Mark should have rounded 271 to 300 and rounded 582 to 600: 300 + 500 = 900
Answer:
Mark should have rounded 271 to 300 and rounded 582 to 600: 300 + 500 = 900
Step-by-step explanation:
Rounding to the nearest hundred means rounding 271 to 300 and 550 to 600.
Think of it as
271 changes to 0.271
The 7 would be in the hundredths place.
7 is greater than 5; therefore, round up.
Now you have 0.3, change this back to it's normal decimal places to get 300.
550 changes to 0.550
Where the second 5 would be in the hundredths place.
5 is equal to 5; therefore, round up.
Now you have 0.6, change this back to it's normal decimal places to get 600.
Mark rounded to the nearest place which is not the same.

Answer:
C.
Step-by-step explanation:
14/3 = 4.66
/2/=2.33
-14/4 = -3.5
So the numbers are 4.66, 4.3, 2.33, 1.3, -2 and -3.5
So the numbers are -14/4, -2, 1.3,/2/, 4.3, 14/3

A rectangle has a perimeter of 26 inches. All of its side lengths are doubled to create a new rectangle.
a. How does the perimeter of the new rectangle compare to the perimeter of the original rectangle?
b. How does the area of the new rectangle compare to the area of the original rectangle?
Answer:
a) the new perimeter is 2 times the old perimeter
b) the new area is 4 times the old area
Step-by-step explanation:
b) the doubling of the length and width affects the area formula like this:
old triangle area formula = 1/2bh
new triangle area formula = 1/2(2b)(2h), you see the 2 x 2 causes the area to be 4 fold

what is the mistake?
x-5=17+5
x=22
choose one:
- unknown value isn't 22
-work is not shown on both sides
-wrong inverse operation is used
-17+5 is not 22.
Answer:
x = 17+5-5
x=17
so this equation is wrong

100% of what number is 27? Provide an exact fraction answer
Answer:
Your answer is 27
I hope I helped, would appreciate brainliest! ;)
Step-by-step explanation:
'Percent (%)' means 'out of one hundred':
27% = 27 'out of one hundred',
p% is read p 'percent',
27% = 27/100 = 27 ÷ 100
Calculate percentage:
'Percentage' is obtained by multiplying 100 by 27%
27% of 100 is equivalent to multiplying them:
27% × 100 = ?
27% × 100 =
(27 ÷ 100) × 100 =
(27 × 100) ÷ 100 =
2,700 ÷ 100 =
27
Proof.
How do we check the result?
If 27% × 100 = 27 =>
Divide 27 by 100...
... And see if we get as a result: 27%
Note:
100/100 = 100 ÷ 100 = 100% = 1
Multiply a number by the fraction 100/100,
... and its value doesn't change.
n/100 = n%, any number.
Calculate the percent value:
27 ÷ 100 =
0.27 =
0.27 × 100/100 =
(0.27 × 100)/100 =
27/100 =
27%
So we have proved that the calculations are correct.
Answer:
Percentage of
27% of 100 = 27
Answer:
27%
Convert fraction (ratio) 27 / 100 Answer: 27%
What is the equation of the line perpendicular to y = 1/4x – 5 through the point (4,3)?
y-yi=m(x-xi)
y-3=1/4(x-4)
y-3=x-4/4
4y-12=x-4
4y+x-12+4=0
4y+x-8=0
so the equation of
the line perpendicular

Answer:
x=128
Step-by-step explanation:
180-52=128
Answer: x= 128 degrees
Step-by-step explanation:
Angle “x” and angle with measure of 52 degrees are a linear pair.
Linear pairs sum to 180.
52+x=180. Subtract 52 from both sides.
X= 128
*OR you can use angles around a point sum to 360 degrees.
52+38+142+x = 360. Combine like terms.
232+x= 360. Subtract 232 from both sides.
X= 128

Final answer: x=0 m:3 and x=-6 m:2
Step-by-step explanation:
1. 4x³(x²+12x+36)- Divide by greatest common factor, to simplify.
2. 4x³(x+6)(x+6)- Factored
3. 4x³ = 0 Set each factor equal to zero
4. x+6=0 x+6=0
So, x= -6, two times, mulitiplicity 2
So, 4x³=0, so x=0 three times, mulitiplicity 3
Final answer: x=0 m:3 and x=-6 m:2

Answer:
C. [tex]\sqrt{3x^2+21x}[/tex]
Step-by-step explanation:
When one multiplies two radicles, one multiplies each term in the radical by the term in the other radical, then one simplifies the result and puts the radical sign over the result. If there are any perfect squares one will take the terms out. In this scenario, such is not the case.
[tex]\sqrt{3x}*\sqrt{x+7}\\\\\sqrt{3x(x+7)}\\\\\sqrt{3x^2+21x}[/tex]

A town has a population of 13000 and grows at 2.5% every year. What will be the population after 5 years, to the nearest whole number?
The population of the town after 5 years will be 147089 (approx).
Step-by-step explanation:
The exponential growth equation is given by :-
f(x)=A(1+r)^x...(*)
, where A = initial population , r= rate of growth ( in decimal) and x is time.
As per given , we have
A= 13000
r=2.5%=0.025
x= 5 years
Using (*), the population of the town after 5 years would be :
f(5)=13000(1+0.025)^5=13000(1.025)^5\\\\=13000(1.13140821289)=14708.306767614708.3067676\approx147089
Hence, the population of the town after 5 years will be 147089 (approx).

Answer:
6 is the answer for your box :) Double checked :)
Step-by-step explanation:
25.12 = 1/3(12.56h)
multiply both sides by 3 to get rid of the fraction
75.36 = 12.56h
divide both sides by 12.56
6 = h
h = 6
Answer:
h = 6
Step-by-step explanation:
25.12=12.56/3 h
25.12 x (3/12.56) = h
h = 6

Find the value of 3y + 4 given that - 2y + 6 = 2.
Simplify your answer as much as possible.
Answer:
10
Step-by-step explanation:
to find the answer for 3y + 4 we have to find the value of y.
we can find that by using the second equation.
-2y+6=2
-2y+6-2 =0 (subtract 2 from both the sided)
4= 2y (we will bring the -2y to the other side of the equation and then subtract the 6-2 to get the 4)
4/2=y (divide by 2 on both the sides)
∴ y=2
now we will plug in the y of value that we see as -2 into the first equation.
∴ 3y+4 will become
= 3(2)+4
=6+4
=10
hope this helps!!
