“3 more than 5” written as an algebraic expression is “3+5” which is equal to 8.
In a formula or equation involving mathematical operations, the representation of numbers by alphabet is referred to as algebra. Similar to how a statement explains the link between certain words, algebraic equations describe the connection between unknown variables.
We are given a mathematical statement and have to convert it into an algebraic expression using the information above.
3 more than 5 is obtained after adding 5 to the given number which is 3.
So 3 more than 5 is equal to 3+5=8.
Hence “3 more than 5” written as an algebraic expression is “3+5” which is equal to 8.

A dart board contains 20 equal sized sectors numbered 1 to 20. A dart is randomly tossed at the board 10 times. what is the probability that the dart lands in sector 20 exactly 5 times?
Answer:
1/2
Step-by-step explanation:
There are a total of 20 sections on the board. And a dart hit that the section labeled 20 a total of 5 times, throwing a total of 10 darts. So, if you take these two numbers and and put them into the fraction: 5/10 and then simplify it you will get 1/2. Hope this helps.

A. -√3 +2
B. √2*√3
C. √27*√ 3
D. 3√7 + 2√7-5√7
Answer:
A and B.
Step-by-step explanation:
The irrational number are -√3 +2 and √2 x √3.
What is Irrational Number?Any number that cannot be stated as a fraction for any integers is considered to be irrational. The decimal expansions of irrational numbers are neither periodic nor do they come to an end. Every number that is transcendental is illogical.
Given:
A) -√3 +2 is an irrational number.
B) √2 x √3 = √6, which is an irrational number.
C) √27 x √ 3
= 3√3 x √3
= 3 x 3
= 9, which is a rational number.
D) 3√7 + 2√7-5√7
= 5√7- 5√7
= 0, which is a rational number.

Suppose y varies directly with x, and y = 14 when x = 2. What direct variation equation relates x and y? What is the value of y when x = 6? Explain. Show your work
A. The equation y = 2x relates x and y. When x = 6, y =2(6) or 12.
B. The equation y = 14x relates x and y. When x = 6, y =14(6) or 84.
C. The equation y = 7x relates x and y. When x = 6, y =7(6) or 42.
Answer: C. The equation y = 7x relates x and y. When x = 6, y =7(6) or 42.
Step-by-step explanation:
Using direct variation with the formula:
y = kx
Since y =14, when x = 2.
y = kx
14 = 2k
k = 14/2
k = 7
Therefore, y = 7x
The value of y when x = 6 will be:
y = kx
y = 6k
Recall that k = 7
y = 6 × 7
y = 42
Therefore, the equation y = 7x relates x and y. When x = 6, y =7(6) or 42.

The proportional relationship between the distance driven and the amount of time driving is shown in the
following graph.
Which statements about the graph are true ?
A. The y- coordinate of point A represents the distance driven in 4 hours.
B. The distance driven in 1 hour is 80 km
C. None of the above
The distance driven in 1 hour is 80 km. Therefore, option B is the correct answer.
The given time graph shows the proportional relationship between the distance driven and the amount of time driving.
What is a distance-time graph?If an object moves along a straight line, the distance travelled can be represented by a distance-time graph. In a distance-time graph, the gradient of the line is equal to the speed of the object. The greater the gradient (and the steeper the line) the faster the object is moving.
From the graph, we can see that object A moved 400 km in 5 hours time.
So, in 1 hour the distance travelled by object =400/5=80 km
Therefore, option B is the correct answer.

mile that she
walked. The first day, Ana walked 11 miles.
The second day, she walked 14 miles.
How much money did Ana raise?
Answer:
if $0.25 for each mile, then $1.00 =1 mile.
so the first day would be = $1=1mile
$n=11 miles
= 1n= 11×1=$ 11
Step-by-step explanation:
and the 2nd day is = 14×1= $14.

A central angle of a circle of diameter 6 cm measures 86°. What is the length of the intercepted arc?
A)
2.8 cm
B)
4.5 cm
C)
5.1 cm
D)
9 cm
Answer:
B)
4.5 cm
Step-by-step explanation:
The formula for arc length when our central angle is in degrees =
2πr(θ/360)
θ = 86°
Diameter = 6cm Radius = Diameter /2
Radius = 6cm/2 = 3cm
Hence,
Intercepted arc length = 2 × π × 3 (86/360)
= 2 × π × 3 × 0.2388888889
= 4.5029494701 cm
Approximately = 4.5 cm
Option B is the correct answer

the heights of the peach trees in an orchard are normally distributed with a mean of 12.5 feet and a standard deviation of 1.8 feet.
what is the height of a peach tree with a z-score of -0.5?
Enter your answer rounded to the nearest tenth, in the box.
Answer:
i think 1.8 not sure tho
Answer:
Z-score Formula: z = (x - μ)/σ
Plug in: -0.5 = (x - 12.5)/1.8
Solve: -0.5 * 1.8 = x - 12.5
-0.9 = x - 12.5
-0.9 + 12.5
x = 11.6
Therefore, the height of a peach tree with a z-score of -0.5 is 11.6 feet.
He base rate for a state's workers compensation insurance for a service station attendant is $5.12 per $100.00 paid in wages the payroll for scott park service station for march is 5,784.00. What is the monthly premium for workers compensation insurance?
Answer:
$2961.41
Step-by-step explanation:
Base rate for a state workers compensation insurance = $5,12 per $100 paid in wages
Scott park payroll for march = $5784 ( inclusive of insurance payment )
Determine the monthly premium for insurance
$5.12 = $100
First; calculate how many $100 are in $5784
= 5784 / 100 = 578.4
Hence the monthly premium for workers compensation insurance
= $5.12 * 578.4
= $2961.41
