Step-by-step explanation:
3x+14=65 which is telling you that 3 times a number which is unknown so we will call it x and add 14 equals 65. when you work it out you should get the total which is 65. so the way you work that out is you separate everything without an x to the right side of the equation which looks like 3x=65-14 then work it out subtract 14 from 65 and you get 3x=51 )which is total spent on 3 games. Then you divide 3x/3= 51/3 then the 3s cancel our so you have x=51/3 and when you work that out you get your answer x=17 which is the cost per game.
Edward has a box of following Skittles: 5 red, 4 green, 6 orange, 3 purple, and 7 yellow. He wants to know what the probability of choosing a red Skittle, eating it, and then choosing a yellow Skittle is. Which expression below shows Edward how to correctly find the probability of this situation? Skittles Original O 7/25 x 4/25 5/25 x 7/25 5/25 x 7/24 05/24 x 7/24
Answer:
Let's add the total skittles to get our outcome:
25 in total.
5(red skittles)/25(total skittles in all)
7(yellow skittles)/24(total skittles in all NOW since you took a red skittle)
So therefore your expression is:
5/25 x 7/24
calculate the compound interest on an investment of R6500 at 7,5% per annum invested for 3 years
Answer:
Compound interest = Rs 1,575 (Approx.)
Step-by-step explanation:
Given:
Amount invested = R.s 6,500
Rate of interest = 7.5% per annum
Number of year = 3 year
Find:
Amount of compound interest
Computation:
Compound interest = P[(1+r)ⁿ - 1]
Compound interest = 6500[(1+7.5%)³ - 1]
Compound interest = 6500[(1+0.075)³ - 1]
Compound interest = 6500[(1.075)³ - 1]
Compound interest = 6500[1.2423 - 1]
Compound interest = 6500[0.2423]
Compound interest = 1574.95
Compound interest = Rs 1,575 (Approx.)

Find the number of moles of Argon in 97.37 grams.
Answer:
n = 2.43 moles
Step-by-step explanation:
Given mass, m = 97.37 grams
The mass of Argon is, M = 39.948 g/mol
We know that,
No. of moles = given mass/molar mass
[tex]n=\dfrac{97.37}{39.948}\\\\n=2.43\ moles[/tex]
Hence, there are 2.43 moles of Argon.

A certain television is advertised as a 59-inch TV (the diagonal length). If the width of
the TV is 49 inches, how tall is the TV? Round to the nearest tenth of an inch.
Answer:
32.9 inches
Step-by-step explanation:
this can be solved using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base = 49
c = hypotenuse = diagonal = 59
l² + 49² = 59²
l² = 59² - 49²

What is the range of 10, 20, 5, 6, 7, 8, 15, 17
Answer: 15
Step-by-step explanation: Line them up from smallest to largest. 5, 6, 7, 8, 10, 15, 17, 20. Then do the largest number minus the smallest number. In this case, its 20 - 5. That equals 15, so thats your answer

Answer:
15.2 cm, 130 m
Step-by-step explanation:
1. The sine of angle Z is XY/17.4; (opposite/hypotenuse);
sin(61) = XY/17.4; multiply both sides by 17.4 to find XY
17.4sin(61) = 15.2 cm

This triangle is made by the anchor of the balloon to the ground, the balloon, and the area on the ground directly below the balloon.
The hypotenuse of the triangle is the 170 m string.
The angle of inclination is 50 degrees.
The height of the triangle will be opposite of the angle of inclination.
Therefore,
sin(50) = height/170 (opposite/hypotenuse)
170sin(50) = 130.2 meters
Suma masurilor a doua unghiuri este egala cu 180(de grade). Determinati masura fiecarui unghi stiind ca unul dintre unghiuri are masura egala cu 20% din masura celuilalt unghi
Answer:
150 grados
30 grados
Step-by-step explanation:
Sea x la medida del primer ángulo
Sea la medida del segundo ángulo y
Según la pregunta;
x + y = 180 -------- (1)
De la segunda oración;
x = 0,2 años -------- (2)
Sustituyendo (2) en (1)
0,2 años + y = 180
1,2 años = 180
y = 180 / 1,2
y = 150 grados
Pero;
x = 0,2 años
Entonces
x = 0,2 (150)
x = 30 grados
Por eso;
y = 150 grados
x = 30 grados

