Sami lights up a candle every 10 minutes. Every candle burns for exactly 40 minutes. How many candles are burning exactly 55 minutes after Sami lit up the first candle?

Answers

Answer:

Step-by-step explanation:

Candle is lit every 10 minutes :

Number of candles lit in 55 minutes:

Starting from 0 minute ; Numbe rod candles lit on 55 minutes = 6

1st candle burns out after 40 minutes

Second burns out after 50 minutes

Third will burn out after 60 minutes

Hence Number of candles still burning :

Number of candles lit - Number of candle burnt out

6 - 2 = 4 candles

Answers

Answer:

1 1/3 miles

Step-by-step explanation:

1/3 is for a half-mile, so double it to 2/3 for one mile.

Now double it again for two hours.

2/3 + 2/3 = 1 1/3 miles in two hours

Answer:

The person will walk 1 1/3 miles in 2 hours.

Step-by-step explanation:

There are 4 half-hours in 2 hour

Circle D is shown. Line segment F E goes through point D. Line segment C D is shown. Line segment G H goes from one side of the circle to the other side. Line segment A B is outside of the circle and intersects the circle at point B.
In circle D, which is a secant?

EF
DC
Line segment A B
Line G H

Answers

A secant crosses the circle without passing through the center

The secant line is (c) line segment AB

How to determine the secant line

From the question, we understand that line segment AB passes through the circle, without passing through the center (i.e. point A) of the circle

This indicates that line segment AB is a secant

Given that the center of the circle is point D

Hence, the secant line is (c) line segment AB

Show set of data that is a function using at least 5 domain values and 5 range values. It can be shown in a format of your choice

Answers

Answer:

Five domain values of the function f(x) = x² - 1, are; 1, 2, 3, 4, 5

Five range values of the function f(x) = x² - 1, are; 0, 3, 8, 15, 24

Step-by-step explanation:

The values in the domain are the values of the independent or (normally) x-variable

The values i the range are the values obtained by applying the function relationship to the domain as follows;

Let 'f(x)' represent the function that generates the values of the data in the data set,

For f(x) = x² - 1, we have the following table;

[tex]\begin{array}{ccc}x&f(x)\\1&0\\2&3\\3&8\\4&15\\5&24\end{array}[/tex]

Therefore;

The function is f(x) = x² - 1

The five domain values are; 1, 2, 3, 4, 5

The five range values are; 0, 3, 8, 15, 24.

Samaia buys two water bottles and three bags of chips for $9.45. Abdullah goes to the same store and buys four water bottles, as Samaia, and five bags of chips, same as ones Samaia bought, for $14.75. Which choice below accurately represents a system of equations, w for water bottles and c for chips, for this scenario? Each water bottle is same price and each bag of chips is same price. * A) 3w + 2c = 9.45 AND 5w + 4c = 14.75 B) 2w + 3c = 9.45 AND 4w + 5c = 14.75 3) 2w + 3c = 14.75 AND 4w + 5c = 9.45 D) 5c + 9w = $24.20

Answers

Answer:

B) 2w + 3c = 9.45 AND 4w + 5c = 14.75

Step-by-step explanation:

Let us represent:

Number of water bottles = w

Number of bag of chips = c

Hence:

Samaia buys two water bottles and three bags of chips for $9.45.

2w + 3c = 9.45......Equation 1

Abdullah goes to the same store and buys four water bottles, as Samaia, and five bags of chips, same as ones Samaia bought, for $14.75.

4w + 5c = 14.75......Equation 2

Which choice below accurately represents a system of equations, w for water bottles and c for chips, for this scenario?

Option B) 2w + 3c = 9.45 AND 4w + 5c = 14.75 is the correct option.

There is a sale on Blu-rays in a local shop – 20% off selected items. Your favorite Blu-ray before the sale cost $18. How much will you save? How much will you pay?

Answers

Answer:

save $3.6, pay $14.4

Step-by-step explanation:

A cd costs $18

If there is a 20% discount, you only have to pay 80% of the original price.

This means you only have to pay (0.80 x $18=) $14.4 dollars, which means you saved ($18 - $14.4=) $3.6.

Or you could just do $18 x 0.20 = $3.6

How many degrees are on
the interior of a Polygon that
has 18 sides?

Answers

Answer:

ask yourself

Step-by-step explanation:

Answer:

160.00° Degrees

Step-by-step explanation:

To find the answer, we have to use the interior angle formula which is

(n-2)*180, where n is the number of sides. This formula gives us the sum of all interior angles in a polygon having ‘n’ sides.

For a polygon with 18 equal sides, first finding the sum of all interior angles of the polygon:-

=(n-2)*180= (18–2)*180=16*180=2880 degree.

We found the sum of all interior angles of 18 sided polygon and it is 2880 degrees.

The polygon we are considering has all sides equal, which means it is a regular polygon. So we can conclude that all of its interior angles are equal.

Sum of all eighteen angles=2880, One angle=2880/18=160 degrees.

Thus, we concluded that the interior angle of the regular eighteen sided polygon

is 160 degrees

Check whether -2 is a zero of the polynomial 3x2 + 4x + 32 .

Answers

Answer:

x = - 2 is not a zero

Step-by-step explanation:

If x = - 2 is a zero of the polynomial then f(- 2) = 0

f(x) = 3x² +4x + 32

f(- 2) = 3(- 2)² + 4(- 2) + 32 = 3(4) - 8 + 32 = 12 - 8 + 32 = 36

Since f(- 2) ≠ 0 , then x = - 2 is not a zero of the polynomial

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Variables

Stuffed bears = b

Stuffed dogs = d

Step 2: Define Systems

$7b + $8d = $3800

b + d = 500

Step 3: Rewrite Systems

b + d = 500

[Equality Property] Multiply everything by -7: -7b - 7d = -3500

Step 4: Redefine Systems

7b + 8d = 3800

-7b - 7d = -3500

Step 5: Solve for d

Elimination

Combine 2 equations: d = 300

Step 6: Define Answer

d = 300 means that the students bought 300 stuffed dogs.

Answer:

Step-by-step explanation:

Remark

Let the stuffed bear = x

Let the stuffed dog = y

Equations

x + y = 500 (1)

7x + 8y = 3800 (2)

Solution

There are two ways you could do this. You can use substitution or you could use multiplying equation 1 by either 7 or 8 to get rid of the x or y.

Multiply (1) by 7

7x + 7y = 3500 (3) Write equation (2) below (3) and subtract

7x + 8y = 3800 Subtract

-y = - 300 Multiply by - 1

y = 300

Use the result for y to get x using equation 1

x + y = 500

x + 300 = 500 Subtract 300

x = 500 - 300

x = 200

Stuffed bears = 200

Stuffed dogs = 300
