A flagpole casts a shadow 16 feet long.
Shanika is standing near the pole. Her
shadow is 4 feet long. Shanika's height is 5
feet. How tall is the flagpole?
Step-by-step explanation:
Since Shanika is standing near the pole, we can safely assume that the triangle formed by Shanika and her shadow is a smaller version of the triangle formed by the pole and its shadow.
By similar triangles:
[tex] \frac{x \: of \: pole}{y \: of \: pole} = \frac{x \: of \: shanika}{y \: of \: shanika} \\ \frac{16}{ height \: of \: pole} = \frac{4}{5} \\ 16(5) = 4 \times height \: of \: pole \\ height \: of \: pole = \frac{80}{4} \\ = 20[/tex]
The height of the pole is 20ft.

Using Proportions to Make a Prediction
Of 25 grocery store shoppers, 14 said that their family’s favorite breakfast is cereal bars. Predict how many of 500 families at grocery store would buy cereal bars.
Of 200 radio-controlled cars that were manufactured by one company, 3 were defective. The company manufactures 1000 cars each day. About how many
defective cars would you predict are produced each day?
HELP......HELP......HELP
Ratio of people who said they like cereal bars to people who said they don't = 14:11
Number of people at a grocery shop = 500
Which means :
[tex] =\tt \frac{14}{25} \times 500 [/tex]
[tex] =\tt \frac{14 \times 500}{25} [/tex]
[tex] = \tt \frac{7000}{25} [/tex]
[tex] \color{plum}= \tt280 \: people[/tex]
Thus, 280 people would buy cereal bars.
▪︎Therefore, out of 500 people, 280 people would buy cereal bars.
○=> Solution (2) :Ratio of cars which worked well to cars which were defective = 297:3
Number of care produced each day = 1000
Number of defective cars produced each day :
[tex] = \tt \frac{3}{200} \times 1000[/tex]
[tex] =\tt \frac{3 \times 1000}{200} [/tex]
[tex] = \tt\frac{3000}{200} [/tex]
[tex]\color{plum} = \tt15 \: defective \: cars[/tex]
Thus, 15 defective cars are produced.
▪︎Therefore, out of 1000 cars produced each day, 15 cars are defective.

Answer:
x = 1
y = 1/5
Step-by-step explanation:
Given the system of linear equations
x + 5 y = 2 .... 1 ×2
6 x + 10 y = 8 .... 2×1
___,_______
2x+10y = 4
6x+10y = 8
Subtract
2x-6x = 4-8
-4x = -4
x = 1
Substitute x =1 into 1
x+5y = 2
1+5y = 2
5y = 2-1
5y = 1
y = 1/5
Hence the solution to the system of equation is (1, 1/5)

Answer:
People's Republic of China
PRC means People's Republic of China.
Step-by-step explanation:
What is PRC? History of rebranding
All products manufactured in China were automatically considered low-quality items for a long period. Even the famous brand or name of the manufacturing plant did not manage to change this stereotype.
China has been the world leader in exporting and manufacturing industrial output since 2014. For the last 50 years, over 370 thousand new factories have started working in the PRC. To reduce the prime cost of goods, a lot of factories have been moved from Europe to China. The remaining factories, for example, those in Germany, France, and Spain, make products for their home markets but produce all goods for export in China.
When you are choosing household appliances pay attention to labels. You will find that most products of highly popular brands are marked “Made in China”. However, it doesn’t mean that – say – a kitchen unit is an imitation of a real food processor from Moulinex, for instance. The fact is that this unit was made at the Moulinex factory in China and it was then sent to your country. The real cost of the food processor produced in China is several times lower than the same one manufactured in and delivered from France. When ordering goods to be produced in China the seller earns more than when producing a similar product in France. Therefore there are so many European brands in our stores, which were produced in China.
European brands produced in China
Spare parts for smartphones from China
The case of spare parts for smartphones, tablets and laptops is even more complicated. It is commonly known that almost all spare parts are produced in China. Nevertheless, to buy a spare part for Samsung or Apple here is almost impossible. Their factories are protected by all means available. Spare parts from these factories are sent to Europe, where they are distributed among branches. Therefore you can buy the Original item only in the company's official representative office.
However, the Chinese people would not be Chinese if they were not able to make money on such expensive products. They manufacture the same spare parts but not at official factories. After learning the manufacturing technology of displays, touchscreens and flat cables, the local craftsmen create a device that can make spares identical to the original. Such spare parts are considered high quality products and belong to the High Copy level.
Original PRC means that the spare part consists of original components. For example, the seller has original LCDs and doesn’t have original touchscreens. In such cases, the High Copy touchscreen is installed on the original display. Such LCD module will be classified as Original PRC because one of its components is original. There can also be another scenario. Imagine that the seller has both the original LCD and touchscreen but the customer needs a module, not a separate spare part. In this situation, a handyman sticks together the LCD and the touchscreen and here is the module. Such a spare part is called Original PRC because it’s made of original components even though it is not manufactured at the official factory. The main difference between Original PRC and Original is the place where they were made. The quality of Original PRC spares doesn’t differ from Original. Still the difference in price is significant.

