Answer:
x = number of text messages sent
0.2x+40=50
0.2x = 10
5(0.2x) = 5(10)
x = 50
Therefore, 50 text messages would have to be sent or received in order for the plans to cost the same each month.

if y varies inversely as x and y=16 when x=4, find y when x=3
Answer:
21.33 to nearest hundredth
Step-by-step explanation:
Inverse Variation is y = k / x where k is a constant.
Plug in the given values to find k:-
16 = k/4
k = 4*16 = 64 so the equation of variation is y = 64/x.
So when x = 3, y = 64/3 = = 21.33 to nearest hundredth.
The value of y when x = 3 is 21.33
The value of y = 21.33
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be A
The value of x = 4
The value of y = 16
Now , the value of y is inversely proportional to x
So ,
y ∝ 1/x
y = k/x
where k is the constant of proportionality
So , k = yx
Now , substituting the value of x and y in the equation , we get
k = 16 x 4
k = 64
So , when the value of x = 3 ,
y = k / x
y = 64 / 3
y = 21.33
Hence , The value of y when x = 3 is 21.33

2m^2+2m-12=0 in vertex form
Answer:
y = 2(m + 1/2)^ -25/2
Step-by-step explanation:
vertex form is:
y = 2m^2 + 2m - 12
y + 12 + ( )___ =( ) 2m^2 + 2m + ___
Because a is not one, you must divide the entire right side by the a value, which is 2. Then place the 2 in the parenthesis.
y + 12 + (2)__ = (2) m^2 + m + __
Take half of b, b being one.
Half of be is 1/2. Now square it to get 1/4. Place that value in the blanks.
y + 12 + (2)1/4 = (2) m^2 + m + 1/4
Now simplify the left side and factor the right side.
y+ 12 + 1/2 = 2(m + 1/2)^2
y + 25/2 = 2(m + 1/2)^2
Subtract 25/2 from both sides.
y = 2(m + 1/2)^ -25/2

Catalina uses a 3 1/2 ounce packet of seasoning for her steaks. The packet contains of 1 1/3 ounces of garlic powder and 1 1/4 ounces of onion powder. The remainder of the packet consists of black pepper. How many ounces of black pepper are in the packet of seasoning?
Answer:
11/12
Step-by-step explanation:you have to turn all the mixed numbers into improper fraction so 1 1/3 is 16/12 1 1/4 is 15/12 and if you add them you get 2 7/12 and that minus 3 6/12 is 11/12
There are 11/12 ounces of black pepper in Catalina's seasoning packet.
Catalina uses a 3 1/2 ounce packet of seasoning for her steaks.
This packet contains 1 1/3 ounces of garlic powder and 1 1/4 ounces of onion powder.
To find out how many ounces of black pepper are in the packet, we need to subtract the combined weight of the garlic and onion powders from the total weight of the seasoning packet.
Garlic powder: 1 1/3 ounces = 4/3 ounces
Onion powder: 1 1/4 ounces = 5/4 ounces
Total seasoning packet: 3 1/2 ounces = 7/2 ounces
We then add the amounts of garlic and onion powders to get their combined weight:
4/3 + 5/4 = (16 + 15) / 12 = 31/12 ounces
The next step is to subtract the combined weight of the garlic and onion powder from the total weight of the seasoning packet:
7/2 ounces - 31/12 ounces = (7\*6 - 31) / 12 = (42 - 31) / 12 = 11/12 ounces.

What is the unit rate for $12.50 for 5 ounces?
Answer:
The correct answer is $2,50.
Step-by-step explanation:
The unit rate is what we use to determine the price of a single unit, when something is sold in a group, as in this case 5 ounces.
We have been told that $ 12.50 is the price for 5 ounces, but what we want to know is how much 1 ounce costs.
To determine this, what we must do is divide the total price by the quantity of ounces, in order to determine the unit price:
12.50 / 5 = 2.50
In this way we can verify that the unit price of 5 ounces is $ 2.50
The correct answer is $2,50, is the unit rate for $12.50 for 5 ounces.

