Step-by-step explanation:
The teacher should not need to spend any time teaching this. The area of the total figure is the sum of the areas of its parts. You already know that. And, you already know how to compute the areas of triangles and rectangles.
__
You may recall that the area of a triangle is ...
A = 1/2bh
and the area of a rectangle with the same base and height is ...
A = bh
So, a triangle with base b and height h has the same area as a rectangle with the same base (b) and half the height (h/2). Recognizing this makes these problems really simple.
__
23. The base of the rectangle and triangle is 7 m. The height of the triangle is 4 m, so its area is equivalent to adding 4/2 = 2 m to the 4 m height of the rectangle. Then the total area is ...
A = (7 m)(4 m +(1/2)(4 m)) = (7 m)(6 m) = 42 m^2
__
24. Since there are two identical triangles of height 5, their total area is equal to that of a rectangle of height 5.
A = (12 ft)(7 ft +5 ft) = 144 ft^2
__
25. The 5 cm height of the triangle makes it have an area equivalent to a rectangle 5/2 cm high.
A = (8 cm)(6 cm +5/2 cm) = 68 cm^2
Note: we have read the fuzzy numbers as 8 cm wide, 6 cm high for the rectangle, and 5 cm high for the triangle. If your figure is different, please use the appropriate numbers in the calculation.

Order 5/8 , 0.5 , 58.3% greatest to least
Answer:
0.5,5/8, 58.3
Step-by-step explanation:
0.5 is 1/2, and 5/8 is 1/8th larger than 1 half, and 58.3 is the only one with a whole number, so its the largest. Hope this helped, can i maybe get brainliest :D
The required ascending order is given as 0.5, 58.3%, and 5/8.
Given that,
To arrange the given number in ascending order,
5/8 , 0.5 , 58.3%
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
5 / 8 = 0.625
58.3% = 0.583
So,
0.5 < 58.3% < 5/8
Thus,the required ascending order is given as 0.5, 58.3%, and 5/8.

Which of the following is equivalent to 125%
7\4
0.125
5/4
1.025
[tex]\huge\boxed{\boxed{\bold{\frac{5}{4}}}}[/tex]
[tex]\hrulefill[/tex]
Let's start by finding [tex]125\%[/tex] in decimal form. To do this, just divide the percentage by [tex]100[/tex]:
[tex]125\div100=1.25[/tex]
This doesn't match any of our choices, so we'll try fraction form.
A percentage in fraction form is just the percentage over a denominator of [tex]100[/tex].
[tex]\frac{125}{100}[/tex]
Now we divide both the numerator and denominator by their greatest common factor, which is [tex]25[/tex]:
[tex]\frac{125\div25}{100\div25}=\large\boxed{\frac{5}{4}}[/tex]

SOMEONE PLEASE HELP!!!
Answer:
formula: M (x1 +x2/2 , y1+y2/2 )
M(-6+0/2 , -1+1/2)
M(-6/2 , 0/2)
M=(-3,0)
Step-by-step explanation:
The midpoint of the line ST lies on the x-axis with the coordinate, (-3, 0)
What is a midpoint?A midpoint is the center of two points, It lies at the same distance from the two endpoints.
The coordinates of the endpoints of a line ST are as follows:
The coordinate of S is (-6, -1)
The coordinate of T is ( 0, 1)
The midpoint of the line ST is M
The coordinates of M is given as,
M = ( x₁ + x₂) /2 , ( y₁ + y₂) /2
x₁ = -6
x₂ = 0
y₁ = -1
y₂ = 1
The coordinates of M is,
( -6 +0) / 2 , ( -1 +1) /2
-3, 0
The coordinates of the midpoint of the line are ( -3, 0).

At the aquarium there are 840 sharks and 630 lion fish, for a total of 1470 fish all together. What is the ratio of fish to sharks?
(Reduce your ratio to lowest terms, for example reduce 15:6 to 5:2
Answer:
7:4
Step-by-step explanation:
The number of sharks at the aquarium is 840
The number of lion fish is 630
The total number of fish is 1470
Therefore the ratio of fish to sharks can be calculated as follows
= 1470/840
= 7:4
Hence the ratio of fish to sharks is 7:4

Hannah took six quizzes in math. She scored 4 twice, 6 once, and 8 three times. What ja Hannah’s average for the six math quizzes?
Answer:
Option H. 6⅓
Step-by-step explanation:
Let X be the score.
Let F be the number of scores (i.e the frequency)
From the question given above, the following data were obtained from:
X >>>>>>>>> F
4 >>>>>>>>> 2
6 >>>>>>>>> 1
8 >>>>>>>>> 3
Thus, we can obtain the average as follow:
X >>>>>>>>> F >>>>>>> FX
4 >>>>>>>>> 2 >>>>>>> 8
6 >>>>>>>>> 1 >>>>>>> 6
8 >>>>>>>>> 3 >>>>>>> 24
Summation (FX) = 8 + 6 + 24
Summation (FX) = 38
Summation (F) = 2 + 1 + 3 = 6
The average = summation (FX) /Summation F
The average = 38/6
The average = 6⅓
Therefore, Hannah's average for the six math quizzes is 6⅓.
