Answer:
17hrs (a little more)
Step-by-step explanation:
The tank is 1500 gallon capacity, it already contains 200 gallons.
1500-200=1300
Now, you have to figure how many hrs it will take at 75 gallons / hr to reach the additional 1300 gallons.
1300÷75= 17.33
It says full, but not overflowing. So I would say around 17hrs

The area of the figure which consist the two semicircles and one rectangle with 4×8 ft dimensions is 44.6 ft².
What is the area of a rectangle?Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,
A=a\times b
Here, (a)is the length of rectangle and (b) is the width of the rectangle
The given figure is in two parts. It is made with 2 semicircles and 1 rectangle. The length of the rectangle part is 8 ft and width of it is 4 ft long. Thus, the area of this part is,
[tex]A_r=8\times4\\A_r=32\rm\; ft^2[/tex]
There are two semicircles, which make one complete circle. Thus, the area of this two semicircle with radius 2 ft, is,
[tex]A_c=\pi \times2^2\\A_c=12.57\rm\; ft^2[/tex]
Thus, the area of this composite figure is,
[tex]A=A_r+A_c\\A=32+12.57\\A=44.57\rm\; ft^2\\A=44.6\rm\;ft^2[/tex]
Thus, the area of the figure which consist the two semicircles and one rectangle with 4×8 ft dimensions is 44.6 ft².

missing angle is 36
Answer:
36°
Step by step explanation:
✿Determine the measure of angle x
Step 1:
Add together the known angles
97° + 47° = 144°Step 2:
Subtract the sum from 180°
180° - 144° = 36°"so the final answer would be the missing angle"
What’s the answer to this problem?
Answer:
Step-by-step explanation:
LA (Lateral area) = P (perimeter of the base) x h (distance between bases)
LA = 3 x 2
LA = 6
SA (surface area) = LA (Lateral area) + (2 x B (Area of the base))
SA = 6 + (2 x 0.25)
SA = 6.5m²
Answer:
7
Step-by-step explanation:
if you imagine the shape in your head, there would be 3 rectangles and 2 triangles.
so if you want the surface area of the entire shape, you have to add the areas of each of these sides
the area of 1 triangle is (1*1)/2 = 0.5
the area of 1 rectangle is more complicated:
you would have to work out the rectangles height, which is the hypotenuse of the triangle. so you use Pythagoras, and you get 1 (if you don't know how to do this search up Pythagoras theorem)
so now you can get the area of the rectangle: 1*2 = 2
3 rectangles : 2*3 = 6
2 triangles : 0.5 * 2 = 1
6+1 = 7
tbh I'm not sure if you need to do all of this since it does say "estimate" but I'm not sure how you would estimate it.

3
-9
0
-1
Answer:
n = -9
Step-by-step explanation:
4(0.5n − 3) = n − 0.25(12 − 8n)
2n - 12 = n - 3 + 2n
2n - 12 = 3n - 3
2n - 3n = - 3 +12
-1n = 9
n = -9

if the population of a city is 158,000 and is
decreasing by 8% every year, what will the
population be in 5 years?
Answer:
~ 104 135
Step-by-step explanation:
Decreasing by 8% each year means 92% is left each year
Formula
FV = PV ( i)^n FV = population in future PV = pop now
i = 92% in decimal form = .92 n = years = 5
FV = 158000(.92)^5 = 104135
A percentage is a way to describe a part of a whole. The population of the city after 5 years will be 104135.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that the population of a city is 158,000 and is decreasing by 8% every year. Therefore, the population of the city after 5 years will be,
Population after 5 years = 158,000(1-0.08)⁵
= 158,000 × 0.659
= 104134.8807 ≈ 104135
Hence, the population of the city after 5 years will be 104135.

A triangle has angles measuring 35º and 65º. What is the measure of the triangle's third
Answer:
Mean=30
Median=30.5
Mode=None
Range=11
Step-by-step explanation:
The mean is all the numbers added together then divided by how many numberes there are.
24+28+33+35=120
120/4=30
Median is the the middle of the data set when arranged least to greatest. Since its a even number the median will consist of two numbers. 28 and 33
28+33=61
61/2=30.5
Mode is the number most seen in the data set. Theyre all seen once so no mode
Range is the highest value subtracted from the lowest.

. Mrs. Rojas deposited $8000 into an account paying 4% interest annually. After 8 months Mrs. Rojas withdrew the $6000 plus interest. Altogether, how much money did Mrs. Rojas withdraw? What fraction of a year's interest was earned? 760
well, keeping in mind that a year has 12 months, that means that 8 months is 8/12 of a year, when Mrs Rojas pull her money out.
[tex]~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill & \$6000\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ t=years\to \frac{8}{12}\dotfill &\frac{2}{3} \end{cases} \\\\\\ A=6000[1+(0.04)(\frac{2}{3})]\implies A=6000\left( \frac{77}{75} \right)\implies A=6160[/tex]
well, she put in 6000 bucks, got back 160 extra, that's the interest earned in the 8 months.
what if she had left her money for 1 whole year, then
[tex]~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill & \$6000\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ t=years\dotfill &1 \end{cases} \\\\\\ A=6000[1+(0.04)(1)]\implies A=6240[/tex]
so had she left it in for a year, she'd have gotten 6240, namely 240 in interest, well, what fraction of a year's interest was earned? or worded differently, what fraction is 160(8 months) of 240(1 year)?
[tex]\cfrac{\stackrel{\textit{for 8 months}}{160}}{\underset{\textit{for 12 months}}{240}}\implies \cfrac{2}{3}[/tex]

HELP ME PLEASE! I HAD BEEN ON DIS QUESTION FOR TOO LONG!
Which comparison is correct?
7 < |7|
-5 < -4
|5| > 7
|-5| < -4
Answer:
-5 < -4
|X| - this is read as magnitude of X and it means take the positive of that number X.
meaning if the number X is negative you can ignore the negative and write the positive value of the number.
so now:
|7| = 7
|5| = 5
|-5| = 5
7 = |7| not 7 < |7|
-5 < -4 is correct since on the number line numbers to the left are lesser than numbers on the right and -5 is on the left of -4 on the number line
|5| < 7 since |5| is just 5 and 5 is less than 7
|-5| > -4 not -5 < -4 since |-5| is 5 and 5 is greater than -4
hence correct answer is the second one
