Answer:

A. the $5 off coupon

Step-by-step explanation:

10% off would only be 2.99 off the bill making it 26.91 but the $5 would take off more

The coupon I would use to save the most amount of money on the total bill is my friend's coupon worth $5.

Coupons reduce the price of an item. An item becomes cheaper after a coupon has been used. In order to determine the better coupon, calculate the price after each coupon has been used.

Coupon 1 : 10% x 29.9 = $3

Coupon 2 : 29.90 - $5 = $24.90

Answer:

2/5=0.4=40%

Step-by-step explanation:

because if you divide 2/5 you'll get 0.4.  if you want to put that in a percent you'll multiply 0.4 and 100 and you should get 40%.

Answer:

I suppose we want to find the side length of the square.

We know that:

The area of the square is 49cm^2

The distance between one of the vertices of the square and the middle of the square is:

BE = 4.95cm

Now let's remember some things.

For a square of side length L, the area is:

A = L^2

and the diagonal length is:

D = √(2)*L

In this case, we know that half of the diagonal is equal to:

BE = 4.95 cm

Then the diagonal is:

D = 2*BE = 2*4.95cm = 9.9cm

And for the diagonal formula, we have:

D =  9.9cm = √(2)*L

Then the side length is:

L = 9.9cm/√(2) = 7cm

And if we check the area of this square, is:

A = L^2 = (7cm)^2 = 49cm^2

So it checks.

Then we can conclude that the sidelength of the square is 7cm, which means that:

AB = 7cm

BC = 7cm

CD = 7cm

DA = 7cm

Answer:

6 units

Step-by-step explanation:

The formula for calculating the distance between two points is expressed as;

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

Given the coordinate points  E=(-6,8) and N=(-1,5)

[tex]EN = \sqrt{(5-8)^2+(-1+6)^2}\\EN = \sqrt{(-3)^2+(5)^2}\\EN = \sqrt{9+25}\\EN = \sqrt{34}\\EN = 5.8\\EN \approx 6[/tex]

Hence the distance between the points is approximately 6 units

Answer:

[tex] \sqrt{125 } \\ = 11.18[/tex]

It is in between 0 to 12.

Answer:

√125 must be between 11 and 12.

Step-by-step explanation:

Identify perfect squares in the neighborhood of 125:  

121 = 11^2      or      √121 = 11

144 = 12^2               √144 = 12

√125 must therefore be between 11 and 12.

Answer:

240 cm^3

Step-by-step explanation:

The solid is composed by two rectangular parallelepipeds. To find the total volume  we have to find the volume of the two solids and added up.

To find the volume of a parallelepiped we have to use this formula:

V = base surface x height

The area of rectangle is : base x width

So:

Area first rectangle: 4 x 6 = 24 cm^2

V = 24 x 7 = 168 cm^3

Area second rectangle: 4 x 2 = 8 cm^2

V = 8 x 9 = 72 cm^3

total volume = 168 + 72 = 240 cm^3

Answer:

360 approx

Step-by-step explanation:

Given data

We want to find the total number of customers that bought gas

Let the total number of customers be x

So

72% of x = 259

let us solve for x

72/100*x= 259

0.72*x=259

x= 259/0.72

x= 359.72

Hence the actual number of customers is 360 approx

Answer:  

No Ada is not correct  

Step-by-Step Explanation:  

The length of diagonal SQ is not two times the length of diagonal OM. When you split the rectangle using the diagonal you can make a right triangle and use the Pythagorean Theorem to the rest of it.  

This would be the Rectangle:  

a^2+b^2=c^2  

8^2+16^2=c^2  

64+256+c^2  

320=c^2  

√320  

17.8

This would be the Square:  

a^2+b^2=c^2  

8^2+8^2=c^2  

64+64=c^2  

128=c^2  

√128

11.3

Now when I divide these answers that I came up with I get 1.7 which is not equal to 2 therefore SQ is not two times bigger than OM.

Answer:

Step-by-step explanation:

x is the number of miles driven, and I'm assuming that's supposed to say that he plans on driving 500 miles per day and has $210 to spend. We need a cost equation for his trip. $68.64 is the flat fee the company charges regardless of how many miles, x, are driven. If they charge $.12 per mile, that's the rate per mile of the equation which is the same thing as the slope of the linear equation. The cost equation is

y = .12x + 68.64

If he has $210 to spend, let's see how many miles he can go on that by subbing in 210 for y:

210 = .12x + 68.64 and

141.36 = .12x so

x = 1178

He can drive a total of 1178 miles with $210. If he drives 500 miles per day, 1178/500 = 2.356 days. So depending upon when he has to return the car and assuming it's in the morning, he can keep the car for 2 full days and stay within his budget.

Answer:

tanA=BC/AC

BC=20

AC=48

so,BC/AC=20/48=5/12

Answer:

According to the theorem of chords intersecting inside the circle,

1) 15 * 8 = 10 * x

120 = 10x

120/10 = x

12 = x

2) 21 * 10 = 14 * x

210 = 14 x

210/14 = x

15 = x

3)10 * 4 = 5x

40 = 5x

40/5 = x

8 = x

4) 5x * 2x = 10*9

10x^2 = 90

x^2 = 90/10

x^2 = 9

x = √9

x = 3

5)3x + 3 * 3x = 10 * 18

9 x^2 + 9x = 180

dividing the whole eq. by 9

x^2 + x = 20

x^2 + x - 20 = 0

x^2 + 5x - 4x - 20 = 0

x(x + 5) - 4(x + 5) = 0

x - 4 = 0 OR x + 5 = 0

x = 4 or x = -5

The length cannot be negative, so,

x = 4
