∑ [tex]\frac{7}{n}[/tex] = 7/1 + 7/2 + 7/3 + 7/4
n=1
Correct choice is A

find the area of the shape below
Answer:
235 cm²
Step-by-step explanation:
Find area of the large rectangle on the bottom. To do that, find its length and width, then multiply them together.
Length of big rectangle=20 cm
Width of big rectangle=9 cm
20x9=180 cm²
Next, find the area of the small rectangle on the top. To do that, find its length and width, then multiply them together.
Length of small rectangle=11 cm
Width of small rectangle=5 cm
I found the width by subtracting 9 from 14, since the 9 cm is part of the large rectangle.
11x5=55 cm²
Add the areas of the two rectangles.
55+180=235 cm²

Find the perimeter of each shape
Equation :
X:
Perimeter:
Answer:
The equation is;
4(2.5x-3) = 3(2x-2)
The value of x is 1.5
Step-by-step explanation:
Mathematically, the perimeter of a square is simply the product of the length of the side and 4
Secondly, the perimeter of an equilateral lateral triangle is the product of the length of its side and 3
Thus, mathematically, we have it that;
4(2.5x-3) = 3(2x-2)
10x - 12 = 6x -6
10x -6x = -6 + 12
4x = 6
x = 6/4
x = 1.5

Kathy dropped a snowball from a building that is 39.2 meters tall. The equation t2 = 39.29.8 represents the amount of time, in seconds, it takes for the snowball to reach the ground. How long did it take the snowball to reach the ground?
Answer:
We note that the equation that is compatible with the given equation is the kinematic equation of free fall where;
t² = 39.2 × 2/9.81
From which we have;
The time it takes the snowball to reach the ground is approximately 2.83 seconds
Step-by-step explanation:
The height of the building from which the ball is dropped, h = 39.2 m
The equation of the dropped a snowball, is given as follows;
t² = 39.2 × 9.8
Using the From the equation of free fall, we have;
s = u·t + 1/2·g·t²
Where;
u = The initial velocity = 0 m/s
t = The time of flight
g = The acceleration due to gravity = 9.81 m/s²
Therefore, we get;
∴ s = The height from which the snowball is dropped = 39.2 m
Therefore, we get;
39.2 = 0×t + 1/2×9.81×t²
∴ t² = 39.2 × 2/9.81 ≈ 7.99
t = √(7.99) ≈ 2.83
The time it takes the snowball to reach the ground, t ≈ 2.83 s.

b) The graph of y = x^2 + 1 is drawn on
the axes on the left.
Use the graph to estimate the
values of x when y = 4.
Give your answers to 1 decimal
place.
Answer:
(-1.7,1.7)
Step-by-step explanation:
OK, first draw the line y=4.
It's a bit misleading- where you think 4 should go is actually 2!
Check the scale and draw down where the two points meet on the line. They should be the same.
You get -1.7 and 1.7

Answer:
The graph on the right is misleading
Step-by-step explanation:
The brand preference is 21 to 25, which shows a slight advantage for Brand B. The graph on the right requires you to mindfully read the y axis to infer that - if you wouldn't, you'd think that Brand B dominates Brand A.

Omealio received a grade of 80 on Exam 1. If his grade in Exam 2 was 15% higher, what was his grade in Exam 2? Please help
Answer:
well if the max grade he could get was 100 then you need to find 15% of 100 which is 15, after that add 15 to 80 and you get 95.
his grade for exam 2 was 95
Step-by-step explanation:
15% of 100 = 15
80 + 15 = 95
Answer:
92
Step-by-step explanation:
15 percent of 80 is 12 percent
80 + 12 = 92

What is the volume of the following rectangular prism?
Answer:
Step-by-step explanation:
It's going to be a mixed number.
Givens
L = 4 units
w*h = 2 1/8 units^2
V=L* (w*h)
V = 4 * (2 1/8)
V = 8 1/2
Where did the 1/2 come from?
You could write 2 1/8 as 2 + 1/8 and use the distributive property.
4(2 + 1/8)
4*2 + 4 * 1/8
8 + 4/8
4/8 = 1/2
8 1/2
Sarah is finding the surface area of a cube. Find the surface area of the cube with dimensions of 8 cm each
Answer:
384 cm^2
Step-by-step explanation:
A = 6a^2 (a = side length)
A = 6(8^2)
A = 6(64)
A = 384 cm^2
More explain stuff:
a^2 is what is used to find the area of a 2 dimensional square. You can also use a · a. Remember, a = side length. Since there are 6 sides/faces in a cube, you multiply the area of each face by 6. :D
For a rectangle with length of
3x + 4 and perimeter of 10x + 18,
what is the width of the
rectangle? Reminder, there are
two lengths and two widths in a
rectangle
Answer:
2x+5
Step-by-step explanation:
Formula for the perimeter of a reactangle= 2(l+b)
So,
2(l+b) = 10x+18
2(3x+4 + b) = 10x+18
Rearrange and solve
3x+4+b = 5x+9
b = 5x+9 - 3x - 4
b = 2x+5
Thus the measurement of the width = 2x+5

You are given m =0.4n - 2/3
What is the value of m, when n is 15?
A.0 3.7
B.4.3
C.6.0
D.8.3
Answer:
m = 5.3
Step-by-step explanation:
Given equation,
→ m = 0.4n - (2/3)
Now we have to,
→ Find the required value of m.
We have to use,
→ n = 15
Then the value of m will be,
→ m = 0.4n - (2/3)
→ m = 0.4(15) - (2/3)
→ m = 6 - (2/3)
→ m = (18/3) - (2/3)
→ m = (18 - 2)/3
→ m = 16/3
→ [ m = 5.3 ]
Hence, the value of m is 5.3.

what is the answer to 4x+7=-2+4x
0=(-9)
Step-by-step explanation:
4x + 7 = -2 + 4x
4x + 7 = 4x -2
subtract 7 from both sides of the equation.
simplify your answer.
subtract 4x from both sides of the equation.
simplify your answer again.
4x + 7 = 4x -2
___-7 = 4x -7
4x __ = 4x -9
__4x = 4x -9
-4x = -4x -9
__0 = -9
the input is a contradiction: it has no solutions.
