PLEASE HELP a telegraph pole 7.5 metres high is held firm by a wire attached to its top and fixed to the ground 6.4 metres from the foot of the pole. how long is the wire? what is the angle of deviation?
Answer:
The flagpole is
4
meters tall.
Explanation:
The wire, the flagpole, and the ground make up the three sides of a triangle.
One angle of this triangle is given as
45
o
.
The angle of the flagpole with the ground must be
90
o
.
So the last angle must be
45
o
.
Because of the right angle
(
90
o
)
of the flagpole and the ground, this is a
right triangle
. The wire forms the hypotenuse.
Because both of the other angles are the same (both are
45
o
), this is an
isosceles
right triangle (the legs are equal.)
This particular kind of right triangle is called a
45

triangle, named for the degrees in its angles.

The sides

Maggie has $40 to buy a new dress and hair accessory for her school dance the dress she wants cost $35.75 the cost of her hair accessory is $2.80 does Maggie have enough money to purchase for the dress in the hair accessory Explain how can you use estimation to answer this question
Answer:
Yes Maggie has enough money to purchase the dress and hair accessory.
Step-by-step explanation:
Dress = $35.75
Hair accessory = $2.80
Total amount of money = $40
Does her have enough money?
Total Money in pocket - (Dress cost + hair accessory)
$40.00 - ($35.75 + 2.80)
$40.00 - ($36.00 + $3.00) Round to the nearest dollar
$40.00 - $39.00 = $1.00

Slope of the line that passes through (5,7) and (7,8)
Answer:
0.5
Step-by-step explanation:
To find the slope, you just have to do (y-y₁) / (x-x₁) where x and y are from the same point and x₁ and y₁ are from the same point. So just substitute in the values to get (7 - 8) / (5 - 7) which is -1 / -2 which is 1/2 or 0.5.

y ∝ x
=> y = kx
Comparing with line line of equation
y = mx + c
m = k , c = 0
Hence A proportional relationship must graph as a line
TRUE
at x = 0 , y = 0
Hence graph of a proportional relationship must pass through (0, 0).
TRUE
y = kx
=> y/x = k hence
Each point (or pair) in a proportional relationship must share the same ratio.
Each point (or pair) in a proportional relationship must share the same difference.
The division problem below is being solved using long division. Use what you know about division to figure out the mystery divisor, then describe how you found it.
The mystery divisor to the question based on the information given is 18.
How to determine the divisor?Dividing the first dividend 4 by the unknown divisor x and getting the first number 2 in the quotient and when the quotient 2 is multiplied by the divisor gives 36, so definitely, 4 cannot be used
Using 40 as the dividend, 40 divided by the divisor x gives 2 as the first quotient. And the first quotient 2 multiplied by the divisor x gives 36.
And to interpret this, 2x=36
Dividing through by 2x=36
x = 36/2
x = 18
So, the divisor is 18

Answer:
x = 36°, 2x° = 72°, 3x° = 108°, and 4x° = 144°
Step-by-step explanation:
Given the quadrilateral in which the sum of its four angles is 360°.
We can establish the following formula to find the value of x, and determine the measures of each angle:
x° + 2x° + 3x° + 4x° = 360°
Combine like terms:
10x° = 360°
Divide both sides by 10 to solve for x:
[tex]\mathsf{\frac{10x^{\circ}}{10}\:=\: \frac{360^{\circ}}{10}}[/tex]
x = 36°
Substitute the value of x into each unknown angle measures:
x = 36°
2x° = 2(36)° = 72°
3x° = 3(36)° = 108°
4x° = 4(36)° = 144°
Verify whether the sum of the previously unknown angle measures equal 360°:
x° + 2x° + 3x° + 4x° = 360°
36° + 72° + 108° + 144° = 360°
360° = 360° (True statement).
Therefore, the following are the angle measures of the given quadrilateral: x = 36°, 2x° = 72°, 3x° = 108°, and 4x° = 144°

Step-by-step explanation:
The y coordinate of the vertex of f (x)=-x^2+8x+7 is f(4)
Hello there.
To answer this question, we need to remember some properties about the vertex of quadratic functions.
Let [tex]f(x)=ax^2+bx+c,~a\neq0[/tex]. Its vertex can be found on the coordinates [tex](x_v,~y_v)[/tex] such that [tex]x_v=-\dfrac{b}{2a}[/tex] and [tex]y_v=-\dfrac{b^2}{4a}+c[/tex], in which [tex]y_v=f(x_v)[/tex].
Using the coefficients given by the question, we get that:
[tex]x_v=-\dfrac{8}{2\cdot(-1)}\\\\\\ x_v=-\dfrac{8}{-2}\\\\\\ x_v=4[/tex]
Thus, we have:
[tex]y=f(x_v)=f(4)[/tex]
So the statement is true, because the [tex]x[/tex] coordinate of the vertex of the function is equal to [tex]4.~~\checkmark[/tex]

Step-by-step explanation:
Realize that:
speed = distance / time and thus
time = distance / speed
Then the whole journey of 40/60 hours is the sum of (let's call them t1 and t2)
cycling: t1 = 2/y hours
running: t2 = 4/(y-4) hours
so we must simplify t1+t2=40 minutes (a.k.a. 4/6 hours):
2/y + 4/(y-4) = 4/6
let's multiply the first term by (y-4)/(y-4) and the second term by (y/y):
[tex]\frac{2(y-4)}{y(y-4)} + \frac{4y}{y(y-4)} = \frac46[/tex]
since they now share a common denominator:
[tex]\frac{2(y-4) + 4y}{y(y-4)} = \frac46[/tex]
[tex]\frac{6y-8}{y(y-4)} = \frac46[/tex]
cross-products:
[tex]6 (6y-8) = 4y(y-4)[/tex]
further simplification:
[tex]36y - 48 = 4y^2 - 16y[/tex]
[tex]4y^2 - 52y + 48 = 0[/tex]

Step-by-step explanation:
For this problem you need to find 3/4 of 18. 18x3/4 = 54/4, or 13.5
The total number of miles Steve's family traveled is 24 miles.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, Steve's family traveled 3/4 the distance that Mike's family traveled.
Let the total number of miles Steve's family traveled be x.
Now, 3/4 ×x=18
3x=72
x=72/3
x=24 miles
Therefore, the total number of miles Steve's family traveled is 24 miles.

What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
