Nick has an album that holds 800 photos. Each page of the album holds 8 photos.
If 22% of the album is empty, how many pages are filled with photos?
Answer:
78 pages
Step-by-step explanation:
Find out 22% using 1% of the number of photos the album can hold.
100% = 800
1% = 800 ÷ 100 = 8
22% = 8 x 22 = 176
800 - 176 = 624
The album has 624 photos.
If 8 photos can create a page...
624 ÷ 8 = 78 pages

The oldest child in a family of four children is twice as old as the yougest. The two middle children are 12 and 16 years old. If the average age of the children is 15.25 , how old is the youngest child?
The age of the youngest child will be 11 years old.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
The oldest child in a family of four children is twice as old as the youngest.
Let x be the age of the youngest child and y be the age of the oldest child. Then the equation is given as,
y = 2x ...1
The two middle children are 12 and 16 years old. If the average age of the children is 15.25. Then the equation is given as,
(x + 12 + 16 + y) / 4 = 15.25
x + y = 33 ...2
From equations 1 and 2, then we have
x + 2x = 33
3x = 33
x = 11
The age of the youngest child will be 11 years old.

SPORTS A coach uses a metric to determine the athletes that make the Varsity, Junior Varsity A, and Junior Varsity B teams. The total number of points possible on a skills test is 350. Athletes will make "Varsity" with at least 90% of the points. Athletes will make "Junior Varsity A" for 70-89% of the points. Athletes will make "Junior Varsity B" for 50-69% of the points. The table shows the number of points for each athlete that tried out.
Answer:
there is no picture. :)
Step-by-step explanation:
Answer:
Varsity = 12
Jr Varsity A = 10
Jr Varsity B = 11
Step-by-step explanation:
Varsity = at least 90% = 350 times 90% = 315
Anything 315-350
Jr Varsity A = 70-89%
350 times 70% = 245
350 times 89% = 311.5
Jr Varsity b = 50-69%
350 times 50% = 175
350 times 69% = 241.5

Of the 400 6th grade students at Aviara Oaks Middle School, the ratio of boys to girls is 2:3. Of the 360 students at Valley Middle School, the ratio of boys to girls is 3:5.
Which middle school has more boys attending their school?
How many girls attend AOMS?
How many girls attend VMS?
What is the ratio of girls attending Aviara Oaks Middle School to girls attending Valley Middle School?
Answer:
Step-by-step explanation:
Aviara Oaks Middle School:
Total student = 400
Boys : girls = 2:3
Boys = 2x , girls = 3x
2x + 3x = 400
5x = 400
x = 400/5
x = 80
Number of boys = 2x = 2*80 = 160
Number of girls = 3x = 3 *80 = 240
VMS:
Total student = 360
Boys : girls = 3 : 5
Number of boys = 3x
Number of girls = 5x
3x + 5x = 360
8x = 360
x = 360/8
x = 45
Number of boys= 3x = 3 *45 = 135
Number of girls = 5x = 5 * 45 = 225
AOMS school has more boys attending their school.
Ratio of girls attending Aviara Oaks Middle School to girls attending Valley Middle School = 240 : 225
= 48 : 45

Answer:
x=36
Step-by-step explanation:
2x+2x+x+4-2-2=180
Combine Like Terms
5x=180
Divide
x=36
Answer:
we know that if we add all of the angles it adds up to 180 degrees
Step-by-step explanation:
so 180=(x-2)+(2x+4)+(2x-2)
combine like terms
180=5x
divide by 5 to isolate variable
x=36
If you need to find for an angle apply the x value into the given equation

Given :
segment AB = segment ADsegment BC = segment DC∠B =∠Dsegment AC bisects ∠BADThis means that △ABC≅△ADC under the SAS congruence criterion because according to this criterion if two sides and one included angle is equal two triangles are congruent and since these two triangles fulfill these rules they are said to be congruent under the SAS congruence criterion. But they are also congruent under the ASA congruence criterion which states that if two angles and one included side is equal two triangles are congruent. Since △ABC and △ADC fulfill these rules too they can said to be congruent under the ASA congruence criterion.

A man goes into a store and says, “If you give me as much money as I have with me now, I will spend $10 in your store.” The store owner agrees, and the man spends the money.
He goes into a second store and again says, “If you give me as much money as I have with me now, I will spend $10 in your store.” Again, the owner agrees, and the man spends the money.
In a third store, he repeats his proposition. The proprietor agrees, and the man spends the money.
At this point, the man has no money left. How much money did he have to begin with?
Answer:
$8.75
Step-by-step explanation:
Let x = the amount the man originally had
The man has $x and says "if you give me $x, I will spend $10."
y = amount he has after 1st proposition = x + x - 10 = 2x - 10
He repeats this procedure, now with $2x-10 in his pocket...
z = amount he has after 2nd proposition = (2x - 10) + (2x - 10) - 10 = 4x - 30
He repeats this procedure, now with $4x-30 in his pocket...but this time he is left with zero dollars...
r = amount he has after 3rd proposition = (4x-30) + (4x-30) - 10 = 8x-70 = 0
8x - 70 = 0,
x = $8.75

A store is randomly giving away gift cards to the first 150 customers. They are giving 130 gift cards that have a value of $5 each and 15 gift cards that have a value of $50 each. The rest of the gift cards have a value of $100 each. Which is the probability that a customer will get a $100 gift card?
Answer:
1/30
Step-by-step explanation:
The total number of cards is 150. Subtract the numbers of the other values, 130 and 15 to get the number of $100 cards.
150 -145 = 5
5/150 is the number out of the total.
Simplify to get the probability: 1/30
