Answer:

14.4 miles

Step-by-step explanation:

Given that :

Distance moved North = 12 miles

Distance moved West = 8 miles

Shortest distance to reach starting point :

Let shortest distance to reach starting point = d miles

Using the relation :

Longest side of a right angled triangle:

d = sqrt(8^2 + 12^2)

d = sqrt(64 + 144)

d = sqrt(208)

d = 14.422205

d = 14.4 miles (nearest tenth of a mile)

Answer:

[tex]\boxed{26}[/tex]

.

Step-by-step explanation:

First step, find the value of tilted line. use pythagoras

[tex]c^2 = a^2 + b^2[/tex]

[tex]c^2 = 3^2 + 4^2[/tex]

[tex]c^2 = 9 + 16[/tex]

[tex]c^2 = 25[/tex]

[tex]c = \sqrt{25}[/tex]

[tex]c = 5[/tex]

.

So, the primeter is

[tex]= 2(5) + 4 + 12[/tex]

[tex]= 26[/tex]

Answer:

c is the correct answer i my guest

Answer:

no

Step-by-step explanation:

here, f (x)=x^3 - 4x^2 + 3x + 7

when, factor is (x + 5)

x - a =x + 5

a = -5

Reminder= f (a)

= (-5)^3 - 4 (-5)^2 + 3×(-5) + 7

= -233

Since Reminder = -233 which is not 0 .

(x + 5) is not a factor of f (x)=x3-4x2+3x+7

Answer:

4 ...................

The requried multiplication of 1/2 and 1/2 is equal to 1/4. This means that if you divide a whole into 4 equal parts and then take one of those parts.

To multiply fractions, you simply multiply the numerators together and the denominators together.

The multiplication of 1/2 and 1/2 is calculated as follows:

(1/2) * (1/2) = (1 * 1) / (2 * 2)
                = 1 / 4

Therefore, the multiplication of 1/2 and 1/2 is equal to 1/4. This means that if you divide a whole into 4 equal parts and then take one of those parts, it's equivalent to multiplying 1/2 by 1/2.

Answer:

Least no of packs = 120

Step-by-step explanation:

Given that,

Plastic plates come in packs of 8, plastic utensils come in packs of 12, and plastic cups come in packs of 20.

We need to find least numbers of packs you should buy in order to have the same number of plates, utensils, and cups.

It means we need to find the LCM of 8,12,20

Prime factorisation of 8 = 2×2×2

Prime factorisation of 12 = 2×3×2

Prime factorisation of 20=2×5×2

LCM = 120

Hence, there are 120 least number of packs you should buy in order to have the same number of plates, utensils, and cups

Answer:

166.67 pounds

Step-by-step explanation:

Set up a proportion where x is Tom's weight in pounds:

[tex]\frac{75}{x}[/tex] = [tex]\frac{0.45}{1}[/tex]

Cross multiply and solve for x:

75 = 0.45x

166.67 = x

So, Tom weighs approximately 166.67 pounds

Answer:

Option a is "False".

Option b is "True".

Step-by-step explanation:

In point a:

Prove AB=BA

[tex]A=\left[\begin{array}{cc}1&2\\4&5\end{array}\right] \\\\B= \left[\begin{array}{cc}2&1\\8&5\end{array}\right][/tex]

Solve L.H.S part:

[tex]AB= \left[\begin{array}{cc}1&2\\4&5\end{array}\right] \times \left[\begin{array}{cc}2&1\\8&5\end{array}\right][/tex]

      [tex]= \left[\begin{array}{cc}2+16 &1+10\\8+40&4+25\end{array}\right]\\\\\\= \left[\begin{array}{cc}18 &11\\48&29\end{array}\right][/tex]

Solve R.H.S part:

[tex]BA= \left[\begin{array}{cc}2&1\\8&5\end{array}\right] \times \left[\begin{array}{cc}1&2\\4&5\end{array}\right][/tex]

      [tex]= \left[\begin{array}{cc}2+4 &4+5\\8+20&16+25\end{array}\right]\\ \\ \\= \left[\begin{array}{cc}6 &9\\28&41\end{array}\right][/tex]

So, [tex]AB \neq BA[/tex]

In point b:

[tex]A^{*} =A\\\\(Ak)^{*} =A^k[/tex]

if [tex]k= 1[/tex]it holds the trivially [tex]A^{*}=A ...........(1)[/tex]

by assuming that if it is true for [tex]k=n-1[/tex]

that is

[tex](A^{n-1})^{*}= A^{n-1}............(2) \\\\ if \ k=n\\\\\to (A^{n})^{*} = (A^{n-1} \cdot A^1)^{*} = A^{*}(A^{n-1})^{*} \\\\\to A(A)^{n-1}[/tex] use above equations

[tex]\to A^{n-1+1} \\\\ \to A^{n}[/tex]

that's why it is true.

Answer: Though no choices of statements are shown, you can predict that x+2=-3, since both numbers are equal to y. (This isn't really an answer but I hope it'll at least help you in some way!)

-By subtracting 2 on both sides, you end up with x=-5. So in both equations, y is -3 and x is -5.

-The point where they intersect is (5,-3)

Answer:

Devon

Step-by-step explanation:

lets use t=1 to compare

1. -5(12t+9)

if t = 1, -5(12+9) = -5(21) = negative number

2. 2(-6t-8)

if t = 1, 2(-6-8) = 2(-14) = negative number

3. -6(-2t+18)

if t = 1, -6(-2+18) = -6(16) = negative number

4. (-4(-3t-2)

if t = 1, -4(-3-2) = -4(-5) = 20 positive number
