Someone help me on this question.

Answer:

its probably 8.5

Step-by-step explanation:

Answer:

Option B.

Step-by-step explanation:

Trigonometric area formula is Area = [tex]\frac{1}{2}\times absin(C)[/tex]

Where a and b are two sides of the triangle and C is the angle between these two sides.

As given in the figure, side a = 6 units, c = 2√2 units and ∠B = 80°

Then area of the triangle will be defined by the formula

Area = [tex]\frac{1}{2}\times acsin(B)[/tex]

        = [tex]\frac{1}{2}\times acsin(B)[/tex]

        = [tex]\frac{1}{2}\times 6\times 2\sqrt{2}\times sin(80)[/tex]

        = 6√2×sin80°

        = 6×(1.414)×0.9848

        = 8.36 square units

        ≈ 8.4 square units

Option B is the answer.

The effective annual yield for a certificate of deposit with a 6% annual interest rate compounded quarterly is approximately 6.14%.

To find the effective annual yield, we need to use the formula:

Effective Annual Yield = (1 + (interest rate / number of compounding periods))^number of compounding periods - 1

In this case, the interest rate is 6%, which is equivalent to 0.06. The number of compounding periods is 4 per year. Plugging these values into the formula, we get:

Effective Annual Yield = (1 + (0.06 / 4))^4 - 1

Calculating this, we find that the effective annual yield is approximately 6.14%.

Answer:

.70p  

p(1-.30)

Step-by-step explanation:

Tony plans to purchase a jacket that costs p dollars. In a week the jacket will go on sale for 30% off.

Tony writes althea following expression

p - .30p

Here P  or 1P  are same

So expression becomes 1p - 0.30p

Both are like terms

so we can subtract it

1p - 0.30p = 0.70p

Also we can write 1p - 0.30p  as  p(1-0.30)

We can take out p that is in common

Equivalent expression is .70p  and p(1-.30)

Answer: 6

Step-by-step explanation:

NOTE: log₆6 = 1

log₆6 + log₆(x - 5) = log₆6

  1      + log₆(x - 5) =    1

            log₆(x - 5) =    0

                    x - 5  =  6⁰

                    x - 5  =  1

                    x       = 6

The actual measurements are 12 feet by 24 feet.

The ratio between a distance on a map and its corresponding distance on the ground is referred to as the "map scale."

The scale of a map is the proportion between the distance shown on paper and the actual distance on the ground.

Given:

1 inch = 16 feet.

Dimension of bedroom on blue print is 0.75 inches x 1.5 inches.

so, the actual dimension of bedroom is

= 0.75 x 16 by 1.5 x 16

= 12 feet by 24 feet.

Hence, the actual measurements are 12 feet by 24 feet.

Answer:

The answer would be 4.8.

Step-by-step explanation:

The reason for it is because you subtract 37.63 - 32.83 and you get 4.8

Answer: 4

Step-by-step explanation: you will need to subtract 37.63 to 32.83, and so it will give you 4.8. since it is asking for an individual number between 2-5, it is reasonable to choose 4 (ideal because the final answer is 4.8.)

Answer:

f(x) = 2/3x +4

Step-by-step explanation:

The initial value is another name for the y intercept, so b = 4

Rate of change is another name for slope so m = 2/3

We can use the equation y =mx+b

y = 2/3 x + 4

We want it in function form

f(x) = 2/3x +4

Answer:

Given equation: [tex]Px+5 = -4x+ Q[/tex]

Add 4x on both sides we get;

Px + 5 + 4x = -4x + Qc+ 4x

Simplify:

Px +4x + 5 = Q

or

x(P+4) = Q - 5

Divide P+4 on both sides we get;

[tex]x = \frac{Q-5}{P+4}[/tex]

If we set Q-5 = 0 and P +4 = 0, there will be no solutions.

Since, No solution would mean that there is no answer to the equation.

⇒[tex]Q -5 = 0[/tex]

or

Q = 5

and

⇒[tex]P +4 = 0[/tex]

or

P= -4

Therefore, the values of P = -4 and Q = 5 results in an equation with no solutions.

Answer: P = -4 and Q = -5

Answer:

x = 57.22754579  

Step-by-step explanation:

We know cos 63 = adjacent/ hypotenuse

                  cos 63 =  15 sqrt(3)/x

Multiply each side by x

x cos 63 =15 sqrt( 3 )

Divide each side by cos 63

x cos (63)/ cos (63) = 15 sqrt(3)/cos (63)

  x = 15 sqrt(3)/ cos 63

x = 57.22754579

Answer:

Step-by-step explanation:

If the lines are parallel, then angles 1, 7, 3, and 5 are congruent because they are vertical/corresponding angles.

