Alanna is painting a border along the top of a wall. the border consists of kite-shaped figures as shown. 3 kites are connected at 1 point. each kite measures 6 inches across and 12 inches long. the wall is 12 feet across. how many square inches of the wall will be covered with kites? 216 432 864 1,728
If each kite measures 6 inches across and 12 inches long. The square inches of the wall will be: 864 square inches.
Square inches of the wal
Diagonals= d1 and d2
First step
Area =(1/2)×(d1×d2)
Area=(1/2)×(6×12)
Area =36 in²
Second step
1 feet = 12 inches
12 feet = 12×12
12 feet = 144 in
Third step
Number of square inches=(144/6)×36
Number of square inches=24×36
Number of square inches= 864 square inches
Therefore the square inches of the wall will be: 864 square inches.

7 * as much as the sum of1/3+ 4/5
Answer:
First you add 1/3 and 4/5
To add 2 fractions, they need to have the same denominator. Since 3 and 5 don't have a common factor, so you multiply 1/3 by 5, and 4/5 by 3, so you get: 5/15 +12/15
Now, the two fractions got the same denominator, and you can add them by adding the numerators over the same denominator. (You don't add denominators in addition) so you get:
5+12/15 which is 17/15
That's the sum of 1/3 + 4/5.
Now, they want the sum of the 2 fractions 7 times. So you multiply 17/15 by 7. And as you know, 7 = 7/1. So you get:
In multiplication no need to have the same denominator. You multiply nominators by nominators and denominators by denominators. So you get:
17*7/15*1 and you get 119/5
Since 119 and 15 don't have a common factor, so they can't be simplified.
So, the answer is 119/15.

Find the distance between the pair of points. Round
your answer to the nearest tenth, if
necessary. (4, 11), (- 9, 8)
Answer:
13. 3
Step-by-step explanation:
Given Points:
(x1= 4, y1 = 11), (x2= - 9, y2 = 8)
Distance Formula:
d² = (x2 -x1)² + (y2 -y1)²
Substitute and Calculate:
d² = ( -9 -4)² + ( 8 -11)²
d² = (-13)² + (-3)²
d = √(169+9)
d = √178
d = 13.34166406 round to the nearest tenth
d = 13. 3
is 63/20 equivalent to 4/9 divided by 5/7
Answer:
No
Step-by-step explanation:
4/9 divided by 5/7 is equal to 4/9 * 7/5 = 28/45. We can see that 63/20 is not equivalent to 28/45 as 28/45 is less than one and 63/20 is greater than one.

Answer:
The mean is 80.875 or 81 rounded
Step-by-step explanation:
To find the mean of any set of numbers, you need to get the values added up together and the #values (how much numbers there are).
Formula setup: amountaddedup/#numbers
✔ When we plug in the values in the formula, you will get 80.875.
The mean of the given data is 80.75.
What is Statistics?Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
The given data is 95, 45, 37,82 ,90,100, 91 ,78 , 67 ,84 ,85 ,85 , 82 , 91 , 93 , 92,76, 84, 100, 59 , 92, 77 , 68 and 88
Mean = Sum of the observations/ Total number of observation.
Sum of the observations = 95+ 45+37+82+90+100+91+78+67+84+85+85 +82 +91+93+92+76+84+100+59+92+77+68+88

What is the value of y in the relative frequency table? round the answer to the nearest percent. 12% 27% 46% 52%
The relative frequency table is a two way table, and the value of y in the relative frequency table is 27%
How to determine the value of y?From the complete question, we have the following row
y 24% 51%
Express the row as an equation
y + 24% = 51%
Subtract 24% from both sides
y + 24% - 24%= 51% - 24%
Evaluate the difference
y = 27%
Hence, the value of y in the relative frequency table is 27%

A rectangle is 4 times as long as it is wide. If the area of the rectangle is 1600cm^2, what are the dimensions?
Answer:
dimensions 20cm x80cm
Step-by-step explanation:
length is 4W of 1W,
LxW=area of 1600
4W x 1W = 1600cm2
divide both by 4 to isolate W
W=400cm2
square root of 400=20
replace W with 20 into equation 4Wx1W
4x20=80
1x20=20
80 is 4x the width of 20
