Triangle JKL is equilateral. All three interior angles have equal measures.
What is the measure of exterior angle 1?
30 degrees
60 degrees
120 degrees
130 degrees
\( {\underline {\boxed {\Large {\bf \gray { {120}^{\circ} } }}}} \)
Given :
• In ∆ JKL , all the three interior angles have equal measures.
To calculate:• Measure of \( \angle \) 1 ( Exterior angle )
Calculation:Here, we can solve this question in two ways.
By exterior angle property of ∆.By linear pair.______________________________
Let us calculate the measure of interior angles first.
→ Let the measure of each interior angle be x.
As all the interior angles of the triangle are equal,
\( \sf { \dashrightarrow {180}^{\circ} = {x}^{\circ} +{x}^{\circ}+{x}^{\circ} } \)
[ By angle sum property of ∆ ]
\( \sf { \dashrightarrow {180}^{\circ} = {3x}^{\circ} } \)
\( \sf { \dashrightarrow \dfrac{{180}^{\circ}}{3} = {x}^{\circ} } \)
\( \sf\red { \dashrightarrow {60}^{\circ} = {x}^{\circ} } \)
Therefore, measure of each interior angle of the triangle is 60°.
By exterior angle property of ∆ :As we know that,
Sum of two opposite interior angles of ∆ = Exterior angle\( \sf { \dashrightarrow \angle 1 = \angle K + \angle L} \)
\( \sf { \dashrightarrow \angle 1 = {60}^{\circ} + {60}^{\circ} } \)
\( \sf \green { \dashrightarrow \angle 1 = {120}^{\circ} } \)
⇒ Hence, measure of angle 1 is 120°.
By linear pair:→ \(\angle \) 1 + \(\angle \) J = 180°
→ \(\angle \) 1 + 60° = 180°
→ \(\angle \) 1 = 180° - 60°
→\(\angle \) 1 = 120°
⇒ Hence, measure of angle 1 is 120°.

9. Expand using identites.
1) (3/2 m - 5n) (3/2 m + 5n)
Answer:
(3/2 m)^2 -(5n)^2^
Step-by-step explanation:
Answer: 9m^2 / 4 - 25n^2
Step-by-step explanation:
Use the identity: (a-b)(a+b)=a^2 - b^2
substitute values of a and b, where a=3/2m and b=5n.
The following simplifies to (3/2m)^2 - (5n)^2.
Basketball tickets were $5 for the floor seats and $2 for the grandstand seats
If 210 people attended and paid $660, how many people bought floor seats?
Answer:
Good seats sold=80
Poor seats sold=130
Step-by-step explanation:
g + p = 210 seats. Then p = 210 - g.
($5)g + ($2)p = $660. Substite 210 - g for p,
($5)g + ($2)(210 - g) = $660
Simplify, 5g + 420 - 2g = 660 => 3g = 240 => g = 80
80 and 130

what point below is the solution to the expression 2x+y=12
A) (4,2) C) (8,-1)
B) (3,6) D) (0,6)
Answer:
Step-by-step explanation:
It's B.
Let's rewrite the expression like this :
2x+y=12 ⇒ y=12-2x
and try given values for x :
if x=4 ⇒ y=12-(2×4)=12-8=4 ( so it is not 2 ) ⇒ wrong if x=3 ⇒ y=12-(2×3)=12-6=6 (it is 6) ⇒ right if x=8 ⇒ y=12-(2×8)=12-16=-4 (so it is not -1) ⇒ wrong if x=0 ⇒ y=12-(2×0)=12-0=12 (so it is not 6) ⇒ wrongThe snowfall data for Resort A are close to symmetric when they are shown in a box plot. The snowfall data for Resort B are not symmetric when they are shown in a box plot. Why is a box plot a good method to compare the data?
Answer:
Box and whisker plots are ideal for comparing distributions because the centre, spread and overall range are immediately apparent
Step-by-step explanation:
It is often used in explanatory data analysis
hope this helped
Answer:
When comparing two sets of data, a box plot can show whether either set of data is symmetric. If the data are symmetric, then the mean equals the median. If the data are not symmetric, then the median will be a better measure of center than the mean.

Compare the dimensions of the prisms. How many times greater is the surface area of the green prism than the surface area of the blue prism?
the green prism has a height of 25 cm, a depth of 5 cm, and a length of 10 cm
the blue prism has a height of 10 cm, a depth of 2 cm, and a length of 3 cm
PLEASE HELP!!
Comparing the dimensions of the prisms, the number of times in which the surface area of the green prism is greater than the surface area of the blue prism is 7.59
Surface area of a prismThe formula for the surface area of a prism is SA=2B+ph, where B, again, stands for the area of the base, p represents the perimeter of the base, and h stands for the height of the prism.
Area of the base of prism = lw
Perimeter of the base of a prism = 2(l+w)
Surface area of the green prism
height of 25 cm, a depth of 5 cm, and a length of 10 cm
Area of the base of prism = lw = 10cm × 5cm = 50cm²
Perimeter of the base of a prism = 2(l+w) = 2(10+5) = 30cm².
SA=2B+ph
= 2 ( 50) + 30 × 25 = 100+750= 850cm²
Surface area of the blue prism
height of 10 cm, a depth of 2cm, and a length of 3cm
Area of the base of prism = lw = 3cm × 2cm = 6cm²
Perimeter of the base of a prism = 2(l+w) = 2(3+2) = 10cm².
SA=2B+ph = 2(6) + 10 × 10 = 112cm²
The number of times green prism is greater than blue prism = 850cm²/112cm² = 7.59

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30

If we are given the equation of a line in this format:
y=mx+b
then it is quite simple to find the gradient and y-intercept.
In the format:
y=mx+b
the m represents the gradient (slope) and b represents the y-interpcept.
1) y=2x+3
gradient= 2
y-intercept= 3
2) y=x-5
gradient= 1
y-intercept= -5
3) y=-2x-4
gradient= -2
y-intercept= -4
4) y=5-x
gradient= -1
y-intercept= 5
5) y=3x+8
gradient= 3
y-intercept= 8
6) y= 1/4x+3
gradient= 1/4
y-intercept= 3

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Step-by-step explanation:
A rectangular prism is 2 inches by 4 inches by 6 inches.
Kimaya says, “It takes more 2/5-inch cubes to fill the prism than 1/5-inch cubes.”
Do you agree with Kimaya? Explain or show your reasoning.
No, I do not agree with Kimaya. The volume of the rectangular prism is 2 inches x 4 inches x 6 inches = 48 cubic inches. To fill the rectangular prism with 2/5-inch cubes, you would need 48 cubic inches / (2/5) cubic inches per cube = 120 cubes. To fill the rectangular prism with 1/5-inch cubes, you would need 48 cubic inches / (1/5) cubic inches per cube = 240 cubes.
So, it takes less 2/5-inch cubes to fill the prism than 1/5-inch cubes.
Another way to think of it is that the larger the cubes, the less number of cubes you need to fill the same volume, as the cubes are larger in size.
