Jen and Holly are on the Athletic council and want to put a blow up version on the school mascot in the parking lot. They need to tie it down.
Jen’s rope is 7.8 m long and makes an angle of 360 with the ground. Holly’s rope is 5.9 m long. The wind is really strong so they will secure both ropes to the left of the mascot. How far to the nearest tenth of a metre, is Jen from Holly?
Answer:
2.6 m
Step-by-step explanation:
In the attached diagram
Consider Triangle ABC
[tex]\sin36^\circ =\dfrac{|BC|}{7.8} \\|BC|=7.8*\sin36^\circ\\|BC|=4.5847$ m[/tex]
Our goal is to determine the distance of Jen (at point A) to Holly (at Point D).
In Triangle ABC
[tex]\cos 36^\circ =\dfrac{|AC|}{7.8} \\|AC|=7.8*\cos36^\circ\\|AC|=6.3103$ m[/tex]
In Triangle BDC
Applying Pythagoras Theorem
[tex]|BD|^2=|BC|^2+|CD|^2\\5.9^2=4.5847^2+|CD|^2\\|CD|^2=5.9^2-4.5847^2\\|CD|^2=13.7905\\|CD|=\sqrt{13.7905}=3.7136$ m[/tex]
Now, |AC|=|AD|+|DC|
6.3103=|AD|+3.7136
|AD|=6.3103-3.7136
|AD|=2.5967
|AD|=2.6m (correct to the nearest tenth of a metre)
The distance of Jen from Holly is 2.6m.
express x in term of y:x/7+2y=6
Answer:
see explanation
Step-by-step explanation:
Given
[tex]\frac{x}{7}[/tex] + 2y = 6
Multiply through by 7 to clear the fraction
x + 14y = 42 ( subtract 14y from both sides )
x = 42 - 14y
6+1•4-3=? Can someone explain
Answer: 7
Step-by-step explanation:
1 x 4 = 4
6+4= 10
10-3=7

Rosanne is training for the Austin marathon, so she plans to run 10 miles in her neighborhood this weekend. It usually takes her an hour to run 6 miles. If she generally drinks 0.5 cups of water every 1 3 of an hour, how many cups of water will she drink on her run?
Answer:2.5 cups
Step-by-step explanation:
Given
Rosanne runs 6 miles in an hour
If she drinks 0.5 cups of water every [tex]\frac{1}{3}[/tex] of an hour
So in 1 hour Rosanne drinks 1.5 cups
So, for 6 miles Rosanne drinks 1.5 cups
i.e. For [tex]1\ mile \quad \equiv \quad \frac{1}{4}\ \text{cup}[/tex]
for [tex]10\ mile\quad \equiv \quad \frac{10}{4}\ \text{cup}[/tex]
[tex]=2.5\ \text{cup}[/tex]

The number i can be raised to whole number powers.
Look at the first four powers of i shown, and then use the drop-down menus to evaluate the expressions below.
Answer:
[tex]i^{8}=1[/tex] and [tex]i^{34}=-1[/tex] will be the answer.
Step-by-step explanation:
Since i = [tex]\sqrt{(-1)}[/tex]
i² = (-1)
[tex]i^{3}=-i[/tex]
[tex]i^{4}=(-1)^{2}[/tex] = 1
[tex]i^{8}=1^{2}[/tex] = 1
[tex](i^{8})^{2}=1[/tex]
[tex]i^{34}=[i^{17}]^2[/tex]
= [tex](i^{8}\times i^{8}\times i)^{2}[/tex]
= [1 × 1 × √(-1)]²
= 1² × 1² × [√(-1)]²
= (-1)
Therefore, [tex]i^{8}=1[/tex] and [tex]i^{34}=-1[/tex] will be the answer.
Jan says that a rhombus is a parallelogram and that every parallelogram is also a rhombus. Is Jan correct?
Part 2***
Explain why or why not.
Answer:
No
Step-by-step explanation:
Not all parallelograms are rhombuses, some parallelograms include rectangles, squares, hexagons, etc.
No. Jan is not correct. So, all parallelograms are not rhombuses.
What is a rhombus?A rhombus is a parallelogram because the opposite sides are parallel but every parallelogram is not a rhombus because all sides may not be equal. Every square is a rectangle because opposite sides are equal but not every rectangle is a square because all sides might not be equal. Every square is rhombus because all sides are equal but not every rhombus is a square because the angles might not be right angles.
here, we have,
We need to identify the properties of the given figure in order to answer why one figure can not be the other one:
A rhombus has all sides equal as well as parallel but all angles might not be right angles.
A square has all four sides equal and has 4 right angles.
A rectangle has equal opposite sides and 4 right angles.
A parallelogram has opposite parallel sides.
Hence, a rhombus can be a parallelogram because the opposite sides are parallel but every parallelogram can not be a rhombus because all sides may not be equal. Every square is a rectangle because opposite sides are equal but not every rectangle is a square because all sides might not be equal. Every square is rhombus because all sides are equal but not every rhombus is a square because the angles might not be right angles.
A parallelogram has opposite sides parallel and equal in length. Also, opposite angles are equal. Squares, rectangles, and rhombuses are all parallelograms. So all parallelograms are not rhombuses.
Not all parallelograms are rhombuses, some parallelograms include rectangles, squares, hexagons, etc.

