Answer:
Number of cup used for fill bowl = 20 cups (Approx.)
Step-by-step explanation:
Given:
Diameter of hemisphere bowl = 10 inches
Volume of each cup = 12.5 cubic inches
Find:
Number of cup used for fill bowl
Computation:
Radius of hemisphere bowl = Diameter of hemisphere bowl / 2
Radius of hemisphere bowl = 10 / 2
Radius of hemisphere bowl = 5 inches
Volume of hemisphere bowl = (2/3)(π)(r³)
Volume of hemisphere bowl = (2/3)(22/7)(5³)
Volume of hemisphere bowl = (2)(125)
Volume of hemisphere bowl = 250
Number of cup used for fill bowl = Volume of hemisphere bowl / Volume of each cup
Number of cup used for fill bowl = 250 / 12.5
Number of cup used for fill bowl = 20 cups (Approx.)
Ben orders a cost of us tovorite macaroni and cheese. The case contains 18 same-
size boxes that weight a totçi of 7.2 pounds. Which set of equations represents the weight in
pounds, of each box bí mocaroni and cheese, z?

Which polynomial function has zeros at -3, 0, and 4?
f(x) = (x + 3)(x2 + 4)
f(x) = (x2 - 3)(x - 4)
f(x) = x(x + 3)(x - 4)
f(x) = x(x - 3)(x + 4)
Answer:
If 5 is zero then (x - 5) is a factor.
Only 4. has this factor.

How do you Write a problem in Standard Form?
Answer:
Standard form is a way of writing down very large or very small numbers easily. 103 = 1000, so 4 × 103 = 4000
Step-by-step explanation:
First, Switch sides,
y-y^1=m\left(x-x^1)
Second, apply the rule a^1=a
y^1=y
m(x-x^1)=y-y
Third, add similar elements: y-y=0,
m(x-x^1)=0
Fourth, using the Zero Factor Principle: If ab=0 then a=0 or b=0
x-x^1=0
Finally, simplify,
0=0
Isaac invested $1,800 in an account paying an interest rate of 4.7% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest hundred dollars, would be in the account after 15 years?
Answer:
First, convert R as a percent to r as a decimal
r = R/100
r = 4.7/100
r = 0.047 rate per year,
Then solve for A,
[tex]A = P\cdot e^{rt}\\\\A= 1800 \cdot (2.71828)^{(.047)(15)}, \ where \ e = 2.71828\\A = 3642.92[/tex]
The amount he receives after 15years $3,642.92
. Allison drew a triangle with 2 congruent sides and 1 obtuse angle. Which terms accurately describe the triangle? Select all that apply.
Answer:
obtuse triangle
isosceles triangle
Step-by-step explanation:
A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
Area of a triangle = 1/2 x base x height
the perimeter of a triangle = sum of the side lengths
An isosceles triangle has two opposite sides. If the two angles are equal , it means the triangle is an isosceles. Because 90 degrees is greater than 45 degrees, the two sides with the same length, would have a smaller length than the third side.
Answer:
obtuse triangle
isosceles triangle

If a rectangular. Prism. Has 5cm. 10cm on one side and 4cm on the. Other. What is the volume of the rectangle?
Answer: [tex]200\ cm^3[/tex]
Step-by-step explanation:
Given
The dimension of the rectangular prism is
[tex]l=5\ cm\\w=10\ cm\\h=4\ cm[/tex]
The volume of the prism is given by [tex]V=l\times w\times h[/tex]
[tex]\Rightarrow V=5\times 10\times 4\\\Rightarrow V=200\ cm^3[/tex]
Therefore, the volume of the prism is [tex]200\ cm^3[/tex].
