Rebecca's window store made a mosaic for the community center. The mosaic had a 7 × 7 array of different color square tiles. If each tile is 3 1/2 ft long, what is the area of the whole mosaic?
Answer:
600 1/4 ft²
Step-by-step explanation:
Window is a 7 * 7 square array
Length per tile = 3 1/2 ft long
Dimension of entire array :
3 1/2 * 7 by 3 1/2 * 7
7/2 * 7 by 7/2 * 7
49/2 by 49/2
Recall : Area of a square = a² ; where a = side length
Area of entire array :
49/2 * 49/2 = 2401 / 4 = 600 1/4 ft²

Which expression(s) have the same value of the question on the picture?
Answer:
Options A, Option C and Option D
Step-by-step explanation:
[tex](\frac{2}{5})^2=(\frac{2}{5})^{1+1}[/tex]
= [tex](\frac{2}{5})(\frac{2}{5})[/tex]
= [tex]\frac{2\times 2}{5\times 5}[/tex]
= [tex]\frac{2^2}{5^2}[/tex]
= [tex]\frac{4}{5^2}[/tex]
= [tex]\frac{4}{25}[/tex]
Therefore, Options A, Option C and Option D are the correct options.

Remark
The two angles share the same side of vertically opposite angles. That makes them supplementary which means the two angles add to 180 degrees.
Equation
4x + 8x + 12 = 180 Combine like terms on the left
Solution
12x + 12 = 180 Subtract 12 from both sides12x = 180 - 12 Combine12x = 168 Divide by 12x = 168/12x = 142/5 kilogram of soil fill 1/3 of a container. Can 1 kilogram of soil fit in the container?
Answer:
Yes
Step-by-step explanation:
Answer:
Yes
Step-by-step explanation:
2/5 kilogram od soil = 1/3 of the container
So 2/5 + 2/5+ 1/5 = 1 kilo gram of soil
so 1 kilo will fit into the container

Sue has $74,210 in a savings account. The interest rate is 15% per year and is not compounded. How much will she have in 2 years? Use the formula i = prt, where i is the interest earned, p is the principal (starting amount), is the interest rate expressed as a decimal, and t is the time in years.
Answer:
$22,263
Step-by-step explanation:
15% of $74,210 is $11,131.50 so $11,131.50 X 2= $22,263
so after 2 years the total amount of money along with interest will be a total of = $96,473

From 1 second to 3 seconds Denise had stopped
We can tell that this is true because looking at the graph we can see that from 1 to 3 seconds the distance stayed the same which indicates that Denise was not walking
Answer:
I think it is B between 1 and 3 bc a flat line shows no progress and the only area where is show a flat line is between 1 and 3 so he stopped walking at that point

Talia bas 26 $1 coins, 20-cent coins, 50-cent coins. The number of $1 coins is 6 more than the number of 20-cent coins. The total value of the coins is $17.20. How many 50-cent coins are there?
Answer:
8 fifty cents coin.
Step-by-step explanation:
Let's assign variable for the unknown number of coins.
Let there are 'x' number of $1 coins
'y' number of 20 cent coins
'z' number of 50 cent coints.
Totally there are 26 coins.
So, x+y+z=26
Now, there are 6 more $1 coins than 20-cent coins.
We can set up equation for this as
x= y+6
Now, total value of these coins is $17.20
We can setup equation as
100 x+20 y+50 z=1720
Now, substitute x as y+6
100(y+6) +20 y+50 z =1720
Distribute the 100 to get rid ( )
100 y+600 +20 y+50 z=1720
Combine like terms
120 y+50 z= 1120
Keep this equation as it is.
Plug in x as y+6 into x+y+z=26
y+6+y+z=26
2y+z=20
Now, take the two equations
2y+z=20
120y+50z=1120
Multiply first equation by -60 to eliminate the y terms when we add them.
-120y-60z=-1200
120y+50z= 1120
-------------------------
-10z =-80
Divide both sides by -10
z=8
Now, plug in z as 8 into 2y+z=20
2y+8 =20
Subtract both sides 8
2y=12
Divide both sides by 2
y=6
Now, plug in y, z values into the first equation.
x+6+8=26
x+14=26
Subtract both sides 14
x=12
So, there are eight 50-cent coins.
determine the total surface area.
Answer:
15 x 8 x 11 x 17 = 22440

Andrea has 5 bags with 2 marbles in each bag. Kori has 3
bags with 2 marbles in each bag.
How many more marbles does Andrea have?
Answer:
4 more marbles
Step-by-step explanation:
Andrea in total, has 10 marbles since 5*2 is 10
Kori in total, has 6 marbles since 3*2 is 6
Subtract 10 by 6 is 4
10-6=4
4 marbles
A parallelogram has vertex at (-5 , -1) (-2, -1), (-3,-4), and (-6,-4). What is the approximate perimeter of the parallelogram round your answer to the nearest hundredth
Answer:
12.4 units
Step-by-step explanation:
We have to find the length of the sides of the parallelogram which is calculated using the formula for Distance
= √(x2 - x1)² + (y2 - y1)² where we are given the vertices (x1, y1) and (x2, y2)
For side A
(-5 , -1) (-2, -1)
= √(-2 -(-5))² + (-1 - (-1))²
= √(-2 + 5)² + (-1 + 1)²
= √3² + 0
= √9
= 3 units
For side B
(-2, -1), (-3,-4)
= √(-3 -(-2))² + (-4 -(-1))²
= √(-3 + 2)²+ (-4 + 1)²
= √-1² + -3²
= √1 + 9
= √10 units
= 3.1622776602 units
Approximately = 3.2 units
For side C
(-3,-4), (-6,-4).
= √(-6 -(-3))² + (-4 - (-4))²
= √(-6 + 3)² + (-4 + 4)²
= √-3² + 0²
= √9
= 3 units
For side D
(-5 , -1), (-6,-4)
= √(-6 - (-5))² + (-4 - (-1))²
= √(-6 + 5)² + (-4 + 1)²
= √-1² + -3²
= √1 + 9
= √10 units
= 3.1622776602 units
Approximately = 3.2 units
From the above calculation , we can see that,
side A = side C
side B = side D
The formula for the Perimeter of a Parallelogram is = 2(Side a + Side b)
= 2(3 + 3.2) units
= 2(6.2) units
= 12.4 units
what is the scale factor
Answer:
multiply 5 times 12 then divide by 2 which equals 30 then 15 times 36 divided by 2
