As of July 1, 2014, the population of India was about 1,267,000,000. How can you write this number in scientific notation?
1. Move the decimal point to the right of the first digit. What is the first factor?
2. Count the number of digits after the decimal point. How many places did you move the decimal point?
3. Did you move the decimal point to the right or to the left? What does this tell you about the power of 10 in the second factor?
4. What is the second factor written as a power of 10?

Solve problems a,b,c,d,e,and f. With the graph
Answers:
a. f(-4)=2
b. f(0)=0
d. f(-5)=0
e. x when f(x)=-2 answer: 2
f. x when f(x)=0 answer: 0
Sorry, I can’t answer c. f(3)= because when x is three from the x-axis on the graph, the line that meets 3 from the x-axis doesn’t show a whole number y-coordinate on the graph :(
But I hope this helps and answers your question :)

Start with a male and a female rabbit. After a month, they mature and produce a litter with another male and female rabbit. A month later, those rabbits reproduce and out comes — you guessed it — another male and female, who also can mate after a month. After a year, how many rabbits would you have?
Answer:
24 thereabouts
Step-by-step explanation:
Well every two months there are two new rabbits so I multiplied two and twelve. This got me twenty-four. I hope this helps! :) I don't know if this is right or not I attempted this in my head.

What are the measures of angles B and D?
A. ∠B = 55°, ∠D = 55°
B. ∠B = 55°, ∠D = 125°
C. ∠B = 97°, ∠D = 97°
D. ∠B = 83°: ∠D = 97°
Answer:
One basic property of a parallelogram is that opposite angles have the same value. Hence angle B = angle D. (2n+15°) = (3n-5°). Then have one side for the unknown. The equation will be 3n=2n+15°+5°. To get the n, simplify the equation: 3n-2n = 20° or n = 20°. Afterwards substitute the value of n to the angles. Angle B = (2(20)+15), Angle D = (3(20)-5). Lastly, simplify the equations. Angle B = (40+15°) = 55° and Angle D = (60-5°)=55°. Therefore the value of angles B & D are both 55°.

Answer:
1. x = 102. x = -63. 944. x = 2Step-by-step explanation:
1. F and M are equal angles and sum of internal angles = 180, so
2(7x + 5) + 30 = 18014x + 10 + 30 = 18014x = 140x = 102. Triangle is equilateral as all angles are equal, so all sides are equal:
4x + 43 = -2x + 74x + 2x = 7 - 436x = -36x = -63. Isosceles triangle with equal angles of R and T:
4x + 7 = 7x - 20 (using values as per picture not text)7x - 4x = 20 + 73x = 27x = 9Angle S is
180 - 2(4*9 + 7)= 180 - 2(43) = 180 - 86 = 944. Angle 2 is supplementary with 156 as isosceles triangles and vertical angles are equal, therefore:
180 - 156 = 6 + 9x24 = 6 + 9x18 = 9xx = 26. Consider the inequality 12<-3 (x + 4). Which value of xis part of the solution set of this inequality?
Answer:
x < -8
General Formulas and Concepts:
Pre-Alg
Order of Operations: BPEMDASEquality PropertiesStep-by-step explanation:
Step 1: Define inequality
12 < -3(x + 4)
Step 2: Solve for x
Distribute -3: 12 < -3x - 12Add 12 to both sides: 24 < -3xDivide -3 on both sides: -8 > xRewrite: x < -8Here we see that any value x that is smaller than -8 would work.
Temperatures have been falling steadily at 5°F each day. Which number
sentence shows how to find the change in temperature 7 days from today's
A)5 + 7 = 12°F
B)none of these
C)-5* 7 = -35°F
D)O 7-5 = 2°F
answer: none of these
T−7×−5 = Tn
Let T equal the present temperature
7 = the number of days
-5= the drop each day
Let Tn = the new temperature
the sum of three times a number x and nine"
Answer:
3x+9
Step-by-step explanation:
you are multiplying 3 and x because it says "three times a number x" which means 3x and you are adding it to 9 which is 3x+9.
Choose the linear equation written in slope-intercept
form that matches each graph.
Answer:
D
Step-by-step explanation:
y-intercept or "b":
the line touches the y-axis at -4
slope:
the line rises 1, runs 1 every time
equation:
the y-intercept of -4 combined with the slope of 1/1 is the equivalent of
y=1x/1-4 OR in a more simplified format: D, y = x - 4

