Answer:

8.9

Step-by-step explanation:

Use Pemdas or Bedmas ( Brackets, Exponents, Division, Multiplication, Addition, Subtraction.

First add 4.5 and 7.6, you get 12.1

Now do the division, 8/2.5 = 3.2

Lastly you subtract, 12.1-3.2 = 8.9

Answer:

5.38%

966/52 = 0.05383022774

Step-by-step explanation:

5.38 can also be 5.4%

As proved.

We can write this as 52>52.2

To find  52>52.49 we only have to divide it by the larger number.

52.49/966 = 0.05433747412

or multiply to check.

966 x 0.054 = 52.164   sales tax  =  5.4% paid

966 x 0.053835 = 52.00461 = 5.38 % paid  

Both these amounts or in-between would be sales tax percentage

But exact would be 5.38%

Answer:

5.383%

Step-by-step explanation:

To find what percent a part is of a number, divide the part by the number and multiply by 100%.

part = 52

number = 966

percent = 52/966 * 100% = 5.383%

Answer:

supplementary

Step-by-step explanation:

∠ 1 and ∠ 2 are adjacent angles and supplementary.

Answer:

Angles 1 and 2 are supplementary angles.

Step-by-step explanation:

This means that angles 1 and 2 add up to 180 degrees.

Answer:

y = 3x - 9

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 3x + 4 ← is in slope- intercept form

with slope m = 3

Parallel lines have equal slopes, thus

y = 3x + c ← is the partial equation

To find c substitute (2, - 3) into the partial equation

- 3 = 6 + c ⇒ c = - 3 - 6 = - 9

y = 3x - 9 ← equation of parallel line

Answer:

Step-by-step explanation:

Since 20% is taken off, 100%-20% or 80% remains.

80% of $65 is 0.80�$65 or $52.  That's the price without tax.  

The tax on $52 is 0.06�$52 or $3.12,

$52 + $3.12 = $55.12

9.696

Step-by-step explanation:

Answer:

x = 9.7 feet

Step-by-step explanation:

Use tan to find the value of x

tan 22 = [tex]\frac{x}{24}[/tex]       Simplify

0.404 = [tex]\frac{x}{24}[/tex]       Multiply both sides by 24

x = 9.696        Round this answer to the nearest tenth of a foot

x = 9.7 feet

Answer:

x= 1.27, y= 11.4 (to 3s.f.)

Step-by-step explanation:

5x -y= -5 -----(1)

3x -5y= -3 -----(2)

From (1):

-y= -5x -5

divide by -1 throughout:

y= 5x +5 -----(3)

Subst. (3) into (2):

3x -5(5x +5)= -3

3x -25x +25= -3 (expand)

-22x= -3 -25

-22x= -28

divide by -22 throughout:

x= 1.2727 (5 s.f.)

x= 1.27 (3 s.f.)

subst. into (3):

y= 5(1.2727) +5

y= 11.4 (3 s.f.)

Answer:

a=5 b=0 c=3

Step-by-step explanation:

The quadratic equation is written as

ax^2 + bx+c =0

5x^2 +3 =0

5x^2 +0x  +3 =0

a=5 b=0 c=3

The closest lower value would be 10.

10^2 = 100

So the two consecutive numbers would be 10 and 11

Answer:

$535.78

Step-by-step explanation:

First find out the annual earnings. So multiply 3.4% by 445

0.034 x 445 = 15.13

That's what the account earns every year. Now multiply it by 6 to know what it'll get in 6 years.

15.13 x 6 = 90.78

Now add that to the initial value.

90.78 + 445 = 535.78

That's the balance in the account after 6 years...

$535.78

Answer:

Step-by-step explanation:

cos150°

= - cos(180 - 150)°

= - cos30°

= - [tex]\frac{\sqrt{3} }{2}[/tex]

-------------------------

sin150°

= sin (180 - 150)°

= sin30°

= [tex]\frac{1}{2}[/tex]

The trigonometric values for cos(150°) and sin(150°) are -√3/2 and 1/2, respectively.

To find the trigonometric values of cos(150°) and sin(150°), we can use the unit circle and the angle sum formulas.

cos(150°):

We know that cos(180° - θ) = -cos(θ). Therefore, we can rewrite cos(150°) as cos(180° - 30°). Since cos(30°) = √3/2, we have:

cos(150°) = -cos(30°) = -√3/2.

sin(150°):

We know that sin(180° - θ) = sin(θ). Therefore, we can rewrite sin(150°) as sin(180° - 30°). Since sin(30°) = 1/2, we have:

sin(150°) = sin(30°) = 1/2.

Answer:

c) y= 2x +4

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the gradient and c is the y-intercept.

Parallel lines have the same gradient.

Gradient of given line= 2

m= 2

y= 2x +c

To find the value of c, substitute a pair of coordinates into the equation.

when x= -1, y=2,

2= 2(-1) +c

2= c -2

c= 2 +2

c= 4

Thus, the equation of the line is y= 2x +4.

Answer: B

Step-by-step explanation:

Given that the scatter plot with points going down from about zero comma 4 to the right to about 7 comma zero. That is, (0 , 4 ) to ( 7, 0 )

Let's first find the slope M

M = (0 - 4)/( 7 - 0)

M = - 4/7

Since the line of best fit is linear, let adopt general equation of straight line

Y = MX + C

As the line passes through ( 0 , 4 )

Substitutes for Y and X

4 = - 4/7 (0) + C

C = 4

Where C = intercept

The equation for the line of best fit to represent the data will be:

Y = - 4/7 X + 4

Y equals negative two thirds times x plus 4

Answer:

It is B.
