Which number line represents the solution of 1 - 2x ≥ 3

Andrew [12]

Answer:

Step-by-step explanation:

First subtract the 1 from both sides. this leaves you with a -2x on one side and a 2 on the other side. Divide the -2, and remember that when you divide a negative number, the sign in the middle flips meaning that the answer would be x is less than or equal to -1.

Suppose you work for a sporting goods company, and you want to order shipping boxes for bike helmets. Each helmet is already pac

madreJ [45]

Answer: $n^2+6n-135=0$

Step-by-step explanation:

The length, width and height of the smaller box are n inches , n inches and 8 inches respectively,

And, According to the question,

The shipping boxes has 2 inches extra width than that of smaller box and 4 inches extra length than that of smaller box, Also, The height of the shipping box should be the same as the helmet box.

Thus, the Length of the shipping box = (n + 4) inches

Width = (n+2) inches and height = 8 inches

Thus, the volume of the shipping box,

$V = (n+4)\times (n+2)\times 8=(n^2+6n+8)8=8n^2+48n+64$

But, V = 1,144 cubic inches,

⇒ $8n^2+48n+64=1144$

⇒ $n^2+6n+8=143$

⇒ $n^2+6n-135=0$

Which is the required equation that models the volume of the shipping box.

Ms. Emily buys a hat and gloves with a coupon for 30% off her entire purchase. The gloves cost $35 before the discount. Her bill

Gennadij [26K]

$44.80=($35+X)(1-0.3)

44.80 is the final total
You need to add the glove and hat cost to get a subtotal (35+x) and then multiply by what is left after the discount 30% off will leave 70% to pay, so in this equation 1-0.3 leaves 0.7 to multiply against the subtotal to get the total before tax of 44.80

1. ABCD is a square with side length 12 cm.

AnnyKZ [126]

Answer:

Exact Area of shaded region = 141.39cm²

Step-by-step explanation:

Quadrant of a circle - Quadrant refers to the four quarters in the coordinate plane system. Each of the four sections is called a quadrant. When it comes to circle, the quarter of a circle is called a quadrant, which is a sector of 90°.

area of circle =πr²

area of quadrant of a circle = πr²/4

where r is the radius of the circle.

In the given figure there are 2 types of quadrants of circle are present

one with radius AB (bigger )

another with radius AB/2 (smaller)

Now area of quadrant having radius = AB

⇒ π(AB) ²/4

here AB is the side of square

so AB = 12cm

substituting this in the area of quadrant formula

area of bigger quadrant = π(12²)/4

area₁ = 144×π/4

area₁ = 144×3.142/4

area₁ = 113.112cm²

now area of smaller quadrant = π(AB/2) ²/4

area ₂ = π(6) ²/4

area ₂ = 36π/4

area ₂ = 9×π

area ₂ = 28.278cm²

Now it is clear from the given figure,

area of shaded region is = area₁ - area₂ +2×area₂

= 113.112cm² - 28.278cm² + 2× 28.278cm²

= 113.112cm² + 28.278cm²

= 141.39cm² (answer)
