Answer:
-5.230,0000
Step-by-step explanation:
Your number in decimal form is -52,300,000 . The negative sign remains unchanged. To get to "standard" scientific notation, we move the decimal point so there is only one non-zero digit in front of the decimal point. So, -52,300,000 becomes -5.230,0000

Answer:
b = 2Step-by-step explanation:
We know that:
a/b + c/d = (ad + bc)/bdWe observe the denominator of the first expression is same as the product of the denominators of the second expression.
Compare the numerators and solve for b:
5(x - 1) - 4(x - b) = x + 35x - 5 - 4x + 4b = x + 3x - 5 + 4b = x + 34b - 5 = 34b = 8b = 2the graph shown here is the graph of which of the following rational functions?
a. f(x)= 1/x-1
b. f(x)= 1/x
c. f(x)= 1/x+1
Answer:
A
Explanation:
when A's function has x=1, the denominator would be 0, producing an asymptote. Looking at the function, there is an asymptote at x=1, which means it matches A.

Britton rotated trapezoid ABCD 180° on the coordinate plane. If angle B is 20° and angle D is 90°, what is the degree measurement of angle B′?
Group of answer choices
20°
70°
90°
180°
Answer:
20°
Step-by-step explanation:
Rotation is one of 3 basic rigid transformation, it will not change the original shape and size. Therefore angle B' should be still 20°
The degree measurement of angle B′ will be same as angle B that is 20°. Then the correct option is A.
What is a transformation of a shape?A point, line, or geometric figure can be transformed in one of four ways, each of which affects the structure and/or location of the object.
From before the refers to the object's initial condition, and Picture, after transformation, refers to the object's ultimate structure and location.
Rotation does not change the shape and size of the geometry. But changes the orientation of the geometry.
If the geometry is rotated, then there is no change in anlges.
Britton rotated trapezoid ABCD 180° on the coordinate plane. If angle B is 20° and angle D is 90°.
The degree measurement of angle B′ will be same as angle B that is 20°.

Henry and his little brother made up a game using coins. They flip the coins towards a cup and receive points for every one that makes it in. Henry starts with 15 points, and his little brother starts with 20 points. Henry gets 3 points for every successful shot, and his brother, since he is younger, gets 2 points for each successful shot. Eventually, the brothers will have a tied score in the game. How many additional shots will each brother have made?
Write a system of equations, graph them, and type the solution.
Answer:
After 5 additional shots, the brothers will have a tied score.
Step-by-step explanation:
find equations
henry:
y-int is 15 because that is the starting number. the slope is 3 because that is how much his points are increasing for every successful shot. we can use this information to form this equation:
y = 3x + 15
brother:
y-int is 20 because that is the starting number. slope is 3 because that is how many points he gets for each successful shot. using this information, we can form the following equation:
y = 2x + 20
--
solve
y = 3x + 15
y = 2x + 20
3x + 15 = 2x + 20
x + 15 = 20
x = 5

Profit is revenue minus cost. Find the profit if the cost of producing x units of a commodity is
130+25x and the revenue for selling them is x(88-X).
Answer:
[tex]-x^2+63x-130[/tex]
Step-by-step explanation:
When you put that into an equation:
[tex]x(88-x)-(130+25x)[/tex]
Next, solve.
[tex]\mathrm{Apply\:the\:distributive\:law}:\quad \:-\left(a+b\right)=-a-b[/tex]
[tex]-\left(130+25x\right)=-130-25x[/tex]
[tex]=x\left(88-x\right)-130-25x[/tex]
[tex]x(88-x):88x-x^2[/tex]
[tex]=88x-x^2-130-25x[/tex]
[tex]88x-x^2-130-25x =-x^2+63x-130[/tex]
Therefore, the profit if the cost of producing [tex]x[/tex] units is [tex]-x^2+63x-130[/tex], and there may be restrictions depending on conditions.

6 bananas cost the same as 4 oranges. 3 lemons cost the same as 1 orange. 2 limes cost the same as 1 lemon. How many limes cost the same as 1 banana?
If 6 bananas cost the same as 4 oranges. 3 lemons cost the same as 1 orange, one lime costs the same as half of one banana.
Let's assume the cost of one banana is represented by "B" and the cost of one orange is represented by "O". Based on the given information:
6 bananas cost the same as 4 oranges: 6B = 4O
3 lemons cost the same as 1 orange: 3L = 1O
2 limes cost the same as 1 lemon: 2L = 1O
Now, we need to find the cost of one lime in terms of bananas:
From equation 3, we can rewrite it as: L = (1/2)O
Substitute the value of O from equation 2 into the above equation: L = (1/2) * 3L
Now, we have the cost of one lime in terms of lemons. From equation 2, we know 3 lemons cost the same as 1 orange, so we can rewrite it as: L = (1/2) * (1/3)O
Now, substitute the value of O from equation 1 into the above equation: L = (1/2) * (1/3) * 6B
L = (1/2)B
Therefore, one lime costs the same as half of one banana.

PLEASE HELP ME!!! jacky starts biking to meet up with her friend. she knows that if she bikes at a speed of 10 mph, she will be 3 minutes late. jacky also know that if she bikes at a speed of 12 mph, she will be there 2 minutes before they agree to meet. how much time does she have left before the appointed time?
Answer:
27s
Step-by-step explanation:
d = distance to rendezvous point in miles
t = time of arrival at 10mph, i.e. 3 mins later than appointed time
10 mph = 10 miles per hour = ¹/₆ miles per min
12 mph = ¹/₅ miles per min
t = d/(¹/₆)
t = 6d
5 min = ¹/₁₂ hr
t - ¹/₁₂ = d/(¹/₅)
t = 5d + ¹/₁₂
Elimination of t:
6d = 5d + ¹/₁₂
d = ¹/₁₂ mi
t = 6(¹/₁₂)
t = ¹/₂ min
Time left to appointed time = ¹/₂ - ³/₆₀
= ¹⁰/₂₀ - ¹/₂₀
= ⁹/₂₀.min → 27 seconds
Answer:
27 min
