Answer:
We can't find an exact number, but the answer is x.
Hey there :)
The given are 104, 137, 154, 131 and we have to find x
The mean value is 130
Mean = sum of all values divided by total number of values
130 =
130 x 5 = 526 + x
650 = 526 + x
124 = xYour answer will be option
A) 124
You have a rectangle that is 8 ft by 10 ft
Area = 8 * 10 = 80 square feet.
Then there is a triangle 8 ft high with a base of 4 feet.
Area = /2 x 8 x 4 = 16 square feet.
Add together for total area:
80 + 16 = 96 square feet.
Answer:
y=3
Step-by-step explanation:
Assuming this is an enlargement where EFGH is enlarged to ABCD then the former is the object and the latter is the image. If so then
scale factor(k) of the enlargement=image length/corresponding object length
k=3/2
Therefore, y=4.5/k
y=4.5/(3/2)
y=3
If we take the assumption another way and say ABCD is reduced to EFGH then the former is the object and the latter is the image.
In that case,
k=⅔
y=4.5×k
y=3
In either case y=3units
First add 10 to both sides:
3x-10=11+10
3x=21
Divide three by both sides to get x by itself:
3x/3=21/3
x=7
