Answer:

Step-by-step explanation:

The lengths of the sides are 7x, 9x, and 12x.

7x + 9x + 12x = 84

28x = 84

x = 3 in

Sides: 21 in, 27 in, 36 in

Write parametric equations of the line through the points (7,1,-5) and (3,4,-2). please use the first point as your base-point w
Roman55 [17]

Given:

A line through the points (7,1,-5) and (3,4,-2).

To find:

The parametric equations of the line.

Solution:

Direction vector for the points (7,1,-5) and (3,4,-2) is

\vec {v}=\left

\vec {v}=\left

\vec {v}=\left

Now, the perimetric equations for initial point (x_0,y_0,z_0) with direction vector \vec{v}=\left, are

x=x_0+at

y=y_0+bt

z=z_0+ct

The initial point is (7,1,-5) and direction vector is \vec {v}=\left. So the perimetric equations are

x=(7)+(-4)t

x=7-4t

Similarly,

y=1+3t

z=-5+3t

Therefore, the required perimetric equations are x=7-4t, y=1+3t and z=-5+3t.

Here are five number cards. 2 5 7 8 9 One of the cards is removed and the mean average of the remaining four number cards is 6.
Lubov Fominskaja [6]

Answer:

Card 7

Step-by-step explanation:

2+5+7+8+9 =31

Multiples of 6: 6, 12, 18, 24, 30

31-9=22, No

31-8=23, No

31-5=26, No

31-2=29, No

31-7=24, Yes

The only way to get a multiple of 6 is to subtract card 7, so card 7 is the answer.

5•10^6 is how many times as large as 5•10^6
Mamont248 [21]

Answer: 100

Step-by-step explanation:

For any two numbers X and Y, you can figure out how many times larger X is than Y by dividing X by Y . For example , 8 is 4 fine larger than 2 because 8/2=4 5*10^6/5*10^4 = 5/5*10^6/10^4 = 1*10^2 = 100

You went shopping last weekend and bought a new shirt. The shirt had an original price of $39.00 but it was on sale for 35% off
balandron [24]

Answer:

$26.87

Step-by-step explanation:

if the shirt was 35% off, then you paid 65% of the cost

that value can be found by:

39 x .65 = 25.35 (this is the amount paid for the shirt)

sales tax of 6% on 25.35 is:

.06 x 25.35 which equals 1.52

25.35 + 1.52 = 26.87
