Answer:

x=7.96

Step-by-step explanation:

We need to use the law of sines

sin 60 sin 80

---------- = ---------------

7 x

Using cross products

x sin 60 = 7 sin 80

x = 7 sin 80 / sin 60

x=7.96010

To the nearest hundredth

x = 7.96

Three girls cut out decimal models of hundredths. Amber doesn't shade any of her models. Grace qualifies three fifths of a model

Varvara68 [4.7K]

Answer:

$Amber = 0$

$Grace = 0.60$

$Marsha =1.70$

Step-by-step explanation:

Given

<em>Decimal Grid = Hundredths</em>

$Amber = None$

$Grace = \frac{3}{5}th$

$Marsha = 1 + \frac{7}{10}th$

To solve for each:

We have:

For Amber:

$Amber = 0 * 100$

$Amber = 0$

For Grace:

$Grace = \frac{3}{5}th$

$Grace = \frac{3}{5} * 100$

$Grace = \frac{300}{5}$

$Grace = 60$

This means that Grace shaded 60 of the hundredth models.

Decimal shaded is:

$Grace = 60 * \frac{1}{100}$

$Grace =\frac{60}{100}$

$Grace = 0.60$

For Marsha:

$Marsha = 1 + \frac{7}{10}th$

$Marsha = \frac{10 + 7}{10}th$

$Marsha = \frac{17}{10}th$

$Marsha = 1.7th$

Multiply this by 100, to get the number of shaded

$Marsha = 1.7 * 100$

$Marsha = 170$

This means that Marsha shaded 170 of the hundredth models.

Decimal shaded is:

$Marsha = \frac{170}{100}$

$Marsha =1.70$

Find the slope of the line that passes through the points (0, -3) and (-4,1).

kozerog [31]

The formula for slope is $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

In this case:

$y_{2} = 1\\ y_{1} }= -3\\x_{2} = -4\\x_{1} = 0$

so...

$\frac{1 - (-3)}{-4 - 0}$

$\frac{4}{-4}$

-1 <<<The slope

Hope this helped!

PQRS is a parallelogram with PQ=26cm and QR=20cm . If the distance between the longer-sides is 12.5cm , Find

Kay [80]

Answer:

Below.

Step-by-step explanation:

I am guessing you want the area of the parallelogram.

Take the longer side to be the base.

Area = base * distance between base and opposite side

= 26 * 12.5

= 325 cm^2.
