Answer:
A: 4/8
Step-by-step explanation:
1/2 is the same as 4/8 because if we divide 4 to both the numerator (4 divided by 4) and the denominator (8 divided by 2), we get 1 for the numerator and 2 for the denominator.

Ecuacion del siguiente problema: Por 12 envases de plastico de un litro y 5 envases de medio litro de aceite para motor me cobran 92.00 pesos
Answer:
92. p = 12l + 5m donde m = 0.5 l
Step-by-step explanation:
Supongamos que el recipiente de un litro se denota por ly el recipiente de medio litro se denota por m (= 0,5 l), entonces la ecuación se puede escribir como
92. p = 12l + 5m donde m = 0.5l
English
Let the one liter container be denoted by l and half liter container be deonted by m(= 0.5l ) then the equation can be written as
92. p= 12l + 5m where m = 0.5l

A triangle has two sides of length 13 and 8. What compound inequality describes
the possible lengths for the third side, x?
Write a compound inequality like 1
Answer:
5 < x < 21
Step-by-step explanation:
The shortest would be if the 8 leg folded back on the 13 leg
13 - 8 > 5
The logest would be if the 8 leg extended the 13 leg
13 + 8 < 21
Therefor
5 < x < 21

Answer:
I believe, by process of elimination, it is "Kara's fee for the second child is $5"
Step-by-step explanation:
It can't be the second option because if her hourly rate for 2 kids was 14, then on hour 2 the total would be $28.
It can't be the third option because Jill's pattern is $11 dollars an hour, and Kara's is adding $9. So, by hour 4, Jill would make $44 and Kara would make $41.
Lastly, it can't be the 4th option because 11-9=2. 2 does not equal 3.

Points A and B are the endpoints of an arc of a circle. Chords are drawn from the two endpoints to a third point, C, on the circle.
Given and ,
° and
°.
Answer:
146°
Step-by-step explanation:
Points A and B are the endpoints of an arc of a circle. Chords are drawn from the two endpoints to a third point, C, on the circle. Given m arch AB=64° and ⦣ABC=73°, m ⦣ABC=__ ° and m arch AC=__ °.
Solution:
Given that:
arc AB = 64° and ⦣ABC=73°
The Central Angle Theorem states that the central angle from two chosen points A and B on the circle is always twice the inscribed angle from those two points. The inscribed angle is any point along the outer arc AB and the two points A and B.
Therefore arc AC is the central angle of ⦣ABC. Using the central angle theorem gives:
arc AC = 2 * ⦣ABC
substituting:
arc AC = 2 * 73
arc AC = 146°

Answer:
D.0
Step-by-step explanation:
If you graph the equation you can see that it doesn't cross the x-axis. It doesn't go lower than y=1. If you don't have a graphing calculator use Desmos. Also the +1 at the end of the equation tells you that it won't go lower than y=1.
Answer:
Never your answer is 0
Step-by-step explanation:
The equation creates what's called a parabola the line curves up the 1 represents the y axis so the line curves up from the y axis point 1 never touching the x axis

Answer:
57º
Step-by-step explanation:
A triangle equals 180º so to find x, just subtract the other angles from 180
180 - 39 - 84 = 57
Step-by-step explanation:
x+39+84=180 (being sum of angle of triangle is 180)
x+123=180
x=57
Place the following in order from least to greatest. 8,000,000 mm, 5 km, 7000,000 cm, 6,000 m
Answer: 5km, 6000m, 8,000,000 mm, 7000000 cm
Step-by-step explanation:
Note that:
1km = 1,000,000mm
1m = 1000mm
1cm = 10mm
Therefore,
5 km = 5 × 1,000,000mm = 5,000,000mm
7000,000 cm = 7,000,000 × 10 = 70,000,000mm
6,000 m = 6000 × 1000 = 6,000,000mm
Therefore, from the least to the greatest will be:
5km, 6000m, 8,000,000 mm, 7000000 cm

How much Zn and how much HCl should be used to produce 1.5 g ZnCl2
Answer:
0.71963 g of Zn0.80256 g of HClStep-by-step explanation:
The required mass of reactants can be computed from the number of moles of product.
moles of ZnCl₂ = (1.5 g)/(136.282 g) ≈ 0.0110066 moles
Then the mass of Zn required is ...
mass of Zn = (0.0110066 mol)(65.382 g/mol) = 0.71963 g
Two moles of HCl are used in the reaction with each mole of Zn, so the mass of HCl required is ...
mass of HCl = 2(0.0110066 mol)(36.458 g/mol) = 0.80256 g
_____
Comment
The discrepancy in the last two decimal places of the weights above versus the calculator output below comes from rounding of moles of Zn to 4 significant digits, instead of 5 or more. The number of moles of ZnCl₂ is closer to 0.0110066.
Find the volume of a right circular cone that has a height of 5.2 m and a base with a
radius of 15. 3 m. Round your answer to the nearest tenth of a cubie meter.
Answer:
1274.7 cubic meters
Step-by-step explanation:
Because the equation to find volume of a cone is V = πr²(h/3), you would have to plug in your values which are h = 5.2m, and r = 15.3m. Once you do the math you will get 1274.72 cubic meters, or 1274.7 when rounded to the nearest tenth.
