Answer:

204

Step-by-step explanation:

Answer:

204

Step-by-step explanation:

Given the following question:

[tex]10\frac{2}{3} \times3\times6\frac{3}{8}[/tex]

In order to solve we will convert the mixed numbers into improper fractions and then solve by multiplying the numerators by the numerators and multiplying the denominators by the denominators.

[tex]10\frac{2}{3} \times3\times6\frac{3}{8}[/tex]
[tex]10\frac{2}{3} \times3[/tex]
[tex]10\frac{2}{3} =3\times10=30+2=32=\frac{32}{3}[/tex]

[tex]3=\frac{3}{1}[/tex]

[tex]\frac{32}{3} \times\frac{3}{1}[/tex]
[tex]32\times3=96[/tex]
[tex]3\times1=3[/tex]
[tex]=\frac{96}{3}[/tex]

[tex]\frac{96}{3}\times6\frac{3}{8}[/tex]
[tex]6\frac{3}{8} =8\times6=48+3=51=\frac{51}{8}[/tex]
[tex]\frac{96}{3}\times\frac{51}{8}[/tex]
[tex]96\times51=4896[/tex]
[tex]3\times8=24[/tex]
[tex]=\frac{4986}{24}[/tex]

Simplify by reducing:
[tex]=\frac{4986}{24}\div2=\frac{2493}{12}[/tex]
[tex]=\frac{2493}{12}[/tex]
[tex]\frac{2493}{12}[/tex]
[tex]=\frac{2493}{12}=2493\div12=204[/tex]
[tex]=204[/tex]

Your answer is indeed "204."

Hope this helps.

Answer:

r = 7

Step-by-step explanation:

Calculate the slope using the slope formula then equate to - [tex]\frac{1}{4}[/tex]

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (- 6, r ) and (x₂, y₂ ) = (2, 5 )

m = [tex]\frac{5-r}{2-(-6)}[/tex] = [tex]\frac{5-r}{2+6}[/tex] = [tex]\frac{5-r}{8}[/tex] , then

[tex]\frac{5-r}{8}[/tex] = - [tex]\frac{1}{4}[/tex] ( multiply both sides by 8 to clear the fractions )

5 - r = - 2 ( subtract 5 from both sides )

- r = - 7 ( multiply both sides by - 1 )

r = 7

Answer:

[tex]\displaystyle 7[/tex]

Step-by-step explanation:

[tex]\displaystyle \frac{-y_1 + y_2}{-x_1 + x_2} = m\\ \\ \frac{-r + 5}{6 + 2} = m \Rightarrow \frac{-r + 5}{8} \hookrightarrow -\frac{2}{8} = -\frac{1}{4} \\ \\ \boxed{7 = r}[/tex]

The regression line equation y = 0.502x +12.250 is a linear regression

The regression line equation is given as:

y = 0.502x +12.250

Substitute 100 for x

y = 0.502 * 100 +12.250

Evaluate the sum

y = 62.45

The regression line equation is given as:

y = 0.502x +12.250

Substitute 500 for x

y = 0.502 * 500 +12.250

Evaluate the sum

y = 263.25

Answer:

$49.55

Step-by-step explanation:

She earns $5.25 every week for 12 weeks, so we multiply her weekly income by 12.

$5.25 * 12 = $63.00

Then she spends $13.45, so we deduct that from her earnings.

$63.00 - $5.25 = $49.55

That shows us that she has $49.55 left.

Answer:

The average rate of change is 20.

Step-by-step explanation:

To find the answer, plug in the 2 and 5 for x.

g(2) = 2(2)^2 - 8(2)

g(2) = 16 - 16

g(2) = 0

g(5) = 2(5)^2 - 8(5)

g(5) = 100 - 40

g(5) = 60

g(5)-g(2)/5-2 = the average rate of change

60/3=20

Step-by-step explanation:

half of 80 is 40

Answer:

40$

Step-by-step explanation:

sale price(S.P.)=discount% of M.P.(marked price)

S.P.=50% of 80$

S.P=50/100*80$

Hence,S.P.(selling price)=0.5*80$=40$

Answer:

  72

Step-by-step explanation:

The given word description can be translated to math symbols this way, when x represents the number:

  3/4x -3/16x = 81

Multiplying by 16 gives ...

  12x -3x = 1296

  9x = 1296 . . . . . . simplify

We want to find the value of half the number, so we can divide this by 18 to get ...

  x/2 = 1296/18 = 72

Half the number is 72.

Answer:

14 cubic units

Step-by-step explanation:

The Formula for Volume is

V = L x W x H

Since there are 2, you need to add the two totals together.

Cubic one:

4 x 1 x 2  =  8 (it also doesn't matter what order you put your numbers in, you will still get the same outcome. Its called the commutative property of multiplication)

Cubic Two:

1 x 3 x 2 = 6

Now just add the totals together:

6 + 8 = 14

Here, we have to find the volume of the solid which is made up of two cuboid. We know that the volume of cuboid is given by:

The volume of the solid will be equal to the sum of volume of given two cuboid

For 1st cuboid :

Therefore, Volume:

➝ V = l × w × h

➝ V = 4 × 2 × 1

➝ V = 8 unit³

For 2nd cuboid:

Therefore, Volume:

➝ V = l × w × h

➝ V = 1 × 2 × 3

➝ V = 6 unit ³

Now, Volume of solid :

‎ㅤ‎ㅤ‎ㅤ➙ sum of V of cuboid

‎ㅤ‎ㅤ‎ㅤ➙ 8 + 6

‎ㅤ‎ㅤ‎ㅤ➙ 14 unit ³

Cramer's rule is used to solve a system of linear equations with n equations in n variables.The basis of this method is matrices and determinants, so we need to understand these two concepts first in order to be able to apply Cramer's Rule in finding solutions to a system of linear equations.

Answer:

[tex]\boxed{a=2,\:b=4}[/tex]

Step-by-step explanation:

[tex]\begin{bmatrix}3a+5b=26\\ a+5b=22\end{bmatrix}[/tex]

Isolate a from 3a + 5b = 26,

[tex]a=\cfrac{26-5b}{3}[/tex]

[tex]\begin{bmatrix}\cfrac{26-5b}{3}+5b=22\end{bmatrix}[/tex]

[tex]\begin{bmatrix}\cfrac{26+10b}{3}=22\end{bmatrix}[/tex]

Now, Isolate b for  

[tex]\cfrac{26+10b}{3}=22\:\:\boxed{b=4}[/tex]

Now, Substitute b=4

[tex]a=\cfrac{26-5\times \:4}{3}[/tex]

[tex]\cfrac{26-5\times \:4}{3}\:\:\boxed{a=2}[/tex]

[tex]\boxed{a=2,\:b=4}[/tex]

[tex]y = - 2x - 7[/tex]

Step-by-step explanation:

One way is to differentiate the function

[tex] \frac{d}{dx} {x}^{2} - \frac{d}{dx} 6[/tex]

Use Power Rule

[tex]2x - 0[/tex]

[tex]2x[/tex]

P

[tex] - 2[/tex]

Plug in -1 so we get

That gives us the slope of the tangent line. we must find the point it passes through.

[tex]( - 1) {}^{2} - 6 = - 5[/tex]

So it have a slope of -2 and passes through (-1,-5)

So we use point slope form

[tex]y + 5 = - 2(x + 1)[/tex]

[tex]y = - 2x - 7[/tex]
