Skylar travels 50 meters N and then goes 30 meters W before coming straight back south 20 meters. What distance did she travel?Skylar travels 50 meters N and then goes 30 meters W before coming straight back south 20 meters. What distance did she travel?
Answer:
100 meters
Step-by-step explanation:
Given that:
Distance traveled N = 50 meters
Distance traveled W = 30 meters
Distance traveled straight back south = 20 m
The distance traveled :
Distance traveled N + Distance traveled W + Distance traveled S
(50 + 30 + 20) meters
= 100 meters

Given the roots of 4 and -2 find the equations of the quadratic.
4 points
Answer:
p(x) = x² - 2x -8
Step-by-step explanation:
We need to find the quadratic equation with roots 4 and -2 , we know that if a and ß are the roots of equⁿ , then the polynomial is ,
[tex]\implies p(x) =k[ x^2-(\alpha + \beta)x+\alpha\beta] [/tex]
Where k is constant . Substitute respective values ,
=> p(x) = k [ x² - ( a + ß )x + aß ]
=> p(x) = k [ x² - ( 4-2) x + (4)(-2) ]
=> p(x) = k [ x² -2x - 8 ]
If k = 1 ,
=> p(x) = x² - 2x - 8

I cant seem to figure this out. Help
Answer:
108 cm^2
Step-by-step explanation:
This solid is a triangular prism.
The total surface area is made up of the area of 5 faces.
The front and rear faces are called the bases and are two congruent triangles.
The other three faces are three rectangles and form the lateral area.
SA = area of bases + lateral area
The area of the bases is 2 times the area of a triangle.
The lateral area is the sum of the area of the three lateral faces, 3 rectangles, and is also the product of the perimeter of the base and the height of the prism.
SA = 2 * bh/2 + PH
where
b = base of triangular base,
h = height if triangular base,
P = perimeter of the base, and
H = height of the prism
SA = 2 * (3 cm)(4 cm)/2 + (3 cm + 4 cm + 5 cm) * (8 cm)
SA = 12 cm^2 + 96 cm^2
SA = 108 cm^2
5) Mario owns a plumbing business. He charges an hourly rate plus a onetime set up fee. His first job was 4 hours and he charged $450. His second job was 3 hours and he charged $675. If his set up fee is $150, how much does he charge per hour?
Answer:
Results are below.
Step-by-step explanation:
First, we need to calculate the variable income per job:
First job= 450 - 150= 300
Second job= 675 - 150= 525
Now, the hourly rate:
Hourly rate= total variable income / number of hours
First job= 300 / 4= $75
Second job= 525 / 3= $175
It is probably that the second job was 7 hours long. If not, he doesn't charge the same amount per hour
please answer with steps
Answer:
both of these.will be solved by angle sum property which states that sum of all interior angles is 180 degrees
in a
one angle is 30 degrees
other is right angle means 90 degrees
total sum of these angles is 120
total sum of all angle must be 180 degrees
so the third angle is 60 degrees
in b
one angle is 45 degrees
other is a right angle means 90 degrees
total sum of these angles is 135
total sum of all angles must be 180 degrees
so the third angle is 45 degrees
hope this helps

A customer buys a CD for $15 and a video game. The customer pays a total of $42.80 for the two items, which includes 7% sales tax. Which equation can be used to find x, the cost of the video game before tax? 0.07 (15 + x) = 42.80 0.07 (42.8 minus 15) = x 1.07 (15 + x) = 42.80 1.07 (42.8 minus 15) = x
Answer:
1.07 (15 + x) = 42.80
Step-by-step explanation:
Given data
CD= $15
Let the cost of the video game be x
The total cost= 15+x
Hence the equivalent expression is
1.07 (15 + x) = 42.80
open bracket
16.05+1.07x= 42.80
42.80-16.05= 1.07x
26.75=1.07x
x= 26.75/1.07
x= 25
Check
7% tax for CD
=0.07*15
=1.05
total =1.05+15
=$16.05
7% tax for Video game
=0.07* 25
=1.75
total =1.75+25
=$26.75
In all
=26.75+16.05
=$42.8
find a, b and c such that the number a , 7,b,23,c are in A.P please solve it
Answer:
since a,7,b,23,c are in A.P.
first term t1=a
second term t2=7
common difference (d)=7-a
forth term t4=a+3d
23=a+3(7-a)
23=a+21-3a
23=21-2a
2a=21-23
a=-2/2=-1
common difference =7-a=7--1=8
third term =a+2d=-1+2×8=15
:.b=15
5th term =c
a+4d=c
c=-1+4×8=31
a=-1
b=15
c=31
