A newly planted tree will be secured by wires, each attached to the ground 1.5 meters from the base of the tree. If each wire is 4 meters long, how high up the tree should each wire be attached, to the nearest tenth of a meter?
Answer:
3.7m
Step-by-step explanation:
The set up will form of right angled triangle with;
the length of the wires (the hypotenuse) = 4m
The base of the tree from the wire (adjacent) = 1.5m
The height of the tree(opposite ) = x
According to pythagoras theorem;
hyp² = opp²+adj²
4² = x²+1.5²
16 = x²+2.25
x² = 16 - 2.25
x² = 13.75
x = √13.75
x = 3.708
Hence the tree is 3.7m high (to the nearest tenth)

Ms. Ford is buying bundles of virgin hair from She’s Happy Hair that costs $75 per bundle, but $42.50 for shipping. If Ms. Ford spent $567.50 total, how many bundles of virgin hair did she buy?
Answer: 7 bundles.
Step-by-step explanation:
The cost per bundle is $75.
The cost for shipping is $42.50
She spent $567.50 in total.
The shipping is paid only one time, as all the bundles can be packaged togheter.
Then after paying the shipping, the left spent is:
$567.50 - $42.50 = $525
And each bundle costs $75, then the number of bundles that she bought will be equal to the number of times that we have $75 in $525. This is equal to the quotient between $525 and $75.
N = $525/$75 = 7
She bought 7 bundles

Yolanda found that her hair
grows .59 inches per month. It
started out at 7.5 inches long,
and she let it grow for 5 months.
Then, she cut 3.4 inches off. How
long is her hair now?
|86
Answer:
7.05 inches

h=7.5+2.95-3.4
h=10.45-3.4
h=7.05
A line contains the points (4,4) and (5,2). What is the equation of the line
that contains these two points?
Answer:y=-2/1x+12
Step-by-step explanation:
To find slope you need to use slope formula (y2-y1)/(x2-x1)
(2-4)/(5-4)
-2/1 is our slope
Now we need the y-int
Y=-2/1x+b
Take one of the given points and apply it to our equation
2=-2/1(5)+b
2=-10/1+b
2=-10+b
Add 10 to each side
12=b
Our final equation is
y=-2/1x+12
4x - 6 = 30 can you solve it
Answer:
x = 9
Step-by-step explanation:
take -6 to the other side so you add it to 30 = 36
equation is now 4x = 36
divide 4/4 and 36/4
x = 9
the solution to the equation 4x - 6 = 30 is x = 9
To solve the equation 4x - 6 = 30 and find the value of x, we can follow these steps:
1. Begin by isolating the term with the variable on one side of the equation. In this case, we want to isolate the 4x term. Add 6 to both sides of the equation:
4x - 6 + 6 = 30 + 6
4x = 36
2. To solve for x, divide both sides of the equation by 4:
(4x) / 4 = 36 / 4
x = 9
Therefore, the solution to the equation 4x - 6 = 30 is x = 9. When we substitute x with 9 in the equation, we have 4(9) - 6, which indeed equals 30. Thus, x = 9 satisfies the equation, and it represents the value that makes the equation true.

The sum of 28 consecutive odd positive integers is a perfect cube. Determine the smallest possible set? What is the first and last terms in the sequence. Plz helppp!
Answer:
71 + 73 + ..... + 125 = 2,744 = [tex]14^{3}[/tex].
Step-by-step explanation:
The smallest set starts at 71. The last term is 125.
The total is 2,744, which is [tex]14^{3}[/tex].
The smallest possible set is 71,73,75,....125. The first and last terms in the sequence is 71 and 125 respectively.
What is airthmatic sequence?Geometric sequence is the sequence in which the next term is obtained by adding or substracting the previous term with the same number for the whole series.
The sumation of airthmatic sequence is find out using the following formula.
[tex]S=\dfrac{n}{2}(a+l)[/tex]
Here, (a) is the first term of the sequence, (l) is the last term and (n) is the number of terms in sequence.
Let x is the first and the smallest term of the set. This set consists 28 consecutive odd positive integers. Thus, the sum of this set will be,
[tex]\sum=x+(x+2)+(x+4)+...+(x+54)\\\sum=28x+(2+4+6+....+54)\\\sum=28x+[\dfrac{27}{2}(2+54)]\\\sum=28x+756\\\sum=28(x+27)\\\sum=2\times2\times7(x+27)[/tex]
Now here 7 is prime number. The value of (x+27) should be perfect square of 7 and 2 to make it perfect cube. thus,
[tex]x+27=7^2\times2\\x=98-27\\x=71[/tex]
Put this value to find the sequence as,
[tex]71,71+2,71+4......,71+34\\71,73,75,.......125[/tex]
The first term in this set is 71 and last term is 125.
Hence, the smallest possible set is 71,73,75,....125. The first and last terms in the sequence is 71 and 125 respectively.

And the equation for slope is
m = (y2-y1)/(x2-x1)

A rope tied from a tent pole to a take in the ground forms 55 degrees angle with the ground. The pole is 3 feet from the stake, what is the length of the rope to the nearest tenth of a foot
Given:
A rope tied from a tent pole to a stake in the ground forms 55 degrees angle with the ground.
The pole is 3 feet from the stake.
To find:
The length of the rope to the nearest tenth of a foot.
Solution:
First draw a diagram according to the given information as shown below.
We know that, in a right angled triangle,
[tex]\cos \theta = \dfrac{Base}{Hypotenuse}[/tex]
In triangle ABC,
[tex]\cos 55^\circ=\dfrac{BC}{AC}[/tex]
[tex]0.573576=\dfrac{3}{AC}[/tex]
[tex]AC=\dfrac{3}{0.573576}[/tex]
[tex]AC=5.23034[/tex]
[tex]AC\approx 5.2[/tex]
Therefore, the length of the rope is 5.2 foot.

The answer is Distributive Property
Step by Step:
Your given equation is 7(w+6)+4
You are distributing 7 to w to get 7w, and 7 to 6, to get 42. The plus 4 stays the same because you don't have anything to distribute.
Addition, is obviously wrong, does 7 + 6 = 42? Multiplication is wrong. Sure you might be multiplying, but you are distributing to both numbers. And Commutative is DEFINITY wrong, because it has nothing to do with this situation

Answer:
The question is incomplete, so I looked for similar ones and found:
Of the 25 girls on the Alden Middle School soccer team, 40% also play on a travel team. How many of the girls on the middle school team also play on a travel team?
we can solve this the following way:
25 girls on the soccer team x 40% that play on a travel team = 10 girls form the soccer team that play on a travel team
we can also multiply (25 girls x 40) / 100 = 10 girls
we can check our work by:
10 girls / 40% = 25 girls in total
