If a:b=3:2 find the value of a+b / a-b
State if this triangle is a right triangle, using Pythagoras.
Answer:
yes
Step-by-step explanation:
the Pythagorean Theorem states that
[tex]a^2+b^2=c^2[/tex]
or to me more specific the two shorter side lengths squared added together equal the hypotenuse squared
So basically what im saying is that if this is a right triangle then
[tex]4^2=\sqrt{6} ^2+\sqrt{10} ^2[/tex]
[tex]4^2=16\\\sqrt{6} ^2=6\\\sqrt{10}^2=10\\10+6=16\\16=16[/tex]
The following statement is true therefore it is a right triangle :)

What is the greatest value 20g of flour 3 for 3.50 or 40g of flour for 2 for 9£ which is better for money
Answer:
It is better to buy 20 g of flour 3 for 3.50
Step-by-step explanation:
It is given that 20g of 3 for 3.50
It means 3 packets of 20 g is 3*20 =60
So, 60g is for 3.50
So, 1 g =[tex]\frac{3.5}{60}[/tex]=0.05833 per gram.
Now, let's find unit rate for 40 g of 2 for 9.
2 packets of 40 gram = 2* 40 =80 grams
So, 80 grams costs 9
So, 1 gram =[tex]\frac{9}{80}[/tex] =0.1125
So, it is better to buy 20 g of flour 3 for 3.50

The half-life of Palladium-100 is 4 days. After 12 days a sample of Palladium-100 has been reduced to a mass of 2 mg.
What was the initial mass (in mg) of the sample?
What is the mass 5 weeks after the start?
Answer:
The initial mass of the sample was 16 mg.
The mass after 5 weeks will be about 0.0372 mg.
Step-by-step explanation:
We can write an exponential function to model the situation.
Let the initial amount be A. The standard exponential function is given by:
[tex]P(t)=A(r)^t[/tex]
Where r is the rate of growth/decay.
Since the half-life of Palladium-100 is four days, r = 1/2. We will also substitute t/4 for t to to represent one cycle every four days. Therefore:
[tex]\displaystyle P(t)=A\Big(\frac{1}{2}\Big)^{t/4}[/tex]
After 12 days, a sample of Palladium-100 has been reduced to a mass of two milligrams.
Therefore, when x = 12, P(x) = 2. By substitution:
[tex]\displaystyle 2=A\Big(\frac{1}{2}\Big)^{12/4}[/tex]
Solve for A. Simplify:
[tex]\displaystyle 2=A\Big(\frac{1}{2}\Big)^3[/tex]
Simplify:
[tex]\displaystyle 2=A\Big(\frac{1}{8}\Big)[/tex]
Thus, the initial mass of the sample was:
[tex]A=16\text{ mg}[/tex]
5 weeks is equivalent to 35 days. Therefore, we can find P(35):
[tex]\displaystyle P(35)=16\Big(\frac{1}{2}\Big)^{35/4}\approx0.0372\text{ mg}[/tex]
About 0.0372 mg will be left of the original 16 mg sample after 5 weeks.

In order to take honors-level math, Lisa must have an average of 85 on her math tests. Her scores so far are 85, 70, and 98. What is the
minimum score Lisa needs on the fourth test to get into honors math dass?
A 80
B 84
C. 85
D. 87
Answer:
d) 87
Step-by-step explanation:
to solve this lets set up the equation
[tex]\frac{85+70+98+x}{4} =85\\\frac{253+x}{4} =85[/tex]
then we multiply 4 on both sides
253+x=340
and subtract 253 on both sides
x=87
to double check take the averages
(87+85+70+98)/4=85
ratio to 54 seconds to 2 minutes
Answer:
54/120

Ratio to 54 seconds to 2 minutes is 9 : 20
Ratio Analyses:Find:
Ratio to 54 seconds to 2 minutes
Computation:
We know that,
1 minutes = 60 second
So,
2 minutes = 120 second
Ratio to 54 seconds to 2 minutes = 54 / 120
Ratio to 54 seconds to 2 minutes = 27 / 60
Ratio to 54 seconds to 2 minutes = 9 : 20

