which value of h makes 8+h/10=1 a true statement
Answer:
h=2
Step-by-step explanation:
8+h/10=1
multiply the 1 by 10
8+h=10
subtract 8 from 10
h=2
If the statement is true, the value of h = 2.
What is a statement?
Mathematical statement - a statement of a mathematical relation math, mathematics, maths - a science (or group of related sciences) dealing with the logic of quantity and shape and arrangement equation - a mathematical statement that two expressions are equal.
What is true statement?
Students understand that an equation is a statement of equality between two expressions. When values are substituted for the variables in an equation, the equation is either true or false. Students find values to assign to the variables in equations that make the equations true statements.
Given,
(8+h)=10
given, the equation is true statement.
Therefore, 8+h = 10
h = 10 - 8
h = 2

What is the value of A and B and if you can please show how you got that answer
Answer:
a = 4.5 units
b = 7.5 units
Step-by-step explanation:
By using mean proportional theorem in the ΔACB,
ΔACB ~ ΔADC ~ ΔCDB
[tex]\frac{AD}{CD}=\frac{CD}{DB}[/tex]
[tex]\frac{8}{6}=\frac{6}{a}[/tex]
a = [tex]\frac{6\times 6}{8}[/tex]
a = 4.5
[tex]\frac{AB}{CB}=\frac{CB}{DB}[/tex]
[tex]\frac{(a+8)}{b}=\frac{b}{a}[/tex]
Since a = 4.5
[tex]\frac{4.5+8}{b}=\frac{b}{4.5}[/tex]
b² = 4.5 × 12.5
b = √56.25
b = 7.5 units
Therefore, a = 4.5 units and b = 7.5 units will be the answer.

Here is the question to the last post
Hi!
So the first thing to do is to combine the common terms on each side.
On the left side, 13 and 2a cannot be put together because 2 has a multiplier that 13 does not.
On the right side, however, there are two numbers with the multiplier a. Add those together!
3a + 2a = 5a.
13 + 2a = 5a - 14
Now we want to isolate a to one side. Let's do the right side.
To do this, we have to subract 2a from both sides to get a on only one side.
13 + 2a - 2a = 5a - 2a - 14.
Subract.
13 = 3a - 14.
We have to do the same for the 14 on the right side. Instead, since the number is being subracted from 3a, we have to add it to both sides.
13 + 14 = 3a + 14 - 14.
27 = 3a
a = 9.

4) The population of the city in the year 2000 was 50000. The population is decreases by 0.95 each year
Step-by-step explanation:
a) Given an equation:
ax² + bx + c = 0
The equation would have imaginary solutions if b² - 4ac is negative. That is:
b² - 4ac < 0
Given an equation: 3x²+2kx+2=0
a) If k = -5
a= 3, b = 2k = 2 × -5 = -10, c= 2
b² - 4ac = (-10)² - 4(3)(2) = 76 > 0
It would not produce imaginary solutions
b) If k = -3
a= 3, b = 2k = 2 × -3 = -6, c= 2
b² - 4ac = (-6)² - 4(3)(2) = 12 > 0
It would not produce imaginary solutions
c) If k = -1
a= 3, b = 2k = 2 × -1 = -2, c= 2
b² - 4ac = (-1)² - 4(3)(2) = -23 < 0
It would produce imaginary solutions
d) If k = 2
a= 3, b = 2k = 2 × 2 = 4, c= 2
b² - 4ac = (4)² - 4(3)(2) = -8 <0
It would produce imaginary solutions
e) If k = 3
a= 3, b = 2k = 2 × 3 = 6, c= 2
b² - 4ac = (6)² - 4(3)(2) = 12 > 0
It would not produce imaginary solutions
f) If k = -5
a= 3, b = 2k = 2 × 4 = 8, c= 2
b² - 4ac = (8)² - 4(3)(2) = 40 > 0
It would not produce imaginary solutions
2)
A. Distribute 4 to the quantity ( x+1). to get:
1/2 x+12=8+4x+4
B. Add − 8 to each side of the equation. to get:
1/2 x+4=4( x+1)
C. Distribute 12 to the quantity ( x+1). This is not correct
D. Multiply each side of the equation by 2. to get:
x + 24 = 16 + 8(x +1)
F. Add together the 8 and the 4 on the right side of the equation. This is not correct
G. Multiply the left side of the equation by 2 to eliminate the fraction. This is not correct
3)
[tex]f(x)=x^2-2(r-s)x+(r-s)^2+(r+s)\\f(x)=x^2-2rx+2sx+r^2+s^2-2rs+r+s\\f(x)=x^2+r^2+s^2-2rs-2rx+2sx+r+s=(r-x-s)^2+(r+s)\\f(x)=(r-x-s)^2+(r+s)[/tex]
4) P( x )=50,000 ( 0.95 )^x, where x represents the number of years after the year 2000
At the year 2000, x = 0 therefore
[tex]P(x)=50000(0.95)^x=50000(0.95)^0=50000[/tex]
Since 0.95 is less than 1, it represent a population decay. 0.95 is the common ratio
The population is decreases by 0.95 each year
Find the measure of angle 2... State what the relationship is between angle 2 and the 18 degree angle
Relationship: ________
Degree measure of angle 2: _______
Answer:
-The Relationship:
Both [tex]\angle 2[/tex] and the [tex]18\textdegree[/tex] angle are supplementary.
The measure of [tex]\angle 2[/tex]:
[tex]\angle 2 = 162\textdegree[/tex]
Step-by-step explanation:
-The relationship about both [tex]\angle 2[/tex] and the [tex]18\textdegree[/tex] angle, is that they are supplementary, which they both add up to [tex]180\textdegree[/tex].
-To find the measure of [tex]\angle 2[/tex], you need to subtract [tex]18[/tex] from [tex]180[/tex] to get the actual angle measurement of [tex]\angle 2[/tex]:
Finding the measure of [tex]\angle 2[/tex]:
[tex]180 - 18 = 162[/tex]
[tex]\angle 2 = 162\textdegree[/tex]
So, now you have the measure of [tex]\angle 2[/tex] .

