B. (6.9) + 3. (5 + 1)


C.3.1 +3.5+ 9.6


D. (3 + 1). (3 + 5) + (69)

Answer:

1,100

Step-by-step explanation:

200 + 200 + 200 + 200 + 100 + 200

Total amount after rounding off will be : 900

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

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

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

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

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.

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.

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
