Answer 1
Answer:

Answer:

x = 154/13

Step-by-step explanation:

You are given the measures of all three angles in a triangle

so according to the Triangle Sum Theorem:

∠MNO + ∠OMN + ∠NOP = 180

1. Substitute the measures of the angles into the equation:

(3x + 11) + (2x + 20) + (8x - 5) = 180

2. Combine like terms:

(3x + 2x + 8x) + (11 + 20 -5) = 180

13x + 26 = 180

3. Isolate x by subtratcing 26 from both sides

13x + 26 -26 = 180 -26

13x  = 154

4. Solve for x by dividing both sides by 13

13x/13 = 154/13

x = 154/13

the smiths spend 6% of their budget on entertainment. their total budget this year is $1,000 more than last year, this year they plan to spend $2,820 on entertainment. what was their total budget last year?

Answers

Answer: Their total budget last year was $40,000.
Step-by-step explanation:
Given : The Smiths spend 6% of their budget on entertainment.
i.e. , The money they spend on entertainment = 0.06 x ( Total budget)
{ 6% is converted to 0.06 , when we divide it by 100 to remove percentage)
Since , this year they plan to spend $2,580 on entertainment.
i.e. 0.06 x ( Total budget ) = $2,580
On dividing both sides by 0.06 , we get
( Total budget ) = $2,580 ÷ 0.06
= $43,000
Thus , their total budget for this year = $43,000
Also, Their total budget this year is $3,000 more than last year.
Therefore , their last year total budget = ( Total budget this year ) - $3000
= $43,000 - $3000
= $40,000
Hence, their total budget last year was $40,000.

What is the area of this figure.

Answers

Answer: 95cm^2

Step-by-step explanation:

Make smaller shapes then add all the areas up together at the end.

6*4 = 24cm^2

3*2 = 6cm^2

For the base of the triangle:

10+3 = 13cm^2

Area of a triangle = (b*h)/2

(13*10)/2 = 65cm^2

65cm^2 + 13cm^2 + 24cm^2 = 95cm^2

For a client, a landscaper purchases 3 oak trees and 4 maple trees for $380. For his own home, the landscaper purchases 2 oak trees and 5 maple trees for $370. Which augmented matrix represents the situation?

Answers

You don't have any choices here, but it's easy to determine what your matrix would look like by first writing the equations.  Oak trees is x and maple trees is y.  The first of our equations then is 3x + 4y = 380 and the second is 2x + 5y = 370.  In matrix form, that would be \left[\begin{array}{ccc}3&4\n2&5\end{array}\right]=  \left[\begin{array}{ccc}380\n370\n\end{array}\right]

The augmented matrix represents the situation that will be, \left[\begin{array}{ccc}3&4\n2&5\n\end{array}\right].

What is an augmented matrix?

The columns of two matrices are combined to create a new matrix known as an augmented matrix.

When using matrices to solve straightforward linear equations, the augmented matrix is a crucial tool. The number of variables in the linear equation is the same as the number of rows in the augmented matrix.

Let us consider x is the oak tree and y is the maple tree then;

⇒3 oak trees and 4 maple trees for $380;

⇒3x+4y = 370

Purchases 2 oak trees and 5 maple trees for $370;

⇒2x+5y=370

The two equations are expressed in the matrixas;

\left[\begin{array}{ccc}3&4\n2&5\n\end{array}\right]

Hence, the augmented matrix represents the situation that will be, \left[\begin{array}{ccc}3&4\n2&5\n\end{array}\right].

What is the x-intercept of the line with the equation 4x + 2y = 12?A. (0, 6)
B. (6, 0)
C. (0, 3)
D. (3, 0)

Answers

x intercept is where the line crosses the x axis or where y=0
set y=0

4x+2(0)=12
4x+0=12
4x=12
divide by 4
x=3

(x,y)
(3,0)

D is answer

Answer:

Option (d) is correct.

The x- intercept of the line with the given equation of  4x + 2y = 12 is (3,0)

Step-by-step explanation:

Given : Equation of  line 4x + 2y = 12

We have to find the x- intercept of the line with the given equation of  4x + 2y = 12 and choose the correct option from the given equations.

Consider the given equation  4x + 2y = 12  

x intercept is defined as a point where the line cuts y axis that is where point y is 0.

Put y = 0 , we have,

4x + 2(0) = 12

4x = 12

Divide both side by 4, we get,

x = 3

Thus, the x intercept of the line with the given equation of  4x + 2y = 12 is (3,0)

If √6 is the geometric mean between 4 and another number, then the number is

Answers

If you have two numbers x, y.  The geometric mean is:  √xy

For 4 and x.  Geometric Mean =  √4x  and this is equal to √6

             √4x  =  √6     Square both sides.  The square root disappears.

               4x = 6 
                 x  = 6/4 = 3/2 = 1.5

The other number is 1.5.
