C) 1000. 10 raised to the 3rd power would mean you multiply 10 by itself 3 times, and 10*10*10 is 1000 :p

Answer:

4x + 10 > 3x + 14

x > 4

Step-by-step explanation:

Use the given values for length and width in the formula for perimeter of a rectangle. You will be able to find the perimeter of rectangles A and B.

A = 2(l + w)

A = 2(x + 5 + x)

A = 2(2x + 5)

A = 4x + 10

B = 2(l + w)

B = 2(x + 7 + x/2)

B = 2(3x/2 + 7)

B = 3x + 14

The perimeter of rectangle A is larger than that of rectangle B.

A > B

4x + 10 > 3x + 14

(4x + 10) - 3x > (3x + 14) - 3x

x + 10 > 14

(x + 10) - 10 > 14 - 10

x > 4

Which statement about this product is true? 0.36×(-7 5/8)

Schach [20]

A.It is less than -7 5/8
because multiplying by a number less than 1
gives a smaller number.
B.It is greater than -4
because 0.36×(7 5/8)
0.36*(7 5/8) is less than 1/2 * 8
C.It equals -7 5/8
because 36/36
equals 1
, and 1
times any number equals that number.
D.It equals 0
because 0.36
rounded to the nearest whole number is 0
, and 0
times any number is 0.
THESE ARE ALL THE ANSWER CHOICES!!!

After t years, the remaining mass y (in grams) of an initial mass of 35 grams of a radioactive element whose half- life is 80 ye

IgorC [24]

Answer: There will be 22.694 grams of initial mass remains after 50 years.

Step-by-step explanation:

Since we have given that

$y=35(\dfrac{1}{2})^{\frac{t}{80}$

We need to find the quantity of initial mass remains after 50 years.

So, t = 50 years,

We get that

$y=35(\dfrac{1}{2})^{\frac{50}{80}}\\\\y=35(0.5)^{0.625}\\\\y=22.694$

Hence, there will be 22.694 grams of initial mass remains after 50 years.

First find midpoint: $\left( \frac{-1+5}{2}, \frac{6+5}{2}\right) = (2, 5.5)$

Find slope of line that passes through R and S: slope = $\frac{6-5}{-1-5} = \frac{-1}{6}$

Negative reciprocal of slope to get slope of perpendicular: new slope = 6

Line will be: $y-5.5=6(x-2)$

$y = 6x - 6.5$
