Write the equation of the line that passes through the points (4,5) & (-3, -1)

Answers

Answer:

y=6/7x+11/7

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-5)/(-3-4)

m=-6/-7

m=6/7

y-y1=m(x-x1)

y-5=6/7(x-4)

y=6/7x-24/7+5

y=6/7x-24/7+35/7

y=6/7x+11/7

Find the perimeter. The shape consists of a square and a half circle. Solve​

Answers

Answer and Step-by-step explanation:

We have 3 sides of a square on the outside, so 2 + 2 + 2 equals 6. This is part of the perimeter.

Now we find the circumference of half the circle.

Radius of 1, So the circumference for half of this circle is pi, or 3.14.

So, the answer is 3.14 + 6, which equals 9.14.

The perimeter of the shape is 9.14.

Jessica has saved $50. She will add $25 to her savings each week. Ron has saved $40 and will add $25 to his savings each week.



How much will each person have saved after 5 weeks?

Answers

Answer:

Jessica will have saved $175, and Ron will have saved $165.

Step-by-step explanation:

Jessica starts out with $50. She adds $25 each week, and it's asking how much money she would have in 5 weeks. So, you multiply $25 by 5 to get $125. Then, you add $50 to that to get $175. Same thing for Ron. Multiply $25 by 5 to get $125, but this time add $40 to it to get $165.

Answer:

Jessica- $175

Ron- $165

Step-by-step explanation:

Jessica starts with $50 so put that aside and then it says that she adds $25 EVERY WEEK so how much is she going to have in 5 weeks? 5 x $25 is $125 and now add the $50 which will equal $175

In Ron is the same thing but rather than adding $50 add $40 and it will equal $165

What is the value of x? Answer must be in decimal form 1.5x + 4 = 2.3x - 1.2
I need help

Answers

Answer:

x = 6.5

Step-by-step explanation:

1.5x - 2.3x + 4 = 1.2

1.5x - 2.3x = -1.2 - 4

-0.8x = - 1.2 - 4

-0.8x = -5.2

divide both sides of the equation by -0.8

x = 6.5   :)

Step-by-step explanation:

A basketball game court is 94 feet long and 50 feet wide. Ryan used long steps to estimate the length of the court as 93 feet and width 48 feet. What is the percent error of ryan's measured area round your answer to the nearest hundred.

Answers

Sorry if you don’t get it right but I think it’s going to to be 5.02

The percent error of Ryan's measured area is 0.04%.

How to calculate the percent error?

To calculate the percent error of Ryan's measured area, you need to subtract his measurement from the actual value and divide that by the actual value, and then multiply by 100 to express the result as a percentage.

First, find the difference between the actual value and Ryan's measurement: 94 feet - 93 feet = 1 foot for the length, and 50 feet - 48 feet = 2 feet for the width.

Then, multiply these values to find the difference in the area: 1 foot × 2 feet = 2 square feet.

Then, divide the difference in the area by the actual area and multiply by 100 to express the result as a percentage:

(2 square feet / (94 feet × 50 feet)) × 100 = 0.04255%.

Rounded to the nearest hundred, the percent error is 0.04%.
