Answer: I think 91.9

Step-by-step explanation:

If I remember right, all the angles of a triangle add up to 180 degrees. So taking 22.8 + 65.3 = 88.1, then 180 - 88.1 = 91.9

Sorry if that’s not right! I just wanted to take a crack at it.

Answer:

91.9

Step-by-step explanation:

Part (a)

Let's replace x with 15 and evaluate to see if he is correct or not.

x/2 - 3 = 6

15/2 - 3 = 6

7.5 - 3 = 6  

4.5 = 6

We get a false statement after simplifying everything. We need to get the same number on both sides to get a true statement. Therefore, Ahmed is not correct.

===============================================

Part (b)

Let's solve for x. We do so by first adding 3 to both sides, and then multiplying both sides by 2. This follows PEMDAS in reverse, undoing everything to isolate the variable.

x/2 - 3 = 6

x/2 = 6+3 .... add 3 to both sides

x/2 = 9

x = 9*2 .... multiply both sides by 2

x = 18 is the answer

As a check, we'll use the same idea as part (a)

x/2 - 3 = 6

18/2 - 3 = 6

9 - 3 = 6

6 = 6

We get a true statement this time. This confirms x = 18

The amount of time required by Kyra to do the job alone is 12 hours.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Karl can clean a room in 3 hours. If his little sister Kyra helps, they can clean it in 2.4 hours.

The time will be calculated as below:-

( 1 / 3 ) + ( 1 / t) = ( 1 / 2.4 )

t = ( 3 x 2.4 ) / 0.6

t = 12 hours

Therefore, the amount of time required by Kyra to do the job alone is 12 hours.

The value of the 1.5(IQR) is 6 after using the formula of IQR which is IQR = Q3 - Q1 option (C) 6 is correct.

A median is a middle number in a series of numbers that have been arranged to lift, and it might be more informative of the set of data than the average. When there are extremes in the sequences that might affect the average of the numbers, the median is sometimes employed instead of the mean.

It is given that:

The five-number summary of a data set is given below.

Minimum: 3 Q1: 12 Median: 15 Q3: 16 Maximum: 20

As we know,

The IQR can be found using the formula:

IQR = Q3 - Q1

IQR = 16 - 12

IQR = 4

= 1.5(IQR)

1.5(4)

= 6

Thus, the value of the 1.5(IQR) is 6 after using the formula of IQR which is IQR = Q3 - Q1 option (C) 6 is correct.

Answer:

The answer is option A

y=-4x+2

Answer:

A y = -4x + 2

Step-by-step explanation:

1) x, y = -2, 10

y = -4x + 2

y = -4 . -2 + 2

y = 8 + 2

y = 10

2) x, y = 0, 2

y = -4x + 2

y = -4 . 0 + 2

y = 2

3) x, y = 1, -2

y = -4x + 2

y = -4 . 1 + 2

y = -4 + 2

y = -2

4) x, y = 3, -10

y = -4x + 2

y = -4 . 3 + 2

y = -12 + 2

y = 10

Answer:

Scale used for drawing is 1 cm = 1.75 m

Step-by-step explanation:

An architect makes a scale drawing of a house.

Actual width of porch  = 7 meters

Width of porch on drawing = 4 cm

So, Actual width = Drawing width

So, 4 cm = 7 m

1 cm = 1.75 m

So, Scale: 1 cm = 1.75 m

So, Option B is correct

B)1 cm = 1.75 m

Hence scale used for drawing is 1 cm = 1.75 m

Explanation:

The point (1,0) means x = 1 and y = 0 pair up together.

Replace each variable with those values to get

y = 3x

0 = 3(1)

0 = 3

We get a false statement, so that's why (1,0) is not a solution.

----------

If we plugged in x = 1, then we should get this y value

y = 3x

y = 3*1

y = 3

Meaning (1,3) is a solution. This point is on the line y = 3x.

Answer:

No

Step-by-step explanation:

Because when you take y = 0, you get x =0, not 1.

y =3x

0 = 3x

x = 0

(0, 0) ; (1, 3) (2, 6) . . .  are the solutions
