Jeremy drew out the route he will hike over a 3-day period on the coordinate grid below. He will hike from Point A to Point B and from Point B to Point C on the first two days. On day 3, he will hike directly from Point C to Point A.

If each grid unit represents a distance of 1 mile, what is the distance Jeremy will need to travel between Point C and Point A?

Answers

The distance Jeremy will need to travel between Point C and Point A 19.69 miles.

Jeremy drew out the route he will hike over a 3-day period on the coordinate grid below.

He will hike from Point A to Point B and from Point B to Point C on the first two days.

On day 3, he will hike directly from Point C to Point A.

We have to determine the distance Jeremy will need to travel between Point C and Point A.

What is the distance formula?

[tex]d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}[/tex]

d = distance

(x_1, y_1) = coordinates of the first point

(x_2, y_2) = coordinates of the second point

(4,9)=(x_1,y_1)

(-4,-9)=(x_2,y_2)

[tex]d = \sqrt{(-4 - 4)^2 + (-9-9)^2}\\d=\sqrt{(8)^2+(18)^2} \\d=2\sqrt{97}\\ d=19.69[/tex]

Therefore, The distance Jeremy will need to travel between Point C and Point A 19.69 miles.

It takes you 3 hours to drive to a concert 135 miles away. You drive 55 miles per hour on highways and 40 miles per hour on the rest of the roads. Write a system of linear equations that represents this equation. Use x to represent the number of hours driving on a highway and y to represent the number of hours driving on other roads.

Answers

Answer:

x + y = 3  (1)

55x + 40y = 135 (2)

Step-by-step explanation:

Since  x to represent the number of hours driving on a highway and y to represent the number of hours driving on other roads and the total time for driving is 3 hours,

x + y = 3  (1)

Also, You drive 55 miles per hour on highways and 40 miles per hour on the rest of the roads, the distance moved on highways is 55x and the distance moved on the rest of the roads is 40y (since distance = speed × time).

Since the total distance moved is 135 miles, we have

55x + 40y = 135 (2)

So, the system of linear equations that represent the situation is

x + y = 3  (1)

55x + 40y = 135 (2)

Savannah bought barn wood for $60 for 5 pieces. She spent $40 on materials to paint
and design the decorations. She sells each piece of wood for $25. What is her
profit/loss?

Answers

her profit per each wood is $5 so her total profit is $25

because
60 divided by 5 is 12, so each wood is 12 dollars
she spent 40 dollars on materials so 40 divided by 5 is 8, so she spent $20 on each piece of wood to paint it because 12(price of wood)+8(cost of materials per wood)= 20
and shes sells them for 25
so 25-20=5
5x5=25
so the answer is $25 profited

Answer:

Y= -5/2x+3

Step-by-step explanation:

A perpendicular slope is always opposite (meaning if the original is negative, then it is positive and vice versa) and reciprocal (meaning the numerator and denominator of the original are flipped).

The y intercept I found by applying the slope to the point given.

Perpendicular lines have opposite reciprocal lines.

y = mx + b
the m represents the slope
the opposite reciprocal of 2/5 is -5/2
y = -5/2x + b
to solve the rest of the problem, you will need to plug in your x and y coordinates.
-2 = -5/2(2) + b
-2 = -10/2 + b
-2 = -5 + b
Add 5 to both sides.
b = 3

This means your equation is...
y = -5/2x + 3

An architect has designed a new hotel shaped like a giant rectangular pyramid. The base of the model for this hotel measures 20 inches by 30 inches, and is 25 in. tall. What is the volume of the pyramid?

Answers

Answer:

Volume of pyramid = 5000 cubic inches.

Step-by-step explanation:

Given the following data;

Length = 20 inches

Width = 30 inches

Height = 25 inches

To find the volume of pyramid;

Mathematically, the volume of a pyramid is given by the formula;

[tex] Volume = \frac {1}{3} * base \; area * height [/tex]

First of all, we would determine the base area;

Base area = length * width

Base area = 20 * 30

Base area = 600 in²

Substituting into the formula, we have;

[tex] Volume = \frac {1}{3} * 600 * 25 [/tex]

[tex] Volume = 200 * 25 [/tex]

Volume of pyramid = 5000 cubic inches.

If y varies directly with x and y = 84 when x = 12, find y when x = 11.

Answers

Answer:

y= 77

Step-by-step explanation:

Write down the equation for direct proportion.

y= kx, where k is a constant.

Find the value of k.

When x= 12, y= 84,

84= k(12)

12k= 84

k= 84 ÷12

k= 7

Substitute the value of k into the equation.

y= 7x

When x=11,

y= 7(11)

y= 77

1. Jemima wants to make chocolate chip walnut brownles. Chocolate chips come in a 12oz bag that costs $3. Walnuts
come in a 4oz bag that costs $2. If Jemima needs three pounds of chocolate chips and walnuts combined, and has $15
to spend, how many bags of each can she buy?

Answers

Answer:

4 bags of chocolate chips and 1 bag of walnuts.

Step-by-step explanation:

Find how many ounces are in 3 pounds:

16 oz = 1 lb

16 oz × 3 = 3 lbs

48 oz = 3 lbs

Variable x = number of chocolate chips

Variable y = number of walnuts

4x + 1y = 15

Keep in mind it must equal up to 48 oz and be $15 or under.

4 bags × 12 oz = 48 oz

1 bag × 4 oz = 4 oz

48 oz + 4 oz = 52 oz > 48 oz

4 bags × $3 = $12

1 bag × $2 = $2

$12 + $2 = $14 < $15

Both requirements have been met.
