Estimate 73% of 23.95

Answer:

$360

Step-by-step explanation:

Calculation for what would be the total cost of next month's order

First step is to calculate how much they paid per the two cases of printer papers

Two cases of printer paper=$48 /2

Two cases of printer paper=$24 per case

Second step is to calculate the cost of each package of printer paper

Cost of each package of printer paper=$24/12 packages of paper

Cost of each package of printer paper=$2

Last step is to calculate the total cost of next month's order

Total cost=180 packages*$2

Total cost=$360

Therefore what would be the total cost of next month's order is $360

Answer:

8/10 or 4/5 (simplified)

Step-by-step explanation:

3/5      >      6/10   (x2 by numerator and denominator to match with 7/10)

6/10 + 7/10 = 13/10

13/10 - 1/2      >      13/10 - 5/10 = 8/10

8/10 or 4/5 (simplified)

Step-by-step explanation:

When dividing/multiplying you flip the inequality sign, and the negative on the x and 2 cancel.

Answer: $38.50

Step-by-step explanation: Find 70% of $55.

Answer:

38.5

Step-by-step explanation:

SO U FIND 10% WHICH IS =5.5

THEN U TIMES IS BY 3 AND ITS =16.5

THEN YOU MINUS 55 BY 16.5

AND THAT IS =38.5

Answer:

27x+49

Step-by-step explanation:

1. Start by distributing the 5 to 6x+9. This means to multiply 6x and +9 by 5.

6x times 5 = 30x

5 x 9 = 45.

5(6x+9) simplifies to 30x+45

2. Rewrite the expression as 30x+45-3x+4

3. Combine like terms.

30x - 3x = 27x

45 + 4 = 49

27x+49

Answer:

114 yards

456 yards

Step-by-step explanation:

Given that:

Area of square parking lot = 12,996 square yards

The lenght of one side of the parking lot :

Area of a square = a² ; a = side length

Hence ;

12996 = a²

√12996 = a

114 = a

Hence, length of one side = 114 yards

Yards of fence needed to enclose parking lot :

Perimeter of a square = 4a ; a = side length

Perimeter = 4(114)

Perimeter = 456 yards

Answer:

A

Step-by-step explanation:

A. 3 x 18 = 54

B. 6 x 21 = 126

C. 9 x 24 = 144

D. 18 x 33 = 594

Answer:

sales tax is $3.50.

She would have to pay $73.50

Step-by-step explanation:

5% of 70 is 3.5 (sales tax)

70+3.5= 73.5

Answer:

-1/2

Step-by-step explanation:

The equation for slope is y2 - y1 and x2 - x1. So you do 5(y2) - 4 (y1) which is 1. And 6(x2) - 8(x1) which is -2. Put 1 as the numerator and -2 as the denominator as you got -1/2. The fraction is negative because the -2 made it that way

Answer:

0.29

Step-by-step explanation:

12 divide by $3.48 is 0.29

Answer:

A 8.565 < l-13.23l

Step-by-step explanation:

Because the brackets makes the -13.23 positive

Step-by-step explanation:

The absolute maximum of the function is y = 4, at (3, 4).

Both ends of the function point downward, which stretches to negative infinity.

Hence the range is -infinity < y <= 4. (D)

Answer:

48

Step-by-step explanation:

If there were 126 students total, and 21 dots. That means that there are 6 students per dot. And since there are 8 dots in the 18 minute mark, that means that there were 48 predicted students.

Please check the explanation.

Step-by-step explanation:

                                           6)

Given the line

[tex]y=-\frac{1}{3}x+3[/tex]

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

where m is the line and b is the y-intercept

Thus, the slope of line = -1/3

We know that parallel lines have the same slope.

Hence, the slope of the parallel line is also m=-1/3

So, substituting m = -1/3 and (3, 1) in the slope-intercept form to find the y-intercept

[tex]y=mx+b[/tex]

[tex]1=\frac{-1}{3}\left(3\right)+b[/tex]

Switch sides

[tex]\frac{-1}{3}\left(3\right)+b=1[/tex]

[tex]-1+b=1[/tex]

[tex]b=2[/tex]

Thus, the equation line in slope-intercept form

[tex]y=mx+b[/tex]

[tex]y=-\frac{1}{3}x+2[/tex]

                                             8)

Given the line

[tex]y=\frac{1}{4}x+1[/tex]

We know that the slope-intercept form of the line equation is

[tex]y=mx+b[/tex]

where m is the line and b is the y-intercept

so the slope of line = 1/4

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so

The slope of the perpendicular line will be: -4

Thus, subtituting m = -4 and (-1, 4) in the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-4=-4\left(x-\left(-1\right)\right)[/tex]

writing the point-slope form in the slope-intercept form

[tex]y-4=-4\left(x+1\right)[/tex]

add 4 to both sides

[tex]y-4+4=-4\left(x+1\right)+4[/tex]

[tex]y=-4x[/tex]

Answer:

D: x=12

Step-by-step explanation:

Answer:

x = 53

y = 30

Step-by-step explanation:

Step(I):-

Given equations are

x -2y =-7 ...(I)

5x-9y =-5 ..(ii)

The matrix form  AX = B

                    [tex]\left[\begin{array}{ccc}1&-2\\ 5 & -9\\\end{array}\right] \left[\begin{array}{ccc}x\\y\\\end{array}\right] = \left[\begin{array}{ccc}-7\\-5\\\end{array}\right][/tex]

The determinant

[tex]= \left|\begin{array}{ccc}1&-2\\5&-9\\\end{array}\right| = -9+10 =1[/tex]

By using Cramer's Rule

Δ₁ =      [tex]\left[\begin{array}{ccc}-7&-2\\\\-5&-9\end{array}\right][/tex]



The determinant is     Δ₁ = -9 X -7 - (10 ) = 53

x = Δ₁ / Δ

x = 53

The determinant

Δ₂ =



Δ₂ = -5 +35

     

y = Δ₂/Δ =  30

 x - 2y = -7

5x - 9y = -5​

[tex]D=\left|\, 1\quad-2\atop5\quad-9\right|=1\cdot(-9)-(-2)\cdot5=-9+10=1\\\\\\x=\dfrac{\left|-7\quad-2\atop-5\quad-9\right|}1=-7(-9)-(-2)(-5)=63-10=53\\\\\\y=\dfrac{\left|\, 1\quad-7\atop5\quad-5\right|}1=1\cdot(-5)-(-7)\cdot5=-5+35=30[/tex]
