ABCD is a square with an area of 49 cm2, and BE = 4.95 cm. Point E is the midpoint of 2 diagonal lines crossed inside the square.
Answer:
I suppose we want to find the side length of the square.
We know that:
The area of the square is 49cm^2
The distance between one of the vertices of the square and the middle of the square is:
BE = 4.95cm
Now let's remember some things.
For a square of side length L, the area is:
A = L^2
and the diagonal length is:
D = √(2)*L
In this case, we know that half of the diagonal is equal to:
BE = 4.95 cm
Then the diagonal is:
D = 2*BE = 2*4.95cm = 9.9cm
And for the diagonal formula, we have:
D = 9.9cm = √(2)*L
Then the side length is:
L = 9.9cm/√(2) = 7cm
And if we check the area of this square, is:
A = L^2 = (7cm)^2 = 49cm^2
So it checks.
Then we can conclude that the sidelength of the square is 7cm, which means that:
AB = 7cm
BC = 7cm
CD = 7cm
DA = 7cm

Will their money double within 10 years?
Will their money double within 15 years?
Answer:
A= P(1+r/n)^nt

Can someone help with this too
Step-by-step explanation:
13x - 26 °+ 5x +8° = 180° ( being co- interior angle)
13x + 5x - 26 °+ 8° = 180°
18x - 18 = 180°
18x = 180°- 18°
18x = 162°
x= 162° ÷ 18
x= 9°

What is the length of the hypotenuse of the triangle when x=15?
Answer:
114.24°
Step-by-step explanation:
7(15)+6= 105
3(15)= 45, now we plug it in the formula, [tex]a^{2}+b^{2}=c^{2}[/tex]
[tex]105^{2}+45^{2} = 13050[/tex]
so now we square root it
[tex]\sqrt{13050}[/tex]= 114.24
Step-by-step explanation:
111^2 + 45^2 = 14346
then take the square root of 14346
which is 119.77
You and your friend decide to go to Red Robin to eat. You are both part of the rewards club and receive coupons in the mail. You have a coupon a coupon for 10% off the total bill. Your friend has a coupon for $5 off the total bill. Which coupon should you use to save the most money if the total bill was $29.90? *
A. the $5 off coupon
B. the 10% off coupon
C. either one
D. cannot be determined
Answer:
A. the $5 off coupon
Step-by-step explanation:
10% off would only be 2.99 off the bill making it 26.91 but the $5 would take off more
The coupon I would use to save the most amount of money on the total bill is my friend's coupon worth $5.
Which coupon should I use?Coupons reduce the price of an item. An item becomes cheaper after a coupon has been used. In order to determine the better coupon, calculate the price after each coupon has been used.
Coupon 1 : 10% x 29.9 = $3
Coupon 2 : 29.90 - $5 = $24.90

Step-by-step explanation:
Right to Left
Number of 6th graders that are very unhappy is 14
Number of 6th graders that are happy is 13
Number of 7th graders that are neutral is 12
Number of 7th graders that are happy is 30
Total number of 7th graders is 80
Number of 8th graders that are very unhappy is 20
Number of 8th graders that are very happy is 2
Number of unhappy students is 59
Number of very happy students is 25
What are the missing values?Total number of 7th graders = 196 - 50 - 66 = 80
The number of 7th graders that are neutral = 31 - 10 - 9 = 12
The number of 6th graders that are happy = 80 - 13 - 22 - 3 - 12 = 30
The number of 6th graders that are happy = 44 - 1 - 30 = 13
The number of 6th graders that are very unhappy = 66 - 10 - 10 - 19 - 13 = 14.
The number of 8th graders that are very unhappy = 37 - 3 - 14 = 20
Total number of unhappy students = 19 + 22 + 18 = 59

the average of 5 numbers is 7. when one more number is added the average becomes 10. what number was added?
Answer:
13
Step-by-step explanation:
for example, Sum of 5 no. = 7×5=35
Sum of 8 no. = 8.5×8=68
Sum of added all three no. = 68 - 35 = 33
average of three new numbers = 33/3=11
The number 25 is added then the average becomes 10.
What is an average?The average is defined as the ratio of the sum of the data to the total numbers of the data.
Average = ( Sum of the numbers ) / ( number of the data )
Given that the average of 5 numbers is 7. when one more number is added the average becomes 10.
The number added is calculated as:-
Sum of the numbers = 5 x 7 = 35
Let x is the number added.
Sum of the numbers = 35 + x
We know that some of the numbers = 10 x 6
35 + x = 10 x 6
35 + x = 60
x = 60 - 35
x = 25
Hence, the number added is 25.

Calculate the distance between the points E=(-6,8) and N=(-1,5) in the coordinate plane. Give an exact answer (not a decimal approximation).
Answer:
6 units
Step-by-step explanation:
The formula for calculating the distance between two points is expressed as;
[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Given the coordinate points E=(-6,8) and N=(-1,5)
[tex]EN = \sqrt{(5-8)^2+(-1+6)^2}\\EN = \sqrt{(-3)^2+(5)^2}\\EN = \sqrt{9+25}\\EN = \sqrt{34}\\EN = 5.8\\EN \approx 6[/tex]
Hence the distance between the points is approximately 6 units

Answer:
240 cm^3
Step-by-step explanation:
The solid is composed by two rectangular parallelepipeds. To find the total volume we have to find the volume of the two solids and added up.
To find the volume of a parallelepiped we have to use this formula:
V = base surface x height
The area of rectangle is : base x width
So:
Area first rectangle: 4 x 6 = 24 cm^2
V = 24 x 7 = 168 cm^3
Area second rectangle: 4 x 2 = 8 cm^2
V = 8 x 9 = 72 cm^3
total volume = 168 + 72 = 240 cm^3

Each color is a
different digit
eren
Answer:
The number printed in red color = 5
The number printed in silver color = 8
The number printed in blue color = 1
Step-by-step explanation:
P.S - The exact question -
Given - The diagram
To find - The number that represent Red, Silver and Blue color.
Proof -
Let the number printed in red color = r
Let the number printed in silver color = s
Let the number printed in blue color = b
Also,
Given that the equation is -
b s r
b s r
+ b s r
= r r r
Now,
We have to think of a number that if we add the last digit of the number gives the same last digit.
Bt inspection ,
the number would be 5
Because 5 + 5 + 5 = 15
Lat place of the equation is same
So,
The number printed on red color = 5
⇒r = 5
So, the equation becomes
b s 5
b s 5
+ b s 5
= 5 5 5
Now,
We have to think of a number whose last digit add up to 3 + 1 gives the last digit number 5 ( we add 1 because by adding 5 + 5 + 5 , we get 15 so we write the last digit 5 and 1 goes to the remainder and that remainder 1 will add up in the next number addition)(addition rule)
i.e.
s + s + s + 1 = number whose end digit is 5
By inspection,
The number would be 8
because 8 + 8 + 8 + 1 = 25
So,
we get
s = 8
So, the equation becomes
b 8 5
b 8 5
+ b 8 5
= 5 5 5
Now,
By same process , we will find the number of blue color
By inspection the number on blue color = 1
∴ we get
The number printed in red color = 5
The number printed in silver color = 8
The number printed in blue color = 1
and the equation is -
1 8 5
1 8 5
+ 1 8 5
= 5 5 5
