Answer:
Transversals? Transversals are different from traversals.
Step-by-step explanation:
Transversals always go through parallel lines. Okay, here are the rules. All pairs of alternate interior angles, alternate exterior angles, and corresponding angles are congruent pairs if the lines the transversal intersects are parallel, in which case each pair of consecutive interior angles are supplementary. That’s four rules right there.
Here are four more. If any of those pairs is congruent or supplementary, the lines the transversal intersects are parallel.
Vertical angles are always congruent, and any two angles that form a linear pair are supplementary. When you know all these rules, you can take the measure of any angle in the diagram and determine the measures of all the other angles as long as the lines intersected by the transversal are parallel.
a child should no longer play in the kid zone area when they reach 4'4" tall joe is 54" tall is he allowed to play in the kid zone area
Answer: No.
Step-by-step explanation: Joe is 4'6" tall. Convert 54" to feet by dividing by 12. 54/12=4.5. Half of a foot is 6 inches.
Joe is 54 inches tall, which is taller than the kid zone's maximum allowed height of 52 inches (4 feet 4 inches). Therefore, he is not allowed to play in the kid zone area.
To determine if Joe is allowed to play in the kid zone area, we must compare his height to the maximum height allowed for the kid zone. The maximum height for the kid zone is 4 feet 4 inches, which needs to be converted to inches to compare easily with Joe's height.
First, we know that 1 foot equals 12 inches. So, 4 feet is equal to 4 x 12 inches, which is 48 inches. Adding the extra 4 inches from the height limit gives us 48 + 4 inches, which is 52 inches. This is the maximum height allowed for the kid zone.
Since Joe is 54 inches tall, which is greater than the maximum 52 inches, it means he is too tall to play in the kid zone. Therefore, he is not allowed to play there according to the height restriction.

Some of the students at Kahlo Middle School like to ride their bikes to and from school. They always ride unless it rains. Let d be the distance in miles from a student's home to the school. Write two different expressions that represent how far a student travels by bike in a four week period if there is one rainy day each week.
Answer:
32d
Step-by-step explanation:
-The students ride their bikes to and from school every day. The distance is thus;
[tex]d_t=2d[/tex]
-Taking that there are 5 school days per week and that it rains in one per week. the total number of days is:
[tex]Days=Days \ per \ week \times \ number \ of \ weeks\\\\=(5-1)\times 4\\\\=16\ days[/tex]
Now, we multiply the distance per day by the total number of days:
[tex]Distance, D=2d\times 16\\\\=32d[/tex]
Hence, the total distance in a 4-week period is expressed as 32d ( where d is the distance from home to school).

Both figures have 9 congruent small cubes with
side length of 1 unit. Please find attached file in
order to compare and contrast the two figures
in terms of surface area and volume.
Answer:
Fig. 1 has less surface area than Fig. 2, but both figures have the same volume.
Step-by-step explanation:
The formulas for the surface area and volume are equal to:
[tex]A_{s} = n_{s} \cdot l^{2}[/tex]
[tex]V = n_{v}\cdot l^{3}[/tex]
Where:
[tex]n_{s}[/tex] - Number of faces.
[tex]n_{v}[/tex] - Number of cubes.
[tex]l[/tex] - Length of a cube side.
Surface Area
Fig. 1 has 34 faces, whereas Fig. 2 has 36 faces. The surface area are, respectively:
Fig. 1
[tex]A_{s} = 34\cdot (1\,u)^{2}[/tex]
[tex]A_{s} = 34\,u^{2}[/tex]
Fig. 2
[tex]A_{s} = 36\cdot (1\,u)^{2}[/tex]
[tex]A_{s} = 36\cdot u^{2}[/tex]
Fig. 2 has more surface area than Fig. 1
Volume
Fig. 1 has 9 cubes, whereas Fig. 2 has 9 cubes.
Fig. 1
[tex]V = 9\cdot (1\,u^{3})[/tex]
[tex]V = 9\,u^{3}[/tex]
Fig. 2
[tex]V = 9\cdot (1\,u^{3})[/tex]
[tex]V = 9\,u^{3}[/tex]
Both have the same volume.
Answer:
The two figures have equal volume, but different surface areas.
Step-by-step explanation:
Since the small cubes are congruent with side length of 1 unit, the area of its surfaces is 1 squared unit.
For fig 1, the surface area = number of faces × 1 squared unit
= 34 ×1 squared unit
= 34 squared unit
For fig 2, the surface area = number of faces × 1 squared unit
= 38 × 1 squared unit
= 38 squared unit
The volume of a cube = 1 cube unit
For fig 1, volume = number of cubes ×1 cube unit
= 9 × 1 cube unit
= 9 cube unit
For fig 2, volume = number of cubes ×1 cube unit
= 9 × 1 cube unit
= 9 cube unit

