Answer:
x=7.48
Step-by-step explanation:
13^2+x^2=15^2
169+x^2=225
x^2=56
x=7.48
Answer:
x = 7.48 (2d.p.) or 7.5 (1 d.p.)
Step-by-step explanation:
Use Pythagoras' Theorem.
15 x 15 (or 15²) = 225
13 x 13 = 169
√H - A = O
225 - 169 = 56
√56 = 7.48 (2d.p.) or 7.5 (1 d.p.)
re-write the equation in Ax+By=C form. use integers for A,B, and C.
y+2=-5(x-5)
Answer:
5x+y=23
Step-by-step explanation:
y+2=-5(x-5)
y+2=-5x+25
y=-5x+25-2
y=-5x+23
23=y-(-5x)
23=y+5x
5x+y=23

Step-by-step explanation:
After 5 hours, how far apart are the boats? Label the distance(s) on your drawing from the first problem.
Answer:
The distance between them is 277.84 m
Step-by-step explanation:
See comment for complete question.
Given
Boat A:
[tex]Speed = 24mph[/tex]
[tex]\angle A = 340^{\circ}[/tex]
Boat B:
[tex]Speed = 35mph[/tex]
[tex]\angle B = 200^{\circ}[/tex]
[tex]Time = 5hr[/tex]
First, we calculate the distance traveled by both boats in 5 hours
[tex]Distance= Speed * Time[/tex]
[tex]Boat\ A = 24mph * 5hr = 120m[/tex]
[tex]Boat\ B = 35mph * 5hr = 175m[/tex]
For more clarity, I'll make use of the attached image to represent the system.
From the attachment, we are to calculate distance C, but first we calculate the angle between them.
[tex]\theta = 340^{\circ} - 200^{\circ}[/tex]
[tex]\theta = 140^{\circ}[/tex]
C is then calculated using cosine law:
[tex]C^2 = A^2 + B^2 - 2BC\ Cos\theta[/tex]
This gives:
[tex]C^2 = 120^2 + 175^2 - 2*120*175\ Cos(140^{\circ})[/tex]
[tex]C^2 = 120^2 + 175^2 - 2*120*175*-0.7660[/tex]
[tex]C^2 = 14400 + 30625 + 32172[/tex]
[tex]C^2 = 77197[/tex]
Take square root of both sides:
[tex]C = \sqrt{77197[/tex]
[tex]C = 277.84[/tex]
The distance between them is 277.84 m

hi! im chimken and i have your answers!!!
1. polygon: is a closed figure where the sides are all line segments.
2. lateral face: a side of three-dimensional figure that is not a base.
3. pyramid: a solid figure that has a polygon for a base and triangles for sides. it is named for the shape of its base.
4. polyhedron: formed by two parallel, congruent, polygonal bases connected by lateral faces that are parallelograms.
5. i don't know this one :(
6. a net: a two dimensional representation of a three-dimensional figure that is unfolded along it's edges so that each face of the figure is shown in two dimensions.
7. face: is a plane figure that serves as one side of a solid figure.
8. i don't know this one :(
9. there are 4 possible answers. rectangular prism, sphere, cone, cylinder: 3D geometric shapes with the basic three-dimensional shapes.
10. triangular prism: with a known base and height of its face.
i hope this helped!!!

Can you find the midpoint of the segment with the following endpoints.
(-7,-5) and (-4,2)
9514 1404 393
Answer:
(-5.5, -1.5)
Step-by-step explanation:
The midpoint is the average of the end points:
((-7, -5) +(-4, 2))/2 = (-7-4, -5+2)/2 = (-11, -3)/2 = (-5.5, -1.5)
The midpoint of the segment is (-5.5, -1.5).
Enrique has $50 in his lunch account and spends $5 per day from the account. Maya has $46 in her lunch account and spends $4 per day from the account. Which equations model the situation?
50 – 5x = y and 46 – 4x = y
5x + 50 = y and 4x + 46 = y
5x – 50 = y and 4x – 46 = y
5 – 50x = y and 4 – 46x = y
Answer:
50 – 5x = y and 46 – 4x = y, is your answer

ANSWER FOR BRAINIEST
Could someone please tell me what this means? Like is it a/6 - 1/6?
Answer:
Yes, this is similar to [tex]\frac{a}{6} - \frac{1}{6}[/tex]
Answer:
yes
Step-by-step explanation:
Given
[tex]\frac{a-1}{6}[/tex]
Then each term on the numerator is divided by 6, that is
= [tex]\frac{a}{6}[/tex] - [tex]\frac{1}{6}[/tex]
