Answer:

the distance from the floor below to the top of the bookcase

Step-by-step explanation:

From the question we are given the following

distance from a stage to the floor below = -3

distance from the stage to the top of a bookcase = 3

The distance from the floor below to the top of the bookcase = distance from a stage to the floor below + distance from the stage to the top of a bookcase

The distance from the floor below to the top of the bookcase = -3 + 3

The distance from the floor below to the top of the bookcase = 0

Hence zero represents the distance from the floor below to the top of the bookcase

Answer:

Assuming that the x2 is x squared, B

Step-by-step explanation:

(1)(1) + 5(1) - 6 = 1 + 5 - 6 = 6 - 6 = 0

(-6)(-6) + 5(-6) - 6 = 36 - 30 - 6 = 6 - 6 = 0

Answer:

B

Step-by-step explanation:

Let's solve using factoring.

x²+5x-6=0

5 is the sum of the numbers, while -6 is their product.

Think: which two numbers add up to 5, but when multiplied, equal -6?

Those numbers are -1 and 6.

Now factor the polynomial:

(x-1)(x+6)=0

split into parts:

(x-1)=0

x-1=0

x=1

(x+6)=0

x+6=0

x=-6

So B

Hope this helps!

Answer:

Answer:

Y=4X-5

Step-by-step explanation:

The Slope is a positive 4 so you will already have the equation Y=4X and the y-intercept is the Y when X is at the origin. Since the y-intercept is negative you have to subtract from the slope instead of adding. Then you get Y=4X-5.

Answer:

899 + 66 = 3*X, X being the wholesale price.

965 = 3*x -> x = 965/3 -> x = 321.66 (and 2/3 of a cent)

Step-by-step explanation:

Answer:

y = -1/5x + 2

Step-by-step explanation:

y = mx + b

m (slope) = -1/5

b (y-intercept) = 2

y = -1/5x + 2

Answer:

Total cost = 983.8

Step-by-step explanation:

Monthly charge = 39.95

One time set up fee = x

Number of months = y

Total cost = x + 39.95y

The total cost of 6 months of service is 264.70.

264.70 = x + 39.95(6)

264.70 = x + 239.7

264.70 - 239.7 = x

x = 25

Total cost = 25 + 39.95y

Write and solve a linear equation to find the total cost for 2 years of service

2 years = 24 months

Total cost = 25 + 39.95y

= 25 + 39.95(24)

= 25 + 958.8

= 983.8

Total cost = 983.8

Answer: Neighborhood Bank - 0.65% interest, compounded weekly

Step-by-step explanation:

The bank she would suggest Gail pick if she plans to have her money in the account for 15 years is Neighborhood Bank - 0.65% interest, compounded weekly.

If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:

[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]

Given that Gail has $5,500 that she wants to put in a new savings account.

Neighborhood Bank - 0.65% interest, compounded weekly

Beautiful Day Bank - 0.65% interest, compounded daily

Thus, $5,500 x 0.65% = $35.75

$35.75 a day times 360 days = $12870

$12870 times 20 = $257,400.

$257,400 times 20 = $514800 (16.2mil)

Hence, The bank she would suggest Gail pick if she plans to have her money in the account for 15 years is Neighborhood Bank - 0.65% interest, compounded weekly.

There are 3 numbers on the cube greater than 3 ( 4, 5, & 6)

This means he has a 3/6 = 1/2 chance of doing that.

He has a 1/2 chance of getting tails on the coin.

The probability of doing both would be the probability of the cube roll x the probability of the coin toss:

1/2 x 1/2= 1/4

The answer is 1/4

Answer:

Step-by-step explanation:

1. Eggs are sold at a price of P 105.00 per dozen.

Rate = [tex]\frac{1}{105}[/tex]

2. The carpentry job can be done by 3 carpenters in 4 days.

Rate at which each carpenter works = [tex]\frac{4}{3}[/tex] = 1[tex]\frac{1}{3}[/tex] days

This shows that each carpenter worked for an average of 1.3333 days to complete the job.

3. Five tickets are sold at P 600.00

The price for one ticket = [tex]\frac{600}{5}[/tex]

                                       = 120

One ticket is sold for P 120.00.

4. The dollar's rate is P 52.00.

This implies that;

1 dollar = P 52.00

dollar rate = [tex]\frac{1}{52}[/tex]

5. The ratio of water to milk in the recipe is 1 to 4.

This implies that to 1 measure of water, 4 measures of milk is used in the recipe.

rate = [tex]\frac{1}{4}[/tex]

Answer:

Yes, 4 is the constant of proportionality

Step-by-step explanation:

The constant of proportionality here is the value you multiply x by to get y. if you divide 12/3, 24/6, 36/9, 60/15, the answer to all of those is 4. Because the multiplier is the same for each one they are all proportional.

Answer:

c  =  125  f

Step-by-step explanation:

Let´s call points  A ( home plate )  B (pitcher´s place ) and C ( outfielder place)

these three points form a triangle in which according to cosine law, one side of a triangle c  can be calculated by the equation:

c²  =  a²  +  b²  - 2a*b*cos∡a,b

a and  b are the other sides of the triangle and ∡a,b is the angle between sides a and b

All distances are in feet then the distance between  outfielder and pitcher  (c) is in feet:

c² = (43)²  +  ( 162)²  - 2*(43)*(162)*cos 27°            cos 27°  = 0,891

c²  = 1849 +  26244 - 12413,4

c²  =  15679,6

c = √15679,6

c  =  125  f

Answer:

See below

Step-by-step explanation:

Kites have perpendicular diagonals, two pairs of congruent angles and sides.

Required measures:

The angles are m∠1 =m∠2 =m∠3 =m∠4 = 90 degrees.

m∠9=m∠7 =m∠8= m∠10 = 53 degrees.

m∠5 = m∠6 =37 degrees

Let us find the angles.

m∠1 , m∠2, m∠3 and m∠4 are right angles.

m∠1 =m∠2 =m∠3 =m∠4 = 90 degrees.

Now let us find m∠9.

By angle sum property, the sum of three angles is 180 degrees.

m∠1 + 37 + m∠9 =180

37+90+m∠9=180

127+m∠9=180

m∠9=180-127

m∠9=53

m∠9=m∠7 = 53 degrees.

Now let us find m∠6.

53+90+m∠6=180

143+m∠6=180

m∠6=37 degrees.

m∠5 = 37 degrees as it is congruent to m∠6.

Now let us find m∠8.

m∠8 + 90+ 37=180

m∠8 +127=180

m∠8 =53 degrees.

m∠10 = 53 degrees.
