Step-by-step explanation:
Given
The attached triangle
Required
Find VW
To find VW, we make use of the following equivalent ratios.
[tex]YX : XW = ZX : XV[/tex]
Where:
[tex]YX = ZX - ZY = 42 - 28 = 14[/tex]
[tex]XV = XW + VW = 25 + VW[/tex]
So, we have:
[tex]14 : 25 = 42 : 25 + VW[/tex]
Express as fraction
[tex]\frac{14 }{ 25 }= \frac{42 }{ 25 + VW}[/tex]
Divide both sides by 14
[tex]\frac{1}{ 25 }= \frac{3}{ 25 + VW}[/tex]
Cross multiply
[tex](25 + VW) * 1 = 3 * 25[/tex]
[tex]25 + VW = 75[/tex]
Solve for VW
[tex]VW = 75 -25[/tex]
[tex]VW = 50[/tex]
What is the area of the triangle?
show me process
Answer:
area = 30
Step-by-step explanation:
You would want to use the formula for a right triangle to find the area.
Right triangle formula = a * b/ 2 will give you the area.
So, 5*12 = 60, 60/2 = 30.

If the volume of the box is 112 in3, find the value of x (in inches). (Assume that all the dimensions in the figure are in inches.)
Answer:
X=4
Step-by-step explanation:
4x(x+3)=112
4x^2+12x=112
x^2+3x=28
x^2+3x-28=0
(X+7)(x-4)=0
X=-7 or x=4
Answer:
volume of cuboid =l×b×h
112in³=(x+3)×x×4
112in³/4=x²+3x
28=x²+3x
x²+3x-28=0
x²+7x-4x-28=0
x(x+7)-4(x+7)=0
(x+7)(x-4)=0
either
x=-7(rejected length or breadth or height will be always positive)
or
x=4in

Find the value of x in the triangle shown below 6 2
The value of x in the stated triangle is 6.32 based on given dimensions.
The stated triangle is right angled triangle and hence will follow Pythagoras theorem. The calculation will be done using the Pythagoras formula as stated -
Perpendicular² = Base² + Height²
Keep the values in formula to find the value of x
x² = 2² + 6²
Taking square on the Right Hand Side of the equation
x² = 4 + 36
Add the digits on Right Hand Side of the equation
x² = 40
x = ✓40
Taking square root
x = 6.32
Hence, the length of x is 6.32.

I will gove brainlist ..The line graph shows the amount of water loss in a leaking tank during 7 hours.The owner pays $1for every 8 liters of water lost.How much will he have to pay after 2 hours
Answer:
The owner will have to pay $ 125 after 2 hours.
Step-by-step explanation:
Given that the line graph shows the amount of water loss in a leaking tank during 7 hours, and the owner pays $ 1 for every 8 liters of water lost, to determine how much will he have to pay after 2 hours the following calculation must be performed :
((6000 - 5000) / 8) x 1 = X
(1000/8) x 1 = X
125 x 1 = X
125 = X
Therefore, the owner will have to pay $ 125 after 2 hours.

Answer:
each tangent is 20.785 ft long
Step-by-step explanation:
since the tangent forms a right angle with the radius, and a line from P to O bisects the 60° angle:
tan 30° = 12/x
0.5774 = 12/x
0.5774x = 12
x = 20.785 ft

2x²+7x-4
Answer:
2x² + 7x - 4
Step-by-step explanation:
(2x + 1)(x + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(x + 4) - 1 (x + 4) ← distribute parenthesis
2x² + 8x - x - 4 ← collect like terms
= 2x² + 7x - 4
A survey was given to people who own a certain type of car. What percent of the people surveyed were completely satisfied with the car?
Answer:
65 percent
Step-by-step explanation:
The solution is 65 %
The percentage of people who were satisfied with the car is 65 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the percentage of people who were satisfied with the car be = P
Now , the number of people who were satisfied with the car = 1625
The number of people who were somewhat satisfied with car = 665
The number of people who were not satisfied with the car = 210
The total number of people surveyed = number of people who were satisfied + number of people who were somewhat satisfied + number of people who were not satisfied
Substituting the values in the equation , we get
The total number of people surveyed = 1625 + 665 + 210
The total number of people surveyed = 2500 people
So , the percentage of people who were satisfied with car P = number of people who were satisfied with the car / total number of people surveyed
Substituting the values in the equation , we get
Percentage of people who were satisfied with car P = ( 1625 / 2500 ) x 100
Percentage of people who were satisfied with car P = 0.65 x 100
Percentage of people who were satisfied with car P = 65 %
Therefore , the value of P is 65 %
Hence , the percentage is 65 %

A physical trainer has four workouts that he recommends for his clients. The workouts have been designed so that the average maximum heart rate achieved is the same for each workout. To test this design he randomly selects twenty people and randomly assigns five of them to use each of the workouts. During each workout, he measures the maximum heart rate in beats per minute with the following results.
Maximum Heart Rates (Beats per Minute)

The null hypothesis is : [tex]$u_1=u_2=u_3=u_4$[/tex]
Alternative hypothesis : At least one of the [tex]$u$[/tex] is not equal.
The significance level = 0.05
Analyzing the sample data:
F statistics is given by :
[tex]$F=\frac{MSB}{MSE}$[/tex]
= 2.97
[tex]$F_{critical}=3.24$[/tex]
The P-value= 0.06
The result : Since the P-value of 0.06 is greater than the significance level (0.05), hence we fail to reject the null hypothesis.
So we cannot conclude that there is no difference between the average maximum heart rates that are achieved during the four workouts.

If a line goes through the point (2, 7) and has a slope of -2, what is the equation of the line?
Answer:
y = -2x + 11
Step-by-step explanation:
Slope point equation:
y - y1 = m(x -x1)
y1 = 7 ; x1 = 7 , m = -2
y - 7 = -2(x - 2)
y - 7 = -2x -2*(-2)
y -7 = -2x + 4
y = -2x + 4 + 7
y = -2x + 11

Alternate exterior angles are congruent.
Which angle forms a pair of alternate
exterior angles with angle 1?
Answer:
<1 = <8
Step-by-step explanation:
An angle that will form a pair of alternate exterior angles with <1 will be the angle that is found outside of the parallel lines but on the opposite side of the transversal that cuts across the two parallel lines.
<8 is an exterior angle, and also is alternate angle to <1. It forms a pair of alternate exterior angles pair with <1.
Therefore, <1 = <8
