Simplified form of expression 125 2/3
Answer:
377/3
Step-by-step explanation:
In general if we have a fraction ( mixed) as ,
[tex]a\dfrac{c}{d}[/tex]
Then the improper fraction will be ,
Improper fraction :-
[tex]\dfrac{ d\times a + c}{d} [/tex]
Using this concept we have ,
→ 125 ⅔
→ 125 × 3 + 2 / 3
→ 375 + 2/3
→ 377/3
Hence the simplified form of the expression is 377/3 .How do I do this? I need answers to 2 decimal places, please. Thanks :)
Step-by-step explanation:
perimeter = 30+(2×25)+(½×3.14×30)
= 30+50+47.1
= 127.1 cm
Area = (25×30)+ (½×3.14×15²)
= 750 + 353.25
= 1.103.25 cm²

Explanation:
Divide the figure so we have a semicircle on the left and a rectangle on the right. The rectangle is 30 by 25. The semicircle has diameter 30.
If we consider a full circle of diameter 30, then its circumference is exactly C = pi*d = pi*30 = 30pi centimeters.
But we only have half a circle, so we cut that in half to get 30pi/2 = 15pi. That's the distance around the curved portion of this diagram. The straight line portions are handled as exactly as you expect.
Add up the distances around the outer edges to get:
15pi+25+30+25 = 15pi+80
The exact perimeter, in terms of pi, is 15pi+80 centimeters.
To get an approximation of this, we can use pi = 3.14 to get
15*pi + 80 = 15*3.14+80 = 127.1 cm
To get a better approximation, use more decimal digits in pi. Or you can let your calculator handle the decimal digits of pi (in other words, use the stored version of it).
The slope of the line that contains the points (2, -7) and (-2, 5) is -3. What is the y-intercept?
A. 11
B. 1
C. -1
D. -13
please help
Answer:
-1
Step-by-step explanation:
You want the y-intercept of the line with slope -3 through point (2, -7).
Y-interceptThe y-intercept can be found by solving the slope-intercept equation for b.
y = mx +b
b = y -mx
For the given point and slope, this is ...
b = -7 -(-3)(2) = -7 +6 = -1
The y-intercept is -1.

Chanelle deposits $7,500 into the bank. She does not withdraw or deposit money for 6 years. She earns 6% interest during that time.
b. what will the balance be when she is finally able to withdrawal her money?
Answer:
10,200 Dollars
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.
Solving our equation:
A = 7500(1 + (0.06 × 6)) = 10200
A = $10,200.00
The following triangular prism has a volume of 10 cubic units and a height of 5 units. The triangular pyramid has a congruent base and the same height, and its longest edge is 7.5 units long. What is the volume of the pyramid?
Answer:
10/3 cubic units (proof below!)
Step-by-step explanation:
The volume of pyramid is, 10/3 cubic units
What is Multiplication?To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Here, We have;
Volume of triangular prism = Base area x Height
= 10
And, Volume of triangular pyramid = 1/3 x Base area x Height
Since, The triangular pyramid has a congruent base and the same height.
Hence, The volume of pyramid = 1/3 x 10
= 10/3 cubic units
Thus, The volume of pyramid is, 10/3 cubic units

Gabriella made her uncle a garden. The width is 9 4/5 ft and the length is 5 3/4 ft. What is the area of the garden?
frations answer
The area of the rectangular garden is (56 + 7/20) ft^2
How to find the area of the garden?
Remember that for a rectangle of length L and width W, the area is:
A = L*W
In this case, we have:
Length = (5 + 3/4)ft
Width = (9 + 4/5)ft
Taking the product we get:
A = (5 + 3/4)ft*(9 + 4/5)ft = 45ft^2 + 4ft^2 + 27/4ft^2 + 12/20 ft^2
= 49ft^2 + 147/20 ft^2
= 49ft^2 + 7ft^2 + 7/20ft^2
= (56 + 7/20) ft^2
The area of the garden is (56 + 7/20) ft^2

375 fish are swimming in a school. First, 47 fish swim away. Then 116 more fish join the school. How many are in the school now? Which operations will you use to find how many fish are in the school now? Are there now more or less than 375 fish in the school? Explain how you know. How many fish are in the school now?
Answer:
444 and yes it is more
Step-by-step explanation:
Given that
There is 375 fish that are swimming in a school
First, 47 fish swim away
Then 116 more fish join the school
We need to find out the number of fish in the school now
So,
= 375 - 47 + 116
= 444
It is more than 375 fish in the school
Basically we deduct the fishes that swim away and add the fishes that join the school
