Suppose that 19 inches of wire costs 76 cents. At the same rate, how many inches of wire can be bought for 48 cents?
Answer: 12 inches
Step-by-step explanation:
Because 19 inches costs 76 cents. If you divide 19/19 you get 1 inch. Also divide 76/19 and you get 4 cents. Now it’s asking how many inches could be bought for 48 cents. So 48/4 equals to 12 and that’s your answer. You see 19x4=76. And 12x4= 48. I hope that helped you.

Austin is building a miniature replica of the empire state building. the actual empire state building is 1,423 feet tall and 6,000 feet wide. if Astin's replica has a width of 60 centimeters, what is the hight of his empire state building replica rounded to the nearest centimeter?
60/6000 = x/1423
100/1 = 1423/x
100x = 1423
x = 14.23 --> About 14 cm

Work out the size of angle x
Answer:
Let's name the angle right close to 51 as c.
c = 180°-51° since angles on a straight line is equal to 180°.
so c= 129°
so x = 129° since it corresponds to c
Answer:
Step-by-step explanation:
Notice that the line that the variable x is on is equal to 180 degrees. Because the angle that it is next to is equal to 51 degrees, you subtract 180 from 51:
180-51=129
The final answer to this problem is 129 degrees.
In the polynomial shown in the graph below, are there any places that could be described as either a local minimum or local maximum? Neither? Both?
Answer:
Local Min and Local Max
Step-by-step explanation:
Since our end behavior of our graph is goes on to infinity and negative infinity, we know that we will not have an absolute min or max. However, we will have relative/local min and max.
The local min and max are mins and maxes relative to the surrounding points. We see that our local min would happen around x ≈ 0.75 and our local max will happen at x ≈ -1.9.

The length of cell A is 8x10 to the power of negavtive 6 m. The length of cell B is0.0000004 m. What is the ratio of cell A's length to cell B's length? Use pencil and paper. Is it easier to find the ratio when the numbers are expressed in scientific notation or in standard form? Explain your reasoning.
Answer:
Ratio of length of cell A to cell B is 20 : 1
Step-by-step explanation:
Length of cell A = [tex]8\times 10^{-6}[/tex] m
Length of cell B = 0.0000004 m
Convert the length of cell B into scientific notation.
Length of cell B = [tex]4.0\times 10^{-7}[/tex]
Now the ratio of the lengths of cell A and cell B = [tex]\frac{8.0\times 10^{-6}}{4.0\times 10^{-7}}[/tex]
= [tex]2\times 10^{7-6}[/tex]
= 20
Therefore, ratio of length of cell A to cell B is 20 : 1
Places A and B are 100km apart from each other on a highway. A car starts from A and another from B at the same time. If they move in the same direction, they meet in 10 hours and if they move in opposite directions, they meet in 1 hour and 40 minutes. Find the speeds of the cars.
Answer:
Speed of the first car = x = 35km/hr
Speed of the second car = 25km /hr
Step-by-step explanation:
The calculation of speeds of the cars is given below:-
Assume that the speed of the 1st car which is opening from A = x km/hr
and assume the Speed of the 2nd car which is starting from B
= y km/hr
As we know that
Time = Distance ÷ Speed
So, the distance lies between two places i.e. A and B are
80km d = 80 km
1. now when the car moves in the similar direction
So, the corresponding speed of them = (x + y)km/hr
Time = 8hr
d = 80km
[tex]8 = \frac{80}{(x + y)}\\\\x + y = \frac{80}{8}\\\\x + y = 10 ..... (i)[/tex]
2. when two cars moving in the inverse direction,
So, the corressponding speed = (x - y) km / hr
Time = 1 hr 20 minutes
That means
= (1 + 20 ÷ 60) hr
= (80 ÷ 60)
= 4/3 hr
d = 80km
Now
4 ÷ 3 = 80 ÷ (x -y)
x -y = (80 × 3) ÷ 4
x - y = 60 ..... (ii)
Now, we will sum equation 1 and equation 2 we will get
2x = 70
x = 35
now, Put x = 35 in (i) we will get
y = 25
Speed of the first car = x = 35km/hr
Speed of the second car = 25km /hr

Logan has two aquariums. One aquarium contains 1.3 cubic feet of water and the other contains 1.9 cubic feet of water. The water in the larger aquarium weighs 37.44 pounds more than the water in the smaller aquarium. Write an equation with a variable on both sides to represent the situation. Then find the weight of 1 cubic foot of water.
Answer:
62.4
Step-by-step explanation:
1. 1.3x+37.44=1.9x
2. 1.3x+37.44-1.3x=1.9x-1.3x
0.6x=37.44
3. x=37.44/0.6=62.4
The weight of 1 cubic foot of water is 62.4 lb.
Representing Equation with variable on both sides
Let 'x' pounds be the weight of 1 cubic foot of water.
We know one aquarium contains 1.3 cubic feet of water. So, the weight of 1.3 cubic feet of water = 1.3x
The other aquarium contains 1.9 cubic feet of water. So, the weight of 1.9 cubic feet of water = 1.9x
It is given in the question that the water in the larger aquarium weighs 37.44 pounds more than the water in the smaller aquarium.
The equation would be
1.9x = 1.3x + 37.44
The above equation quality the condition of variable on both sides.
To find out the weight of 1 cubic foot of water, we will solve the above equation to find the value of x.
1.9x = 1.3x + 37.44
1.9x - 1.3x = 37.44
0.6x = 37.44
x = 37.44/0.6
x = 62.4
So, the weight of 1 cubic foot of water is 62.4 lb.

What is an equation of the line that passes through the point
(-6, -2) and is parallel to the line 3x – 2y = 2?
Answer: y=3/2x+7
Step-by-step explanation:
To find the equation of the line that passes through the given point, let's first convert the given equation to slope-intercept form.
3x-2y=2 [subtract both sides by 3x]
-2y=-3x+2 [divide both sides by -2]
y=3/2x-1
Now that we have the equation in slope-intercept form, we know that the slope must stay the same because parallel lines NEVER touch. All we have to do is plug in the given point to find the y-intercept.
-2=3/2(-6)+b [multiply]
-2=-9+b [add both sides by 9]
b=7
Now, we know that the parallel equation is y=3/2x+7.
