The percentage of student answered correctly is 87.5%.

A percentage, a relative value indicating hundredth parts of any quantity.

The following formula is a common strategy to calculate a percentage:

According to the given question.

Total number of questions = 48

Total number of questions which are answered correclty by a student = 42

Therefore, the percentage of question the students answered correctly is given by

[tex]Percentage = \frac{total \ correctly \ answered\ questions}{Toal\ number \ of\ questions\ } \times 100[/tex]

[tex]\implies percentage = \frac{42}{48} \times 100[/tex]

[tex]\implies percentage = 0.875\times 100[/tex]

[tex]\implies percentage = 87.5\%[/tex]

Hence, the percentage of student answered correctly is 87.5%.

Step-by-step explanation:

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:

D, the volume of the rectangular prism is 36 cm

Step-by-step explanation:

2 x 3 x 6 = 36

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:

[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.

It is rational.

√1/4 = 1/4

Given:

The total revenue of this year = $14,600

This year revenue is 27% less than their total revenue in the previous year.

To find:

The total revenue in the previous year.

Solution:

Let x be the total revenue of the previous year.

This year revenue is 27% less than their total revenue the previous year.

Revenue in this year = Revenue in previous year - 27% of it

[tex]14600=x-\dfrac{27}{100}x[/tex]

[tex]14600=x-0.27x[/tex]

[tex]14600=0.73x[/tex]

Divide both sides by 0.73.

[tex]\dfrac{14600}{0.73}=x[/tex]

[tex]20,000=x[/tex]

Therefore, the total revenue in the previous year is $20,000.

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

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
