Answer:

19 miles

Step-by-step explanation:

Given that :

Shape of route is rectangular :

Length of route = 5.5 miles

Width of route = 4 miles

Distance of one complete trip = perimeter of the rectangular route :

Perimeter of a rectangle :

P = 2(length + Width)

P = 2(5.5 + 4)

P = 2(9.5)

P = 19 miles

Hence one complete trip is 19 miles long.

Answer:

[tex]\Huge\boxed{x=53}[/tex]

Step-by-step explanation:

Hello There!

Once again we need to use trigonometry to solve for X

Here are the Trigonometric Ratios:

Sin = Opposite divided by hypotenuse

Cos = adjacent divided by hypotenuse

Tan = Opposite divided by adjacent

We are given the adjacent side of x (45) and the hypotenuse (75) so we need to use cos

Remember cos = adjacent divided by hypotenuse

Now we create an equation

[tex]cos(x)=\frac{45}{75}\\\frac{45}{75} =.6[/tex]

now we have

[tex]cos(x)=.6[/tex]

like always we want to get rid of cos

to do so we take the inverse of cos (arccos^-1) and apply that to each side

[tex]arccos^-^1(cos(x))=x\\arccos^-^1(.6)=53.13010235[/tex]

finally we round to the nearest degree

we're left with x = 53

Answer:

$6

Step-by-step explanation:

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15

there's 10

1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 12, 13, 14, 15

1 + 9 = 10

10 + 10 = 20

2, 3, 4, 5, 6, 7, 8, 11, 12, 13, 14, 15

2 + 8 = 10

20 + 10 = 30

3, 4, 5, 6, 7, 11, 12, 13, 14, 15

3 + 7 = 10

30 + 10 = 40

4, 5, 6, 11, 12, 13, 14, 15

4 + 6 = 10

40 + 10 = 50

5, 11, 12, 13, 14, 15

5 + 15 = 20

50 + 20 = 70

11, 12, 13, 14

11 + 14 = 25

70 + 25 = 95

12, 13

12 + 13 = 25

95 + 25 = 120

she would 120 nickels which is

120 x 5 = 600 cents or $6

Answer:

The answer is 5 beecause coefficients are the number when you multiply a number and a variable. For example 5a the coefficient in that term is 5 if you have 48e the coefficient is 48. So the coefficient is the number when you multiply a number times a variable.

Answer:

I think x is 60 and y is 50.

Step-by-step explanation:

70 + 50 = 120

180 - 120 = 60

x = 60

50 + 50 = 100

70 + 60 = 130

130 + 100 = 230

230 - 180 = 50

y = 50

I hope this helps u! :D

Answer:

x=60 y=50

Step-by-step explanation:

180 is equal to the whole triangle so 50+70=120 and 180-120= 60

the other triangle has a missing value by doing the same thing before we can figure out that the missing value is 70. 70+x which is 60 equals 130. A straight line is equal to 180 so 180-130= 50.

Hope I could help!

Answer:

what am i sopposed to do?

Step-by-step explanation:

Answer:

Two adult tickets and 5 student tickets

Step-by-step explanation:

Let a=adult tickets   Let s=student tickets

You know that each adult ticket is $9.10 and each student ticket cost $7.75. At the end, it cost $56.95 for both students and adults so the first equation should be 9.10a+7.75s=56.95. To get the second equation, you know that Mrs. Williams purchased 7 tickets in total that were both students and adults. Therefore, the second equation should be a+s=7. The two equations are 9.10a+7.75s=56.95

a+s=7.

Now, use substitution to solve this. I will isolate s from this equation so the new equation should be s=-a+7. Plug in this equation to the other equation, it will look like this 9.10a+7.75(-a+7)=56.95. Simplify this to get 9.10a-7.75a+54.25=56.95. Simplify this again and the equation will become 1.35a=2.70. Then divide 1.35 by each side to get a=2. This Mrs. Williams bought two adult tickets. Plug in 2 into a+s=7, it will look like this (2)+s=7. Simplify this and get s=5. This means Mrs. Williams bought five adult tickets. Therefore she bought 2 adult tickets and 5 student tickets.

Hope this helps

Answer:

Yes, the same answer is obtained.

Step-by-step explanation:

According to Mr. Carlevato, [tex]2(2x+3)[/tex] is equal to [tex]4x+6[/tex]. However, [tex]2(2x+3)[/tex] is not equal to [tex]4x+6[/tex] according to Mr. Burrows.

Put [tex]x=5[/tex] in [tex]2(2x+3)[/tex]

[tex]2[2(5)+3]=2(10+3)=2(13)=26[/tex]

Put [tex]x=5[/tex] in [tex]4x+6[/tex]

[tex]4x+6=4(5)+6=20+6=26[/tex]

Therefore,

[tex]2(2x+3)=4x+6[/tex]

Yes, the same answer is obtained.

Answer:

Step-by-step explanation:

Width =x

Length = 2*x = 2x

Diagonal = 5√5

Use Pythagorean theorem

Length² + Width² = diagonal²

  (2x)²    + x²        = (5√5)²      

{[tex](5\sqrt{5})^{2}=5\sqrt{5} *5\sqrt{5}=5*5*\sqrt{5*5}=25*5=75[/tex]}

     4x²   + x²        = 75

                      5x² = 75

                        x²  = 75/5

                       x²   = 15

                        x = √15

Width = √15

Length = 2√15

Area of rectangle = length *width

                             = √15 *2√15

                             [tex]= 2* \sqrt{15*15}\\\\= 2*15\\= 30[/tex]

                             = 30 square units

[tex](d)\ 1.94 * 10 ^{-5},\ \ 1.25 *10 ^{-2}, \ \ 8.1 *10^{4},\ \ 6 * 10^4[/tex]

Required

Which list is in ascending order

To do this, we analyze each of the options 1 after the other.

[tex](a)\ 1.94 * 10 ^{-5},\ \ 1.25 *10 ^{-2},\ \ 6 *10 ^{4},\ \ 8.1 *10^{4}[/tex]

Convert each list item to decimal

[tex]1.94 * 10 ^-5 = 0.0000194[/tex]

[tex]1.25 *10 ^-2 = 0.0125[/tex]

[tex]6 *10^{4} = 60000[/tex]

[tex]8.1 *10^{4} = 81000[/tex]

The list is in ascending order because:

[tex]0.0000194 < 0.0125 < 60000 < 81000[/tex]

No need to test other options
