Augusto wants to prove to his parents that watching TV while he does his homework will help him get better grades. He decides to ask 20 of his friends if they watch TV while they do their homework and what their grades are. He finds that his friends who have high grades also watch TV while they do their homework. He tells his parents that he has proven that watching TV while doing homework will cause his grades to improve. What mistake has Augusto made?

It is rational.

√1/4 = 1/4

Answer:

8

Step-by-step explanation:

You just need to multiply 20 by 2/5

Or, multiply 20 by 2, then divide by 5.

20 x 2/5

40/5

8

2/5 of 20 = 40/5 or simply, 8.

Have a great day!

Answer:

A = 372 units²

Step-by-step explanation:

The area (A) of a trapezium is calculated as

A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )

where h is the perpendicular height and b₁, b₂ the parallel bases

Here h = 24 , b₁ = 24, b₂ = 7 , then

A = [tex]\frac{1}{2}[/tex] × 24 × (24 + 7) = 12 × 31 = 372 units²

Answer:

C (95 people)

Step-by-step explanation:

380 is basically like 100% so 380÷100= 3.8 (which is equal to 1%), then use a calculator to do 3.8x25=95 (this makes 25%)

Answer:

C.95

Step-by-step explanation:

25/100=0.25

380*0.25=95

Answer:

25/24    or    1 and 1/24

Step-by-step explanation:

2/3 + 3/8 = 16/24 + 9/24 = 25/24 or 1 1/24

Answer:

[tex]\boxed {\boxed {\sf x=0}}[/tex]

Step-by-step explanation:

To solve this equation, we must isolate the variable (x) using inverse operations.

[tex]-3(x-2)=6[/tex]

x-2 is being multiplied by -3. The inverse operation of multiplication is division, so we divide both sides by -3.

[tex]-3(x-2)/-3= 6/-3\\(x-2)=6 /-3 \\(x-2)= -2[/tex]

2 is being subtracted from x. The inverse operation of subtraction is addition, so add 2 to both sides of the equation.

[tex]x-2+2=-2+2\\x=-2+2\\x=0[/tex]

In this equation, x is equal to 0.

Answer:

Assuming that [tex] \overline{AOC} [/tex] is a diameter.

Given that [tex] m\angle{BAC} \: = \: 66° [/tex]

And that point O is the center of the circle

[tex] \boxed{m\angle{BAC} \: = \: 57°} [/tex]

Explanation:

Because angle AOB is subtended by arc AB from point O.

Arc AB is equal to the measure of that angle.

Since arc ABC is subtended by the diameter, the arc is 180°.

You have 2 shapes, a rectangle and a half circle.

Area of rectangle = 3 x 8 = 24

Area of a half circle = 1/2 x pi x r^2

Area of half circle = 1/2 x 3.14 x 4^2

Area of half circle = 25.12

Total area = 24 + 25.12 = 49.12 square units

Answer:

(-2,7)

x= -2

y= 7

Step-by-step explanation:

We have

x-3y= -23

5x+2y=4

Let's solve this through substitution

let's start by adding 3y in the first equation

x= -23 +3y

plug this into the second one

5(-23+3y)+2y=4

-115+15y+2y=4

17y=119

y=7

Plug this y value into our first equation

x-3(7)= -23

x-21= -23

x= -2

Given:

The square base pyramid with height 3 cm and base edge 2 cm.

To find:

The volume of the square pyramid.

Solution:

Volume of a square base pyramid is:

[tex]V=\dfrac{1}{3}Bh[/tex]            ...(i)

Where, B is the base area and h is the height of the pyramid.

Base is a square with edge 2 cm, so the base area is:

[tex]B=a\times a[/tex]

Where, a is the edge of the square base.

[tex]B=2\times 2[/tex]

[tex]B=4[/tex]

Putting [tex]B=4,h=3[/tex] in (i), we get

[tex]V=\dfrac{1}{3}(4)(3)[/tex]

[tex]V=4[/tex]

Therefore, the volume of the given pyramid is 4 cm³.

Answer:

C) 14/4

Step-by-step explanation:

Multiply the amount of land per month by the number of months.

(2/4)(7) = 14/4 acres

Option C is correct, 14/4  acres of land does the business plant with trees after the 7 months

A fraction represents a part of a whole.

A business plants trees on 2/4 acre of land each month for 7 months.

We have to find the number of acres of land does the business plant with trees after the 7 months

To find this we have to multiply seven with two by four

7×2/4

14/4

Hence, 14/4  acres of land does the business plant with trees after the 7 months
