Step-by-step explanation:

(5 × 2 + 14x - 15) - (3 × 2 + 5 + 7)
(10 + 14x - 15) - (3 × 2 + 5x + 7)
(10+14x-15) - (6 + 5x+7)
(- 5+14x) - (6+5x+7)
(-5+14x)-(13+5x)
- 5+14x (13+ 5x)
- 5 + 14x - 13 - 5x
- 18+14x - 5x

Answer:- 18 + 9x

Number 17 please and thank you . I don’t understand it . Do you plug in each 10-50 as T into your calculator?

Nat2105 [25]

The half-life for such a substance is the time $t$ required to have the amount (in grams $\mathrm g$ ) at time $t$ (in seconds $\mathrm s$ ), $y(t)$ , decay to half the starting amount $y_0$ . In other words, for krypton-91, after 10 seconds we would have $y(10\,\mathrm s)=\dfrac{y_0}2$ . We can use this information to solve for $k$ , then plug in various values of $t$ to find the amount of krypton-91 that's left...

But we don't need to! We already know it takes 10 seconds for half of the substance to decay. So if we start with 16 grams, then after 10 seconds, 8 grams will remain.

10s later (after a total of 20 seconds), 4g will remain.

10s later (30s), 2g will remain.

10s later (40s), 1g will remain.

10s later (50s), 1/2 g will remain.

A directed line segment on a gridded map shows the path of a hot air balloon from 1(0,0) to B(8,4). Each grid unit represents 1

aivan3 [116]

Answer:

Step-by-step explanation:

There is a point V with ration 6 to 2, therefore we must find the coordinates of point V and the distance from A to V

According to the graph

$c^{2}=x^{2}+y^{2}\\c^{2}=8^{2}+4^{2}\\c=\sqrt{64+16}=8.9.4\\sin\alpha =\frac{4}{8.94}$

α≅27°

V=2*8.94/6 (ratio 6:2)

V=2.98mile

$sin27=\frac{y}{2.98}\\y=sin27*2.98=1.35\\cos27=\frac{x}{2.98}\\x=cos27*2.98=2.65$

coordinates of V = (2,65;1.35)

Distance from A to V

$d_{AV}=2.98 miles$

finally

Mary's mistake is to take the 6 to 2 ratio as the distance traveled from the globe only in the x direction

hettie is stacking paper cups .each stack of 15 cups is 6 inches high. what is the total heightvof 10 stacks of cups ?

Maslowich

60 inches is the answer.

In this case the amount of cups do not matter only the height because that's what it's asking for.

If each stack is 6 inches we would have to multiply that by 10 because there are 10 stacks.

6 x 10 = 60 inches tall

Alex is 12 years older than George. Carl is Three times older than Alex The sum of their ages is 68 Find the ratio of George’s a

earnstyle [38]

Ratio of George’s age to Carl’s age to Alex’s age is 1 : 12 : 4

Solution:

Let "a" be the age of Alex

Let "g" be the age of George

Let "c" be the age of Carl

Alex is 12 years older than George

Therefore,

Age of Alex = 12 + Age of George

a = 12 + g

g = a - 12 ---- eqn 1

Carl is Three times older than Alex

Age of Carl = 3 x Age of Alex

c = 3a -------- eqn 2

The sum of their ages is 68

age of Alex + age of George + age of Carl = 68

a + g + c = 68 ----------- eqn 3

Substitute eqn 1 and eqn 2 in eqn 3

a + a - 12 + 3a = 68

5a - 12 = 68

5a = 12 + 68

5a = 80

a = 16

Substitute a = 16 in eqn 2

c = 3(16) = 48

c = 48

Substitute a = 16 in eqn 1

g = 16 - 12 = 4

g = 4

Find the ratio of George’s age to Carl’s age to Alex’s age

Ratio of George’s age to Carl’s age to Alex’s age = g : c : a

g : c : a = 4 : 48 : 16

Divide the above ratio by 4 to reduce to lowest terms

g : c : a - 1 : 12 : 4

Thus ratio of George’s age to Carl’s age to Alex’s age is 1 : 12 : 4

Samuel took an antique clock that his grandfather had purchased, to be appraised. The appraiser evaluated the current price of t

andrew11 [14]

This is an exponential growth problem. Exponential growth can be expressed mathematically in the following way:
$y=a (1+r)^{t}$ .
Parameter a presents initial amount.
Parameter r is percentage increase.
Parameter t is time.
An equation that would describe given problem is:
$y=400 (1+0.02)^{t}$
t is the time in years.
I attached the graph of this function.
