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
The 150 Grade 7 students participated in school's Math Olympics. 64 students registered in Math Trail , 78 students registered in Amazing Race and 28 students registered in both Math Trail and Amazing Race. How many students registered in Math Trail only and in Amazing Race only? Are there students who did not registered in both events, how many?
Answer:
Number of students registered in Math trail only and in Amazing Race only is 86.
Number of students who did not registered in both events = 36
Step-by-step explanation:
There are 150 students totally.
64 students registered in Math trail.
78 registered in Amazing race.
28 registered in both Math trail and Amazing Race.
We can make Venn diagram for this and answer the question.
I've attached the Venn diagram.
Using the diagram,
Number of students registered in Math trial only and in Amazing race only is 36+50= 86.
Number of students who did not registered in both events = (150-(36+28+50))=36

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]

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

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;

These are statements about factors and prime and composite numbers. Which statements are true? Check all that apply. The numbers 4, 9, 25, and 49 are composite numbers. The number 1 is a prime number. The first prime number is 2. A composite number can be written as the product of prime numbers.
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.

a.$12 per month
b.$18 per month
c.$24 per month
d.$36 per month
Answer:
The answer is C., $24 per month.
Answer:
A $12
Step-by-step explanation:
she has saved $36 before she gets a part time job, after 2 months, her savings have increased from 36 to 60. 2 months = 60 - 36, 2 months = 24. now we divide 24 by 2, and the answer is 12. option A is correct.

Gabriel is raising money for a school trip by selling lollipops and bags of chips. The
price of each lollipop is $1 and the price of each bag of chips is $1.50. Yesterday
Gabriel made $30 from selling a total of 26 lollipops and bags of chips. Graphically
solve a system of equations in order to determine the number of lollipops sold, 2,
and the number of bags of chips sold, y.
Answer:
There will be 2 bags of chips sold
Step-by-step explanation:
A system of equation is a collection of one or more equation involving the same variables.
Now , according to question :
since , he had sold 26 lollipop , then total money he made from lollipop is : 26 * $1 = $26
Let us assume he sold x number of chips
money made from chips = $ 1.50 * x
Total money made : $30 (Given )
equation according to question will be
26 + 1.50 x = 30
x= 2.7
Since , number of packets can never be in decimal hence, rounding off to 2 packets
x= 2
