Solve for the value of k. (k+8) 400
Answer: The answer to this math question about solving for the value of k with the given full of the angles is k = 6.
Step-by-step explanation: As always to remember, all of the forming angles to a straight line with a sum of 180 degrees, so anyways, here are 6 steps in order to solve for the value of k:
Step 1. First, let's find the measures of the value of all 3 angles, the measures of all 3 angles are, 8°, 90°, and 40° that looks in the equation form like this: [tex]7k + 8 + 90 + 40 = 180.[/tex]
Step 2. Next, after finding the measures of the value of all 3 angles, it's time to add all 3 angles up together that looks in the equation form like this: [tex]7k + 138 = 180.[/tex]
Step 3. Then, let's move positive 138 to the right side so you got negative 138, and keep the positive 180 the same when moving to the left side that looks in the equation form like this: [tex]7k = 180 - 138.[/tex]
Step 4. In addition to that, after moving positive 138 to the right side so you got negative 138, and keep the positive 180 the same when moving to the left side, it's time to subtract 138 degrees and 180 degrees that looks in the equation form like this: [tex]7k = 42.[/tex]
Step 5. Now last but not least is finally, after subtracting 138 degrees and 180 degrees, it's time to divide the both sides by 7 that looks in the equation form like this: [tex]\frac{7k}{7}=\frac{42}{7}.[/tex]
Step 6. Hence the value of k is 6.
I hope that my full given answer with my full given step-by-step explanation is very helpful to your own math question about solving for the value of k with the given full of the angles, please mark me as Brainliest, take care, always be safe, and have a great rest of the day and a great weekend! :D

A clothing store owner tracks the amount of money the last 10 customers spend in her store. The owner concludes that the typical amount spent by any customer is $28.80. The owner's conclusion
A) is valid. The last 10 customers only bought sale items.
B) is correct. This is the average amount spent by any customer.
C) is invalid. This is not a good representation of all customers.
D) is unfair. The last ten people in the store may have been tired.

Please help! Thanks!
Step-by-step explanation:
Put the what given of y in equation 2 to equation of 1
So you get
[tex] \frac{4}{5} x + \frac{2}{5} x - 7 = - 4 \\ \frac{6}{5} x = 3 \\ x = \frac{15}{6 } \\ x = \frac{5}{2} [/tex]
Then put the value of x in second equation
You will get
[tex]y = - \frac{2}{5} \times \frac{5 }{2} + 7 \\ \\ y = 6[/tex]
- 10x - 5y = 5 - 4x + 5y = 23
The given polygons are similar. Find the value of x.
Answer:
x= 10 hope it helps have a nice day
Answer:
x=10
Step-by-step explanation:
[tex]\frac{8}{12} =\frac{x}{15}[/tex]
8×15=12x

You kayak up a river at a rate of 36 feet every 30 seconds. You kayak 304 feet every 2 minutes on the way back down the river. How much farther do you kayak in 5 minutes on the way down the river than in 5 minutes on the way up the river?
Answer:
400 feet
Step-by-step explanation:
on way up you travel 35 ft in 30 sec or 144 ft in 120 sec (2 min)
on way down you travel 304 ft in 120 sec (2 min)
the distance traveled for 5 minutes at rate from way 'up' is 360 feet
the distance traveled for 5 minutes at rate from way 'down' is 760 feet
difference is 400 feet
Answer:
400

If a person's speed doubles and all else remains the same, what will be the person's angular momentum
Answer:
The person's angular momentum will be double
Step-by-step explanation:
Let
Speed of person=v
Mass of person=m
Radius=r
Speed of person=2v
We have to find the person's angular momentum when the speed of person is double and all else remains same.
We know that
Angular moment ,L=mvr
Using the formula
Angular momentum of person when speed 2v
L'=m(2v)r
[tex]\frac{L'}{L}=\frac{m(2v)r}{mvr}=2[/tex]
[tex]L'=2L[/tex]
Hence, the angular moment of person will be double when the speed of person is double.

Solve the system of equations by substitution. Show your work in the sketch and write your answer as an ordered pair.
There are 2 sketches in case you need more room.
`-3x+y=-2`
`y=4x`
Let's solve your system by substitution.
−3x+y=−2;y=4x
Rewrite equations:
y=4x;−3x+y=−2
Step: Solvey=4xfor y:
y=4x
Step: Substitute4xforyin−3x+y=−2:
−3x+y=−2
−3x+4x=−2
x=−2(Simplify both sides of the equation)
Step: Substitute−2forxiny=4x:
y=4x
y=(4)(−2)
y=−8(Simplify both sides of the equation)
Answer:
x=−2 and y=−8

How do you know
the quotient of 639 /
6 is greater than
100 before you actually divide
Answer:
because since the question is 639 / 6
we immediately know that 600 / 6 is 100
639 / 6 = 106.5
Answer:
You just need a little conversion to get the answer.
[tex]\frac{639}{6}=\frac{600}{6}+\frac{39}{6}\\ = 100+\frac{39}{6} >100[/tex]

CAN SOMEONE PLEASE HELP THIS IS DUE AT MIDNIGHT (I’ll give brainlist)
Answer:
d° = 62°
e° = 90°
f° = 27°
g° = 27°
h° = 118°
j° = 62°
k° = 63°
Step-by-step explanation:
The relationship between the given angles are;
k° = 63° (Vertically opposite angles)
63° + f° = 90° (Given complementary angles)
∴ f° = 90° - 63° = 27°
f° = 27°
g° = f° (Vertically opposite angles)
∴ g° = f° = 27°
g° = 27°
e° + 63° + f° = 180° (The sum of angles on a straight equals 180°)
∴ e° = 180° - (63° + r°) = 180° - (63° + 27°) = 90°
e° = 90°
h° = 118° (Vertically opposite angles)
118° + d° = 180° (The sum of angles on a straight equals 180°)
∴ d° = 180° - 118° = 62°
d° = 62°
j° = d° (Vertically opposite angles)
∴ j° = d° = 62°
j° = 62°
Gabby has $1,506 in a savings account that pays 2.5% simple interest. How much interest will she earn in 3 years?
Answer:
$112.95
Step-by-step explanation:
Use the simple interest formula, I = prt
Plug in the initial amount, interest rate, and number of years
I = prt
I = (1506)(0.025)(3)
I = 112.95
So, the interest created in 3 years is $112.95
shine sold two tables at 9900 rupees each.he got 10% profit in one sale and 10% loss in the other.did the total sale result in a profit or loss? what percentage? please give me step by step explanation
the total sale was neither a profit nor loss , 0%
Step-by-step explanation:
1st table :
100%-> 9900
110%-> 10890
10890-9900=990(earned)
------------------------------------------
2nd table :
100%->9900
90%-> 8910
9900-8910=990(lost)
990-990=0
hence the total sale was neither a profit nor loss , 0%
An older person is 4 years older than 7 times the age of a younger person. The sum of their ages is 44. Find their ages
Answer:
5 yr and 39 yr
Step-by-step explanation:
Let x = the age of the younger
then 7x + 4 = the age of the older
Now x + 7x + 4 = 44
8x + 4 = 44
8x = 40
x = 5
7x + 4 = 7(5) + 4 = 35 + 4 = 39
Check: 5 + 39 = 44
