Answer:

6:30 would be the ratio cause out of 30 cars 6 are SUVs

Answer:

A= -40

B= 16

C= 40

D= 50

Step-by-step explanation:

The values of the matrix is a = -40, b = 16, c = 40, d = 50.

A matrix is an arrangement of numbers, expressions or symbols arranged in rows and columns as a rectangular array. These rows and columns define the size or dimension of a matrix.

For the given situation,

The matrix is

[tex]\left[\begin{array}{ccc}4&-1&-4\\0&5&-2\\0&8&10\end{array}\right] = \left[\begin{array}{c}-7&-11&22\end{array}\right][/tex]

The operation on matrix is

[tex]-8R2- > R2[/tex] and

[tex]5R3- > R3[/tex]

⇒ [tex]\left[\begin{array}{ccc}4&-1&-4\\0&-40&16\\0&40&50\end{array}\right] = \left[\begin{array}{c}-7&88&110\end{array}\right][/tex]

On comparing this equation with the given equation,

[tex]a=-40, b=16, c=40, d=50[/tex]

Hence we can conclude that the values of the matrix is a = -40, b = 16,     c = 40, d = 50.

Answer:

  y = -4x +9

Step-by-step explanation:

The same slope-intercept equation can be used, but with a different y-intercept. That new y-intercept can be found from the given point (x, y) using the formula ...

  b = y -mx

  b = 5 -(-4)(1) = 9

So, the equation with the new y-intercept is ...

  y = -4x +9

The distance that the base of the telephone pole to point B where the guy wire is secured to the ground is 57.7 feet

Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.

Given that triangle ABC is a right triangle.

Point A is the top of the telephone pole.

Point B is the point on the ground.

Point C is the base of the telephone pole.

Given,

AB = 79 feet

AC is the height of the telephone pole = 54 feet

Angle C is a right angle.

Using Pythagoras theorem,

(AB)² = (AC)² + (BC)²

79² = 54² + (BC)²

(BC)² = 79² - 54²

(BC)² = 3325

BC = √3325 = 57.66 ≈ 57.7 feet

Hence the length of the base of the pole form the ground where the wire is secured is approximately 57.7 feet.

Answer and explanation:

Cable tv cost changed by $67-$55= $12= 12/55×100=21.818%

Cable TV cost increased by 21.818% of original cost

Dozen of eggs cost changed by $2.19-$1.79= $0.4= 0.4/1.79×100= 22.636%

Dozen of eggs cost increased by 22.636% of original cost

Therefore both customers can't be correct, cost of a dozen of eggs increased the most.

m=-6

Step-by-step explanation:

-m + 8 = -4m -10

+m. +m.

8= -3m -10

+10. +10

18 = -3m

/-3m /-3m

-6=m

Answer:

m=-6

Step-by-step explanation:

–m + 8 = –4m − 10

Subtract 8 from both sides

-m+8-8=-4m-10-8

Simplify:

-m=-4m-18

Add 4m to both sides

-m+4m=-4m-18+4m

Simplify:

3m=-18

Divide both sides by 3

3m/3=-18/3

-18/3=-6

m=-6

Isosceles triangle.

Step-by-step explanation:

On the basis of the lengths of the sides of a triangle, below are three types of triangles.

Equilateral triangle: The triangle in which the lengths of all sides are equal.

Isosceles triangle: The triangle in which the lengths of any two sides are equal.

scalene triangle: The triangle in which the lengths all the three sides are different.

Here, the length of the sides are 24 24 and 4.

Since, two sides are equal in length.

Hence, it is an Isosceles triangle.

Is the line at the bottom of question 3 the right side or left?

Answer:

Youu can call the breadth x and then, as the length is two times the breadth, it would be 2x.

So now when we call x to the breadth and 2x to the length we can do an equation, as we know the sum of the four sides is 300 meters, so

2x + 2x + x + x = 300

6x = 300

x = 300/6 = 50

We know that the breadth is 50m, and, the length, which is twice the breadth, would be 100m in this exercise.

SO in this case, the breadth is 50 meters and the length is 100 meters..

Answer:

9 cookies

Step-by-step explanation:

The equation is 11.1 = 0.9x + 3. First, we need to isolate the variable so we subtract 3 from both sides. 8.1 = 0.9x. Next we divide both sides by 0.9 which gives us 9 = x or x = 9.
