                           = 16.67%

Answer:

Height of the boy is 1.4 m and casts a shadow of 1.2 m

At the same time, a building casts a shadow of 5.4 m and suppose height of the building is x m

Then ratio of their heights and shadows are in proportion

⟹1.4x=1.25.4

⟹x=1.21.4×5.4

⟹x=6.3

Hence, height of the building is 6.3 m.

First thing you do is find the difference between the years recorded. So from 2008 to 2010 is two years. Second you find the difference between the populations which is 51,336 then divide it by two and you get the average growth in the population of 25,668

Answer:

2x - y - 5z

Step-by-step explanation:

Given

-[z - 3y - (3x - z - 2y) + 3z + 2y] - x =

Distribute the subtraction into the ()

-[z - 3y -3x + z + 2y + 3z + 2y] - x =

Move the terms around, keeping the sign with the term

-[z + z + 3z - 3y + 2y + 2y - 3x] - x =

Combine like terms

-[2z + 3z - 3y + 2y + 2y - 3x] - x =

-[5z - 3y + 2y + 2y - 3x] - x =

-[5z - y + 2y - 3x] - x =

-[5z + y - 3x] - x =

Distribute the subtraction into the []

-5z - y + 3x - x =

Combine like terms

- 5z - y + 2x

Reorder:

2x - y - 5z

Step-by-step explanation:

The solution set of the given quadratic equation using factorization will be {-3,11}

Given equation is

[tex]x^{2} -8x-33 = 0[/tex]

The polynomial equation whose highest degree is two is called a quadratic equation. The equation denoted by ax² + bx + c = 0, where a is non-zero.

Let us calculate the roots by factorization

[tex]x^{2} -11x+3x-33=0[/tex]

[tex]x(x-11)+3(x-11)=0[/tex]

[tex](x-11) (x+3)=0[/tex]

[tex]x-11=0\\x=11\\x+3=0\\x=-3[/tex]

Hence, the solution set of the given quadratic equation will be {-3,11}

Step-by-step explanation:

4.8(x)+1.2(y)=2.4

9.6 + 1.2y = 2.4

subtract 9.6 from both sides

1.2y = - 7.2

divide by 1.2 on both sides

y = -6

Answer:

[tex] \displaystyle\boxed{\rm \: Distance= \underline{\underline{\sqrt{13}}}} [/tex]

OR in Decimal,

[tex] \boxed{\rm \: Distance=\underline{\underline{3.605}}}[/tex]

Step-by-step explanation:

Given:

Two points, that is (5,3) & (8,5)

To Find:

The Distance of the two given points

Solution:

To Find the distance between two points, we will use the distance formula, i.e. :

[tex] \boxed{ \rm \: Distance = \sqrt{(x_2 - x_1) {}^{2} + (y_2 - y_1) {}^{2} } }[/tex]

According to the Question,

[tex] \rightarrow \: \rm \: x_2 = 8[/tex]

[tex]\rightarrow \: \rm \: x_1 = 5[/tex]

[tex]\rightarrow \: \rm \: y_2 = 5[/tex]

[tex]\rightarrow \: \rm \: y_1 = 3[/tex]

Now Substitute the values on the formula of Distance and then Simplify:

[tex] \rm \: Distance= \sqrt{(8 - 5 )^{2} + (5 - 3) {}^{2} } [/tex]

[Follow PEMDAS rule while simplifying]

[tex] \rm \: Distance= \sqrt{3 {}^{2} + 2 {}^{2} } [/tex]

[tex] \rm \: Distance= \sqrt{(3 \times 3) + (2 \times 2)} [/tex]

[tex] \rm \: Distance= \sqrt{9 + 4} [/tex]

[tex] \rm \: Distance= \sqrt{13} [/tex]

[tex] \rm \: Distance= {3.605} [/tex]

Hence, the distance between the two given points would be [tex]\sqrt{13}[/tex] or [tex] 3.605 [/tex].

Answer:

(B) 16.7 kg

Step-by-step explanation:

First, start by converting everything to kilograms (using unit converters):

[tex]250g(\frac{10^{-3}kg}{1g})=250*10^{-3}kg=0.25kg[/tex]

Then, add all the weights together:

[tex]100kg+0.25kg+150kg+0.25g=250kg+0.5kg=250.5kg[/tex]

Now, divide this number by 15 (since they are packed in 15 bags):

[tex]\frac{250.5kg}{15}=16.7 kg[/tex]

(B) 16.7 kg

Answer:

30 hours of work

Step-by-step explanation:

Ok if Mr. White  works 10 hours he gets 250$
250+250=500$
10 + ㅤ10 = 20 hours
500+250=750
20ㅤ+ 10 = 30

so this means he will have to work 30 to get 750$

Answer:

30 hours

Step-by-step explanation:

If 10 hours = $250

Than you can divide 750/250 and you’ll get 3. Multiply 3 by 10 ( 3 • 10 ) and you’ll get 30 hours.

Step-by-step explanation:

Answer:

89.8 inches

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]\sqrt{82}=9.06[/tex]

10² ÷ 5 *√82 - π*2 = 100÷ 5 *9.06 - 3.14*2

                              = 20 *9.06 - 3.14*2

                              = 181.2 - 6.28

                              = 174.92

or

10² ÷5 *√82 - π*2 = 100÷5 *√82 - 2π

                             = 20√82-2π

Answer:

[tex]10^2 \div 5 \times \sqrt{82} - \pi \times 2[/tex]

Using order of operations, we need to carry out the exponents first:

[tex]10^2=10 \times 10=100[/tex]

[tex]\implies 100 \div 5 \times \sqrt{82} - \pi \times 2[/tex]

Then we need to carry out multiplication and division (it doesn't matter in which order):

[tex]\implies 100 \div 5 \times \sqrt{82} - \pi \times 2[/tex]

[tex]\implies 20\times \sqrt{82} - 2\pi[/tex]

[tex]\implies 20\sqrt{82} - 2\pi[/tex]

Unless you have been given an approximation for pi, it cannot be simplified any further.

[tex]20\sqrt{82} - 2\pi=1.748245175...[/tex]

Check the picture below.

now, when it comes to limits, we're not concerned if the value of the function is the same as the limit at that location, we're only concerned on to where is the function approaching, now it may not get there, but that is where it's approaching or seem to be approaching.

in this case, the piece-wise function has a hole when x = 3, meaning f(x) ≠ 3 when x = 3, however if we look at the progress from say 6, 5.9, 5.5, 5.1, 4.9, 4.8, 4.1, 3.7, 3.000001, it seems to be approaching 3, thus that is its limit.
