Answer: $135
Step-by-step explanation: x(40/100)=54. x represents the original price and 40/100 is the discount while 54 is the money saved from the discount. This ultimately shows us 40% of something is 54 and that something is represented by x and x equals 135.

Answer:
2/3 ft
Step-by-step explanation:
area of triangle =base*height/2
2/5=base*6/5/2
2/5 *2 =base * 6/5
4/5 =base*6/5
4/5÷6/5=base
4/5 * 5/6=base
20/30=base
2/3=base
therefore base=2/3 ft
Bruce wants to make 50 ml of an alcohol solution with a 12% concentration. He has a 10% alcohol solution and a 15% alcohol solution. The equation 0.10x + 0.15(50 – x) = 0.12(50) can be used to find the amount of 10% alcohol solution Bruce should use.
How much of the 10% alcohol solution should Bruce use?
How much of the 15% alcohol solution should Bruce use?
Answer:
10% = 30 15% = 20

Given the triangle below, what is the measure of x to the nearest foot?
Answer:
18 ft
Step-by-step explanation:
Since the triangle is right angled ; we could use trigonometry ;
Using the angle , 40° ; adjacent side, = 14 feets ; hypotenus = x
Cos θ = Adjacent / hypotenus
Cos 40 = 14 / x
0.7660444 = 14 / x
0.7660444x = 14
x = 14 / 0.7660444
x = 18.27
= 18 ( nearest foot)

The equation of a circle is x2 + y2 + 2x - 10y - 38 = 0. What are the coordinates of the
center and the length of the radius of the circle?
Answer:
Centre = (-1, 5)
radius = 8units
Explanation
The standard form of the equation of a circle is expressed as
x^2+y^2+2gx+2fy+C = 0
Center = (-g, -f)
radius = √g²+f²-C
Given the equation of a circle is x² + y²+ 2x - 10y - 38 = 0.
On comparing
2gx = 2x
2g = 2
g = 2/2
g = 1
2fy = -10y
2f =-10
f =-5
Centre = (-1, -(-5)) = (-1, 5)
radius = √1²+5²-(-38)
radius = √1+25+38
radius = √64
radius = 8units

Explanation:
By definition the perimeter of an object is the length of all its sides.
Also by definition, for a rectangle the 2 sides of the width are equal and the 2 sides of the length are equal.
Therefore the equation for the perimeter of a rectangle can be written as:
p

where
p

l
is the length and

Answer:
11 in
Step-by-step explanation:
The area of a square is given by
A = s^2 where s is the side length
121 = s^2
Taking the square root of each side
sqrt(121) = sqrt(s^2)
11= s
Answer:
The side of square is 11 m.
Step-by-step explanation:
To calculate the side of square .
Here, given area of square which is 121 inches².
Using Formula :-
Area of square = ( side )²where, side is the length of side of square.
Solution :-
Area of square = ( side )²
121 inches² = side²
Taking square root of both side
√121 inches² = √side²
11 inche = side
Hence, The side of square is 11 inche.

pls help me with this maths equation
Answer:
Step-by-step explanation:
given :
y = 120 degree
z = 57 degree
angle x = ?
first lets find angle c in triangle BDC
angle c + z = y (sum of two interior opposite angle is equal to the exterior angle formed)angle C + 57 = 120
angle C = 120 -57
angle C = 63 degree
Now lets find angle B in triangle BDC
angle B + angle C + z = 180 degree (sum of interior angles of a triangle)
angle B + 63 + 57 = 180
angle B + 120 = 180
angle B = 180 - 120
angle B = 60 degree
now for angle x
angle B + z = angle x (sum of two interior opposite angles is equal to the exterior angle formed)
60 + 57 = x
117 = x

The volume of a cuboid is 462cm3. The length is 11cm and the width is 60mm. Work out the height of the cuboid
Answer:
step-by-step explanation: 1cm is equal to 10mm
The volume of a cuboid is length ×breadth×height
We start by converting 60 mm into cm which will be 6cm
Solution :
462cm3=11cm×6cm
462cm3/66=66cm/66
The final answer will be 7cm
Therefore the height is 7cm
In base 2, what is the value of 1011₂ + 10111₂
1011₂ + 10111₂
= (1000₂ + 10₂ + 1₂) + (10000₂ + 100₂ + 10₂ + 1₂)
= 10000₂ + 1000₂ + 100₂ + 2 (10₂) + 2 (1₂)
= 10000₂ + 1000₂ + 100₂ + 2 (10₂) + 10₂
= 10000₂ + 1000₂ + 100₂ + 100₂ + 10₂
= 10000₂ + 1000₂ + 2 (100₂) + 10₂
= 10000₂ + 1000₂ + 1000₂ + 10₂
= 10000₂ + 2 (1000₂) + 10₂
= 10000₂ + 10000₂ + 10₂
= 2 (10000₂) + 10₂
= 100000₂ + 10₂
= 100010₂
Huxian's father gives her $120 as her monthly allowance. a) If she spends an average of 5 dollars a day, find the amount on money that she is left with after 1) 3 days 2) 6 days 3) 10 days
Answer:
3 days= $105, 6 days= $90, 10 days= $70
Step-by-step explanation:
You can rewrite this equation as y=120-5x
x is the amount of days passed
plug in 3 for x and you get 15. 120-15=105
plug in 6 for x and you get 30. 120-30=90
plug in 10 for x you get 50. 120-50=70
Hope this helps!

Which equation could be used to find x in AABC? *
A
10
320
B
Answer:
Step-by-step explanation:
x is the length of the side opposite the reference angle of 32, and 10 is the side length adjacent to the reference angle. This satisfies the tangent ratio where
[tex]tan32=\frac{x}{10}[/tex] and solving for x:
x = 10tan32

Bob and Carl each rented the same kind of moving truck from EZ Move. There was a flat rental fee plus a charge per mile that the truck was driven. Bob’s cost for his truck was $112.96 for 138 miles. Carl’s cost for his truck was $142.78 for 209 miles. Which equation can be used to represent the cost of the rental truck?
Round to the nearest hundredth if necessary.
Answer:
ok so we can turn both of these into equations
Bob: 112.96 divided by 138=0.81855072463
so about 82 cents per mile
Carl: 142.78 divided by 209=0.68315789473
so about 68 cents per mile
