Answer:

Step-by-step explanation:

amount of discount = $10

percentage discount = $10/$39.99 ≅ 0.25 = 25%

amount of sales tax = $1.95

sales tax rate = $1.95/$29.99 ≅ 0.065 = 6.5%

cost of jeans × 1.60 = $39.99

cost of jeans = $39.99/1.60 ≅ $24.99

discounted selling price = $29.99

markup = $29.99/$24.99 ≅ 1.20 = 20%

Answer:

The smaller ship is 1,164 ft

The larger ship is 1,177 ft

The larger ship is 3.923 football fields

Step-by-step explanation:

A. Find the length of each ship

x + x + 13 = 2,341 ft

2x + 13 = 2,341 ft

2x = 2,328 ft

x = 2,328/2

x = 1,164 ft ( This is the length of the smaller ship)

1,164 + 13 = 1,177 ft (length of the larger ship)

B)If a football field has a length of 100 yards, determine the length of the longer ship in terms of football fields.

1,177/3ft= 392.3 yards

392.3 yards /100 yards = 3.923 football fields

Answer:

276 meters in the first 2 hours

Step-by-step explanation:

Given that,

Professional climbers climb 828 meters in 6 hours.

Let us assume we need to find how far did they climb in the first 2 hours.

6 hours = 828 m

⇒ 1 hour = 138 m

So, in 2 hours,

2 hours = 138 × 2 m

= 276 m

So, the climber climb 276 meters in the first 2 hours

I say the answer would be No because the triangles are not the same Width, length or height..

Answer:

Jamie's tickets = $187.48

Step-by-step explanation:

The amount for which Amanda bought tickets = $218

Jamie bought tickets to the same concert but paid 14% less than Amanda.

Jamie's tickets = [tex]218-14\%\ of\ 218[/tex]

We can solve it as follows :

[tex]218-14\%\ of\ 218=218-\dfrac{14}{100}\times 218\\\\=218-30.52\\\\=\$187.48[/tex]

So, the price of Jamie's tickets is $187.48.

Answer:

y = 5/2x + 5

y = -1/2x + 11

Step-by-step explanation:

5x -2y = -10

-2y = - 5x -10

y = 5/2x + 5

3x + 6y = 66

6y = -3x + 66

y = -1/2x + 11

Answer:

D (last one), [tex]x^2+y^2=45[/tex]

Step-by-step explanation:

We need to find the distance between (0,0) and (-3,6). Using the distance formula we get:

[tex]d=\sqrt{\left(x_2-x_1\right)^2+\left(y_2-y_1\right)^2}[/tex]

[tex]d=\sqrt{\left(-3-0\right)^2+\left(6-0\right)^2}[/tex]

[tex]d=3\sqrt{5}[/tex]

Since equation of circle is: [tex]x^2+y^2=r^2[/tex] we have to square the distance we just found, which gives us 45.

Answer:

x^2 + y^2 = 45

Step-by-step explanation:

(x − a ) ^2 + ( y − b ) ^2 =r^2

= (-3-0)^(2)+(6-0)^(2)

=45

Answer:

Option 2 (open circle at 6 with arrow going to the right.

Step-by-step explanation:

Open circle means "excluding that number". Since x>6, x cannot be 6 so we have an open circle at 6. x>6 also means x has to be greater than 6, so we have the arrow going to the right since 7 is greater than 6, 8 is greater than 6, and so on so forth.

x=13.33

Step-by-step explanation:

4/x=(4+3)/(x+=10)  this is the ratio

4(x+10)=(3+4)(x)

4x+40=7x

4x-4x+40=7x-4x

3x=40

x=13.33

Answer:

he would have bought 6 5/6 pounds of rice.

Step-by-step explanation:

4 1/2 + 2 1/3 = ?

First, you want to get common dominaters. And the closest number is 6

4 3/6 + 2 2/6 = 6 5/6

This can not be simplifyed so that would be your answer.

The total weight, in pounds, of rice purchased by Marcus in the two-day period is [tex]6\frac{5}{6}[/tex] pounds.

It is given that,

Amount of rice purchased on Monday = [tex]4\frac{1}{2} pounds[/tex]

Amount of rice purchased on Tuesday[tex]=2\frac{1}{3} pounds[/tex]

the total weight, in pounds, of rice purchased by Marcus in the two-day period is computed as;

                            [tex]=4\frac{1}{2}+2\frac{1}{3} \\\\=\frac{9}{2} +\frac{7}{3} \\\\=\frac{27+14}{6} \\\\=\frac{41}{6}\\ \\=6\frac{5}{6} pounds[/tex]

Therefore, the total weight of rice is [tex]6\frac{5}{6}[/tex] pounds.

Answer:

Unit rate: 13 sit ups per minute

65 sit ups can be done in 5 minutes

Step-by-step explanation:

Find the unit rate by dividing 26 by 2

26/2

= 13

This means 13 sit ups can be done in 1 minute.

To find how many can be done in 5 minutes, multiply 13 by 5.

13(5)

= 65

So, the unit rate is 13 sit ups per minute, and 65 sit ups can be done in 5 minutes.

Answer:

  7√2

Step-by-step explanation:

The triangle is a "special triangle", an isosceles right triangle. The side lengths of this triangle have the ratios 1 : 1 : √2. Multiplying these ratio values by 7, the length of the leg, you find ...

  c = 7×√2

  c = 7√2

_____

If you like, you can go through the Pythagorean theorem and/or trigonometry to find the same thing.

  7/c = sin(45°)

  c = 7/sin(45°) = 7/(1/√2) = 7√2

Or ...

  c² = 7² + 7² = 98 . . . . using the Pythagorean theorem*

  c = √98 = 7√2

__

* This requires you recognize the triangle is isosceles, so the other leg is also 7. Of course, you know that as soon as you see a 45° acute angle in a right triangle.

Answer:

Zero solutions; there are no variables and thus there are no solutions

Step-by-step explanation:

We start out with the equation 9 (x - 3) + 15 = 9x - 11

Which simplifies to 9x - 27 + 15 = 9x - 11

The 9x terms cancel each other out, and we're left with 15 - 27 = -11

And we end up with -12 = -11, which is not true.

This tells us that the equation has zero solutions, because no matter what value we substitute for x, the equation will not be true.

Answer:

No solution

Step-by-step explanation:

9(x-3)+15= 9x-11

9x-27+15=9x-11

-15 on both sides

9x-27=9x-26

add 26 on both sides

9x -1=9x

add 1 on both sides

9x=9x+1

divide 9 on both sides

x=x+1/9

No solution