Katrina drinks 0.5 gallons of water per day. Which expression shows how to find the number of cups of water she
drinks in a week?
There are 16 cups in a gallon.
Answer:
Katie drinks 56 cups (3.5 gallons) of water in one week.
Step-by-step explanation:
16 - 0.5 (1/2) = 0.5 (1/2)
16 - 1/2 = 8
8 x 7 days (1 week)
= 56 cups
Katie drinks 56 cups (3.5 gallons) of water in one week.

dos numeros sumados dan como resultado 5 y el doble de uno mas el doble del otro da como resultado 15 ¿cuales son esos numeros?
Answer:
Sean dos números A y B.
Sabemos que la suma de estos dos números es igual a 5, entonces:
A + B = 5
Y sabemos que el doble de uno mas el doble del otro da como resultado 15.
entonces:
2*(A + 2*B) = 15
esta es la única forma de interpretar esta ecuación, si en lugar de esta expresión tuviéramos 2*A + 2*B = 15 (pues tambien se puede interpretar como esto), entonces:
tenemos dos ecuaciones:
A + B = 5
2*A + 2*B = 15
Ahora, si sacamos el 2 como factor común en la segunda ecuación tenemos:
2*(A + B) = 15
si dividimos ambas partes por 2:
(A + B) = 15/2 = 7.5
(A + B) = 7.5
Esto se contradice con la primer ecuación:
(A + B) = 5.
Entonces podemos concluir que dichos números no existen.
Dejando esto de lado, nuestras ecuaciones van a ser:
A + B = 5
2*(A + 2*B) = 15
Para resolver esto, el primer paso es aislar una de las variables en una de las ecuaciones, yo voy a aislar A en la primera:
A = 5 - B
Ahora podemos reemplazar esto en la otra ecuación:
2*(5 - B + 2*B) = 15
2*(5 + B) = 15
10 + 2*B = 15
2*B = 15 - 10 = 5
B = 5/2 = 2.5
Y con la primer ecuación:
A + B = 5
reemplazamos el valor de B:
A + 2.5 = 5
A = 5 - 2.5 = 2.5
Ambos números son 2.5.

Write a linear equation that gives the rule for this table.
Hint: Linear Functions are of the form y=mx+b
Answer:
y=x
Step-by-step explanation:
If we look at this then this is a y=mx+b graph
first lets find the rise/run
so rise = how much it goes up and run = how much it goes right or left
the rise/run of this graph is 1 because each time it goes one up it goes one right.
B= y intercept and the y intercept is 0
So it is y=1x+0 or y=x
answer = y=x
At midnight in Minnesota, the temperature was -59. Over the next three hours, the
temperature dropped 7. What was the temperature at 3:00 a.m.?
A-12
B-5°
C -2°
D 2
PLEASE HELP!!!
9514 1404 393
Answer:
A. -12°
Step-by-step explanation:
The final value is found by adding the change to the initial value.
final temp = initial temp + change in temp
final temp = -5° + (-7°) = (-5 -7)°
3 am temp = -12°
Answer:
A
Step-by-step explanation:
1. Write the equation: -5-7. We get that equation because we start at -5 and then it drops 7 degrees. "dropped" is the keyword that tells us to subtract.
2. Solve the equation: -12 degrees. You can solve it very easily by plugging it into a calculator or mentally.
P.S: You typed the question wrong, you said 56 degrees instead of 5. That really had me stumbled lol.
