A photo 5 inches wide and 8 inches long is enlarged. How long is the new photo if it is How wide is the new photo if it is (1)12 inches; (2)20 inches; (3)10 inchs

Answers

Answer:

1) 7.5 inches, 2) 12.5 inches, 3) 6.25 inches

Step-by-step explanation:

In the problem statement, it is stated that the original dimensions of the photo are 5 inches by 8 inches. The 3 parts of the problem are asking what the respective width of the new photo would be given a different length measurement.

Using the ratio (5:8) you can set up an equation with x representing the missing measurement, and cross multiply to calculate the new width.

1) If the length is 12 inches, the width is 7.5 inches

[tex]\frac{5}{8} = \frac{x}{12}[/tex]

[tex]60=8x[/tex]

[tex]\frac{60}{8} =x[/tex]

[tex]7.5 = x[/tex]

2) If the length is 20 inches, the width is 12.5 inches

[tex]\frac{5}{8} = \frac{x}{20}[/tex]

[tex]100=8x[/tex]

[tex]\frac{100}{8} =x[/tex]

[tex]12.5 = x[/tex]

3) If the length is 10 inches, the width is 6.25 inches

[tex]\frac{5}{8} = \frac{x}{10}[/tex]

[tex]50=8x[/tex]

[tex]\frac{50}{8} =x[/tex]

[tex]6.25 = x[/tex]

4 1/2 + 1 3/5
What is the sum because I’m very slow

Answers

First, chance the fractions so the denominators are the same. The GCF of these is 10, so multiple both numerators and denominators so the denominator is 10.

1/2 = 5/10

3/5 = 6/10

Add the wholes and the fractions:

5 11/10

Since the numerator is higher than the denominator, we can make another whole:

11/10 - 10/10 = 1/10

So 5 becomes 6 because of the whole:

5 + 1 = 6

The fraction becomes 1/10:

So the final answer is:

6 1/10

(Important Note: Unless asked, you must always put fractions into its smallest form, meaning numerator can NEVER be higher than the demoninator. When you do this process, do not forget to add the whole number or else you will be incorrect.)

(Second note: its not GCF its closest product they have.)

Answer:

6 1/10

Step-by-step explanation:

convert mixed fraction to improper fraction

4 1/2 + 1 3/5

= (4*2 + 1) / 2 +  (1*5 + 3) / 5

= 9/2 + 8/5

= lcm of 2 and 5 = 10

= (5 * 9 + 8 * 2)  /10

= (45 + 16)  /10

= 61/10

= (60 + 1) / 10

= 6 1/10

The cost of 4 books is $18.00 and the cost of 4 pens is $20.00. Find the cost of six similar
books and six similar pens.

Answers

4 books is 18.00
18/4 is 4.5
$4.50 per book

4 pens is 20.00
20/4 is 5
$5.00 per pen

6 books $4.50 each
6(4.50) = $27

6 pens $5.00 each
6(5) = $30

6 books is $27
6 pens is $30
6 books = $27 and 6 pens = $30
4 books = $18 so divide 18 by 2 get 9 so 2 books are $9 just add $18 to $9 to get $27
4 pens = $20 so divide 20 by 2 get 10 so 2 pens = $10 just add $20 to $10 to get $30

HELP ASAP You are preparing to move into a new house. The walls of your room will measure 10 feet by 12 feet.
When you look at the blueprint, the lengths of the walls on the drawing are 7.5 inches by 9 inches. What
is the scale used on the blueprint?

Answers

The Scale used on blueprint is 1 inches represents 4/3 feet

Scaling is the increase or decrease in size of a figure or object so as to create an image of that object.

Since on the blueprint, the walls measure 10 feet by 12 feet but on the blue print it measures 7.5 inches by 9 inches. Hence:

Scale used on blueprint is 7.5 inches = 10 feet or 9 inches = 12 feet

1 inches = 4/3 feet

The Scale used on blueprint is 1 inches represents 4/3 feet

Answer:

B. 39

Step-by-step explanation:

134 is a supplementary angle, so 180-134=46. 46 is the bottom left interior angle of the triangle.

Next that 56 and the bottom right exterior angle are supplementary, so 180-56=124.

now we have the bottom right exterior angle, to find the interior 180-124=56.

Then we can set up the equation to find x:

56+46+2x=180

we have 180 because all triangles angle equal 180.

calculate the equation:

combine like terms, (2x)+(56+46)=180

2x+102=180

Subtract 102 from both sides,

180−102=78

2x=78

Divide both sides by 2.

78/2=39

x=39.
