2/4th of the area was occupied by Himalayan panda, 1/6th by Giant Panda and 2/12th by Albino panda and remaining area by brown Panda. What is the brown panda's area
Answer:
[tex](\frac{1}{6}) ^{th}[/tex] of area
Step-by-step explanation:
Area occupied by Himalayan panda = [tex]\frac{2}{4}^{th}[/tex] of area
Area occupied by Giant Panda = [tex]\frac{1}{6} ^{th}[/tex] of area
Area occupied by Albino panda = [tex]=\frac{2}{12} ^{th}[/tex]of area
Area occupied by brown Panda = [tex](1-\frac{2}{4}-\frac{1}{6}-\frac{2}{12}) ^{th}[/tex] of area
= [tex](\frac{12-6-2-2}{12} )^{th}[/tex] of area
= [tex](\frac{2}{12}) ^{th}[/tex]of area
= [tex](\frac{1}{6}) ^{th}[/tex] of area

BRAINLIST!!! "Twenty-eight is more than four times another number" can be shown by the inequality 28 > 4n. Select the values of n which could possibly make this a true statement.
Options
4
6.65
7
8 1/3
n>7
Answer:
6.65
Step-by-step explanation:
Answer:
n < 7 (n must be strictly less than 7)
so 4 and 6.65 can make this statement true
Step-by-step explanation:
28 > 4n
solve as if it is a normal equation,
divide both sides by 4
n < 7
n must be less than 7
so 4 and 6.65 are values that make the statement true

Tommy and Mark earned a total of $88.00 raking leaves for Mrs. Bopp. Tommy raked for 5 hours and Mark raked for 3 hours. If the boys were paid the same rate, how much did Tommy earn?
Answer:
Tommy earned $55
Step-by-step explanation:
Proportions
Tommy and Mark made $88 raking leaves for Mrs. Bopp. They were paid the same rate and Tommy raked for 5 hours while Mark raked for 3 hours.
The total time both raked is 5+3=8 hours. The rate Mrs. Bopp paid them was $88/8 = $11 per hour.
Tommy raked 5 hours, so he earned 5*$11 = $55
Tommy earned $55

Jessica is a custodian at Oracle Arena. She waxes 20 m2 of the floor in 3/5 of an hour. Jessica waxes the floor at a constant rate. At this rate, how many square meters can she wax per hour?
Answer:
33.3m^2
Step-by-step explanation:
If Jessica waxes 20 m^2 of the floor in 3/5 of an hour, then;
20m^2 = 3/5 hr
To get the area that she waxes in an hour
x = 1 hr
Divide both expression
20/x = 3/5
3x = 20 * 5
3x = 100
x =100/3
x = 33.3m^2
Hence she can wax 33.3m^2 in an hour
-2/3 x - 1 =19 yeah its -2over3 with x to the right then -1 = 19
Answer:
x = 30
Step-by-step explanation:
Given the expression
-2/3 x - 1 =19
We are to find the value of x
Add 1 to both sides
2/3 x -1 +1 = 19+1
2/3 x =20
Multiply
2/3x × 3 = 20×3
2x = 60
x = 60/2
x = 30.
Hence the value of x is 30

The sixth-graders at Jen's school got to choose between a field trip to a museum and a field trip to a factory. 57 sixth-graders picked the museum and 38 sixth-graders picked the factory. What percentage of the sixth-graders picked the museum?
Answer:
60% choose the Museum.
Step-by-step explanation:
Add the students who choose the museum and the students who choose the factory to get 95. You would then need to divide the amount of students who choose the museum by the total amount of students. Your answer would be 0.6, or 60%
60% of the students sixth-graders at Jen's school picked the museum.
What is the percentage?A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.
Given, 57 sixth graders picked the museum and 38 sixth graders picked the factory.
So, the total no. of students is (57 + 38) = 95.
∴ The percentage of the sixth-graders who picked the museum is,
= (57/95)×100%.
= 60%.

At the circus, a clown is shot from a cannon. This situation can be modeled by the function: h = – 16t2 + 45t + 15, where 'h' is height in feet and 't' is time in seconds. What is the maximum height of the clown?
A. 45 Feet
B. 109. 4 Feet
C. 72.3 Feet
D. 87.3 Feet
Answer:
The maximum height is 46.64 feet.
Step-by-step explanation:
If we take the derivative of h whit respect to t and equal this to zero we would find the value of t which corresponds to the maximum h.
So, we have the function h(t):
[tex]h(t)=-16t^{2} + 45t + 15[/tex]
Taking the derivative, we have:
[tex]\frac{dh(t)}{dt}=-32t + 45=0[/tex]
Now, we solve it for t:
[tex]t=\frac{45}{32}=1.4\: s[/tex]
Finally, we put this value of t into the original equation.
[tex]h(t)=-16(1.4)^{2} + 45(1.4) + 15[/tex]
[tex]h_{max}=46.64\: ft[/tex]
Therefore, the maximum height is 46.64 feet. All the given options are wrong, the one that comes closest is option A.

The bearing of Measham from Tamworth is 052°
Calculate the bearing of Tamworth from Measham.
Answer:
232°
Step-by-step explanation:
1. 180-52=128
2. 360-128=232
first you subtract 52 from 180 bc you have to get the angle not included for calculating the whole bearing bc the starting point is the north line. so everything before the north line is not valid bc when you're calculating an angle like this you go from lef to to right, clockwise. in every calculation of bearings you go clockwise. next you just subtract the product you got from 360 and that's it.

How many terms are there in each expression? a. 9x − 4y + 7z − 8w + t b. Ab + 3a − 4b c. 25a + 9bc − 8def
Answer:
a. 5
b. 3
c. 3
Step-by-step explanation:
Terms are variables, the number connected to the term is called the coefficient, the variable does not need a coefficient to be considered a term. There are 5 terms in a (9x,4y,7x,8w,t) 3 terms in b (Ab,3a,4b) and 3 terms in c (25a,9bc,8def).
Notice how there are multiple variables in sets b and c. Do not get confused into thinking these are multiple terms, they are one. A term is a single expression with one or more variables that are multiplied but never added or subtracted. Ex: abc is one term but 3 variables.
