Mr James spent $62.60 ordering sandwiches for his staff he tipped the delivery driver 20% how much did he spent altogether.

Answer:

x = 7

Step-by-step explanation:

Since, BD is the angle bisector of ∠ABC,

By angle bisector theorem,

∠ABD ≅ ∠CBD

m∠ABD = m∠CBD

(3x - 1) = (34 - 2x)

3x + 2x = 34 + 1

5x = 35

x = 7

Answer:

7

Answer:

The domain is all real number:

i.e.

[tex]-\infty \:<x<\infty \:[/tex]

Therefore,

[tex]\mathrm{Domain\:of\:}\:10^x\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]

Step-by-step explanation:

Given the function

y = 10ˣ

Determining the domain of the function y = 10ˣ :

We know that the domain of the function is the set of input or arguments for which the function is real and defined.  

In other words,

From the graph, it is clear that the function has no undefine points nor domain constraints.

Thus, the domain is all real number:

i.e.

[tex]-\infty \:<x<\infty \:[/tex]

Therefore,

[tex]\mathrm{Domain\:of\:}\:10^x\::\quad \begin{bmatrix}\mathrm{Solution:}\:&\:-\infty \:<x<\infty \\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:\infty \:\right)\end{bmatrix}[/tex]

Answer:

The domain is all real numbers

Step-by-step explanation:

Step-by-step explanation:

Since triangles ABC and DEF are congruent,

Angle D = Angle A.

=> (2y - 5)° = 65°, 2y - 5 = 65, y = 35.

Also side EF = side BC.

=> 2x + y = 90.6, 2x = 90.6 - (35) = 55.6, x = 27.8.

Answer: Y = 35, X = 27.8

Step-by-step explanation:

First you need to find Y. So, you do 2y - 5 = 65. First you add 5 to both sides, this will give you 2y = 70. Then divide both sides by 2 to get y = 35. Then in order to find x we do 2x + y = 90.6. First we change Y to the 35, as that is what y equals, then subtract both sides by 35 to get 2x = 55.6. Then you divide both sides by 2 to get x = 27.8.

Step-by-step explanation:

Using the double angle identity for sine

sin2x = 2sinxcosx

Consider left side

cos20°cos40°cos80°

= [tex]\frac{1}{2sin20}[/tex] (2sin20°cos20°)cos40°cos80°

= [tex]\frac{1}{4sin20}[/tex] (2sin40°cos40°)cos80°

= [tex]\frac{1}{4sin20}[/tex] (sin80°cos80° )

= [tex]\frac{1}{8sin20}[/tex] (2sin80°cos80° )

= [tex]\frac{1}{8sin20}[/tex] . sin160°

= [tex]\frac{1}{8sin20}[/tex] . sin(180 - 20)°

= [tex]\frac{1}{8sin20}[/tex] . sin20°

= [tex]\frac{1}{8}[/tex] = right side , thus proven

Answer:

1.475 × 10¹⁴ mi

Step-by-step explanation:

Since  1 light year = 5.9 × 10⁹ mi and the Earth is located about 25,000 light-years from the Milky Way's rim, the approximate distance, in miles, from Earth to the rim of the Milky Way is 25,000 light year = 25,000 × 1 light year

= 25,000 × 5.9 × 10⁹ mi

= 147.5 × 10¹² mi

= 1.475 × 10¹⁴ mi

Answer:

sum of interior angles of octagon is 1080 degrees

From figure ,

136 + 132 + 129 + 116 + 158 + 141 + 124 + x = 1080

so, x = 1080 - 936

        = 144

Step-by-step explanation: Simply add the angles and substract the sum from 1080 which is the sum of interior angles of octagon

Answer:

144 degrees.

Step-by-step explanation:

There are 8 sides to this polygon so the total internal of

angles = 180( 8 - 2)

= 1080

Adding up the 7 given angle we get  936

So x = 1080 - 936

= 144.

Answer:

40

Step-by-step explanation:

To solve this question you will need to use BEDMAS which is the order of which numbers you have to solve first. In this case you need to solve the brackets first, then the exponent, and then lastly the addition.

