Answer:

30 gallons

Step-by-step explanation:

if it fills up 1600 tubs an hour then the answer should be 30 gallons.

Answer:

220

Step-by-step explanation:

There are about 20 miles worth of gas per gallon so 20 x 11 = 220

Florence should buy 6 gallons of sealant for 1200 ft² of decking.

A ratio indicates the number of times one number contains another.

Given that, 400 ft² of decking requires 2 gallons of sealant.

400 ft² = 2 gallons

400 ×3 ft² = 2 × 3 gallons

1200 ft² = 6 gallons

Hence, Florence should buy 6 gallons of sealant for 1200 ft² of decking.

Answer:

y = -2x + 10

Step-by-step explanation:

The slope of a perpendicular line is the opposite reciprocal of the original line.

1/2 -> -2/1 -> -2

Solve for the new y-intercept using the point we are given.

y = 2x + b

4 = 2(-3) + b

4 = -6 + b

10 = b

Fill in everything we solve for in slope-intercept form [ y = mx + b ]

y = -2x + 10

Best of Luck!

Answer:

It has 8 significant figures

Step-by-step explanation:

Product of 11,435 meters and 19.35 meters

Product means multiplication(×)

= 11,435 × 19.35

= 221,267.25

Product of 11,435 meters and 19.35 meters = 221,267.25

It has 8 significant figures

Significant figures are non-zero digits or trapped zeros

Answer:

D. 1

Step-by-step explanation:

If you take any two points (x, y), the slope is found by taking the difference of the y-coordinates and dividing that by the difference of the x-coordinates.

Here, we actually are given 4 points of the form (x, y), so we can just arbitrarily choose any two. I'll just go with the first two: (-2, 0) and (1, 3).

The difference of the y-coordinates is:

3 - 0 = 3

The difference of the x-coordinates is:

1 - (-2) = 3

Dividing these gives:

3/3 = 1

The slope is thus 1, and the answer is D.

Answer:

in 4 hrs she earned $24. So each hour she is paid $6

Step-by-step explanation:

Answer:

64 DVDs

Step-by-step explanation:

25% = 16 DVDs

25%x 4 = 16x 4

100% = 64 DVDs

If action movies make up 25% of Sara’s DVD collection. If she has 16 action DVDs, how many DVDs does Sara have in her collection will be 64

First step is to convert the decimal to fraction

16÷24÷100

Second step is to reduce the fraction

16÷1÷4

Third step is to divide the fraction by multiplying its reciprocal in order to determine how many DVDs does Sara have in her collection

16×4

=64

Inconclusion if action movies make up 25% of Sara’s DVD collection. If she has 16 action DVDs, how many DVDs does Sara have in her collection will be 64

Answer: 53°

Step-by-step explanation: If two parallel lines are cut by

a transversal, then same-side interior angles are supplementary.

So if we know one of our angles measures 127,

our other angle will measure 180 - 127, which is 53.

So x is 53 degrees.

Remember, whenever you have two parallel lines cut by a transversal,

same-side interior <'s are supp. or the sum of their measures is 180 degrees.

Answer: $10.7

Step-by-step explanation:

The following can be deduced from the question:

Total cost of items = $130

Percentage of Sales tax = 8.25%

Sales tax = Sales tax percent × Cost

Sales tax = 8.25% × $130

Sales tax = 8.25/100 × $130

= 0.0825 × $130

= $10.725

= $10.7

Answer:

k = p(K+t)

Step-by-step explanation:

p = k/K+t // × (K+t)

p(K+t) = k

Answer:

k = K p - K t

Step-by-step explanation:

Solve for k:

p = k/K + t

p = k/K + t is equivalent to k/K + t = p:

k/K + t = p

Subtract t from both sides:

k/K = -t + p

Multiply both sides by K:

Answer: k = K p - K t

Answer:

(a) 0

(b) -3/26

Step-by-step explanation:

(a)

We essentially plug 1 in for x and 2 in for y.

