A) 33.6 pints
B) 67.2 pints
C) 134.4 pints
D) 268.8 pints
Answers
Answer:
Both are C.
Step-by-step explanation:
16.8 gallons of water is equal to 67.2 quarts and 134.4 pints.
Final answer:
To convert gallons to quarts, multiply the number of gallons by 4, which gives us 67.2 quarts (Option C). To convert gallons to pints, multiply the number of gallons by 8, resulting in 134.4 pints (Option C).
Explanation:
The question pertains to converting units of volume from gallons to quarts and pints. Given that the aquarium has a capacity of 16.8 gallons and knowing that there are 4 quarts in a gallon, we multiply 16.8 by 4 to find the capacity in quarts:
16.8 gallons × 4 quarts/gallon = 67.2 quarts
Next, to find the number of pints, we consider that there are 8 pints in a gallon (since each quart is equivalent to 2 pints, and there are 4 quarts in a gallon). Thus, we multiply:
16.8 gallons × 8 pints/gallon = 134.4 pints
Trevor took big steps to find the length of the shadow of the big pine tree infront of the school
Answers
The big pine tree is approximately 64 feet tall, based on Trevor's estimates of its shadow and the building's shadow.
To find the height of the big pine tree, we can use proportions based on the relationship between the lengths of the shadows and the heights of the objects.
Let's denote:
[tex]- \( S_t \)[/tex] as the length of the shadow of the tree,
[tex]- \( H_t \)[/tex] as the height of the tree,
[tex]- \( S_b \)[/tex] as the length of the shadow of the building, and
[tex]- \( H_b \)[/tex] as the height of the building.
From Trevor's estimates:
[tex]- \( S_t = 48 \)[/tex] feet,
[tex]- \( S_b = 18 \)[/tex] feet, and
[tex]- \( H_b = 24 \)[/tex] feet.
We can set up a proportion to solve for [tex]\( H_t \):[/tex]
[tex]\[ \frac{H_t}{S_t} = \frac{H_b}{S_b} \][/tex]
Substituting the given values:
[tex]\[ \frac{H_t}{48} = \frac{24}{18} \][/tex]
Cross-multiplying:
[tex]\[ 18 \times H_t = 24 \times 48 \][/tex]
[tex]\[ 18H_t = 1152 \][/tex]
[tex]\[ H_t = \frac{1152}{18} \][/tex]
[tex]\[ H_t = 64 \][/tex]
Therefore, the big pine tree is approximately 64 feet tall.

A rectangle has a height of 5 and a width of 4x2 – 2x – 6.
Express the area of the entire rectangle
Expression should be expanded.
Answers
Answer:
The area of the rectangle is given by the expression "20x² - 10x - 30".
Step-by-step explanation:
The area of a rectangle is given by the product of it's dimensions. This is shown in the formula bellow:
area = width*height
In this case the width is an expression, so we need to multiply the numeric part of each mnemonic
area = 5*(4x² - 2x - 6)
area = 20x² - 10x - 30
The area of the rectangle is given by the expression "20x² - 10x - 30".

To figure this out, you must use the triangle inequality theorem. It says that the sum of 2 sides of the triangle should be more than the third side. If you add 8 and 12, you get less than 24 but if you add 12 and 24 or 8 and 24, you will get more. So, there are only 2 triangles! I hope this helps!
What is the solution to the system of equations 2x + 3y = 40 and y = x + 10?
x = 2; y = 12
x = 4; y = 14
x = 12; y = 2
x = 14; y = 4
Answers
Answer:
x=2, y=12
STEP BY STEP-
Replace the Y in 2x+3y=40 for X+10, because y=x+10. You now have 2x+3(x+10)=40. Now multiply the X and the 10 by 3, so you have 2x+3x+30=40. Combine like terms to get 5x+30=40. Subtract the 30 on both sides so you get 5x=10. Divide by 5 and that gives you the solution for X (2). Then, plug 2 in for X in the equation y=x+10. You now have Y=2+10. Combine like terms and you get 12, so Y=12.
Sorry that I'm so bad at explaining things
Final answer:
Substitute y = x + 10 into 2x + 3y = 40, simplify to 5x = 10, solve for x, then substitute x into the second equation to find y. The solution is x = 2 and y = 12.
Explanation:
The solution to the system of equations 2x + 3y = 40 and y = x + 10 can be found by substituting the second equation into the first. This is a common method for solving systems of linear equations, which involves elimination and substitution. We substitute y from the second equation into the first to get 2x + 3(x + 10) = 40, which simplifies to 2x + 3x + 30 = 40. After combining like terms, we have 5x = 10, which gives us x = 2. We then substitute x back into the second equation to find y. If x = 2, then y = 2 + 10, which means y = 12.
If AB = 9, RS = 3, and SC = 5, find BC.
A) 5
B) 10
C) 13.5
D) 15
Answers
Answer:
D
Step-by-step explanation:
Δ ABC and Δ RSC are similar triangles, thus the ratio of corresponding sides are equal, that is
[tex]\frac{BC}{SC}[/tex] = [tex]\frac{AB}{RS}[/tex], substitute values
[tex]\frac{BC}{5}[/tex] = [tex]\frac{9}{3}[/tex] = 3 ( multiply both sides by 5 )
BC = 5 × 3 = 15 → D
Answer:
BC=15, so D
Step-by-step explanation:
First, let's annotate. on line AB, write 9. RS, 3. SC, 5. These are the measurements of lines, not angles. We're trying to find the length of BC, the whole bottom side. Also, all of the little squares represent 90° angles, which means the triangles are also rational.
Lengths 3 and 9 are rational. 1:3. Since they're rational, the triangles are a set of dilations. Because of this, ALL the sides of the triangles are rational. If all the sides are rational by 1:3, which they are, then we can just multiply SC by 3. By doing this, we get the length of BC. Thus, the length of BC is 15.I REALLY hope this helps. If not, I encourage you to watch videos on dilations/rational triangles.

