Using the knowledge of the total sum of the internal angles of a triangle, the value of x would be 25
Recall :
A + B + C = 180° (Sum of the internal angles of a triangle)Hence,
(x + 15) + (3x - 35) + 4x = 180
x + 15 + 3x - 35 + 4x = 180
8x - 20 = 180
8x = 180 + 20
8x = 200
x = 200 / 8
x = 25°
Therefore, the value of x is 25

=(−1)2−4(1)(6)
=−23
Answer:
−23
Answer:
no solution
Step-by-step explanation
[tex]x^{2}-x+6=(x^{2}-2.\frac{1}{2}x+\frac{1}{4})+6-\frac{1}{4}=(x-\frac{1}{2})^{2}+\frac{23}{4}[/tex]
see : [tex](x-\frac{1}{2})^{2}\geq 0 => (x-\frac{1}{2})^{2}+\frac{23}{4}\geq 0+\frac{23}{4}>0[/tex]

b
15. C
13. a
14. b
Answer:
a + 112 + 33 = 180 ( sum of interior angles of tria
or a + 145 = 180 - ngle is 180 degrees)
or a = 180 - 145
or a = 35 .
similarily,
c + 43 + 71 = 180
or c + 114 = 180
or c = 180 - 114
or c = 66 .
and ,
a + 71 + b = 180 ( sum of angles in straight line is or, 35 +71 + b = 180 180 degrees)
or , b + 106 = 180
or, b = 180 - 106
or, b = 74 .

A 10 foot ladder leans against a building that is 8 feet off of the ground. At what height would a 25 foot ladder touch the building if both ladders form the same angle with the ground?
Answer:
19.99feetStep-by-step explanation:
The set up will form a right angles triangle:
First we need to get the angle of elevation of the first ladder using SOH, CAH, TOA
The length of the ladder will be the hypotenuse = 10foot
The opposite will be the height of the building = 8ft
Using Sin(theta) = opposite/hyp
sin Theta = 8/10
theta = sin^{-1}0.8
theta = 53.13°
If the length of the ladder is now 25 foot, the height of the building will be calculated as shown;
sin Theta = h/25
sin53.13 = h/25
h = 25sin53.13
h = 19.99feet
Hence the height of the building will be 19.99feet

Jaxson was filling his pool. When he started, it already contained 486 gallons. He filled it for 95 minutes with water coming out of a hose at a rate of 8.4 gallons per minute. How many gallons of water are in the pool at the end of 95 minutes.Immersive Reader
Answer:
1284 gallons
Step-by-step explanation:
The swimming pool already contained 486 gallons.
Then, Jaxson filled the pool for 95 minutes, so, the total amount of water in the pool at the end of 95 minutes = 486 + filled amount in 95 minutes.
The rate of filling water is 8.4 gallons per minute. i.e
In 1 minute, the amount of water filled = 8.4 gallons.
So, by using the elementary method, in 95 minutes, the amount of water filled = 8.4 x 95 = 798 gallons.
So, the total amount of water in the pool at the end of 95 minutes
=486 + 798 = 1284 gallons.

Caroline is planting flowers in her garden. She plants her first 7 flowers in 4 minutes. After 12 minutes, she has planted 21 different flowers.
Which equation represents this direct variation?
The answer is B) y= 7/4x
This is because when you graph it you would go up 7 and over 4- you just had to find the rise over run. I also just made sure it was correct on edmentum!
Caroline is planting her first 7 flowers in 4 minutes and then past 12 minutes, she plants 21 different flowers. That suggests that she is planting the flowers following the given equation y=(7/4)x.
What is dependant variable?The dependent variable is defined as the variable whose evaluation of the independent variable determines the quality of the dependent variable. That is, it is consistently claimed that the word variable's estimate depends on the mathematical condition's free variable.
How to solve it?Let Caroline plant y flowers in x minutes.
By using the unitary method we can observe that
4 minutes → 7 flowers
⇒ 1 minute → 7/4 flowers
⇒ x minutes → (7/4)x flowers
Hence, Caroline is planting y=(7/4)x flowers in x minutes. And y=(7/4)x this equation represents the variation perfectly.
NOTE: We took the number of flowers planted as y because it is a dependent variable. The number of flowers depends on the time elapsed.

Un bloque de 2kg es trasladado a lo largo de la superficie lisa por accion de una fuerza f=40N ¿cual es el trabajo realisado por la fuerza "f"y por la fuersa de gravedad para un recorrido de 6m?
Explicación paso a paso:
Workdone = Fuerza * distancia movida en la dirección de la fuerza
Dado
Fuerza f = 40N
Distancia = 6 m
El trabajo realizado por la fuerza F es:
Trabajo hecho = 40 * 6
Trabajo terminado = 240 Nm
El trabajo realizado por la fuerza de la gravedad es el trabajo realizado por el cuerpo de 2 kg:
W = mg
W = 2 * 10
W = 20N
Trabajo realizado = 20 * 6
Trabajo terminado = 120 Nm
When a polynomial 2x^3+3x^2+ax+b is divided by (x-2) leaves remainder 2, and (x+2) leaves remainder -2.Find a and b.
p(x) = 2x³ + 3x² + ax + b when divided by x - 2 and x + 2 leaves the remainders 2 , - 2.
Find:Value of a and b
Solution:✯ g(x) = x - 2
⟹ 0 = x - 2 [ g(x) = 0 ]
⟹ x = 2
★ p(2) = 2(2)³ + 3(2)² + a(2) + b
⟹ - 2 = 2 * 8 + 3 * 4 + 2a + b
⟹ - 2 - 16 - 12 - 2a = b
⟹ - 30 - 2a = b -- equation (1)
Similarly,
✯ g(x) = x + 2
⟹ 0 = x + 2
⟹ x = - 2
★ p( - 2) = 2( - 2)³ + 3( - 2)² + a ( - 2) + b
Substitute the value of b from equation (1).
⟹ 2 = 2 * ( - 8) + 3 * 4 - 2a - 30 - 2a
⟹ 2a + 2a = - 16 + 12 - 2 - 30
⟹ 4a = - 24
⟹ a = - 24/4
⟹ a = - 6
Substitute the value of a in equation (1).
⟹ - 30 - 2( - 6) = b
⟹ - 30 + 12 = b
⟹ - 18 = b
Therefore,
a = - 6
b = - 18.
I hope it will help you.

The PTA is trying to raise money for an end of the year carnival for a local
school. They are selling t-shirts, s, for fundraisers. Their revenue equation is
represented by the equation below. As a reminder, the revenue equation
describes how much money is brought in during the fundraiser: r(s) = - .1552 +30s
Their expenses equation is represented by: e(s) = 3s + 200.
A. Find the value of r(s) = e(s)
I
B. Explain what this means in the context of the problem.
Solution:
The revenue is the amount of money gotten by selling goods and products while expenses is the amount of money spent to produce the goods or products.
The revenue is given as:
r(s) = - 0.1552 +30s
While the expenses is given as:
e(s) = 3s + 200.
Since r(s) = e(s), therefore:
3s + 200 = -0.1552 + 30s
30s - 3s = 200 + 0.1552
27s = 200.1552
s = 7.4
s ≈ 7
At break even the expenses and revenue are equal to each other.
This means that if 7 t shirts are produced then the PTA would be at break even.
