Mark has twice as much money as Tamassa. Together they have $630. How much money does Mark have

Mark has $472.5

630/2= 315 (shared equally)
But 315/2= 157.5
315+157.5= 472.5 (mark)
472.5/2= 157.5

Mark has $472.5
Tamassa has 157.5
All together (472.5+157.5) = $630

NEED HELP! PLEASE! geometry questions (4) 15 points!

mixer [17]

Answer:

1. 617.5 cm³

2. 335.6 in³

3. 151.6 m³

4. 3479.1 ft³

Step-by-step explanation:

B1: 19.5 × 9 = 175.5

B2: 6 × 13 = 78

sqrt(B1 ×B2) = 117

h = 5

Volume = ⅓ × 5 × [175.5 + 78 + 117]

617.5

B1: 3.14 × 4.5² = 63.585

B2: 3.14 × 3² = 28.26

sqrt(B1 ×B2) = 42.39

h = 7.5

Volume = ⅓ × 7.5 × [63.585 + 28.26 + 42.39]

335.5875

B1: ½(8+12) × 6 = 60

B2: ½(3+4.5) × 2.25 = 8.4375

sqrt(B1 ×B2) = 22.5

h = 5

Volume = ⅓ × 5 × [60 + 8.4364 + 22.5]

151.5625

B1: 3.14 × 12² = 452.16

B2: 3.14 × 7² = 153.86

sqrt(B1 ×B2) = 263.76

h² = 13² - (12-7)²

h² = 13² - 5²

h² = 144

h = 12

Volume = ⅓ × 12 × [452.16 + 153.86 + 263.76]

3479.12

A line passes through the points (2,4) and (-4,-1). Find its equation in slope-intercept form. (2 points, 1 for work, 1 for equa

vovangra [49]

<h2>Hello!</h2>

The answer is:

The equation of the line in slope-intercept form:

$y=\frac{5}{6}x+\frac{7}{3}$

To find the equation in slope-intercept form, we need to follow the next steps:

Find the slope of the line:

Using the slope formula, we have:

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

We are given the points:

$(2,4)\\(-4,-1)$

So, substituting we have:

$m=\frac{(-1)-(4)}{-4-2}$

$m=\frac{-5}{-6}$

$m=\frac{5}{6}$

Find the "b" value:

Now that we know the value of the slope, we can write the equation of the line:

$y=\frac{5}{6}x+b$

In order to find "b" we need to substituite any of the given points, we know that line is thru both of the given points, so, substituting (2,4) we have:

$4=\frac{5}{6}*2+b\\\\4=\frac{10}{6}+b\\\\4=\frac{5}{3}+b\\\\b=4-\frac{5}{3}=\frac{(3*4)-5}3}=\frac{12-5}{3}=\frac{7}{3}$

Now that we know the slope and "b", we can write the equation of the line in slope-intercept form:

$y=\frac{5}{6}x+\frac{7}{3}$

Have a nice day!
