B. 45
C. 27
D. -27​

Answers

Answer 1

Answer:

B. 45

Step-by-step explanation:

-3 + c/3 = 12

c/3 = 12+3

c/3 = 15

c = 15×3

c = 45

Answer 2

Answer:

45

Step-by-step explanation:

-3 + c/3 = 12

c/3 = 12 + 3

c/3 = 15

c : 3 = 15

c = 15 . 3

c = 45

Step-by-step explanation:

multiply 3/4 by 4 and youll get 3 and them multiple 84 by 4 and you'll get 336. Divide 336 by 3 and youll get your answer.

How can you use factoring to solve quadratic equations in standard form?

Answers

Step-by-step explanation:

The roots or the zeroes of a quadratic equation are its x-intercepts, which are the points on the graph where it crosses the x-axis. When a quadratic equation is in standard form, ax² + bx + c, the usual goal is to find the binomial factors that could help us determine the roots or solutions to the given equation.  Once you find the factors, then you will use the Zero-Product Property to solve for the solutions.  

For example, if you were given the following quadratic equation in standard form, x² + 6x + 8 = 0, and were tasked to find its factors.

x² + 6x + 8 = 0

where a = 1, b = 6, and c = 8:

In order to find the factors of the given quadratic equation, we must find the  factors with a product ac, and sum b.  

Using 2 and 4 as possible factors produce a product that is equal to

product of ac:   2 × 4 = 8

sum of b:           2 + 4 = 6.

Therefore, the factors of the given quadratic equation, x² + 6x + 8 = 0 are:

(x + 2) (x + 4).

Using the Zero-Product Property, where it states that for any real numbers, u and v, if uv = 0, then u = 0 or v = 0.  

Thus, setting the binomial factors of the given quadratic equation to zero will provide the solutions.

(x + 2) (x + 4)

x + 2 = 0

x + 2 - 2 = 0 - 2

x = -2

x + 4 = 0

x + 4 - 4 = 0 - 4

x = -4

Therefore, the solutions to the quadratic equation, x² + 6x + 8 = 0 are x = -2, and x = -4.

In kick boxing, the force needed to break a board varies inversely with the length of the board.If it takes 5 pounds of pressure to break a board 2 feet long, how many pounds of pressure will it take to break a board that is 8feet long?

Answers

Answer:

Step-by-step explanation:

By taking k as constant:

P = k/L (where P is pressure, and L is length)

5 = k/2

k = 10

Therefore:

P = 10 / L

P = 10/ 8

P = 1.25 Pounds.

ABCD is a parallelogram and X and Y are any point on CD and AD respectively. Prove that triangle AXB and triangle BYC are equal in area. Prove that​

Answers

Answer:

See answer below

Step-by-step explanation:

ABCD is a parallelogram                     Given

BC ≅ AD; AB ≅ DC                             opposite sides of a parallelogram ≅

Δ AXB = 1/2 (AB)(AD)                           Formula for the area of a Δ

Δ BYC = 1/2 (BC) (DC)                           Formula for the area of a Δ

1/2 (AB)(AD)= 1/2(BC)(DC)                      Substitution

∴ Area of Δ AXB = Area of ΔBYC

Write the equation of the line with x-intercept 3 and passing through the point (5.4)

Answers

Answer: y=(1/5)m+3

Step-by-step explanation:

Start with the standard form of an equation of a straight line:  y=mx+b, whre m is the slope and b the y-intercept (the value of y when x=0).

y=mx+b

We know b (3), so:

y=mx + 3

To find the slope, m, we can use the one given point, (5,4):

y=mx + 3 for (5,4) would be:

4 = m*5+3

1 = 5m

m = (1/5)

y=(1/5)m+3

Answers

Answer:

Each one of the ten people has to shake hands with all the $20$ other people they don’t know. So $10\cdot20 = 200$. From there, we calculate how many handshakes occurred between the people who don’t know each other. This is simply counting how many ways to choose two people to shake hands from $10$, or $\binom{10}{2} = 45$. Thus the answer is $200 + 45 = \boxed{\textbf{(B)}\ 245}$.

How many gallons of a 50​% antifreeze solution must be mixed with 90 gallons of 25​% antifreeze to get a mixture that is 40​% ​antifreeze? Use the​ six-step method.

Answers

Let x be the needed volume of 50% antifreeze solution. x gallons of this solution contains 0.50x gal of antifreeze.

Mixing this amount with 90 gal of 25% solution makes a total volume of (x + 90) gal of solution.

90 gal of 25% solution contains 0.25 (90 gal) = 22.5 gal of antifreeze.

The new mixture would then consist of (0.50x + 22.5) gal.

If its concentration of antifreeze is supposed to be 40%, then

(0.50x + 22.5)/(x + 90) = 0.40

Solve for x :

0.50x + 22.5 = 0.49 (x + 90)

0.50x + 22.5 = 0.49x + 44.1

0.01x = 21.6

x = 2160

Answers

Answer:

900 km5400 km

Step-by-step explanation:

The speed of sound in water:

s = 1500 m/sec

Time:

t = 10 min = 10*60 sec = 600 sec

or

t = 1 hour = 60 min = 60*60 sec = 3600 sec

Distance in 10 min:

d = s*td = 1500 *600 = 900 000 m = 900 km

Distance in 1 hour:

d = 1500*3600 = 5 400 000 m = 5400 km
