Which of the following is not a true bi-conditional statement?

A.) It is noon if only if it is 12:00 PM
B.) An angle is right if and only if it’s measure is 90°.
C.) I am a violinist if and only if I am a musician.
D.) Two segments are congruent if and only if they have the same length.

Answers

Answer 1

well a bi conditional statement is a statement that joins P and Q together with ths use of if and only if eg P if and only if Q.

I think the answer is (A) because 12:00pm is not the only noon time. 1pm is also noon so yeah that's why I think its A

Selina walked 2 1/2 miles in 2/3 hour. Dennis 6 3/4 miles in 1 1/2 hours. Who walked faster and how much faster?

Answers

Answer:

Dennis walked faster by 0.75 miles/hr

Step-by-step explanation:

a)Selina's speed

speed= distance

                 time

          = 2.5 miles       =  3.75 miles/hr = the slower

               2/3 hrs

b) Dennis' speed

speed =  distance

                  time

           =  6.75 miles        = 4.5 miles/hr  = the faster    

                   1.5 hrs

difference in speed:

faster - slower

4.5 - 3.75

=0.75 miles/hr

Dennis walked 0.75 miles per hour faster than Selina's speed.

What is Average speed?

Average speed is defined as the ratio of the total distance traveled by a body to the total time taken for the body to reach its destination.

To determine Selina's speed

speed = distance/time

speed = 2.5 miles/(2/3) hour

speed = 3.75 miles/hour

To determine Dennis' speed

speed = distance/time

speed = 6.75 miles/(1.5) hour

speed = 4.5 miles/hour

Here Dennis' speed is greater than Selina's speed which means Dennis walked faster.

     

So the difference in speed = Dennis' speed - Selina's speed

The difference in speed = 4.5 miles/hour - 3.75 miles/hour

The difference in speed = 0.75 miles/hr

Thus, Dennis walked 0.75 miles per hour faster than Selina's speed.

You can paint 75 square feet of a surface every 45 minutes. Determine how long it takes you to paint a wall with the given dimensions.

9 ft x 9 ft

Answers

Answer:48.6

we know that

You can paint 75 square feet of a surface every 45 minutes

so

using proportion  

Find out how long it takes you to paint a surface area of 81 square feet

45(81)/75=48.6

hope this helped and I hope you get a correct answer :D

Answer:

48.6 minutes

Step-by-step explanation:

First we must identify the area of the given wall :

A = L * W

A = 9 * 9

81 = 9 * 9

[tex]81ft^2[/tex]

Now we know that we can paint 75 square feet every 45 minutes so we must use proportion to find out how long it'll take you.

[tex]\frac{75}{45} *\frac{ft^2}{min}[/tex]

=

[tex]\frac{81}{x}[/tex] [tex]\frac{ft^2}{min}[/tex]

x = 45(81) / 75

x = 3645 / 75

x = 48.6 minutes

Step 2:

11a = - 11         Combine Like Terms

Step 3:

a = - 11 ÷ 11       Divide

Answer:

a = - 1

Hope This Helps :)

The solution to the equation 6a + 5a = -11 is a = -1.

We have,

To solve the equation 6a + 5a = -11, we can combine the like terms on the left side of the equation and then isolate the variable a.

Step 1: Combine like terms

On the left side, we have 6a + 5a, which gives us 11a. The equation becomes:

11a = -11

Step 2: Isolate the variable

To isolate variable a, we divide both sides of the equation by 11:

(11a) / 11 = (-11) / 11

a = -1

Therefore,

The solution to the equation 6a + 5a = -11 is a = -1.

A passenger on a stranded lifeboat shoots two distress flares into the air. The first flare travels a maximum height 196 feet and lands in the water after 7 seconds. The height (feet) of the second flare above the water is given by f(t) = -16t(t-8), where t is time (seconds) since the flare was shot. Which flare travels higher? Which remains in the air longer?

Answers

Answer:

The second flare travels higher, 256 feet, and remains in the air longer, 8 seconds, than the first flare

Step-by-step explanation:

The given parameters are;

The height of the first flare = 196 feet

The duration the first flare spends in the air = 7 seconds

The function representing the height of the second flair is f(t) = -16t(t - 8)

Where;

t = The time since the passenger shot the second flare

The time the flair stays i the air is given by the time it takes for the height, f(t),  to be 0 as follows;

f(t) = 0 = -16t(t - 8)

-16t(t - 8) = 0

t = 0, or t = 8

The time the second flare stays in the air = 8 seconds

The maximum height reached by the second flair is given by the finding the maximum point of the curve of the function as follows;

d(f(t))/dt = 0 = d(-16t(t - 8))/dt = -32t + 128 at the maximum point (the coefficient of t² is negative in the quadratic equation)

-32t + 128 = 0

128 = 32t

32t = 128

t = 128/32 = 4

t = 4 at maximum height and f(4) = -16 × 4 × (4 - 8) = 256 feet

The maximum height reached by the second flare f(4) = -16 × 4 × (4 - 8) = 256 feet.

Therefore, the second flare travels higher, 256 feet, and remains in the air longer, 8 seconds, than the first flare, with maximum height of 196 feet, and time in the air of 7 seconds.

Answers

Answer: Yes. There's a proportional relationship

Step-by-step explanation:

We are told that Anthony and Miguel go to the store to purchase some new DVDs and that an advertisement in the window catches their attention as they saw that:

3 DVDs cost $22,50. This means the price of one will be:

= $22.50 / 3

= $7.50

5 DVDs cost $37.50. This means that the price for one will be:

= $37.50 / 5

= $7.50

Since the price of a DVD both cost $7.50, it means that the information on the sign represent a proportional relationship.

Boadu and Ansah formed a company and agreed that their annual profit will be shared in the ratio 4:5 respectively. If at the end of the year. Ansah received Gh€ 5.000.00 more than boadu how much was boadu shared?

Answers

Answer:

Step-by-step explanation:

The share of Boadu is Gh€ 222,222.22 if Boadu and Ansah formed a company and agreed that their annual profit will be shared in the ratio 4:5 respectively.

What is the ratio?

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

We have:

Boadu and Ansah formed a company and agreed that their annual profit will be shared in the ratio 4:5 respectively.

Let 4x be the share of Boadu and 5x be the share of Ansah

4x + 5x = 5,000,00

9x = 5,000,00

x = 55555.55

The share of Boadu = 4x = 4(55555.55) = 222,222.22

Thus, the share of Boadu is Gh€ 222,222.22 if Boadu and Ansah formed a company and agreed that their annual profit will be shared in the ratio 4:5 respectively.
