37. Watering a lawn requires 623 gallons of water for
every 1000 sq. ft. What is the rate of gallons per square
foot?
The rate of gallons per square foot is 0.624 gallons per square foot.
What is a rate?A rate demonstrates how many times one number can fit into another number. Ratios contrast two numbers by ordinarily dividing them. A/B will be the formula if one is comparing one data point (A) to another data point (B). This indicates that you're dividing information A by B.
In this scenario, watering a lawn requires 623 gallons of water for every 1000 sq. ft.
The rate of gallons per square foot will be:
= Number of gallons / Square foot
= 623 / 1000
= 0.623

In a company, there are 28 total employees. All employees who have worked there for more
than five years receive a gift.
If eleven employees have received the gift, what is the probability that a randomly
selected employee has received the 5-year gift?
The probability that a randomly selected employee has received the 5-year gift is 39.29%
What is the probability?Probability determines the chances that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability that a randomly selected employee has received the 5-year gift = number of employees who have received the gift / total number of employees
11/28 x 100 = 39.29%

Expand the following expression: 4 (2k + j)
Answer:
4(2k + j) = 8k + 4j
Step-by-step explanation:
4(2k + j)
Distribute in the 4.
4 * 2k + 4 * j
Multiply 4 and 2k.
8k + 4 * j
Multiply 4 and j.
8k + 4j
Answer:
[tex]\boxed{\sf{8k+4j}}[/tex]Step-by-step explanation:
Use the distributive property.
Distributive property:
⇒ A(B+C)=AB+AC
4(2k+j)First, multiply by expand.
→ 4*2k=8k
→ 4*j=4j
Rewrite the problem down.
= 8k+4j
[tex]\Longrightarrow: \boxed{\sf{8k+4j}}[/tex]
Therefore, the correct answer is 8k+4j.I hope this helps! Let me know if you have any questions.
Sal the sloth takes one hour to travel 7 1/2 feet. If he continues to travel at the same rate, how long will it take him to travel 30 feet?
Answer:
4 hours
Step-by-step explanation:
Since we know he travels at a rate of 1:7.5 all we have to do is divide 7.5 by 30. Do you use proportions? You can set this up as a proportion and the find answer easily.
1[tex]\frac{1}{7.5} =\frac{x}{30}[/tex]
Now we cross product.
7.5 multipled by x =7.5x
1x30=30
so now we have
7.5x=30
Now we have to divide 7.5 on both sides which gives us
x=4
Find the perimeter of the rectangle
below in inches.
Answer:
Perimeter of the rectangle is 28 yardsStep-by-step explanation:
Given:
Length of rectangle = 8 yardsBreadth of Rectangle = 6 yardsTo Find:
Perimeter of the rectangleSolution:
We know that,
Perimeter of rectangle= 2(L + B)Substituting the required values,
⇢ Perimeter = 2(8 + 6)
⇢ Perimeter = 2(14)
⇢ Perimeter = 28 yards
Hence,
Perimeter of the rectangle is 28 yardsJack and Diane want to meet for breakfast. Jack walks 1.5 mph and Diane walks 1 mph. They started 5 miles apart from each other. How long does it take them to meet up?

Does the equation below represent a lunar relationship? Justify your response. 2x - 5y= -15
Answer:
Yes, the equation represents a linear relationship.
Step-by-step explanation:
If you graph it, it is a line.
Also, the exponent on the x and the y is exactly 1. There are no variables in the denominator, nor inside a radical. There are no squared, cubes or higher exponents. All these things will make an equation NOT linear.

An irregular plane figure drawn on graph paper is framed 15 by 40 rectangle.To find its area,10,000 random points are generated,and 5,710 of them land inside the irregular region what is the area of the irregular region to the nearest integer
=========================================================
Explanation:
A = number of points that land inside the irregular figureB = number of randomly generated points totalIn this case,
A = 5,710B = 10,000Divide A/B to find the experimental probability of landing inside the figure
A/B = (5,710)/(10,000) = 0.571
There's about a 57.1% chance of landing inside the figure.
The entire region is 15 units by 40 units, giving an overall area of 15*40 = 600 square units.
Roughly 57.1% of this total area would be taken up by the irregular figure
57.1% of 600 = 0.571*600 = 342.6 which rounds to 343
The area of the irregular region is about 343 square units
In Exercise 3, one equation relating the times Eric spends running and walking to reach the goal of covering 1600 meters is 200x + 80y=1600. Suppose Eric runs and walks for a total of 12 minutes to reach his goal.
Answer + Step-by-step explanation:
let x be the time that Eric spends running
y be the time that Eric spends walking
a) the statement “Eric runs and walks for a total of 12 minutes to reach his goal” is equivalent to the equation: x + y = 12
b) the coordinates of the intersection point are (5.333... , 6.666...)
Interpretation:
the time that Eric spends running is 5.333... minutes
the time that Eric spends walking is 6.666... minutes
Answer:
Given equation:
[tex]200x+80y=1600[/tex]
where:
x = time Eric runs (in mins)y = time Eric walks (in mins)Part (a)If Eric runs and walks for a total of 12 minutes, then:
[tex]x+y=12[/tex]
Part (b)To graph:
Rewrite both equations to make y the subjectFind the x-interceptFind the y-interceptConnect the two points with a straight line[tex]200x+80y=1600 \implies y=20-\dfrac{5}{2}x[/tex]
[tex]\textsf{x-intercept}: \quad 20-\dfrac{5}{2}x=0 \implies x=8 \implies (8,0)[/tex]
[tex]\textsf{y-intercept}: \quad 20-\dfrac{5}{2}(0)=20 \implies (0,20)[/tex]
[tex]x+y=12 \implies y=12-x[/tex]
[tex]\textsf{x-intercept}: \quad 12-x=0 \implies x=12 \implies (12,0)[/tex]
[tex]\textsf{y-intercept}: \quad 12-0=12 \implies (0,12)[/tex]
Point of intersection (equate equations):
[tex]\begin{aligned}20-\dfrac{5}{2}x &=12-x\\20-12 &=\dfrac{5}{2}x-x\\8&=\dfrac{3}{2}x\\16 &=3x\\x &=\dfrac{16}{3}\end{aligned}[/tex]
[tex]y=12-\dfrac{16}{3}=\dfrac{20}{3}[/tex]
[tex]\implies \left(\dfrac{16}{3},\dfrac{20}{3}\right)[/tex]
The point of intersection tells us that Eric runs for 16/3 mins and walks for 20/3 minutes.

If you roll a fair 6-sided die and then flip a fair coin, what is the probability that you roll greater than 1 and get heads with the coin?
Answer:
5/12
Step-by-step explanation:
The odds for the die are 5 positive out of 6 possible outcomes
-- 2,3,4,5,6 are the positive outcomes - the ones you want - but there are a total of 6 outcomes or ways the die could land
The odds for the coin are 1 positive outcome out of 2 possible outcomes (heads or tails)
Once you have 5/6 for the die and 1/2 for the coin, you multiply them together.
choose all numbers that could be common denominators for 2/3 and 5/6
