Which of the following numbers ordered from least go gratest?
0.5, 5/8, 65%, 3/5.
Answer:
0.5 3/5 5/8 65%
Step-by-step explanation:
Answer:
Your answer is 0.5, 3/5, 5/8, 65%.
Step-by-step explanation:
Convert all numbers to decimals:
0.5 = 0.5
5/8 = 0.625
65% = 0.65
3/5 = 0.6
Arrange the numbers accordingly: 0.5, 0.6, 0.625, 0.65. Hence, your answer is 0.5, 3/5, 5/8, 65%.

If 30/t = 18/r, then t/r =
Answer:
5/3
Step-by-step explanation:
30/t = 18/r
Multiplying by r both sides,
30*r /t = 18
Dividing by 30 both sides,
r/t = 18/30 = 3/5
So, t/r = 5/3
9514 1404 393
Answer:
t/r = 5/3
Step-by-step explanation:
Every proportion can be written 4 ways. I like to think of them as "upside down and sideways." They are ...
[tex]\dfrac{30}{t}=\dfrac{18}{r}\qquad\dfrac{t}{30}=\dfrac{r}{18}\\\\\dfrac{30}{18}=\dfrac{t}{r}\qquad\dfrac{18}{30}=\dfrac{r}{t}[/tex]
__
Knowing this, you can simply rewrite your proportion as ...
t/r = 30/18
t/r = 5/3
_____
More formally, you could multiply both sides by t/18:
(30/t)(t/18) = (18/r)(t/18)
30/18 = t/r . . . . as above
Reducing the fraction gives ...
t/r = 5/3
__
Additional comments
The usually-recommended procedure for solving something like this is to "cross-multiply" as a first step. That will give ...
30r = 18t
Of course, that is equivalent to multiplying both sides by rt, the product of the denominators.
From here, to get t/r, you need to divide both sides by 18r.
(30r)/(18r) = (18t)/(18r)
30/18 = t/r
The combination of the two steps, multiply by rt, divide by 18r, is equivalent to multiplying by (rt)/(18r) = t/18, as we did above. That is, you can save some work by doing both steps at once--or by simply rewriting the proportion.

What is the density of an object that has a mass of 20 grams and has a length of 8cm and a width of 2cm and a height of 5cm????
Answer:
Volume is the amount of space an object occupies. To determine the volume of any rectangular object, multiply the measurements of length, width, and height.
Volume = Length × Width × Height
Calculate the volume of this rectangular object.
Length = 3 cm
Width = 3 cm
Height = 12 cm
Volume = l × w × h
Volume = 3 cm × 3 cm × 12 cm
Volume = 108 cm3
Notice that the units for volume are cubic centimeters (cm3).
So 8 ÷ 25 = 0.32 and the units would be g/ cm3 . Other units of density could be g/L or g/ml or mg/ cm3 or kg/ m3 and the list could go on and on. Any unit of mass divided by any unit of volume.

Quantos triângulos distintos cada um dos alunos de Julieta puderam formar com esses canudinhos?
Answer:

During a mathematics activity, teacher Julieta distributed to each of her students 4 straws measuring 2 cm, 3 cm, 7 cm and 8 cm. In this activity, Julieta's students had to build triangles with these straws, without cutting them. How many different triangles could each of Julieta's students form with these straws?==========================================================
Triangle inequality theorem says that no any side of a triangle can be longer or equal to the sum the other two sidesGiven measures:
2 cm, 3 cm, 7 cm, 8 cmWe see that:
2+3 < 7 and 2+3 < 8Therefore we can't make triangles with the sides of 2 cm, 3 cm and 7 cm or 8 cm
Possible solutions are:
2 cm, 7 cm, 8 cm3 cm, 7 cm, 8 cmSo we can make two different triangles

Vincent has already finished 5 oil changes today, and can complete more at a rate of 1 oil change per hour. Warren just came on shift, and can finish 2 oil changes every hour. Sometime during the day, the friends will be tied, with the same number of oil changes completed. How long will that take? How many oil changes will Vincent and Warren each have done?
Answer:
Oil changes = 5
Vincent = 10 oil changes
Warren = 10 oil changes
Step-by-step explanation:
Vincent = 5 + h
Warren = 2h
Where,
h = number of oil changes
How long will that take?
Vincent = Warren
5 + h = 2h
5 = 2h - h
5 = h
h = 5
Number of oil changes = 5
How many oil changes will Vincent and Warren each have done?
Vincent = 5 + h
= 5 + 5
= 10 oil changes
Warren = 2h
= 2(5)
= 10 oil changes

