Write an algebraic expression for the given statement Add 9z to the product of 3x and 7y

Answer:

24 kilometers

Step-by-step explanation:

1.2 kilometers per minute; 12 kilometers

Step-by-step explanation:

We know that 60 minutes makes 1 hour.

Therefore, to convert the speed to kilometers per minute, we simply divide 72 kilometers per hour by 60 minutes:

72 / 60 = 1.2 kilometers per minute.

Distance is given as speed multiplied by time.

Therefore, in 10 mins, the car travels:

1.2 * 20 = 24 kilometers.

Answer:

260 cities

Step-by-step explanation:

Multiple 5 and 52

James would visit 260 cities in one year.

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Given:

1 year = 52 weeks

James visits 5 cities per week.

To find the number of cities in e one year:

Multiply by 52

52 x 5

= 260 cities.

Therefore, he would visit 260 cities.

Answer:

Step-by-step explanation:

Equation of a line giving 2 points is

y-y1=m(x-x1) where m is the slope and (x1,y1) is one of the points.

First we have to find the slope using formula

(y2-y1)/(x2-x1) where (x1,y1) and (x2,y2) are the points given

Slope m is (4-13)/(8--4) =-9/12 = -3/4

Looking at the answer choices, the only slope intercept equation that use the slope -3/4 is answer choice A

Answer:

F and G are both 112

Step-by-step explanation:

The 4 angles of a trapezoid add up to 360 degrees. Since you already have the two 68 degree angles, add them together to get 136/ Subtract this from 360 to get 224, then divide that by 2 to get the last two angles as 112 degrees each.

Answer: <F = 68˚, <G = 112˚, <H = 112˚

Since the trapezoid is isosceles,  <F = <J = 68˚, and <G = <H. To solve for the remaining angles, we note that the sum of all angles in a quadrilateral is 360˚, so <F + <J + <G + <H = 360˚. Plugging in <F = <J = 68˚, we have <G + <H = 360˚ - 2 × 68˚  = 224˚. Since <G = <H, they are both equal to 224/2 = 112˚.

Answer:

Two angles are called complementary when their measures add to 90 degrees. ∠1 is 60 degrees ∠2 is 30 degrees so if you add it up, the answer is  90 degrees.

∠4 + ∠3 = answer has to be 90 degrees to call it a complementary angle

30 degrees + 60 degrees = 90 degrees

Answer: 26.55°C

Step-by-step explanation:

Average daily maximum temperature in Syracuse = 21.85°C

Average daily minimum temperature = -4.7°C

In order to solve the question, we calculate the difference between the two temperature given. This will be:

= 21.85°C - (-4.7°C)

= 21.85°C + 4.7°C

= 26.55°C

Answer:

  3x + 2y = 0   or   y = -3/2x

Step-by-step explanation:

The relationship between a line and its perpendicular is that their slopes are opposite reciprocals of each other. So, the thing you need to know about the line through the two given points is its slope. That is found using the slope formula:

  m = (y2 -y1)/(x2 -x1) . . . . . . where the two give points are (x1, y1) and (x2, y2)

Putting your point coordinates in this formula gives ...

  m = (5 -3)/(5 -2) = 2/3

Then the perpendicular line will have a slope that is the opposite reciprocal:

  slope of perpendicular = -1/m = -1/(2/3) = -3/2

You have not said whether the perpendicular line must meet any other requirement, so the simplest one we can write is ...

  y = mx + b . . . . . m is the slope and b is the y-intercept

  y = -3/2x . . . . . . has a y-intercept of 0 (goes through the origin)

Multiplying by 2 and adding 3x gives ...

  3x + 2y = 0 . . . . . standard form equation

Comment on the attachment

The geometry program I used to create the attachment wrote the equation of the line through the given points as ...

 2x -3y = -5 . . . . . standard form equation

The equation of a perpendicular line can be created from this form by swapping the x- and y-coefficients and negating one of them. Simply swapping the coefficients would give ...

  -3x +2y = <something>

In standard form, we want the leading coefficient to be positive, so we can choose to negate the x-coefficient. The <something> can be zero to make the line go through the origin.

  3x +2y = 0 . . . . . a perpendicular in standard form

If you need to have the line go through a particular point, you can determine the constant value (on the right of the = sign) by putting the point coordinates in for x and y.

Step-by-step explanation:

A right triangle has leg lengths of 7 inches and 24 inches.

Given

Pythagorean Theorem

For a right-angled triangle with sides 'a' and 'b', the hypotenuse 'c' is

defined as:

[tex]c=\sqrt{a^2+b^2}[/tex]

so substituting the values

[tex]c=\sqrt{7^2+24^2}[/tex]

[tex]c=25[/tex] inches

Thus, the length of the hypotenuse = 25 inches
