Answer:

The housewife purchased 8 chairs

since the selling price is 89.83 and the cost of is 76, the tax amount is 89.83 - 76 = 13.83.

if we take 76 to be the 100%, what is 13.83 off of it in percentage?

[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} 76 & 100\\ 13.83& x \end{array} \implies \cfrac{76}{13.83}=\cfrac{100}{x} \\\\\\ 76x=1383\implies x=\cfrac{1383}{76}\implies x\approx 18.20[/tex]

Answer:

[tex]\sf y=3x+2[/tex]

Step-by-step explanation:

Point-slope form of linear equation:  [tex]\sf y-y_1=m(x-x_1)[/tex]

(where m is the slope and (x₁, y₁) is a point on the line)

Given:

Substituting given values into the equation to find the equation of the line:

[tex]\implies \sf y-17=3(x-5)[/tex]

[tex]\implies \sf y-17=3x-15[/tex]

[tex]\implies \sf y=3x+2[/tex]

Answer:

57/40

Step-by-step explanation:

So we need to find the LCD, or the least common denominator.  The LCD is 40.  Now, we do a transition to find the new numerator.

[tex]\frac{4}{5} =\frac{x}{40} \\\\\\frac{5}{8} = \frac{x}{40}[/tex]

The new equation is this:

[tex]\frac{32}{40} +\frac{25}{40}[/tex]

Now we use our common sense.  32+25=57

57/40.

Answer:

  (d)  112 m²

Step-by-step explanation:

The area of a parallelogram is given by the formla ...

  A = bh . . . . . . where b is the base length and h is the height

__

Here, the base is divided into parts, but their total length is 5m+9m = 14m. The height is given as 8m, so the area is ...

  A = (14 m)(8 m) = 112 m²

The area of the parallelogram is 112 square meters.

__

Alternate solution

You can also figure this as the sum of the areas of the two triangles and that of the center rectangle.

  A = 2(1/2bh) +bh

  A = 2(1/2(5 m)(8 m)) +(9 m)(8 m) = 40 m² +72 m² = 112 m²

Answer:

No

Step-by-step explanation:

Tyler is incorrect. The only way you can set individual terms equal to the result is when the result is zero. This is due to zero times anything equalling zero. If one of the terms equals zero, then the other term does not matter because the whole thing will be zero. Let's say:

[tex](2 - x)(x + 1) = 0[/tex]

If the first term equals zero, the entire left side is zero. For Priya's case, the right side is not zero, it is 11. If one term is 11, the other term will contribute. You can check this by plugging in Tyler's solutions. The correct way to solve this equation is to use FOIL on the two terms, then subtract 11 on both sides to get zero. Then use the quadratic formula.

Answer:

It will land 7.5 times on tails, which is rounded up to 8 times

Step-by-step explanation:

there are 2 possibilities, heads or tails

so you divide 15 in 2 and get 7.5

The coin will land 7 times tail based on the experimental probability.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

When the coin tossed 45 times.

Head= 24, tail = 21

So, fraction of appearing tail will be

= 21 / 45

= 0.466667

Now, if the coin tossed 15 times then the coin land on tails

= 15 x 0.466667

= 7

Answer: 35

Step-by-step explanation: The reason is that 7 × 5 = 35 and when you multiply two negative numbers they make the answer positive. I hope this helped!

Answer:

35

Step-by-step explanation:

7 times 5 equals 35. Even though the two numbers are positive, the product will be negative, because a negative times a negative equals a positive. A negative times a negative will equal a positive because what was originally negative has been reversed in direction.

So, the answer is 35.

I'm assuming the question is how many miles in total did mary swim.

if this is the case then we just multiply the number of days by the number of miles per day.

Hence,

Answer:

[tex]x + y = -2\\x-y=8[/tex]

Step-by-step explanation:

3 is the [tex]x[/tex], and -5 is the [tex]y[/tex].

1) Create two equations that add and subtract them.

[tex]x + y = -2\\x-y=8[/tex]

2) Check whether you get the same answer (3,-5) or not. To do so, you need to solve them simultaneously using the elimination or substitution method. I will demonstrate using the substitution method.

[tex]x = -2 - y\\x-y=8\\(-2 - y) -y =8\\-2-2y=8\\-2y = 8 + 2\\-2y = 10\\y = \frac{10}{-2} \\y = -5[/tex]

To find [tex]x[/tex], substitute the result into one of the two equations. I choose [tex]x+y=-2[/tex].

[tex]x-5=-2\\x = -2 +5\\x = 3[/tex]
