T = large candles and s = small candles

3t + 5s = 6.40
4t + 6s = 7.50

^^ this would be ur system of equations

Answer:

3t + 5s = 6.40

4t + 6s = 7.50

These two equations can be used to determine, t, the cost of a large candle, and s, the cost of a small candle.

Step-by-step explanation:

Let the the letters  t represents the cost of a large candle, and s represents the cost of a small candle.

The cost of 3 large candles and 5 small candles is $6.40

          3t + 5s = 6.40

The cost of 4 large candles and 6 small candles is $7.50

          4t + 6s = 7.50

These two equations can be used to determine, t, the cost of a large candle, and s, the cost of a small candle.

Answer:

NI = 45

IG=28

HG^2 = NI^2 +IG^2

= 45^2 +28^2

=2025+784

= 2809

HG=53

CosG = IG/HG

= 28/53

= 0.52

Perform the indicated operation. 10 3/7 + 19 5/9
DanielleElmas [232]
Given expression is

10 \frac{3}{7} + 19 \frac{5}{9}

Now convert mixed fraction as improper fraction as

10 \frac{3}{7} + 19 \frac{5}{9} =  \frac{10*7 + 3}{7} +  \frac{19*9+5}{9}
                                                         =  \frac{73}{7}  +  \frac{176}{9}
                                                          =  \frac{73*9 + 176 * 7}{63}
                                                         =  \frac{657 + 1232}{63} =  \frac{1889}{63}
Now we can convert \frac{1889}{63 } = 29 \frac{62}{63}

So the answer is 29 \frac{62}63}

Saul decides to use the IQR to measure the spread of the data. Saul calculates the IQR of the data set to be 27.
padilas [110]

Answer:

78

Step-by-step explanation:

The IQR is quartile 3 - quartile 1. First, we need to find the mean of the dataset, which is 50 -- the fifth number. Then, the median of the dataset on the left of the fifth number is the first quartile, and the median of the dataset on the right is the third. We get Q1 to then be halfway between 30 and 50, or 40, and Q3 to be halfway between 56 and n, so Q3 = (56+n)/2. Since we need Q3-Q1=27, or (56+n)/2-40=27, we have (56+n)/2=67 and 56+n=134, so n = 134-56=78

Find m∠DEC (the picture is not drawn to scale).
pochemuha

Answer:

M∠DEC equals 123º.

Step-by-step explanation:

The sum of a triangle's three angles always equal 180º. The exterior angle, x, equals the two non-adjacent interior angles.

180 - {(x - 45)+(x - 12)} = m∠DEC

m∠DEC + x = 180

<u>(x - 45) + (x - 12) = x</u>

Solving for x:

(x - 45) + (x - 12) = x

x - 45 + x - 12 = x                             Remove parenthesis

2x - 57 = x                                       Combine like terms

2x = x + 57                                      Add 57 to both sides

<u>x = 57</u><u>                                             Subtract x from both sides</u>

Finding m∠D:

x - 45 = ?

<u>57 - 45 = </u><u>12º                                          </u>

Finding m∠C:

x - 12 = ?

<u>57 - 12 = </u><u>45º                                           </u>

<em>** </em><em>(Checking x: 12 + 45 = 57) </em><em>**</em>

<em>Finding </em>m∠DEC:

AC is a straight line, and because straight lines are equivalent to 180º, we subtract 57 from 180:

180 - 57 = 123º

Hope this helps,
