Answer:
3.26
Step-by-step explanation:
33.5/3.14 = 10.66 ( when rounded to the nearest tenth).
10.66 square rooted is 3.26
The required radius of the sphere is 2 inch.
Volume of sphere = 33.5 cubic inches . Radius of sphere to be determine.
Volume, is defined as mass gained per unit cube of density.
Here, area of sphere = [tex]4/3\pi r^3[/tex]
33.5 = 4/3 πr³
r³ = 33.5 * 3/4π
r = 2
Thus, the required radius of the sphere is 2 inch.

The following three shapes are based only on squares, semicircles, and quarter circles. Find the perimeter and the area of each shaded part.
Answer:
Step-by-step explanation:
The total shaded area = area of the square - area of a circle
= 9^2 - π * 4.5^2
= 17.3827
The 2 shaded parts both have area 8.69 unit^2 ( to nearest hundred)
Perimeter:
The perimeter of the top shaded part
= AB + 1/2 circmference of the circle
= 9 + 1/2 * 2 π r
= 9 + 14.137
= 23.14 units ( to nearest hundredth)
The bottom part has the same perimeter.
Answer:
area: 17.38 cm²perimeter: 46.27 cmStep-by-step explanation:
You want the perimeter and area of the part of a 9 cm square remaining after a semicircle is removed from two opposite sides.
AreaThe shaded area is the area of the 9 cm square less the area of a 9 cm circle. That area is ...
A = s² - π(s/2)² = s²(1 -π/4) . . . . . where s is the side length of the square
A = (9 cm)²(1 -π/4) ≈ 17.38 cm²
The area is about 17.38 cm².
PerimeterThe perimeter is the circumference of the circle plus two sides of the square.
P = C +2s
P = πs +2s = s(π+2)
P = (9 cm)(π+2) ≈ 46.27 cm
The perimeter is about 46.27 cm.

Max went to a shopping mall with $35 in his wallet. He spent two fifths of the money he had in his wallet at the bookstore. How much money, in dollars, did he have left?
$21
$26
$10
$13
Answer:
$21
Step-by-step explanation:
1) Find the amount spent.
"Two fifths" = 2/5
So, he spent 2/5 of 35.
= 2 x 35 / 5
= 70 / 5
= 14
2) Subtract 14 from 35, since 35 is the total amount of money he had.
= 35 - 14
= 21
Answer:
$21
Step-by-step explanation:
Given that:
Max went to a shopping mall with $35 in his wallet.
He spent two fifths of the money he had in his wallet at the bookstore.
To Find:
How much money, in dollars, did he have left?
Solution:
Let the left money that max have = x
Base on the given:
$35-(2/5)×$35=x
⇒ $35-($2×7)=x
⇒ $35-$14=x
⇒ x=$21
Hence, max has $21 left.

The second term of an arithmetic sequence is –39. The rule a, - a-1 +12 can be used to find the next term of the
sequence. What is the explicit rule for the arithmetic sequence?
Answer:
a 2 = -39
a 2 = a 1 + 12
- 39 = a 1 + 12
a 1 = - 39 - 12
a 1 = - 51 ( first term )
The common difference is : d = 12
The explicit rule for the arithmetic sequence:
a n = a1 + ( n - 1 ) d
a n = -51 + ( n - 1 ) · 12

The correct statement about the data collected by Ms. Pearson is that there is no association between a student's absences and the final average grades.
When do variables have a linear relationship?The equation that represents a linear relationship is: a + bx
Where x represents the rate of increase. Thus, for linear equations, the functiion increases by a constant term.
Looking at the table, the average final grade does not increase by a constant term.

Answer:
95 in²
Step-by-step explanation:
The total area of a pyramid is the sum of the areas of the triangular faces and the area of the base.
__
face areaHere, each triangular face has a base of 5 in, and a slant height of 7 in. Its area will be given by the area formula for a triangle:
A = 1/2bh
A = 1/2(5 in)(7 in) = 35/2 in² . . . . area of one of four congruent faces
__
base areaThe area of the base is that of a square with 5-inch sides. It is given by the formula ...
A = s²
A = (5 in)² = 25 in²
__
total areaThen the total surface area is .
area of base + 4 × triangle area
= 25 in² + 4(35/2 in²) = 95 in² . . . . . surface area of the pyramid

Pythagorean Theorem (Rounding)
Answer:
13.4 :)
Step-by-step explanation:
Pythagorean theorem: a^2 + b^2 = c^2
Now lets solve!!
12^2 + b^2 = 18^2
144 + b^2 = 324
Now we subtract!!
324 - 144 = b^2
180 = b^2
Now we need to find the square root!!