Answer:
These are confusing Beth , b/c you have to remember that they will add to 100%
Step-by-step explanation:
so
green = 3* yellow
100% = green + yellow + 35% + 25%
100% = 3* yellow + yellow +60%
40% = 4* yellow
10% = yellow
30% = green
there are 14 purples in the bag , which is 35% of total
14/.35 = 40
there are a total of 40 pins
so
4 are yellow (10% of 40 or 40* 0.1)
12 are green (30% of 40 or 40*0.3)
14 are purple (35% of 40 or 40*0.35)
10 are grey (25% of 40 or 40*0.25 )

1. Employees of a landscaping company built a retaining wall with area 23(3/8) sq ft. They used brick to make the top portion of the wall, which is 8(1/2) feet. What is the total height of the wall? Write an equation to represent the situation. Then solve. Part 2: If the area of the brick portion of the wall is 15(7/12), what fraction of the wall is brick? Write an equation to show your work.
Answer:
a. h = A/w = 2 ³/₄ ft
b. A'/A = 2/3
Step-by-step explanation:
a. What is the total height of the wall? Write an equation to represent the situation. Then solve.
The wall is a rectangle and its area is A = wh where w = width and h = height of wall.
Making h subject of the formula,
h = A/w
Now, Since the area of the retaining wall, A is 23 ³/₈ ft² and its width is the length of the portion of the wall which is brick w is 8 ¹/₂ ft, then
h = A/w
= 23 ³/₈ ft² ÷ 8 ¹/₂ ft
= 187/8 ft² ÷ 17/2 ft
= 187/8 ft² × 2/17 ft
= 187/4 ft² × 1/17 ft
= 187/68 ft
= 2 ³/₄ ft
b. If the area of the brick portion of the wall is 15(7/12), what fraction of the wall is brick? Write an equation to show your work.
Since the area of the brick portion of the wall is A' = 15 ⁷/₁₂ ft² and the total are of the retaining wall is A = 23 ³/₈ ft²
The fraction of the wall that is brick = A'/A
= 15 ⁷/₁₂ ft² ÷ 23 ³/₈ ft²
= 187/12 ÷ 187/8
= 187/12 × 8/187
= 8/12
= 2/3
Answer with Step-by-step explanation:
a) 2 3/4 ÷ 3 = 11/12 feet
11/12 + 11/12 = 1 5/6
Or, you could write an algebraic equation:
2 3/4 ÷ 3 = x. (3x = 2 3/4)
x = 11/12
The height of the brick proportion of the wall is 1 5/6
b)
You know that 8 x 2 is 16. Well, you already know that the whole total of fractions, multiplied together, would probably be less that 1 and less than 1/2.
So, your rounded answer should be 16. Or 16 1/2
c)
Area = 8 1/2 x 2 3/4.
Use Distributive Property to solve the area.
(8 x 2) + (3/4 x 1/2) = x
8 x 2 = 16
3/4 x 1/2 = 3/8
16 + 3/8 = 16 3/8
x = 16 3/8
I think my answer is reasonable because I estimated 16, and 1/2. 3/8 is close to 1/2. That's why my answer is reasonable.

What is the solution for the following system of equations?
2x + y = 7
x - 2y = 6
I got you bro!
Answer:
{x,y} = {4-1}
You might be wondering how I got this, well here are the steps:
System of Linear Equations entered :
[1] 2x + y = 7
[2] x - 2y = 6
Graphic Representation of the Equations :
y + 2x = 7 -2y + x = 6
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = 2y + 6
// Plug this in for variable x in equation [1]
[1] 2•(2y+6) + y = 7
[1] 5y = -5
// Solve equation [1] for the variable y
[1] 5y = - 5
[1] y = - 1
// By now we know this much :
x = 2y+6
y = -1
// Use the y value to solve for x
x = 2(-1)+6 = 4
Solution :
{x,y} = {4,-1}
