC corresponds to BD from ΔADB, and BD from ΔBDC corresponds to AD from ΔADB. So:

CD / BD = BD / AD

10 / x = x / 5

x² = 50

x = 5√2

Since ΔBDC is right, we can use the Pythagorean Theorem to solve for y:

CD² + BD² = BC²

10² + (5√2)² = y²

y² = 100 + 50 = 150

y = 5√6

Again, since ΔΔABD is right, we can use the Pythagorean Theorem to solve for z:

AD² + BD² = AB²

5² + (5√2)² = z²

z² = 25 + 50 = 75

z = 5√3

Answer:

x² = 5×10

x = √50

x = √5²×2

x = 5√2

z² = 5² + (5√2)²

z = √25 + 50

z = √75

z = √5²×3

z = 5√3

y² = 10² + (5√2)²

y = √100 + 50

y = √150

y = √5²×6

y = 5√6

x = 5√2

y = 5√6

z = 5√3

ΔABC ≈ ΔBDC ≈ ΔADB

How do i round 3,176 to the nearest thousand

Answers

Here is the rule: 4 and below let it go (round down), 5 and above give it a shove (round up)
Look to the place after the thousandths in the number 3,176 (the 1)
Since it is below 5, you would round down to 3,000
Well you would look at the 176 in 3,176. Since it is less then half (500) you would round it down. So 3,176 rounded to the nearest thousand would be 3,000

What is the shape of the following cross section????

Answers

The shape of the triangle is the cross-section part of the given figure. Thus, option A is correct.

How to find the shape inscribed in a square?

The cross-section part of the given figure could be the shape fro the inscribed figure.

Here we can see that the three-dimensional figure inscribed in the square is a cone.

The right circular cone is the cone in which the line joining peak of the cone to the center of the base of the circle is perpendicular to the surface of its base.

But for the plane of the square, the triangle is the cross-section part of the given figure.
