Louis traveled 2,795 on an airplane from
Los Angeles to New York City. Then he
switched planes and traveled 3,460
miles to London. After that, he switched
planes again and traveled 889 miles from
London to Rome. How many miles did he
fly in all?

Answer:

9 lb 4 oz

Step-by-step explanation:

Justin weighed 8 lb 12 oz at birth. He gained 8 ounces by his two-week checkup. So,

8 lb 12 oz + 8 oz = 8 lb 20 oz

But, 16 oz equals one pound. So,

20 oz = 1 lb with 4 oz remaining

Now add them together.

8 lb + 1 lb 4 oz = 9 lb 4 oz

Justin's weight is 9 lb 4 oz.

Hope that helps.

Answer:

x=1/4

y=1/2

Step-by-step explanation:

Given:

-2.4x+3.6y=1.2

2.4x + 1.2y=1.2

-2.4x+3.6y=1.2

Divide through by 1.2

-2x+3y=1

2.4x + 1.2y=1.2

Divide through by 1.2

2x+y=1

-2x+3y=1 (1)

2x+y=1 (2)

From 2

y=1-2x

Substitute y=1-2x into (1)

-2x+3y=1

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

-2x+3-6x=1

-8x=1-3

-8x=-2

Divide both sides by -8

x=1/4

Substitute x=1/4 into (2)

2x+y=1

2(1/4)+y=1

2/4+y=1

1/2+y=1

y=1-1/2

y=1/2

x=1/4

y=1/2

Step-by-step explanation:

Using the foil method, 3x*2x+3x*3+-2*2x+-2*3

The coordinates of the inverse are (1.25, 1) (2.50, 2), (6.25, 5), (18,75, 15) and (25.00, 20)

The table of values is given as:

Gallons       Cost

1                      1.25

2                     2.50

5                     6.25

15                     18.75

20                    25.00

The inverse of the above table would have the following header

Cost     Gallons

When the inverse table is populated, we have:

Cost    Gallons

1.25          1

2.50        2

6.25         5

18.75        15

25.00      20

The coordinates are: (1.25, 1) (2.50, 2), (6.25, 5), (18,75, 15) and (25.00, 20)

Hence, the coordinates of the inverse are (1.25, 1) (2.50, 2), (6.25, 5), (18,75, 15) and (25.00, 20)

Answer:

3.92$

Step-by-step explanation:

The first step is to deduct 20% of 4.50 from 4.50.

20% of 4.50 is 0.2 x 4.50 = .90

4.50 - 0.90 = 3.60

That's the new price without the sales tax.

Now we need to add 9% of 3.60 to 3.60 to get the final cost.

9% of 3.60 is .09 x 3.60 = 0.32

3.60 + .32 = $3.92

Hope it helps.. If yes mark me BRAINLIEST

Tysm!

Answer:

$3.92

Step-by-step explanation:

Hello! For this question we need to gather up all the facts before we could answer it!

The original nail polish cost was $4.50

But the bottle was marked down by 20%

Then has a sales tax of 9%

So let's multiply 4.50 x 0.2 = 0.9

With that we need to subtract off of the original price because it is decreasing.

4.50 - 0.9 = 3.60

But that is not the final price because the bottle has a sales tax! We need to multiply the price after the 20% mark down, so, 3.60 x 0.09 = 0.324

And Then because we are dealing with money, we are going to make sure that we are only adding a decimal that goes up to the hundredths place.

Add: 3.60 + 0.32 = 3.92

The Final price of the nail polish that Dora bought would be $3.92. Which is actually a 0.58 cents drop!

Answer:

(C)[tex]-6x+8(-x+6) = 6[/tex]

Step-by-step explanation:

Given the system of equations

[tex]x+y=6 \\-6x+8y = 6[/tex]

From the first equation:

x+y=6

Making y the subject, we have:

y=-x+6

Substituting y=-x+6 into the second equation, we obtain:

[tex]-6x+8(-x+6) = 6[/tex]

The correct option is C.

NOTE: The goal of substitution is to reduce the number of unknown variables to 1. Therefore, after the substitution, if you still have the two unknown, you might have done something incorrect.

