Translate the following phrase into an inequality:

1 answer:

Answer:

The term "at least" means the lowest number you can have. In other words, you cannot have a number less than that point. So we use the greater than or equal symbol.

x - 3 ≥ - 5

Add 3 on both sides of the inequality.

x ≥ -2

x is any number greater than or equal to -2.

If the term was "at most", then that is the highest number you can have, and you can go no higher than that. In this case, we would have used the less than or equal to symbol.

These terms are important to understand when working with inequalities.

1. Marcus bought a $40.00 tennis racket. He has a coupon for 20% off. The Sales tax where he bought the tennis racket is 6%. a.

jeka94

Answer:

$33.92

Step-by-step explanation:

First, we have to find how much the sale price for the tennis racket is before tax.

100% - 20% = 80% Marcus has to pay 80% of the original price.

80% * 40 = .8 * 40 = 32

Marcus has to pay $32 for the tennis racket before tax.

6% = .06 (tax percentage)

.06 * 32 = 1.92 ————> tax

Add the tax with the sale price.

32 + 1.92 = 33.92

Marcus has to pay $33.92 for the tennis racket.

If someone can answer all these ill give 100 points

Helga [31]

Answer:

1. x = -6

2. x = 2

3. x = 6

4. x = 3

5. x = -5

6. x = -1

7. x = 0

8. x = 9

9. x = -4

10. x = 7

Step-by-step explanation:

1.

$-10x = -8x + 12$

$-10x+8x=-8x+12+8x$
$-2x=12$

$-2x/-2=12/-2$
$x=-6$

2.

$9-5x+x=1-x+x$
$-4x+9=1$

$-4x+9-9=1-9$
$-4x=-8$

$-4x/-4=-8/-4$
$x=2$

3.

$-2x+16-x=x-2-x$
$-3x+16=-2$

$-3x+16-16=-2-16$
$-3x=-18$

$-3x/3=-18/-3$
$x = 6$

4.

$(-4)(6x)+(-4)(-2)= -8x-40$
$-24x+8=-8x-40$

$-24x+8+8x=-8x-40$
$-16x+8=-40$

$-16x+8-8=-40-8$
$-16x=-48$
$-16x/-16=-48/-16$
$x=3$

5.

$37 - 8x = (-7)(x)+(-7)(-6)$
$-8x+37=-7x+42$
$-8x + 37 + 7x = -7x + 42 + 7x$
$-x+37=42$
$-x+37-37=42-37$
$-x=5$
$-x/-1=5/-1$
$x=-5$

6.

$6x+(-2)(2)+(-2)(8x) = 10 + 4x$
$6x-4-16x = 10 + 4x$
$-10x - 4 = 4x + 10$
$-10x - 4 -4x=4x+10-4x$
$-14x-4=10$
$-14x-4+4=10+4$
$-14x=14$
$-14x/-14=14/-14$
$x=-1$

7.

$(-2)(x) + (-2)(1) = (2)(x) + (2)(-1)$
$-2x-2=2x-2$
$-2x-2-2x = 2x - 2 - 2x$
$-4x - 2 = -2$
$-4x-2+2=-2+2$
$-4x=0$
$-4x/-4=0/-4$
$x=0$

8.

$(-3)(x)+(-3)(3)=(-6)(x)+(-6)(-3)$
$-3x-9=-6x+18$
$-3x-9+6x=-6x+18+6x$
$3x-9=18$
$3x-9+9=18+9$
$3x=27$
$3x/3 = 27/3$
$x=9$

9.

$6x-36=(-4)(-2x)+(-4)(7)$
$6x-36= 8x -28$
$6x-36-8x = 8x - 28 - 8x$
$-2x-36=-28$
$-2x-36+36=-28+36$
$-2x = 8$
$-2x/-2=8/-2$
$x=-4$

10.

$(2)(x)+(2)(1) = -2x + 30$
$2x+2=-2x+30$
$2x+2+2x=-2x+30+2x$
$4x+2=30$
$4x+2-2=30-2$
$4x=28$
$4x/4=28/4$
$x=7$

The canopy of a parachute is a semicircle with a radius of 13 feet. A company that is making parachutes for a Fourth of July cel

Mars2501 [29]

ANSWER

(2). 88.5 ft²

EXPLANATION

The parachute is in the form of a semicircle, so the area of the entire parachute can be calculated using the formula,

Area=½ πr²

The radius is 13cm.

We substitute the radius to get

$Area= \frac{1}{2} \pi \times {13}^{2}$

$= 265.46457922834 \: \: {ft}^{2}$

The company required that, each parachute be made from equal parts of red, white, and blue fabric.

Hence, the fabric of each color needed is

$= \frac{265.46457922834}{3} = 88.4882$

To the nearest tenth, we have,

$= 88.5 {ft}^{2}$
