The length of the diagonal is 24 inches
From the given diagram, the length of the diagonal is twice the length EA
Mathematically;
EH = 2EA
Given the parameter:
EA = 12in
EH = 2(12)
EH = 24 in
Hence the length of the diagonal is 24 inches

n order to better manage his money, Joe kept track of his monthly grocery bills for the past six months to see how much he had spent. These amounts appear in the table.
Round each number in the table to the nearest hundred and estimate the total amount of money Joe should budget for groceries for the next 6 months.
Answer:
1,100
Step-by-step explanation:
200 + 200 + 200 + 200 + 100 + 200
Total amount after rounding off will be : 900
What is Rounding of numbers to nearest hundred ?
Rounding off a number to the nearest hundred means that you have to look or find the hundred which is closest to the given number and then write that as the rounded-off number .
Rounding off each number in the table to the nearest hundred :
1) 223 ( since , we have 223 and 223 < 250 . Since, 223 is closest to 200 as compared to 300 , after rounding it off we will get 200 instead of choosing 300) = 200
2) 189 =200
3) 210 = 200
4) 164 = 200
5) 148 = 100
6) 206 = 200
Total amount after rounding of numbers will be = 200 + 200 + 200 + 100 + 200
= 900

The points A,B and C have coordinates (2,1), (b,3) and (5,5), where b>5 and angle ABC = 90 degrees. Find b.
Answer:
b=6
Step-by-step explanation:
modul of the vector AB= sqrt((b-2)^2+(3-1)^2)= sqrt (b^2-4b+8). It is the length of the side AB
modul of the vector BC is equal to sqrt ((b-5)^2+(-2)^2)= sqrt (b^2-10b+29)
modul of the vector AC is sqrt ((5-2)^2+(5-1)^2)= 5
squared modul of AB + squared modul of BC = squared modul of the vector AC.
b^2-4b+8+b^2-10b+29=25
2b^2-14b+12=0
b^2-7b+6=0
b=1 b=6
b>5, s0 b=6
the length of rectangular ground is 18m longer than its breadth and its perimeter is 124 find its length and breadth
Answer: length is 22m and breadth is 40m.
Step-by-step explanation:
breadth = b
length = 18+b
so
perimeter of rectangle = 2(l+b)
124 = 2(18+b+b)
or, 124 = 36 + 4b
or, 124-36 = 4b
or, b = 88/4 = 22m
so
l = 18 + b
= 18+22
= 40m
Are a total of 127 Cars And trucks on a lot. If there. For more than twice the number of trucks, then cars, how many cars and trucks are on the lot?
Answer:
41 cars and 86 trucks
Step-by-step explanation:
C+T=127
2C+4=T
C+(2C+4)=127
3C+4=127
3C=123
C=41When C=41,
41+T=127
T=127-41
T=86

Can Someone help me!
Answer:50 degree
Step-by-step explanation:
It is an isosceles triangle so two sides and angles are equal. The first line is facing the first angle so the second angle ( m<DEF) = 65 degrees because both angles are equal.
This implies that m<FED =
65 + 65+ <FED= 180( sum of angle in a triangle)
130 + <FED=180
<FED= 180- 130
<FED= 50 degree

Select all solutions to the equation (2x — 4)(x + 5) = 0.
x = -1/2
x = 1/2
x = -2
x = 2
x = -5
x = 5
Answer:
(2x-4) (x+5)=0
2x(x+5) -4(x+5)=0
2x^2+10x-4x-20=0
2x^2+6x-20=0
x^2+3x-10=0 ( Taking common of 2 )
x^2+(5-2)x-10=0 • (3=(5-2)x)
x^2+5x-2x-10=0
x(x+5)-2(x-5) =0 • Taking common
(x+5)(x-2) =0
so x=-5 or x=2.
The solutions to the equation (2x — 4)(x + 5) = 0 will be negative 5 and 2. Then the correct options are D and E.
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 equation is given below.
(2x - 4)(x + 5) = 0
The factors (2x - 4) and (x + 5) will be zero. Then we have
2x - 4 = 0
2x = 4
x = 4/2
x = 2
Then the other solution to the equation will be
x + 5 = 0
x = -5
The solutions to the equation (2x — 4)(x + 5) = 0 will be negative 5 and 2. Then the correct options are D and E.

solve 4m plus 2n equals 5n for m.
Answer:
m = (3/4) n
Step-by-step explanation:
4m + 2n = 5n
The subtraction property of equality states that we can subtract 2n from both sides to isolate the m and its coefficient to get
4m = 3n
The division property of equality states that we can divide 4 from both sides to isolate only the m (we divide by 4 because anything divided by itself equals 1) to get
m = (3/4) n