Our expression is [tex]\frac{2x-y}{y^2+1}[/tex], so making the correct substitutions yields:

[tex]\frac{2x-y}{y^2+1}=\frac{2*1-2}{2^2+1}=\frac{2-2}{4+1} =\frac{0}{5} =0[/tex]

So, the answer for part (a) is 0.

(b)

Again, we're now plugging in 1 for x and 5 for y:

[tex]\frac{2x-y}{y^2+1}=\frac{2*1-5}{5^2+1}=\frac{2-5}{25+1} =\frac{-3}{26} =-\frac{3}{26}[/tex]

So, the answer for part (b) is -3/26.

Step-by-step explanation:

So we have the rational expression [tex]\frac{2x -y}{y^{2} +1}\\[/tex]. All we have to do is to just plug the given values for what x and y are.

[tex]\frac{2x -y}{y^{2} +1}\\ \frac{2(1) -(2)}{(2)^{2} +1} \\ \frac{2 -(2)}{4+1} \\ \frac{0}{5} \\ 0[/tex]

[tex]0[/tex]

[tex]\frac{2x -y}{y^{2} +1}\\ \frac{2(1) -(5)}{(5)^{2} +1} \\ \frac{2 -(5)}{25+1} \\ \frac{-3}{26} \\ -\frac{3}{26}[/tex]

[tex]-\frac{3}{26}\\[/tex]

Answer:

The coordinates of b are: B=(-7,-8)

Step-by-step explanation:

We are given the coordinates of the midpoint of [tex]\overline{\text{AB}}[/tex] as M=(-5,-2).

We are also given the coordinates of A=(-3,4). The question requires us to calculate the coordinates of the other endpoint B.

Let (xb,yb) the coordinates of B. The coordinates of the midpoint can be calculated as follows:

[tex]\displaystyle x_m=\frac{x_a+x_b}{2}[/tex]

[tex]\displaystyle y_m=\frac{y_a+y_b}{2}[/tex]

We know xa=-3 and xm=-5. Solve the first equation for xb:

[tex]2x_m=x_a+x_b\Rightarrow x_b=2x_m-x_a[/tex]

Substituting:

[tex]x_b=2\cdot (-5)-(-3)=-10+3[/tex]

[tex]x_b=-7[/tex]

We can solve the second equation for xb and get:

[tex]y_b=2y_m-y_a[/tex]

Since ya=4 and ym=-2, then:

[tex]y_b=2\cdot (-2)-(4)=-4-4[/tex]

[tex]y_b=-8[/tex]

Thus, the coordinates of b are: B=(-7,-8)

Answer:

The first bank with the four letter code has the grater probability of me guessing the code.

Step-by-step explanation:

To break the code for the first bank which uses four letters, since there are 26 letters in the alphabet, and require a four letter code, the first letter can be any of the 26 letters. Since one letter has been taken, we are left with 25 letters for the second position, 24 for the third position and 24 for the fourth position.

So, the total number of ways of selecting the 4 letter code without repetition is ²⁶P₄ = 26 × 25 × 24 × 23 = 358800

Since we have only 1 correct code, this is our required outcome. So,  the probability of breaking the code is P = required outcome/total outcome = 1/358800 = 2.787 × 10⁻⁶

To break the code for the second bank which uses 6 digits with repetition, since there are 10 digits, and we require a 6 digit code, each digit can be filled with 10 digits each. Since there is repetition, the total number of ways we can select the 6 digits is (¹⁰P₁)⁶ = 10 × 10 × 10 × 10 × 10 × 10 = 10⁶.

Since there is going to be only 1 correct code, the number of ways of selecting the correct code is 1.

The probability P' of cracking the second bank code is P' = required outcome/total outcome = 1/10⁶ = 1 × 10⁻⁶

Since P = 2.787 × 10⁻⁶ > P' =  1 × 10⁻⁶, the first bank with the four letter code has the grater probability of me guessing the code.
