Answer:
Step-by-step explanation:
we know that UPR is a straight line so QPR and QPU equals 180 degrees
since we have QPR already we just have to do 180 - 70 = 110
so 110 is our answer

A tree has a shadow 900 inches long. At the same time of day, Evelyn's shadow is 72 inches long. The two triangles formed by the tree, Evelyn, and their shadows are similar right triangles, as shown in the diagram below.
Evelyn is 65 inches tall. What is the height of the tree in inches?
Answer:
812.5 inches
Step-by-step explanation:
Turn these numbers into fractions:
[tex]\frac{h}{900} \frac{65}{72}[/tex]
Solve 900/72 to get 12.5. This means that multiplying 72 x 12.5, you get 900. So, to find the height of the tree: h you multiply 65 x 12.5. Your answer to this is 812.5.
Hope it helps!

What are the values of r and a1 for 1/4(2)k-1
Given:
[tex]\sum_{k=1}^{6}\dfrac{1}{4}(2)^{k-1}[/tex]
To find:
The values of r and [tex]a_1[/tex].
Solution:
We have,
[tex]\sum_{k=1}^{6}\dfrac{1}{4}(2)^{k-1}[/tex]
Here,
[tex]a_k=\dfrac{1}{4}(2)^{k-1}[/tex] ...(i)
We know that, kth term of a GP is
[tex]a_k=a_1(r)^{k-1}[/tex] ...(ii)
From (i) and (ii), we get
[tex]a_1=\dfrac{1}{4}[/tex] and [tex]r=2[/tex]
Therefore, the correct option is C.
Answer:
c

The measure angle of 3
Answer:
69
Step-by-step explanation:
X is 13 cause of the corresponding angles when you solve and then 3 is supplemebntary so 180-111 is 69
Answer:
69
Step-by-step explanation:
180 - 111 = 69
Find the value of X in the diagram above
Answer:
17
Step-by-step explanation:
for L to be parallel to M the two angles have to be supplementary so to add up to 180°
6x+8+4x+2 =180
10x+10 =180
10x = 180-10
10x = 170
x=170/10
x=17
5. Please write the equation of a line in y=mx+b format. Find the SLOPE first then find the Y-INTERCEPT (b) Your answer
Answer:
y = [tex]\frac{5}{3}x-1[/tex]
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here m = slope of the line
b = y-intercept
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the graph attached,
Since, the given line passes through (0, -1) and (3, 4),
Slope 'm' = [tex]\frac{4+1}{3-0}[/tex]
m = [tex]\frac{5}{3}[/tex]
y - intercept 'b' = -1
Therefore, equation of the line will be,
y = [tex]\frac{5}{3}x-1[/tex]
A function, f(x) = x, is vertically translated 4 units up and then reflected across the y-axis. What's the new function in terms of g(x)?
Answer:
The new function is g(x) = -x + 4
Step-by-step explanation:
If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k If the function f(x) reflected across the y-axis, then its image is g(x) = f(-x)∵ A function f(x) = x
∵ It is vertically translated 4 units up
→ By using the 1st rule above, the value of k = 4
∴ k = 4
∵ Its image h(x) = f(x) + k
∴ Its image h(x) = f(x) + 4
∴ Its image h(x) = x + 4
∵ Then it is reflected across the y-axis
→ By using the 2nd rule above, change the sign of x in h(x)
∵ h(x) = x + 4
∴ g(x) = h(-x)
∴ g(x) = -x + 4
∴ The new function is g(x) = -x + 4

Step-by-step explanation and Answer:
1: 2x+6=96 => x = 45
2: 2x+3+x-6=180 => x = 39
3: x+4+3x+2=90 => x = 21
4: x+16=4x-5 => x = 7
5: 2x+20+x+40=180 => x = 40
6: 7x-9+4x=90 => x = 9

Answer:
heres the graph
Step-by-step explanation:
1. Which would be a more helpful for solving the system: adding the two equations or subtracting
one from the other? Explain your reasoning.
2. Solve the system without graphing. Show your reasoning.
2x+1/2y=7
6x-1/2y=5
Answer:
1) Subtracting one from the other
2) x = 0.375 and y = 0.125
Step-by-step explanation:
Equation 1 :
[tex]\frac{2x+1}{2y}=7\\\\[/tex]
Equation 2:
[tex]\frac{6x-1}{2y}=5[/tex]
To solve these equations by the Elimination method we multiply equation 1 with 6 and multiply equation 2 with 2 so now,
[tex]\frac{2x+1}{2y} =7\\\\2x+1=14y\\\\Multiplying\ Equation\ 1\ with\ 6\\\\12x+6=84y[/tex]
Now for the second equation:
[tex]\frac{6x-1}{2y}=5\\\\6x-1=10y\\\\Multiplying\ equation\ 2\ with\ 2 \\\\12x-2=20y[/tex]
Now subtracting equation 2 from equation 1
[tex]12x+6=84y\\\\12x-2=20y\\\\Subtracting\ leads\ to\\12x-12x+6-(-2)=84y-20y\\0+8=64y\\8=64y\\8/64=y\\0.125=y[/tex]
now insert this value of y into any equation
lets insert it into equation 1
[tex]\frac{2x+1}{2y} =7\\\\2x+1=14y\\2x+1=14(0.125)\\2x+1=1.75\\2x=1.75-1\\2x=0.75\\x=0.75/2\\x-0.375[/tex]
what is 0.13095238095 as a fraction
Answer: 13095238095/100000000000
Step-by-step explanation: To write 0.13095238095 as a fraction you have to write 0.13095238095 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
0.13095238095 = 0.13095238095/1 = 1.3095238095/10 = 13.095238095/100 = 130.95238095/1000 = 1309.5238095/10000 = 13095.238095/100000 = 130952.38095/1000000 = 1309523.8095/10000000 = 13095238.095/100000000 = 130952380.95/1000000000 = 1309523809.5/10000000000 = 13095238095/100000000000
