Sia sells large candles for $3 each and small candles for $2 each. She sold 17 candles for $46.00. How many of each size candle did she sell? 4 small and 13 large candles 5 small and 12 large candles 12 small and 5 large candles 13 small and 4 large candles

Answers

Answer:

The number of large size candles sells are 12 and the number of small size candles are 5 .

Step-by-step explanation:

As given Sia sells large candles for $3 each and small candles for $2 each.She sold 17 candles for $46.00.Let us assume that the large size candle sells are x .Let us assume that the small size candle sells are y.             Equation becomes

x + y = 17

3x + 2y = 46

Multiply x + y = 17 by 3 and subtracted from 3x + 2y = 46 .

3x - 3x + 2y - 3y = 46 - 51

-y = - 5

y = 5

Put in the equation x + y = 17 .

x + 5 = 17

x = 17 - 5

x = 12

Therefore the number of large size candles sells are 12 and the number of small size candles are 5

Isaac paid $81 for a new surfboard. The amount paid was 60% of his total savings. How much money did he have in his savings before buying the surfboard?

Answers

Answer:

$135

Step-by-step explanation:

Given data

Amount paid for new surfboard= $81

Percentage of the savings paid= 60%

Let the amount of the savings be x

Hence

60% of x= 81

60/100*x= 81

0.6x=81

x= 81/0.6

x=$135

Hence his savings was $135

12x−5y=−20 y=x+4 x=x=x, equals y=y=y, equals

Answers

Answer:

The solution is (0, 4)

Step-by-step explanation:

Please pay attention to the first two equations and drop the last two:

12x−5y=−20 y=x+4 x=x=x, equals y=y=y   should ideally be:

12x−5y=−20

y=x+4

Let's find x.  Substitute x + 4 for y in the first equation, obtaining:

12x - 5(x + 4) = -20

Carrying out the indicated multiplication, we get:

12x - 5x - 20 = -20, or 7x = 0

If x = 0 then y must be 0 + 4, or 4.  

The solution is (0, 4)

Answer:x=0 y=4

1,500 people were surveyed and 30 out of every
100 people surveyed have freckles. Based on the
results of this survey, how many people do not
have freckles?

Answers

So since 1,500 people were surveyed and 30/100 have freckles, you would multiply both sides by 15 to get 450 and 1,500. So that means 450 people who took the survey have freckles i believe, so then you would subtract 1,500-450 and you are left with 1,050. The answer should be 1,050.

Answers

Answer:

Pythagorean Theorem = a^2 + b^2= c^2

Step-by-step explanation:

(3)^2+ (4)^2 = C

3^2= 9

4^2= 16

9+16=25

(2 legs no hypotenuse)

9^2+ b^2=7^2

9^2 = 81

7^2= 49

81-49= 32

(you have to sqaure root it because the oppsite of sqaured is sqaured root)

32 squared = 5.657

hopefully this makes sense.

The rotated triangle by 180° counterclockwise about the origin is [tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]

How to rotate the triangle?

The coordinates of the triangle are given as:

The rotation is given as:

180° counterclockwise about the origin.

The rule of 180° counterclockwise about the origin is:

(x,y) ⇒ (-x,-y)

Using the above rule, we have:

[tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]

Hence, the rotated triangle is [tex]\left[\begin{array}{ccc}0&3&-5\\0&-1&-2\end{array}\right][/tex]

Answer:

Circumference = 62.8

Step-by-step explanation:

The equation for discovering a circle's circumference is simple:

-------------------------------------------------------

C = 2πr

C is the circumference (how long is the circle around)

R is the radius (half of the width of the circle)

--------------------------------------------------------

So, instead of giving us the radius, they gave us the diameter. (the full width of the circle) So, we divide that by 2 to get the radius.

20/2=10

Now, time to fill in the equation.

C = 2π10

C = 20π

C = 62.8
