## Best TASC Math Prep Resource for 2020

1- 25.5
$$3x-5=8.5→3x=8.5+5=13.5→x=\frac{13.5}{3}=4.5$$
Then; $$5x+3=5 (4.5)+3=22.5+3=25.5$$

2- 8
First draw an isosceles triangle. Remember that two sides of the triangle are equal. Let put a for the legs. Then:
$$a=4⇒$$ area of the triangle is $$=\frac{1}{2} (4×4)=\frac{16}{2}=8$$
$$\img{https://appmanager.effortlessmath.com/public/images/questions/dtawyy4wy5.png }$$

3- 78
The perimeter of the trapezoid is $$50$$.
Therefore, the missing side (height) is $$= 50-18-12-14 =6$$
Area of a trapezoid:
A $$= \frac{1}{2} h (b_{1}+b_{2}) = \frac{1}{2} (6) (12+14) =78$$

4- 125
The question is this: $$1.75$$ is what percent of $$1.40$$? Use percent formula:
part$$=\frac{percent}{100}×$$whole$$⇒1.75=\frac{percent}{100}×1.40 ⇒ 1.75=\frac{percent ×1.40}{100} ⇒175=$$percent$$×1.40 ⇒$$ percent $$= \frac{175}{1.40} = 125$$

5- 2
Use PEMDAS (order of operation):
$$-18+6×(-5)-[4+22×(-4)]÷2+8=-18-30-[4-88]÷2+8=-48-[-84]÷2+8=-48+84÷2+8=-48+42+8=2$$

6- 60
The relationship among all sides of special right triangle
$$30^\circ-60^\circ-90^\circ$$ is provided in this triangle:
In this triangle, the opposite side of $$30^\circ$$ angle is half of the hypotenuse.
Draw the shape for this question:
The latter is the hypotenuse. Therefore, the latter is $$60$$ ft.

7- 3
Let $$x$$ be the length of an edge of cube, then the volume of a cube is: $$V=x^3$$
The surface area of cube is: $$SA=6x^2$$
The volume of cube A is $$\frac{1}{2}$$ of its surface area. Then: $$x^3=\frac{6x^2}{2}→x^3=3x^2$$, divide both side of the equation by $$x^2$$. Then: $$\frac{x^3}{x^2} =\frac{3x^2}{x^2} →x=3$$

8- 10
The input value is $$5$$. Then: $$x=5, f(x)=x^2-3x→ f(5)=5^2-3(5)=25-15=10$$

9- 33
Since $$N=6$$, substitute $$6$$ for N in the equation $$\frac{x-3}{5}=N$$, which gives $$\frac{x-3}{5}=6$$. Multiplying both sides of $$\frac{x-3}{5}=6$$ by $$5$$ gives $$x-3=30$$ and then adding $$3$$ to both sides of $$x-3=30$$ then, $$x=33$$.

10- 0.1
Write the ratio of $$5a$$ to $$2b. \frac{5a}{2b}=\frac{1}{4}$$. Use cross multiplication and then simplify. $$5a×4=2b×1→20a=2b→a=\frac{2b}{20}=\frac{b}{10}$$. Now, find the ratio of a to $$b$$. $$\frac{a}{b}=\frac{\frac{b}{10}}{b}→\frac{b}{10}÷b=\frac{b}{10}×\frac{1}{b}=\frac{b}{10b}=\frac{1}{10}=0.1$$

11- 20
The rate of construction company$$=\frac{30 \ cm}{1 \ min}=30 \ \frac{cm}{min }$$
Height of the wall after $$50$$ minutes $$= \frac{30 \ cm}{1 \ min}×50$$ min$$=1,500$$ cm
Let $$x$$ be the height of wall, then $$\frac{3}{4} x=1,500$$ cm $$→x=\frac{4×1,500}{3}→x=2,000$$ cm$$=20$$ m

12- 32
average$$=\frac{sum \ of \ terms}{number \ of \ terms}⇒ 20=\frac{13+15+20+x}{4}⇒80=48+x⇒x=32$$

13- B
$$α=180^\circ-112^\circ=68^\circ$$
$$β=180^\circ-135^\circ=45^\circ$$
$$x+α+β=180^\circ→x=180^\circ-68^\circ-45^\circ=67^\circ$$
$$\img{https://appmanager.effortlessmath.com/public/images/questions/ertw43.png }$$

14- A
Simplify and combine like terms.
$$(8x^3-8x^2+2x^4 )-(4x^2-2x^4+2x^3 ) ⇒ (8x^3-8x^2+2x^4 )-4x^2+2x^4-2x^3⇒$$
$$4x^4+6x^3-12x^2$$

15- C
The population is increased by $$15\%$$ and $$20\%. 15\%$$increase changes the population to $$115\%$$ of original population. For the second increase, multiply the result by $$120\%$$.
$$(1.15)×(1.20)=1.38=138\%$$. $$38$$ percent of the population is increased after two years.

16- D
Solve for $$x$$.
$$-2≤2x-4<8 ⇒$$ (add $$4$$ all sides) $$-2+4≤2x-4+4<8+4 ⇒$$
$$2≤2x<12 ⇒$$ (divide all sides by $$2) 1≤x<6, x$$ is between $$1$$ and $$6$$. Choice D represent this inequality.

17- D
Volume of a box$$=$$length$$×$$width$$×$$height$$=4×5×6=120$$

18- C
To find the number of possible outfit combinations, multiply number of options for each factor: $$6×5×4=120$$

19- A
In the stadium the ratio of home fans to visiting fans in a crowd is $$5:7$$. Therefore, total number of fans must be divisible by $$12: 5+7 =12$$.
Let’s review the choices:
A. $$12,324: 12,324÷12=1,027$$
B. $$42,326 : 42,326÷12=3,527.166$$
C. $$44,566 : 44,566÷12=3,713.833$$
D. $$66,812 : 66,812÷12=5,567.666$$
Only choice A when divided by $$12$$ results a whole number.

20- C
Three times of $$24,000$$ is $$72,000$$. One sixth of them cancelled their tickets. One sixth of $$72,000$$ equals $$12,000 (\frac{1}{6} ×72000 =12000). 60,000(72,000-12,000=60,000)$$ fans are attending this week.
