Answer:

2 hours: 27 miles, 3 hours: 40.5 miles, 3.5 hours: 47.25 miles

Step-by-step explanation:

1.) If a hiker hikes 9 miles in 2/3 of an hour, he will hike 4.5 (Half of 2/3 is 1/3 and half of 9 is 4.5) miles in 1/3 of an hour and 13.5 miles per hour. (1/3 times 3 gives us a whole and 4.5 times 3 is 13.5)

2.) 2 hours: 13.5 * 2 = 27 miles

3.) 3 hours: 13.5 * 3 = 40.5 miles

4.) 3.5 hours: 13.5 * 3.5 = 47.25 miles

9 miles in 2/3 of a hour.

in 1 hour = 9 X 3/2 = 18.2 miles

In 2 hrs = 27 miles

in 3 hrs = 54.6 miles

in 3.5 hrs = 63.7 miles

Answer:

C.

Step-by-step explanation:

the answer is 403

Answer:

C

Step-by-step explanation:

It wouldn't be A since 5 - 1 you would get 4 hundred not 4 tens. It wouldnt be B because 9 - 6 you would get 3 ones not 3 hundreds and 5-1 you would get 4 hundreds not 4 ones. It wouldnt be D because 9-6 would be 3 ones not 3 tens. Hope I helped ! Good luck !

Answer: y=-9/8x+7

Step-by-step explanation:

Answer:

[tex]y = \frac{ - 9}{8} x + 7[/tex]

Step-by-step explanation:

Slope intercept form is

y=mx+b

(m) is slope

(b) is y intercept

The y intercept is where ethe line crosses the y axis [vertical axis]

The line crosses at (0, 7)so our b=7, now we need slope.

The formula for slope is (y₂-y₁)/(x₂-x₁),

which is the y of the second given point minus the y of the first given point divided by the x of the second given point over the x of the 1st given point.

(-2-7)/(8-0)

-9/8 is our slope

put our (m) and (b) into the formula

y=-9/8x+7

Hope this helps! If you have any questions on how I got my answer feel free to ask. Stay safe!

n=17                                f=40

Answer:

La escala es 1 : 10000 centimetros

Eso significa que por cada centimetro que una persona mide en el mapa, en la vida real la distancia es 100 metros.

Por ejemplo, si usamos una regla para medir la distancia en el mapa y medimos que entre la escuela y el mercado hay una distancia de 7 centimetros (siguiendo las calles, no en linea recta), entonces la distancia a caminar para ir de la escuela al mercado es de 700 metros. Debemos ser cuidadosos y medir la distancia siguiendo las calles, ya que si medimos en linea recta la distancia puede ser menor, pero los humanos no volamos.

Answer:

r = 0

Step-by-step explanation:

-32r + 8 = -8r + 8

-32r + 8r = 8-8

-24r = 0

divide both sides by -24

then the answer will be -- r = 0

Domain: [1, 6]

Range: [1, 7]

General Formulas and Concepts:

Alg I

Step-by-step explanation:

We can find our domain and range from looking from the graph.

Domain

Domain encompasses x-values. According to the graph, the x-values span from 1 to 6. Since both are closed dots, they are included in the domain:

[1, 6] or 1 ≤ x ≤ 6

Range

Range encompasses y-values. According to the graph, the y-values span from 1 to 7. Since both are closed dots, they are included in the range:

[1, 7] or 1 ≤ x ≤ 7

Easy way to remember this: for Domain, look only at the x-axis and for Range, look only for the y-axis.

Step-by-step explanation:

-5400/-450

12 minutes

Answer:

12 minutes

Step-by-step explanation:

If the rate of the plane is -450 meters per minute, then you have to use the "division" operation in order to know how much time it takes for the plane to reach an altitude of -5,400 meters.

-5,400 meters ÷ -450 meters/minute = 12 minutes

It will take 12 minutes for the plane to reach an altitude of -5,400 meters.

Let's check:

-450 meters x 12 minutes = -5,400 meters

Answer:

1 pound of avocado costs $1.8

Step-by-step explanation:

Allow me to rewrite your question for a better understanding and hope it ill fit the original one:

The double number line shows that 5 pounds of avocados cost $9. Based on the ratio shown in the double number line, what is the cost for 1 pound of avocados?

Here is my answer:

Given that:

5 pounds avocados = $9

They want to find out:

cost of 1 pound of avocado

So we use division to solve this problem:

$9:5 pounds = $1.8/pound or:

1 pound of avocado costs $1.8

Hope it will find you well

Thank you.

Answer:

4

Step-by-step explanation:

25/100 x 80/1 = 20/1

80 - 20 = 60

30/100 x 80/1 = 24/1

80 - 24 = 56

60-56=4

Answer:

The number of places correctly identified is 110 places

Step-by-step explanation:

The number of places he correctly identified will be;

11 + 4 + 86 + 9 = 110 places

By using compatible numbers, we refer to the fact that she use an estimate by making sure each of the numbers are closer to the nearest 10th or 5

so 4 will be 5

11 will be 10

86 will be 85

9 will be 10

Adding all of these together, we have

5 + 10 + 85 + 10 = 110

Answer:

-3/3

Step-by-step explanation:

Answer:

100

Step-by-step explanation:

Answer:

1.three sides polygon have

2. i think 11- gons has regular properties so the equation for this would be 1620 divided by 11 and it equals 147.27 so the meauser of the interirinangle of a 11-gon is about 147.27 degrees.

3.8 sides

Step-by-step explanation: if the sum of the angles is 10,800 degrees and each angle is 1,350 degrees, the deck will have the number of sides of the sum of the angle measurements divided by each angls measurmeasur.ments

10,800/1,350=1,080/135= 8 sides

Pease mark me brainlist.

The main idea is using the Pythagorean formula to find the length of line segment [tex]DB[/tex].

Alr so you use the formula [tex]A^2 + B^2 = C^2[/tex]

[tex]C^2[/tex] is already given and is [tex]2\sqrt{5}[/tex]

and [tex]A^2[/tex] is [tex]3\sqrt{2}[/tex]

So using algebraic rules you'll get [tex]B[/tex] as:

[tex]\sqrt{2}[/tex]

Now using the formula: [tex]\frac{1}{2} b * h[/tex], you can find the area of tri ABD and CBD which would be [tex]3[/tex] and [tex]1[/tex] so add them up and you get [tex]4[/tex]!

Answer:

8 full practice

Step-by-step explanation:

Given that :

Morning Practice hours Total = 12 hours

Afternoon practice hours total = 14 hours

practice length = 3 hours

Hence, Number of full practices attended :

practice hours / practice length

Morning : 12 / 3 = 4 practice sessions

Afternoon = 14 / 3 = 4.666 sessions

Hence, number of full practice completed = 4 + 4 = 8
