Find the volume of a pyramid with a square base, where the perimeter of the base is
16.9 cm and the height of the pyramid is 19.6. Round Your answer to the nearest tenth of the cubic centimeter.
Answers
Answer:
116.6
Step-by-step explanation:
Volume = ⅓ × area of base ×height. We don't have the area of base, we need to find it.
Perimeter (4×Length) = 16.9 cm
Length = 16.9÷4 = 4.225 cm
Area = L² = 4.225² =
Volume of pyramid = 1/3 × 4.225² × 19.6 = 116.624 = 116.6 cm³

Based on the information, it can be inferred that the difference in the circumference of the two circles is 6.31 cm.
How to calculate the circumference of a circle?To calculate the circumference of a circle we must apply the following formula:
2\(\pi\)RR = Radius of the circle.According to the previous formula, we must replace R with the radius of each of the radii of both circles as shown below:
2\(\pi\)1 = 6.282\(\pi\)2 = 12.59So, to find the difference of the circumferences of both circles we must subtract the smaller number (circumference of the small circle) from the larger number (circumference of the large circle).
12.59 - 6.28 = 6.31According to the above, the difference of the circumferences would be 6.31 cm.
How to calculate the area of the circle?To calculate the area of the circle we must apply the following formula.
A =\(\pi r^{2}\)
r = radio del círculo.
According to the above, the radiO of both circles would be:
\(\pi 1^{2}\) = 3.14\(\pi 2^{2}\) = 25.13Additionally, to find the difference we must subtract these values:

Answers
Answer:
A
Step-by-step explanation:
We can solve for H by isolating it on one side of the equation, as follows:
J/H - I/H = G
Taking H as the common denominator:
(J - I)/H = G
Multiplying both sides by H:
J - I = GH
Adding I to both sides:
J = GH + I
Dividing both sides by G:
H = (J - I)/G
So the answer is
(A)
H = (J - I)/G.
Answer: A
Step-by-step explanation:
\(\frac{J}{H} = G + \frac{I}{H}\) >Since you are solving for H bring I/H to the other side
by subtracting I/H from both sides
\(\frac{J}{H}- \frac{I}{H} = G\) >There is a common denominator so you can
combine the fractions
\(\frac{J-I}{H} = G\) >Multiply both sides by H or cross multiply whichever
way your mind things about how to get H on top
\(J-I = G(H)\) >Divide both sides by G
\(\frac{J-I}{G} = H\) >Answer is A
Mrs maggio needs 48 hot dogs harris teeter sells a 6 pack of hot dogs for 5.10$ and 8 pack for 6.88$ sould mrs maggio buy 8 six packs or 6,8 packs
Answers
Answer:
Eight 6-packs
Step-by-step explanation:
6-pack of hot dogs for 5.10$
8-pack of hot dogs for 6.88$
To figure out the answer, we compare the prices:
The price of six 8-packs is $41.28 ($6.88 x 6)
The price of eight 6-packs is $40.80 ($5.10 x 8)
As we can see, the cheaper option would be to buy eight 6-packs, which is our answer.

Keira said that if 6 tickets are sold, there should be 2 tickets left. Is Keira correct?
Answers
According to Keira, if 6 tickets are sold, there should be 2 tickets left. However, we don't have any information about the initial number of tickets available.
If the total number of tickets initially was 8, and 6 tickets were sold, then there would indeed be 2 tickets left, supporting Keira's statement.
However, if the total number of tickets initially was less than 8, or if the statement doesn't specify the initial number of tickets, we cannot determine if Keira's statement is correct.
Therefore, without additional information, we cannot determine the accuracy of Keira's statement.

Answer:

Step-by-step explanation:
Simplifying 5x + -9 = 3x + 15 Reorder the terms: -9 + 5x = 3x + 15 Reorder the terms: -9 + 5x = 15 + 3x Solving -9 + 5x = 15 + 3x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3x' to each side of the equation. -9 + 5x + -3x = 15 + 3x + -3x Combine like terms: 5x + -3x = 2x -9 + 2x = 15 + 3x + -3x Combine like terms: 3x + -3x = 0 -9 + 2x = 15 + 0 -9 + 2x = 15 Add '9' to each side of the equation. -9 + 9 + 2x = 15 + 9 Combine like terms: -9 + 9 = 0 0 + 2x = 15 + 9 2x = 15 + 9 Combine like terms: 15 + 9 = 24 2x = 24 Divide each side by '2'. x = 12 Simplifying x = 12

The following shows the process a student used to determine the number of yards in 3,218 meters. (1 mile = 1,609 meters) (1 mile = 1,760 yards) Step 1: 1,609 meters is being multiplied by conversion factor 1 mile over 3,218 meters equals 0.5 mile Step 2: 0.5 mile is being multiplied by conversion factor 1760 yards over 1 mile equals 880 yards Step 3: 880 yards What was the error made in this conversion? The 1 mile and 3,218 meters in Step 1 should be switched. The 1,609 meters and the 3,218 meters in Step 1 should be switched. The conversion factor should be added in Step 2 instead of being multiplied. The conversion factor should be divided in Step 2 instead of being multiplied.

A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answers
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day
Write an equation of the line that passes through each pair of points.

please provide explanations because i’m studying and point grinding WILL BE REPORTED
Answers
Answer:
\(y = \frac{1}{7} x - 1 \frac{6}{7} \)
Step-by-step explanation:
In y= mx +b, m is the slope and b is the y-intercept.
\(\boxed{slope = \frac{y1 - y2}{x1 - x2} }\)
where (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate
Slope
\( = \frac{ - 3 - ( - 2)}{ - 8 - ( - 1)} \)
\( = \frac{ - 3 + 2}{ - 8 + 1} \)
\( = \frac{ - 1 }{ - 7} \)
\( = \frac{1}{7} \)
Substitute m= ⅐ into the equation:
y= ⅐x +b
To find the value of b, substitute a pair of coordinates into the equation.
When x= -1, y= -2,
-2= ⅐(-1) +b
-2= -⅐ +b
b= ⅐ -2
\(b = - 1 \frac{6}{7} \)
Thus the equation of the line is \(y = \frac{1}{7} x - 1 \frac{6}{7} \).

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.
b) The correct expression is given as follows: -8.6b + 28.
How to simplify the expression?The expression in the context of this problem is defined as follows:
(-3.78b + 12) - (4.82b - 16).
The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:
-3.78b + 12 - 4.82b + 16.
This is the step where Maddie made the first error.
Then, to simplify the expression, we combine the like terms, as follows:
b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.
