Answer:
Step-by-step explanation:
person height/shadow length = lamp height / shadow length lamp
Person height = 164 cm
shadow length = 83
lamp height = x
lamp shadow length = 366 + 83 = 449
164/83 = x/449 Cross Multiiply
83x = 164 * 449 Combine Right
83x = 73636 Divide by 83
x = 73636/83
x = 887.18

divide 182kg in the ratio 2:3:8
The equivalent values for the ratio 2 to 3 to 8 is 28kg, 42kg and 112kg
Ratio and proportionsGiven the following parameters
Total weight = 182kg
If the weight is divide in the ratio 2:3:8, th3n the total ratio will be;
total ratio = 2 + 3 + 8
Total ratio = 13
For the ratio of 2;
Portion =2/13 * 182
Portion = 28kg
For the ratio of 3;
Portion =3/13 * 182
Portion = 42kg
For the ratio of 8;
Portion =8/13 * 182
Portion = 112kg
Hence the equivalent values for the ratio 2 to 3 to 8 is 28kg, 42kg and 112kg

HURRY 20 POINTS! Which ordered pair is a solution of the equation shown?
y=3/4x+1/2
Answer:
A
Step-by-step explanation:
3/4*(-4/3) + 1/2 = -1 + 1/2 = -1/2
First, B is not the answer, because if x = 0, the whole equation would've been 0.
A) -4/3 ; -1/2
Replace x and y with the 2 fractions, we have : 3/4 x (-4/3) + 1/2 = -1/2
-1 + 1/2 = -1/2 (true)
So, A is correct
But to make sure, we'll go over C and D also.
C) 4/3 ; 1/2
Replace x and y : 3/4 x 4/3 + 1/2 = 1/2
1 + 1/2 = 1/2 (not true)
So this is not the answer
D) 4 ; 3/2
Replace x and y : 3/4 x 4 + 1/2 = 3/2
3 + 1/2 = 3/2 (not true)
So, A is correct.

Suppose you are starting a new job and you are told there are two options you can choose from regarding how you are paid. Option 1: you earn $1 on the first day of your new job and double your previous amount each week for 6 months (so after the first week you get $2, after the second week you get $4, and so on....). Option 2: you can accept one total sum for $65,536. Which option would you choose? (P.S. Either way! want that job!). Hint: Use 2" = 65,536 where o represents the number of weeks you have to work to make the offered amount of money.
ILL MARK YOUR ANSWER AS BRAINLIEST IF U ANSWER
Answer: Picking the first option and constantly adding on and on you will eventually make way more than what the second option proposes, therefore picking the first option is the obvious choice.
Step-by-step explanation:
Well let’s see it starts off slow for instance 1, 2, 4, 8, 16 and so on adding that on for a month will eventually leave you with more.

7. B. 417.6
8. 138.98
Explanation:
6) (7x-5) - (3x-2)
7x-5 - 3x+2
distribute the -1 from the middle into (3x-2) which only changes the signs
7x-5 - 3x+2
collect like terms (7x and -3x) as well as (-5 and 2)
Answer---> 4x-3
7) 0.5x+78.2=287
-78.2 -78.2
move the constant to the right side and change it's sign
0.5x=287-78.2
--> 0.5x= 208.8
Subtract the numbers on the right hand side
0.5x= 208.8
------ --------
0.5x 0.5x
divide both side of the equation by 0.5
answer ---> x= 417.6
8) Given: Graham's monthly bank statement with deposits and withdrawals:
-25.20,−25.20,52.75,-22.04,−22.04,-8.50,$94.11
If Graham's balance in the account was $47.86 at the beginning of the month .
Then the account balance at the end of the month =
=47.86+(-25.20+ 52.75- 22.04- 8.50+ 94.11)
=47.86+(52.75 + 94.11 − 25.20− 22.04− 8.50)
=47.86+(146.86− 55.74)
47.86+(91.12)=47.86+91.12= 138.98
Thus, the account balance at the end of the month= $138.98

V = [tex]\frac{7}{8}[/tex] units³
Step-by-step explanation:
the volume (V) of the prism is calculated as
V = Ah ( A is the area of the base and h the height ) , then
V = [tex]\frac{1}{2}[/tex] × 1 [tex]\frac{3}{4}[/tex] ( change mixed number to improper fraction )

The circumference of a circle is 4pi. Find its radius, in feet.
Answer: 2
Step-by-step explanation:
The circumference of a circle is 2*radius*pi.
We can set up an equation as we know the circumference as 4pi.
4pi = 2*radius*pi
Divide both sides by pi:
4 = 2*radius
Divide both sides by 2:
radius = 2
Answer:
2 ft
Step-by-step explanation:
The equation for circumference is:
[tex]C=2\pi r[/tex]
We can plug in the given value for circumference to solve for the radius.
[tex]4\pi=2\pi r[/tex]
Divide both sides by 2π
[tex]\frac{4\pi}{2\pi}=r\\r=2\ ft[/tex]

[tex]Answer:[/tex]
No. They are not equivalent because sure, we can multiply them by 5,000 to get these 2 numbers, but 7 is not divisible by 5,000
Therefore, they are not equivalent ratios.
A circular sprinkler system is installed and waters an area of 78.5 square yards. What is the radius of the circle? Draw a picture and show all your work.
Answer:
The radius of the circle is about 5
Step-by-step explanation:
The formula for the radius of the circle with a area is:
- R= the square root of the area divide by pi ( π)
or - R= the square root of A/ π
Plug in 78.5 into the formula
then you get the radius which is 5.

3x—2
X+38
……………………………….
Answer:
x = 20; angles = 58°
Step-by-step explanation:
Since the given triangle is an isosceles triangle & the 2 opposite angles are equal, then even the opposite angles of the equal opposite sides will be equal.
So,
3x - 2 = x + 38
3x - x = 38 + 2
2x = 40
x = 40/2
x = 20
Angles:
■ 3x - 2
= 3(20) - 2
= 60 - 2
= 58°
■ x + 338
= 20 + 38
= 58°
=》Both the angles are equal & each measure 58°

Answer:
B. 7√2
Step-by-step explanation:
One of the trigonometry formulas to find a missing side is:
sin θ = opp/hyp
Substituting those values in with the ones we have, we will get:
sin (45deg) = x/14
√2/2 = x/14
14(√2/2) = x
x = 7√2

Question: find the measure of the indicated angle in each triangle
answers:
A: 129
B: 360
C: 80
D:180
Answer:
Step-by-step explanation:
3 angles in a triangle always add up to be 180.
So, angle prq = 180 - 49 - 80 = 51
Angle qrx is supplementary to prq => angle qrx = 180 - 51 = 129
