Answer:
157 cm^2
Step-by-step explanation:
1) find the radius
radius = side of the square /2 = 10 /2 = 5 cm
2) notice that four semicircles are equals to two circles
3) find the area of the shaded region
A = radius^2 x pi x 2 = 5^2 x pi x 2 = 157 cm^2 (round the nearest whole number)
in a company, 60% of workers are women. if 800 people work on the company who aren't women, how many workers are there in all? use pencil and paper. show two different ways that you can solve this problem. how many workers in all?
Answer:
2000 workers
Step-by-step explanation:
All the workers: 100%
Women: 60%
Others: 40% = 800 workers
=> 1% of the workers: 800/40 = 20 workers
=> 100% = 20 x 100 = 2000 workers

F(x)=2x^3+2x-3 g(x)=-.5[x-4] what is the y value when f(x) = g(x)?
Answer:
D. x = 0.5
Step-by-step explanation:
A graphing calculator is the quickest way to get to an answer here.
f(x) = g(x) for x = 0.5
__
We can find the y-intercepts of the two functions to be ...
f(0) = -3
g(0) = -2
We know the x-intercept of g(x) is x=4. The x-intercept of f(x) will be a value less than 1, because f(1) = 1. (The function crosses the x-axis between x=0 where f(x) < 0 and x=1, where f(x) > 0.)
Considering these intercept points, we know the value of x for f(x)=g(x) will be between x=0 and x=1. There is only one answer choice in that interval:
x = 0.5

This is a simple cross multiplication problem! Any time you're given a ratio and then the actual quantity of something, you can use cross multiplication to figure out the quantity of the other thing!
We know that the ratio of toads to frogmen is 7 : 2. We also know there were 98 actual toads. Therefore we can set up our equations!
[tex]ratio_{toads}=ratio_{frogmen}\\actual_{toads}=actual_{frogmen}\\\\7=2\\98 = x\\\\7x=196\\x=28[/tex]
The first two equations above everything is how you would have everything set up! The second equations under them are the numbers plugged in, and the rest is just simplification.
So, your final answer should be 28 frogmen!
27. If A=7-4w + 5v + 10wv and B = 7w + 3wv-12, find A + B, A-B and B-A.
Answer:
A+B = 7-4w+5v +10wv + 7w +3wv - 12
=3w +5v +13wv-5
A-B= 7 - 4w +5v +10wv - (7w +3wv - 12)
=7 - 4w +5v +10wv - 7w - 3wv + 12
=19 - 11w +5v +7wv
B-A =7w +3wv - 12-(7 - 4w +5v +10wv)
=7w +3wv - 12 - 7 + 4w - 5v - 10wv
=11w - 7wv - 19 - 5v
For what values of k are the graphs of 8y=4x+3 and 4y=k(x+5) parallel? perpendicular?
parallel k= __
perpendicular k= __
The values of k for parallel and perpendicular in the equations 8y=4x+3 and 4y=k(x+5) are 7/12 and 1/21, respectively.
what is slope ?A line's slope determines how steep it is. A mathematical expression for the gradient is called "gradient overflow" (the change in y divided by the change in x). The slope is the ratio of the vertical change (rise) between two points to the horizontal change (run) between those same two points. When a straight line's equation is written as y = mx + b, the slope-intercept form of an equation is used to represent it. The y-intercept is located at a point where the line's slope is m, b is b, and (0, b). For instance, the slope of the equation y = 3x - 7 and the y-intercept (0, 7).
given
for parallel their slope will be equal
y1= 1x/2 + 3/8 .... eq1
y2= kx/4 + 5k/4 ..... eq2
y1 = y2
1x/2 + 3/8 = kx/4 + 5k/4
1/2 + 3/8 = k/4 + 5k/4
7/8 = 6k/4
k = 7/12
for perpendicular product of their slope is 1
y1 * y2 = 1
1x/2 + 3/8 * kx/4 + 5k/4 = 1
1/2 + 3/8 * k/4 + 5k/4 = 1
k = 1/21
so The values of k for parallel and perpendicular in the equations 8y=4x+3 and 4y=k(x+5) are 7/12 and 1/21, respectively.

3. At practice the team wants to know how fast Ryan can skate. He skates 10 laps around the
rink in 3 minutes and, later on in practice he skates 5 laps in 1 minute. What was his
average speed in laps per minute?
The average speed in laps per minute of Ryan is 2.5 laps per minute
How to determine the average speed in laps per minute?From the question, we have the following parameters that can be used in our computation:
He skates 10 laps around the rink in 3 minutes In practice he skates 5 laps in 1 minuteThe above can be expressed as
(x, y) = (1, 5) and (3, 10)
The average speed in laps per minute can be calculated using the following slope equation
Slope = (y₂ - y₁)/(x₂ - x₁)
Rewrite as
Average speed = (y₂ - y₁)/(x₂ - x₁)
Where
(x, y) = (1, 5) and (3, 10)
Substitute the known values in the above equation
So, we have the following equation
Average speed = (10 - 5)/(3 - 1)
Evaluate
Average speed = 2.5
Hence, the average speed is 2.5

Answer:
A. 69°
Step-by-step explanation:
Given:
m<FED = 179°
m<NED = 19x - 4
m<FEN = 12x - 3
Required:
m<FEN
Solution:
m<NED + m<FEN = m<FED (angle addition postulate)
19x - 4 + 12x - 3 = 179 (substitution)
Add like terms
31x - 7 = 179
31x - 7 + 7 = 179 + 7
31x = 186
31x/31 = 186/31
x = 6
✔️m<FEN = 12x - 3
Plug in the value of x
m<FEN = 12(6) - 3 = 72 - 3
m<FEN = 69°

Answer:
Domain is all real numbers (basically any number)
Step-by-step explanation:
Step 1: Simplify the expression first
y = 2(x+1)-(3x-2)
y = 2x + 2 -3x + 2
y = -x + 4
Step 2: Observe the graph
y = -x + 4 is simply a linear graph with a negative fixed gradient of -1, with a y-intercept of 4.
Step 3: Identify the domain
For linear graphs, domain is all real numbers.

An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 24 inches, and the length of the base is 11 inches. Find the triangle's perimeter. Round to the nearest tenth of an inch.
Answer: 60.2 inches
The perimeter of the triangle is 80.24 inches.
What is Pythagoras theorem?The relationship between the three sides of a right-angled triangle is explained by the Pythagoras theorem, commonly known as the Pythagorean theorem. The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.
Given:
Altitude = 24 inches
Base = 11 inches
Half of the base = 11/2 = 5.5 inches
Using Pythagoras theorem:
Hypotenuse = √(24² + 5.5²)
Hypotenuse = √(576+ 30.25)
= √606.25
= 34.62 inches
Now, perimeter of a triangle
= (base + side 1 + side 2)
= (11 + 34.62+ 34.62)
= 80.24 inches
Hence, the perimeter of the triangle is 80.24 inches.