Isosceles trapezoids ABCD and WXYZ are similar to each other. Label the trapezoids with the given side measures AB=6, WX=12, and, ZW=9
Use similar figures and the given side lengths to complete the following prompts. Enter numerical answers only. If necessary, enter decimal numbers rounded to the nearest tenth of a number. Do not enter your answer as a fraction number.
1. DA=
2.CB=
3.XY
4.If YZ=8 then CD=
5. if the perimeter of the trapezoid ABCD =
6. the perimeter of trapezoid WXYZ =
Answer: Hello this is my first time answering!
DA= 4.5
CB=4.5
XY=9
If YZ=8 then CD=4
Perimeter of trapezoid ABCD=19
Perimeter of trapezoid WXYZ=38
Step-by-step explanation:
I am almost positive the scale is 0.5/1 this means that for DA it would be 4.5. Of course, if DA was 4.5 then so would CB. Everything is half of the second trapezoid.

To replace the trees destroyed by typhoon Yolanda, the forestry department of Tagaytay has developed a ten-year plan. During the first year they will plant 100 trees. Each succeeding year, they will plant 50 more trees than they planted the year before.
Answer:
a. 1,000 trees
b. 3,250 trees
Step-by-step explanation:
a. How many trees will they plant during the fifth year?
b. How many trees will they have planted by the end of the tenth year?
Using the sum of an arithmetic progression formula
Sn = n/2 {2a+(n-1)d}
Where,
Sn = Sum of an n terms
n = number of terms
a = first term
d = common difference
a.
n = 5
a = 100
d = 50
S5 = n/2 {2a+(n-1)d}
= 5/2 {2*100 + (5-1)50}
= 5/2 {200+(4)50}
= 5/2{200 + 200}
= 5/2(400)
= 2,000 / 2
= 1,000
S5 = 1,000 trees
b. Sn = n/2 {2a+(n-1)d}
n = 10
a = 100
d =50
S10 = 10/2{2*100 + (10-1)50}
= 5{200 + (9)50}
= 5{200 + 450}
= 5(650)
= 3,250
S10 = 3,250 trees

I'm confused on how to do that?
Answer:
(8, 0), (12, 4), (16, 8)
Step-by-step explanation:
m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
(20, 12)
(4, - 4)
m = [tex]\frac{-4-12}{4-20}[/tex] = 1
y - 12 = (1)(x - 20)
y = x - 8
y = 8 - 8 = 0
y = 12 - 8 = 4
y = 16 - 8 = 8
O Perímetro de triângulo isósceles mede 24cm. Qual é a medida de comprimento dos lados congruentes sabendo-se que o lado não congruente mede 7cm de comprimento?
Answer:
La longitud de los lados congruentes =
B = 8.5cm
C = 8.5 cm
Step-by-step explanation:
El perímetro del triángulo isósceles mide 24 cm.
El lado no congruente mide 7 cm de largo.
Lados congruentes significa lados que son iguales o iguales entre sí.
El perímetro de un triángulo es =
Lado A + Lado B + Lado C
Por lo tanto,
24 = 7 cm + B + C
24 - 7 = B + C
17 cm = B + C
Los dos lados son congruentes,
B = C
Por lo tanto, 17 cm / 2
= 8.5 cm
La longitud de los lados congruentes =
B = 8.5 cm
C = 8.5 cm

Marcus and Jeremy both evaluated the expression −5^2 + 3. Marcus said the answer was −22. Jeremy said the answer was 28. Who is correct? Explain the error in the other student's work.
Answer:
Jeremy is correct
Step-by-step explanation:
Marcus and Jeremy both evaluated the expression −5^2 + 3. Marcus said the answer was −22. Jeremy said the answer was 28. Who is correct? Explain the error in the other student's work.
Marcus is wrong
This is because, Marcus calculated:
-5^2 + 3
= -25 + 3
= -22
This is wrong because it did not follow the rules which states that:
- × - = +
Jeremy calculation is shown below:
-5^2 + 3
-5 × -5 + 3
= 25 + 3
= 28
Jeremy is correct
Do these pairs of values (x and y) represent two quantities that are
proportional?
ху
3 12
520
624
9 36
Answer:
yes
Step-by-step explanation:
Each value of x multiplied by 4 gives the corresponding value of y, that is
3 × 4 = 12
5 × 4 = 20
6 × 4 = 24
9 × 4 = 36
Thus x and y are proportional and the constant of proportion is 4
