Answer:
95°
Step-by-step explanation:
Well first draw a parallel to p, let's say r
so we have that
[tex]\angle 2+\angle3=\angle1[/tex]
and
[tex]\angle y=148\\\\\angle x +63=180\\\\\angle x=117[/tex]
so now by internal angles of parallels we know that
[tex]\angle x +\angle 2 = 180\\\\\angle y +\angle 3 = 180[/tex]
which is
[tex]117+\angle 2 = 180\\\\\longrightarrow \angle 2 = 63\\\\148+\angle 3 = 180\\\\\longrightarrow \angle3=32[/tex]
so
[tex]\angle 1 = 63+32\\\\\angle 1 = 95[/tex]
Pedro drives the same route to work on Monday through Friday. His route includes one traffic light. According to the local traffic department, there is a 55% chance that the light will be red when he arrives at the intersection on a randomly selected workday. Suppose we choose 10 of Pedro's workdays at random and let Y = the number of times that the light is red.
Answer:
6 days
Step-by-step explanation:
Given
The proportion can be represented as:
[tex]p = 55\%[/tex]
And the number of days can be represented as:
[tex]n = 10[/tex]
Required
Determine the expected number of times, the light is red
To do this, we simply multiply the proportion by the number of days:
[tex]Y = n * p[/tex]
Substitute values for n and p
[tex]Y = 10 * 55\%[/tex]
Convert percentage to decimal
[tex]Y = 10 * 0.55[/tex]
[tex]Y = 5.5[/tex]
Approximate
[tex]Y = 6[/tex]
Hence, the expected number of days is 6 days
Determine whether the function is linear or nonlinear. Explain
helppppppppp
Answer:
A linear function follows a constant rate of change Here we see x moves by 4 units and that y decreases by 4 units then suddenly changes to 6 units hence 13 Is Not A functionFor 12, it is a function because it follows a consistent rate of change which is x or one unit of change.Answer:
12) The function is linear.
13) This function is not linear.
Step-by-step explanation:
13) A linear functions equation must be in y = mx + b form
When you graph the table there is no y = mx + b equation that makes a line that passes through all the points.

3(x + 2) = 2x + 14
How many solutions
Answer:
I solution; x=8
Step-by-step explanation:
You have to solve for x by simplifying both sides of the equation and then isolating the variable
3(x+2)= 2x+14
Distributive Property
3x+6=2x+14
Isolate the variable
3x+6-6=2x+14-6 which is 3x=2x+8
3x-2x=2x-2x+8
x=8
how many solutions does y=5x+3 have
Answer:
infinite
Step-by-step explanation:
y and x can be any numbers because they're independants
Answer:
[tex]\infty[/tex]
Step-by-step explanation:
The domain/range of [tex]x[/tex] or [tex]y[/tex] is not restricted. Therefore, for [tex]x \in \mathrm{R}[/tex], the solutions for [tex]y[/tex] are [tex]\mathrm{R}[/tex] (all real numbers).
Therefore, there are an infinite number of solutions to this equation.

PLEASE HELP! Brainliest and points!!!!
Answer:
RS = 47 units
Step-by-step explanation:
The midsegment is half the sum of the parallel bases, that is
3x + 5 = [tex]\frac{1}{2}[/tex] ( 2x + 15 + 6x - 37)
3x + 5 = [tex]\frac{1}{2}[/tex] (8x - 22) = 4x - 11 ( subtract 4x from both sides )
- x + 5 = - 11 ( subtract 5 from both sides )
- x = - 16 ( multiply both sides by - 1 )
x = 16
Thus
RS = 2x + 15 = 2(16) + 15 = 32 + 15 = 47

