How do you get 60cm2 in question 1?
Answer:
Step-by-step explanation:
4*2=8, thats one rectangle (side)
8*2 is 16, thats TWO rectangles (sides)
7*4=28, thats one rectangle (front)
28*2=56, thats TWO rectangles (front and back)
7*2=14, thats one rectangle (top)
14*2=28, thats TWO rectangles (top and bottom)
add all of these surface areas together
TWO rectangles + TWO rectangles + TWO rectangles
28+56+16=100
As you can see, the 60cm2 is incorrect. 100cm2 is the real surface area of the shape

3. In the diagram below AB' is the image of AB after a reflection in AC. If mBAC4x7 and mBAB ' 64 , then which of the following is the value of x?
(1) 6.25 (3) 14.25 (2) 12.5 (4) 18.75
When a line or shape or point is reflected, it must be reflected over a line.
The value of x is (b) 14.25
Reflection is a rigid transformation;
This means that:
[tex]\mathbf{\angle AC = \angle AB}[/tex]
So, we have
[tex]\mathbf{4x + 7 = 64}[/tex]
Subtract 7 from both sides
[tex]\mathbf{4x = 57}[/tex]
Divide both sides by 4
[tex]\mathbf{x = 14.25}[/tex]
Hence, the value of x is (b) 14.25

(0,1),(5,6),(7,9)
Answer:
yes
Step-by-step explanation:
For every input (x) there is exactly one output (y).
Yes, the given relation is a function. Because, every single input is matching exactly one output.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
The given ordered pairs are (0,1), (5,6), (7,9).

Please help quick! Find the value of x to the nearest tenth.
Answer: 3.3
Step-by-step explanation: pythagorean theorem.
first we'll do the bottom triangle. a^2 + b^2 = c^2
a=3 and b=4
(3)^2 + (4)^2 = 9 + 16 = 25 which = c^2
to find c from c^2, square root the c^2 value. in this case it's 25. the square root of 25 is 5.
5 is now the base of the rectangle
now we can do pythagorean theorem again. except we'll switch it so it's c^2 - b^2 =a^2
c=6 and b=5
(6)^2 - (5)^2 = 36 - 25 = 11 = a^2
to find a we'll square root 11 which is just [tex]\sqrt{11[/tex]. approx. 3.3 to the nearest tenth.
We can use the Pythagorean theorem to solve for x.
But first, we have to find the value of 'a' (as I labelled in the diagram below). We could actually do all this in one step if we set it up correctly.
so x = √(6² - a²)
& a² = 3² + 4²
⇒ x = √[6² - (3² + 4²)]
x = √(11) or ≈ 3.3167

Write the sentence as an inequality -7/8 is at most the difference of twice a number m and 5/4
Answer:
2m - 5/4 ≤ -7/8
The given inequality can be written as 2m - 5/4 ≤ -7/8.
What is an inequality ?Inequality is of four types they are
a<b ⇒ a is less than b.
a≤b ⇒ a is less than or equal to b.
a>b ⇒ a is greater than b.
a≥b ⇒ a is greater than or equal to b.
According to the given question
An inequality -7/8 is at most the difference of twice a number m and 5/4 which is 2m - 5/4 ≤ -7/8.
Difference of twice a number 'm' and 5/4 is 2m - 5/4 and this is at most -7/8 means less than or equal to.
∴ The given statement can be written as 2m - 5/4 ≤ -7/8

Tim explained a function in words and Paul wrote an equation.
Tim
The amount of money in a savings account increases at a rate of $225 per month. After eight months, the bank account has $4,580 in it.
Paul
y−1,400=56(x+26)
Whose function has the smaller y-intercept?
Tim’s with a y-intercept of $2,700
Paul’s with a y-intercept of $2,856
Paul’s with a y-intercept of $2,800
Tim’s with a y-intercept of $2,780
Answer:
Tim's with a y-intercept of $2,780
Step-by-step explanation:
To find Paul's y-intercept, solve the equation y-1400=56(x+26) for y. Then use the standard format for a linear equation y=mx+b to determine the y-intercept which would be b.
Step 1. Get y by itself by adding 1,400 to both sides.
y-1400 + 1400 = y
56(x+26) + 1400 = 56(x+26) + 1400
New equation y = 56(x+26) + 1400
Step 2. Distribute 56(x+26)
56(x+26) = 56 * x + 56 * 26 = 56x + 1456
New equation y = 56x + 1456 + 1400
Step 3. Simplify.
y = 56x + 2856
Paul's y-intercept would be 2856 because when y=0 x=2856
To Find Tim's y-intercept, subtract 225 * 8 from 4580.
225 * 8 = 1800
4580 - 1800 = 2780

A cricket bat is bought for $400. Later, it is sold with a loss of 15%. How much is the cricket bat sold for? =
After selling the cricket bat, how much money has been lost? Give your answer to two decimal places because it is a currency.=
Answer:
$340.00
Step-by-step explanation:
What I like to do first is find 10% of the number.
So 10% of 400 would be $40.
Then find half (5%) of the 10% ($40), which would be $20.
Add the $40 + $20 to get $60.
Then take $400 and subtract $60,
which gives you $340.00
