Answer:

10 miles per 1/4 hour

40 miles per hour

Step-by-step explanation:

Given that:

A car travels 20 miles in 1/2 hour

Miles traveled per hour :

(20 * 2) / 1 = 40 miles per hour

Mile traveled in 1/4 hour :

Distance = speed * time

Distance = 40 mph * 1/4 = 10 miles per 1/4 hour

Car traveling 30 miles in 3/4 hours

(30 * 4) /3 = 120 / 3 = 40 miles per hour

Distance = 40 mph * 1/4 = 10 miles per 1/4 hour

Answer: y = 4

Step-by-step explanation:

The equation y = 3 represents a vertical line. Thus, any equation in which y = m = 0 would be parallel to this line. Pick a random b-value and plug it into the equation with a slope of 0 and you should have a parallel line equation.

Twelve 10 dollar bills

Step-by-step explanation:

10, the value of a 10$ bill, times twelve equals 120$

Looks like the inequality is

-3n < 7n - 20 < 3n

Add 3n to each side:

0 < 10n - 20 < 6n

Solve the right inequality.

10n - 20 < 6n

Add -10n to both sides:

-20 < -4n

Divides both sides by -4:

5 > n

Now solve the left inequality, and take the intersection of the two solution intervals.

0 < 10n - 20

Add 20 to both sides:

20 < 10n

Divide both sides by 10:

2 < n

So 2 < n < 5. There are only 2 integers in this range (3 and 4), whose sum is 7.

Answer:

7

Step-by-step explanation:

We solve each of the two inequalities separately. To solve the first inequality, -3n<7n-20, we add 3n to both sides:

0<10n-20, then we add 20 to both sides to get

20<10n. Finally, dividing both sides by 10 gives 2<n, so n must be greater than 2.

For the second inequality, 7n-20<3n, we subtract 3n from both sides:

4n-20<0, then add 20 to both sides to get

4n<20. Finally, dividing both sides by 4 gives n<5, so n must be less than 5.

The only integers that are greater than 2 and less than 5 are 3 and 4. So, the sum of all possible integer values of n is 3+4=7.

Answer:

Answer A is Linear.  You can see this because each term is equal to the previous term plus a fixed amount (3), making it an arithmetic sequence.

Answer B is not linear.  This is because each term is a multiple of the previous one, making it a geometric sequence.

Answer:

Function A

Step-by-step explanation:

Each time x increases by 1, y increases by 3. Function B is exponential instead of linear, because y increases by a larger number each time rather than increasing by the same amount.

Answer:

The two column proof can be presented as follows;

1. [tex]\overline{AB}[/tex] ≅ [tex]\overline{CD}[/tex]      [tex]{}[/tex]               Given

2. [tex]\overline{AD}[/tex] ≅ [tex]\overline{CB}[/tex]      [tex]{}[/tex]              Given

3. [tex]\overline{BD}[/tex] ≅

4. ΔABD ≅ ΔBCD      [tex]{}[/tex]     SSS

Step-by-step explanation:

Given that we have;

Segment [tex]\overline{AB}[/tex] of triangle ΔABD being congruent to the corresponding segment [tex]\overline{CD}[/tex] of triangle ΔBCD and segment [tex]\overline{AD}[/tex] of triangle ΔABD being congruent to the corresponding segment [tex]\overline{CB}[/tex] of triangle ΔBCD, and that the common segment [tex]\overline{BD}[/tex] of both triangles are congruent by reflexive property, we have that ΔABD is congruent to ΔBCD by the Side-Side-Side (SSS) rule of congruency.

Answer:

a is positive and b is negative

Step-by-step explanation:

a is the slope, which is positive

b is the y intercept, where x = 0 and that is negative.

Hence 120 loads of laundry is required with jumbo jug of laundry detergent.

A sort of detergent (cleaning agent) used to clean soiled laundry is laundry detergent (clothes). There are two types of laundry detergent produced: powder (washing powder) and liquid. Builders (about 50% by weight), surfactants (15%), bleach (7%), enzymes (2%), soil deposition inhibitors, foam regulators, corrosion inhibitors, optical brighteners, color transfer inhibitors, perfumes, dyes, fillers, and formulation aids may all be present in laundry detergents.

∵ Number of jumbo jug = 150 /50

                                     n = 3

∴ Laundry loads required of detergent:

 = 40 * n

= 40 * 3

= 120 loads

Given:

Consider the tank that is filled with water drains at a rate of [tex]\dfrac{d^2}{16}+4d-100[/tex] gallons per minute where d is the depth of the tank in feet.

Depth of tank = 120 feet.

To find:

The rate of water drain for that tank.

Solution:

We have, rate of water drain in gallons per minute.

[tex]r=\dfrac{d^2}{16}+4d-100[/tex]

where, d is the depth of the tank in feet.

Put d=120, to get the rate of water drain for the tank.

[tex]r=\dfrac{120^2}{16}+4(120)-100[/tex]

[tex]r=\dfrac{14400}{16}+480-100[/tex]

[tex]r=900+380[/tex]

[tex]r=1280[/tex]

Therefore, the rate of water drain is 1280 gal/min. Hence, the correct option is B.