Therefore, they are all 113 degrees. For the rest of them, you just subtract from 180 to get 67. Therefore,

2 = 67 degrees

3 = 113 degrees

4 = 67 degrees

5 = 113 degrees

6 = 67 degrees

7 = 113 degrees

8 = 67 degrees

Answer:

f(1) = -3

f(8) =3

f^-1 (5) =2

f^-1 (2) =4

Step-by-step explanation:

f(1) = is the value when x=1  which is -3

f(8) = is the value when x=8 which is 3

f^-1(5) is x value when   y=5  so find y=5 in the table and read the x value  x=2

f^-1 (2) is the x value when y=2 so find y=2 in the table and read the x value  x=4

Answer:

< 8 = 60

<1 and <5 are corresponding angles

Step-by-step explanation:

<2 = <3  vertical angles

<3 = <6  alternate interior angles

<6 + <8 = 180  supplementary angles

120 + <8 = 180

Subtract 120 from side

120-120 + <8 = 180-120

< 8 = 60

<1 and <5 are corresponding angles

Corresponding angles occupy the same relative position at each intersection.

Answer:

The measure of [tex]\angle 8[/tex] is 60°

[tex]\angle 1[/tex] and [tex]\angle 5[/tex] are corresponding angles.

Step-by-step explanation:

Given that, [tex]m\angle 2= 120\°[/tex]

In the given diagram, [tex]\angle 2[/tex] and [tex]\angle 6[/tex] are corresponding angles and their measures are same.

So, [tex]m\angle 6= 120\°[/tex]

Now, [tex]\angle 6[/tex] and [tex]\angle 8[/tex] are pair of linear angles.

That means......

[tex]m\angle 6+m\angle 8= 180[/tex]°

[tex]\Rightarrow 120\°+m\angle 8=180\°\\ \\ \Rightarrow m\angle 8= 180\°-120\°\\ \\ \Rightarrow m\angle 8=60\°[/tex]

So, the measure of [tex]\angle 8[/tex] is 60°

The type of angles for [tex]\angle 1[/tex] and [tex]\angle 5[/tex] is corresponding.

The original price before a 25% discount, when the sales price is $40, is calculated as $40 divided by 0.75, resulting in $53.33.

To find the original price before a 25% discount, we can set up the equation where original price minus 25% of the original price equals the sales price. Let's call the original price 'P'. Then 0.25P is the amount discounted. The equation is P - 0.25P = $40. This simplifies to 0.75P = $40. To find P, divide both sides by 0.75, giving us P = $40 / 0.75. So, the original price P = $53.33.

The original price is $53.33.

If you have the sales price and the percent of discount, you can calculate the original price using the following steps:

To find the original price, we set up the equation:

0.75P = 40

Next, solve for P by dividing both sides by 0.75:

P = 40 / 0.75

P = $53.33

So, the original price of the item was $53.33 before the 25% discount was applied.

Answer:

Last choice

Step-by-step explanation:

Let's assume m is the "y" (dependent variable) and d is the "x" (independent variable) because the number of minutes is larger, and that would make more sense.

5760/4=1440

10080/7=1440

...

Slope is 1440, and it is direct variation

m=1440d

It COULD also be the third choice, but mathematical convention would have us put the coefficient first.

Answer:

13 glue sticks cost $25.22

Step-by-step explanation:

We can use ratio's to solve this problem.  We put price over number of sticks.

$7.76            x dollars

------------- = ---------------

4 sticks          13 sticks

Using cross products

7.76 * 13 = 4 * x

100.88 =4x

Divide each side by 4

100.88 /4 = 4x/4

$25.22 =x

Answer:39/4

Step-by-step explanation: What I'd do first is set the question up as an ordered pair, for example (x,y) have the uniforms be represented by x and the cost be represented by y. We know that the cost of five uniforms is $66, so we can substitute (x,y) into (5,66). We can then do the same for nine uniforms which is 105 (9,105). The equation we are going to use to find the slope is y2-y1/x2-x1 = 105-66/9-5.

This should result in 39/4. Make sure to always simplify when needed, in this case we don't have to.
