I got some money for my birthday. I save and spend in the ratio 2:3. I save £32. How much money did I receive for my birthday?
Answer:
80 i think
Step-by-step explanation:
32.3=80
Step-by-step explanation:
Amount of money saved : spent = 2 : 3.
Since amount of money saved = £32,
Amount of money spent = £32 * (3/2) = £48.
Total amount of money = £32 + £48 = £80.
Therefore I received £80 for my birthday.

If x²-2=2⅔ +2-⅔
then prove that 2x³-6x =5 solve and send photo please
Answer:
Step-by-step explanation:
x²-2=2⅔ +2-⅔
x^2 = 2^1 + 2⅔ +2-⅔
x^2 = 4.21736
x = 2.0536.
Plug this into 2x^3 - 6x:
= 2(2.0536)^3 - 6(2.0536)
= 5
So 2x^3 - 6x = 5.
answer:
[tex]x1 = - \sqrt{6} \\ x2 = \sqrt{6} [/tex]
Step-by-step explanation:
[tex]x ^{2} - 2 = \frac{8}{3} + 2 - \frac{2}{3} [/tex]
[tex]x^{2} - 2 = 4[/tex]
[tex]x^{2} = 4 + 2[/tex]
[tex]x^{2} = 6[/tex]
[tex]x = - \sqrt{6} \\ x = \sqrt{6} [/tex]
[tex]x1 = - \sqrt{6} \\ x2 = \sqrt{6} [/tex]
Factorise x^2+13x+12
Step-by-step explanation:
Given
x² + 13x + 12
= x² + ( 12 + 1) x + 12
= x² + 12x + x + 12
= x ( x + 12 ) + 1 ( x + 12)
= (x + 12) (x + 1)
Hope it will help :)❤
HELP???? PLEASE AND FAST IM ON THE BRINK OF DEATH --
Determined to finish her milkshake before Diego, Lin now drinks her 12 ounce milkshake at a rate of 1/3 an ounce per second.
Diego starts with his usual 20 ounce milkshake and drinks at the same rate as before, 2/3 an ounce per second.
1) Graph this situation on
2) What does the graph tell you about the situation and how many solutions there are?
Answer:
See below.
Step-by-step explanation:
Create a system of equations to represent this scenario.
Lin: 12 - 1/3x = yDiego: 20 - 2/3x = y1) A graph of these equations is attached below. Lin is in red; Diego is in blue.
2) The time (seconds) is on the x-axis, while the milkshake (oz) is on the y-axis. The graph shows the rate of change that the volume of the milkshake is decreasing for both Lin and Diego. The intersection point tells us at what time t (s) Lin and Diego have the same amount of milkshake left.
There is only one solution to this system of equations: (24, 4). This tells us that at t = 24 s, Lin and Diego both have 4 oz of milkshake left.
The zeros, aka where the graph touches the x-axis, tell us at what time Lin and Diego finish their milkshakes.
Lin finishes her milkshake later than Diego, at t = 36 s (36, 0), while Diego finishes his milkshake at t = 30 s (30, 0).
select all the expressions equivalent to 5x + 6x + 3x : 11x + 3x, 14x + x, 2 (3x + 4x), 3x(2 + 1) + 5x, 5x + 3(2x + x)
Step-by-step explanation:
5x + 6x + 3x
= 14x.
Now we compare the expressions with the result:
11x + 3x = 14x. (correct)
14x + x = 15x. (incorrect)
2(3x + 4x) = 2(7x) = 14x. (correct)
3x(2 + 1) + 5x = 3x(3) + 5x = 9x + 5x = 14x. (correct)
5x + 3(2x + x) = 5x + 3(3x) = 5x + 9x = 14x. (correct)
Hence our answers are the 1st, 3rd, 4th and 5th.

