GEOMETRY HELP PLEASE!! WILL MARK BRAINLEIST!
4
Answer:
5.7 unit
Step-by-step explanation:
From the question,
Applying pythagoras theorem,
a² = b²+c²....................... Equation 1
From the diagram.
a = /QX/, b = /XR/, c = /RQ/
Given: b = /XR/ = 4 units, c = /RQ/ = 4 units.
Substitute these values into equation 1
a² = 4²+4²
a² = 16+16
a² = 32
a = [tex]\sqrt{32}[/tex]
a = 5.7 units
Hence, QX = 5.7 units
Questions 7 and 8 please. Really need help thank you!!
Answer:
7) sin 60° = 25√3/Z
0.8660 = 25√3/Z
Z = 50
8) using the Pythagorean theorem:
50² = (25√3)² + y²
2500 = 1875 + y²
y² = 625
y = 25
Answer:
z = 50
y = 25
Step-by-step explanation:
Using the 30, 60, 90 triangle rule
you can figure this out.
The rule says
With a 30, 60, 90 triangle
Given the shorter leg, (side across the 30 degree angle,
To find longer leg (side across the 60 degree angle):
Multiple shorter leg by radical 3.
To find hypotenuse (side across the 90 degree angle):
Multiple shorter leg by 2.
Thus
Shorter leg (side opposite 30 degree): 25
Longer leg (side opposite 60 degree):
25 radical 3
Hypotenuse(side opposite 90 degree): 50
Can someone please solve this, can you please show your work.
x - 4 = -3
Step-by-step explanation:
We need to find x in this question.
x - 4 = -3
So, shifting -4 from one side to another, we get:-
x = -3 + 4
[+4 because the sign changes when we replace the numbers]
x = 4 - 3
x = 1 is the required answer.
Hope it helps :)
Find the final hourly wage if a $10.50 starting wage is increased by 6% each year for 7 years.
Answer:
In seven years the hourly rate will be $15.79.
Step-by-step explanation:
Giving the following information:
Hourly rate= $10.5
Number of periods= 7 years
Increase rate (i)= 6%
To calculate the hourly rate in 7 years, we need to use the following formula:
FV= PV*(1 + i)^n
FV= 10.5*(1.06^7)
FV= $15.79
In seven years the hourly rate will be $15.79.
What is the approximate area of Nevada?

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]
Actually Welcome to the concept of Areas,
Let's divide the above map in to 2 parts , that is a rectangle and a triangle, and add both thier areas to get the area of the Nevada.
so we get as,
Area of triangle = 1/2*b*h
Area of triangle ==> 1/2*309*306 ==> 47277 mi^2
Area of rectangle = l*b = 205*309 ==> 63345 mi^2
Area of NEVADA = 47277 + 63345 = 110622 mi^2
hence the area = 110622 mi^2
Answer:
the approximate area of Nevada is 110,567 mi²

Answer:
1. 8.19, 2. 25.96, 3. 3.95
Step-by-step explanation:
use soh cah toa
1. cos is adjacent/hypotenuse
cos73=x/28
multiply both sides by 28
28cos73=x=8.186
2. sin is opposite over hypotenuse
sin68=x/28
multiply both sides by 28
28sin68=x=25.961
3. sin is opposite over hypotenuse
sin26=x/9
myltiply both sides by 9
9sin26=x=3.945

Rahim was asked to make p the subject of this formula
Q = 5/3 -7
He started his answer as follows
3Q = p - 21 hence p =
Complete Rahim's final answer.
Answer:
p = 63
Step-by-step explanation:
3Q = p - 21
transfer the -21 to the left as the value of Q. Since it was negative, when we transfer it to the left it will turn to poditve so,
3(21) = p
multiply 3 and 21 so 3 multiplied by 21 is equal to,
63 = p, then the answer is p = 63

Write an equation of the line with a slope of −7 and y-intercept of 1.
Answer:
y = -7x + 1
Step-by-step explanation:
Remember the formula for slope-intercept form: y = mx+ b
m is equal to the slope value
b is equal to the y-intercept value
Meaning, when you substitute the values in, you get:
y = -7x + 1
Answer:
y = -7x - 1 is the desired equation.
Step-by-step explanation:
Choose the form of the equation of a straight line that requires the least amount of work. In this particular case we are given the slope (-7) and the y-intercept (1), and so use the slope-intercept form y = mx + b:
y = -7x - 1 is the desired equation.

x=1200/10=120
again
45% of x=54
x=5400/45=120

can you figure out the missing number in this sequence?
2, 5, 9, 14, 27
Answer:
The missing number in the sequence is 20
Step-by-step explanation:
The difference between the numbers are as follows: 3,4,5,6,7
The missing number of the given sequence is 13.
The given sequence is,
2, 5, 9, 14, 27
We can see that the difference between each consecutive number is increasing.
The difference between 2 and 5 is 3,
The difference between 5 and 9 is 4,
The difference between 9 and 14 is 5,
And the difference between 14 and 27 is 13.
Therefore, it's possible that the next number in the sequence could have a difference of 14 or more.
So,
To determine the missing number,
We can look at the pattern of the differences between the numbers in the sequence.
Since the difference between 14 and 27 is 13,
We can assume that the difference between the missing number and 27 is at least 14.
Therefore, we can subtract 14 from 27 to get our missing number, which is 13.

the diagram shows a door that has a window in it. the front faces of the door and the window are similar rectangles the dimensions shown. what is the height of the window in centimeters?
Answer:
Step-by-step explanation:
One of the measures of a triangle is 30º. If the sum of the other 2 angles is 150º and the differnce their measures is 18º what are the of the unkown angles
Answer: 84° & 66°
Step-by-step explanation:
find our variables...
difference in two unknown angles is 18 so...
Let's use a, b, & c to set up
a=30 b=b c=b-18
150=b+c
150=b+(b-18)
150=2b-18
168=2b
84=b
Use our known b to find c...
c=b-18
c=84-18
c=66
Adding all three up to make sure they give us 180 degrees is a good way to check our work.
a+b+c=
30+84+66=180

Step-by-step explanation:
Find the areas of the sectors formed by ∠DFE. Round your answers to the nearest hundredth.
Answer:
Area of sector DFE = 177.79cm²
Area of sector DGE = 437.65cm²
Step-by-step explanation:
Find the diagram attached;
Area of the sector is expressed according to the formula;
Area of the sector = theta/360 * πr²
theta is the central angle = 360 - 256
theta = 104°
r is the radius = 14cm
Substitute into the formula as shown;
Area of the sector = theta/360 * πr²
Area of the sector DFE = 104/360 * 3.14(14)²
Area of the sector DFE = 0.289 * 615.44
Area of the sector DFE = 177.79cm²
Hence the area of the sector <DFE to the nearest hundredth is 177.79cm²
For sector DGE:
Area of the sector DGE = 256/360 * 3.14(14)²
Area of the sector DGE = 0.7111 * 615.44
Area of the sector DGE = 437.65cm²
Hence the area of the sector <DGE to the nearest hundredth is 437.65cm²

Some one help me solve for x
Answer:
x = 10
Step-by-step explanation:
The sum of the interior angles of a quadrilateral = 360°
Sum the angles and equate to 360
9x + 15 + 85 + 90 + 80 = 360, that is
9x + 270 = 360 ( subtract 270 from both sides )
9x = 90 ( divide both sides by 9 )
x = 10