Given: KLMN is a trapezoid, m∠N=m∠KML, FD=8, LM KN = 3/5 F∈ KL , D∈ MN , ME ⊥ KN KF=FL, MD=DN, ME=3root5 Find: KM
Answer:
The length of KM is [tex]\sqrt{109}[/tex] units.
Step-by-step explanation:
Given the statement: KLMN is a trapezoid, ∠N= ∠KML, FD=8, [tex]\frac{LM}{KN}=\frac{3}{5}[/tex], F∈ KL, D∈ MN , ME ⊥ KN KF=FL, MD=DN, [tex]ME=3\sqrt{5}[/tex].
From the given information it is noticed that the point F and D are midpoints of KL and MN respectively.
The height of the trapezoid is [tex]3\sqrt{5}[/tex].
Midsegment is a line segment which connects the midpoints of not parallel sides. The length of midsegment of average of parallel lines.
Since [tex]\frac{LM}{KN}=\frac{3}{5}[/tex], therefore LM is 3x and KN is 5x.
[tex]\frac{3x+5x}{2}=8[/tex]
[tex]\frac{8x}{2}=8[/tex]
[tex]x=2[/tex]
Therefore the length of LM is 6 and length of KN is 10.
Draw perpendicular on KN form L and M.
[tex]KN=KA+AE+EN[/tex]
[tex]10=6+2(EN)[/tex] (KA=EN, isosceles trapezoid) [tex]EN=2[/tex]
[tex]KE=KN-EN=10-2=8[/tex]
Therefore the length of KE is 8.
Use Pythagoras theorem is triangle EKM.
[tex]Hypotenuse^2=base^2+perpendicular^2[/tex]
[tex](KM)^2=(KE)^2+(ME)^2[/tex]
[tex](KM)^2=(8)^2+(3\sqrt{5})^2[/tex]
[tex]KM^2=64+9(5)[/tex]
[tex]KM=\sqrt{109}[/tex]
Therefore the length of KM is [tex]\sqrt{109}[/tex] units.

The temperature at the mountain base camp dropped from -5 degrees Celsius on Wednesday to -7 degrees Celsius Thursday morning, and finally to -8 degrees Celsius on Thursday evening.
Explanation:To solve this, we first have to know the temperature on Wednesday, which is −5 degrees Celsius. On Thursday morning, the temperature was 2 degrees Celsius lower than Wednesday, so we subtract 2 from -5 which gives us -7 degrees Celsius. By Thursday evening, the temperature had dropped another 1 degree Celsius, so we subtract 1 from -7, resulting in a base camp temperature of -8 degrees Celsius.

What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x = 4 is an equation
2x + 4y = 6 is an equation.
We have,
Total number of students = 124
Number of boys = x + 12
Number of girls = x
Now,
x + 12 + x = 124
2x + 12 = 124
Subtract 12 on both sides
2x = 124 - 12
2x = 112
Divide 2 on both sides.
x = 56
The number of boys.
= x + 12
= 56 + 12
= 68
The number of girls.
= 56
Thus,
The number of boys is 68
The number of girls is 56

Explanation:
Finding the totals of each column and row, we find:
There are 3+2+1 = 6 children in the baseball league.
There are 7+2+1 = 10 children in the softball league.
There are 3+7 = 10 children in the 7-9 division.
There are 2+2 = 4 children in the 10-12 division.
There are 1+1 = 2 children in the 13-15 division.
There are a total of 10+6 = 16 children.
We start with the information that the team is a member of the softball league. There are 10 children in this league; this is the denominator of the probability.
There are 7 children in the 7-9 division that are in the softball league. This gives us the probability 7/10.

Bank of Peace= 15000(1+0.025)³=£16153.36
Bank of Trust=15000(1+0.038)=£15570
£15570(1+0.01)=£15882.95
Bank of Peace is the best choice.
I would choose the Bank of Peace to get the most of my savings.
Formula for calculating the compound value of the savings at the Bank of Peace = FV = P (1 + r)^n
FV = Future value
P = amount deposited
R = interest rate
N = number of years
£15,000 x (1.025)^3 = £16,153.36
Interest earned at the Bank of Trust in the first year = £15,000 x 0.038 = $570
Total amount at the end of the first year = $570 + £15,000 = £15,570.
