Answer:

128 is your answer

Step-by-step explanation:

Triangle's angles add up to 180 degrees because one exterior angle is equal to the sum of the other two angles in the triangle. In other words, the other two angles in the triangle (the ones that add up to form the exterior angle) must combine with the third angle to make a 180 angle

180-52=128

52+128=180

For this we can use an equation of y=mx+b, b will equal what she started with, and m will be how much she saves each week

Using this, we now can use the equation Y=15x+30, y equals the total she has saved, and x equals the weeks.

You should be able to use this equation to solve the rest now!

Answer:

298.24 mph at an angle of 89 degrees

Step-by-step explanation:

[tex]v_p[/tex] = Velocity of plane = 300 mph at 50 degrees

[tex]v_j[/tex] = Velocity of jet stream = 200 mph at 160 degrees

The velocity of the plane in component form is

[tex]v_p=300\cos50^{\circ}\hat{i}+300\sin50^{\circ}\hat{j}[/tex]

The velocity of the jet stream in component form is

[tex]v_j=200\cos160^{\circ}\hat{i}+200\sin160^{\circ}\hat{j}[/tex]

Resultant velocity is given by

[tex]v=(300\cos50^{\circ}+200\cos160^{\circ})\hat{i}+(300\sin50^{\circ}+200\sin160^{\circ})\hat{j}\\\Rightarrow v=4.9\hat{i}+298.2\hat{j}[/tex]

Magnitude is given by

[tex]|v|=\sqrt{4.9^2+298.2^2}\\\Rightarrow |v|=298.24\ \text{mph}[/tex]

Angle is given by

[tex]\theta=\tan^{-1}\dfrac{298.2}{4.9}=89^{\circ}[/tex]

The velocity of the plane is 298.24 mph at an angle of 89 degrees.

Answer:

2 and 3/4

Step-by-step explanation:

The pattern is to add 2/4 each time. to find the 6th term, add 2/4 three more times.

1 and 1/4 + 2/4 = 1 and 3/4

1 and 3/4 + 2/4 = 2 and 1/4

2 and 1/4 + 2/4 = 2 and 3/4

Step-by-step explanation:

Lets work out the equation for the given relationship.

This is a linear relationship.

Find the slope first:

Use one pair of points to get the equation:

Step-by-step explanation:

Answer:

x=1 and y=−1

Step-by-step explanation:

Multiply the first equation by 5,and multiply the second equation by 6.

5(−3x−6y=3)

6(5x+5y=0)

Becomes:

−15x−30y=15

30x+30y=0

Add these equations to eliminate y:

15x=15

Then solve15x=15for x:

15x=15

15x

15

=

15

15

(Divide both sides by 15)

x=1

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

−3x−6y=3

Substitute1forxin−3x−6y=3:

(−3)(1)−6y=3

−6y−3=3(Simplify both sides of the equation)

−6y−3+3=3+3(Add 3 to both sides)

−6y=6

−6y

−6

=

6

−6

(Divide both sides by -6)

y=−1

Answer:

$324

Step-by-step explanation:

(1.08)(300) = 324

Answer:

The total price of the bicycle including sales tax is $324.

Explanation:

The price of a bicycle = $300

Rate of sales tax = 8%

Amount of tax = 8% x 300

                     = [tex]\frac{8}{100}[/tex] x 300

                     = 8 x 3

                      = 24

Cost of bicycle including tax= Price of cycle + Amount of tax = 300+24=324  

= $324

Answer:

Total cost =3over8 x 48 x0. 55=9.9

Answer:

$9.90

Step-by-step explanation:

First, we need to find the number of vanilla cupcakes.

The question tell us that 3/8 of the 48 cupcakes are Vanilla flavored, so we can start by dividing 48 by 8 to find what 1/8 of 48 is:

48/8 = 6

1/8 of 48 = 6

Now to find 3/8, we just need to multiply that number by 3:

6 x 3 = 18

3/8 of 48 = 18

So now we know that she bought 18 vanilla cupcakes.

