Answer:

Alicia

Step-by-step explanation:

First, convert the mixed fractions into improper fractions

Alicia

Distance: 5 1/2 = 11/2 = 5.5 miles

Time: 1 2/5 = 7/5 = 1.4 hours

Carlos

Distance: 8 1/8 = 65/8 = 8.125 miles

Time: 2 1/2 = 5/2 = 2.5 hours

Henry

Distance: 3 2/3 = 11/3 = 3.6 reoccuring miles

Time: 1 1/10 = 11/10 = 1.1 hours

Zoe

Distance: 4 2/3 = 14/3 = 4.6 reoccuring miles

Time: 1 3/10 = 13/10 = 1.3 hours

After that, divide the distance by the time

Alicia = 5.5 / 1.4 = 3.93 ( 3 s.f )

Carlos = 8.125 / 2.5 = 3.25

Henry = 3.6 re / 1.1 = 3.3 reoccuring

Zoe = 4.6 / 1.3 = 3.54 ( 3 s.f )

Looking at these answers, we determine which rate is the greatest

Alicia = 3.93

Carlos = 3.25

Henry = 3.3 re

Zoe = 3.54

Alicia hiked the highest rate.

Graph the line that passes through the points (3, -6) and (4, - 7) and determine the equation of the line.​

Answers

Answer:

y=-x-3

I attached a file so you can plot the points on your own.

Answer:

Step-by-step explanation: First we need to figure out the slope. There are two ways:

Slope Intercept form:

First you need to find the slope with Δy/Δx. This will plug in as

-7 - (-6)/ 4 - 3. This will simplify to -1/1, then -1. So m = -1

Now we have the equation y = -1x + b. We need to find b.

In order to do that, we need to plug in one of the points. I'm using (3,-6) but you can use whatever point. Once we plug it in, we have -6 = -(3) + b. Solve for b and you get -3. So the final equation is y = -x - 3.

Point Slope form:

Like the slope intercept form, we need to find the slope, in which case is -1. Next, we can use one of the ordered pairs again to plug it into the equation

y -  [tex]y_{1}[/tex] = m(x - [tex]x_{1}[/tex]), where [tex]y_{1}[/tex] is the y of the pair and [tex]x_{1}[/tex] is the x of the pair. You can use the other points too. The final equation once you plug it in is y -(-6) = -(x-3) or y + 7 = -(x - 4).

jayden wats to use square pavers that 4 inhes on each side to completely surroung his flower garden the gaen is 8 ft long and 2 feet wide. how manyu pavers should jaden buy

Answers

The number of pavers is the count of pavers that fit the garden

Jayden should buy 1 paver

The dimension of the garden is given as:

Length = 8ft

Width = 2ft

So, the area is calculated as:

Area = Length x Width

This gives

Area = 8ft x 2ft

Area = 16 square ft

The dimension of the paver is given as:

Length = 4ft

So, the area is calculated as:

Area = Length x Length

This gives

Area = 4ft x 4ft

Area = 16 square ft

The number of pavers is calculated by dividing the area of the garden by the area of the pavers.

So, we have:

[tex]\mathbf{Number = \frac{Garden}{Pavers}}[/tex]

[tex]\mathbf{Number = \frac{16ft^2}{16ft^2}}[/tex]

[tex]\mathbf{Number = 1}[/tex]

Hence, he should buy 1 paver

Eduardo is in 8th grade and gets an allowance of $10 every week from his parents. He has saved up $110 so far in a savings account. He wants to buy some new clothes since his current wardrobe is getting worn out. He sets a budget of $250 for himself.

a: How much more money does Eduardo need before he can go shopping?

b: How many months will it take Eduardo to save this much money?

c: What trade offs might Eduardo need to make if he wants to buy the clothes in exactly 3.5 months?

Answers

Answer:

He has. saved up $110 so far in a savings account. He wants to buy some new clothes since his current wardrobe is getting worn out.

