The sum of a man and his wife is 81 years. The ratio of their ages is 5:4 Find the age of the younger person
Answer:
Age of a younger person (wife) is [tex]36[/tex] years.
Step-by-step explanation:
The sum of a man and his wife is [tex]81[/tex] years.
Also, ratio of their ages is [tex]5:4[/tex]
Let ages of a man and his wife be [tex]5x[/tex] and [tex]4x[/tex].
Therefore,
[tex]5x+4x=81\\9x=81\\x=9[/tex]
Age of man [tex]=5x=5(9)=45[/tex] years
Age of his wife [tex]=4x=4(9)=36[/tex] years.
So,
age of a younger person (wife) is [tex]36[/tex] years.

Kelly has 236 feet of fence to use to enclose a rectangular space for her dog. She wants the width to be 23 feet. Select the correctly labeled rectangle that could be the space for Kelly's dog.
Answer:
Length = x feet = 95 feet
Step-by-step explanation:
The labeled triangles are not included in the question, therefore, I will calculate the length of the rectangular space for Kelly's dog
Perimeter of a rectangle = 2(length + width)
Perimeter of a rectangle = 236 feet
Width = 23 feet
Length = x feet
Perimeter of a rectangle = 2(length + width)
236 = 2(x + 23)
236 = 2x + 46
236 - 46 = 2x
190 = 2x
x = 190/2
x = 95 feet
Length = x feet = 95 feet

Manuel wants to build a model of Captain America's famous shield out of cardboard. The outer ring of the shield is colored red. The next ring is white. The third ring is also red. The center is blue with a white star. The radius of the whole shield is 14 inches. However, Manuel just wants to know the area of the space he needs to paint red. Use 3.14 for Pi. Round to the nearest hundredth
Answer:
615.44 in²
Step-by-step explanation:
The shape of Captain America's shield = Circular
The area of a circle = πr²
The radius of the whole shield = 14 inches.
The first ring = Red ring
Hence, the area of the red ring =
π = 3.14
3.14 × 14²
= 615.44 in²
The area of the space he needs to paint red is 615.44 in²

Give the equation for the new circle obtained by translating the circle (x+2)^2 + (y-1)^2 = 25 by 3 units to the right and 2 units down
Answer:
(x - 1)^2 + (y + 1)^2 = 25
Step-by-step explanation:
The equation of a circle centered in the point (a, b) with a radius R is:
(x - a)^2 + (y - b)^2 = R^2
If we translate the circle 3 units to the right and 2 units down, then we translate the center 3 units to the right and 2 units down.
So if the original center was (a, b), and we translate it 3 units to the right, then we need to add 3 to the x-component, we get:
(a + 3, b)
Now if we want to move the center two units down, we need to subtract 2 in the y-value, we get:
(a + 3, b - 2)
This will be the new center of the circle.
Now let's look at our circle, we have:
(x + 2)^2 + (y - 1)^2 = 25
The center of this circle is:
(-2, 1)
After the translation, the center will be:
(-2 + 3, 1 - 2)
(1, -1)
Then the equation for the translated circle is:
(x - 1)^2 + (y - (- 1))^2 = 25
(x - 1)^2 + (y + 1)^2 = 25
What is the circumference of a circle when the diameter of the circle is 10 units?

there are 14 red marbles and 19 blue marbles in a bag you randomly choose one of the marbles what is the probability of choosing a red marble write your answer as a fraction in simplest form
Answer:
4/23
Step-by-step explanation:
Probability of choosing a red marble = # of red marbles / total # of marbles
We are told that there are 4 red marbles and 19 blue marbles
So the # of red marbles = 4
And the total # of marbles = 4 + 19
4 + 19 = 23
So there are a total of 23 marbles
Recall that probability of choosing a red marble is equal to # of red marbles / total # of marbles
Hence, the probability of choosing a red marble is 4/23
Note: 4/23 is already in it's simplest form so no simplifying has to be done.
Answer:
14/33
Step-by-step explanation:
There are 14 red marbles and 19 blue marbles, meaning that there are 33 marbles in all:
14 + 19 = 33
You are randomly choosing a red marble out of the total amount of marbles. 14/33
Note that you cannot simplify the fraction anymore, and so 14/33 is your answer.

Step-by-step explanation:Definition of square and rectangle
A plane figure having four equal sides and four right (90°) angles in geometry is called a square.
A rectangle is a two-dimensional shape with four sides, four corners, and four right angles. A rectangle's opposite sides are the same length, with one pair being longer than the other.
The area of given square= a²
The area of rectangle= 2*4
Hence the area of shaded region= [tex]a^{2} -(2*4)[/tex]

Step-by-step explanation:
8. Slope-intercept form is ...
y = mx + b . . . . . . . where m is the slope, and b is the y-intercept
You will notice that y is by itself on the left side of the equation, and that there are two terms: an x-term and a constant.
The first two equations are NOT in slope-intercept form.
The last two equations ARE in slope-intercept form.

Jill counted 105 people in front of her in line for a park train ride. The train holds 12 people on each trip. How many trips will the train take before it is jill turn?
Answer:
105 divide 12 = 8.75 so therefore, there will be 8 trips before it is jill's turn
Answer:
8 trips
Step-by-step explanation:
Divide 105 by 12 to find how many trips the train will take:
105/12
= 8.75
This means that the train will take 8 trips before it is Jill's turn. Since you can only have a whole number of trips, we have to round 8.75 down to 8.
So, the train will take 8 trips before it is Jill's turn.
Find the value of x and show all steps please
Answer:
x = 88
Step-by-step explanation:
Opposite angles in a quadrilateral inscribed in a circle are supplementary
Supplementary meaning that the sum of the two angle measures is 180
The opposite angle of "x" is ∠B which has a measure of 92°
Thus, 92 + x = 180
180 - 92 = 88
Hence, x = 88