The equation in slope-intercept from is y = [tex]\frac{9}{8}x - \frac{3}{8}[/tex].
Step-by-step explanation:
Given,
x = 8t+3
y= 9t+3
First, convert both the equations in terms of t for comparison.
x = 8t + 3
x - 3 = 8t
t = [tex]\frac{x-3}{8}[/tex]
Similarly,
y = 9t + 3

t = [tex]\frac{y-3}{9}[/tex]
Now, comparing both equations
[tex]\frac{x-3}{8}[/tex] = [tex]\frac{y-3}{9}[/tex]
9x -27 = 8y -24
9x - 3 = 8y
or
y = [tex]\frac{9}{8}x - \frac{3}{8}[/tex]
Hence, the equation in slope-intercept from is y = [tex]\frac{9}{8}x - \frac{3}{8}[/tex].

The circumference of the circle rounded to the nearest whole number is 20 cm.
If Pi is approximated to 3.14, the circumference of the circle is 25.12 cm.
Answers
Answer:
The circumference of the circle in terms of π is 8π.
If π is approximated to 22/7, the circumference of the circle is approximately 25.14 cm.
If π is approximated to 3.14, the circumference of the circle is 25.12 cm.
Step-by-step explanation:
The circumference of the circle = 2*π*r
r = radius
r = d/2
r= 8cm/2 = 4cm
π = 3.14
The circumference of the circle = 2π(4)= 8π , so we have:
The circumference of the circle in terms of π is 8π.
Using pi = 22/7, we have:
The circumference of the circle = 2* 22/7 * 4 = 8* 22/7 = 25.14 cm, so we have:
If π is approximated to 22/7, the circumference of the circle is approximately 25.14 cm.
Using pi = 3.14, we have:
The circumference of the circle = 2* 3.14 * 4 = 8* 3.14 = 25.12 cm, so we have:
If π is approximated to 3.14, the circumference of the circle is 25.12 cm.
Here we want to see which statement is correct about a circle with a diameter of 8cm.
The correct options are
"The circumference of the circle in terms of Pi is 8 pi.""If Pi is approximated to StartFraction 22 over 7 EndFraction, the circumference of the circle is approximately 25.14 cm.""If Pi is approximated to 3.14, the circumference of the circle is 25.12 cm."Things that we must know about circles:
We know that for a circle of diameter D:
The radius is half the diameter, so R = D/2The circumference is pi times the diameter, so C = pi*DThe area is pi times the radius squared: A = pi*R^2So our circle of diameter of 8cm has:
Radius R = 8cm/2 = 4cmCircumference C = pi*8cm = 3.14*8cm = 25.12cmArea A = pi*(4cm)^2 = pi*16cm^2And if pi = 22/7, the circumference is:
C = (22/7)*8cm = 25.14cm
Then the correct statements are:
"The circumference of the circle in terms of Pi is 8 pi.""If Pi is approximated to StartFraction 22 over 7 EndFraction, the circumference of the circle is approximately 25.14 cm.""If Pi is approximated to 3.14, the circumference of the circle is 25.12 cm."If you want to learn more about circles, you can read:
