Calculate the area of this figure. Show all work and include proper units.
Check photo for units
Answer:
92 ft²Step-by-step explanation:
If you complete the square, you will add a right triangle with legs 10 - 6 = 4 ft.
The area of the figure is:
A = 10² - 1/2*4*4 = 100 - 8 = 92 ft²plz help find the ration of the areas of the squares pqrs to that of abcd where pq=9cm and ab=5cm
Answer:
81 : 25
Step-by-step explanation:
Area of square ABCD = side * side = 5 * 5 = 25 cm²
Area of square PQRS = 9 * 9 = 81 cm²
Ratio of square PQRS to square ABCD = 81 : 25
This cannot be reduced, as there are no common factors
A bag has 4 red marbles, 5 blue marbles, and 6 green marbles. What is the probability if choosing a red marble from the bag, not putting it back, and then choosing a green marble?
Answer: 4/35
Step-by-step explanation:
Number of red marbles = 4
Number of blue marbles = 5
Number of green marbles = 6
Total number of marbles = 4+5+6 = 15
When a red marble is picked, the probability is 4/15, then to pick a green marble after that, we have 14 marbles left and probability of picking green is 6/14.
Now, probability of choosing a red marble from the bag, not putting it back, and then choosing a green marble will be:
= 4/15 × 6/14
= 24/210
= 4/35

If the given lengths of a triangle are 16 and 10 which can NOT be the third side?
A.21
B.22
C.25
D.27
Answer:
D.27Step-by-step explanation:
This is because,
According to Triangle Inequality Property:
Measurement of any two sides of a triangle is always greater than the third side.
Here,
10 + 16 = 26 > 21
10 + 16 = 26 > 22
10 + 16 = 26 > 22
But,
10 + 16 = 26 < 27
Hence,
Option D: 27 can't be the measurement of the triangle.
a baseball team played 32 games and lost 8 . Katy was the catcher in 5/8 of the winning games and 1/4 of the losing games. what fraction of the games did the team win? and how many games did Katy play catcher
Answer:
17
Step-by-step explanation:
what you have to is simple, first do 32-8 which get you 24, thats how many they won. Then do 8x1/4 to get 2, she played 2 games as catcher and lost, then do the same thing with the winning games. 24x5/8 should get you 15. she played 15 games as catcher and won. then do 15+2 to get 17.
hope that helps!
Answer:
1/4 - won

The length of a rectangle is 1 m less than twice the width, and the area of the rectangle is 21 m?. Find the dimensions of the rectangle.
Answer:
length = 6
width = 3 1/2
Step-by-step explanation:
l = length
w = width
l = 2w-1
w(2w-1) = 21
2w² - 1 - 21 = 0
(2w - 7)(w + 3) = 0
w = 7/2 = 3 1/2
find 'l': l = 2(7/2) - 1 = 7-1 = 6
If the perimeter of a square is 80, which is the area?
The roots of the equation x^2+bx+x=0 are -4 and 2.
Find B and C
Answer:
b = 2, c = - 8
Step-by-step explanation:
Given x = a is a root then (x - a) is a factor
Here the roots are x = - 4 and x = 2 , then the corresponding factors are
(x + 4) and (x - 2)
The equation is then the product of the factors , that is
(x + 4)(x - 2) = 0 ← expand factors using FOIL
x² + 2x - 8 = 0
with b = 2 and c = - 8

Answer:
5x² - 5x + 17
Step-by-step explanation:
(3x² + 7) + (2x² - 5x + 10)
Combine the like terms.
3x² + 2x² = 5x²
-5x does not have a like term, so there is no change.
7 + 10 = 17
Combine them, and the final equation is
5x² - 5x + 17.
Answer: 5x² - 5x + 17

The required quadratic function shown in the graph is
f(x)=0.5(x+2)(x-6).
Let us suppose the quadratic function
[tex]f(x)=a(x-\alpha )(x-\beta )[/tex]......(1)
where α and β are roots of the quadratic equation f(x)=0
What is a quadratic equation?Any equation of the form [tex]ax^{2} +bx+c=0[/tex] is called a quadratic equation where a≠0
From the shown graph we can see the roots of f(x)=0 as:
[tex]\alpha =-2[/tex]
[tex]\beta =6[/tex]
So, (1) becomes [tex]f(x)=a(x+2 )(x-6 )[/tex].....(2)
Since the graph is intersecting the y-axis at (0, -6)
So, (0, -6) will satisfy the (2)
So put x=0 and f(x)= -6 in (2)
[tex]-6=a(0-2)(0-6)[/tex]
[tex]a=\frac{-1}{2}=0.5[/tex]
So, [tex]f(x)=0.5(x+2 )(x-6 )[/tex]
Thus, the required quadratic function shown in the graph is
f(x)=0.5(x+2)(x-6).

Answer:
the area of the circle is 4π
Step-by-step explanation:
The computation of the area of the circle is shown below:
As we know that
The area of the circle = πr^2
where
diameter = 4
So radius = diameter ÷ 2
= 4 ÷ 2
= 2
Now the area of the circle is
= π × 2^2
= 4π
hence, the area of the circle is 4π

E(x) = 3.15.
What is distribution in probability?By displaying the proportion of data points (referred to as "bars") that fall inside a certain range of values, a histogram gives a visual explanation of numerical data. A vertical bar graph and a histogram are comparable.
E(X) = ∑( x ∗ P(x))
Given a probability histogram for a discrete random variable X.
We will drive the P(x) for every value of x.
P(X=1)=0.1
P(X=2)=0.2
P(X=3)=0.3
P(X=4)=0.25
P(X=5)=0.15
Putting these values in a summation equation to find E(x)
E(x) = 1*0.1 +2*0.2 + 3*0.3 + 4*0.25 + 5* 0.15
E(x) = 3.15
Therefore E(x) for the given histogram far random variable x will be 3.15.
