Answer:
-17/3
-5.666667
Step-by-step explanation:
Assuming GH≅BC
You can write this equation to represent the problem:
[tex]7z-1=4z-3[/tex]
Then, just solve for z:
[tex]7z=4z-3+1\\7z-4z=-2\\3z=-2\\z=-\frac{2}{3}[/tex]
Now, plug that back into GH:
[tex]7(-\frac{2}{3})-1\\\\-\frac{14}{3}=1\\\\-\frac{17}{3}[/tex]
Thats -17/3, or -5.666667

8. Denise using a ladder to clean the outside of her second story windowsThe ladder she is using is 34 feet long , and she puts the base of the ladder 15 feet away from the houseHow high up the side of her house does the ladder reach Round to the nearest tenth , If necessary
Answer:
30.5 ft
Step-by-step explanation:
Right triangle: a^2 + b^2 = c^2
15^2 + x^2 = 34^2
225 + x^2 = 1,156
x = sqrt (1156 - 225)
x = 30.5 ft
2n+3pm=7px solve for x
Answer:
x is being multiplied by 7p so to find x you need to have it alone on one side of the problem, so you could divide both sides by 7p, making it look like 2n+3pm/7p=x (simplify if needed)

a line has a y-intercept on -11 and a slope of .25. Write it's equation in slope intercept form
Answer:
[tex]y = \frac{1}{4} x - 11[/tex]
Step-by-step explanation:
Slope- intercept form
y= mx +c, where m is the slope and c is the y-intercept.
Slope
= 0.25
= ¼
Substitute m= ¼ into the equation:
y= ¼x +c
Given that the y-intercept is -11, c= -11.
Thus, the equation of the line is y= ¼x -11.

Find the values of a and b that make each equation true.
1) 3 – 36i = 9a + 4bi
2) a – 15i = -7 – (2b-3)i
Step-by-step explanation:
1) 3 – 36i = 9a + 4bi
3 = 9a => a = 3/9 = ⅓
-36 = 4b => b = -36/4 = -9
2) a – 15i = -7 – (2b-3)i
a = -7
-15 = -(2b-3)
2b-3 = 15
2b = 18
b = 18/2= 9

can someone tell me the answer to. 16 = 2(2x + 4)
Answer:
16= 4x+8
16-8=4x
x=8/4
x= 2
Step-by-step explanation:
16=2(2x+4) 16=(2×2x) + (4×2) 16= 4x+8. 16-8=4x+8-8. 8=4x. 8/4=4x/4. 2=x

Which proportion can be used to find 65% of 90?
Answer:
The proportion which represents the 65% of 90 is:
Step-by-step explanation:
Given information:
We need to find the proportion that can be used to find
65% of 90
Let us take :
% of
So,
Hence , the proportion which represents the 65% of 90 is
Answer:
The proportion [tex]\frac{65}{100} = \frac{x}{90}[/tex]
Step-by-step explanation:
[tex]\frac{65}{100} = \frac{x}{90}[/tex]
(65)(90) = 100x
5850/100 = x = 58.5
58.5 = 65% of 90
Alternatively, you can use the more direct approach:
[tex]\frac{65}{100} (90)[/tex]
= [tex]\frac{65 * 9}{10}[/tex] = 585/10 = 58.5
Point (-1,3). m= Undefined.
Find the equation of the line that contains the given point and has the given slope.
And explain..
Answer:
m=1/0 (undefined)
equation=y2-y1/x2-x1=y-y1/x-x1
since M is undefined and M=y2-y1/x2-x1
then the equation=y-y1/x-x1=1/0
y-3/x--1=1/0
cross multiplying
0 (y-3)=1 (x+1)
=x+1

what is the value of x?
Answer:
x = 51°
Step-by-step explanation:
The image of the triangle is an isosceles triangle. Since it is an isosceles triangle, ∠DFE = ∠FDE.
78 + x + x = 180
=> 2x = 102
=> x = 51°

what is the 6th term for 16,48,144
Answer:
Step-by-step explanation:
16, 48 , 144 ...... is a geometric sequence.
first term = a = 16
common ratio = r = 2 term ÷ first term = 48 ÷ 16 = 3
nth term = [tex]ar^{n-1}[/tex]
[tex]6th \ term = 16 * (3)^{6-1}\\\\\\= 16 * 3^{5}\\\\= 16 * 243\\\\= 3888[/tex]
A balloon with a 50 ft string makes an angle of 39 degrees with the ground. How high above the ground is the balloon if the land of the person holding the balloon is 5 ft above the ground?
Answer:
Step-by-step explanation:
This is late but the other is not an answer at all.
The 50 ft string makes an angle of 39 degrees with the ground so the stromg and balloon form a right-angle triangle to the ground.
The height of balloon from string = 50*sin(39degrees)
= 31.47 ft
As the string is held by a person 5 ft above ground, the balloon is above ground at 31.47 + 5
= 36.47 ft.
graph the equation on the coordinate plane. y = 4x
The graph of the equation, y = 4x, is shown below.
How to Graph an Equation on a Coordinate Plane?Given an equation, for example, y = 4x, to plot it on a coordinate plane, we need to find the coordinates of the line that we would plot and connect together to graph the equation.
Find the corresponding y-values when x = 1, x = 2, and x = 3. To do this, see the steps below:
Substitute x = 1 into y = 4x:
y = 4(1)
y = 4
We have a point, (1, 4).
Substitute x = 2 into y = 4x:
y = 4(2)
y = 8
We have another point, (2, 8).
Substitute x = 3 into y = 4x:
y = 4(3)
y = 12
We have a third point, (3, 12).
Plot the three points on a coordinate plane as shown below to get the graph of the equation.
