Three side lengths of 5.2 cm, 6.3 cm and 10.5 cm will form exactly one unique triangle.
O True
O False
True, the three sides will form exactly one unique triangle.
What is a triangle?A triangle is three dimensional shape, whose third length is less than the sum of the first and second length.
let the first length = alet the second length = blet the third length = k(b - a) < k < (b + a)
(6.3 cm - 5.2 cm) < k (6.3 cm + 5.2 cm)
1.1 cm < k < 11.5 cm
The third length = 10.5 cm which is greater than 1.1 cm and less than 11.5 cm.
Thus, the three sides will form exactly one unique triangle.

Answer:
1. 3
2. -2
3. (1, 2)
Step-by-step explanation:
y axis is the numbered line that looks like the |
x axis is _
so the y int is 3 because A intercepts the y axis at 3
the y int for B is -2 because it intercepts the y axis at -2
the intersection of both lines is (1, 2) because you look and the point is at 1 for x and 2 for y
Answer:
y-intercept of line a: y=3
y-intercept of line b: y=-2
intersection: (1, 2)
Step-by-step explanation:
So the y-intercept of each line is where each line touches the y-axis.
The y-axis is the vertical line down the middle of the graph.
For line a, it touches the y-axis at 3, so we say the y-intercept is y=3.
For line b, it is the same thing, except it touched the y-axis at -2, so we say y=-2.
The intersection is the point at which both lines cross. In this graph, they cross the point (1, 2). Let me know if you need help figuring out how to do that.
Hope this helps!

A movie which ended at 8:15 p. M. Lasted for 3 hours and 40 minutes. At what time did the movie begin
Answer:4:35pm!
Step-by-step explanation:
Answer:
4:35 pm
Step-by-step explanation:
We are given the time that a movie ends, the duration of the movie, and we are asked to find the start time. Therefore, we just need to subtract the duration from the end time, and we'll have the start time.
First, we subtract the 3 hours from 8:15 pm, and that is 5:15.
*Remember that the minutes counter resets at 60*
Then we just subtract the 40 minutes, which means we end at 4:35.
find the coordinate of the point where y-4x=1
Answer:
(0, 1 )
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given
y - 4x = 1 ( add 4x to both sides )
y = 4x + 1 ← in slope- intercept form
with c = 1
the coordinates of the y- intercept are (0, 1 )
Jack is on one side of a 200 foot-wide canyon and Jill is on the other side. Jack and Jill can both see the trail guide at an angle of depression of 60 degrees. How far are they from the trail guide?
Answer:
Jack and Jill would each be [tex]200\; {\rm ft}[/tex] away from the trail guide.
Step-by-step explanation:
Refer to the diagram attached. Let [tex]\sf A[/tex] denote Jack, [tex]\sf I[/tex] denote Jill, and [tex]\sf G[/tex] denote the trail guide.
The angle [tex]\angle {\sf GAI} = 60^{\circ}[/tex] as it represents the depression angle of the trail guide from the perspective Jack. Likewise, [tex]\angle {\sf GIA} = 60^{\circ}[/tex] for the angle from the perspective of Jill.
Note that in triangle [tex]\triangle {\sf AGI}[/tex]:
[tex]\begin{aligned}\angle {\sf AGI} &= 180^{\circ} - \angle {\sf GAI} - \angle {\sf GIA}\\ &= 180^{\circ} - 60^{\circ} - 60^{\circ} \\ &= 60^{\circ} \end{aligned}[/tex].
Thus, triangle [tex]\triangle {\sf AGI}[/tex] would be an equilateral triangle as all its interior angles are [tex]60^{\circ}[/tex]. Therefore, the length of all three sides would be equal:
[tex]\overline {\sf AG} = \overline{\sf GI} = \overline{\sf AI}[/tex].
The length of segment [tex]\sf{AI}[/tex] represents the distance between Jack and Jill. This distance is supposed to be the same as the width of the canyon, [tex]200\; {\rm ft}[/tex]. Thus, [tex]\overline{\sf AI} = 200\; {\rm ft}[/tex].
The distance between Jack and the trail guide would be the same as the length of segment [tex]{\sf AG}[/tex], which is [tex]\overline{\sf{AG}} = \overline{\sf AI} = 200\; {\rm ft}[/tex].
Similarly, the distance between Jill and the trail guide would be the same as the length of segment [tex]{\sf GI}[/tex], which is [tex]\overline{\sf{GI}} = \overline{\sf AI} = 200\; {\rm ft}[/tex].
Ayshab walked x miles at 4 mph. She then walked 2x miles at 3 mph. The second part of the journey took 25 minutes longer than the first part of the journey. Find the value of x
The value of x will be equal to 5 / 12 for the given equation.
What is speed?Speed is defined as the ratio of the time distance travelled by the body to the time taken by the body to cover the distance.
From the given data we will form an equation
Ayshab walked x miles at 4 mph. She then walked 2x miles at 3 mph. The second part of the journey took 25 minutes longer than the first part of the journey
2x/3 = x/4 + 5/12
2x/ 3 = 3x/12 + 5/12
2x/3 = 3x + 5/2
24x = 9x + 5
15x = 15
X = 1
25 minutes/60 = 5/12
Therefore the value of x will be equal to 5 / 12 for the given equation.