Find the area ?
Solution:
Area = ( 3x - 1 ) × ( 5x + 2 )
= 3x ( 5x + 2 ) - 1 ( 5x + 2 )
= 15x² + 6x - 5x - 2
= 15x² + x - 2
Thus, the area is 15x² + x - 2 .
Which best explains whether or not triangles RST and ACB are congruent?
The figures are congruent. ΔRST can be mapped to ΔACB by a reflection over the x-axis and a translation 2 units to the left.
The figures are congruent. ΔRST can be mapped to ΔACB by a reflection over the y-axis and a translation 2 units down.
The figures are not congruent. Point R corresponds to point A, but S corresponds to B and T corresponds to C.
The figures are not congruent. Point R does not correspond with point A.
Answer:
Correct option: first one
Step-by-step explanation:
If we reflect the triangle RST over the x-axis, the y-coordinate of each point will have the sign switched, so the point S would be in (1, -5), the point R would be in (1, -1) and the point T would be in (4, -1)
Then, if we translate the resulting points 2 units to the left, we would have:
S = (-1, -5) -> matches point C
R = (-1, -1) -> matches point A
T = (2, -1) -> matches point B
So the triangles are congruent, and we can map from triangle RST to triangle ACB with a reflection over the x-axis and a translation of 2 units to the left.

Answers:
7 grams47000 grams18.5 kg8300 g22000 mg0.135 kgLook at the attached picture
Hope it will help you
Good luck on your assignment....
Answer:
7000 mg = 7 g
18500 g = 18.5 kg
22 g = 22000 mg
4.7 kg = 4700 g
8.3 kg = 8300 g
135000 mg = 135 g
Step-by-step explanation:
First we need to use some important conversion rates so I will write them for below
1 Milligram (mg) = 0.001 Grams (g)
1 Gram (g) = 0.001 Kilogram (Kg)
1 Gram (g) = 1000 Milligrams (mg)
1 Kilogram (Kg) = 1000 Grams (g)
Using the above conversion rates we can solve these questions
Question 1
7000 mg = ? g
Using the information at the top 1 Milligram (mg) = 0.001 Grams (g) so,
0.001 × 7000 = 7 grams
Question 2
18500 g = ? kg
Using the information at the top 1 Gram (g) = 0.001 Kilogram (Kg) so,
18500 ÷ 1000 = 18.5 kg
Question 3
22 g = ? mg
Using the information at the top 1 Gram (g) = 1000 Milligrams (mg) so,
22 × 1000 = 22000 mg
Question 4
4.7 kg = ? g
Using the information at the top 1 Kilogram (Kg) = 1000 Grams (g) so,
4.7 × 1000 = 4700 g
Question 5
8.3 kg = ? g
Using the information at the top 1 Kilogram (Kg) = 1000 Grams (g) so,
8.3 × 1000 = 8300 g
Question 6
135000 mg = ? g
Using the information at the top 1 Milligram (mg) = 0.001 Grams (g) so,
0.001 × 135000 = 135 grams

Answer:
Relative frequency is 7.41% or 0.0741
Step-by-step explanation:
Given
The Attached Table
Required
Calculate the relative frequency of the class with lower limit 27
Relative Frequency is calculated by dividing individual frequency by the total frequency
Mathematically,
[tex]Relative\ Frequency = \frac{Individual\ Frequency}{Total\ Frequency}[/tex]
The total frequency of the given data is 6+8+4+2+5+2
[tex]Total\ Frequency = 27[/tex]
The class with lower limit 27 has a frequency of 2;
Hence;
[tex]Relative\ Frequency = \frac{Individual\ Frequency}{Total\ Frequency}[/tex] becomes
[tex]Relative\ Frequency = \frac{2}{27}[/tex]
[tex]Relative\ Frequency = 0.07407407407[/tex]
[tex]Relative\ Frequency = 0.0741[/tex] (Approximated)
You may also leave your answer in percentage form
[tex]Relative\ Frequency = 0.0741 * 100\%[/tex]
[tex]Relative\ Frequency = 7.41 \%[/tex]
Hence, the relative frequency is 7.41% or 0.0741
