Angle m∠8 =41° and x=10°

Step-by-step explanation:

Given that m∠3=139° then

m∠3=m∠1 = corresponding angles = 139° and m∠7=m∠5=m∠3=139°

m∠8= 180°-139° =41° -sum of angles on a straight line

m∠8=m∠6=m∠4=m∠2= 41°

2.

Given that m∠3=8x+70° and  m∠8=4x-10° then you can find the value of x as;

m∠3+m∠8=180°

8x+70°+4x-10°=180°

12x+60°=180°

12x=180°-60°

12x=120°

12x/12 =120°/12

x=10°

Hence,

m∠3=8x+70° = 8*10 +70° = 80°+70°=150°

m∠8= 4x-10° = 4*10 - 10° = 40°-10° =30°

m∠1 =m∠3 = m∠5 = m∠7 =150°

m∠2 = m∠ 4 = m∠6 = m∠8 =30°

Bryce has heard that gas appliances are cheaper to use and can lower utility costs. He is interested in purchasing a new gas sto
Bond [772]

Answer:

C. $29.20

Step-by-step explanation:

The difference between using an electric stove and a gas stove everyday is 13 cents - 5 cents= 8 cents.

Saving 8 cents everyday.

Therefore for a year, Bryce will save 8 cents × 365days = 2920 cents

Then 2920 cents = $(2920÷100)

=$29.20

Please help with the steps as well!!

To solve this problem, we need to use the Pythagorean Theorem, which states that a^2 + b^2 must equal c^2. "a" is the length of one of the legs (shorter sides of the triangle) and "b" is the length of the other leg. "c" is the length of the hypotenuse.

a = y = 36.25cm

b = x = 20.93cm

a^2 + b^2 = c^2

(36.25)^2 + (20.93)^2 = c^2

1314.0625 + 438.0649 = c^2

√1752.1274 = √c^2

c = 41.8584209 ≈ 41.86

So your final answer is...

The length of the hypotenuse is about 41.86 cm.

Part 1
svetlana [45]

Answer:

A: This polynomial has a degree of 2 , so the equation 12x2+5x−2=0 has two or fewer roots.

B: The quadratic equation 12x2+5x−2=0 has two real solutions, x=−2/3 or x=1/4 , and therefore has two real roots.

Step-by-step explanation:

f(x) = 12x^2 + 5x - 2.

Since this is a quadratic equation, or a polynomial of second degree, one can easily conclude that this equation will have at most 2 roots. At most 2 roots mean that the function can have either 2 roots at maximum or less than 2 roots. Therefore, in the A category, 2nd option is the correct answer (This polynomial has a degree of 2 , so the equation 12x^2 + 5x − 2 = 0 has two or fewer roots).

To find the roots of f(x), set f(x) = 0. Therefore:

12x^2 + 5x - 2 = 0. Solving the question using the mid term breaking method shows that 12*2=24. The factors of 24 whose difference is 5 are 8 and 3. Therefore:

12x^2 + 8x - 3x - 2 = 0.

4x(3x + 2) -1(3x+2) = 0.

(4x-1)(3x+2) = 0.

4x-1 = 0 or 3x+2 = 0.

x = 1/4 or x = -2/3.

It can be seen that f(x) has two distinct real roots. Therefore, in the B category, 1st Option is the correct answer (The quadratic equation 12x2+5x−2=0 has two real solutions, x=−2/3 or x=1/4 , and therefore has two real roots)!!!
