a photo collage consists of seven equal sized square photo arranged in a row to form a rectangle if the total area of the college is 567 square inches what is the length of the collage
Answers
Answer:
Step-by-step explanation:
I have attached a written explanation to help :).
Let's say each side of the square =[tex]x[/tex]
If we put 7 squares in a row to make the rectangle,
length of the rectangle = [tex]7x[/tex]
Area of a rectangle = length multiplied by width
Area of rectangle = [tex]7x[/tex] multiplied by [tex]x[/tex] = [tex]7x^2[/tex]
We are also told that the total area = 567
So [tex]7x^2 = 567[/tex]
Now solve for [tex]x[/tex].
Divide both sides by 7.
[tex]\frac{7x^2}{7} = \frac{567}{7}[/tex]
[tex]x^2 = 81[/tex]
Then square root both sides to find [tex]x[/tex]
[tex]x = \sqrt{81}[/tex] = 9
Finally, the question asks to find the length of the collage which we said was [tex]7x[/tex] and we know [tex]x = 9[/tex]
Length of collage = [tex]7x = 7[/tex] multiplied by [tex]9[/tex] = ?

NUMBER 4!!!!!!! if m∠JKP= 67°, find m∠NKO
Answers
Answer:
Step-by-step explanation:
I have some sympathy for the way the questions have been set up and numbered.
The givens are that the two lines that look like they are perpendicular, are perpendicular.
<JKP = 67 Given
<PKL = 180 - 67 < PKL is supplementary to <JKP
<PKL = 113
<PKM = 113 - 90 = 23
Here's what you want to know. <NKO = PKM because they are vertically opposite angles.
Therefore NKO = 23 degrees.
JL is perpendicular to MN, then
m ∠NKO= 23°
Given :
JL is perpendicular to MN and the m∠JKP= 67°
we need to find out m∠NKO
we know that JL is perpendicular to MN. so, <JKN makes an right angle .
m ∠JKN = 90°
PO is a straight line . It makes an angle 180 degree
m ∠JKP +m ∠JKN +m ∠NKO =180
[tex]67+90+m<NKO=180\\m<NKO=180-90-67\\m<NKO=23[/tex]
m ∠NKO= 23°

Franco begins to save for a new Lego set that costs $65. His parents gave him $35 towards the cost
and he plans to save $5 per week. Define all unknown variables. Write an equation modeling the total
amount he has saved.
Answers
Answer:
65-35=30
30 divided by 5 = 6
Step-by-step explanation:
First you have to subtract 65-35, which equals 30.
Then the problem says he plans to save 5 each week. That means he should get his lego set in 6 weeks, because 30 divided by 5 = 6
65-35=30
30 divided by 5 = 6

The sum of 3 consecutive odd integers is 36. Whal
consecutive odd integers
Answers
[tex]\huge\pink{Answer}[/tex]
Any odd number can be represented with 2n+1 where n is a whole number. Also, since the next consecutive number will be even (2n+1+1), then the next consecutive odd number must be 2n+1+2, or 2n+3. Since consecutive odd numbers are separated by 2, then the previous odd number should be 2n-1. So:
2n-1+2n+1+2n+3=366n+3=366n+3-3=36-36n/3=33/32n=11Now in order to find three odd consecutive numbers that will sum to 36, you must be able to divide 11 evenly by 2, and have a whole number as a result. This is impossible, so there aren't any 3 odd numbers that will sum to 36.

9: 1/36 chance of getting the same number on both dice
10: a) 5 b) 4/25
Explanation:
9: a die has 6 sides with each number. So the chance of getting a number on a dice once is 1/6. The second dice is the same with 1/6 chance. But to have them both be the same number means you have to multiply the probability. (1/6)/(1/6)=1/36
10:
a) 1/4 of the discs are blue, meaning you have multiply 1/4 by 20 which equals 5
b) the probability of getting a red is 12/20. So the probability of not getting red is 8/20. But both simultaneously, would mean for multiplying them. 8/20 •8/20=64/400 Then simplified to 4/50.

For his art project, Dorian is using square tiles of different sizes and colors to make a mosaic. The first three tiles are: 1. A = 5 cm2 2. A = 7 cm2 3. A = 9 cm2
which tile's side lengths will Dorian need to estimate?
Answers
Answer:
3cm²
Step-by-step explanation:
Since the sizes are square tiles, to know the tile's side lengths that Dorian need to estimate, we will use the formula for calculating the area of q square
Area of a square = L²
L is the side length of the tiles
For the tiles with area 7cm²
7 = L²
L² = 7
L = √7
L = 2.65cm
For tiles with area 5cm²
5 = L²
L² = 5
L = √5
L = 2.24cm
For tiles with area 9cm²
9 = L²
L² = 9
L = √9
L = 3.0cm
Since for all the square tiles the length of the tile is ≤ 3 cm, then the tile's side lengths that Dorian will need to estimate is approximately 3cm

(10x + 17)° = 87° + 5x° (This is because of the rule of corresponding angles)
=> 10x° = 87° + 5x° - 17°
=> (10x - 5x)° = 87° - 17°
=> 5x° = 70°
=> x° = ( 70/5 )°
=> x° = 14°
Therefore x = 14°
