The fraction of the album that is still empty is 28/100, the correct option is A.
What is a fraction?A fraction represents a part of a number or any number of equal parts.
A fraction consisting of a quotient and remainder is a mixed fraction. we can convert the mixed fraction to improper fraction by first dividing the numerator by denominator and then taking the quotient as whole number and remainder as the numerator of proper fraction keeping the denominator same.
We are given that;
The fraction 42/100
Now,
To rewrite 3/10 with a denominator of 100, we need to multiply both the numerator and denominator by 10. This gives us:
3/10 = (3 × 10) / (10 × 10) = 30/100
Now, we can add the numerators of the fractions and write the sum over the common denominator.
42/100 + 30/100 = (42 + 30) / 100 = 72/100
Therefore, the total fraction of the album that is filled with football and baseball cards is 72/100.
we need to subtract the fraction that is filled from the whole fraction, which is 1 or 100/100. To subtract fractions, we need to have a common denominator, which we already have as 100. So, we can subtract the numerators of the fractions and write the difference over the common denominator.
100/100 - 72/100 = (100 - 72) / 100 = 28/100
Therefore, the fraction will be 28/100.

(0.5x+1.2)–(3.6–4.5x)=(4.8–0.3x)+(10.5x+0.6)
Answer:
x = -1.5
Step-by-step explanation:
(0.5x+1.2)–(3.6–4.5x)=(4.8–0.3x)+(10.5x+0.6)
*I would first change any minus signs that are outside of the parenthesis to a plus sign. This is optional, not necessary. *
0.5x + 1.2 + (-3.6) + 4.5x = 4.8–0.3x + 10.5x + 0.6
*Now combine like terms on each side. *
5x + (-2.4) = 10.2x + 5.4
*move all Xs on one side.*
-5.2x = 7.8
*Divide both sides by -5.2 to get X by itself."

Each rectangle in the diagram measures 3 cm by 6 cm. What is the length, in centimetres, of the longest path from A to B? You may travel in any direction, but no segment may be traced more than once. Show your answer on the diagram below by using arrows to indicate the directions you travel.
The longest path from A to B is 36 cm.
It is given that each rectangle in the diagram measures 3 m by 6 cm.
It is required to find the longest path from A to B.
What is the area of the rectangle?It is defined as the space occupied by the rectangle which is planner 2-dimensional geometry.
The formula for finding the area of a rectangle is given by:
Area of rectangle = length × width
We have a rectangle.
Each rectangle's dimensions are 3 cm by 6 cm means:
The width of each rectangle = 3 cm
The length of each rectangle = 6 cm
In the figure, if calculate the total length of the left side that is:
= 6+6+6
=18 cm
And topside width:
=3+6+6+3
=18 cm
We can say we a rectangle having dimensions 18 by 18.
If we travel from any path the total length will be covered from A to B:
= 18 + 18
=36 cm
As per the direction, we can calculate different path distances.
Thus, the longest path from A to B is 36 cm.

Step-by-step explanation:
Answer:
1. 78 ounces
2. 52 ounces
3. 12 guests
Step-by-step explanation:
1. Consider 6 ounces of dough and 4 ounces of sauce for each person as a set. So 1 set will have 10 ounces. Then, we divide the total ounces, 130 ounces by 10, which will give us 13 sets or people.Then, to find the ounces of dough,just multiply 6 ounces by 13 which will give us 78 ounces.
2. Similar to previous one, just multiply 4 ounces by 13 which will give us 52 ounces or simply minus 78 ounces from 130.
3. We obtained 13 sets(people) from number 1. Minus one (the host, yourself) from 13, we'll get 12.

Answer:
(X + 1) , (Y - 8)
Step-by-step explanation:
With this type of question, I usually like to follow one point as the others will follow the same rules. The Y coordinates of all of H'I'J'K' have been lowered drastically when compared to the original shape, so one can assume that the Y level is not increasing, especially as C would take half the points right off the grid.
By taking H's original coordinate point (in orange) we can see that it moves one forward in the X direction, or +1. Meanwhile, it moves eight down in the Y direction, or -8. Therefore, (X + 1), (Y - 8)

