The mean average of 4 numbers is 88 what is the fourth number if three of the numbers are 80 95 and 85?

Answers

Answer 1

Answer:the fourth number is =97

Step-by-step explanation:

Mean = total number of the given numbers( x1 +x2+ x3....) /  numbers given

Let the fourth number be x

given that the mean of 4 numbers = 88 and only 3 numbers are given

such that

Mean = total number of the given numbers( x1 +x2+ x3....) /  numbers given becomes

88=  (80 +90 + 85 + x ) / 4

88 x 4 =80 +90 + 85 + x

352=255+x

x= 352-255

x=97

A middle school student reads 48 books in 31/3 years. Find the students reading rate in books per year

Answers

Answer: 14 2/5 books per year

Step-by-step explanation:

From the question, we are informed that a middle school student reads 48 books in 31/3 years. The students reading rate in books per year will be calculated as:

= Total books read / Number of years

= 48 ÷ 3 1/3

= 48 ÷ 10/3

= 48 × 3/10

= 144/10

= 14 2/5 books per year

Factor.

1.) Triangle ABC is congruent to triangle DCB

Step-by-step explanation:

For the first one, the first 3 steps proved that all 3 sides in the 2 triangles formed by the diagonal are congruent to each other, meaning triangle ABC is congruent to triangle DCB (I named it like that specifically because the way you name the triangles has to be the exact same way you named the other triangle).

For the second one, the congruency statement should be GL ≅ AD, because the HL congruence theorem states that if a hypotenuse and leg of one right triangle is congruent to the hypotenuse and leg of another right triangle, those triangles are congruent.

Two more than 11 times a number is equal to 24. What is the number?

Answers

Answer:

2

Step-by-step explanation:

Brainliest?!?!?!?

The answer to this would be 2.

Step by Step Explanation

Equation: 11x+2=24

Variable for the missing number: x

To do this, I suggest writing out an equation with the variable X to represent the missing number that we are trying to find. The equation would look something like this: 11x+2=24.

From here, to solve the equation, subtract 2 from both sides, which would then get the equation to be 11x=22. From here, you would then divide both sides by 11 to get the variable on it's own, which would be x=2. Since x is the variable that we are using to represent the missing number, the missing number would be 2.

A rectangle has length of 80cm and a width 50cm. And a scale factor of 3.5 what is the area in square cm of the dilated rectangle

Answers

Answer:

49,000 square cm

Step-by-step explanation:

To get the area of the dilated rectangle, we need the dilated dimensions

We simply multiply the scale factor by the dimensions

we have this as;

3.5 * 50 = 175 cm

and

3.5 * 80 = 280 cm

The area of the dilated rectangle is thus;

280 * 175 = 49,000 cm^2

Tickets for the karaoke talent show sponsored by the Speech Club were priced at $3 for adults and $2 for students. The club treasurer counted 300 tickets sold for a total of $650. Write and solve a system of equations to determine how many adult and student tickets were sold.

Answers

Answer:

50 adults and 250 students tickets were sold

Step-by-step explanation:

Given data

Let the number of adults be x and students be y

3x+2y=650------1

x+y= 300---------2

from 2

x= 300-y

put the value of x in 1

3(300-y)+2y= 650

900-3y+2y= 650

900-y= 650

900-650= y

y=250

put the value of y in 2

x+250= 300

x= 300-250

x= 50

Hence 50 adults and 250 students tickets were sold