Shannon won $200 dollars playing Bingo last week. This week she won
$450. What is the percent of change in her winnings?
55.5% increase
125% decrease
55.5% decrease
125% increase
Answer: 125% increase
Step-by-step explanation: She won 200 dollars last week and now she won 450. If more, less divides. So 450 is more than 200.
This would give you 450/200. You're trying to find percentage so you multiply by a hundred. 450/200 * 100. This will give you 125%

If f(x)=7(x-1)+8f(x)=7(x−1)+8 , what is the value of f(1)f(1) ?
Answer:
8
Step-by-step explanation:
All you have to do is plug in 1 for the x value, which leaves you with the equation 7(1-1) + 8, then you simplify it to be 7(0) + 8
7 times 0 is 0, so you are left with 8 as your answer

Answer:
The answer is option c) 56.5 ft²
Step-by-step explanation:
Area of shaded region =
Area of Big Circle - ( Area of 1st small circle+ Area of 2nd small circle )
Area of 1st small circle:
π x r²
r = 3ft
Area = 3.14 x 3 x 3 => 28.26 ft²
Area of 2st small circle:
π x r²
r = 3ft
Area = 3.14 x 3 x 3 => 28.26 ft²
Area of big circle:
π x r²
r = 6ft ( ∵ Diameter of 1st small circle = 6 and since 2 small circles have equal area, their diameter should be the radius of big circle )
Area = 3.14 x 6 x 6 => 113.04 ft²
Area of shaded region => 113.04 - (28.26 + 28.26 )
=> 113.04 - 56.52
=> 56.52 ft²
The difference of two numbers is 45. Their sum is 55. What are the two numbers?The difference of two numbers is 45. Their sum is 55. What are the two numbers?
Answer:
50, 5
Step-by-step explanation:
X=number 1
x-45=number 2
x+(x-45)=55
2x=100
x=50 number 1
x-45 is number 2
50-45=5 number 2
Simplify the expression. Write your answer as a power.5^8/5^5
Answer:
5^3
Step-by-step explanation:
First, find 5 to the 8th power:
5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 = 390, 625
Then, find 5 to the 5th power:
5 x 5 x 5 x 5 x 5 = 3,125.
Finally, divided the two numbers:
390, 625/3,125 = 125
Now, right this as a power:
5^3
7 - 2x - x4
b) How many terms are there?
c) What is the leading coefficient?
d) What is the constant term?
e) What is the degree of the expression?
Answer:
b) three terms
c) -1
d) 7
e) 4
Step-by-step explanation:
put the expression in decreasing exponent order with the constant at the end
-x⁴ - 2x + 7
With this format it is easy to find the leading coefficient which is the coefficient of the term with the highest exponent; in this case you only see a negative sign but every variable, if no other coefficient is present, has an invisible '1'
A random number from 1 to 5 is selected
50 times. The number 1 is selected 13 times,
2 is selected 8 times, 3 is selected 14 times, 4
is selected 6 times, and 5 is selected 9 times.
What is the relative frequency of selecting a 2?
3?
Answer:
Relative frequency of selecting a 2 = 8/50 = 0.16
Relative frequency of selecting a 3 = 14/50 = 0.28
Step-by-step explanation:
When we have a given experiment with given outcomes (such that each time that we perform the experiment, one outcome happens) the relative frequency of a given outcome is the quotient between the number of times that that outcome happened, and the total number of times that the experiment was performed.
Here the experiment is selecting a random number between 1 and 5, and it is performed 50 times.
Out of these 50 times, the outcome "2" appears 8 times.
Then the relative frequency of selecting the number 2 is:
f(2) = 8/50 = 0.16
And of these 50 experiments, the outcome "3" appears 14 times.
Then the relative frequency of selecting the number 3 is:
f(3) = 14/50 = 0.28

a recipe for pancakes requires 1 3/4 cups of milk. how much milk is needed to get twice as many pancakes
Answer:
7/2 cups of milk.
Step-by-step explanation:
1 3/4=7/4
2(7/4)=14/4=7/2
Answer:
7/2 cups of milk.
Step-by-step explanation:
If you want double the pancakes You must double the amount of milk:
First change it into an improper fraction:
1 3/4=7/4
then multiply it by two and simplify:
2(7/4)=14/4=7/2
