What is the absolute value of -8?

Answer:

The slope of line 1 is: (7-3) / (-5 - -9) = 4/4 = 1

The slope of line 2 is: (2-6) / (-7 - -11) = -4/4 = -1

Yes, they are perpendicular

Step-by-step explanation:

The slope of line 1 is: (7-3) / (-5 - -9) = 4/4 = 1

The slope of line 2 is: (2-6) / (-7 - -11) = -4/4 = -1

slope 2 = - 1/1 = - 1/slope 1

Answer:

Step-by-step explanation:

2a+3b+2k= $3.19

3a+4b+2k=$4.12

1a+1b+4k=$3.01

The system of equation that can be used to solve these scenario are          2a + 3b + 2k = 3.19, 0a + 4b + 2k = 4.12 and  1a + 1b + 4k = 3.01.

A linear equation consist of variables and constant sperated by arithmetic operations which has highest degree of 1.

We know that a system of equations is formed when we have two or more than two linear equations in two or more than two variables and a system of equations is consistent when the number of variables is equal to or less than the number of equations.

Given in this questin is 3 variables Applles(a). Bananas(b) and Kiwis(k) and we can form three equations in three variables they are,

2a + 3b + 2k = 3.19...(i)

0a + 4b + 2k = 4.12...(ii)

1a + 1b + 4k = 3.01...(iii)

We can solve this system of equation by first multiplying eqn(iii) by 2 and then subtracting it from eqn(i) to eliminate variable 'a' and then equating with eqn(ii) to eliminate variable 'b' or 'k'

Answer:

1 hour= 45 miles

1/2 hour=22.5 miles

3 hours= 135

Step-by-step explanation:

just work out one hour by halving 90 miles which is 45. Then work out the rest by halving again and multiplying by 3.

Answer:

1st way:

90/2=45

1 hour = 45 miles

45/2=22.5

0.5 hour = 22.5 miles

45+22.5=67.5

1.5 hour = 67.5 miles

67.5x2=135

3 hours = 135 miles

2nd way:

90 miles - 2 hours

1 hour - 60 minutes

60x2=120

90/120=0.75

1 minute - 0.75 miles

0.75x60=45

1 hour = 45 miles

60:2=30

60+30=90

0.75x90=67.5

1.5 hour = 67.5 miles

60x3=180

0.75x180=135

3 hours = 135 miles

Answer:

The value of mEFD = 214°

Step-by-step explanation:

Given that the measure of the degree of one of the central angles of an inner circle is 146°.

We know that sum of all central angles is 360°.

In other words, in our case

mEFD + 146° = 360°

Thus, we can determine the mEFD using the equation

mEFD + 146° = 360°

so subtracting 146° to both sides

mEFD + 146° - 146°  = 360° - 146°

mEFD = 214°

Therefore, the value of mEFD = 214°

Answer:

B: 1 to 5

Step-by-step explanation:

3 hours is to 15 miles as 1 hour is to 5 miles (division by 3)

Answer:

The sides can be 38 and 24.

Step-by-step explanation:

Consider the provided information.

The given options are: a) 15, b) 24, c)38, d)41, E)53

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

Here a=12 and b=28 we need to find c

The sum of 12 and 28 is 40.

So, It means the side can not be 41 and 53 as it is greater than 40.

Now let the third side is 15.

Then the sides are 12, 28  and 15

The sum of two smaller sides: 12+15=27

But 27 is less than 28.

So the side can't be 15.

Now let the third side is 24.

Then the sides are 12, 28  and 24

The sum of two smaller sides: 12+24=36

But 36 is greater than 28.

So the side can be 24.

Now let the third side is 38.

Then the sides are 12, 28 and 38

The sum of two smaller sides: 12+28=40

But 40 is greater than 38.

So the side can be 38.

Hence, the sides can be 38 and 24.

Answer:

A. 60 degrees

Step-by-step explanation:

The sum of the abgles in a triangle is 180°. We are already given 96° and 24°.

so we will subtract the given values from 180 to find the third angle

180-(96+24)=180-120=60°

The answer is A. 60°

Answer:

272

Step-by-step explanation:

45 and a third = 45 1/3

one sixth = 1/6

hence:

45 and a third divided by one sixth =

= 45 1/3 ÷ 1/6

= 136/3 ÷ 1/6

We convert to multiplication by converting 1/6 to its reciprocal which is 6/1

Hence:

= 136/3 ×6/1

= 272

Answer:

8*2^(n-1)

Step-by-step explanation:

This is a geometric sequence since we multiply from the previous term.

a_n = a_1 * common ratio^(n-1) where a_n is the nth number and a_1 is the first.

The first term is 8, so we have

a_n = 8*<common ratio>^(n-1) = 8*2^(n-1)

Answer:

32

Step-by-step explanation:

As per what is given

- the product of 4 and a number decreased by 7 (4 times that number let us call it x, minus 7)

- equals 100, the equation formed equals 100

Form an equation;

4(x - 7) = 100

Solve using inverse operations;

4(x - 7) = 100

   /4        /4

x - 7 = 25

   +7     +7

x = 32

Answer:

20 ; $135 ; service charge for 3 hours spent is $135

Step-by-step explanation:

Given that :

Service fee equation model :

C(h)= 75 + 20h

C = total cost of the service call

h = number of hours the plumber spends working on the problem

The charge per hour is the gradient or slope of the linear equation. From the equation, the slope is of the equation is related to bx from. The general form of a linear equation where b = gradient or slope(charge per hour) and x = number of hours

bx = 20h

b = 20

Charge per hour = 20

C(3) = 75 + 20(3)

75 + 60 = 135

This means that total service call charge for a plumber who spends three hours fixing a problem is $135
