which of the following is the ratio of 3 km to 300m
°10 is to 1
° 1 is to 10
° 100 is to 1
°1 is to 100
Answer:
10 is to 1
Step-by-step explanation:
First convert both the distances to the same unit. So,3 km = 3 × 1000 m = 3000 m. Thus,the required ratio, 3 km : 300 m is 3000 : 300 = 10 : 1.
Answer:
option A
Step-by-step explanation:
wkt 1km=1000m
3km=3000m
3000m:300m = 10:1
thus 3km:300m = 10:1

The sum of four angles in a pentagon is 440°. Find the missing angle
measure.
180°
Answer:
The measure of the missing angle x is:
m∠x = 100°Step-by-step explanation:
Let 'x' be the missing angle of a Pentagon
Given that the sum of four angles in a pentagon is 440°.
We know that:
The sum of internal angles in a simple pentagon is 540°.Thus,
we get the equation such as:
sum of four angles + x = 540°
440° + x = 540° ∵ sum of four angles = 440°
subtract 440° from both sides
440° + x - 440° = 540° - 440°
x = 100°
Therefore, the measure of the missing angle x is:
m∠x = 100°If the time is 9:20 am. What time will it be after three hours and fifty minutes?
Answer:
The time would be 1:10 pm.
Step-by-step explanation:
9:20 + 3 hours is 12:20.
50 minutes after 12:20 is 1:10.
Answer:
1:10
Step-by-step explanation:
Hey there
to solve this problem think 9:20 and 3:50 as ratios. In this problem we will add these too
9:20 + 3:50= 12:70
so, if it is 12:70. in one hour there is 60 and in the 12:70 it 70. so we add one more hour it will be 1:10
= 1:10

Answer:
4th term is 274.4 cm
5th term is 192.08 cm
Step-by-step explanation:
Here, we want to get the 4th and 5th term
Let us get the common ratio;
That would be ;
392/560 = 560/800 = 0.7
The 4th term will be ar^3
= 800 * 0.7^3 = 274.4
The 5th term will be ar^4
= 800 * 0.7^4 = 192.08

Nadeen started with 18 tokens and will lose 3 with every game he/she/they play.
The equation that would represent this is a) 18 - 3x. b, when distributed, is also 18 - 3x.
3(6 - x) ---> multuply 3 with 6 and 3 with x
18 - 3x
Answer:
Option A
Step-by-step explanation:
Nadeen started with 18 tokens.
Since each game costs 3 tokens, we can see how much she spent using:
[tex]3x[/tex]
To find how many tokens she have left, we can use:
18 - 3x
Option A should be the correct answer!

Which choice best represents the balance of a savings account at the end of 6 years if the simple interest earned each year is 6.5% and the principal is $1,300?
Answer:
$507.00.
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6.5%/100 = 0.065 per year,
then, solving our equation
I = 1300 × 0.065 × 6 = 507
I = $ 507.00
The simple interest accumulated
on a principal of $ 1,300.00
at a rate of 6.5% per year
for 6 years is $ 507.00.

find the polynomial that represents the area of a rhombus whose diagonals are ( 2P -4) and( 2P +4)
Answer:
The polynomial that represents the area of a rhombus is [tex]A = 2\cdot P^{2}-8[/tex].
Step-by-step explanation:
The area formula for the rhombus is defined below:
[tex]A = \frac{D\cdot d}{2}[/tex] (1)
Where:
[tex]A[/tex] - Area of the rhombus.
[tex]D[/tex] - Greater diagonal.
[tex]d[/tex] - Lesser diagonal.
If we know that [tex]d = (2\cdot P -4)[/tex] and [tex]D = (2\cdot P + 4)[/tex], then the area formula of the rhombus:
[tex]A = \frac{(2\cdot P - 4)\cdot (2\cdot P +4)}{2}[/tex]
[tex]A = \frac{4\cdot P^{2}-16}{2}[/tex]
[tex]A = 2\cdot P^{2}-8[/tex]
The polynomial that represents the area of a rhombus is [tex]A = 2\cdot P^{2}-8[/tex].

PLS HELP, 100 BRAINLIEST POINTS. FIND BOTH AREA AND PERIMETER. The following three shapes are based only on squares, semicircles, and quarter circles. for each shape, find the area and perimeter. Give your answer as a completely simplified exact value in terms of pi.
Answer:
P = 8πA = 32π - 64Step-by-step explanation:
Given
Square of 8 cm and part of the circle of same radiusPerimeter of the shape is sum of two quarter circles:
P = 2*1/4*2πr = πrP = 8πThe area is calculate as follows:
Half of the area of the shape is the difference of the quarter-sector of the circle and half-area of the square
1/2A = 1/4πr² - 1/2*8²A = 1/2π*8² - 64 = 32π - 64A = 32π - 64The answer is
Perimeter = 8π
Area = 32π - 64

School A rented and filled 5 vans and 9 buses with 499 students. School B rented and filled 10 vans and 9 buses with 539 students. How many students can a bus carry?
Given:
School A rented and filled 5 vans and 9 buses with 499 students.
School B rented and filled 10 vans and 9 buses with 539 students.
To find:
The number of student a bus can carry.
Solution:
Let x be the number of student a van can carry and y be the number of student a bus can carry.
School A rented and filled 5 vans and 9 buses with 499 students.
[tex]5x+9y=499[/tex] ...(i)
School B rented and filled 10 vans and 9 buses with 539 students.
[tex]10x+9y=539[/tex] ...(ii)
Subtract (i) from (ii).
[tex]10x+9y-5x-9y=539-499[/tex]
[tex]5x=40[/tex]
[tex]x=\dfrac{40}{5}[/tex]
[tex]x=8[/tex]
Putting x=8 in (i), we get
[tex]5(8)+9y=499[/tex]
[tex]40+9y=499[/tex]
[tex]9y=499-40[/tex]
[tex]9y=459[/tex]
Divide both sides by 9.
[tex]y=\dfrac{459}{9}[/tex]
[tex]y=51[/tex]
Therefore, a bus can carry 51 students.
