Which of the following expressions represents the statement “One half the sum of x and y”?
a. 0.5(x=y)
b. 1/2(x+y)
c. x+y/2
The expression 1/2(x + y) is representing one-half the sum of x and y option (b) 1/2(x+y) is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
It is given that:
“One-half the sum of x and y”
Here x and y are the real numbers.
A number is a mathematical entity that can be used to count, measure, or name things. For example, 1, 2, 56, etc. are the numbers.
The sum of the x and y is (x + y)
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
One-half the sum of x and y = 1/2(x + y)
Thus, the expression 1/2(x + y) is representing one-half the sum of x and y option (b) 1/2(x+y) is correct.

A boy wants to jump onto a carousel that is spinning at a rate of 14 revolutions per minute. If the carousel is 23 feet in diamter, how fast must the boy run to match the speed of the carousel and jump on?A) 2.68 feet per second.B) 1,011.59 feet per second.C) 33.72 feet per second.D) 16.86 feet per second.
Answer:
16.86 ft/s
Step-by-step explanation:
Given that
Speed of the carousel, s = 14 rpm
Distance from the carousel, d = 23 ft
To start with, we convert the given speed to revolution per second, so that
s = 14/60 rev/sec
To find the needed speed, we use the formula
v =2πnR, remember that Diameter = 2R, so we substitute D for 2R and get πnD
v = πnD, and we use this to find our needed velocity
v = 3.142 * 14/60 * 23
v = 72.266 * 14/60
v = 16.86 ft/s
Therefore the boy must run at a speed of 16.86 ft/s in order to be able to match the carousel and jump on it

casey wants to buy a gym memebership. One gym has a $80 joining fee and cost $35 per month. Another gym has no joining fee and costs 75$ per month. When would casey pay the same amount to be a member of either gym? how much would she pay?
Answer:
they cost the same after 2 months
Step-by-step explanation:
Since we're looking for these two gyms cost the same, we need to make the equation compare the two together:
35x + 80 = 75x (the 1st gym with a joining fee $80 and 35 monthly equals $75 monthly)
Subtract 35x from both sides:
35x - 35x + 80 = 75x - 35x
80 = 40x
Divide by 40:
80 / 40 = 40x / 40
2 = x
So they cost the same after 2 months
35 * 2 + 80 = 75 * 2
150 = 150
And you'll be spending $150 in total.

Ganesh is making a scale model of the Space Needle in Seattle, Washington. The space needle is 605 feet tall. If the model is 1/100 the actual size of the Space Needle, how tall is the model? _____ feet
Answer:
[tex]Model = 6.05ft[/tex]
Step-by-step explanation:
Given
[tex]Space\ Needle = 605ft[/tex]
[tex]Scale\ Model = \frac{1}{100}[/tex]
Required
Determine the height of the model.
To do this, we simply multiply the scale model by the height of the space needle.
[tex]Model = Scale\ Model * Space\ Needle[/tex]
[tex]Model = \frac{1}{100} * 605ft[/tex]
[tex]Model = \frac{605ft}{100}[/tex]
[tex]Model = 6.05ft[/tex]
Hence, the height of the model is 6.05ft
