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]
[tex]y^2 - 13y + 12 = 0[/tex]

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
Yes
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]

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

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

)
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

), this is an
isosceles
right triangle (the legs are equal.)
This particular kind of right triangle is called a

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°

Ally is given three different sums of the same sequence to calculate. If she completes the three problems in order do the sums increase or decrease in value. Why? A) The sums decrease in value because you are subtracting. B) The sums increase in value because even though you are multiplying and adding. There is no subtraction or division. C) The sums increase in value because even though you subtract 7 from each term you are still increasing the positive number that is being multplied so they will increase. D) The sums decrease in value because even though you are increasing the positive number that is being multplied you have to subtract 7 from each answer so they will decrease.
If Ally is given three different sums of the same sequence to calculate, and she completes the three problems in order C) The sums increase in value because even though you subtract 7 from each term you are still increasing the positive number that is being multiplied so they will increase.
The sums will not decrease in value because there is no subtraction. They will not increase in value because of multiplication or addition. The sums will not decrease in value because of the subtraction of 7 from each answer.
Thus, the sums will increase in value because of the increasing positive number that is being multiplied.

Step-by-step explanation:
Given : Statement about proportional relationships
To Find : Which statement is False
Solution:
proportional relationships
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.

120-10=11x
110=11x

6(10)-1=59
Answer:
m<H = 59°
Step-by-step explanation:
Use the theorem on the measure of an exterior angle of a triangle.
5x + 17 + 6x - 1 = 126
11x + 16 = 126
11x = 110
x = 10
m<H = 6x - 1
m<H = 6(10) - 1
m<H = 60 - 1
m<H = 59°

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.

Height from angle A = 3 x
Hypotenuse of triangle = 5 x
By Pythagoras Theorem
Hypotenuse^2 = height^2 + base^2

cos^2 A = 1 - 9 / 25
cos^2 A = ( 25 - 9 ) / 25
cos^2 A = 16 / 25
