A mathematics book has 360 pages, of which 50% are on algebra, 20% on geometry and the remainder on arithmetic how many pages ar

Arte-miy333 [17]

Answer:

30% of the pages are arithmetic, or 108 pages

Step-by-step explanation:

50% are on algebra = 180 pages

360 x .5 = 180

20% are on geometry = 72 pages

360 x .2 = 72

30% are on arithmetic = 108

180 + 72 + 108 = 360 pages

50% + 20% + 30% = 100%

I need help with the steps. The answer is (5,2)

Elden [556K]

So with this, I will be using the substitution method. With the first equation, substitute (y+3) into the x variable and solve for y:

$y+3+y=7\\2y+3=7\\2y=4\\y=2$

Next, now that we have the value of y, substitute it into either equation to solve for x:

$x+2=7\\x=5\\\\x=2+3\\x=5$

<u>And this is how you get your final answer (5,2).</u>

A tub of water drains at 3 gallons per minute. y-12=-3(x-1)

Natali [406]

If you plot 3,12 on a graph and go move to the
left one and up one untill the x axis is zero you
will land on five. so the amount the tub started
with is 15

Which values of x would make a polynomial equal to zero if the factors of the polynomial were (x-2) and (x-11)?

Mama L [17]

<span>if the factors of the polynomial were (x-2) and (x-11), then if anyone of them is equal "0", a polynomial will be equal zero.
x-2=0
x=2
x-11=0
x=11

A polynomial will be equal 0 if x=2, or x=11.</span>

Find the value of x in the isosceles triangle shown below.

guajiro [1.7K]

Answer:

B) $x = \sqrt{60}$

Step-by-step explanation:

1. As you can see from the image, there are two right triangles in the isosceles triangle. The base of each right triangle is 2 (because 4 ÷ 2 = 2), and the hypotenuse is 8.

2. Let's use Pythagorean Theorem to find the height of each right triangle, which will also give us the height of the isosceles triangle: $a^2 + b^2 = c^2$ , where a = height, b = base, and c= hypotenuse.

$a^2 + 2^2 = 8^2$
$a^2 + (2*2) = (8*8)$
$a^2 + 4 = 64$ (Simplify both sides of the equation)
$a^2 + 4 - 4 = 64 - 4$ (Subtract 4 from both sides)
$a^2 = 60$
$\sqrt{a^2} = \sqrt{60}$ (Take square root of both sides
$a = \sqrt{60}$

3. The√(60) is the height of each right triangle, and it's also the height of the isosceles triangle. Therefore, the answer is B) x = √60.
