their income is "x", which oddly enough is the 100% of their income, we also know that 16% of it 240 bucks, so
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 240&16 \end{array}\implies \cfrac{x}{240}=\cfrac{100}{16}\implies 16x=24000 \\\\\\ x=\cfrac{24000}{16}\implies x=1500[/tex]

exhibits in total, then what percent of the zoo's exhibits feature lions? Round your
answer to the nearest whole number if necessary.
Answer:
85%
-> If 34 of the 40 exhibits are lions, then 34/40 are lions.
-> 34/40 = 0.85
-> 0.85 * 100 = 85%

A piece of equipment costs $85,000 new but depreciates 15% each succeeding year.
Find its value after 10 years.
Answer: $16,734.32
Step-by-step explanation:
Make an exponential equation where y represents the price of the equipment and x represents the number of years
y = 85,000(1 - 0.15)^x
y = 85,000(0.85)^10
y = 16,734.32
Therefore, the price of the equipment after 10 years will be $16,734.32

What’s the correct answer for this question?
Answer:
9.6 acres
Step-by-step explanation:
First we have to change the yards to feet. 1 yd = 3 ft.
173 yds x 3 = 519 ft
269 yds x 3 = 807 ft
From here, use a calculator if you don't wan't to stress yourself.
807 x 519 = 418833
418833/43560 = 9.61508264463 ≈ 9.6
What is the value of x? □ ft. ( Will Mark Brainliest working on it now ).
Answer:
67.5 ftStep-by-step explanation:
Use the ratio of corresponding sides:
97.5/x = 71.5/(71.5 - 22)97.5/x = 71.5 / 49.5x = 97.5*49.5/71.5x = 67.5solve 4x+4= 2x+10 will give brainliest to whoever answers first

Question 3 (10 points)
(05.04 MO
Circle A has a diameter of 8 inches, a circumference of 25.12 inches, and an area of 50.24 square inches. The diameter of circle B
is 3 inches, the circumference is 9.42 inches, and the area is 7.065 square inches.
Part A: Using the formula for circumference, solve for the value of pi for each circle. (4 points)
Part B: Use the formula for area and solve for the value of pi for each circle. (4 points)
Part C: What observation can you make about the value of pi for circles A and B? (2 points)
Step-by-step explanation:
Part ACircumference formula:
C = 2πr = πdFind π:
25.12 = 8π ⇒ π = 25.12/8 ⇒ π = 3.149.42 = 3π ⇒ π = 9.42/3 ⇒ π = 3.14Part BArea formula:
A = πr² = πd²/4Find π:
50.24 = π*8²/4 ⇒ 50.24 = 16π ⇒ π = 50.24/16 ⇒ π = 3.147.065 = π*3²/4 ⇒ 7.065 = 9π/4 ⇒ π = 4*7.065/9 ⇒ π = 3.14Part CThe value of π is same - 3.14 from each case we haveIf the bases of an isosceles trapezoid have lengths of 15 and 32, what is the

Determine the average rate of change of f (x) = x² - 10x + 5 over the interval [-4, 4].
=
-
Answer:
f ( x ) = ( x - 5 ) ² - 20
Step-by-step explanation:
1- Add the same value to both sides
f ( x ) = x ² - 10x + 5
2- Add 25 to the expression
f ( x ) + ? = x ² - 10x + ? + 5
3- Add 25 to the left-hand side
f ( x ) + ? = x ² - 10x + 25 + 5
4- Factor the expression
f ( x ) + 25 = x ² - 10x + 25 + 5
5- Move the constant to the right
f ( x ) + 25 = ( x - 5 ) ² + 5
6- Calculate
f ( x ) = ( x - 5) ² + 5 - 25

