Rewrite 2/5 book 1/2 hour as a unit rate
Answer:
4/5 book per hour
Step-by-step explanation:
In this question, we are to rewrite (2/5)/(1/2) as unit rate.
To write this as a unit rate, what we need to do
is to divide 2/5 by 1/2.
That means 2/5 divided by 1/2
Removing the division and replacing with multiplication will give 2/5 * 2/1 = 4/5 books/hour
Step-by-step explanation:
4/5 books/hour
Andrea is painting a ceramic plate with a diameter of 12 inches. She wants to paint a thin blue line around the edge of the plate. How long will the line be?
Answer:
37.7 inches
Step-by-step explanation:
She wants to paint the line along the circumference of the plate.
The plate is circular; the circumference of a circle is given as:
C = πD
where D = diameter
The diameter of the plate is 12 inches, therefore:
C = π * 12 = 37.7 inches
The line will be 37.7 inches long.

sorry if im too late
a = -3, and c = 7. What is the value of b?
Answer:
6.235
Step-by-step explanation:
c²=a²+b² (pythagorean theory)
7²=-3²+b²
49=9+b²
(49-9). 40=b² (find the square root of 40 to obtain the value of b)
If b=13 and A=76 degrees, then find a.
Answer:
Option (D).
Step-by-step explanation:
In the figure attached,
Triangle ACB is a right triangle having,
Leg AC = b = 13
Leg BC = a
Angle A = 76°
and, Hypotenuse AB = c
By applying tan rule in the given triangle,
tanA = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]
tan(76)° = [tex]\frac{BC}{AB}[/tex]
= [tex]\frac{a}{b}[/tex]
4.01 = [tex]\frac{a}{13}[/tex]
a = 13 × 4.01
a = 52.13
a ≈ 52.1
Therefore, Option (D). will be the answer.

An object in the shape of a rectangular prism has a length of 5 inches, a width of 3 inches, and a height of 2 inches. The object's density is 8.3 grams per cubic centimeter. Find the mass of the object to the nearest gram.
Answer:
[tex]4,080grams[/tex]
Step-by-step explanation:
the formula for density is:
[tex]d=\frac{m}{V}[/tex]
where d is density, m is mass, and V is volume.
solving for m in the last equation:
[tex]m=d*V[/tex]
so if we find the volume and multiply it by the density [tex]d=8.3gr/cm^3[/tex] we will get the mass of the object.
The volume of a rectangular prism is given by:
[tex]V=l*w*h[/tex]
where [tex]l[/tex] is length, [tex]w[/tex] is width and [tex]h[/tex] is height:
[tex]l=5in\\w=3in\\h=2in[/tex]
we substitute to find the volume:
[tex]V=5in*3in*2in\\V=30in^3[/tex]
since the density has units of [tex]cm^3[/tex] we need the volume also in units of [tex]cm^3[/tex] , so we make the conversion using:
[tex]1in^3=16.3871cm^3[/tex]
multiplying by 30:
[tex]30in^3=491.612cm^3[/tex]
and now we find the mass with the equation:
[tex]m=d*V[/tex]
substituting d and V:
[tex]m=(8.3gr/cm^3)(491.612cm^2)\\m=4,080.36gr[/tex]
the nearest gram is: [tex]4,080grams[/tex]

Answer:
V =94.2 cm^3
Step-by-step explanation:
The volume of a cone is
V = 1/3 pi r^2 h
The radius is 3 and the height is 10
V = 1/3 ( 3.14) 3^2 * 10

Select the correct answer. What are the solutions to this quadratic equation?
A)x=4+sqrt 10
B)x=-2+4 sqrt 10
C)x=4+2 sqrt 10
D)x=-4+4 sqrt 10
Answer:
Let's solve your equation
[tex]x^2+13=8x+37[/tex]
Step 1: Subtract 8x+37 from both sides.
[tex]x^2+13-(8x+37)=8x+37-(8x+37)[/tex]
[tex]x^2-8x-24=0[/tex]
For this equation: a= 1, b= -8, c= -24
Step 2: Use quadratic formula with a=1, b=-8, c=-24.
[tex]x=\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex]
[tex]x=\frac{-(-8)+\sqrt{(-8)^2-4(1)(-24)} }{2(1)}[/tex]
[tex]x=\frac{8+\sqrt{160} }{2}[/tex]
[tex]x=4+2\sqrt{10}[/tex] or [tex]x=4-2\sqrt{10}[/tex] This is the answer
So,the correct option is C

Jennifer is flying her kite and I get stuck in a tree. She knows the string on her coat is 17 feet long and she is 7 feet from the tree. How high up in the tree is the kite (in feet)?
Answer:
15.5 feet
Step-by-step explanation:
Find attached to this answer the appropriate diagram.
We would be using the Pythagoras Theorem to solve this question
The formula is given as:
a² + b² = c²
Where a = opposite side
b = adjacent side
c = hypotenuse
From the question,
a = opposite side = unknown
b = adjacent side = 7 feet
c = hypotenuse = 17 feet
We are to find the opposite side
Using the formula
a² + b² = c²
a² = c² - b²
a² = 17 feet² - 7 feet ²
a² = 289 feet² - 49 feet²
a² = 240 feet²
a = √240 feet²
a = 15.491933385 feet
Approximately 15.5 feet
Therefore, the kite is 15.5 feet high up in the tree.

A cube has a volume of 1/512 cubic meter. Complete the explanation for finding the length of each side of the cube. Express your answers as simplified fractions when necessary
Answer:
1/8 meters
Step-by-step explanation:
The volume of a cube is given as the cube of the length of its sides. That is:
[tex]V = L^3[/tex]
where L = length of its side
The volume of the cube is 1/512 cubic metres.
This implies that:
[tex]\frac{1}{512} = L^3[/tex]
Find the cube root of both sides:
[tex]\sqrt[3]{\frac{1}{512} } = L\\\\=> L = \frac{1}{8}[/tex] meters
The cube has sides of length 1/8 meters
