The label on the car's antifreeze container claims to protect the car between −30°C and 130°C. To convert Celsius temperature to

Sveta_85 [38]

we know that

$C = \frac{5}{9}(F-32)\\ \\F=\frac{9}{5}C+32$

Step $1$

<u>Find the inequality</u>

we know that

$C = \frac{5}{9}(F-32)$ --------> equation $1$

and

$-30\° < C < 130\°$

substitute the equation $1$ in the inequality

$-30\° < \frac{5}{9}(F-32) < 130\°$

Step $2$

<u>Convert $-30\°C$ to F</u>

substitute in the formula

$F=\frac{9}{5}*(-30)+32\\ \\F= -22\°$

Step $3$

<u>Convert $130\°C$ to F</u>

substitute in the formula

$F=\frac{9}{5}*(130)+32\\ \\F= 266\°$

therefore

$-22\° < F < 266\°$

the answer is the option

B. −30 < 5 over 9 (F − 32) < 130; −22 < F < 266

Answer:

36.5 inches

Step-by-step explanation:

Given

See attachment for the given data

Required

Which length is closest to 4.2lb

The given data is a linear dataset.

So, we start by calculating the slope (m)

$m =\frac{y_2 - y_1}{x_2 - x_1}$

Pick any two corresponding points from the table

So, we have:

$(x_1,y_1) = (8,1.21)$

$(x_2,y_2) = (12,1.63)$

So:

$m =\frac{y_2 - y_1}{x_2 - x_1}$

$m =\frac{1.63 - 1.21}{12 - 8}$

$m =\frac{0.42}{4}$

$m =0.105$

The linear equation is then calculated using:

$y = m(x - x_1) + y_1$

This gives:

$y = 0.105 * (x - 8) + 1.21$

Open bracket

$y = 0.105x - 0.84 + 1.21$

$y = 0.105x + 0.37$

To get the length closest to 4.2lb,

we set $y = 4.2$

Then solve for x

So, we have:

$y = 0.105x + 0.37$

$4.2 = 0.105x + 0.37$

Collect like terms

$0.105x= 4.2 - 0.37$

$0.105x= 3.83$

Solve for x

$x= 3.83/0.105$

$x\approx 36.5$

Jinni opened a bank account. she deposited $87.60 into her account every month for 10 months. she used $25.60 every month to pay

LuckyWell [14K]

Amount left in account after paying for music class = $87.60 - $25.60 = $62
Amount in the bank account after 10 months = $62 x 10 = $620
Amount spent to go to the summer camp = 1/4 x $620 = $155
