Complete the statement that explains how to compare 0.4 and 0.12.
I know that 0.4 is
than 0.12 because
is greater than
less
greater
Answer:
0.4 is 40 percent of something because 100 percent is 1 x something. On the other hand, 0.12 is 12 percent of something because 0.12 x something will get you 12 percent of the value. Therefore, 0.4 is 40 percent of a thing while 0.12 is 12 percent of a thing and 0.4 is bigger than 0.12
Step-by-step explanation:

Solve the simultaneous equations
x + 6y = 20
x + 3y = 14
x =
Y=
Answer:
x = 8, y = 2
Step-by-step explanation:
Multiply the second equation by -2:
x + 6y = 20
-2x - 6y = -28
Add the equations and simplify:
-x = -8
x = 8
Plug x = 8 back into the first equation and solve for y:
8 + 6y = 20
6y = 12
y = 2
Answer:
x=8
Y=2
or
(x,y)=(8,2)
Step-by-step explanation:
x+6y=20
x+3y=14
solve the equation for x
x+6y=20
x=14-3y
substitute the given value of x into the equation
x+6y=20
14-3y+6y=20
14+3y=20
3y=20-14
3y=6
3y/3=6/3
y=2.
substitute the given value of y into the equation
x=14-3y
x=14-3×2
x=14-6
x=8.
the possible solution of the system is the ordered pair (x,y)
(x,y)=(8,2)
or
x=8
Y=2
Proof:
Check if the given ordered pair is the solution of the system of equations
8+6×2=20
8+3×2=14
simply the equalities
20=20
14=14
since all of the equalities are true, the ordered pair is the solution of the system
(x,y)=(8,2)
In 1980, the population of a town was 2000 people. The exponential function P(t)=2000(1.05)t models the population of the town since 1980. Which statements are true regarding the population of the town? Select THREE that apply.
A.
The population has increased by 5% each year since 1980.
B.
The population has increased by 105% each year since 1980.
C.
The population has increased by 5 people each year since 1980.
D.
Each year since 1980, the population is 105% of the population of the previous year.
E.
Each year since 1980, the population is 1.05 times the population of the previous year.
Answer:
B. The population has increased by 105% each year since 1980.
D. Each year since 1980, the population is 105% of the population of the previous year.
E. Each year since 1980, the population is 1.05 times the population of the previous year.
Step-by-step explanation:
From the question, we are given the exponential function:
The exponential function P(t)=2000(1.05)^t models the population of the town since 1980.
Exponential growth rate =
P(t) = P(1 + r)^t
Where r = growth rate in percentage
P(t) = Size of the population after t years
t = time in years
Hence,
From the formula above, we can say =
1 + r = 1.05
r = 1.05 - 1
r = 0.05
Converting to percentage = 0.05 × 100 = 5%
1.05 can also converted to percentage and this = 1.05 × 100 = 105 %
The population has increased by 105% each year since 1980.
Hence, Options, B, D and E is correct

In the figure below, what is the value of x if angles m and n are congruent?
We want to find the measure of x given that we know that m and n are congruent.
The measure of x is 116°.
Two angles are congruent if they have the same measure.
Then we have ∠n = ∠m
We also know that the sum of all interior angles of a triangle is equal to 180°, then if we look at the smaller triangle we have that:
114° + ∠n + ∠m = 180°
∠n + ∠m = 180° - 114° = 66°
Knowing that these measures are equal we can write:
2*∠m = 66°
∠m = 66°/2 = 33°
Now that we know the measure of m, we can do the same thing for the larger triangle:
∠x + ∠m + 31° = 180°
∠x + 33° + 31° = 180°
∠x = 180° - 64° = 116°
The measure of x is 116°.

Applying the exterior angle theorem and the sum of triangles, the value of x in the figure is: [tex]\mathbf{x = 64^{\circ}}[/tex]
Recall:
Sum of triangles = 180 degrees
Exterior angle = sum of two interior opposite angles
Since we know that angles m and n are congruent, therefore:
[tex]m = \frac{1}{2} (180 - m \angle RTU)[/tex]
Substitute[tex]m = \frac{1}{2} (180 - 114)\\\\\mathbf{m = 33^{\circ}}[/tex]
Find x (exterior angle of triangle SUV):
[tex]x = 31 + m[/tex] (exterior angle of a triangle theorem)
Substitute[tex]x = 31 + 33\\\\\mathbf{x = 64^{\circ}}[/tex]
Therefore, applying the exterior angle theorem and the sum of triangles, the value of x in the figure is: [tex]\mathbf{x = 64^{\circ}}[/tex]

Answer:
[tex]3 \frac{7}{12}[/tex]
Step-by-step explanation:
1 - multiply the 1/2 out to make the denominators the same (Ignore the 4 for now)
To make 2 equal 12 you multiply by 6 and what you do to the bottom you do to the top.
[tex]\frac{1}{2}(\frac{6}{6}) = \frac{6}{12}[/tex]
2 - Now solve
Now we need to know what 4 1/12 - 6/12 equals.
1-6 is -5 so we will take out of the whole number to continue this subtraction
3 12/12 - 5/12
After subtracting that out we're left with

A pile of pebbles has a weight of 95 kg.
Some of the pebbles put into a small bag.
The rest of the pebbles is put into a large bag.
The pebbles in the large bag weighs 45 kg more than the pebbles in the small
What is the weight of the pebbles in the large bag?
Answer:
70kg
Step-by-step explanation:
s = small bag
b = big bag
Equations
s + b = 95
s + 45 = b
plug in
s + s + 45 = 95
2s + 45 = 95
2s = 50
s = 25
plug in to find big bag
25 + 45 = b
70 = b
Answer:
The weight of the pebbles in the large bag is 70kg.
Step-by-step explanation:
This looks like a substitution algebra problem. To do this, I’m going to mark the large bag with (L) and the small bag with the variable, (s). I will make first 2 equations to show the value. The first equation would be L=45+s. The second equation would be 95=L+s. Since L is literally 45+s, add this into the 2nd equation. This would be 95=45+s+s. You should have 95= 45+2s and you would subtract 45 from both sides then. Finally, divide 2s by 2 to get what the small bag weighs, (which is 25kg). To find the large bag’s weight, use the first equation to find the answer. L= 45+s or 25. The answer would bring us to 70 kg.
