Answer:
I think 157 pavers
Step-by-step explanation:
I may be able to help with number 10, if the trees are to be decorated with a ring of decorative pavers then we have to find the circumference, if the radius is 5 then using the circumference formula, 2×3.14(pi)×the radius, you'll get 31.4 and since there is 5 trees to be decorated then multiply 31.4 times 5 which will give you 157 feet of pavers to surround all five trees. I apologize if it is incorrect.
Please Help! The graph relates the height of the water in a tank y (in inches) to the volume of the water x (in gallons).
A. Is the relationship proportional?
B. Write an equation of the line and interpret the slope.
C. What is the height of the water in the tank when the volume is 250 gallons?
The graph is attached.
Answer:
I Believe it is B
Step-by-step explanation:
x=100 and y=6
A. The relationship is directly proportional.
B. The required equation is x = 20y
C. The height of the water is 12.5 inches.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
From the graph, we obtain two pair of points (1, 20) and (2, 40).
∴ Slope(m) = (2 - 1)/(40 - 20) = 1/20.
Now, 40 = 20(2) + b.
b = 0.
So, y = 20x is the required equation.
A. The relationship is directly proportional.
B. The required equation is x = 20y.
C. The height o the water when the volume is 250 gallons is 250 = 20y
y = 12.5 inches.

Name some questions that you would include in the survey. Explain why you think those questions would be important to ask. b. Read through the paragraph below that describes some of the survey results. Then, identify the population characteristics and the sample statistics. About 3 4of the students surveyed eat the school lunch regularly. The median number of days per month that students at Blake Middle School ate a school lunch was 18 days. 36% of students responded that their favorite fruit is bananas. The survey results for Tanya’s seventh-grade homeroom showed that the median number of days per month that her classmates ate lunch at school was 22, and only 20% liked bananas. The fiesta salad was approved by 78% of the group of students who tried it, but when it was put on the lunch menu, only 40% of the students liked it. Of the seventh graders as a whole, 73% liked spicy jicama strips, but only 2 out of 5 of all the middle school students liked them.

Two of the lowest temperatures ever recorded in the U.S. are -79.8 *F in Alaska and -69.7*F in Montana. Write an inequality that compares the temperatures.
Answer:
During cool or cold weather episodes, fuel must be consumed to make buildings comfortable living spaces. A useful indicator of fuel consumption for heating purposes is the determination of heating degree-days. They are calculated by accumulating one heating degree-day (HDD) unit for each Fahrenheit degree the daily mean (average) temperature is below the base value of 65°F (18°C). For example, a day with a maximum temperature of 60°F and a minimum of 40°F has a mean temperature of 50°F. Subtracting 50 from 65 yields 15 heating degree-day units for that day. Hence, a day with a high temperature of 45°F and a low of 25°F produces ______ HDDs.

1. −2x + 6 = -16
2. -10 + 5x = -45
Can you help me?
Answer:
for the first one, it's x=11. first, you have to subtract 6 from both sides (-2x+6-6=-16-6) then you simplify that so you get -2x=-22, and from there you divide both sides by -2
getting -2x/-2=-22/-2 then you simplify that and get x=11
and for the second one x=-7. first, you have to add 10 to both sides
(-10+5x+10=-45+10) then simplify that down to 5x=-35 then divide both sides by 5 (5x/5=-35/5) then simplify that down to x=-7

Answer:
1/4096
Step-by-step explanation:
A negative exponent becomes a fraction. 4*3=12. 2^12=4096, so since it's a negative exponent you put it as a fraction. So it's 1/4096.
The simple exponential notation is 4,096.
What is Multiplication?
To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.
Given that;
The exponential notation is;
⇒ [tex](2^{-4} )^-^3[/tex]
Now, Solve the exponential notation as;
⇒ [tex](2^{-4} )^-^3[/tex] = [tex]2^{-4*-3}[/tex]
= [tex]2^{12}[/tex]
= [tex]4096[/tex]
Hence, The simple exponential notation is 4,096.