which pair of ratios will make a proportion ?
Answer:
B. 3/5 and 9/15
Step-by-step explanation:
When looking for a proportion, you must look at a ratio that equals the same like:
1/2 = 2/4
You could see that I would just have to multiply or divide the numbers by 2.
So, that means they doubled.
3/5 = 9/15
How would you get 9 from 3? You would multiply by 3 to get 9.
Therefore, to check if it is a proportion, multiply with the same number you used to multiply the first number, which would be 3.
5 × 3 = 15.
Since 15 is written in the ratio, B would be the correct answer.
Therefore, B is the Correct Answer.

Melanie is looking for a loan. She is willing to pay no more than an effective rate of 9. 955% annually. Which, if any, of the following loans meet Melanie’s criteria? Loan A: 9. 265% nominal rate, compounded weekly Loan B: 9. 442% nominal rate, compounded monthly Loan C: 9. 719% nominal rate, compounded quarterly a. B only b. A and C c. A and B d. None of these fit Melanie’s criteria. Please select the best answer from the choices provided A B C D.
Melanie should take A and B, being r(loan a)= 9.699% annually, r(loan b)=9.862% annual
What options Melanie should choose for the best deal?It is given that
Loan A: 9.265% nominal rate, compounded weekly
In order to find the easiest effective rate, we need to divide this rate by 52 (which are the weeks in a year). Once we do that, we convert this effective weekly rate into an effective annual rate. Let´s walk you through all this.
[tex]r(Eweek)=\dfrac{0.09265}{52} =0.00178173[/tex]
Or 0.178173% effective weekly. Now we can transform it into an effective annual rate.
[tex]r(e,a)=1+(r(e.week))^{52} -1[/tex]
[tex]r(e,a)=1+(0.00178173)^{52} -1=0.09699[/tex]
Or 9.669% annual, which is less than 9.955%, so this one is selected, let´s check the next.
Loan B: 9.442% nominal rate, compounded monthly
Just like we did with Loan A, we need to divide this rate too, only this time, we will divide by 12, therefore obtaining an effective monthly rate.
[tex]r(Emonth)=\dfrac{0.09442}{12} =0.00786833[/tex]
Or 0.786833% effective monthly, let´s turn it into an effective annual rate.
[tex]r(e,a)=1+(r(e.month))^{12} -1[/tex]
[tex]r(e,a)=1+(0.00786833))^{12} -1=0.09862[/tex]
Or 9.862% annual, so this rate would work for Melanie too. This means that option C) is the answer we are looking for but, let´s walk that extra mile and turn that Loan C rate into an annual rate.
[tex]r(Eweek)=\dfrac{0.09719}{4} =0.0242975[/tex]
or 2.42975% effective quarterly, now, let´s convert it into an effective annual rate.
[tex]r(e,a)=1+(0.0 242975))^{12} -1=0.010079[/tex]
That is 10.079% effective annual, therefore, Loan C is not an option for Melanie.
Thus Melanie should take A and B, being r(loan a)= 9.699% annually, r(loan b)=9.862% annual