Finally to find the price, we just need to multiply the price per cupcake by the number of cupcakes:

$0.55 per cupcake x 18 cupcakes = 0.55 x 18 = $9.90

The total cost of the vanilla cupcakes was $9.90

Answer:

$3,153.32

Step-by-step explanation:

Given that

The deposited amount is $3,000

The annual interest rate is 1.25%

So, the semi-annual interest rate is 1.25% ÷2  = 0.625%

And, the time period = 4 × 2 = 8

We need to find out the final balance

So,

As we know that

Future value = Present value × (1 + rate of interest)^number of years

= $3,000 × (1 + 0.625%)^8

= $3,153.32

Answer:

8.8

Step-by-step explanation:

Normally, to find the distance between two points, you would use the distance formula, but these two points have the same x-coordinate, meaning they will form a vertical line when connected. To find the length of a vertical line you find the distance between the y-coordinates, in this case -4.7 and 4.1. Finding the distance is the same as finding the absolute value of the difference:

|4.1 -(-4.7)|

|4.1 + 4.7|

|8.8|

Answer:

The answer is x=-6, x=8

Step-by-step explanation:

I recommend using the quadratic formula to solve this problem.

x^2=a

-2x=b

-48=c

Plug it into the quadratic formula.

New equation:[tex]\frac{2+-\sqrt{(-2)^2-4(1)(-48)}}{2(1)}[/tex]

Simplify

Equation: [tex]\frac{2+-\sqrt{4+192}}{2}[/tex]

Add 4 and 192.

Equation: [tex]\frac{2+-\sqrt{196}}{2}[/tex]

Do the square root of 196.

Equation: [tex]\frac{2+-14}{2}[/tex]

Make into two different equations.

Equation 1: [tex]\frac{2+14}{2}[/tex]

Equation 2: [tex]\frac{2-14}{2}[/tex]

Solve the two equations and you will get -6 and 8.  Hope this helps!

[tex] \sf \: x ^ { 2 } - 2 x - 48 = 0[/tex]

All equations of the form ax² + bx + c = 0 can be solved using the quadratic formula: [tex]\sf \frac{-b±\sqrt{b^{2}-4ac}}{2a}[/tex]. The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.

[tex] \sf \: x^{2}-2x-48=0 [/tex]

This equation is in standard form: ax² + bx + c = 0 Substitute 1 for a, -2 for b and -48 for c in the quadratic formula.

[tex] \sf \: x=\frac{-\left(-2\right)±\sqrt{\left(-2\right)^{2}-4\left(-48\right)}}{2} \\ [/tex]

Square -2.

[tex] \sf \: x=\frac{-\left(-2\right)±\sqrt{4-4\left(-48\right)}}{2} \\ [/tex]

Multiply -4 times -48.

[tex] \sf \: x=\frac{-\left(-2\right)±\sqrt{4+192}}{2} \\ [/tex]

Add 4 to 192.

[tex] \sf \: x=\frac{-\left(-2\right)±\sqrt{196}}{2} \\ [/tex]

Take the square root of 196.

[tex] \sf \: x=\frac{-\left(-2\right)±14}{2} \\ [/tex]

The opposite of -2 is 2.

[tex] \sf \: x=\frac{2±14}{2} \\ [/tex]

Now solve the equation [tex]\sf\:x=\frac{2±14}{2}[/tex] when ± is plus. Add 2 to 14.

[tex] \sf \: x=\frac{16}{2} \\ [/tex]

Divide 16 by 2.

[tex] \boxed{ \boxed{ \bf \: x=8 }}[/tex]

Now solve the equation [tex]\sf\:x=\frac{2±14}{2} [/tex] when ± is minus. Subtract 14 from 2.

[tex] \sf \: x=\frac{-12}{2} \\ [/tex]

Divide -12 by 2.

[tex] \boxed{\boxed{ \bf \: x=-6 }}[/tex]

The equation is now solved.

Answer:

The probability of picking a green is 0.4

Step-by-step explanation:

Mathematically, when we talk of the highest possibility an event can have, we have the answer as 1

Hence, when we add up all the probabilities, it is expected that we arrive at a value equal to 1

Thus, the probability of selecting each individual colors add up to 1

since we have the probability of three colors, the probability of the fourth will be the sum of the others subtracted from 1

we have the probability of picking a green as;

1 - 0.25 - 0.15 - 0.2 = 0.4

Step-by-step explanation:

there is nothing its just a dark screen?

The 1st figure is correct, the 4th one seems very similar to the 1st one. But the red shape is closer to line k. So the 1st one is correct

The figure that illustrates a reflection in line k is figure C.

We have given that the figure.

We have to determine the correct option a reflection in line k.

A reflecting line is a perpendicular bisector.

When a figure is reflected, the reflecting line is the perpendicular bisector of all segments that connect pre-image points to their corresponding image points.

Therefore option c is correct.

Therefore, the figure that illustrates a reflection in line k is figure C.