Renu wants to put a border of lace around a rectangular table cover 4 m long and 2 m wide..
Find the length of the lace required for the table cover..
Answer:12m
Step-by-step explanation:
The length of the lace required will be the same as that obtained by calculating the perimeter of that table, so p= (L+W)×2
Hence, P=(4m+2m)×2
P= 12m
A figure is dilated by a scale factor of 3. If the origin is the center of dilation, what is the image of a vertex located at (3, 4)?
Answer:
(9,12).
Step-by-step explanation:
If a figure dilated by a scale factor of k and origin is the center of dilation, then the relation between point and its image is defined as
[tex]P(x,y)=P'(kx,ky)[/tex]
It is given that a figure is dilated by a scale factor of 3 and origin is the center of dilation. So,
[tex]P(x,y)=P'(3x,3y)[/tex]
We need to find the image of a vertex located at (3, 4). So, substitute x=3 and y=4 in the above rule of dilation.
[tex]P(3,4)=P'(3(3),3(4))[/tex]
[tex]P(3,4)=P'(9,12)[/tex]
Therefore, the image of a vertex located at (3, 4) is (9,12).
Answer: 9,12

4/8 +6/8 I just verfying the other person's. ok
Step-by-step explanation:
I did it on a calculator ;b
PLEASE MARK FallOutChild brainliest!!
Answer:
4/8 + 6/8 = 10/8 or 1 2/8, 1 1/4
Step-by-step explanation:
When it asks for like units, it's asking for the same denominator value. You can not add fractions together when they do not have a common denominator
if you multiply the denominator and numerator in 2/4 by 2, you get 4/8
Result of 4/8 + 6/8 gives you an improper fraction of 10/8

Find the approximate perimeter of polygon CODIFYCODIFYC, O, D, I, F, Y plotted below.
Round your final answer to the nearest hundredth.
please helppp
Answer:
49.81
Step-by-step explanation:
the formula I used is distance=[tex]\sqrt{(x_{2}-x_{1})+(y_{2}-y_{1})}[/tex]
Lets say we are finding the distance from c to y
c=(-6,9)
y=(5,9)
cy=[tex]\sqrt{(5-(-6))^{2}+(9-9)^2 }[/tex]
cy=[tex]\sqrt{(11)^2+(0)^2}[/tex]
cy=[tex]\sqrt{121+0}[/tex]
cy=[tex]\sqrt{121}[/tex]
cy=11
And you can find the distance between y and i, i and d, d and o, o and c, using the same formula.
After solving the distance of all I got
yi=16.55294536
id=1
do=9.219544457
oc=12.04159458
After you add them all up you get 49.8140844 which rounded to the nearest hundredth is 48.81.

A sine function can be used to model light waves. Green light has a wave length, or period of about 520 nm. Which equation best models green light?
A.) y=sin 260/pi theta
B.) y= sin pi/520 theta
C.) y= sin 520/pi theta
D.) y= sin pi/260 theta
Please help
Answer:
[tex] y = A sin (kx \pm wt)[/tex]
Where k represent the number of wave [tex]k =\frac{2\pi}{\lambda}[/tex] and [tex] w =\frac{2\pi}{T}[/tex] represent the angular frequency with T the period.
For this case we know tha T = 520 nm
And the angular frequency would be given by:
[tex] w = \frac{2\pi}{520}= \frac{pi}{260}[/tex]
So then the possible anwer for this case would be:
D.) y= sin pi/260 theta
Since is the only option with satisfy the general equation of a wave.
Step-by-step explanation:
Since the sine function can be used to model light waves we can use the following general expression:
[tex] y = A sin (kx \pm wt)[/tex]
Where k represent the number of wave [tex]k =\frac{2\pi}{\lambda}[/tex] and [tex] w =\frac{2\pi}{T}[/tex] represent the angular frequency with T the period.

A company rents water tanks shaped like cylinders. Each tank has a diameter of 8 feet and a height of 3 feet. The cost is $5 per cubic foot. How much does it cost to rent one water tank?
Answer:
$754.05
Step-by-step explanation:
We have to find the volume of one tank and multiply it by the cost of renting the tank per cubic foot.
The volume of a cylinder is:
[tex]V = \pi r^2h[/tex]
where r = radius
h = height
Each tank has a diameter of 8 feet (radius = 4 feet) and a height of 3 feet.
The volume of the tank is therefore:
[tex]V = \pi * 4^2 * 3 = 150.81 ft^3[/tex]
The cost of renting is $5 per cubic foot.
Therefore, the cost of renting a tank is:
150.81 * 5 = $754.05
It costs $754.05 to rent a tank.
A cube fish tank has a side length of 12 inches. What is the surface area of the fish tank, including the base and lid? Answer without units
Answer:
864
Step-by-step explanation:
Because the tank is a cube, all 6 faces have dimensions of 12 by 12. Therefore, the surface area is 6 * (12 * 12) = 864 (in²)
