A tourist ignores the warning signs and leaves food in his car while he goes for a hike. A mama bear and her cub open the car door in six seconds. How long would it take each bear to open the car door alone if the cub needs 9 more seconds than the mama bear?
Answer:
0 sec. I help him get the tourist too :)
Step-by-step explanation:
jk, but her cub takes 13 and the mama 4
Using the together rate, it is found that it would take each bear 9 hours to open the car door alone.
What is the together rate?The together rate is the sum of each separate rate.
In this problem, the rates are as follows:
Together rate: 1/6.Mama's rate: 1/x.Cub's rate: 1/(x + 9).Hence:
[tex]\frac{1}{x} + \frac{1}{x + 9} = \frac{1}{6}[/tex]
[tex]\frac{x + 9 + x}{x(x + 9)} = \frac{1}{6}[/tex]
[tex]x^2 + 9x - 12x - 54 = 0[/tex]
[tex]x^2 - 3x - 54 = 0[/tex]
Quadratic equation with coefficients [tex]a = 1, b = -3, c = -54[/tex], hence:
[tex]\Delta = b^2 - 4ac = (-3)^2 - 4(1)(-54) = 225[/tex]
[tex]x_1 = \frac{-b + \sqrt{\Delta}}{2a} = \frac{3 + \sqrt{225}}{2} = 9[/tex]
[tex]x_2 = \frac{-b - \sqrt{\Delta}}{2a} = \frac{3 - \sqrt{225}}{2} = -6[/tex]
It would take each bear 9 hours to open the car door alone.

Which of the following cannot be the lengths of the sides of a triangle?
O 6, 8, 12
O 4,4,6
O 6, 6, 12
O 10, 8, 6
Given:
The sides of a triangles in the options.
To find:
Which of the following cannot be the lengths of the sides of a triangle?
Solution:
In a triangle, the sum of two smaller sides must be greater than the longest side, otherwise it cannot be the lengths of the sides of a triangle.
For option A,
[tex]6+8=14>12[/tex]
For option B,
[tex]4+4=8>12[/tex]
For option C,
[tex]6+6=12[/tex]
Here the sum of two smaller sides is not greater than the longest side. So, the sides 6, 6, 12 cannot be the lengths of the sides of a triangle.
For option D,
[tex]6+8=14>10[/tex]
Therefore, the correct option is C.
6. Solve for x in each of the following equations:
a. m(x + n) =n
b. x( a + b) = b(c - x)
c. mx = n(m + x)
Step-by-step explanation:
m(x + n) = n
mx + mn = n
mx = n - mn
x = (n - mn)/m
x(a + b) = b(c - x)
ax + bx = bc - bx
ax + bx + bx = bc
x(a + b + b) = bc
x(a + 2b) = bc
x = bc/(a + 2b)
mx = n(m + x)
mx = mn+ nx
mx - nx = mn
x(m - n) = mn
x = mn/(m-n)

Find the area of the parallelogram below.
The formula for finding the area of a parallelogram is Base x height
A = Bh
In this case the base (the longest side) is 8 cm and the height (distance between the obtuse angle and the base) is 5 cm
A = 8 * 5
A = 40 cm²
Hope this helps!
~Just a girl in love with Shawn Mendes
Answer: 40cm²
The formula is Base × Height. We can find the area if we multiply the Base and Height.
A = Bh
As for that, the Base is the upper length, which is 8 and the height is the obtuse angle inside the parallelogram, which is 5.
Since we got our lengths, we can solve.
Remember how I said the formula is A = Bh. (Area = Base × Height)
So, we can multiply 8 by 5 to get the area.
8 times 5 will equal 40.
Hence, 40cm² is the answer.

What is the perimeter?
Answer: 12km
Step-by-step explanation:
To find the missing side you need to use the formula a^2 + b^2 = c^2 where C is your hypotenuse.
So your formula would be 4^2 + 3^2 = c^2 ...
16 + 9 = c^2
25 = c^2 so square root both sides. Your missing side is 5km and then add all sides together to find your perimeter.

Qual o raio de uma superfície esférica com 40 cm2 de área, em cm, aproximada às centésimas? Responde à seguinte questão, escrevendo apenas o valor numérico em algarismos
Responder:
1,78 cm
Explicación paso a paso:
El área de superficie total de la superficie esférica se expresa como;
T = 4πr² donde
r es el radio
Dado
TSA = 40 cm²
Sustituir
40 = 4πr²
r² = 40 / 4π
r² = 10 / π
r² = 10 / 3,14
r² = 3,185
r = √3,185
r = 1,78
por lo tanto, el radio de la esfera a la centésima más cercana es 1,78 cm

−3=−5−2v
Step 1: Simplify both sides of the equation.
−3=−5−2v
−3=−5+−2v

−2v−5+5=−3+5
−2v=2

Answer:
[tex]35[/tex]
Step-by-step explanation:
From the information given we can solve for x using the larger triangle
we know that the angle at the top is 45 degrees and the side opposite of it is 35, in other words we need to find the adjacent, or rather, x
Since we have angle, an opposite side, and we need the adjacent. The trig function we need to use is [tex]tan[/tex], the formula is
[tex]tan0[/tex][tex]=\frac{opposite}{adjacent}[/tex]
we need to rearrange this to solve for the adjacent
[tex]adjacent=\frac{opposite}{tan(0)}[/tex]
[tex]x=\frac{15}{tan(45)}[/tex]
[tex]x=35[/tex]

Bill's weight decreases from 64.8 kg to 59.3 kg.
Calculate the percentage decrease in Bill's weight.
Give your answer correct to 3 significant figures.
Answer:
8.48%
Step-by-step explanation:
Bill's weight decreases from 64.8 kg to 59.3 kg.
We need to find the percentage decrease in Bill's weight. It can be calculated as follows :
[tex]\%=\dfrac{64.8 -59.3 }{64.8 }\times 100\\\\=8.48\%[/tex]
So, the required decrease in percentage is 8.48%.
