Answer: Choice D
Round 55 percent to 50 percent and 64 to 60. Think of 50 percent as 1/2 so 1/2 of 60 is 30.
===================================================
Explanation:
There are many ways to estimate, but this is probably the easiest since 1/2 = 0.50 = 50%, and taking half of something is fairly straightforward and quick.
Taking half of 60 is like taking half of 6, except we stick at 0 at the end.
Half of 6 is 3
Half of 60 is 30
The estimate of 55% of 64 is 30
The actual value is
55% of 64 = 0.55*64 = 35.2
which isn't too far off.
-------------------------
Extra info:
Choice A is false because 40% is not equal to 1/4. Instead 1/4 = 0.25 = 25%Choice B is false because 1/3 = 0.333 = 33.3% approximately, so 1/3 is not equal to 60%Choice C is false because 1/5 = 0.20 = 20% and not 50%1.8 -0.4y = 2(1.1 - Y)
Answer:
y=0.25
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1.8−0.4y=2(1.1−y)
1.8+−0.4y=(2)(1.1)+(2)(−y)(Distribute)
1.8+−0.4y=2.2+−2y
−0.4y+1.8=−2y+2.2
Step 2: Add 2y to both sides.
−0.4y+1.8+2y=−2y+2.2+2y
1.6y+1.8=2.2
Step 3: Subtract 1.8 from both sides.
1.6y+1.8−1.8=2.2−1.8
1.6y=0.4
Step 4: Divide both sides by 1.6.
1.6y/1.6 = 0.4/1.6

Determine if the function is linear. if it is, find the rate of change
Given that f(x) = x2 – 3x - 10 and g(x) = x – 5, find (f - g)(x) and express
the result in standard form.
Answer:
[tex](f-g)(x)= x^2-4x-5[/tex]
Step-by-step explanation:
We have the two functions:
[tex]f(x)=x^2-3x-10\text{ and } g(x)=x-5[/tex]
And we want to find (f-g)(x).
(f-g)(x) is equivalent to f(x)-g(x).
Therefore:
[tex]\begin{aligned} (f-g)(x)&=f(x)-g(x)\\ &=(x^2-3x-10)-(x-5)\end{aligned}[/tex]
Simplify:
[tex]\begin{aligned} &=x^2-3x-10-x+5 \\ &=(x^2)+(-3x-x)+(-10+5) \\ &=x^2-4x-5\end{aligned}[/tex]
Therefore:
[tex](f-g)(x)= x^2-4x-5[/tex]
Answer:
x^2 -3x+5 = 0

5) It is known that ∠BAM and ∠CTX are complementary. If m∠BAM = x + 2 4 and m∠CTX = x + 11, then
solve for the value of x algebraically.
Answer:
x = [tex]27.5^{o}[/tex]
Step-by-step explanation:
complementary angles are two or more angles whose sum is equal to [tex]90^{o}[/tex].
Thus given that;
m<BAM = x + 24
m<CTX = x + 11
So that,
m<BAM + m<CTX = 90
⇒ (x + 24) + (x + 11) = 90
x + 24 + x + 11 = 90
2x + 35 = 90
2x = 90 - 35
2x = 55
x = [tex]\frac{55}{2}[/tex]
= 27.5
The value of x is [tex]27.5^{o}[/tex].
So that,
m<BAM = x + 24
= 27.5 +24
= [tex]51.5^{o}[/tex]
m<CTX = x + 11
= 27.5 + 11
= [tex]38.5^{o}[/tex]
Answer:
x = 25
Step-by-step explanation:
combine like terms ans then solve for x

8. Mohan wants to buy a trapezium shaped field.
Its side along the river is parallel to and twice
the side along the road. If the area of this field is
10500 m² and the perpendicular distance
between the two parallel sides is 100 m, find the
length of the side along the river.
Top surface of a raised platform is in the shape
ofthe octagonalourfa
Answer:
The length of the side along the river is 140 m
Step-by-step explanation:
Equations
To solve the problem, we need to recall the area of a trapezium is:
[tex]\displaystyle A=\frac{b1+b2}{2}.h[/tex]
Where b1 and b2 are the lengths of the parallel sides and h is the height of the trapezium.
The field to be bought by Mohan has a trapezium shape with a side along the road of side x and a side along the river of side 2x, as stated in the problem.
Knowing the height is h=100 m, and the area is 10500 m2:
[tex]\displaystyle \frac{x+2x}{2}\cdot 100=10500[/tex]
Simplifying:
[tex]\displaystyle (3x)\cdot 50=10500[/tex]
[tex]150x=10500[/tex]
Dividing by 150:
[tex]x = 10500 / 150 = 70[/tex]
x = 70 m
2x = 140 m
The length of the side along the river is 140 m

The teacher asked 4 students to measure 4 different objects. Here are the results
Which student had the greatest percent error?
Answer:
Student 3 had the greatest percentage error.
Step-by-step explanation:
Student 1
Actual length = 50in
Measured length = 49in
Error = 50 - 49 = 1
Error% = 1/50 × 100
= 1 × 2
= 2%
Student 2
Actual length = 100cm
Measured length = 110cm
Error = 100 - 110 = 10
Error% = 10/100 × 100
= 10 × 1
= 10%
Student 3
Actual length = 2cm
Measured length = 2.5cm
Error = 2 - 2.5 = 0.5
Error% = 0.5/2 × 100
= 0.5 × 50
= 25%
Student 4
Actual length = 10ft
Measured length = 9½ft
Error = 10 - 9½ = ½
Error% = ½/10 × 100
= ½ × 10
= 1 × 5
= 5%
