Answer:
1/5, 1/2, 3/4
Step-by-step explanation:
I just now this already from experience, but you could covert all of the fractions into a common denominator. For example use 20.
1/5 = 4/20
1/2 = 10/20
3/4 = 15/20
Then you just need to look at the numerators which 4,10,15 would be the order. And then make sure to convert to the original fractions making the final order be 1/5, 1/2, 3/4.

Answer:
in this equation, do (4n-2)+(3n+8)+90=180, add everything up to get, 7n+96=190, sub 96 from both sides and divide by 7, so n=84/7 which becomes n=12
Answer:
4n,-2+90+3n+8=180(linear pair)
8n=180-96
n=84/8=10.5is your answer

Given
-30 = - 0.4 k
30 = 0.4k
k = 30 / 0.4
k = 75
hope it helps :)
Answer:
Simplifying
-38 = -0.4k
Solving
-38 = -0.4k
Solving for variable 'k'.
Move all terms containing k to the left, all other terms to the right.
Add '0.4k' to each side of the equation.
-38 + 0.4k = -0.4k + 0.4k
Combine like terms: -0.4k + 0.4k = 0.0
-38 + 0.4k = 0.0
Add '38' to each side of the equation.
-38 + 38 + 0.4k = 0.0 + 38
Combine like terms: -38 + 38 = 0
0 + 0.4k = 0.0 + 38
0.4k = 0.0 + 38
Combine like terms: 0.0 + 38 = 38
0.4k = 38
Divide each side by '0.4'.
k = 95
Simplifying
k = 95
What is 7 and three tenths minus 5 and seven tenths
Answer:
1.6
Step-by-step explanation:
7 and three tenths = 7 + 3/10 = 7.3
5 and seven tenths = 5 + 7/10 = 5.7
7.3-5.7 = 1.6 or can be written as 1 and six tenths, or 1 and three fifths.

A lawn seed mixture contains three types of seed: bluegrass, rye, and Bermuda. The costs per pound of the three types of seed are 12 cents, 14 cents, and 3 cents, respectively. In each batch there must be at least 25% bluegrass seed, and the amount of Bermuda must be no more than 2/3 the amount of rye. To fill current orders, the company must make at least 6000 pounds of the mixture. How much of each kind of seed should be used to minimize cost
Answer:
612 dollars
Step-by-step explanation:
From the given information:
Amount of the total mixture = 6000 pounds
Also, for each batch, there needs to be at least 25% bluegrass seed.
It implies that:
In 6000 pounds, there are (25×6000)/100 = 1500 pounds of bluegrass seed.
The remaining amount of (6000 - 1500 = 4500)pounds will be for rye and Bermuda.
Suppose the amount of rye seeds = x pounds
while that of Bermuda is (4500 - x) pounds
Then, since the amount of Bermuda contains no more than 2/3 of that of rye.
The equation can be written as:
[tex]( 4500 - x) = \dfrac{2x}{3}[/tex]
13500 - 3x = 2x
13500 = 5x
[tex]x = \dfrac{13500}{5}[/tex]
x = 2700
Now, the amount of rye seed = 2700 pounds
while that of Bermuda seed = 4500 - 2700 = 1800 pounds
However, For Bluegrass, we are told that the cost of 1 pound is 12 cents.
So, the cost of 1500 bluegrass seeds = 12 × 1500 = 18000 cents
For rye seed; cost of 1 pound = 14 cents
the cost of 2700 rye seeds = 14 × 2700 = 37800 cents
For Bermuda seed; cost of 1 pound = 3 cents
the cost of 1800 rye seeds = 3 × 1800 = 5400 cents
The total amount = (18000 + 37800 + 5400) = 61200 cents
Recall that:
100 cents = 1 dollars
61200 cents = x dollars
x = 61200 cents/100 cents
x = 612 dollars
Thus, the minimum cost is 612 dollars.

Agatha borrowed $4,500 from the bank. 4 years later, Agatha owes the bank $5,040. What was the percentage rate of simple interest in the loan?
Answer:
12%
Step-by-step explanation:
If we subtract both numbers we get 540.
[tex]\frac{540}{4500} = \frac{x}{100} \\[/tex]
540 x 100 = 54,000
54,000 / 4,500 = 12%
Work out the percentage change to 2 decimal places when £78.98 is increased to £100
Answer:
Percentage change = 26.61 %
Step-by-step explanation:
Given
Initial value = £78.98Final value = £100To determin
Percentage change = ?
Using the formula
Percentage change = (Final value - Initial value) / | Initial Vaue | × 100%
= (100 - 78.98) / 78.98 × 100%
= [21.02/78.98] × 100%
= 0.266143 × 100%
= 26.6143 %
Rounding off to 2 decimal places
= 26.61 %
Therefore,
Percentage change = 26.61 %
IN triangle ABC point D is the centroid and BD=4 Find BE
Answer:
2
Step-by-step explanation:
What is so special about the centroid? It is the distinct point that each of the three medians intersect. Therefore, from this definition we can figure out through some geometric proof (I'm not going to go into this) the following:
If you draw the medians, you will notice that they intersect at exactly one point. That is the centroid. You will also notice that the centroid splits the median into 2 parts: top and bottom. The proof suggests that the top part is 2 times the bottom part.
In this case, the centroid is D and the top point is B. Therefore, we can figure out that BD, the top part, must be 2 times the bottom part, which is BE. Thus, we determine that BE is 2 because 4/2 = 2.
I would encourage you to draw it out so you can understand. Unfortunately, typing may not work all the time
X + 14 = 56 What would I do to both sides to answer this equation? O Multiply both sides by 14 © Subtract both sides by 14 Subtract both sides by 14 Add both sides by 14
To solve for X in this equation, you would subtract both sides by 14 because our goal is to get X on its own. If we write it out, we see that
X + 14 - 14 = 56 - 14
X=42
Because we have a positive 14, a negative 14 will average out to be 0, but what you do to one side, you must do to the other.
If you have any more questions, feel free to ask!
How do you create and solve equations in one variable given a real–world situation?
Step-by-step explanation:
1) first eliminate constant(number without variable) you eliminate constant by doing the inverse operation(if constant is being added, then subtract)(if constant is being subtracted, then add it)
ex: if x+9=32
subtract 9 from both sides to get rid of it
x=23
2) if there is another constant but this constant is being multiplied/divided then do the opposite operation to remove it
you could multiply by 3 on both sides:
x+9=69
x=60

Answer:
the surface area is 75m square.
Step-by-step explanation:
The surface area of a prism is 136 m².
What is Surface Area?The area is the space occupied by a two-dimensional flat surface. It is expressed in square units. The surface area of a three-dimensional object is the area occupied by its outer surface.
Given:
First, the Area of Bottom:
= l x w
= 6 x 7
= 42 m²
Second, the Sides are
= 5 x 7 x 2
= 70 m²
and, the area of Triangles:
= 2 x 1/2 x b x h
= 2 x 1/2 x 6 x 4
=24 m²
Thus, the total Surface Area
= 42 + 70 + 24
= 136 m²
