Answer:
190.47 (190 47/100)
Step-by-step explanation:
First, you need to find a common denominator, which is 100. So multiply 3/10 by 10 with both the numerator and denominator. So your new equation should be 382 30/100 - 191 87/100. Even though 382 is larger than 191, 3/100 is still less than 87/100. So what you do is cross out the first/whole number and then add the denominator.
Hope this helped! <3
Answer:
190.43
Step-by-step explanation:
Convert the denominator to 100
> 382 30/100 - 191 87/100
Subtract the whole numbers and the fractions separately
> (382 -191) + (30/100 - 87/100)
> 191 + (-57/100)
> 190 43/100
= 190.43
Tara owns a pizza shop. The item purchased most frequently from her shop is a large pizza. For any order, Tara charges $7.00 for each pizza plus $3.00 for delivery services. Tara made a delivery of pizzas to a party for which she charged $45.00. How many pizzas did she deliver?
Answers
Answer:
Tara delivered 6 pizzas in total
Step-by-step explanation:
Tara charges $45.00 but delivery is $3.00 so you take away $3.00 from the total that was charaged and we are left with $42.00 so then all you have to do now is divide the $42 with $7 and that will give you 6 so the final answer would be 6 pizzas

Step-by-step explanation:
Step 1:
Start by setting it up with the divisor 7 on the left side and the dividend 9 on the right side like this:
7 ⟌ 9
Step 2:
The divisor (7) goes into the first digit of the dividend (9), 1 time(s). Therefore, put 1 on top:

7 ⟌ 9
Step 3:
Multiply the divisor by the result in the previous step (7 x 1 = 7) and write that answer below the dividend.

Step 4:
Subtract the result in the previous step from the first digit of the dividend (9 - 7 = 2) and write the answer below.

For something to be 'irrational', you shouldn't be able to put it in a fraction. You can know if something is irrational because when you look at it in decimal form and the numbers after the decimal point are random and do not follow a pattern (ie 276276276...).
Hence that is why pi is irrational as well because the numbers after the dec. point are: 3.1415626.... there is no visible pattern
A truck can be rented from Company A for $130 a day plus $0.30 per mile. Company B charges $40 a day plus $0.60 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Answers
Answer: 300 miles
Step-by-step explanation:
Let x= Number of miles driven by both cars.
As per given,
For Company A
Charges = $130 a day plus $0.30 per mile.
i.e. Total charge = 130+0.30x
For Company B
Charges =$40 a day plus $0.60 per mile
i.e. Total charge =40+0.60x
When the rental cost for both company is same,
40+0.60x=130+0.30x
⇒ 0.60x-0.30x= 130-40
⇒ 0.30x= 90
⇒ x= 90÷0.30
⇒ x= 300
hence, the number of miles in a day at which the rental costs for Company A and Company B are the same = 300

Options:
[tex]3x + 4y = -10[/tex]
[tex]3x - 4y = 10[/tex]
[tex]3x + 4y = 10[/tex]
[tex]3x - 4y = -10[/tex]
Required
Select which option answers the question
Analyzing the options one after the other:
Option 1: [tex]3x + 4y = -10[/tex]
Represent the given equation as equation 1 and the option as equation 2;
So, we have:
[tex]3x + 4y = 10[/tex]
[tex]3x + 4y = -10[/tex]
Subtract equation 2 from 1:
[tex]3x - 3x + 4y - 4y = 10 -(-10)[/tex]
[tex]0 + 0 = 10 +10[/tex]
[tex]0 = 20[/tex]
Since,
[tex]0 \neq 20[/tex]
We can conclude that both equations has no solution
Hence:
Option 1 answers the question and there's not need to check for other options

Read this passage about Amelia Earhart.
Amelia Earhart was born July 24, 1897, in Kansas. She was an adventurous and fun-loving child. That adventurous spirit remained as she grew older. One day in 1920, after going on a plane ride, she was determined to fly planes. She worked at any job she could find to save up for flying lessons, which cost $1,000. At one point, she worked as a nurse’s aid and a social worker. Six months after receiving flying lessons, Amelia bought her own plane, and she flew as high as 14,000 feet, which set a world record for female pilots. A short time afterward, Amelia became the sixteenth female to earn a pilot’s license. In 1928, an opportunity arose for Amelia to participate in a transatlantic flight across the Atlantic Ocean as a copilot. This experience later came in handy when she became the first woman to fly solo across the Atlantic in 1938. She received many honors for this achievement, such as the Distinguished Flying Cross from Congress.
As Amelia approached her fortieth birthday, she was planning her biggest trip yet: She wanted to be the first woman to fly around the world. Of course, she needed a lot of help to make this happen. She made a first attempt that failed and damaged her plane. But Earhart was not one to give up, so she made another attempt at the ground-breaking mission. She did make some progress by flying 7,000 miles to New Guinea but did not make it to her next stop, Howland Island. Sadly, Earhart’s plane disappeared, and, despite search and rescue attempts, she was never found. To this day, Earhart is known and celebrated for her bravery, persistence, and commitment to aviation.
A yearbook page for Amelia Earhart includes "Amelia's Pet Peeve: Not Being Adventurous." Which image would best illustrate this?

Mary sells lemonade, and she sells 10 cents from ever cup she sells to charity. The cups of lemonade are 45 cents. One day she made $17.10. How much money did she to charity that day.
Answers
Answer:
$3.80
Step-by-step explanation:
Given that:
One cup of lemonade is sold at 45 cents.
Total money made = $17.10
Number of cups of lemonade sold can be found by dividing the total money made with the sale price of one cup of lemonade.
Number of cups of lemonade sold = [tex]\frac{\$18.10}{45\ cents} = \frac{\$18.10}{\$0.45} =38[/tex]
For each cup sold, 10 cents are donated.
Total money donated = 38 [tex]\times[/tex] 10 = 380 cents = $3.80
Therefore, the answer is:
Total money donated by Mary is $3.80

A rectangle has a height that is 5 inches less than the base. If the area of the rectangle is 57 inches square, what are the height and base of the rectangle?
Answers
Answer:
The height and base of the rectangle are approximately 5.453 inches and 10.453 inches, respectively.
Step-by-step explanation:
From Geometry we remember that area of a rectangle ([tex]A[/tex]), measured in square inches, is equal to:
[tex]A = w \cdot h[/tex] (Eq. 1)
Where:
[tex]w[/tex] - Width, measured in inches.
[tex]h[/tex] - Height, measured in inches.
In addition, we get the following relationship from statement:
[tex]w = h+5\,in[/tex] (Eq. 2)
If we know that [tex]A = 57\,in^{2}[/tex], then the height of the rectangle is:
[tex]57\,in^{2} = (h+5\,in)\cdot h[/tex]
[tex]h^{2}+5\cdot h -57 = 0[/tex]
From Quadratic Formula we obtain the following roots:
[tex]h_{1} \approx 5.453\,in[/tex] and [tex]h_{2}\approx -10.453\,in[/tex]
Only the first root offers a reasonable solution, as length has always positive values. Thus, the height of the rectangle is approximately 5.453 inches.
Now we calculate the width of the rectangle from (Eq. 1):
[tex]w = \frac{A}{h}[/tex]
If we know that [tex]A = 57\,in^{2}[/tex] and [tex]h \approx 5.453 \,in[/tex], then the width of the rectangle is:
[tex]w = \frac{57\,in^{2}}{5.453\,in}[/tex]
[tex]w \approx 10.453\,in[/tex]
The height and base of the rectangle are approximately 5.453 inches and 10.453 inches, respectively.
