Answer:

7 is the answer

Explanation:

because if you use a calculator, by doing 10% of 70 which equals to 7 which that is the answer.

Answer:

B: $63

Step-by-step explanation:

You can make an equation: 70(10%)

    Which can be simplified into 70(0.1)

70×0.1=7

Since it was discounted, you subtract

$70 - $7 = $63

Answer:

460 pounds.

Step-by-step explanation:

5% of 2,300 is 115. Since it is in there for four years, you multiply 115 by 4 to get 460.

Answer:

A = 8,160 ft²

Step-by-step explanation:

A = 1/2h(sum of bases)

h = 102

bases = 75 and 85

A = 1/2(102)(75+85)

= 51(160)

= 8,160 ft²

Answer: x=120

Step-by-step explanation:

(2x-50)+(x+40)+150+80+(x+20)+90= 720

4x+330= 720

4x=390

x=97.5

Answer:

One of the limitations of using the range is that it is a simple but poor measure of variability. It is very susceptible to poor representation of data spread.  It is used mostly with ordered data or ordinal data.                                          

Step-by-step explanation:

The measure of the range of a set of given data can be established once the difference between the highest and lowest values is known.

The range is simple to use but only considers the smallest and largest data elements in the set without considering the middle values and other values that could influence results if the data spread is to be considered.

Ordinal data aren't numerical data. Examples include Time of day such as morning, noon, night.

Answer:

Irrational, because it's a decimal that repeats

Answer:

The original length is 9 cm and the original width 5 cm

Step-by-step explanation:

The area of  a rectangle A is given as the product of its' length L and width W.

Given that the width of a rectangle is 4cm less than the length then

W = L - 4

If each dimension were increased by 3cm, then the new

Length

= L + 3

Width

= W + 3

the width of the new rectangle formed would be 2/3 the length of the new rectangle

W + 3 = 2/3(L + 3)

3W + 9 = 2L + 6

3W = 2L +6 - 9

3W = 2L - 3

Recall that W = L - 4

3(L - 4) = 2L - 3

3L - 12 = 2L - 3

3L - 2L = 12 - 3

L = 9 cm

W = 9 - 4

= 5 cm

Answer:

Step-by-step explanation:

Answer:

y = 4/3 x + 4

Step-by-step explanation:

The general form of the equation of a line is given as

y = mx + c where m is the slope and c is the intercept on the y axis

where the slope m = (y2 - y1)/(x2 - x1)

Hence given the points  (-6, -4) and (0, 4)

m = (4 --4) / (0 --6)

= (4+4)/(0+6)

= 8/6

= 4/3

For a line with given points (x1, y1), the equation is given as

y-y1 = m(x-x1)

Hence the equation of this line in slope-intercept form

y - -4 = 4/3(x --6)

y + 4 = 4/3(x + 6)

3y + 12 = 4x + 24

3y = 4x + 24 - 12

3y = 4x + 12

y = 4/3 x + 4

For a line with given points (x2, y2), the equation is given as

y-y2 = m(x-x2)

Hence the equation of this line in slope-intercept form

y-4 = 4/3(x - 0)

multiply through by 3

3y - 12 = 4x

3y = 4x + 12

y = 4/3 x + 4

Answer:

A

Step-by-step explanation:

Answer:

-1 and 4/3

Step-by-step explanation:

Given the quadratic equation;

f(x) = 3x^2-x-4

To get all potential roots, we will equate f(x) = 0

3x^2-x-4 = 0

3x^2-4x+3x-4 = 0

x(3x-4)+1(3x-4) = 0

(x+1)(3x-4) = 0

x+1= 0 and 3x-4 = 0

x = -1 and 3x = 4

x = -1 and x= 4/3

Hence the potential roots are -1 and 4/3

Answer:

113 square feet

Step-by-step explanation:

Given

[tex]d = 24[/tex] --- diameter

See attachment for complete question

Required

Determine the area of each color

First, we calculate the area of all colors

[tex]Area = \frac{\pi d^2}{4}[/tex]

This gives:

[tex]Area = \frac{22 * 24^2}{7*4}[/tex]

[tex]Area = \frac{12672}{28}[/tex]

[tex]Area = 452.57[/tex]

Since all 4 colors have equal areas, the area of 1 of them is:

[tex]A = \frac{1}{4}Area[/tex]

[tex]A = \frac{1}{4} * 452.57[/tex]

[tex]A = 113.14ft^2[/tex]

[tex]A = 113ft^2[/tex] --- approximated

Answer:

let the no. of students in art class be x

then

9+4x=101

now u can solve it! u will get x = 23

To solve system of equations by substitution, we are going to use the first equation to substitute into the second equation wherever you see y.

[tex]5x - 4y = -3[/tex]

[tex]5x - 4(3x-5) = -3[/tex]

[tex]5x -12x+20=-3[/tex]

               [tex]-20[/tex]     [tex]-20[/tex]  

_______________

[tex]5x-12x=-23[/tex]

[tex]-7x=-23[/tex]

___    ____

 [tex]-7[/tex]       [tex]-7[/tex]

[tex]x=3.29[/tex] (rounded)

Next, substitute x = 3.29 into the first equation, or to any equation you'd like, to find y.

[tex]y = 3x-5[/tex]

[tex]y = 3(3.29)-5[/tex]

[tex]y = 9.87-5[/tex]

[tex]y = 4.87[/tex]

So, your final answer would be (3.29, 4.87).
