Question:A water tank is shaped like the cone shown here. How much water can the tank hold? Use 3.14 for . If water is drained from the tank to fill smaller tanks that each hold 200 m³ of water, how many smaller tanks can it fill
Answer:
Amount of water = 871.87 in³
Number of tanks = 4 tanks
Step-by-step explanation:
Applying,
V = 1/3πr²h........... Equation 1.
Where V = volume of the tank, h = height, r = radius.
From the diagram attached,
Given: h = 17 m, r = 7 m.
Substitute these values into equation 1
V = 1/3(17)(7²)(3.14)
V = 871.87 m³.
Hence the amount of water the tank can hold is 871.87 m³
If the water is drained to a tank of 200 m³,
The number of tanks it can fill is = 871.87/200 = 4 tanks.

A sample proportion of 0.36 is found. To determine the margin of error for this statistic, a simulation of 100 trials is run, each with a sample size of 50 and a point estimate of 0.36.
The minimum sample proportion from the simulation is 0.28, and the maximum sample proportion from the simulation is 0.40.
The margin of error of the population proportion is found using half the range.
What is the interval estimate of the true population proportion?
A.)(0.24, 0.48)
B.)(0.30, 0.42)

Answer:
Finding the area of a large rectangle is A = l × b
Step-by-step explanation:
A= Area, while I=length and B= the base, the way to find the area of the big one is by finding the area of the small ones first then adding them together,
Example: (a=lxb) + (a=lxb) = Area of big rectangle

Avery is currently making $14 per hour at her job. Her boss gives her a 15% raise for showing good work ethic.
If she works 40 hours per week, how much more will Avery be making than before her 15% raise?
A.$15.00
B.$280.00
C.$84.00
D.$116.00
Answer:
C) $84
Step-by-step explanation:
40 x 14 = 560
she made $560 prior to raise
14 x 1.15 = 16.10
her new hourly rate is $16.10
40 x 16.1 = 644
she now earns $644 per week
644 - 560 = 84

Factor
X^2 + 6x + 9
Please show all work and use a factor tree
Answer:
Step-by-step explanation:
X^2 and 9 are two squares, while 6 can be obtain my multiplying x and 3 by 2.
so this is a square of a binomial
(x+3)^2
or
(x+3)(x+3)
Answer:
(x+3)², if looking for x, X = -3
Step-by-step explanation:
X²+6x+9 is a perfect square as you immediately can see that 3+3 = 6 and 3*3 = 9.
I used the generic rectangle to solve it, 9 into top right corner and then x² onto the bottom left, multiplying eachother to get 9x² which is formed by 3x and 3x multiplied so you would have (x+3) (x+3).

Boston , Massachusetts, and buffalo, New York, are hit by snowstorms that last 3 days . Boston accumulates snow at a rate of 1.5 feet every 36 hours. Buffalo accumulates snow at a rate of 0.01 inches every minute.
What is the ft and in
Question is ;
Complete question is;
Boston , Massachusetts, and buffalo, New York, are hit by snowstorms that last 3 days . Boston accumulates snow at a rate of 1.5 feet every 36 hours. Buffalo accumulates snow at a rate of 0.01 inches every minute.
Which city accumulates more snow in 3 days? How much more snow?
Answer:
- Boston accumulates more snow in 3 days.
- It accumulates 0.6 ft of snow more than Boston
Step-by-step explanation:
Boston accumulates 1.5 feet of snow every 36 hours.
Number of hours in 3 days = 24 × 3 = 72 hours.
Thus, In 72 hours, Boston would have accumulated; (1.5 × 72)/36 = 3 feet of snow.
Now, Buffalo accumulates 0.01 inches of snow every minute.
In 3 days, number of minutes we have = 60 × 24 × 3 = 4320 minutes
Thus, total snow accumulated in 3 days = 0.01 × 4320/1 = 43.2 inches
Now, let's convert this to ft;
12 inches = 1ft
Thus; 43.2 inches = 43.2 × 1/12 = 3.6ft
Thus, Buffalo accumulates more snow in 3 days.
It accumulates 0.6 ft of snow more than Boston

Draw a scaled plan
From the question, the garden has the following dimensions.
5.5m, 5.5m, 4m and 2.5m
Using a scale of 1m : 50 cm units, the above measurements will be represented as:
[tex]5.5m \to \frac{5.5m}{50cm} \to \frac{5.5m}{0.5m} \to 11cm[/tex]

Find the missing number based on the description below. 11 less than four times a number is the same as 46 less than the product of -1 and the number
Given:
11 less than four times a number is the same as 46 less than the product of -1 and the number.
To find:
The missing number.
Solution:
Let x be the missing number.
Four times a number = 4x
11 less than four times a number = 4x-11
Product of -1 and the number = (-1)x
= -x
46 less than the product of -1 and the number = -x-46
The given statement is "11 less than four times a number is the same as 46 less than the product of -1 and the number". So,
[tex]4x-11=-x-46[/tex]
[tex]4x+x=11-46[/tex]
[tex]5x=-35[/tex]
Divide both sides by 5.
[tex]x=\dfrac{-35}{5}[/tex]
[tex]x=-7[/tex]
Therefore, the missing number is -7.

Round 958.989730738 to the nearest hundred.
Answer:
958.99
Step-by-step explanation:
Assuming you meant "hundredth", for the nearest hundredth term you would need to round up to the 2nd number behind the decimal. The thousandth digit of the number is 9, since 9 is greater than 4, you would need to round up by 1 to get 958.99.

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = (8, 7) and (x₂, y₂ ) = (1, - 2)
d = [tex]\sqrt{(1-8)^2+(-2-7)^2}[/tex]

Andrea used 4 1/3 yards of material to make a dress she has 1 1/4 yards left over how much material did Andrea start with
Answer:
[tex]1\frac{7}{12}\quad[/tex] yards [tex]\left(\mathrm{Decimal:\quad }\:1.58333\dots \right)[/tex]
Step-by-step explanation:
To find how much Andrea started with, subtraction is needed. To subtract, we need to set up fractions;
[tex]4\frac{1}{3}-\frac{11}{4}[/tex]
Convert the mixed number to an improper fraction: [tex]a\frac{b}{c} = \frac{a \cdot c+b }{c}[/tex][tex]4\frac{1}{3}=\frac{4\cdot 3+1}{3}[/tex]
[tex]=\frac{13}{3}[/tex]
[tex]=\frac{13}{3}-\frac{11}{4}[/tex]
Least common multiplier: 3,4 = 12
Adjust fractions based on the LCM
[tex]=\frac{52}{12}-\frac{33}{12}[/tex]
Apply the fraction rule: [tex]\quad \frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}[/tex]
[tex]\frac{52}{12}-\frac{33}{12}=\frac{52-33}{12}[/tex]
[tex]=\frac{52-33}{12}[/tex]
Add the numbers: [tex]52-33=19[/tex]
[tex]=\frac{19}{12}[/tex]
Convert the improper fraction to mixed numbers: [tex]Quotient \frac{Remainder}{Divisor}[/tex][tex]\frac{19}{12}=1\frac{7}{12}[/tex]
[tex]=1\frac{7}{12}[/tex]
Therefore, Andrea started with [tex]1\frac{7}{12}[/tex] yard material.
