Geometry help please.

Answer:

z=(-3/2, -1/2) (Or z=(-1.5,-0.5) if they want decimals instead of fractions)

Step-by-step explanation:

7z²+8z+3-3z²=0

4z²+8z+3=0

(2z+3)(2z+1)=0

z=(-3/2, -1/2) (Or z=(-1.5,-0.5) if they want decimals instead of fractions)

Answer:

Step-by-step explanation:

7z^2 + 8z + 3 = 3z^2

4z^2 + 8z + 3 = 0

(2z + 3)(2z + 1) = 0

2z + 3 = 0

z = -3/2

2z + 1 = 0

z = -1/2

Complete question :

Calculate the weighted mean price of a table from the following

data, assuming that weights are proportional to the number of

tables sold.

36.00

40.00

44.00

48.00

Price

per

table (Rs.)

No. of tables sold

14

11

9

6​

Answer:

40.7

Step-by-step explanation:

The weighted mean:

Since weights are proportional to the number of tables sold :

(14 + 11 + 9 + 6) = 40

Weights are :

14 /40 = 0.35

11/40 = 0.275

9/40 = 0.225

6/40 = 0.15

Weighted mean = Σweight * price per table

(0.35*36) + (0.275 * 40) + (0.225 * 44) + (0.15 * 48) = 40.7

Answer:

The area of this trapezoid is equal to 660[tex]in^{2}[/tex]

Step-by-step explanation:

The area of a trapezoid is equal to the sum of the lengths of the two parallel sides times the height of the trapezoid and then divided by 2, so we can write that down as...

[tex]Area = \frac{(a+b)(h)}{2}= \frac{(30 + 36)(20)}{2} = \frac{1320}{2} = 660 in^{2}[/tex]

Therefore the area of this trapezoid is equal to 660[tex]in^{2}[/tex]

Answer:

C

Step-by-step explanation:

Answer:

Step-by-step explanation:

As we know that from a theorem,

A greater angle of a triangle is opposite a greater side. Let ABC be a triangle in which angle ABC is greater than angle BCA; then side AC is also greater than side AB. For if it is not greater, then AC is either equal to AB or less.

As we have  angle A =120 so it means the other 2 angles will be less than angle A , hence the opposite side to angle A is BC ,

Hence BC line is the longest line in triangle ABC

Case : BC is the longest side

#Remember that the total degree of triangle is 180°

#If A° = 120° so B° + C° = 180°-120°

B° + C° = 60°

#From here, you already know that even the total of both of B and C is less than 120° which is the degree of A.

#If you are gonna find the length of BC, then you need to use trigonometry which will be

BC/sinA = AB/sinB = AC/sinC

#so, from here you can know that BC will be the longest one, because bigger the value, in sin, will be smaller the value

Answer:

I don't know what the question is but if you are asking for the intersection of the 2 lines it is no solutions, these 2 lines are parallel due to having the same slope, which means they will never intersect.

Answer:

77 degrees

Step-by-step explanation:

The interior angles of a triangle always add up to 180 degrees, so you can form an equation:

[tex]x + 71 + 32 = 180[/tex]

[tex]x + 103 = 180\\x = 77[/tex]

Answer:

8.5

Step-by-step explanation:

The required value of the number is 8.5 which is twice the difference between a number and 5 is 7​.

To solve this problem, we first need to express the given information in terms of a mathematical equation.

The statement "Twice the difference of a number and 5 is 7" can be represented as the equation 2 × (x - 5) = 7, where x is the number we're trying to find.

Next, we can solve this equation to find the value of x. To do this, we can first distribute the 2 on the left-hand side of the equation to get 2x - 10 = 7.

Then, we can add 10 to both sides of the equation to get 2x = 17.

Finally, we can divide both sides of the equation by 2 to get x = 17/2 = 8.5.

Therefore, the required value of the number is 8.5.

Answer:

$12.78.

Step-by-step explanation:

To determine the expected price of a good in 2000, knowing that in 2015 it cost $ 17.6 and that the consumer price indexes were worth 172.2 in 2000 and 237.017 in 2015, the following calculation must be performed:

237.037 = 17.6

172.2 = X

X = 172.2 x 17.6 / 237.037

X = 3,030.72 / 237.037

X = 12.78

Thus, the expected price of the good in the year 2000 is $ 12.78.

Answer:

Step-by-step explanation:

Given the inequality expression -2/3p - 4/3 > 1/5 p

Collect like terms;

-2/3 p - 1/5 p > 4/3

Find the LCM

(-10-3/15) p > 4/3

-13/15p > 4/3

Cross multiply

-13p * 3 > 15 * 4

-39p > 60

p < -60/39

p < -20/13

Hence the required result is p < -20/13
