Angel bought 8 oranges and 11 apples for a total of $15.22. He knows that each orange costs $0.50 and reasoned that each apple must cost a little more than $1.00. Is the answer reasonable why or why not?

Answers

Answer 1

Answer: find cost of apples
total=oranges+apples
total-oranges=apples

0.5=1/2
cost of oranges=8 times 0.5=8 times 1/2=4

total=15.22
oranges=4
15.22-4=apples
11.22=11 apples
we can see that if the apples were 1 dollar each then the cost woud be $11, but is is more, so it is a little more than $1 each

correct, because of math

Answer 2

Answer: he is correct
.50x8=4 15.22-4=11.22 11.22/11=1.02

Rachel made a mosaic from different color rectangle tiles 3 tiles measured three and a half inches x 3 inches 6 tiles measures 4 inches x 3 1/4 inches what is the area of the whole mosaic in square inches

Answers

so assuming that the only had 3+6=9 tiles
what we have to do it find teh area total
area=legnth times width

3 tiles are 3 and 1/2 times 3
3 times 3 and 1/2=10 and 1/2
times 3 tiles
10 and 1/2 times 3=31 and 1/2 squar inches

6 tiles are 4 by 3 and 1/4
4 times 3 and 1/4=13
6 tiles times 13 inchessquare=78

so we add
31 and 1/2+78=109 and 1/2 square inches

109 ¹/₂ in²

Further explanation

Given:

Rachel made a mosaic from different color rectangle tiles.
Three tiles measured 3 ¹/₂ inches x 3 inches.
Six tiles measured 4 inches x 3 ¹/₄ inches.

Question:

What is the area of the whole mosaic in square inches?

The Process:

Let's use the formula of a rectangular area.

$\boxed{\boxed{ \ Area = length * width \ }}$

Part-1: three tiles measured 3 ¹/₂ inches x 3 inches.

The area of the three tiles is as follows:

$\boxed{ \ Area = 3 * length * width \ }$

$\boxed{ \ Area = 3 * 3 * 3(1)/(2) \ }$

$\boxed{ \ Area = 3 * 3 * (7)/(2) \ }$

$\boxed{ \ Area = 9 * (7)/(2) \ }$

$\boxed{\boxed{ \ Area = (63)/(2) \ in^2\ }}$

Part-2: six tiles measures 4 inches x 3 ¹/₄ inches.

The area of the six tiles is as follows:

$\boxed{ \ Area = 6 * length * width \ }$

$\boxed{ \ Area = 6 * 4 * 3(1)/(4) \ }$

$\boxed{ \ Area = 6 * 4 * (13)/(4) \ }$

$\boxed{ \ Area = 24 * (13)/(4) \ }$

Both 24 and 4 are divided by 4.

$\boxed{ \ Area = 6 * 13 \ }$

$\boxed{\boxed{ \ Area = 78 \ in^2 \ }}$

Finally, let's add up the two areas above to get the area of the whole mosaic.

$\boxed{ \ = (63)/(2) + 78 \ }$

$\boxed{ \ = 31(1)/(2) + 78 \ }$

$\boxed{ \ = 109(1)/(2) \ }$

Thus, the area of the whole mosaic is $\boxed{\boxed{ \ = 109(1)/(2) \ in^2 \ }}$

Reorder the following equations in ascending order of steepness.y = 15x + 5y = 0.15x - 1y = xy = x + 100

Answers

Equations don't have steepness. "Steepness" is the slope of the line you get when you graph the equation. If you always massage the equation into the form
[ y = (something times x) + something },
then the number that multiplies 'x' is the slope of the graph..

y = 15x + 5
The slope is 15.

y = 0.15x - 1
The slope is 0.15 .

y = x
The slope is 1. ( y = 1x )

y = x + 100
The slope is 1. ( y = 1x + 100 )

In 2004, there were 19,396 bulldogs registered by the American Kennel Club. Approximately 86% of this number were registered in 2003. About how many bulldogs were registered in 2003?

Answers

To solve this problem you must find 86% of 19,396.
To do this, let's start by turning 86% a decimal to multiply.
86% will become 0.86
Now, we multiply 0.86 by 19,396.
We get the answer, 16680.56
The question says about, so we need to round it.
When rounded we get 16681.
That means 16681 bulldogs were registered in 2003.
Hope this helped you! :)

when the whole is the same why does it take 4 copies of one tenth to equal 2 copies of one fifth draw a model to support your answer

Answers

well 4 copies of one tenth will equal 4 tenths. so when u simplify 4 over ten (4/10 )and divide the top and bottom by the common factor which is 2 then you will get 2 fifths because 4 divided by 2 is 2 and 10 divided by 2 is 5.
