If a $1000 computer is marked off 35%, what is the sale price?

A) $300

B) $350

C) $650

D) $1350

Use a similar strategy as in your other question, [19925664].

3x² + 4x + 12 = 3 (x - r ) (x - s)

3x² + 4x + 12 = 3 (x² - (r + s) x + rs)

3x² + 4x + 12 = 3x² - 3 (r + s) x + 3rs

so that

r + s = -4/3

rs = 12/3 = 4

Recall that

(r + s)² = r² + 2rs + s²

so that

r² + s² = -2rs = -2(4) = -8

Answer: 24 band posters should be sold

Step-by-step explanation:

First take the expression down to its simplest form;

= 5:4

Assume she sells 30 movie posters, her movies posters drop to;

= 100 - 30

= 70 movie posters

We need a number of band posters remaining that will give a ratio of 5:4 with movie posters.

In fraction form, the number of movie posters is;

= 5/9 because 9 would be the total number of both movie posters and band posters.

Create an expression to find the total number of posters if 70 are movie posters;

5/9x = 70

x = 70 ÷ 5/9

x = 126 posters

Number of band posters that should be left are;

= 126 - 70

= 56

Number of band posters that should be sold;

= 80 - 56

= 24 posters

The new ratio would be 70:56.

Answer:

All options have possible values of an integer

Explanation:

From the above options given all options are integers. An integer is a whole number, that is a number that is not a fraction or a decimal number. An integer can be negative, positive or zero such as the above given numbers. Here there are no fractions such as 1/4 or improper fractions as 1 3/4 or decimal numbers as 2.543, therefore all options are correct.

Answer:

Step-by-step explanation:

The area formula for a square is

[tex]A=s^2[/tex] where A is the area and s is a side measure. In a square, this side measure is the same (because all 4 sides in a square are the same). Therefore, our formula becomes:

[tex]1369=s^2[/tex]

Take the square root of both sides to find that a side measures 37 m.

The perimeter of a square is to add all 4 sides together (or to multiply the one side by 4):

4 * 37 = 148 m

Answer:

[tex]18 + 24 = 6 * 7[/tex]

Step-by-step explanation:

Given

Required

Write as a product

Start by expanding the expression with a common factor

[tex]6 * 3 + 6 * 4[/tex]

Factorize:

[tex]6 ( 3 + 4)[/tex]

Express 3 + 4 as 7

[tex]6 (7)[/tex]

Convert () to multiplication

[tex]6 * 7[/tex]

Hence:

[tex]18 + 24 = 6 * 7[/tex]

Answer: 51 notes span 6 octaves.

Step-by-step explanation:

The word "octave" is a Latin word that means "eight".

In an instrument, Each octave is made up of 8 musical notes.

If we have 51 notes , the number of octaves can be made in it = [tex]\dfrac{51}{8}[/tex]

[tex]=6.375\approx6\ \ \ \ \ \text{[Rounded to the nearest whole number]}[/tex]

Hence, 51 notes span 6 octaves.

Answer:

14.9 miles

Step-by-step explanation:

In the image below, the side of the triangle a, represents; "Peter leaves work and drives 10miles due south".

The side of the triangle b represents; "he then heads east for 11 miles to reach his home"

The distance between his work and home is represented by side c of the triangle.

This is a tight angle triangle, hence pythagoras theorem would be applied in solving it.

This theorem states that the square of the hypotenuse of a right angle triangle is equal to the sum of the squares of the other two sides;

This means we have;

c² = a² + b²

c² = 10² + 11²

c = √(100+121)

c = 14.87

Rounding off to the nearest tenths = 14.9

Step-by-step explanation:

The approximate tip is - 12.30$

Because bill is 81.79$

and tip - 15%

therefore bill amount divided by 15/100

==> 81.79* 15% is 12.30$

Answer:

  18

Step-by-step explanation:

There are two areas where the circles P and C overlap. One is labeled "4" and the other is labeled "3x". The sum of these two values is the number of people who like Pop and Classical  music, 13.

  4 + 3x = 13

  3x = 9 . . . . . subtract 4

  x = 3 . . . . . . divide by 3

__

We are asked to find the number of people who like two types only. The three regions where only two circles overlap are labeled x, 3x, and 6. The answer to the question is the sum of these values.

  like 2 types only: x +3x +6 = 4x +6 = 4(3) +6 = 18

18 students like two types of music only.

Its the first answer because 7 divided by 1 = 7, 14 divided 2= 7, 28 divded 4 = 7

Answer:

∠ 6 = 28°

Step-by-step explanation:

152° and ∠ 5 are corresponding angles and are congruent, then

∠ = 152°

∠ 5 and ∠ 6 are adjacent angles and are supplementary, thus

∠ 6 = 180° - 152° = 28°

Answer:

2.25

Step-by-step explanation:

1.5 times 1.5 is 2.25

"simplify" just means to solve in ur case..

Hope this helps!!

1.5 multiplied by 1.5 equals 2.25.

To simplify the problem 1.5 x 1.5, you can multiply the two numbers together.

To calculate this, you can follow these steps:

Multiply the first digit of the first number (1) by the first digit of the second number (also 1): 1 x 1 = 1.

Multiply the decimal parts of both numbers: 0.5 x 0.5 = 0.25.

Add the results from step 1 and step 2 together: 1 + 0.25 = 1.25.

The final answer is 1.25, but we need to consider the decimal places. Since both numbers have one decimal place, the final answer will have two decimal places: 2.25.

Therefore, 1.5 x 1.5 simplifies to 2.25.

thos was super hard to do

Step-by-step explanation:

Answer:

slope=1

y-intercept=10

linear equation is y =x+10

Step-by-step explanation: to find slope take 2 points (0,10) and (2,12) as (x1,y1) and (x2,y2) respectively. Using slope formula(y2-y1/x2-x1) we get (12-10)/(2-0) which simplifies to 2/2 which is 1. y-intercept is the point where x is 0, then y is a number called y-intercept. And in the table when x=0 ,y=10 therefore 10nis the y-intercept. As for the linear equation, y=mx+b it simply is y=slope×x +y-intercept, from the previous question we can say y=1x+10 ( in math its better if the coefficient of x is 1 we can just say x) which is y=x+10.

Answer:

x=2<br/>y=1

Step-by-step explanation:

\left\{ \begin{array} { l } { 4 x + y = 9 } \\ { 3 x - 2 y = 4 } \end{array} \right.

4x+y=9,3x-2y=4

4x+y=9

4x=-y+9

x=\frac{1}{4}\left(-y+9\right)

x=-\frac{1}{4}y+\frac{9}{4}

3\left(-\frac{1}{4}y+\frac{9}{4}\right)-2y=4

-\frac{3}{4}y+\frac{27}{4}-2y=4

-\frac{11}{4}y+\frac{27}{4}=4

-\frac{11}{4}y=-\frac{11}{4}

y=1

x=\frac{-1+9}{4}