Tell me if the image is blurry in the comment section not the answer section Thankyou
Answer:
The explanation on how to do them is down below. If you have anymore questions pls feel free to ask
Step-by-step explanation:
So for number one you just need to state the sentence under the lines back wards but starting Lines m and n......
For number two name two angles that are inside the parallel lines and for three the opposite name two that are basically verticle outside of the parallel lines.
For number four they are across from each so they are verticle and since they are verticle they are concurrent so the m of 2 is 125.
In number 5,4 and 7 are corresponding so the are equal.
In number 6 the angles are alternate interior so they are congruent.
In number 7, the angles are corresponding so they are congruent.
In number 8, the angles are alternate exterior so they are congruent.
In number 9, the angles are are verticle so the are congruent.
In number 10, the answer is supplementary because on the top and bottom they add up to 180 degrees. And it part b 2 and 3 are adjacent and supplementary, so you subtract 119 from 180 and you get 61.
18.84 cm
37.68 cm
28.26 cm
113.04 cm
Answer:
(a) 18.84 cm
Step-by-step explanation:
The circumference of a circle is given by the formula ...
C = 2πr . . . . . for radius r
A circle of radius 3 cm will have a circumference of ...
C = 2(3.14)(3 cm) = 18.84 cm
_____
Additional comment
The area is ...
A = πr² = 3.14(3 cm)² = 28.26 cm²
The units of area are not cm, but are cm². This question asks for circumference. The shading may be misleading.
In 2016, a maglev train in Japan traveled 1.1 miles in 1045 seconds.
A picture of a Maglev train is shown. The caption reads Maglev trains use magnets to hover above the tracks. This helps them reach extraordinary speeds.
Question 1
Part A
Find the speed of the train in miles per hour.+
Answer: ~3.8 mph (see below)
Explanation:What we know:
We need to find the speed of the train in miles per hour (mph)The train is traveling 1.1 miles per 1045 secondsThere are 3600 seconds in 1 hourHow to solve:
We need to find what number when multiplied with 1045, will equal 3600. The unknown will be a variable x, and the seconds will be represented with s. Then, we need to multiply this number with the value of the miles (m) to find how many miles are traveled in that hour (h).
Process:Finding X (in seconds)
Set up equation H = sx
Substitute 3600 = 1045x
Divide /1045 /1045
Solution 3.44497608 = x
Finding Miles
Set up equation mph = x(m/s)
Substitute mph = 3.44497608(1.1/1045)
Simplify mph = ~3.79/3600
Convert mph = ~3.8 miles per hour
Solution: ~3.8 mph (3.78947369 miles per 3600 seconds)

new answer with estimate= 10 old answer= [tex]9.24[/tex]
Step-by-step explanation:
Use this method percent proportion
[tex]\frac{Percent}{100} = \frac{Part}{Whole}[/tex] or [tex]\frac{Percent}{100} = \frac{is}{of}[/tex]
Answer:
12% of 77
[tex]\frac{12}{100} = \frac{x}{77} = \frac{100x}{100} = \frac{924}{100} x = 9.24[/tex]
Steps:
1. Make a proportion with the method percent proportion.
2. After setting up numbers in proportion cross-multiply.
3. Make 100x because we don't know the value of x.
4. After multiplying 12 x 77 you should've gotten 924.
5. After cross-multiplying divide your new proportion.
6. [tex]x= 9.24[/tex] estimate = 10
now I'm not sure if those number in your question is your new estimate answer but since 9.24 is close to 10 your answer will be 10

Answer:
well first you would need to find the lowest common denominator for both of these which would be 15 and then divide the top number by the number it takes the denominator to get to 15 which for 2/3 it would become 10/15 and 2/5 would be 6/15 and since the equation wants how much she got rid of it would be 10/15-6/16 which equals 4/15 as your answer which you might be able to simplify

Estimate both:
903.6 ÷ 25.1 =
and 760.38 ÷ 0.38
Answer:
1. 36
2. 2000
Step-by-step explanation:
Step-by-step explanation:
903.6 ÷ 25.1 = 36 (exact answer).
900 ÷ 30 = 30 (estimated). As 903.6 near to 900 and not to 1000, and 25.1 near to 30 and not to 25 the equation is 900 ÷ 30 = 30.
760.38 ÷ 0.38 = 2001 (exact answer).
In the estimated answer Im not so sure about it so I leave you four choices.
1. 800 ÷ 0.40 = 2000 (rounded to the nearest ten)
2. 800 ÷ 0.00 = Infinity (0.38 close to a whole)
3. 800 ÷ 1 = 800 (0.38 not close to a whole)
4. 800 ÷ 40 = 20 (possibly the wrong answer not even close to 0.38)
