Answer:
28
Step-by-step explanation:
the ratio of their ages is 9 : 7 = 9x : 7x ( x is a multiplier ) , then
9x = 7x + 8 ( Jameelah is 8 years older than Anna )
Subtract 7x from both sides
2x = 8 ( divide both sides by 2 )
x = 4 , then
7x = 7 × 4 = 28
That is Anna is 28
Answer:
28
Step-by-step explanation:
Let us take , age of Anna be x , then the age of Jameelah = x + 8 . Also the ratio of ages is 9:7 . So ,
According to the Question :-
[tex]:\implies[/tex] x + 8/x = 9/7
[tex]:\implies[/tex] 7( x + 8) = 9x
[tex]:\implies[/tex] 7x + 56 = 9x
[tex]:\implies[/tex] 9x - 7x = 56
[tex]:\implies[/tex] 2x = 56
[tex]:\implies[/tex] x = 28
Hence the age of Anna is 28 years .im giving brainlist away.......

No - Range is Max - Min = 6-0 = 6
The range is 6
Answer:
No, Madison did not find the range correctly.
Step-by-step explanation:
To find the range of any data set, take the smallest and the largest numbers and subtract them. The largest number in this data set is 6 and the smallest is 0, so
6 - 0 = 6
the range is 6.

Reuben L. Goldberg and His Machines
The Artist and His Work
Reuben (Rube) L. Goldberg was an American cartoonist. He is best known for drawing elaborate machines. His drawings showed machines with wheels, gears, handles, pails, and other interesting devices. The machines in Goldberg's drawings were designed to take a simple task and make it complex. The contraptions he drew 80 years ago were so funny that they continue to inspire young scientists and engineers today.
Goldberg's Career
Goldberg's cartoons appeared in several respected New York City newspapers, including the New York Evening Journal and the New York Evening Mail. The cartoonist also wrote a feature film called Soup to Nuts, which was the first film starring the Three Stooges. Goldberg's machines appear in the film.
How to Build a Cause-Effect Machine
Every year students build machines based on Goldberg's designs for school projects, for competitions, or simply for fun. Goldberg's machines operate based on cause and effect. Students and engineers of all ages can learn to build these elaborate cause-effect machines. The key to building one of these machines is to understand how to use gravity and force to push and pull objects along a path. Reading up on these concepts is a good place to start. After that, building the machines is all about having fun. Find a simple task for the machine to do. Then, find a complicated way for the machine to do it.
The Cause-Effect Machine in Popular Culture
Cause-effect machines are incredibly fun to watch. For this reason, they have found their way into Hollywood movies such as Back to the Future and The Goonies. The machines also inspired a board game for kids called Mouse Trap. Clearly, Goldberg's machines have a place in our popular culture.

4/5 minus 1/3 plz i need help
Answer:
7/15
Step-by-step explanation:
Step 1
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 4 by 3, and get 12.
Then we multiply 1 by 5, and get 5.
Next we give both terms new denominators -- 5 × 3 = 15.
So now our fractions look like this:
12
15
−
5
15
Step 2
Since our denominators match, we can subtract the numerators.
12 − 5 = 7
So the answer is:
7
15
Step 3
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?
To find out, we try dividing it by 2...
Nope! So now we try the next greatest prime number, 3...
Nope! So now we try the next greatest prime number, 5...
Nope! So now we try the next greatest prime number, 7...
Nope! So now we try the next greatest prime number, 11...
No good. 11 is larger than 7. So we're done reducing.

Brody sliced a small pizza into 12 equal pieces. He ate ~ of the pizza. Which model represents three-fourths of twelve?
Answer:
Pie chart.
9 slices
Step-by-step explanation:
Three-fourths of twelve is written as
3/4 * 12
i.e 3/4 is multiplied by 12
multiplying 3 by 12 gives 36 and dividing it by 4 gives 9 .
So Brody ate 9 slices out of the 12 slices of pizza.
The graph used in circular shape is called the a pie chart.
If we draw a pie chart 3 of the 4 sections will be colored showing that he ate 3/4 of the pizza representing 9 slices out of 12.
Each slice can be represented separately.

The function represents the cost in dollars of playing a video game in terms of time spent playing in months.
y = 15x +45
What can you interpret from this function?
It costs $15 a month to play the video game.
There is an initial cost of $45 to play the video game.
There is an initial cost of $15 to play the video game.
It costs $45 a month to play the video game.
The y-variable represents the cost in dollars, and the x-variable represents the number of months.
The y-variable represents the number of months, and the x-variable represents the cost in dollars.
Answer:
It costs $15 a month to play the video game.
The initial cost is $45.
The y-variable represents the cost in dollars.
The x-variable represents the number of months.
Step-by-step explanation:
If you break the function down, you're going to have:
Total = Monthly Cost + Initial Cost
In this case, 15x is your monthly cost, as you can think of x as the number of months meaning:
15 for the first month (x = 1)30 for the second month (x = 2)45 for the third month (x = 3), and so onOur initial cost is always going to be a set amount, thus our constant, $45.
This leaves y as our total, which makes sense, as it's all alone on one side of the equation, where as all the costs are bunched together on the right side.
Hope this helps!

The graph shows the distance, y, in miles, of an eagle from its nest over a certain amount of time, x, in minutes.
Graph titled Distance Vs Time is shown with Time in minutes along the x-axis and Distance from Nest in miles along the y-axis. The scale on the x-axis shows the numbers 0 to 40 at increments of 8, and the scale on the y-axis shows the numbers 0 to 32 at increments of 4. A straight line joins the ordered pairs 0, 16 and 8, 20 and 16, 24 and 24, 28 and 32, 32.
Based on the graph, what is the initial value of the graph and what does it represent?
A) 16 miles per minute; it represents the speed of the eagle
B) 0.5 mile per minute; it represents the speed of the eagle
C) 0.5 mile; it represents the original distance of the eagle from its nest
D) 16 miles; it represents the original distance of the eagle from its nest

Sharon has 23 toy car that are colored red, blue, and white. She has 4 red cars, 2 fewer blue cars than red and 5 more purple how many white cars does sharon have?
Answer:
13 white cars
Step-by-step explanation:
Let us represent:
Number of
Red cars = x
Blue cars = y
White cars = z
Sharon has 23 toy car that are colored red, blue, and white.
x + y + z = 23
x = 4
2 fewer blue cars than red
y - 2 = x
y - 2 = 4
y = 4 + 2
y = 6
Hence,
x + y + z = 23
4 +
Number of white cars is calculated as:
23 - (6 + 4)
23 - 10
= 13 white cars
25% of x = 75 what is x?
Answer:
x = 300
Step-by-step explanation:
25% of x = 75
(25x/100) = 75
25x = 7500
x = (7500/25)
x = 300
Thenks and mark me brainliest :))
Answer:
x = 300
Step-by-step explanation:
Let's solve your equation step-by-step.
25100x=75
Step 1: Simplify both sides of the equation.
14x=75
Step 2: Multiply both sides by 4.
4*(14x)=(4)*(75)

The diameter below shows a circle placed inside a square. The square has an area of 132.25 ft 2. What is the approximate area of the circle?
Answer:
104ft^2
Step-by-step explanation:
Area of a square = L²
L is the side length of the square
132.25 ft² = L²
L = √132.25
L = 11.5ft
This shoes that the diameter of the circle is 11.5ft
Area of a circle = πd²/4
Area of a circle = 3.14(11.5)²/4
Area of a circle = 3.14(132.25)/4
Area of a circle = 103.82
Hence the approximate area of the circle is 104ft^2
