Answer:
40
Step-by-step explanation:
20% of 120 which is 24 are lions
half of the animals which is 120 ÷ 2 is 60 for the zebra
therefore, 60+24 is 84
120 - 84 is 36

x = -2 or 3
Step-by-step explanation:
Let z = 2^x. Then the equation becomes ...
[tex]2^{2x+2}+8=33(2^x)\\\\(2^2)(2^x)^2+8=33(2^x)\\\\4z^2+8=33z \qquad\text{substitute $z$ for $2^x$}\\\\4z^2-33z+8=0 \qquad\text{put the quadratic in standard form}\\\\(4z-1)(z-8)=0 \qquad\text{factor}\\\\z=\dfrac{1}{4}\text{ or }z=8\qquad\text{values of z that make the factors 0}\\\\x=\log_2{z}=\{-2,\ 3\}[/tex]
The values of x that satisfy the equation are -2 and 3.
_____
For the graph, we rewrite the equation to the form ...
f(x) = 0
where
f(x) = 2^(2x+2) +8 -33(2^x)
Then the x-intercepts of the function are the solution values for x.

A curve has equation y = 2xy+ 5 and a line has equation 2x + 5y = 1.
The curve and the line intersect at the points A and B. Find the coordinates of the midpoint
of the line AB
Answer:
mid point of AB (0.5 , 0)
Step-by-step explanation:
2x + 5y = 1 2x = 1 - 5y
y = 2xy+ 5 = (1 - 5y)*y + 5 = y - 5y² + 5
y-y = y - 5y² + 5 - y = - 5y² + 5
0 = - 5y² + 5
5y² = 5
y² = 1
y = 1 or y = -1
if y = 1 x = 1/2 (1 - 5) = -2 .... point A (-2 , 1)
if y = -1 x = 1/2 (1 + 5) = 3 ..... point B (3 , -1)
mid point of AB (x' , y') : x' = 1/2 (x₁ + x₂) = 1/2 (-2 + 3) = 1/2
y' = 1/2 (y₁ + y₂) = 1/2 (-1 + 1) = 0
Explain why the solution of 5x – 3 > 14.5 or 5 x minus 3 greater than 14.5 or StartFraction 2 x plus 5 over 3 EndFraction less than 4. < 4 has a solution of all real numbers, with one exception.
Answer:
There is no point where x = 3.5
Step-by-step explanation:
Given the inequality
5x – 3 > 14.5
We are to find the range of all values of x
Add 3 to both sides of the equation;
5x - 3 + 3 > 14.5+ 3
5x > 17.5
x > 17.5/5
x > 3.5
Also for the inequality;
[tex]\frac{2x+5}{3} <4\\[/tex]
Cross multiply;
[tex]2x+5 < 3(4)\\2x + 5 < 12\\[/tex]
Subtract from both sides;
[tex]2x + 5-5 < 12-5\\2x < 7\\x<7/2\\x<3.5[/tex]
The solution to both inequalities are x > 3.5 and x < 3.5. Since there is no point where x = 3.5, hence the solution will have solution on all real numbers except at x = 3.5
Answer:
When solving the first inequality, you get x > 3.5. When solving the second inequality, you get x < 3.5. The solution of an "or” compound in equality is everything in both solution sets, so the solution set is all of the numbers less than 3.5 and greater than 3.5. Since neither of the inequalities includes 3.5, the compound inequality has a solution of all real numbers except 3.5.

