Step-by-step explanation:

Since she ran 12 miles in 4 days, and all of them were equal, divide 12 by 4. Answer is 3 ^^

Answer:

350 days

Step-by-step explanation:

If Ravi is eliminating 100 calories per day, and one pound of body fat is 3500 calories, then it will take him 35 days to lose one pound of body fat.

Multiply 35 by 10 to find how long it will take for him to lose 10 pounds:

35(10)

= 350

So, it will take him 350 days to lose 10 pounds.

Answer:

350

Answer:

13.4 x 2 = 26.8

12.5

HYPOTENUSE:

10^2 + 12.5^2 = 256.25

Square root of 256.25 = around 16

which would equal 256

16 is your hypotenuse.

26.8 + 12.5 + 16 = 55.3 is your perimeter

Answer: 90

Step-by-step explanation:

450/5 or 450 divided by 5

you can work this out by figuring out 45/5 which is 9

so 450/5 equals 90

he should read 90 pages per day

Answer:

90

Step-by-step explanation:

Because if you divide the pages into the 5 day it would be 90

450 divide by 5 = 90

Step-by-step explanation:

Answer:

The Pythagorean Theorem leads to a simple proof of the Pythagorean Identity using only the basic definitions of trig functions. The Pythagorean Theorem on a right triangle with legs a,b and hypotenuse c gives us: a2+b2=c2. Dividing through by c2 gives: (ac)2+(bc)2=1.

Answer:

Pretty sure your teacher means sin²x+cos²x=1

Step-by-step explanation:

There's the Pythagorean identity sin²x+cos²x=1 if that's what you mean

Answer:

15

Step-by-step explanation:

hypotenuse (h) = 25

perpendicular (p) = 20

base (b) = ?

we know by using Pythagoras theorem we get

b = √h² - p²

  = √25² - 20²

  = √225

  = 15

Answer:

650 cm²

Step-by-step explanation:

Use the formula 2(lw+wh+lh)

Plug in the stuff: 2(5*9+9*20+5*20)=2(45+180+100)=2(325)=650 cm²

And there you go!

As we are getting the 25% from the whole population of 380 students, therefore this is a population proportion which is a parameter. Note that we get parameter from population and statistic from the sample.

Step-by-step explanation:

The property parameter describes the number, 25% because  25% from a population of 380 students, this is a population proportion that may be used as a metric option (D) parameter is correct.

It is described as a collection of data with the same entity that is linked to a problem. The sample is a subset of the population, yet it is still a part of it.

We have:

Number of samples = 40

30% of them have period 4 lunch.

Total population = 380

25% of them have period 4 lunch.

Because we're collecting 25% from a population of 380 students, this is a population proportion that may be used as a metric.

We collect parameters from the population and statistics from the sample.

Thus, the property parameter describes the number, 25% because  25% from a population of 380 students, this is a population proportion that may be used as a metric option (D) parameter is correct.

Step-by-step explanation:

Answer:

c

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

- 4x + 3y = 12 ( add 4x to both sides )

3y = 4x + 12 ( divide the terms by 3 )

y = [tex]\frac{4}{3}[/tex] x + 4 ← in slope- intercept form

with slope m = [tex]\frac{4}{3}[/tex] and y- intercept c = 4

---------------------------------------------------

Given

- 5x + 3y = - 9 ( add 5x to both sides )

3y = 5x - 9 ( divide the terms by 3 )

y = [tex]\frac{5}{3}[/tex] x - 3 ← in slope- intercept form

with slope m = [tex]\frac{5}{3}[/tex] and y- intercept c = - 3

Answer:

-42

Step-by-step explanation:

Following Order of Operations, we have to multiply before subtracting, so

[tex]2-2*22[/tex]

[tex]=2-44[/tex]

[tex]=-42[/tex]

Using order of operations, we get -42.

Answer:

Given no. of persons owned laptop = 76

Total of no. of students owned + Total of no. of students dont have owned laptop given = 155

No. of students dont have laptops = 155 - 76 = 79

So then the total no. of no laptops = 79 + 17 = 96(ans)

Answer: I just did the test so the answer is A. 5.8 units

Step-by-step explanation: hope this help thx for the points :D

Length of QR in units = 5.83 units, which is closest to 5.8 units.

The correct option is A.

The distance between any two points is the length of the line segment joining the points.

The formula for the distance, D, between two points whose coordinates are (x₁, y₁) and (x₂, y₂)

D = √((x2 – x1)² + (y2 – y1)²)

This is called the Distance Formula.

Given,

Coordinates of points Q (8, 2) and R (5, 7)

Length of QR = Distance between point Q and point R.

D = √((x2 – x1)² + (y2 – y1)²)

D = √((5 - 8)² + (7 - 2)²)

D = √(-3² + 5²)

D = √9 + 25

D = √34

D = 5.83 units

Length of QR rounded to one decimal = 5.8 unit

Hence, 5.8 unit is closest to the length of QR = 5.83units

Answer:

x>-1

Step-by-step explanation:

So, we want to isolate the variable which is X. To do so, we must add 4 on both sides.

x-4+4>-5+4

x>-1

Next comes the graphing:

This equation means that x can be all values that are LARGER THAN -1. The line would start from -1, but it wouldn't include negative one, and stretch all the way to positive infinity (to the right).

Answer:

common form to write the equation of a circle in is the center-radius form. The center-radius form is: (x−h)2+(y−k)2=r2 Here, the center point is denoted by (h,k) and r is the radius of the circle. The first example he does is: Find the center and radius of the circle given by the equation (x−2)2+(y+4)2=25.

Answer:

x² + y² = 16

Step-by-step explanation:

We need to write the standard equation of circle with , centre (0,0) and radius 4 unit . The Standard equation of the circle ⭕ is ,

=> ( x - h)² + (y -k)² = r²

=> ( x -0)² + (y-0)² = 4²

=> x² + y² = 16 .

• Hence the equation of the circle is x² + y² = 16.
