Step-by-step explanation:
[tex] \sf{x + 30 ° + 100 ° + 3x - 10 ° = 180 °}[/tex]
( Sum of angle in straight line )
Collect like terms
⇒[tex] \sf{4x + 30 ° + 100 ° - 10 ° = 180 °}[/tex]
Calculate the sum or difference
⇒[tex] \sf{4x + 120 ° = 180 °} [/tex]
Move 120 to right hand side hand change it's sign
⇒[tex] \sf{4x = 180 ° - 120 °}[/tex]
Subtract 120 from 180
⇒[tex] \sf{4x = 60 ° }[/tex]
Divide both sides of the equation by 4
⇒[tex] \sf{ \frac{4x}{4} = \frac{60}{4} }[/tex]
Calculate

Hope I helped!
Best regards!!
Explanation:
(x + 30) + 100 + (3x - 10) = 180 (straight angle)
x + 30 + 100 + 3x - 10 = 180
4x + 120 = 180
4x = 180 - 120
4x = 60
x = 60/4
x = 15 degree
Therefore, x = 15 degree

¿Un camión de carga lleva 32 costales de maíz de 20.5 Kg. Cada uno y 19 con un peso de 48.75 Kg. Cada uno. ¿Cuántos kilogramos de maíz lleva el camión?
Answers
Answer:
1,582.25 kilogramos
Step-by-step explanation:
Para determinar los kilogramos de maíz que lleva el camión, se debe multiplicar el peso de los dos tipos de bultos que lleva por la cantidad de cada uno y sumar estos valores para obtener la respuesta:
(20.5*32)+(48.75*19)=656+926.25=1,582.25
De acuerdo a esto, el camión lleva 1,582.25 kilogramos de maíz.
In a theater, there are 20 chairs in the first row, each row has 4 more chairs than the previous row, and there are 15 rows. How many chairs are there in the theater?
Answers
Answer:
There are a total of 720 chairs in the theater
Step-by-step explanation:
First row = 20 chairs
Second row = 24 chairs
Third row = 28 chairs
The given is an arithmetic progression (A.P)
First term
a = 20
Common difference
d = 4
Number of terms
n=15
Sum of the chairs in the theater with a total of 15 rows
Sum of an A.P = n/2 { 2a + (n-1) d}
= 15/2{ 2*20 + (15-1) 4}
= 7.5 { 40 + (14) 4 }
= 7.5 { 40 + 56}
= 7.5(96)
=720 chairs

2 feet to 40 inches (ratios)
Answers
[tex]\boxed{3:5}[/tex]
We need to first change the measurement of 2 feet to inches, and then find the most simplified version of the resulting ratio.
2 feet = 24 inches (1 foot = 12 inches)
Ratio: 24:40
Simplify ratio:
24/8 = 3
40/8 = 5
Ratio: 3:5
Therefore, the simplified ratio is 3:5 inches.

Answers
Answer:
0.6 deg/s²
Step-by-step explanation:
Acceleration is the time rate of change of velocity, it is the ratio of velocity to time. The formula for acceleration is given by:
Acceleration = Change in velocity / time taken = (Final velocity - Initial velocity) / time
Given that the acceleration is 2160 deg/min², we have to convert it to deg/s²
1 min = 60 seconds
1 min² = 60² s² = 3600 s²
[tex]2160\ deg/min^2=\frac{2160\ deg}{1\ min^2*3600\ \frac{s^2}{min^2} }=0.6\ deg/s^2\\ \\2160\ deg/min^2=0.6\ deg/s^2[/tex]

Answer:
[tex]x=2,8[/tex]
Step-by-step explanation:
So we have the equation:
[tex]1+3|x-5|=10[/tex]
First, subtract 1 from both sides:
[tex]3|x-5|=9[/tex]
Now, divide 3 from both sides:
[tex]|x-5|=3[/tex]
Definition of absolute value:
[tex]x-5=3\text{ or }x-5=-3[/tex]
For the left, add 5 to both sides.
For the right, add 5 to both sides:
[tex]x=3+5\text{ or } x=-3+5\\x=8\text{ or }x=2[/tex]
Thus, the answers are:

What is the image of the point (8, -3) after a rotation of 90° counterclockwise about
the origin?
Answers
Answer:
[tex]\huge\boxed{(3, 8)}[/tex]
Step-by-step explanation:
When we rotate a point 90° counterclockwise around the origin, it's the same as rotating it 270° clockwise around the origin.
When we rotate something 270° clockwise around the origin, the original coordinates (x, y) becomes (-y, x).
y is -3, and -(-3) is just 3, since two negatives make a positive.
x just remains x, but it's in a different position.
This makes the new coordinate [tex](3, 8)[/tex].

It is a customer appreciation week at the vans shoe outlet, Which means all customers are given a 20% discount on all items. A customer comes in with an birthday coupon for an additional 10% off any shoe item, once the first discount has been applied. The customer buys 3 pairs of shoes for $120.00 each. After the two discounts how much does the customer pay?
Answers
Answer:
$278.40
Step-by-step explanation:
Note: "...an additional 10% off any shoe item, once the first discount has been applied." (emphasis added).
Note that the customer is buying 3 pairs of shoes for $120 each: 120 x 3 = $360
The first discount is the 20% discount (on every single item), the second discount is the 10% discount coupon of of any item (which signifies one item only).
Solve for the first discount:
$360 x 0.20 = $72
$360 - 72 = $288.
Next, divide $288 by 3 (to get the individual prices of the shoes:
$288/3 = $96.
The customer then uses a birthday coupon for one of the shoes, which gives an additional 10% off.
$96 x 0.10 = 9.6
$96 - 9.6 = $86.4
Remember, the other two shoes still cost $96 each. Add the price together:
$96 + $96 + $86.4 = $278.40
$278.40 will be the total.
