Answer:
8.9 seconds
Step-by-step explanation:
When caroline catches sam after some time lets say t
distance moved by Caroline will be 80 feet more than sam as they were 80 feet apart.
Given
Let the time taken by Caroline to catch sam is t seconds
distance covered by Caroline in t seconds = speed of caroline*t
distance covered by Caroline in t seconds = 31 * t
distance covered by Caroline in t seconds = 31t feet
distance covered by sam in t seconds = speed of sam*t
distance covered by sam in t seconds = 22 * t
distance covered by sam in t seconds = 22t feet
distance moved by Caroline will be 80 feet more than sam as they were 80 feet apart and caroline catches her in t seconds
thus,
distance covered by Caroline in t seconds = distance covered by sam in t seconds + 80 feet
31t = 22t + 80
subtracting 22t from both sides
=> 31t - 22 t = 80
=> 9t = 80
=>t = 80/9 = 8.9 seconds
Thus,
it will take 8.9 seconds for Caroline to catch Sam

What are the 4 major types of special Angle Pairs formed by Parallel Lines and Transversals? 20 points Vertical Angles, Angle Bisectors, Linear Pairs, Perpendicular Bisectors Alternate Interior, Corresponding, Consecutive Interior, Alternate Exterior Straight, Acute, Obtuse, Right Adjacent Angles, Supplementary Angles, Complementary Angles, Opposite Angles
Answer:
Alternate Interior, Corresponding, Consecutive Interior, Alternate Exterior
Step-by-step explanation:
When a transversal cuts across two parallel lines, there are 4 major types of special angles that are formed as shown in the attachment below. They are:
1. Alternate interior angle pairs are angles that are positioned inside the two parallel lines but lie on opposite sides of the transversal that cuts across the two parallel lines.
In the figure attached below, the alternate exterior angle pairs are labelled:
<3 and <6;
<4 and 5
2. Corresponding angles: these are angle pairs that are lie in the same position of the transversal, one interior, and the other exterior to a parallel lines respectively.
In the figure attached below: the following are corresponding angles pairs:
<1 and <5;
<2 and 6;
<3 and <7;
<4 and <8
3. Consecutive Interior angle pairs: these are angles that lie in the same side of the transversal and also found opposite each other within the parallel lines.
They are labelled:
<3 and <5;
<4 and <6
4. Alternate exterior angle pairs are angles that are positioned outside of the two parallel lines but lie on opposite sides of the transversal that cuts across the two parallel lines.
They are labelled:
<1 and <8;
<2 and <7;
find the gradient of the line segment between the points (0,3) and (1,8)
The gradient of the line segment between the points (0,3) and (1,8) is : 5
What is gradient?Gradient is the ratio of the increase or decrease in the y-coordinates to the increase ore decrease in the x-coordinates of points that form a line segment.
Analysis:
x1 = 0, x2 = 1, y1 = 3, y2 = 8,
Gradient(M) = [tex]\frac{y2 - y1}{x2 - x1}[/tex]
= [tex]\frac{8 - 3}{1 - 0}[/tex] = 5/1 = 5
In conclusion, the gradient of the given points (0,3) and (1,8) is : 5

Answer:
The numbers 4, 9, 25, and 49 are composite numbers.
The number 1 is a prime number.
Step-by-step explanation:
A prime number can be defined as a number that is divisible by 1 and itself only. Examples are: 1, 3, 5, 7, 11 e.t.c
A composite number can be defined as a positive number that can be formed by multiplying two smaller positive numbers together. These two positive integers may or may not be prime number.
It is a positive integer that has at least one divisor other than 1 and itself.
Examples are: 4, 6, 8, 9, 12, 25, 49, e.t.c
Therefore, the true statements in the questions above =
The numbers 4, 9, 25, and 49 are composite numbers.
The number 1 is a prime number.

-4/5 + 33/10 Write your answer as a mixed number in simplest form.
Answer:
2 1/2
Step-by-step explanation:
−45+3310=?
The fractions have unlike denominators. First, find the Least Common Denominator and rewrite the fractions with the common denominator.
LCD(-4/5, 33/10) = 10
Multiply both the numerator and denominator of each fraction by the number that makes its denominator equal the LCD. This is basically multiplying each fraction by 1.
(−45×22)+(33/10×11)=?
Complete the multiplication and the equation becomes
−8/10+33/10=?
The two fractions now have like denominators so you can add the numerators.
Then:
−8+33/10=25/10
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 25 and 10 using
GCF(25,10) = 5
25÷5/10÷5=5/2
The fraction
52
is the same as
5÷2
Convert to a mixed number using
long division for 5 ÷ 2 = 2R1, so
52=212
Therefore:
−4/5+33/10= 2 1/2

Onya selected a pair of shoes for the regular price of $80. How much money will she save by using the 20% off coupon? Justify your answer using equations, models, and/or words to explain your mathematical reasoning. Part B: Katie selected a pair of shoes for the regular price of $120. After the 20% off discount is applied, what will be the discounted cost of the shoes (before tax)? Justify your answer using equations, models, and/or words to explain your mathematical reasoning.
Answer:
a. [tex]Savings = \$16[/tex]
b. [tex]Price = \$96[/tex]
Step-by-step explanation:
Solving (a):
[tex]Price = \$80[/tex]
[tex]Coupon = 20\%[/tex]
Required
Determine her savings.
[tex]Savings = Coupon * Price[/tex]
[tex]Savings = 20\% * \$80[/tex]
[tex]Savings = \$16[/tex]
Solving (a):
[tex]Price = \$120[/tex]
[tex]Coupon = 20\%[/tex]
Required
Determine the price before tax
First, we need to determine her savings
[tex]Savings = Coupon * Price[/tex]
[tex]Savings = 20\% * \$120[/tex]
[tex]Savings = \$24[/tex]
The price before tax is calculated as follows:
[tex]Price = \$120 - \$24[/tex]
[tex]Price = \$96[/tex]

Answer: AB is 40
Step-by-step explanation: CD=CE+ED ED is 5 and it is also the midpoint meaning it is 1/2 of the value of the line. Therefore CD is 10, BC=BD+CD CD as we know is 10 and D is the mid point meaning it is also 1/2 of the value of BC. 10+10=20, AB=AC+BC, BC is 20 so AC must also be 20;therefore AB is 40

To transmit information on the internet, large files are broken into packets of smaller sizes. Each packet has 1,500 bytes of information. An equation relating packets to bytes of information is given by b = 1,500p where p represents the number of packets and b represents the number of bytes of information. Each byte contains 8 bits of information. Write an equation to represent the relationship between the number of packets and the number of bits. (X = form)
Answer: [tex]x= 187.5p[/tex]
Step-by-step explanation:
Given : An equation relating packets to bytes of information : [tex]b = 1,500p[/tex] where p represents the number of packets and b represents the number of bytes of information.
1 byte = 8 bits
Let x= Number of bits such that 1 b = 8x
Put b = 8x in given equation , we get
[tex]8x=1500p[/tex]
Divide both sides by 8 , we get
[tex]x= 187.5p[/tex]
Hence, the equation represent the relationship between the number of packets and the number of bits : [tex]x= 187.5p[/tex]
Answer:
x=12000p