The temperature in the morning was -2 degrees. The temperature is dropping at a constant rate, and 4 hours later the temperature is now -22 degrees. How many degrees did the temperature change each hour?
Given:
Temperature in the morning = -2 degrees.
Temperature is dropping at a constant rate.
Temperature after 4 hours = -22 degrees.
To find:
The rate of change of temperature.
Solution:
Let y be the temperature after x hours from the morning.
Temperature in the morning is -2 degrees. It means, the ordered pair is (0,-2).
4 hours later the temperature is now -22 degrees. It means, the ordered pair is (4,-22).
Now, formula for average rate of change or slope is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{-22-(-2)}{4-0}[/tex]
[tex]m=\dfrac{-22+2}{4}[/tex]
[tex]m=\dfrac{-20}{4}[/tex]
[tex]m=-5[/tex]
Therefore, the change in temperature is -5 per hour. It means the permutate is decreasing by 5 degrees per hour.

What is the first step in converting 139,000,000,000,000,000 to a scientific notation?
Move the decimal after the number 1.
O Move the decimal after the number 9.
O Drop all of the zeroes following the number 9.
O Count the number of positions to move the decimal place.
Answer:
i think it is Move the decimal after the number 1.
Step-by-step explanation:
it the text it says
"To convert our example, 602,200,000,000,000,000,000,000, into a scientific notation, the first step is to place a decimal after the digit 6, and then drop all the zeros after the 2. This will leave us with a coefficient of 6.022. Next, to find the exponent, count the number of times you had to move the decimal point until it landed after the first digit of the coefficient. The answer is 23; therefore, the scientific notation is 6.022 x 1023. In cases where the numbers are multiples of 10, only the base number 10 and the exponent can be used. For instance, the number 1,000,000,000, can be written as 109. Now you try it. What is the scientific notation for a light year, which has been estimated at 9,500,000,000,000 km? As you read the information in this lesson, challenge yourself by converting the large numbers into scientific notations."
Awnser:
(C) Move the decimal after the number 1.
Step-by-step explanation:
The correct answer is Move the decimal after the number 1. The first step in converting a large number to a scientific notation is to determine the coefficient, which is always greater than 1 and less than 10.

A cardboard box is shaped like a cube. The length of each side is 15 inches.
What is the surface area of the box, in square inches?
Work Shown:
s = side length = 15 inches
SA = surface area of the cube
SA = 6s^2
SA = 6*15^2
SA = 6*225
SA = 1350
The surface area is 1350 square inches.
Note the formula has us compute the area of each square face, which is s*s = s^2. Then we multiply by 6 since there are 6 identical square faces on the cube.
Answer:
1350 [tex]in^{2}[/tex]
Step-by-step explanation:
A cube has six sides. To find the area of a square, multiply the length by itself:
15 x 15 = 225
Since each side is the same (because the box is a cube), simply multiply 225 by 6 (the number of sides on a cube):
225 x 6 = 1350

Roberto has $200 in spending money. He wants to buy some video games that cost $25.50 each. Write and solve an inequality to find the number of games that Roberto can buy.
Step-by-step explanation: Each game is $25.50 which in math means it has an "x"
So if x=1 then 25.50x says that 1 video game is $25.50
Set up the equation:
200 = 25.50x (divide both sides by 25.50 to isolate the x)
200/25.50 = 7.84
x = 7.84
You can't have 0.84 of a video game, so Roberto can only buy 7 of them. The answer is correct good job!
The number of games that Roberto can buy [tex]\boldsymbol{8}[/tex] video games.
"To understand the calculation, check below."
Solve an InequalityWhen two values are compared, an inequality shows whether one is less than, greater than, or simply not equal to the other.
It's a relation that compares two integers or other mathematical expressions in a non-equal way.
Total amount with Roberto [tex]=\$ 200[/tex]
Let [tex]x[/tex] denotes number of games that Roberto can buy.
Cost of each video game [tex]=\$25.50[/tex]
So,[tex]25.50x\leq 200\\x\leq 7.8[/tex]
Therefore, Roberto can buy [tex]\boldsymbol{8}[/tex] video games.
