Answer:
Ahmed:
x + 6y = 360
Sarah:
3x + 6y = 420
Step-by-step explanation:
Let
Cost of the small box = x
Cost of the medium box = y
Ahmed:
x + 6y = 360
Sarah:
3x + 6y = 420
x + 6y = 360 (1)
3x + 6y = 420 (2)
Eliminate y by subtracting (1) from (2)
3x - x + 6y - 6y = 420 - 360
2x = 60
x = 60/2
x = 30
Substitute x = 30 into (1) to find y
x + 6y = 360
30 + 6y = 360
6y = 360 - 30
6y = 330
y = 330/6
y = 55
Cost of the small box = x = 30 dirhams
Cost of the medium box = y = 55 dirhams

Answer:
75 feet
Step-by-step explanation:
the shadow to the object would be a 4:5 ratio
since the shadow of the flagpole is 60 ft,
4x=60 so x would =15

A coach buys a uniform and a basketball for each of the 20 players on the team. Each
basketball costs $10.40. The coach spends a total of $620 for uniforms and basketballs
What was the cost of a single uniform?
Answer:
$20.60
Step-by-step explanation:
You find how much it costs for the total amount of basketballs (10.40×20=208), then you subtract that number from the total cost of everything to get the cost of all the uniforms (620-208=412), then you divide the total costs for all uniforms by 20 to find the cost for a single uniform (412÷20=20.6). Always make sure that the decimals go until the hundredths place for USD.
Hope this helps!

A car dealership has 180 cars on their lot. If they increase their inventory be 25%, how many cars will be on the lot?
25/100 * 180
= 5 * 9 = 45
Therefore:
180 + 45 = 225 cars
Answer:
There will be 225 cars on the lot.

SOCCER PRACTICE BEGAN AT 2:30 P.M 3:30 P.M THROUGH WHAT FRACTION OF A CIRCLE DID THE MINUTE HAND TURN HOW MANY DEGREES DID THE MINUTE HAND TURN
Answer:
1 /1 ; 360°
Step-by-step explanation:
Start time = 2:30 pm
Stop time = 3:30 pm
Minute hand makes a complete revolution per hour ;
This means that the minutes hand revolves round the whole circle in one hour, hence fraction of the circle covered by the minute hand between 2:30 pm - 3:30 pm is 1/1 = 1
The angle turned by the minutes hand :
1 complete revolution = 360°
A circle covers 360°
1 /1 fraction of a circle = 1/1 * 360° = 360°
Hence, angle turned by the minute hand = 360°

A rectangle has a length of 2x + 1 and a width
of 5x - 4. Which expression best describes the
area of the rectangle?
F 7x - 3
H 10x2 – 3x - 4
J 10x2 + 13x - 4
G 14x - 6
Answer:
H
Step-by-step explanation:
The rectangle has a length of (2x + 1) and a width of (5x - 4).
And we want to select the expression that represents the rectangle's area.
Recall that a rectangle's area is simply its length multiplied by its width. Thus:
[tex]A=(2x+1)(5x-4)[/tex]
Expand by distributing:
[tex]A=(2x+1)(5x)+(2x+1)(-4)[/tex]
Distribute:
[tex]A=(10x^2+5x)+(-8x-4)[/tex]
Simplify:
[tex]A=10x^2-3x-4[/tex]
Hence, our answer is H.

Find the value of the variables in the simplest form
Answer:
x = 2
Step-by-step explanation:
Using Pythagoras' identity in the right triangle
x² + x² = (2[tex]\sqrt{2}[/tex] )² , that is
2x² = 8 ( divide both sides by 2 )
x² = 4 ( take the square root of both sides )
x = [tex]\sqrt{4}[/tex] = 2

Fred kicks a ball with a force of 20n to George, who is 5m away. How much work was done to the ball
Answer:
100 Nm
Step-by-step explanation:
Work is said to be done when a force moves a body through a distance. This may be expressed as
work done = Force * distance
where
work done is measured in joules or Newton-meter
Force is measured in newtons and distance in meters
Substituting the given values,
Workdone = 20 * 5
= 100 Nm
= 100J

Triangle Sums***GRADED 1 of 51 of 5 Items #1 Triangle RST is shown. What is the measure of ∠T? Record your answer and fill in the bubbles on the grid. Be sure to use correct place value.
Answer:
[tex]\angle T = 70[/tex]
Step-by-step explanation:
Given
[tex]\angle T= 2x[/tex]
[tex]\angle S= 75[/tex]
[tex]\angle R= x[/tex]
See attachment for triangle
Required
Calculate [tex]\angle T[/tex]
First, we add up the angles in the triangle;
[tex]\angle R + \angle S + \angle T = 180[/tex]
[tex]x + 75 + 2x = 180[/tex]
Collect like terms
[tex]x + 2x = 180 - 75[/tex]
[tex]3x = 105[/tex]
Solve for x
[tex]x = \frac{105}{3}[/tex]
[tex]x = 35[/tex]
Given that:
[tex]\angle T= 2x[/tex]
[tex]\angle T = 2 * 35[/tex]
[tex]\angle T = 70[/tex]
