Answer:
The length of the ramp must be at least 14.71 feet
Step-by-step explanation:
Given
[tex]BC = 2.3ft[/tex]
[tex]\theta = 9^\circ[/tex]
See attachment for complete figure
Required
Length of the ramp (z)
To do this, we consider sin of angle A ([tex]\theta[/tex]).
So, we have:
[tex]sin\theta = \frac{Opposite}{Hypotenuse}[/tex]
This gives:
[tex]sin(9)= \frac{2.3}{z}[/tex]
Make z the subject
[tex]z= \frac{2.3}{sin(9)}[/tex]
[tex]z = \frac{2.3}{0.1564}[/tex]
[tex]z = 14.71 ft[/tex]
The length of the ramp must be at least 14.71 feet

7+12x=103 show how you checked it was right
Answer:
x=8. You plug 8 in for x.
7+12(8)=103
7+96=103
Step-by-step explanation:
7+12x=103
or 12x=103-7
x=96/12=8
to check it 8 is needed.
7+12×8=103

10/2.5=4
so x=4
Meg pounded a stake into the ground. When she attached a leash to both the stake and her dog’s collar, the dog could reach 9 feet from the stake in any direction. Using 3.14 for pi, what is the approximate area of the lawn, in square feet, the dog could reach from the stake.
The dog is able to run around in a circle with a radius of9 ft.
The area of a circle is A = pi r^2
A = (3.14) (9)^2
A= (3.14)(81)
A= 254.34 sq ft

Vanessa tried to prove that triangle KLM is congruent to triangle MNK. What is the first error Vanessa made in her proof?
Answer:
B. Vanessa only established some of the necessary conditions for a congruence criterion.
Step-by-step explanation:
The diagram does support the claim that \overline{KL}\cong\overline{MN}
KL
≅
MN
start overline, K, L, end overline, \cong, start overline, M, N, end overline because they both have two tick marks.
Step 1 is correct.
Step 2
The diagram does support the claim that \overline{LM}\cong\overline{NK}
LM
≅
NK
start overline, L, M, end overline, \cong, start overline, N, K, end overline because they both have a single tick mark.
Step 2 is correct.
Step 3
In this step, Vanessa claims that \triangle KLM\cong \triangle MNK△KLM≅△MNKtriangle, K, L, M, \cong, triangle, M, N, K using the side-side-side criterion. But Vanessa only established two pairs of congruent corresponding sides. To use this criterion, we must establish three pairs of congruent sides.
Vanessa would be able to use this criterion if she first established that \overline{MK}\cong\overline{KM}
MK
≅
KM
start overline, M, K, end overline, \cong, start overline, K, M, end overline (this can be done with the reason that line segments are congruent to themselves).
The first error Vanessa made in her proof was option B.
Vanessa only established two pairs of congruent corresponding sides
What is congruency?polygons are congruent if they may be identical in size and shape - that is, if their corresponding angles and sides are the same.
Congruent shapes are shapes that can be exactly equal. The corresponding facets are identical and the corresponding angles are equal.
⇒KL≅ MN 9K, L, end overline)
⇒LM≅ NK
⇒MNK△KLM≅△MNK (triangle, K, L, M)
Vanessa would be able to use this criterion if she first established that
⇒MK≅ KM

geometry: find the value of x. Round to the nearest tenth. How do I do this? screenshot attached
Answer:
[tex]\boxed {\boxed {\sf x \approx 105.3}}[/tex]
Step-by-step explanation:
To solve for x, remember the right triangle trigonometry ratios (soh-cah-toa).
sinθ= opposite/hypotenuse cosθ= adjacent/hypotenuse tanθ= opposite/adjacentIf we look at the angle given (θ), then we see that 36 is adjacent or next to the 70° angle. x is the hypotenuse because it is opposite the right angle. So, we have to use cosine (adjacent and hypotenuse).
[tex]cos (\theta)=\frac {adjacent}{hypotenuse}[/tex]
[tex]cos(70)=\frac{36}{x}[/tex]
Cross multiply. (Multiply the first numerator by the second denominator. Then, multiply the first denominator by the second numerator).
[tex]\frac{cos(70)}{1}=\frac{36}{x}[/tex]
[tex]cos(70)*x= 36[/tex]
Since we want to solve for x, we must isolate the variable. Divide both sides by the cosine of 70.
[tex]\frac{cos(70)*x}{cos(70)}=\frac{ 36}{cos(70)}\\x= 105.2569584[/tex]
Round to the nearest tenth. The 5 in the hundredth place tells us to round the 2 to a 3.
[tex]x \approx 105.3[/tex]
x is about 105.3

Answer:
(-5 1 0 0) and (-3 0 1 0)
Step-by-step explanation:
Based on my memory, you can use the dot product to find orthogonality meaning
u1 . u2 = 0
In this case, we let u be the arbitrary vector represented by (x y z w)
u . (1 5 3 0) can be expressed as an equation given by:
{(x y z w) | x + 5y + 3z + 0w= 0}
We solve this equation letting y = s and z = t and x = -5s -3t
Reconstruct this according to their variable will give
(-5 1 0 0)s + (-3 0 1 0)t = 0
So the basis vectors are (-5 1 0 0) and (-3 0 1 0).
Let c1 and c2 be arbitrary constants:
if you solve for c1(-5 1 0 0) + c2(-3 0 1 0) = 0
c1 and c2 should have only trivial solution, which proves its
linear independence and so it forms a basis vector space.

pam ate 9 nuts in 6 minutes . if she continued eating at the same rate,how many would she eat in:
[tex]a)12min[/tex]
[tex]b)4min[/tex]
[tex]c)1 \: hour[/tex]
Answer:
18 nuts in 12 minutes, 13.5 nuts in 4 minutes and 90 nuts in one hour
Step-by-step explanation:
12 min :
12/6 = 2
2 x 9 = 18 nuts in 12 minuts
4 min:
6/4 = 1.5
1.5 x 9 = 13.5 nuts in 4 minutes
(round to 13 if whole nuts only)
1 hour:
1 hour = 60 mins
60/6 = 10
9 x 10 = 90 nuts in one hour
