Answer:
5.4 mStep-by-step explanation:
Given
The top of the tree, the point A and the base form a right triangleHorizontal leg = 8 mVertical leg = the height of the tree = xAngle A = 34° is opposite to the threeUse the ratio to find the value of x:
opposite / adjacent = tan Ax/8 = tan 34°x = 8 tan 34 degreex = 5.4 m (rounded)A rectangle is 8 inches in length and it is 1 and 1/2 foot wide. What is the area 2 possible answers btw lol pls help asap!!
Answer:
Area = 144 inches2
or
Area = 1 feet2
Steps:
1.5 feet = 18 inches
Area = l × w
= 8 × 18
= 144 inches2
or
8 inches = 0.66666666666667 feet
Area = l × w
= 0.66666666666667 × 1.5
= 1 feet2

What is the missing side ?
Answer:
[tex]x=12[/tex]
Step-by-step explanation:
Method 1: Pythagorean Theorem
We can use the Pythagorean Theorem to solve for [tex]x[/tex]. The Pythagorean Theorem states that in a right triangle, the sum of the squares of the legs' side lengths is equal to the length of the hypotenuse squared. Simply put, [tex]a^{2} +b^{2} =c^{2}[/tex], where [tex]a[/tex] and [tex]b[/tex] are the legs and [tex]c[/tex] is the hypotenuse. In this case, we know that [tex]a=x[/tex], [tex]b=9[/tex], and [tex]c=15[/tex], so we get:
[tex]a^{2} +b^{2} =c^{2}[/tex]
[tex]x^{2} +9^{2} =15^{2}[/tex] (Substitute [tex]a=x[/tex], [tex]b=9[/tex], and [tex]c=15[/tex] into [tex]a^{2} +b^{2} =c^{2}[/tex])
[tex]x^{2} +81 =225[/tex] (Simplify exponents)
[tex]x^{2} +81-81=225-81[/tex] (Subtract [tex]81[/tex] from both sides of the equation to isolate [tex]x[/tex])
[tex]x^{2} =144[/tex] (Simplify)
[tex]\sqrt{x^{2}} =\sqrt{144}[/tex] (Take the square root of both sides)
[tex]x=12,x=-12[/tex] (Simplify, remember that each positive number has two square roots: a positive one and a negative one)
In the context of the situation, we know that [tex]x=-12[/tex] is an extraneous solution because a polygon cannot have negative side lengths. Therefore, the final answer is [tex]x=12[/tex].
Method 2: Pythagorean Triples
Method 1 works, but there's an easier way to find the value of [tex]x[/tex]. If we look at the given lengths of [tex]9[/tex] and [tex]15[/tex], we can observe that this triangle is a [tex]3-4-5[/tex] right triangle enlarged by a scale factor of [tex]3[/tex], because [tex]3*3=9[/tex] and [tex]5*3=15[/tex]. The only side length that's missing is the [tex]4[/tex]. Therefore, [tex]x=4*3=12[/tex]. Hope this helps!

which equation is the point-slope equation of the line that passes through the points (-2,-1) and (7,-4)?
Answer:
B (for question 7)
Step-by-step explanation:
To find the slope, we use the equation [tex]m=\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex].
m = (-4+1)/(7+2) = -3/9 = -1/3
Since B is the only option that would give a slope of -1/3, B must be the answer.
(you can use this same method for question 8)

Answer:
(2,10)
Step-by-step explanation:
so we can substitute the y = 5x into y = 6x - 2
so we would have
5x = 6x - 2
subtract 6x from both sides
-x = -2
remove the negative signs since they're on both sides
x = 2
so now we can substitute x = 2 into y = 5x
so we would get
y = 5(2)
y = 10
So the point will be (2,10)
Check:
y = 6x - 2
10 = 6(2) - 2
10 = 12 - 12
10 = 10
y = 5x
10 = 5(2)
10 = 10
Answer:
(2, 10)
Step-by-step explanation:
substitute the given value of y into the equation (y=5x)
6x-2 =5x
solve for x
"add" the -2 to the other side to leave the x by itself on one side
6x=5x+2
"subtract" the 5x to the other side to combine the x's
6x-5x=2
collect like terms
x=2
so you now have your x to solve for y
substitute the x into the equation (y=5x)
y=5(2)
simple
y=10
and there you have it!!
hope this helps!!!

