Answer:
tanA = 40/9
Step-by-step explanation:
Try to construct a right-angled triangle with it's adjacent side=9 and hypotenuse = 41,
By pyth. theorem, we can get the remaining side (opposite side)
= √(41^2 - 9^2)
= 40
tanA = oppside side/ adjacent side
tanA = 40/9

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

Circle the smaller number: 0.123 0.13. Explain how to use the grids below to support your answer.
Answer: The smallest number is 0.123
Step-by-step explanation:
We want to find the smallest number between:
0.123 and 0.13
To do it, we first need to look at the largest digit of each number and see which one is larger.
In both cases we can see that the largest digit for both numbers is the first digit after the decimal point.
For both numbers this digit is 1, so we can't conclude nothing yet.
Now we need to look at the next digit.
For 0.123, the second digit is 2.
For 0.13 the second digit is 3.
Then the second digit is larger for 0.13, this means that 0.123 is the smallest number.
I can not explain you how to use the grids below because i can not see them in the question.

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
have a good day
thanks for points

Answer:
691
Step-by-step explanation:
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

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

Wyatt and his little sister are saving up money to buy a joint birthday present for their mother. Wyatt already has $20 saved and plans to save $7 per week from his allowance. His sister has $14 saved so far and will save $9 per week from hers. The two siblings will soon have saved the same amount towards their mother's gift. How much will each one have saved? How long will that take?
Answer:
The two siblings will have saved the same amount towards their mother's gift after 3 weeks.
Amount saved by Wyatt = [tex]\$41[/tex]
Amount saved by Wyatt's sister = [tex]\$41[/tex]
Step-by-step explanation:
Let [tex]t[/tex] (in weeks) denotes the time period by which the two siblings will have saved the same amount towards their mother's gift.
Wyatt already has $20 saved and plans to save $7 per week from his allowance.
Amount saved by Wyatt = [tex]20+7t[/tex]
Wyatt's sister has $14 saved so far and will save $9 per week from hers.
Amount saved by Wyatt's sister = [tex]14+9t[/tex]
To find the time period by which the two siblings will have saved the same amount towards their mother's gift,
solve the following equation.
[tex]20+7t=14+9t\\20-14=9t-7t\\6=2t\\3=t[/tex]
So, the two siblings will have saved the same amount towards their mother's gift after 3 weeks.
Amount saved by Wyatt = [tex]20+7(3)=20+21=\$41[/tex]
Amount saved by Wyatt's sister = [tex]14+9(3)=14+27=\$41[/tex]
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

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
