What number is 56% of 400? Show ALL of your work.
Answer: 224
Step-by-step explanation:
56% is the same as saying (56/100). When finding a percent of a number, you’re really setting up a ratio with the value x:
(56/100)=(x/400)
Then you just cross multiply:
(56 x 400)/100=x
x=224

Mode ??
Median ??
Answer:
No mode
Median 7
Step-by-step explanation:
Mode: The mode is the element that occurs most in the data set. In this case, all elements occur only once, so there is no mode.
Median: Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.
Answer:
Mode: no mode
No mode because there are no repeating numbers.
Median=7
Put in order from least to greatest- 1,6,7,42,81
Find the one in the middle- 7

Pythagorean theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
The length of the sand dune is 88 feet.
What is the Pythagorean theorem?Pythagorean theorem states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
We have,
Hypotenuse = 137 feet
One side length:
Horizontal length = 105 feet
Another side length = side = length of the sand dune.
Using the Pythagorean theorem we get,
137² = side² + 105²
18769 = side² + 11025
side² = 7744
side = √7744
side = 88 feet
Thus,
The length of the sand dune is 88 feet.

Marina Polyakova pays a total of $1150 per month for rent and electricity. It costs $650 more for rent per month than for electricity. What are the costs for each?
Answer:
900 and $250
Step-by-step explanation
Given data
Total cost of utilities per month =$1150
Let the cost of rent be x
And the cost of electricity be y
x+y=1150---------1
It costs $650 more for rent per month than for electricity
x=x+650-------2
From equation 1
x+x+650=1150
2x=1150-650
2X=$500
x=500/2
x=$250
Hence the cost of electricity is $250
And the cost of rent is $650+250
=$900

There is a guitar that originally costs $249.99. It is on sale for 15% off. You also have to pay 6% sales tax. How much will you pay for the guitar? Please show work!!!
Answer:
225.24099
Step-by-step explanation:
249.99(0.15) = 37.4985
249.99 - 37.4985 = 212.4915
212.4915(0.06) = 12.74949
212.4915 + 12.74949 = 225.24099

The power, P (watts) , of a car engine is proportional to the square of its speed, s ( m / s ) . When s = 35 , P = 1580 . Work out the power (to 1 DP) when the speed is 30 m / s
Answer:
P=2200 , K=35
Step-by-step explanation:
The power, P (watts), of a car engine is proportional to the square of its speed, k%28m%2Fs%29; it means if you have two different powers and speeds, you will have a proportion
P%3Ak%5E2=P%5B1%5D%3Ak%5B1%5D%5E2 or
P%2Fk%5E2=P%5B1%5D%2Fk%5B1%5D%5E2
When given:
k=35, P=2200
Work out the power P%5B1%5D (to 1DP) when the speed is k%5B1%5D=40%28m%2Fs%29
so,
P=2200
k=35
k%5B1%5D=40
and you need P%5B1%5D
2200%2F35%5E2=P%5B1%5D%2F40%5E2
2200%2F1225=P%5B1%5D%2F1600
1.79592=P%5B1%5D%2F1600
1.79592%2A1600=P%5B1%5D
P%5B1%5D=2873.5 watts
If the speed is 30 m per second. Then the power of the car engine will be 1160.8 watts.
What is proportion?A proportionate expression is one in which two items are equal.
The power, P (watts), of a car engine is proportional to the square of its speed s (m/s).
P ∝ s²
P = ks²
We have
s = 35
P = 1580
Then the value of k will be
1580 = (35)² × k
k = 1.2897
Then the equation will be
P = 1.2897s²
If the speed is 30 m per second. Then the power of the car engine will be
P = 1.2897 x 30²
P = 1160.8 watts

Find m∠RSQ
please and ty
Answer:
m∠RSQ = 19°
Step-by-step explanation:
From the picture attached,
RT is the diameter of the a circle.
Angle subtended at the circumference by the diameter of a circle = 90°
Therefore, m∠RST = 90°
Since, m∠RSQ + m∠QST = m∠RST
m∠RSQ + 71° = 90°
m∠RSQ = 90° - 71°
= 19°
Therefore, measure of angle RSQ is 19°.

What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values
What is the quadrant?A quadrant is defined as an area contained by the x and y axes, which there are four quadrants in a graph.
For Quadrant I : the value of x and y both are positive ( +,+ )
For Quadrant II : the value of x is negative and y is positive ( -,+ )
For Quadrant III : the value of x is negative and y is negative ( -, - )
For Quadrant IV : the value of x is positive and y is negative ( +, - )
Locate the quadrant of the angle.
If the angle is greater than 360°,
Subtract 360° until the angle is less than 360°.
⇒ 694 - 360
⇒ 334°
Hence, angle 694° lies Quadrant IV