Answer:

Using the given information in the problem, the value of f  is 9

Step-by-step explanation:

In this problem, we will be using tangent, Tangent is the opposite side divided by the adjacent side from the given angle. The given angle that we will be using for this problem is the measurement of ∠F which is 58°. We will use this for our equation.

Let's set up our equation for tangent.

[tex]Tan(58)=\frac{15}{f}[/tex]

Since we are looking for f , then we will rearrange the equation.

[tex]f=\frac{15}{tan(58)}[/tex]

Now, we will solve for x. You can use a calculator to do these calculations.

[tex]f=9[/tex]

So, the value of f in the triangle is 9.

Answer:

72.96

Step-by-step explanation:

Let the first circle's radius be r and quarter circle's radius be R

Area of circle = π[tex]r^{2}[/tex]

                       = 3.14 × 8 × 8

                       = 200.96 [tex]cm^{2}[/tex]

Area of quarter circle = π[tex]R^{2}[/tex]/4

                                     = 3.14 × 16 × 16

                                     = 803. 84/4

                                     =200.96

Area of shaded portion = (Area of Quarter circle - Area of semi-circle ACD - Area of triangle ABC) + (Area of the circle -  Area of semi-circle ACD - Area of triangle ABC)

Area of Semi-circle =   Area of the circle divided by 2

                                 = 100.48

Area of triangle = [tex]\frac{bh}{2}[/tex]

                           = [tex]\frac{16 * 8}{2}[/tex]

                           = 64

Therefore, The area of shaded portion= (200.96-100.48-64) + (200.96 - 100.48 - 64)

= 36.48 +36.48

=72.96

Step-by-step explanation:

The slope is (4 - (-2)) / (-1 - 4) = (4 + 2) / (-5) = 6 / -5 = -6/5.

Answer:

-6/5

Step-by-step explanation:

We can find the slope by using the slope formula

Answer:

First investment = $98000

Second = $413,000

Step-by-step explanation:

Given the following :

Investment 1:

Let first investment = f

Rate = 8% = 0.08

Investment 2:

$21,000 more than 4 times of investment 1:

4f + 21000

Rate = 10% = 0.1

Total annual interest earned from both :

$49,140

Interest on investment 1 + interest on investment 2 = $49,140

To solve:

Simple Interest = principal * rate * time

Time = 1 year

Total interest = (f * 0.08 * 1) + ((4f + 21000) * 0.1 * 1)

49140 = 0.08f + 0.4f + 2100

0.48f = 47040

f = 47040 / 0.48

f = 98000 = first investment

Second investment :

4f + 21000

= 4(98000) + 21000

= $413,000

Answer:

[tex]x=-1,5[/tex]

Step-by-step explanation:

[tex]x^2-4x-5=0[/tex]

In order to solve this quadratic, we have many methods. We can factor, complete the square, or use the quadratic formula. I'm going to factor since it's the easiest method.

To factor, find two numbers that when multiplied equal a(c) and when added equal b.

a=1, b=-4, and c=-5.

So we want two numbers that when multiplied equals 1(-5)=-5 and when added equals -4.

-5 and 1 are the possible numbers. Therefore:

[tex]x^2-4x-5=0\\x^2+x-5x-5=0\\x(x+1)-5(x+1)=0\\(x-5)(x+1)=0\\x=5, -1[/tex]

Answer:

The correct option is (D).

Step-by-step explanation:

The two expressions are:

[tex]\text{Exp}_{1}=5x^{2}-2x-4+6x+3\\\\\text{Exp}_{2}=6x^{2}-6x+6-x^{2}+10x-7[/tex]

On simplifying both the expressions we get:

[tex]\text{Exp}_{1}=5x^{2}+4x-1\\\\\text{Exp}_{2}=5x^{2}+4x-1[/tex]

Compute the value of both expressions for x = 2 as follows:

[tex]\text{Exp}_{1}=5(2)^{2}+4(2)-1=27\\\\\text{Exp}_{2}=5(2)^{2}+4(2)-1=27[/tex]

The value of both expressions are same for x = 2.

Thus, the correct option is:

"They are equivalent because when x = 2, the two expressions have the same value."