 3^3 + 3(4 + 1/3)

= 3^3 + 3(13/3)

= 27 + 3 x 13/3

= 27 + 13

= 40

Answer:

-3

Step-by-step explanation:

divide both side by 6 to find t

Answer:

€120

Step-by-step explanation:

Let us represent

Ann = x

Brian = y

Carol = z

€400 is divided between Ann, Brian and Carol

Hence: x + y + z = €400...... Equation 1

Ann has twice as much as Brian

Hence:

x = 2y

Brian has three times as much as Carol.

y = 3z

z = y/3

We substitute

x + y + z = €400...... Equation 1

2y + y + y/3= €400

Multiply both sides by 3

2y × 3 + y × 3 + y/3 × 3 = €400 × 3

6y + 3y + y = €1200

10y = €1200

y = €1200/10

y = €120

How much does Brian receives ?

Since, Brian = y

Brian receives €120

Hey there!

Answer:

option D

Step-by-step explanation:

First you must find g(n) given that n is -3n:

g(-3n) = -3n - 1

Then plug that in f(n) as the new n:

f(n) 3( -3n - 1) + 5

= -9n -3 + 5

= -9n + 2

So option D

Answer:

59

Step-by-step explanation:

1) so you start with the mean being 72x5=360

2)100+42+87+66=295

3) 360-295=65

(you get the 5 from the amount of numbers there are) P.S sorry if I'm wrong or this doesn't help

She needs to convert all the numbers be be the same type ( fraction or decimal).

With the numbers she has it would be easiest to convert all the numbers to decimals.

72/80 = 0.9

3 1/5 = 3.3

Pi = 3.14

Now she can arrange the decimals in order:

-2.9, 0.9, 2.979, 3.14, 3.2

She needs to switch 3 1/5 and pi

Answer:

3 1/5 is tha one

Step-by-step explanation:

Answer:

(-7,-3)

Step-by-step explanation:

You keep the -3 since that is the y but the x will become negative because you are reflecting to the left and not the right, making the x then negative.

Answer: (-7,-3)

Step-by-step explanation:

The point (7,-3) is located in the fourth quadrant  mean that if you reflect the point across the  y a-xis, it should end up in the third quadrant.

If you flip a point over the y axis, the x coordinate switches.

(7,-3) ⇒ (-7,-3)

Answer: $213

Step-by-step explanation:

First find out how much is spent on the other things:

Utilities

= 15% * 420

= $63

Internet services

= 1/5 * 420

= $84

Phone service

= 1/7 * 420

= $60

The amount left for food is therefore:

= 420 - money spent on other things

= 420 - 63 - 84 - 60

= $213

Answer: Add the two equations together to eliminate y

Step-by-step explanation:

X+y=3

4x-y=7

I would use elimination since one equation has +y and one equation has -y

Add the two equations together

X+y=3

4x-y=7

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

5x = 10

Step-by-step explanation:

Since UV bisects TW, TW also bisects UV.

=> Line segments UV and TW bisect each other.

=> 4y - 3 = 2y + 1 and 3x + 8 = 3y + 2

=> 2y = 4 and 3x = 3y - 6

=> y = 2 and x = y - 2

=> y = 2 and x = (2) - 2

=> y = 2 and x = 0.

Answer:

y= 181/7 or 25.86

Answer:

Ciera is driving at a faster rate.

Step-by-step explanation:

You calculate speed, by dividing distance by time.

So 18 divided by 24 is 0.75. That is Ciera's speed.

And then to calculate the other person/thing's speed you have to divide 46 by 60 minutes (equal to one hour). The speed calculates to 0.7666666667

Therefore, Ciera is driving faster.

Answer:

2n³ - 3n² - 7n + 3

Step-by-step explanation:

Given

(n² - 3n + 1)(2n + 3)

Each term in the second factor is multiplied by each term in the first factor, that is

n²(2n + 3) - 3n(2n + 3) + 1(2n + 3) ← distribute the parenthesis

= 2n³ + 3n² - 6n² - 9n + 2n + 3 ← collect like terms

= 2n³ - 3n² - 7n + 3

Answer:

1 mile = 0.5 cm

Step-by-step explanation:

I hope this helps!

Hey again!

The answer to your question is 2 cm = 1 mile

We can solve this by doing 9/4.5, and we get 2. This means that every 2 centimeters in the scale drawing is equal to 1 mile in the actual.
