HEEEELP i really really need help!

Answer: The grade of the hill = 50%

Step-by-step explanation:

The grade is the slope( expressed as a percent). To evaluate the slope we divide the rise by the run.

Given: A hill on a hiking trail goes up to 69 feet over a distance of 138 feet.

So, rise= 69 feet   , run = 138 feet.

The grade of the hill = [tex]\dfrac{rise}{run}\times100[/tex]

[tex]=\dfrac{69}{138}\times100=50\%[/tex]

Hence, the grade of the hill = 50%

Answer/Step-by-step explanation:

In the situation explained in the question, the cost of shipping is dependent on the weight of the box to be shipped.

For a box of 4 pounds, total shopping cost (x) => $15 (y)

For a box of 8 pounds (x), total shopping cost => $23 (y)

Therefore:

a. The input is weight of box

b. The output is cost of shipping

c. Using the 2 given pair (4, 15) and (8, 23), slope is calculate using the formula below:

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{23 - 15}{8 - 4} = \frac{8}{4} = 2 [/tex]

Slope = 2

d. The slope represents the amount charged per pound of weight. That is, $2 per pound.

e. Let's derive an equation to represent the situation using the slope-intercept formula given as y = mx + b

y = total cost of shipping

x = weight of box

m = average cost per pound = slope

b = y-intercept = flat fee charged for shipping before adding the cost of weight per pound

Substitute x = 4, y = 15, m = 2 into y = mx + b, and solve for b

15 = 2(4) + b

15 = 8 + b

15 - 8 = b

7 = b

b = 7

The equation would be y = 2x + 7

The y-intercept = 7

f. The y-intercept, 7, is the starting amount, that is the flat fee charged before the cost per pound of weight of a box is added to give total cost of shipping.

Step-by-step explanation:

Totals to 77 minutes after 9:00 am.

answer:

c. just after 10:30 am

explanation:

add 15 + 15

30

+ 8 x 4

30

add 10

30 + 32 + 10 = 72 minutes

plus 5 min with coach

78 minutes

which is just past 10:00 am and to be exact it is 10:18 am

then it takes 15 minutes to get home

so milo gets home just after 10:30 am!

hope this helped <3 also if wouldn't mind could you pls give me brainliest? (im trying to level up) thanks! :)

Answer:

Speed of priya = 2.2 m/s

Mai was faster.

Step-by-step explanation:

Given:

Mai cover 15 meter in 6 second

Priya cover 22 meter in 10 second

Find:

Who was faster

Speed of priya

Computation:

Speed = Distance / time

Speed of mai = 15 / 6

Speed of mai = 2.5 m/s

Speed of priya = 22 / 10

Speed of priya = 2.2 m/s

Mai was faster.

Step-by-step explanation:

its just division

Answer:

Let's define the variables:

M = # of miles that Nora jogs on Monday

T = # of miles that Nora Jogs on Tuesday

We know that:

"Nora jogs 414 miles on Monday"

Then we have:

M = 414 mi

"She jogs 112 fewer miles on Tuesday"

This can be written as:

T = M - 112 mi

This is the equation that we need to solve.

Here we can simply replace the value of M by 414mi and get:

T = 414 mi - 112 mi = 302 mi.

Nora jogs 302 miles on Tuesday.

Answer:the answer is 9 because the height of the triangle is 8^2 (64) and the length is 4^2 (16) add those together and that is 80 then you need to square it which is 8.9 the to the nearest unit which is 9.

Answer:

Total cost= $20.9

Step-by-step explanation:

Giving the following information:

Unitary cost= $0.55

Number of chocolate cupcakes= 38

To calculate the total cost of chocolate cupcakes, we need to use the following formula:

Total cost= unitary cost*number of units

Total cost= 0.55*38

Total cost= $20.9

Step-by-step explanation:

Hοmοzygous means both letters are uppercase, or both are lowercase.

Heterozygous means one is uppercase and the other is lower case.

Dominant is represented by uppercase.  Recessive is represented by lowercase.

"Hοmοzygous dominant" is NN.

"Heterozygous" is Nn.

"Hοmοzygous recessive" is nn.

Shade NN red, and shade Nn green.  Leave nn unshaded.

Answer:

x=3

Let me know if you need an explanation.

Answer:

x = 3

Step-by-step explanation:

Step 1. add 11 to both sides

3x + 4 = 8x - 11

    +11         +11

3x + 15 = 8x

Step 2. subtract 3x from both sides

3x + 15 = 8x

- 3x        -3x

15 = 5x

Step 3. divide by 5 to isolate x

15 = 5x

/5     /5

x = 5

Answer:

9. y= ¼x -5

10. y= 2x +18

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the slope (also known as gradient) and c is the y-intercept.

9. The given equation is already written in the slope-intercept form. The coefficient of x is ¼, thus the gradient of the given line is ¼.

Parallel lines have the same gradient and hence, gradient of line is also ¼.

Substitute m= ¼ into the equation:

y= ¼x +c

To find the value of c, substitute a pair of coordinates.

When x= 8, y= -3,

-3= ¼(8) +c

-3= 2 +c

c= -3 -2

c= -5

Thus, the equation of the line is y= ¼x -5.

10. Gradient of given line= 2

Parallel lines have the same gradient.

Thus, gradient of line= 2

Substitute m=2 into the equation:

y= 2x +c

When x= -4, y= 10,

10= 2(-4) +c

10= -8 +c

c= 10 +8 (+8 on both sides)

c= 18

Therefore, the equation of the line is y= 2x +18.