Apply the distributive property to factor out the greatest common factor. 24+32p =
Answer: 8(4p + 3)
Step-by-step explanation: Let's first rewrite this as 32p + 24.
If you're asked to factor a polynomial, the first thing you want to look for is the greatest common factor between the terms that are involved.
So what is the greatest common factor between 32p and 24?
Well if you use a factor tree, you'll figure out that the greatest common factor between 32p and 24 is 8.
What that means is that 2 factors out of this polynomial and what you're left with is each of these terms divided by the number that factors out.
In other words 32p divided by 8 or 4p and 24 divided by 8 which is 3.
So your answer is 8(4p + 3) and that is a factored version of 24 + 32p.
Answer:
8(4p + 3)

y varies directly with x. If x=6 when y=30, determine y when x=8.
Answer:
Y=40
Explanation:
Due to the nature of both X and Y varying directly, you can view the problem as a proportion. If x=6 and y=30, that must mean that when x=8 y must equal 40.
6:30 = 8:40
or
30/6= 5
Y/8= 5
Because they vary directly they are equivalent, and so multiply 8 by 5 and get 40.
Answer:40
Step-by-step explanation:
6 times 5 is 30
so 8 times 5 = 40

Fran budgets $205 dollars for groceries each month.
Mr abbot mowed1/4 of his lawn .his son mowed 3/7 of it who mowed most of the lawn how much of the lawn still needs to be mowed
Mr Abbot's son mowed more of the lawn. In total, they mowed 19/28 or approximately 68% of the lawn. Hence, approximately 32% or 9/28 of the lawn still has to be mowed.
Explanation:To find out who mowed more lawn and how much of the lawn is still left to be mowed, we need to compare the fractions and then add them together.
Mr. Abbot mowed 1/4 of his lawn and his son mowed 3/7 of it. To compare these fractions, you can turn them into decimals or percent by dividing the numerator (the top number) by the denominator (the bottom number). Doing that, we find Mr. Abbot mowed 0.25 (or 25%) of the lawn and his son mowed approximately 0.43 (or 43%) of the lawn. Therefore, the son has mowed more lawn.
To figure out how much lawn is still left to be mowed, we add up the fractions of the lawn that Mr. Abbot and his son mowed: [tex]1/4 + 3/7 = 7/28 + 12/28 = 19/28[/tex]. Thus, 19/28 of the lawn have been mowed, and to figure out what fraction is left, we subtract this number from 1 since 1 represents the whole or 100% of the lawn: [tex]1 - 19/28 = 9/28[/tex]. So, 9/28 of the lawn still needs to be mowed.

Find the area of a regular hexagon with an apothem of 15cm
Final answer:
The area of a regular hexagon with an apothem of 15 cm is approximately 1166.55 cm².
Explanation:
The area of a regular hexagon can be found by using the formula:
Area = (3 x apothem x side length) / 2
In this case, the apothem is given as 15 cm. We need to find the side length to calculate the area. The side length can be found using the formula:
side length = 2 x apothem / tan(180° / 6)
Using a calculator, we can find that the side length is approximately 25.98 cm. Plugging in the values into the area formula, we get:
Area = (3 x 15 cm x 25.98 cm) / 2 = 1166.55 cm²

From the equation, find the axis of symmetry of the parabola.
y = 3x2 - 12x+11
a. x = -2
b. x = 2
c. x = 1
d. x = -1
Answer:
B. x=2
Step-by-step explanation:
The formula to find the axis of symmetry is -b/2a.
So, in this case, we find our b and a, which are 3 and -12.
Plug them into the formula.
-(-12)/2(3)
The negative sign times another negative makes it into a positive, now we have a positive 12 and then 2 multiplied by 3 equals 6.
Our new equation is 12/6.
Then, simply solve it, 12 divided by 6 equals 2.
Therefore, B would be your answer, x=2.
The axis of symmetry of the parabola defined by the equation y = 3x^2 - 12x + 11 is x = 2.
Explanation:To find the axis of symmetry of the parabola defined by the equation y = 3x2 - 12x + 11,
we can use the formula for the axis of symmetry for a parabola in standard form which is x = -b/2a.
In this equation, a is the coefficient of x2, which is 3, and b is the coefficient of x, which is -12.
Plugging the values into the formula, we get x = -(-12)/(2*3) = 12/6 = 2.
Therefore, the axis of symmetry of the given parabola is x = 2.

Find the absolute error and the percent error of the police officer's estimate. If necessary, round your answers to the nearest tenth
Answer:
The absolute error is 0.2
The percent error is 1.45
Step-by-step explanation:
Please kindly check the attached for explanation
The absolute error of the police officer's estimate is 0.2, and the percent error is approximately 1.5%
Explanation:In Mathematics, absolute error is determined by the absolute value of the difference between the estimated value and the actual value. Therefore, the absolute error in this case is |14 - 13.8| = 0.2.
Percent error, on the other hand, is calculated by first finding the absolute error, then dividing the absolute error by the actual measurement, and finally multiplying the result by 100% to turn it into a percentage. So in this case, the percent error is given by (0.2 / 13.8) * 100 = 1.45%. Since we should round it off to the nearest tenths, the percent error will be roughly 1.5%.
