The price of a new car was £11 800
It is reduced to £10 384
Work out the percentage reduction.
Answer:
12 % reduction
Step-by-step explanation:
11800 - 10384 = 1416
1416 / 11800 = 0.12
0.12 × 100 = 12
The sum of two numbers is 88. The difference of those same two numbers is 60. Which answer choice
shows both numbers?
Step-by-step explanation:
Let the 2 numbers be X and Y
X+Y=88
X-Y=60
______
2X. = 148. X=74
Put the value of X to find Y
74+Y=88
74-Y = 60 :. Y = 14
=>X=74
=>Y=14

two families go to the zoo
the smith family of two adults and three children pay £61
the jones family of three adults and five children pay £96
how much is one adult ticket and how much is one childrens ticket
Answer:
So adult tickets cost £17.00 and child tickets cost £9.00
Step-by-step explanation:
2a+3c=61
2a=61-3c
a=30.5-1.5c
...
3a+5c=96, using a found above we get:
3(30.5-1.5c)+5c=96
91.5-4.5c+5c=96
91.5+0.5c=96
0.5c=4.5
c=9, and since a=30.5-1.5c
a=17
So adult tickets cost £17.00 and child tickets cost £9.00
Answer:
The adult tickets cost £17.00 and child tickets cost £9.00
Step-by-step explanation:
2a + 3c = 61
2a = 61 - 3c
a = 30.5 - 1.5c
3(30.5 - 1.5c) + 5c = 96
91.5 - 4.5c + 5c = 96
91.5 + 0.5c = 96
0.5c = 4.5
c = 9
a = 30.5 - 1.5c
a = 17
The adult tickets cost £17.00 and child tickets cost £9.00

Write the equation of the line in fully simplified slope-intercept form.
Answer:
y = -x + 2
Step-by-step explanation:
[slope-intercept form] y = mx + b
m [slope] = ∆y/∆x = y₂–y₁ / x₂–x₁
b [y-intercept] = (0,b) → x = 0.
If y = 2 when x = 0, b = 2.
Since y decreases by 1 unit everytime x increases by 1 unit
a decrease by 1 unit is represented by -1, and an increase of 1 is represented by 1.
So a decrease of -1 over an increase of 1
is -1/1 = -1 = m.

To answer this, find the area of each side, then add the values together.
Normally Surface Area = 2 (wl + hl + hw) but in this case, the easiest way to solve this is to divide the shape into 2 different rectangular prisms. Your new equation would be: SA = Sa₁ + Sa₂ or it could be
SA = [2 (wl + hl + hw)] + [2 (wl + hl + hw)]
We'll start by solving the surface area for the larger rectangular prism.
Sa₁ = 2 (wl + hl + hw) substitute w, l, and h
Sa₁ = 2 [(10)(0.5) + (12)(0.5) + (12)(10)]
Sa₁ = 2 (131)
Sa₁ = 262
Now do the same equation for the smaller rectangular prism
Sa₂ = 2 (wl + hl + hw) substitute w, l, and h
Sa₂ = 2 [(10)(0.5) + (4)(0.5) + (4)(10)]
Sa₂ = 2 (47)
Sa₂ = 94
Now add Sa₁ and Sa₂
SA = 262 + 94
SA = 356

What is the least common denominator (LCD) of 12 and 23?
5
6
12
18
Answer: none of those, 276...?
Step-by-step explanation:
You need to know the least common denominator (LCD) of 12 and 23 if you want to add or subtract two fractions with 12 and 23 as denominators.
The least common denominator, also called lowest common denominator (LCD), of 12 and 23 is 276.
Here is a math problem example where you need to know the LCD of 12 and 23 to solve:
3/12 + 2/23 = ?
Step 1) Take the LCD and divide each denominator by it as follows:
276/12 = 23
276/23 = 12
Step 2) Multiply each nominator with the respective answers from Step 1:
3 x 23 = 69
2 x 12 = 24
Step 3) Put it all together to solve the problem:
69/276 + 24/276 = 93/276
= 3/12 + 2/23 = 93/276
It's that easy! Once again, the lowest common denominator (LCD) of 12 and 23 is as follows:
276

Find the value of x.
#9,10,11,&12
Answer:
Step-by-step explanation:
9). It's given in the triangle → Two angles are equal in measure
Therefore, by the definition of an isosceles triangle, opposite sides of the equal angles are equal in measure.
x = 12
10). Two sides of the given triangles are equal in length.
By the definition of an isosceles triangle, opposite angles of the equal sides of the triangle will be equal in measure.
Therefore, y = 55°
By the triangle sum theorem,
x° + y° + 55° = 180°
x° + 55° + 55° = 180°
x = 180 - 110
x = 70°
11). By the definition of an isosceles triangle, opposite sides of the equal angles will be equal in measure.
x + 3 = 12
x = 9
12). By the definition of an isosceles triangle, opposite angles of the equal sides of the triangle will be equal in measure.
m∠2 = 53°
x + 65 = 53
x = 53 - 65
x = -12
find the value of x in each of the given triangles.

Statement 4 in true.
Step-by-step explanation:
1. f(-2)=(-3*(-2)+2)^2+(-2)=(6+2)^2+(-2)=8^2-2=62, FALSE
2. f(-5)=(-3*(-5)+2)^2+(-5)=(15+2)^2+(-5)=17^2+(-5)=289-5=284, FALSE
3. f(3)=(-3*3+2)^2+3=(-9+2)^2+3=(-7)^2+3=49+3=52, FALSE
4. f(5)=(-3*5+2)^2+5=(-15+2)^2+5=(-13)^2+5=169+5=174, TRUE
Answer:
option 4
Step-by-step explanation:
f(- 2) = (6 + 2)² - 2 = 8² - 2 = 64-2 = 62 ≠ 64
f(- 5) = (15 + 2)² - 5 = 17² - 5 = 289 - 5 = 284 ≠ 29
f(3) = (- 9 + 2)² + 3 = (- 7)² + 3 = 49 + 3 = 52 ≠ - 11
f(5) = (- 15 + 2)² + 5 = (- 13)² + 5 = 169 + 5 = 174 ← True

Read the passage from an online source.
Aqueducts were amazing feats of engineering given the time period. Though earlier civilizations in Egypt and India also built aqueducts, the Romans improved on the structure and built an extensive and complex network across their territories. . . .
Aqueducts required a great deal of planning. They were made from a series of pipes, tunnels, canals, and bridges. Gravity and the natural slope of the land allowed aqueducts to channel water from a freshwater source, such as a lake or spring, to a city.
–"Roman Aqueducts,”
National Geographic
Which piece of evidence from the passage best supports the claim that Romans developed advanced technology that influenced modern society?
The Romans were very smart.
The Romans had many lakes and springs.

An airplane travels at 120 km/hr for 2 hours in a direction of 260° . At the end of this time, how far south.Of the airport is the airplane
Answer:
the airplane is 130.56 km south of the airport after 2 hours
Step-by-step explanation:
given data
travel speed = 120
time travel = 2 hour
direction = 260°
solution
we get here direst distance covered by plane in 2 hours that is
distance cover = 120 × 2
distance cover = 240 kilometers
and
the south component of the distance will be here as
distance = 240 × sin(270 - 260) = - 130.56
so the airplane is 130.56 km south of the airport after 2 hours
