Answer:

k = 2.5

Step-by-step explanation:

We know that,

y = kx

=> y/x = k

Let us take the first value of x and y.

Si, 5/2 = k

=> 2.5 = k

Note: We can take any of the given values of x and y from the table.

Find the area of the rectangle with the given base and height.
13 ft, 2 in

Answers

Answer:

Area of rectangle = 2.16 [tex]ft^{2}[/tex]

Step-by-step explanation:

Given ,

Base = 13 ft = 156 in

Height = 2 in

Area of rectangle = base * height

area = 156 * 2

area = 312 [tex]in^{2}[/tex]

area in square foot = [tex]\frac{312}{144}[/tex] = 2.16 [tex]ft^{2}[/tex] approx

what is the perimeter of the trapezoid

Answers

Answer: 25.66 units

Step-by-step explanation:

AB = 8

DC = 12

Distance between point D and A

D=sqrt[(-3 - - 5)^2 + (4 - 2)^2

= sqrt (2^2 + 2^2)

= 2 sqrt 2 = 2.83

AD = 2.83

BC = 2.83

2 (2.83) + 8 + 12 = 25.66 units

Write the equation of the line perpendicular to 2x-5y=-12 that passes through the point (10,-1) in slope-intercept form.

Answers

Answer:

[tex]y=-\frac{5}{2}x-24[/tex]

Step-by-step explanation:

[tex]2x-5y=-12\\5y=2x+12\\y=\frac{2}{5}x+\frac{12}{5}\\[/tex]

if two lines perpendicular,

[tex]m_{1} .m_{2}=-1\\ \frac{2}{5} .m_{2}=-1\\m_{2}=-\frac{5}{2}[/tex]

the line perpendicular to this line is

[tex]y=-\frac{5}{2}x+k[/tex] ; k ∈ R

the line passes through the point (10,-1)

so,

[tex]-1=-\frac{5}{2} (10)+k\\-1=-25+k\\k=-24[/tex]

∴the equation of the line perpendicular to 2x-5y=-12 that passes through the point (10,-1) is

[tex]y=-\frac{5}{2}x-24[/tex]

If tom had 557 oranges and Billy had 676 more oranges than tom. How many oranges does Billy have.

Answers

Answer:

billy has 1233 oranges

Step-by-step explanation:

557+676=1233

you add 557 and 676 to figure out how much billy has

you can check your answer by subtracting 1233-557=676

Answer:

Billy has 1233 oranges.

Step-by-step explanation:

This is a simple, they have this many more than this person has, so an example is the B has 1 book, but Alex has a book collection of 10 books. They both have more than one book, but Alex has 10 books in total, with 9 more than B does.

So, for this question, Tom has 557, and Bill had 676 more than him, so that would mean you need to add 676 and 557 together to get 1233 oranges for just Billy. So that would be our answer.

Hoshi walks 12 meters in 3 seconds.
What is her walking rate?

Answers

Answer:

Step-by-step explanation:

To calculate the walking rate, you have to think of the unit that the walking rate is in. Walking rate is most often in meters per second or kilometres per hour, so I'll explain both. The first one (m/s) is easy, since both are already in these units. The formula speed = distance/time can be used here, which gives 12/3 = 4 meters per second.

For km/h it is a little more difficult. 12 meters equals 12/1000 kilometers (which is 0.012), since there are 1000 meters in a kilometer. Then 3 seconds equals 3/60 minutes (which is 0.05 mins), which is 0.05/60 hours (which is 0.0083333). Using the formula now, the answer is 0.012/0.0083333 = 14/4 km/h

A cereal manufacturer has a tolerance of 0.75 oz for a box of cereal that is supposed to weigh 20 oz. Determine the compound inequality solution that describes the acceptable weights for a 20 oz box.

Answers

I hope it helps you

An compound inequality that describes the acceptable weights for a 20 oz box is 19.25 ≤ x ≤ 20.75.

What is an absolute value?

The absolute value of a number is defined as its magnitude irrespective of the sign of the number. To determine the absolute value of a real number, we consider only the number and remove the sign. It can only be a non-negative value.

We are Given that, cereal manufacturer has a tolerance of 0.75 oz for a box of cereal that is supposed to weigh 20 oz.

Let the weight of cereal box be; w

Now, the inequality is

20-0.75 ≤ x ≤ 20+0.75

Add 20 on both sides of an inequality, we get

19.25 ≤ x ≤ 20.75

Here, 19.25 ≤ x ≤ 20.75

Therefore, an absolute value inequality to find the range of acceptable weights is 19.25 ≤ x ≤ 20.75.
