Answer:
50%
Step-by-step explanation:
Let [tex]x[/tex] be equal to the decimal when multiplied by 2 equals 1
[tex]2x=1[/tex]
Divide both sides by 2
[tex]\frac{2x}{2} =\frac{1}{2} \\x=0.5[/tex]
Multiply the decimal by 100 to get a percent
0.5×100=50%
I hope this helps!
Help please! would appreciate it

yes
Step-by-step explanation:
just plug in
2+3 is equal to 5 so that works
4(2)+13(3) is greater than 20 so that also works
Answer:
Yes
Step-by-step explanation:
I can explain more in-depth if you'd like, but basically plug in 2 where x is and plug in 3 where y is. The first equation would turn into 2 + 3 ≤ 5, which is correct, and the second equation would transform to 4(2) + 13(3) > 20. Multiply, then it'll be 8 + 39 > 20, then add 8 and 39 and it'll be 47 > 20, which is true. I hope I explained that well, but yes, (2, 3) is a solution :)

What is the value of the expressions below when n = 1.5?
5n – (20 + n)
Answer:
-14
Step-by-step explanation:
if n = 1.5, replace all letters labeled "n" with 1.5
5(1.5) - (20 +1.5)
5 x 1.5 = 7.5
(20+1.5) = 21.5
7.5 - 21.5 = -14

Answer:
answer is -14

Solve systems using Elimination
Answer:
y = 1.5, x = [tex]1\frac{12}{13}[/tex]
Step-by-step explanation:
The given simultaneous equation system is;
-1 - 2·y = -4...(1)
13·x + 2·y = 28...(2)
By elimination method, we have;
From equation (1);
-1 - 2·y = -4
2·y = 4 - 1 = 3
y = 3/2 = 1.5
y = 1.5
We eliminate 'y' from equation (2) by replacing the value of 'y' with 1.5 as follows;
13·x + 2·y = 28
y = 1.5
∴ 13·x + 2 × 1.5 = 28
13·x = 28 - 3 = 25
x = 25/13 = [tex]1\frac{12}{13}[/tex] = [tex]1.\overline{923076}[/tex]
x = [tex]1\frac{12}{13}[/tex]

A colony of 36,000 bacteria grows continuously at a rate of 12%. How many bacteria will there be in 2 years?
Answer:
45158
Step-by-step explanation:
Since the colony grows at a rate of 12%, after 2 years there will be [tex]36000\cdot 1.12^2 = 45158.4[/tex] bacteria. Since you probably can't have part of a bacteria, you round to 45158.
Answer:
45158
Step-by-step explanation:
Since the colony grows at a rate of 12°/• , after 2 years there will be 36000.
1.12 power of 2 = 45158.4 bacteria.
And you cant have part of a bacteria
you round it to
45158.

∠ QPR = 64.5°
Step-by-step explanation:
The chord- chord angle QPR is half the sum of the arcs intercepted by the angle and its vertical angle, then
∠ QPR = [tex]\frac{1}{2}[/tex] (QR + ST ) = [tex]\frac{1}{2}[/tex] (98 + 31)° = 0.5 × 129° = 64.5°
A train travels 360 km at a uniform speed, if speed has been increased it will take one hour less for the same journey then find the speed of the train.

f(t) = 3t^3 - 4t + 6t^2 and g(n) = 5t^3 + 2t^2 - 3t. What is f(t) - g(t)
Answer:
- 2t³ + 4t² - t
Step-by-step explanation:
f(t) - g(t)
= 3t³ - 4t + 6t² - (5t³ + 2t² - 3t) ← distribute parenthesis by - 1
= 3t³ - 4t + 6t² - 5t³ - 2t² + 3t ← collect like terms
= - 2t³ + 4t² - t
the population of alaska is approximately 6.5 * 10^(5) people the populatio of illinois's is about 1.3 * 10^(7)people. how many times greater is the population of Illinois in the population of Alaska
Answer:
20 times greater
Step-by-step explanation:
Given the following
Population of alaska = 6.5 * 10^(5) people
Population of illinois's = 1.3 * 10^(7)people.
To know the number of times population of Illinois in the population of Alaska, we will take their population ratio;
Ratio = Population of illinois's /Population of alaska
Ratio = 1.3 * 10^(7)/6.5 * 10^(5)
Ratio = 0.2 * 10^7-5
Ratio = 0.2 * 10^2
Ratio = 20
Hence the population of Illinois is 20 times greater than population of alaska

Here
cos25°=BC/AB=8/c
c=8/cos25°
so cos function is helpful here
really a dum.beannie
Answer:
b) cos25
c = 7.248 or 7.2
Step-by-step explanation:
Cosine = [tex]\frac{adjacent}{hypothenuse}[/tex]
Cos 25 = [tex]\frac{8}{c}[/tex]
Cos of 25 is 0.906
0.906 = [tex]\frac{8}{c}[/tex]
Multiply 8 on both sides:
0.906 x 8 = [tex]\frac{8}{c}[/tex] x 8
7.248 = c

Answer: The new co-ordinates of A ( 2 ,-6)
Step-by-step explanation:
Type of transformation change to co-ordinate point
Vertical translation up 'd' units (x,y)→(x , y+d)
Vertical translation down 'd' units (x,y)→(x , y-d)
Horizontal translation right 'c' units (x,y)→(x+c , y)
Horizontal translation left 'c' units (x,y)→(x-c , y)
Reflection over x-axis (x,y) →(x , -y)
Reflection over y-axis (x,y) →(-x , y)
Given the original vertex A ( -2 ,3)
a) First reflection over x-axis ( -2 ,3) →(-2 , -3)
b) Vertical translation down '3' units so it changes (-2 , -3)→(-2 , -3-3)
(-2,-3)→(-2 ,-6)
and
c) The Horizontal translation right '4' units
now it changes ( -2 ,-6) → (-2+4,-6)→(2 ,-6)
Final answer:-
The new co-ordinates of A ( 2 ,-6)