Two cubes each of volume 27^3cm are joined end to end to form a solid. Find the surface area. of resulting solid.
Given :-
Two cubes each of volume 27cm³ are joined to make a cuboid .To Find :-
The surface area of the resulting solid .Solution :-
Given that the volume of cube is 27cm³ . We know that the volume of cube is given by (side)³ .
So , if we assume each side to be a , then ,
[tex]\longrightarrow[/tex] a³ = 27cm³
[tex]\longrightarrow[/tex] a = ³√{27cm³}
[tex]\longrightarrow[/tex] a = ³√3³cm³
[tex]\longrightarrow[/tex] a = 3 cm .
Hence , if we join two cubes we will get a cuboid of length 3cm + 3cm = 6cm . (l)The breadth would be 3cm .( b)The height would be 3cm .(h)See attachment for figure .
And as we know that TSA of cuboid is ,
[tex]\longrightarrow[/tex]TSA = 2( lb + bh + hl )
[tex]\longrightarrow[/tex] TSA = 2 ( 6*3 + 3*3 + 3*6) cm²
[tex]\longrightarrow[/tex]TSA = 2 ( 18 +9 +18 )cm²
[tex]\longrightarrow[/tex] TSA = 2 * 45cm²
[tex]\longrightarrow[/tex] TSA = 90 cm²
Hence the new surface area of the solid is 90cm² .

Use < , > , = , ≤ , ≥ to complete these statements. 1) if x < y , then y___ x, 2) if x > 5 and 5 > y, then x ___ y, 3) if x is four at most, then x ___ 4, 4) if x - y = 0, then x ___ y Can someone please help me I've been stuck on these for 3 days.
Answer:
1) y > x
2) x > 5 > y
3) x ≤ 4 ( or 4 ≥ x )
4) x = y
Step-by-step explanation:
1) 1. y is greater than x
2. so y > x
2) 1. 5 is less than x and more than y
2. we can write this like x > 5 > y
3. you can just squish them together as a shortcut usually: x > 5 and 5 > y --> x > 5 > y
3) 1. x is for at most, we can say this as x is less than or equal to 4
2. this is written as x ≤ 4 or 4 ≥ x
4) 1. x - y = 0 so x and y must be the same value
2. therefore x = y

Two numbers whose product is 40 and sum is -22
Answer:
-2, -20
Step-by-step explanation:
x * y = 40 (1)
x + y = -22 (2)
Multiply by x on (2):
x^2 + xy = -22x
x^2 + 40 = -22x
x^2 + 22x + 40 = 0
(x + 2)(x + 20) = 0
x = -2, -20 (answer)

Answer:
1.15
Step-by-step explanation:
Answer:
1.15
Step-by-step explanation:
So, first it would be helpful to change this from an improper fraction to a mixed number. Because we have an improper fraction now, we need to make this a mixed number by seeing how many times 23 can go into 20. Twenty-three can't go into 20, but if we take away 3 from 23 it can.
So, now we have 20/20 but with a remainder of 3/20. Because 20/20 = 1, it becomes a whole number of 1 and 3/20. Because there is a whole number of 1, we can put this as the whole number for the decimal. The fraction 3/20 is equal to the decimal 0.15, so we can now put the decimal together now that we have all the parts for the answer needed, which is 1.15.
I hope that this helps.

[tex] \orange{ \boxed{ \pink{ {x}^{2} - 9}}}[/tex]
Step-by-step explanation :
We can use the formula that :
(a + b) (a - b) = a(a - b ) + b(a - b)
= a² - ab + ab - b² = a² - b²
_________________________
(x + 3) (x - 3)
We have :
a = x
b = 3
So :
( x + 3 ) ( x - 3 )
x (x - 3 ) + 3 (x - 3 )
x² - 3x + 3x - 9
x² - 9
Answer = x² - 9
A can of soup weights 251 grams. How many cans
Would weigh about a kilograrn?
Answer:
0.251 kg
Step-by-step explanation:
To convert from grams to kilograms, we divide the # of grams by 1000, or move the decimal point to the right by 3.
[tex]25.1[/tex] [tex]2.51[/tex] [tex]0.251[/tex]Therefore, the answer is 0.251 kg.
Answer:
4 cans
Step-by-step explanation:
1kg = 1000g
=> 1000g/251g
= 3.9 cans which is around 4
