Tracy can type 45 words in 3 minutes. At that rate, how many minutes would it take Tracy to type 315 words?
Answer:
21 minutes
Step-by-step explanation:
The rate that she types is 15 words in a minute
315/15 =
21 or 21 minutes
Answer: It will take Tracy 21 minutes to type 315 words
Step-by-step explanation:
Set up a proportional relationship to solve for the number of minutes.
45 words = 3 mins
315 words = x mins.
[tex]\frac{45}{315} = \frac{3}{x}[/tex] Cross multiply
45x = 945 Divide both sides by 45
x = 21

b. What figure results from the reflection?
The figure resulting from the reflection RPO (PQRS) is a square.
Justify the solution to the previous step. Select the correct choice below and, if necessary, fill in the answer boxes within your choice.
O A. Since Rpp (P)=IS)Rp (P)=S', and reflections preserve distance, Rpõ(PS)=PS. SO, QR=PS' and SS'=2QR. Using PQ = 2QR, SS -ss'. Therefore, the
length equals the width in the new figure.
B. Since reflections preserve distance, Rpo (PS)=PS' and Rpo(QS)=QS'. Thus, there are two pair of line segments with the same length.
OC. Since reflections preserve distance, Rpg=PS. There is no useful relationship between and SQ that can be used. Thus, only 2 sides have the same
length

The volume of a cylinder is 4πx3 cubic units and its height is x units. Which expression represents the radius of the cylinder, in units? 2x 4x 2πx2 4πx2
Answer:
It's A
Step-by-step explanation:
The expression that represents the radius of the cylinder is 2x
What is volume?The volume of a shape (e.g. cylinder) is the amount of space in the shape i.e. the cylinder
Below, is how to calculate the radius of the cylinder
The volume is given as:
V = 4πx³
The volume of a cylinder is:
V = πr²x
By comparison, we have:
πr²x = 4πx³
Divide the common factors
r² = 4x²
Take the square root of both sides
r = 2x
Hence, the expression that represents the radius of the cylinder is 2x

Juan needs to take an Uber to get to the movies. The Uber charges $1.50 for the first mile, and then $1.55 for each mile after that. If the total charge is $10.49, then how far was Juan’s Uber ride to the movie?
Answer:
5.8 miles were travelled by Juan's Uber ride to the movie.
Step-by-step explanation:
Let x = miles travelled by Juan
Charges for first mile = $1.50
Charges for each mile after first = $1.55
Total charge for Juan = $10.49
We need to find how many miles Juan covered?
The equation will be:
[tex]1.50+1.55(x)=10.49[/tex]
We will solve this equation to find value of x
Solving:
[tex]1.50+1.55(x)=10.49[/tex]
Subtracting 1.50 from both sides
[tex]1.50+1.55(x)-1.50=10.49-1.50\\1.55(x)=8.99\\x=\frac{8.99}{1.55} \\x=5.8[/tex]
So, 5.8 miles were travelled by Juan's Uber ride to the movie.

Ab and c lie on a straight line BD=CD BCD=15 BAD=5 Work out x
Answer:
[tex]x = 10[/tex]
Step-by-step explanation:
The attachment completes the question;
From the question, we have the following given parameters
[tex]BD = CD[/tex]
[tex]\angle BCD = 15\deg[/tex]
[tex]\angle BAD = 5\deg[/tex]
Required
Solve for x
Since [tex]BD = CD[/tex] then
[tex]\angle CBD = \angle BCD[/tex] --- Property: Base angle of an isosceles triangle
[tex]\angle CBD = \angle BCD = 15[/tex]
Also, ABC is a straight line;
So:
[tex]\angle CBD + \angle DBA = 180[/tex] --- angle on a straight line
Substitute 15 for [tex]\angle CBD[/tex]
[tex]15 + \angle DBA = 180[/tex]
Make [tex]\angle DBA[/tex] the subject
[tex]\angle DBA = 180 - 15[/tex]
[tex]\angle DBA = 165[/tex]
Considering triangle DBA
[tex]\angle DBA + \angle BAD + x = 180[/tex] ---- angles in a triangle
Substitute 165 for [tex]\angle DBA[/tex] and 5 for [tex]\angle BAD[/tex]
[tex]165 + 5 + x = 180[/tex]
Make x the subject
[tex]x = 180 - 165 -5[/tex]
[tex]x = 10[/tex]

what is 24 divided by 8/15
Answer:
45
Step-by-step explanation:
put 24 over 1 to make it a fraction.
So now its:
24/1 divided by 8/15
Now cross multiply
So now its:
24*15/1*8
(24 times 15)
Over
(1 times 8)
=360/8
=45
24 divided by 8/15 is equal to 45.
To divide 24 by 8/15, we can simplify the problem by multiplying 24 by the reciprocal of 8/15, which is 15/8. Multiplying fractions involves multiplying the numerators and denominators.
So, 24 divided by 8/15 can be rewritten as 24 multiplied by 15/8:
24 * (15/8)
When we multiply the numerators (24 * 15) and the denominators (1 * 8), we get:
360/8
Simplifying the fraction by dividing both the numerator and denominator by their greatest common factor, which is 8:
45/1
Therefore, 24 divided by 8/15 is equal to 45.