Step-by-step explanation:

a. Eduardo needs $140 more before he can go shopping.

b. 3.5 months will it take Eduardo to save this much money.

c. Eduardo will need to make thoughtful decisions about how he manages his money and balances his spending with his savings goal.

a. Here, we have to find out how much more money Eduardo needs before he can go shopping, we need to calculate the difference between his budget and the amount he has saved:

Remaining money needed = Budget - Saved amount

Remaining money needed = $250 - $110

Remaining money needed = $140

So, Eduardo needs $140 more before he can go shopping.

b. To determine how many months it will take Eduardo to save $140, we can divide the remaining amount by his weekly allowance:

Number of weeks to save $140 = Remaining money needed / Weekly allowance

Number of weeks to save $140 = $140 / $10

Number of weeks to save $140 = 14 weeks

Since there are approximately 4 weeks in a month, we can convert weeks to months:

Number of months = Number of weeks / 4

Number of months = 14 weeks / 4

Number of months = 3.5 months

c. If Eduardo wants to buy the clothes in exactly 3.5 months, he will need to consider some trade-offs to meet his savings goal on time:

Cutting Expenses: Eduardo might need to cut down on unnecessary expenses, like snacks or entertainment, to save more money each week.

Additional Income: He could explore opportunities to earn extra money, such as doing chores or odd jobs for neighbors, to supplement his allowance.

Delayed Purchases: Eduardo could delay spending money on non-essential items until he reaches his savings goal. This might mean postponing purchases that can wait.

Adjusting Budget: Eduardo could reconsider his budget to see if there are any areas where he can reduce spending further to meet his goal faster.

Savings Prioritization: Eduardo could prioritize his savings over other purchases and activities for the next 3.5 months.

Ultimately, Eduardo will need to make thoughtful decisions about how he manages his money and balances his spending with his savings goal.

Find area of the triangle formed by x− and y−intercepts of the parabola y=4x^2−8x−5.

Answers

Answer:

7.5 unit square

Step-by-step explanation:

7.5 unit²

Step-by-step explanation:

Refer to attached

Find the y-intercept:

x = 0 ⇒ y = 4*0 - 8*0 - 5 = - 5

Find the x-intercepts:

y = 0 ⇒ 4x² - 8x - 5 = 0

4x² - 8x + 4 - 9 = 0

4(x - 1)² = 9

(x - 1)² = 9/4

x - 1 = 3/2 ⇒ x = 2.5

x - 1 = - 3/2 ⇒ x = - 0.5

We have vertices of the triangle at:

(- 0.5, 0), (2.5, 0) and (0, -5)

Base of the triangle is:

2.5 - (-0.5) = 3

Height of triangle:

0 - (-5) = 5

The area is:

A = 1/2bh

A = 1/2*3*5 = 7.5

Answer:

7.5 unit²

Step-by-step explanation:

find x and y intercepts

x = 0 ⇒ y = 4*0 - 8*0 - 5 = - 5

y = 0 ⇒ 4x² - 8x - 5 = 0

4x² - 8x + 4 - 9 = 0

4(x - 1)² = 9

(x - 1)² = 9/4

x - 1 = 3/2 ⇒ x = 2.5

x - 1 = - 3/2 ⇒ x = - 0.5

We have vertices of the triangle at:

(- 0.5, 0), (2.5, 0) and (0, -5)

Base of the triangle is:

2.5 - (-0.5) = 3

Height of triangle:

0 - (-5) = 5

The area is:

A = 1/2bh

A = 1/2*3*5 = 7.5


Here is a picture of two squares and a circle. Use the picture to explain why
the area of this circle is more than 2 square units but less than 4 square units.

Answers

Answer: This is so because, the circle does not totally cover the area defined by the four squares and this is evident in the workings below.

The area of a square is; Area = l²

Since each circle has area, A = 1 square unit.

Therefore,

Length of Each side of each square = 1 unit

This in turn is the radius of the circle given;

The area of the circle is therefore, Area = πr²

Area = (22/7) × 1²

Area = 3.142 square units

In essence, the area of the circle is less than 4 square units.

A.) In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality.
B.) In both cases, divide by -3 on both sides, but reverse the inequality sign when doing that for the inequality.
C.) The process is exactly the same for solving the equation and solving the inequality.
D.)The process for solving the equation is entirely different from solving the inequality.​

I believe it's A) "In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality."

Step-by-step explanation:

I say this because that's essentially the first step when solving both an equation and inequality.

(In case you were wondering, the next step would be to divide -3 on both sides, in order to get x by its self.)

Seeing that the radius is 2m, we also see that the diameter is 4m. Looking at the picture, the height of the triangle is also 4m. Given that the shape around the circle is a square, we now know the dimensions of the square is 4m x 4m. Knowing that a triangle with such symmetry is half the area of the square, we calculate it as (4 x 4) / 2 = 8m^2, which is your answer.
