15/40 is a terminating decimal

ollegr [7]3 years ago

4 0

Answer:

See below

Step-by-step explanation:

If the denominator of a fraction has only factors of 2 and 5, the decimal expression terminates.

If the denominator contains a factor other than 2 or 5, then the decimal expression repeats.

56/72 is a repeating decimal

72 contains a factor of 9.

12/30 is a terminating decimal.

30 contains factors of 2 and 5

15/40 is a terminating decimal.

40 contains factors of 2 and 5

12/37 is a repeating decimal.

37 does not contain factors of 2 or 5.

Find the volume of the pyramid below.

olganol [36]

Answer:

Option B. $192\ units^{3}$

Step-by-step explanation:

we know that

The volume of the square pyramid is equal to

$V=\frac{1}{3}b^{2}H$

where

b is the length side of the square base

H is the height of the pyramid

we have

$b=8\ units$

$H=9\ units$

substitute

$V=\frac{1}{3}(8)^{2}(9)$

$V=192\ units^{3}$

Y equals equation for the line that passes through the points (-6,2) and (1,16)

8_murik_8 [283]

Slope-intercept form: y = mx + b

[m is the slope, b is the y-intercept or the y value when x = 0 ---> (0, y) or the point where the line crosses through the y-axis]

To find the slope, you use the slope formula:

$m=\frac{y_2-y_1}{x_2-x_1}$ And plug in the two points

(-6, 2) = (x₁ , y₁)

(1, 16) = (x₂ , y₂)

$m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{16-2}{1-(-6)}$ [two negatives cancel each other out and become positive]

$m=\frac{16-2}{1+6}$

$m=\frac{14}{7}$

m = 2 Now that you found m, plug it into the equation

y = mx + b

y = 2x + b To find b, plug in one of the points into the equation

(-6, 2)

y = 2x + b

2 = 2(-6) + b

2 = -12 + b Add 12 on both sides

14 = b

(1, 16)

y = 2x + b

16 = 2(1) + b Subtract 2 on both sides

14 = b

Now that you found b, plug it into the equation

y = 2x + 14

One positive integer is 6 less than twice another. The sum of their squares is 801. Find the integers

xxTIMURxx [149]

Answer:

$\large \boxed{\sf 15 \ \ and \ \ 24 \ \ }$

Step-by-step explanation:

Hello,

We can write the following, x being the second number.

$(2x-6)^2+x^2=801\\\\6^2-2\cdot 6 \cdot 2x + (2x)^2+x^2=801\\\\36-24x+4x^2+x^2=801\\\\5x^2-24x+36-801=0\\\\5x^2-24x-765=0\\\\$

Let's use the discriminant.

$\Delta=b^4-4ac=24^2+4*5*765=15876=126^2$

There are two solutions and the positive one is

$\dfrac{-b+\sqrt{b^2-4ac}}{2a}=\dfrac{24+126}{10}=\dfrac{150}{10}=15$

So the solutions are 15 and 15*2-6 = 30-6 = 24

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