The perimeter of the base of a square pyramid is 40 feet. The slant height of the pyramid is 12 feet. Find the surface area of the pyramid.
SHOW WORK
9514 1404 393
Answer:
340 ft^2
Step-by-step explanation:
The length of one side is 1/4 of the perimeter, so is 10 ft.
The area of the base is the square of the length of the side:
base area = (10 ft)^2 = 100 ft^2
__
The lateral area is the area of four triangles, each with a base of 10 ft and a height of 12 ft.
lateral area = 4(1/2)(10 ft)(12 ft) = 240 ft^2
__
The total surface area is the sum of the base area and the lateral area:
surface area = base area + lateral area
surface area = (100 ft^2) +(240 ft^2) = 340 ft^2

Answer:
1a) 67.2 kg
1b) 66.5 kg
1c) 64 kg, 68 kg
2a) Mean = 58.1m, Median = 55m, Mode = 49m
2b) The mode is not a good measure since all data except 49m appeared twice i.e. the data set is quite distributed. (sorry I am not very sure with this answer)
3a) Independent variable is time, Dependent variable is distance.
3b) See attachment.
3c) Linear
3d) 2.5s: 10m 6.25s: 25m 8s: 32m
3e) 3m: 0.75s 21m: 5.25s. 36m: 9s.
Step-by-step explanation:
1a) Mean = (74+71+68+84+54+60+64+68+65+64)/10 kg = 67.2 kg
1b) Sort the data in ascending order (in kg).
54 60 64 64 65 68 68 71 74 84
Median = (65+68)/2 kg = 66.5 kg
1c) Mode = 64 kg, 68 kg (both appeared twice)
2a) Mean = (45+52+47+55+62+80+71+60+84+57+46+50+48+61+49+63+54+49+72)/19 m = 58.1m (correct to 1 decimal place)
Arrange the data in ascending order (in m).
45 46 47 48 49 49 50 52 54 55 57 60 61 62 63 71 72 80 84
Median = 55m
Mode = 49m (appeared twice)
2b) See answer.
3a) Independent variable is the variable that is to be changed. Dependent variable is the variable that is to be measured.
3b) Just plot the graph.
3c) Distance = 4 x time
3d) 2.5 x 4 = 10m. 6.25 x 4 = 25m. 8 x 4 = 32m.
3e) 3/4=0.75s. 21/4=5.25s. 36/4=9s.

A landscaping company placed two orders with a nursery. The first order was for 13 shrubs and 4 trees and totaled 487. The second order was for 6 scrubs and 2 trees,and totaled 232. The bills do not list the per-item price. What were the costs of one shrub of one tree?
Answer:
Cost of shrubs = 23
Cost of tree = 47
Step-by-step explanation:
Let
Cost of shrubs = x
Cost of tree = y
13x + 4y = 487 (1)
6x + 2y = 232 (2)
Multiply (2) by 2
12x + 4y = 464 (3)
13x + 4y = 487 (1)
Subtract (3) from (1)
13x - 12x = 487 - 464
x = 23
Substitute x = 23 into (2)
6x + 2y = 232 (2)
6(23) + 2y = 232
138 + 2y = 232
2y = 232 - 138
2y = 94
y = 94/2
= 47
y = 47

"what quadrant is...." PLEASE PLEASE HELP!!!! Thank you so so much!!! *will give brainliest*
Given:
[tex]\tan \theta > 0[/tex] and [tex]\sec \theta <0[/tex].
To find:
The quadrant.
Solution:
We know that,
In I quadrant, all trigonometric ratios are positive.
In II quadrant, only [tex]\sin \theta, \text{cosec}\theta[/tex] are positive and others are negative.
In III quadrant, only [tex]\cot \theta, \tan\theta[/tex] are positive and others are negative.
In IV quadrant, only [tex]\cos \theta, \sec\theta[/tex] are positive and others are negative.
We have,
[tex]\tan \theta > 0[/tex] and [tex]\sec \theta <0[/tex].
Here, [tex]\tan \theta[/tex] is positive and [tex]\sec \theta[/tex] is negative. So, [tex]\theta [/tex] lies in the III quadrant.
Therefore, the correct option is C, i.e., III.