From stations A and B, the distance between which is 910 mi,
two trains left simultaneously moving towards each other. The
speed of one train was 10 mph greater than the speed of the
other one. In 5 hours the trains met. Find the speed of each train.
Answer:
The slowest train goes at 86 mph and the fastest train goes at 96 mph.
Step-by-step explanation:
Distance and Speed
Assume x is the speed of the slowest train, therefore the speed of the fastest train is x+10.
The distance is calculated as:
d = vt
Where v is the speed and t is the time.
The distance traveled by each train in 5 hours is:
Slowest: 5x
Fastest: 5(x+10)
The sum of both distances is 910 miles:
5x + 5(x + 10) = 910
Operating:
5x + 5x + 50 = 910
10x = 910 - 50 = 860
x = 860/10
x = 86
The slowest train goes at 86 mph and the fastest train goes at 96 mph.
Please give me the correct answer
How do I fine x to the nearest tenth ??
Answer:
x = 13.6
Step-by-step explanation:
Here, we want to find the value of x
to find the value of x. we are going to use the sine rule
It states that the ratio of the sine of an angle to the measure of the side facing the angle is fixed for a triangle
In this case;
11/ sin 27 = x/ sin 34
x = 11 sin 34/sin 27
x = 13.6

On the first visit to the veterinarian's office, Elijah's puppy weighed 19 ounces. On the 2nd visit, the puppy had gained 9 ounces. On the third visit, the puppy had gained another 7 ounces. What is the percent increase since the first visit in the puppy's weight rounded to the nearest percent?
a 84%
b 85%
c 79%
d 81%
Answer:
A)84%
Step-by-step explanation:
Orgin: 19 ounces
Second visit: 19+9=28 ounces
Third visit=28+7=35 ounces
35-19=16 ounces gained
16/19=84.2%=84% increase
A population of 249 birds increases at a rate of 16% annually. jewel writes and exponential function of the form f(x)=abc to represent the number of birds after x years. Which values should she use for a and b
Answer:
a = 249 and b = 1.16
Step-by-step explanation:
Consider the provided information.
The exponential function for growth is: [tex]y=a(1+ r)^x[/tex]
Here, a is the initial value and r is the rate of change.
It is given that the number of birds is 249.
It means a = 249
The rate is given 16%
r=0.16
Put the value of a and r in the above formula.
[tex]y=249(1+0.16)^x[/tex]
[tex]y=249(1.16)^x[/tex]
Now we will compare it with the exponential function form [tex]y=ab^x[/tex]
Therefore, a = 249 and b = 1.16

The values of m and n are whole numbers greater than 1. Which is true about the quotient
Answer:
"The expression will always equal m" is true about the quotient of [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex]
Step-by-step explanation:
Let us solve the question
∵ The expression is [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex]
→ In the division of fractions, we change the division to multiplication
and reciprocal the fraction after the division sign
∵ The reciprocal of [tex]\frac{1}{n}[/tex] is [tex]\frac{n}{1}[/tex]
∴ [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex] = [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex]
→ In the multiplication of fractions, we can simplify the terms in
the numerators by the terms in the denominators
∵ There is n in the numerator and denominator
∴ Cancel n up and down
∴ [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex] = [tex]\frac{m}{1}[/tex]
∴ [tex]\frac{m}{n}[/tex] × [tex]\frac{n}{1}[/tex] = m
∴ [tex]\frac{m}{n}[/tex] ÷ [tex]\frac{1}{n}[/tex] = m
∴ The quotient is m
∴ The expression will always equal m

It takes servers in a restaurant 18 minutes to clear and set 9 tables.
At this rate, how long will it take them to clear and set 20 tables
Answer:
40 minutes
Step-by-step explanation:
To find it taes to clear and set one table divide time by the amount of tables. 18/9=2. It takes 2 minutes per table. To find the answer for 20 tables, you have to multiply 20 by 2. It takes 40 minutes to set and clear 20 tables.

3) A skier traveled downhill at a rate of 12 feet per second. If he started at an elevation of 1,200 feet, what is his elevation after one minute?
Answer:
480
Step-by-step explanation:
12 x 60 = 720
1200 - 720 = 480
Answer: 1,920
Step-by-step explanation:
12ft per second, so to find out his elevation after one minute you would have to convert from seconds to minutes. (60 sec = 1 min). So you would do 12*60 to get 720. And since he already started at 1,200 feet, you add 720. So 1,200+720 = 1,920 ft.