What is the number?
10% more than a number is 132.
Step-by-step explanation:
10% more = 110% of the number.
110% of the number = 132
100% of the number = 132 * (10/11) = 120.
The number is 120.
A right triangle, JKL, is given with KJL = 30° and JKL = 90°. KM is drawn such that L, K, and M are collinear. points J and M are joined by JM with JM = JL. Find JML and explain your answer.
A- 30°
B-90°
C-180°
D-60°
Answer:
I tried but soory I can't understand
Answer:
D-60°
Step-by-step explanation:
K,L,M is collinear and JM=JL
M can only be extend to the left of K, otherwise it will overlap with L
JM = JL ΔJML is isosceles triangle ∠JML ≅ ∠JLM
∠JLM = 90 - ∠KJL = 90 - 30 = 60
∠JML = 60°

In the triangle shown below, which altitude length can be found without using the Distance Formula? What is the length?
Answer: a.) the altitude from N to line LM 6 units
Step-by-step explanation: Looking at the graph, you can count the units from the point N to the line, or you can find the difference between 4 and -2: 4- (-2) = 6
The altitude from N to LM is 6 units. Therefore, option A is the correct answer.
From the graph, triangle LMN is given.
What is the altitude length?The length of the altitude, often simply called "the altitude", is the distance between the extended base and the vertex. The process of drawing the altitude from the vertex to the foot is known as dropping the altitude at that vertex.
From the given graph we can see, the altitude from N to LM is 6 units.
Therefore, option A is the correct answer.

Answer:
9 mg
Step-by-step explanation:
We are told in the question above that:
One serving of Raisin Bran cereal contains 50 percent of the 18 mg Daily Value for iron.
Hence, the amount of iron in 1 serving of Raisin Bran cereal =
50% × 18mg

How can I divide 18/15 without any leftovers
Answer:
You can turn the leftovers into a decimal. the answer you would get would be 1.2.
Step-by-step explanation:
Hope this helps and have a nice day!
Answer:
Calculate out how many times the denominator goes into the numerator. To do that, divide 18 by 15 and keep only what is to the left of the decimal point:
18 / 15 = 1.2000 = 1
Multiply the answer from Step 1 by the denominator and deduct that from the original numerator.
18 - (15 x 1) = 3
Keep the original denominator and use the answers from Step 1 and Step 2 to get this:
1 3/15
Minimize the fraction part from Step 3 by dividing the numerator and denominator by 3, which is the greatest common factor, to get the final answer. 18/15 as a Mixed Number is:
1 1/5
Which would also equal to 1.2000.
Hope this kinda helped and made some sense.

One afternoon, 27 people withdraw $100 from an ATM. What was the overall change in the amount of money in the machine?
Answer:
The change is a decrease of $2700.
Step-by-step explanation:
Given
Total Number of people = 27
Amount each person withdrew = $100
The total withdrawn amount by 27 people = 100 × 27
= $2700
Let M be the amount of money in the ATM at the beginning.
As $2700 was drawn from the ATM, therefore, the change the amount of money in the machine will be:
M - 2700It means the change is a decrease of $2700.
Bryce has 10 bals in a bag, each having a distinct color. He randomly picks a ball from the bag 4 times, with replacement. The expected number of distinct colors among the 4 balls Bryce picks can be expressed as a simplified fraction p q . Find p q.
Answer:
p = 1 ; q = 10,000
Step-by-step explanation:
Number of distinct colored balls = 10
Number of balls picked with replacement = 4
Probability = (number of required outcome / number of total possible outcomes)
Distinct picks :
P(1st) = 1 /10
P(2nd) = 1/10
P(3rd) = 1/10
P(4th) = 1/10
Expected Numbe of distinct color:
P(1st) * P(2nd) * P(3rd) * P(4th)
1/10 * 1/10 * 1/10 * 1/10
= 1/10000
p/q = 1/ 10000
p = 1 ; q = 10,000
Find the inverse of f(x)=1/2x Write your answer in terms of g(x).
Answer:
The inverse of f is
[tex]g(x) = 2x[/tex]
Step-by-step explanation:
Given the function
[tex]f\left(x\right)=\frac{1}{2}x[/tex]
A function g is the inverse of function f if for y = f(x), x = g(y)
[tex]y=\frac{1}{2}x[/tex]
Replace x with y
[tex]x=\frac{1}{2}y[/tex]
Solve for y
[tex]y = 2x[/tex]
Therefore, the inverse of f is
[tex]g(x) = 2x[/tex]