Answer:
D. x = 18 cm , y = 9
Step-by-step explanation:
With reference angle 60
perpendicular (p) = 9[tex]\sqrt{3}[/tex]
base(b)= y
hypotenuse (h) = x
Then
sin 60 = p/h
[tex]\frac{\sqrt{3} }{2} = \frac{9\sqrt{3} }{x}[/tex]
x = 18
Now
cos 60 = b/h
1/2 = y/18
y = 9
Hope it will help :)
Answer:
it's answer is
D. = 18 and y = 9
The diagram shows a cuboid.
8 cm
15 cm
20 cm
What is the surface area of the cuboid?
Answer:
1160 cm^2
Step-by-step explanation:
Surface area=2(lw)+2(hl)+2(hw)
So, surface area=2(15x20)+2(8x15)+2(8x20)
=2(300)+2(120)+2(160)
=600+240+320
surface area=1160 cm^2.
The surface area of the cuboid is 1160 cm²
What is the surface area of cuboid?
The total surface area of the cuboid is given by the formula
Surface Area = 2 ( LH + LW + HW )
where ,
Length of the cuboid = L
Width of the cuboid = W
Height of the cuboid = H
Given data ,
Length of the cuboid L = 15 cm
Width of the cuboid W = 20 cm
Height of the cuboid H = 8 cm
Surface Area of the cuboid = 2 ( LH + LW + HW )
Substituting the values of L , H and W in the equation , we get
Surface Area of the cuboid = 2 ( ( 15 x 8 ) + ( 15 x 20 ) + ( 20 x 8 ) )
So ,
Total surface area of the cuboid = 2 ( 120 + 300 + 160 ) cm²
= 2 ( 580 ) cm²
= 1160 cm²
Hence , the Total surface area of the cuboid is 1160 cm²

I'm doing a math test, and I don't understand this question. How many 1/3 inch cubes does it take to fill a box with width 2 2/3 inches, length 3 1/3 inches, and height of 2 1/3 inches?
Answer: 62
Step-by-step explanation:
First and foremost, we have to calculate the volume of the box which will be:
= 2 2/3 × 3 1/3 × 2 1/3
= 8/3 × 10/3 × 7/3
= 560/27
= 20 20/27
The number of 1/3 inch cubes needed to fill the box will then be:
= 20 20/27 ÷ 1/3
= 560/27 ÷ 1/3
= 560/27 × 3
= 560/9
= 62 2/9
Therefore, 62 boxes can be filled

Dustin wants a new pair of shoes that cost $40. His mom pays 75% of the cost and dustin pays 25%. How much do they each pay?
Given:
Dustin wants a new pair of shoes that cost $40.
His mom pays 75% of the cost and dustin pays 25%.
To find:
How much do they each pay?
Solution:
We have,
Total cost of shoes = $40
His mom pays 75% of the cost.
[tex]\text{Mom pays}=\dfrac{75}{100}\times 40[/tex]
[tex]\text{Mom pays}=\dfrac{3}{4}\times 40[/tex]
[tex]\text{Mom pays}=30[/tex]
Dustin pays 25% of the cost.
[tex]\text{Dustin pays}=\dfrac{25}{100}\times 40[/tex]
[tex]\text{Dustin pays}=\dfrac{1}{4}\times 40[/tex]
[tex]\text{Mom pays}=10[/tex]
Therefore, Dustin pays $10 and his mom pays $30.

Step-by-step explanation:
The triangle is right angled meaning that one of the angles is 90⁰.
90+30+(9x-3)=180 (Angle sum property of a triangle)
