Answer:

there are 8 candles

Step-by-step explanation:

(i) In order to obtain an equal amount of candle to candle holders Caroline has to buy enough packs to obtain a 1:1 ratio.

Therefore to obtain a 1:1 ratio:

=30 candles/18 candle holders * (18/30)

Therefore she needs to buy 18 packs of candles and 30 packs of candle holders to have exactly the same number of candles and holders

(ii) Caroline can make = 30*18 = 540 table decorations

What is the slope of the line created by this equation?Round your answer out to two decimal places.3x+5y=7

tia_tia [17]

The given equation is

$3x+5y=7$

Consider the slope-intercept form.

$y=mx+b$

Rewriting the given equation in the slope-intercept form.

$3x+5y=7$

Subtracting 3x from both sides, we get

$3x+5y-3x=7-3x$

Dividing both sides by 5, we get

$\frac{5y}{5}=\frac{7-3x}{5}$ $y=-\frac{3}{5}x+\frac{7}{5}$

$y=-0.6x+1.4$

Compared to the slope-intercept form, we get m=-0.6 and b=1.4.

Hence the slope m= -0.60.

A 7.5 force is applied to a football, causing an acceleration of 15 m/s2. Calculate the mass

faust18 [17]

Step-by-step explanation:

We know that we have the formula that F = ma

Given

Force (F) = 7.5 N

Acceleration (a) = 15 m/s²

Mass (m) = ?

Now

F = ma

7.5 = m * 15

m = 7.5/ 15

Mass = 0.5 kg

30. What is the solution to the system of equations? (1 point)

sesenic [268]

Answer:

Option B) (-1,7,5) is correct.

The solution to the given system of equation is (-1,7,5)

Step-by-step explanation:

Given system of equations are

$-7x-2y+z=-2\hfill (1)$

$6x-y-z=-18\hfill (2)$

$5x+4y-z=18\hfill (3)$

To find the solution of the given system of equations by using Elimination method:

Now adding equations (1) and (2)

$-7x-2y+z=-2$

$6x-y-z=-18$

_________________

$-x-3y=-20$

________________

$-x-3y=-20$

$-(x+3y)=-20$

$x+3y=20\hfill (4)$ (since "-" getting cancelled)

Now adding equations (1) and (3)

$-7x-2y+z=-2$

$5x+4y-z=18$

_________________

$-2x+2y=16$

________________

$-2x+2y=16$

$2(-x+y)=16$

$-x+y=8\hfill (5)$

Now adding equations (4) and (5)

$x+3y=20$

$-x+y=8$

_________________

$4y=28$

________________

$y=\frac{28}{4}$

Therefore y=7

Substituting y=7 in equation (4)

$x+3y=20$

$x+3(7)=20$

$x+21=20$

$x=20-21$

Therefore x=-1

Now substituting the values x=-1 and y=7 in equation (1) we get

$-7x-2y+z=-2$

$-7(-1)-2(7)+z=-2$

$7-14+z=-2$

$z=-2+7$

Therefore z=5

Therefore the solution to the given system of equation is (-1,7,5)

Therefore Option B) (-1,7,5) is correct.

Write 0.000700804 in scientific notation please

klasskru [66]

Multiply the 0.00070080 by 10, 4 times, making it a 7.008. When you multiply each time by 10 it moves the decimal point to the right one time. To keep the number the same you put x10 to the 4th power next to the 7.008. This makes your answer 7.008x10 to the negative 4th power.

Hope I could help! :)
